From 0dee3661b5c14a83109ab705562cc2ffa1e3768d Mon Sep 17 00:00:00 2001 From: Paul Dlug Date: Tue, 8 Sep 2026 08:27:05 -0700 Subject: [PATCH 001/255] feat(schema): structural subtyping predicate for projected JSON Schemas (#634) Adds `isStructuralSubtype(child, parent)` to `@nicia-ai/typegraph/schema`: a pure structural-subtyping predicate over the projected JSON Schema fragment TypeGraph already serializes for every node and edge. It answers one question, whether every value that satisfies `child` is guaranteed to satisfy `parent`, and returns a three-way verdict: `subtype`, `not-subtype` with the deepest failing reason and JSON path, or `incomparable` when either side carries a construct the projection cannot judge. An unjudgeable pair is refused, never accepted. The rule set is documented at the top of the module: width subtyping (a child may add properties, and the parent's `additionalProperties: false` is not applied to the child's extras), required parent properties stay required and narrower in the child, scalar constraints must be at least as tight (`integer` narrows `number`; enum subsets; bounds within), arrays and tuples compare item-wise including tuple tails, unions match member-wise with sibling keywords ANDed rather than replaced, and `format` is compared as a constraint because the Zod projection emits `format` with no `pattern` for validators such as `z.url()` and `z.jwt()`. Unknown keywords add no constraint, which is deliberately the opposite of the migration diff's rule (there an unrecognized key is user data whose change must be surfaced), and the module explains the difference. `$ref`, `allOf`, `not`, the standard JSON Schema keywords the predicate does not model, and nesting past a depth guard are all `incomparable`. This is not `isBreakingPropertyChange`. That function asks whether rows valid before a schema edit stay valid after it, and the two disagree in both directions over the same pair of schemas: a child that adds a required field is a subtype but a breaking migration; a child that relaxes a required field to optional is a safe migration but not a subtype. Four `migration.ts` helpers are promoted to exports so both predicates share one canonicalization; their bodies are unchanged. `JsonSchema` gains typed optional members for the keywords the predicate reads. Tests: a table-driven unit suite covering every rule in both directions, a projection-coverage suite that enumerates the keywords the Zod projection actually emits so a Zod upgrade that adds a keyword fails loudly, and fast-check properties for reflexivity, transitivity over tightening chains, and the two directions of the required-field rule. Each guarded rule was checked by mutating the rule and watching its table fail. The arbitraries live under `tests/property/arbitraries/` so the follow-up that wires this predicate into `subClassOf` validation can reuse them. The predicate is the foundation for validating `subClassOf` declarations against their schemas; that enforcement, and the typed `includeSubClasses` alias it enables, land separately. --- .changeset/structural-subtype-predicate.md | 7 + .../typegraph-adapters-drizzle-engine.api.md | 5 + ...ph-adapters-drizzle-postgres-pglite.api.md | 5 + ...typegraph-adapters-drizzle-postgres.api.md | 5 + ...raph-adapters-drizzle-sqlite-libsql.api.md | 5 + ...graph-adapters-drizzle-sqlite-local.api.md | 5 + .../typegraph-adapters-drizzle-sqlite.api.md | 5 + .../typegraph/etc/typegraph-backend.api.md | 5 + .../etc/typegraph-graph-merge.api.md | 5 + .../etc/typegraph-interchange.api.md | 5 + .../etc/typegraph-postgres-pglite.api.md | 5 + .../typegraph/etc/typegraph-profiler.api.md | 5 + .../typegraph/etc/typegraph-provenance.api.md | 5 + .../typegraph/etc/typegraph-schema.api.md | 27 + .../etc/typegraph-sqlite-local.api.md | 5 + packages/typegraph/etc/typegraph.api.md | 5 + packages/typegraph/src/schema/index.ts | 11 + packages/typegraph/src/schema/migration.ts | 18 +- .../src/schema/structural-subtype.ts | 956 +++++++++++++ packages/typegraph/src/schema/types.ts | 13 + .../typegraph/tests/property/arbitraries.ts | 339 +++++ .../tests/property/structural-subtype.test.ts | 151 ++ .../tests/structural-subtype.test.ts | 1230 +++++++++++++++++ 23 files changed, 2817 insertions(+), 5 deletions(-) create mode 100644 .changeset/structural-subtype-predicate.md create mode 100644 packages/typegraph/src/schema/structural-subtype.ts create mode 100644 packages/typegraph/tests/property/structural-subtype.test.ts create mode 100644 packages/typegraph/tests/structural-subtype.test.ts diff --git a/.changeset/structural-subtype-predicate.md b/.changeset/structural-subtype-predicate.md new file mode 100644 index 000000000..b5f50beb6 --- /dev/null +++ b/.changeset/structural-subtype-predicate.md @@ -0,0 +1,7 @@ +--- +"@nicia-ai/typegraph": minor +--- + +Add `isStructuralSubtype(child, parent)` to the `@nicia-ai/typegraph/schema` entrypoint: a pure structural-subtyping check over TypeGraph's projected JSON Schema fragment that answers whether every value satisfying `child` is guaranteed to satisfy `parent`.

Before this change every added ontology relation was `safe` and every removal `warning`, on both the schema-diff path and the graph-extension evolve path. Adding `disjointWith(Person, Organization)` to a store already holding a `Person` and a `Company` with the same id migrated as safe and backwards-compatible; the store then carried an axiom its data violated, and only `verifyConstraintFences()` would ever say so. Property-schema tightening on the same path has always been classified breaking and refused. This closes that asymmetry with one classifier and one probe. `classifyOntologyChanges` (new `src/schema/ontology-change.ts`) replaces the add/remove loop in `computeSchemaDiff` and owns the severity table. Adding `disjointWith`, `subClassOf`, `equivalentTo` or `sameAs` is `warning` and carries data probes computed as the delta between the before and after registries: newly propagated disjoint pairs, `kindWithSubClasses` uniqueness components that merged, and, for removals, edge kinds whose declared endpoint allowance shrank. Adding or removing `inverseOf` or `implies` is `breaking`, because both change what a default `expand` traversal returns; this is the same ruling the Operational Identity `sameIdAcrossKinds` flip already carries. `disjointWith` removal and the hierarchy relations stay `safe`, and a relation naming a kind the same commit removes is `safe` so `removeKinds()` is unaffected. `ChangeSeverity` is unchanged: `warning` now means "auto-migrates only if the data allows it". The probes execute as a schema-commit preflight inside the commit transaction, before the Operational Identity closure rebuild, on every path that commits a version: `ensureSchema`/`createStoreWithSchema`, `Store.evolve()`, and `migrateSchema()`. `composeSchemaCommitPreflight` in `schema/manager.ts` is now the one place the preflight step order is spelled. The probe reader is `verifyConstraintFences`' own audit, refactored into `auditConstraintFences` and parameterized by the proposed registry, so there is no second implementation of any violation predicate. The audit gains a fourth family, `edgeEndpointAssignability`, with a shared SQL builder for both dialects; the reader is chunked through a VALUES join under the bind budget and scoped to the current valid-time window. A refused tightening throws `MigrationError` with `reason: "ontology-tightening-violated"` and `details.violations` in exactly the shape `verifyConstraintFences()` returns. A backend that cannot commit a preflight atomically refuses with `ONTOLOGY_TIGHTENING_REQUIRES_ATOMIC_BACKEND`; a backend that omits the new audit family when it was requested is refused with `CONSTRAINT_FENCE_AUDIT_FAMILY_UNSUPPORTED` rather than reporting clean. The probe takes no additional lock. It carries the same residual window as the existing empty-kind fence: a writer committing under the previous schema version between the probe and the version CAS is not seen, and `verifyConstraintFences()` remains the post-hoc detector. The docs say so plainly. `computeSchemaDiff` and its read-only callers now propagate `ConfigurationError` when a diff touches ontology relations and either side's ontology cannot be validated; `requiresMigration()` treats "cannot classify" as "needs migration" so least-privilege routing still routes rather than crashes. The stored-document side of that is new behavior and the changeset describes the recovery path. The changeset carries a Breaking changes section (`ConstraintFenceViolation` gains a member without a claim `target`; custom backends implementing `readConstraintFenceViolations` must answer the new family) and Upgrade notes (`inverseOf`/`implies` changes need an explicit `migrateSchema()` even on clean data; the audit may surface pre-existing endpoint violations on databases that never ran it). `rollbackSchema` remains a known unprobed path: it flips the active pointer without a diff and can re-tighten an ontology; probing it needs its own design. --- .changeset/ontology-change-classification.md | 16 + apps/docs/src/content/docs/backend-setup.md | 17 +- apps/docs/src/content/docs/errors.md | 34 + apps/docs/src/content/docs/ontology.md | 43 + .../docs/src/content/docs/schema-evolution.md | 82 +- .../src/content/docs/schema-management.md | 11 +- .../typegraph-adapters-drizzle-engine.api.md | 20 + ...ph-adapters-drizzle-postgres-pglite.api.md | 19 + ...typegraph-adapters-drizzle-postgres.api.md | 19 + ...raph-adapters-drizzle-sqlite-libsql.api.md | 19 + ...graph-adapters-drizzle-sqlite-local.api.md | 19 + .../typegraph-adapters-drizzle-sqlite.api.md | 19 + .../typegraph/etc/typegraph-backend.api.md | 19 + .../etc/typegraph-graph-merge.api.md | 1638 ++--------------- .../etc/typegraph-interchange.api.md | 1333 ++------------ .../etc/typegraph-postgres-pglite.api.md | 1390 ++------------ .../typegraph/etc/typegraph-profiler.api.md | 1333 ++------------ .../typegraph/etc/typegraph-provenance.api.md | 1392 ++------------ .../typegraph/etc/typegraph-schema.api.md | 47 + .../etc/typegraph-sqlite-local.api.md | 1390 ++------------ packages/typegraph/etc/typegraph.api.md | 52 +- packages/typegraph/scripts/api-report.ts | 356 +--- .../backend/drizzle/operation-backend-core.ts | 125 +- .../operations/constraint-fence-audit.ts | 79 + .../backend/drizzle/operations/strategy.ts | 26 + packages/typegraph/src/backend/index.ts | 2 + packages/typegraph/src/backend/types.ts | 40 + packages/typegraph/src/errors/index.ts | 37 +- packages/typegraph/src/index.ts | 11 + packages/typegraph/src/registry/builders.ts | 19 +- .../src/registry/edge-endpoint-allowance.ts | 57 + packages/typegraph/src/registry/index.ts | 5 +- packages/typegraph/src/schema/deserializer.ts | 35 +- packages/typegraph/src/schema/index.ts | 12 + packages/typegraph/src/schema/manager.ts | 244 ++- packages/typegraph/src/schema/migration.ts | 147 +- .../typegraph/src/schema/ontology-change.ts | 676 +++++++ .../schema/ontology-tightening-preflight.ts | 176 ++ packages/typegraph/src/store/claims/axis.ts | 22 +- packages/typegraph/src/store/claims/verify.ts | 239 ++- packages/typegraph/src/store/store.ts | 58 +- .../tests/backends/integration-test-suite.ts | 2 + .../constraint-fence-verification.ts | 275 ++- .../tests/backends/integration/index.ts | 1 + .../integration/ontology-tightening.ts | 816 ++++++++ packages/typegraph/tests/identity.test.ts | 89 +- .../typegraph/tests/migration-diff.test.ts | 26 +- .../typegraph/tests/ontology-change.test.ts | 583 ++++++ .../schema-commit-preflight-order.test.ts | 98 + .../tests/temporal-builder-inventory.test.ts | 4 +- 50 files changed, 4901 insertions(+), 8271 deletions(-) create mode 100644 .changeset/ontology-change-classification.md create mode 100644 packages/typegraph/src/registry/edge-endpoint-allowance.ts create mode 100644 packages/typegraph/src/schema/ontology-change.ts create mode 100644 packages/typegraph/src/schema/ontology-tightening-preflight.ts create mode 100644 packages/typegraph/tests/backends/integration/ontology-tightening.ts create mode 100644 packages/typegraph/tests/ontology-change.test.ts create mode 100644 packages/typegraph/tests/schema-commit-preflight-order.test.ts diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md new file mode 100644 index 000000000..a2ede70dd --- /dev/null +++ b/.changeset/ontology-change-classification.md @@ -0,0 +1,16 @@ +--- +"@nicia-ai/typegraph": minor +--- + +Ontology changes are now classified by what they do to existing data, and a tightening the data violates is refused instead of auto-migrating.

This is new behavior for the stored (before) side of the diff: nothing previously validated a persisted schema document's registry unless the code-level graph rebuilt one from it, so a document persisted under an older, laxer validator can surface this refusal the first time a relation-touching commit is attempted against it — including, in principle, a fix-forward migration whose whole point is to remove the offending relation. There is no workaround for that case in this release; repair such a document through a path that does not diff ontology relations first. Every read-only caller built on `computeSchemaDiff` inherits this: `loadAndVerifyGraph` (and so `createVerifiedStore` / `assertSchemaCurrent`) and `getSchemaChanges()` now also throw `ConfigurationError` for the same unclassifiable-ontology documents. `requiresMigration()` is the one exception — as the least-privilege routing predicate, it treats "cannot classify" the same as "needs migration" and returns `true` instead of throwing, so a document only the privileged path can interpret still routes there rather than crashing the check meant to route it. + +### Breaking changes + +- `ConstraintFenceViolation` (from `store.verifyConstraintFences()` and the new `MigrationError` `"ontology-tightening-violated"` detail) gains an `edgeEndpointAssignability` member that carries `edgeKind`, `allowedPairs`, and `edges` instead of a claim `target`.

These -// helpers are implementation details behind the exported fluent surface; no -// forgotten name was removed, and exporting them would add API without an -// independent caller contract. -// Phase 4 adds eleven internal relation contract names behind the root's public -// fluent API: AggregateRelationFields, CompatibleRelationProjection, -// DerivedRelation, RelationAst, RelationColumn, RelationDefinition, RelationOrder, -// RelationProvenance, RelationSource, RelationState, and SetRelation. Root debt -// is 476 -> 487. The six Store-bearing secondary entrypoints also reference the -// root-only public ExecutableRelationQuery, PreparedBindings, -// PreparedParameterDeclaration, RelationColumnContext, RelationProjection, and -// RelationProjectionResult, giving each an exact +17 delta. No old names were -// removed, and these internal constructor/compiler types are not independent APIs. -// Phase 6 adds two internal qualified-path inference helpers at the root: -// RequiredRecursiveAliasValue and ResolvePathFormat (487 -> 489). The six -// Store-bearing secondary entrypoints additionally reach the root-exported -// BatchOnceOptions and five QualifiedRecursivePath* types, plus those same two -// helpers, for an exact +8 each. These names are the implementation graph behind -// the public opt-in batch option and qualified recursive-path result; the public -// caller types are exported at the root, while duplicating them across unrelated -// entrypoints would enlarge those surfaces. No forgotten name was removed. -// Ordered scalar collection adds one private factory name, `collect`, to the -// root expression object's inferred public shape (+1: 489 -> 490). The root -// directly exports its caller-facing `CollectOrder` type. The six secondary -// Store-bearing entrypoints render that type through the same expression -// surface without re-exporting it, so each gains `CollectOrder` instead (+1). -// No other forgotten-export set changes: the aggregate AST metadata and -// collection element metadata reuse types already present in those graphs. -// Splitting collection aggregation into its own public AST discriminant adds -// the internal `CollectExpressionNode` to the root and the same six -// Store-bearing secondary entrypoints (+1 each). `CollectOptions` is exported -// directly at the root and does not propagate into the secondary declaration -// graphs. Removing `"collect"` from `AggregateOperator` and `orderBy` from -// `AggregateExpressionNode` changes existing declarations without changing -// the forgotten-name set. No other entrypoint changes. -// Recorded revision requests add three public root types: -// `RecordedRevisionRequest`, `HistoryTransactionContext`, and -// `MeasurableHistoryTransactionContext`. The Store-bearing `./provenance`, -// `./sqlite/local`, and `./postgres/pglite` entrypoints render those root-only -// types transitively, so each gains exactly those three forgotten exports. -// The root names all three directly and gains no forgotten-export debt. -// Explicit multi-kind sources add FieldCategory to the root's reachable helper -// graph. Store-bearing secondary entrypoints also reference CommonPropertyKeys -// and NodePropsFor, which are exported by the root rather than repeated on each -// secondary surface. IsUnion is now shared with expression subqueries and keeps -// its existing forgotten-export name. Measured additions: +1 root, +3 on the -// six Store-bearing secondary entrypoints below; other surfaces are unchanged. -// Adopted schema evolution adds directly exported plan, option, outcome, and -// timeout types at their defining barrels. The API extractor also renders -// implementation-only owner/payload and backend adoption types transitively -// through Store and adapter signatures. These are booked as forgotten-export -// debt rather than widened as standalone package exports: they are not -// callable entrypoints or useful authoring contracts. After the six public -// plan/option types are directly exported from the root, root debt rises by -// four; -// Store-bearing secondary surfaces rise by six; backend adapter surfaces rise -// by two (one for the adoption result), and schema/engine surfaces by one. -// `branchForEvolution` is a direct graph-merge export; its transitive -// `EvolutionPlan` and Store evolution option types account for the additional -// graph-merge debt. The exact fingerprints below gate every changed surface. -// Planned evolution (#705) changes the type graph reachable through StoreEvolution: -// SchemaIdentity and the discriminated EvolutionRequirement union become named -// root/schema exports, while adapter authoring gains SchemaProvisioning and -// AdoptedSchemaWriteTransaction. The remaining entrypoint-specific changes below -// are exact symbol-set fingerprints, not a relaxed count-only allowance. -// Ordered record collections export CollectRecordFields, CollectedRecord, and -// CollectRecordOperand directly from the root. Six Store-bearing secondary -// entrypoints reach only CollectRecordOperand transitively, adding exactly -// that one forgotten name to each fingerprint below. Removing that name from -// each measured symbol set reproduces its previous fingerprint. -// Partitioned top-N introduces TopPerPartitionRelation as a transitive -// forgotten export at the root. Six Store-bearing secondary entrypoints also -// reach TopPerPartitionOptions and TopPerPartitionOrder without exporting them -// directly. Removing these exact new names from each measured symbol set -// reproduces its previous fingerprint; all other entrypoints are unchanged. -// Shared capability upgrades add ContributionScope and node-candidate query -// contracts to Store-bearing entrypoints, while endpoint-set conformance adds -// its fixture types and a bundle-member helper. These declarations are -// intentionally public or transitively reachable from public signatures; the -// updated hashes below record the exact measured name sets from this run. -// Array membership and tuple cursor predicates add their AST nodes to the -// public query graph.

Before this change three code paths answered differently. Disjointness expansion treated equivalent kinds as one class, write-path assignability and `includeSubClasses` ignored equivalence entirely, and `graph-merge` kept a third private closure that folded equivalence into subsumption for type reconciliation. With `equivalentTo(Company, Corporation)` and `disjointWith(Person, Company)`, a `Corporation` node was refused as if it were a `Company`, but was not accepted where a `Company` was expected and was not returned by a `Company` query. OWL 2 defines `equivalentClass` as mutual `subClassOf`; this makes TypeGraph's vocabulary mean what it borrowed. `KindRegistry` now collapses each equivalence class to one representative before the `subClassOf` transitive closure runs, so `isAssignableTo`, `isSubClassOf`, `expandSubClasses`, `getSubClassComponent`, and disjointness propagation agree by construction. Subsumption stays strict: a kind is never its own subclass and `expandSubClasses` lists each kind once. External IRIs are inert references and never enter the subsumption fold; a class of one kind plus IRIs folds to nothing, and `subClassAncestors` and `subClassDescendants` remain exact inverses (pinned by a property test over generated ontologies with IRIs). `graph-merge/closures.ts` is deleted and `reconcileTypes` consumes the store's own validated registry, so a merge and a query can no longer disagree about which kinds are the same class; every kind-name ordering on that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI. An equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. The deprecated `sameAs` alias behaves identically at runtime and is not widened. Behavior changes, listed in the changeset's Breaking changes section: `includeSubClasses: true` on `from()`, `to()`, and `search()` returns equivalent kinds; edge endpoints and the `implies`/`inverseOf` endpoint checks accept equivalents; a `kindWithSubClasses` uniqueness constraint spans the equivalence class, with the claim axis moving to the code-point minimum of the widened component and no data migration required because the probe reads the axis plus every covered kind; the serialized closures and schema hash change for graphs that declare equivalence, resolving as a semantic no-op on both boot paths. Follow-ups named rather than folded in: a repo-wide code-point ordering sweep beyond the kind-name sites this change owns; unifying the uniqueness probe's root-ancestor selection with the registry's component (it takes the narrow non-recursive fix here, keeping the existing claim-axis property pins); a document-scoped classifier for graph-extension validation; collapsing the merge planner's two ontology sources into one; and refreshing the stored schema hash in place when a diff has no semantic changes. --- .changeset/equivalence-is-subsumption.md | 14 + apps/docs/src/content/docs/graph-merge.md | 17 +- apps/docs/src/content/docs/ontology.md | 127 +++++-- apps/docs/src/content/docs/overview.md | 2 +- apps/docs/src/content/docs/queries/source.md | 4 +- .../docs/src/content/docs/queries/traverse.md | 2 +- packages/typegraph/etc/typegraph.api.md | 2 +- packages/typegraph/src/constraints/index.ts | 47 ++- .../typegraph/src/graph-extension/errors.ts | 9 + .../typegraph/src/graph-merge/closures.ts | 167 -------- packages/typegraph/src/graph-merge/merge.ts | 33 +- .../src/graph-merge/type-reconcile.ts | 110 ++---- .../src/graph-merge/typegraph-internal.ts | 11 +- .../typegraph/src/graph-merge/union-find.ts | 5 +- .../typegraph/src/ontology/core-meta-edges.ts | 13 +- packages/typegraph/src/ontology/validation.ts | 127 +++++++ .../typegraph/src/registry/build-validated.ts | 17 +- .../typegraph/src/registry/kind-registry.ts | 357 ++++++++++++++++-- packages/typegraph/src/schema/deserializer.ts | 12 +- packages/typegraph/src/store/claims/axis.ts | 4 +- packages/typegraph/test-d/ontology.test-d.ts | 56 +++ .../tests/backends/integration-test-suite.ts | 2 + .../tests/backends/integration/index.ts | 1 + .../integration/ontology-equivalence.ts | 129 +++++++ .../tests/graph-merge/closures.test.ts | 309 --------------- .../tests/graph-merge/type-reconcile.test.ts | 305 ++++++++++++++- .../typegraph/tests/migration-diff.test.ts | 65 ++++ .../tests/ontology-hardening.test.ts | 318 +++++++++++++++- .../tests/property/claim-axis.test.ts | 228 +++++++++-- .../tests/property/kind-registry.test.ts | 174 +++++++++ .../typegraph/tests/registry-ontology.test.ts | 36 ++ 31 files changed, 1989 insertions(+), 714 deletions(-) create mode 100644 .changeset/equivalence-is-subsumption.md delete mode 100644 packages/typegraph/src/graph-merge/closures.ts create mode 100644 packages/typegraph/test-d/ontology.test-d.ts create mode 100644 packages/typegraph/tests/backends/integration/ontology-equivalence.ts delete mode 100644 packages/typegraph/tests/graph-merge/closures.test.ts diff --git a/.changeset/equivalence-is-subsumption.md b/.changeset/equivalence-is-subsumption.md new file mode 100644 index 000000000..a3d95a1e8 --- /dev/null +++ b/.changeset/equivalence-is-subsumption.md @@ -0,0 +1,14 @@ +--- +"@nicia-ai/typegraph": minor +--- + +`equivalentTo` between two registered kinds now means MUTUAL SUBSUMPTION, with one closure behind every reading of "same class". `KindRegistry` folds each equivalence class into `subClassAncestors` / `subClassDescendants` before the transitive closure, so `isAssignableTo`, `isSubClassOf`, `expandSubClasses`, `getSubClassComponent` and disjointness propagation now agree by construction instead of answering three different ways: with `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, `includeSubClasses: true` on a `Company` alias returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { includeSubClasses: true })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair.

Target `"one"` with the default source `"many"` is many-to-one ownership: a source may point at many targets, each target may be pointed at once. This is the inverse-functional half that Gel's `exclusive` and TypeDB's two-sided `@card` already cover and that the source-only `cardinality` could not express. One decision layer owns both directions. `EdgeCardinalityAxisRef` is a discriminated `direction` plus `cardinality` pair (it makes `target:unique` unspellable), `edgeCardinalityAxisReferences` is the single fold every layer consults (probe, claim, batch overlay, fence audit, atomic-eligibility gates, schema tightening), and the claim spec table is keyed by direction. Source-side claim axis strings are byte-identical to before; the target axis reuses the reserved U+001E prefix that disjointness already uses, so existing `typegraph_edge_claims` rows keep fencing what they fenced and no migration is required. The two axes compose freely with every existing `cardinality` value including `unique`, and every public write path enforces both atomically: create, upsert, get-or-create, bulk writes, resurrection, validity-window reopening, validating import, and merge apply after endpoint canonicalization. Multi-axis claims are taken in `compareClaimTargets` order so two writers cannot invert their lock order, and a refused second claim rolls back inside the write frame. Two concurrent writers cannot both take the same target, verified with two real PostgreSQL sessions with history and revision tracking disabled. The bundled fused insert applies a single claim and returns `unsupported` for a two-axis plan before executing any SQL, so those writes take the portable path. The temporal populations are the existing ones read from the other end: `"one"` counts every non-deleted edge at the target including ended ones, `"oneActive"` counts only open-ended edges. Reopening a validity window re-probes only the active-only axes, since the row never released its `"one"` slot. Tightening either axis on a populated graph runs the same atomic data-check preflight an ontology tightening does, inside the schema-commit transaction, and refuses with `MigrationError` reason `"edge-cardinality-tightening-violated"` naming the violating endpoints. The serializer writes `targetCardinality` only when declared, so a graph that never uses the option keeps its schema hash. Runtime graph-extension documents may now declare both `cardinality` and `targetCardinality`. A trusted import refuses any edge cardinality declaration in either direction with reason `"cardinality_unsupported"`, closing a pre-existing hole where source-constrained graphs were written unfenced. The changeset carries a Breaking changes section: `countEdgesFrom` is replaced by the directional `countEdgesAtEndpoint`; `ClaimEdgeCardinalityParams` and the audit rows gain `direction`; `ManagedEdgeCreatePlan.cardinalityClaims` is plural; `CardinalityErrorDetails` gains required `direction`, `toKind`, `toId`; edge kind names containing U+001E are refused. Fusing both axes into one PostgreSQL statement is a named follow-up.

+--- + +An edge registration can declare `targetCardinality: "many" | "one" | "oneActive"`, bounding the edges that point AT one node independently of `cardinality`, which bounds the edges leaving one source. Target `"one"` with the default source `"many"` is many-to-one ownership: a source may point at many targets, each target may be pointed at once. The two axes compose freely — all twelve combinations with the existing `cardinality` values, `unique` included, are accepted and enforced together — and both are enforced atomically on every public write path: create, upsert, get-or-create, bulk writes, resurrection, validity-window reopening, validating import, and merge apply after endpoint canonicalization. Two concurrent writers cannot both take the same target, including on a default PostgreSQL store with history and revision tracking disabled. + +The target reservation is scoped to the graph, the edge kind, the target kind and the target id, and deliberately not to the source: two permitted source kinds contend for one target allowance. Equal ids under different target kinds, edge kinds or graphs never collide. The temporal populations are the existing ones read from the other end — `"one"` counts every non-deleted edge at the target, including edges with a validity end, while `"oneActive"` counts only those whose `validTo` is unset. Soft-deleted edges occupy no slot; a resurrection or a reopened window reacquires every applicable reservation; ending an edge frees an active-only slot and never frees a `"one"` slot. These are limits on edge count rather than on distinct neighbours, so a second distinct edge from the same source to a constrained target is refused too, while an idempotent operation returning the existing edge consumes nothing. + +`CardinalityError` stays the violation type and its details now name the `direction` and both endpoints. `verifyConstraintFences()` reports target-side violations in the existing `edgeCardinality` family. Schema serialization, hashing, introspection, runtime graph extensions and schema diffing preserve the declaration; a schema stored before this release loads as `"many"`. Tightening either axis on a populated graph now validates the existing rows inside the schema-commit transaction and refuses with a `MigrationError` naming the violating endpoints rather than publishing a constraint the data already breaks. + +Runtime graph-extension documents may now declare `cardinality` and `targetCardinality` on an edge. Previously both keys were rejected in strict mode and dropped otherwise, so an extension-authored edge kind was always unconstrained. + +### Breaking changes + +- `EdgeRegistration` gains `targetCardinality?`, and `EdgeIntrospection` gains a required `targetCardinality`. `SerializedEdgeDef` gains an optional `targetCardinality?`. Code that builds either object literal by hand adds the field where it needs one; everything produced through `defineGraph`, the serializer or `introspectSchema` is unaffected. The serializer omits `targetCardinality` for an edge kind that leaves it undeclared or declares the default `"many"` explicitly, so a graph that never uses this option serializes and hashes byte-identically to a document produced before this release — `ensureSchema` recognizes it as unchanged via the existing hash-equality check, with no serialize-and-diff walk and no extra cost on boot. A graph that does declare a non-default `targetCardinality` on at least one edge kind gets that value serialized and picks up a new schema hash, same as any other schema change. +- `GraphBackend.countEdgesFrom` is replaced by `countEdgesAtEndpoint`, whose params carry `endpoint: "from" | "to"` and the endpoint's identity as `endpointKind` / `endpointId` (not `kind` / `id` — that narrower shape would structurally satisfy `DeleteEdgeParams` / `HardDeleteEdgeParams` and silently conscript the read into the library's derived graph-entity write surface). A custom backend renames its implementation and reads the endpoint discriminant. +- `ClaimEdgeCardinalityParams` gains a required `direction: "source" | "target"` discriminant, and `EdgeCardinalityDeclaration` / `ContendedEdgeRow` gain the same. Source-side claim axis strings are byte-identical to before, so existing `typegraph_edge_claims` rows keep fencing what they fence today and no migration is required. +- `ManagedEdgeCreatePlan.cardinalityClaim` becomes `cardinalityClaims: readonly ClaimEdgeCardinalityParams[]`. A command port that applies the claim must apply every entry or return `unsupported` with the `"cardinalityClaim"` dimension before executing any SQL; the bundled fused insert applies a single claim and refuses a two-axis plan to the portable path. +- `CardinalityErrorDetails` gains required `direction`, `toKind` and `toId`. Existing `edgeKind` / `fromKind` / `fromId` / `cardinality` / `existingCount` are unchanged. +- A trusted import now refuses a graph declaring any edge cardinality, in either direction, with `TrustedImportError` reason `"cardinality_unsupported"`. That path maintains no claims, so it previously wrote source-side-constrained graphs unfenced. Use `importGraph`, or declare the kind unconstrained on both axes and enforce the limit in application code. +- A schema commit that newly declares a constrained `cardinality` or `targetCardinality` on an edge kind — including declaring one on a brand-new kind, since a stored schema with no entry for that kind reads as unconstrained (`many`) on both axes — now runs the same atomic data-check preflight an ontology tightening does, inside the schema-commit transaction. A backend that implements `commitSchemaVersion` but not `commitSchemaVersionWithPreflight` throws `ConfigurationError` code `EDGE_CARDINALITY_TIGHTENING_REQUIRES_ATOMIC_BACKEND` for such a commit, including one that only adds a new edge kind and touches no existing ontology relation. +- An edge kind name containing U+001E is refused at `defineGraph`, joining node kinds and unique constraint names.

merge apply deletes through the transaction port (#640) First slice of the composition contract's delete path: the pieces that need nothing from the composition relation itself and that the cascade will sit on. `NodeDeletePolicy` gains `consumedEdgeIds` and `cascadeComposition`. `enforceNodeDeleteBehavior` filters a node's connected edges by `consumedEdgeIds` before applying the kind's `onDelete` behavior, so an edge a caller has already accounted for is neither a `restrict` obstacle nor removed a second time. With the set empty, today's behavior is byte-identical, and the tests prove that by construction rather than by assertion. The fused-versus-portable node-delete route is now one owner, `nodeDeletePolicyRequiresPortablePath`, so a policy dimension the fused atomic delete cannot honor (`consumedEdgeIds`, or `enforceDeleteBehavior: false`) routes to the portable path instead of being silently ignored; a PGlite test pins the bypass on the root path where it is reachable. Merge apply's node delete is routed through a policy-carrying member on the transaction runtime port rather than through the collection facade, so a delete policy never leaks into the public collection API. The first version of that route bound to a freshly built store-scoped context and lost the transaction's buffered hook runner and attempt number; review caught it, and the route now binds to the same transaction's own hook context, with a test that fails when the routing is reverted. Merge apply passes `cascadeComposition: false` explicitly, so the later cascade lane cannot inherit an unstated default. No public API changes beyond the internal port; no changeset until the composition release lands. --- .../etc/typegraph-graph-merge.api.md | 15 ++ .../etc/typegraph-interchange.api.md | 15 ++ .../etc/typegraph-postgres-pglite.api.md | 15 ++ .../typegraph/etc/typegraph-profiler.api.md | 15 ++ .../typegraph/etc/typegraph-provenance.api.md | 15 ++ .../etc/typegraph-sqlite-local.api.md | 15 ++ packages/typegraph/etc/typegraph.api.md | 15 ++ packages/typegraph/scripts/api-report.ts | 41 ++-- packages/typegraph/src/graph-merge/merge.ts | 37 +++- .../src/graph-merge/typegraph-internal.ts | 3 + .../src/store/operations/node-operations.ts | 61 ++++-- .../store/operations/node-write-pipeline.ts | 83 +++++++- packages/typegraph/src/store/runtime-port.ts | 79 +++++++ packages/typegraph/src/store/store.ts | 34 ++- packages/typegraph/src/store/types.ts | 19 ++ .../tests/backends/integration-test-suite.ts | 2 +- .../tests/backends/integration/index.ts | 2 +- .../node-delete-policy-wiring.test.ts | 198 ++++++++++++++++++ .../node-delete-policy-consumed-edges.test.ts | 195 +++++++++++++++++ ...e-policy-root-atomic-bypass-pglite.test.ts | 146 +++++++++++++ packages/typegraph/vitest.pglite-project.ts | 1 + 21 files changed, 962 insertions(+), 44 deletions(-) create mode 100644 packages/typegraph/tests/graph-merge/node-delete-policy-wiring.test.ts create mode 100644 packages/typegraph/tests/node-delete-policy-consumed-edges.test.ts create mode 100644 packages/typegraph/tests/node-delete-policy-root-atomic-bypass-pglite.test.ts diff --git a/packages/typegraph/etc/typegraph-graph-merge.api.md b/packages/typegraph/etc/typegraph-graph-merge.api.md index 7fed09307..23e4dbbe9 100644 --- a/packages/typegraph/etc/typegraph-graph-merge.api.md +++ b/packages/typegraph/etc/typegraph-graph-merge.api.md @@ -4462,6 +4462,13 @@ type NodeCreateCommandResult = Readonly<{ // @public type NodeCurrentReads = Pick, (typeof CURRENT_ONLY_READ_NAMES)[number]>;

a `partOf` or `hasPart` without a realizing edge, or a `via` on any other meta-edge, is refused at registry build and at schema load with a `ConfigurationError` (`ONTOLOGY_COMPOSITION_VIA_REQUIRED`, `ONTOLOGY_COMPOSITION_VIA_FORBIDDEN`, `ONTOLOGY_COMPOSITION_PART_SIDE_FORBIDDEN`). Both relations were inert before, so nothing that worked stops working; a persisted document carrying the old triple fails on load and `getSchemaChanges` reports it before upgrade. `via` and `partSide` travel through every representation of an ontology relation (compile-time, named, serialized, extension document, introspection) and both canonical relation keys use a tuple encoding rather than a delimiter join, so a relation is identified by its full shape. The realizing edge may run in either orientation. Orientation is inferred from the declared pair against the edge's endpoints; when both orientations are admissible (a same-kind containment edge) the declaration must name `partSide`, and one edge kind declared in two orientations is refused. The single-whole fence sits on whichever side is the whole: `cardinality: "one" | "oneActive"` when the part is the edge's `from`, `targetCardinality: "one" | "oneActive"` when the part is its `to`; `"many"` on the whole side and `"unique"` are refused. A realizing edge must be composition-exact (every endpoint pair it admits is a declared composition pair), and every composition edge that can accept a given part kind must declare the same temporal population, so a part can never hold one `one` whole and one `oneActive` whole at once. `buildCompositionRelation` is the one traversal that builds and validates the relation; `KindRegistry` exposes it through `compositionRelation()` and derived readers (`isCompositionEdge`, `compositionPartSide`, `getCompositionEdge`, `compositionEdgeKindsUnder`/`Over`, `compositionPartKindsUnder`, `compositionWholeKindsOver`, `compositionPopulation`), which are subclass-aware. `EdgeEndpointKinds` becomes `EdgeKindFacts`, one entry type carrying endpoints and both cardinalities, built at one site per input shape. Removing a runtime kind now tracks a composition relation's `via` edge as a referent, so a realizing edge cannot be removed out from under its relation. This PR contains declaration, validation, and plumbing only. The composition claim axis, the delete cascade, `parts()`/`wholes()` navigation, and the composition changeset land in the following sub-lanes. --- .../docs/examples/document-management.md | 24 +- apps/docs/src/content/docs/ontology.md | 75 +- .../typegraph-adapters-drizzle-engine.api.md | 7 + ...ph-adapters-drizzle-postgres-pglite.api.md | 7 + ...typegraph-adapters-drizzle-postgres.api.md | 7 + ...raph-adapters-drizzle-sqlite-libsql.api.md | 7 + ...graph-adapters-drizzle-sqlite-local.api.md | 7 + .../typegraph-adapters-drizzle-sqlite.api.md | 7 + .../typegraph/etc/typegraph-backend.api.md | 7 + packages/typegraph/etc/typegraph-core.api.md | 7 + .../etc/typegraph-graph-extension.api.md | 7 +- .../etc/typegraph-graph-merge.api.md | 72 +- .../etc/typegraph-interchange.api.md | 70 +- .../etc/typegraph-postgres-pglite.api.md | 70 +- .../typegraph/etc/typegraph-profiler.api.md | 70 +- .../typegraph/etc/typegraph-provenance.api.md | 70 +- .../typegraph/etc/typegraph-schema.api.md | 68 +- .../etc/typegraph-sqlite-local.api.md | 70 +- packages/typegraph/etc/typegraph.api.md | 82 +- .../typegraph/examples/08-custom-ontology.ts | 34 +- packages/typegraph/scripts/api-report.ts | 76 +- .../typegraph/src/graph-extension/compiler.ts | 2 + .../typegraph/src/graph-extension/errors.ts | 3 + .../src/graph-extension/extension-types.ts | 5 + .../src/graph-extension/ontology-keys.ts | 17 +- .../typegraph/src/graph-extension/remove.ts | 41 +- .../src/graph-extension/validation.ts | 41 +- packages/typegraph/src/index.ts | 2 + .../typegraph/src/ontology/core-meta-edges.ts | 33 +- packages/typegraph/src/ontology/index.ts | 4 + packages/typegraph/src/ontology/types.ts | 5 + packages/typegraph/src/ontology/validation.ts | 128 ++- .../typegraph/src/registry/build-validated.ts | 71 +- packages/typegraph/src/registry/builders.ts | 16 +- .../src/registry/composition-relation.ts | 491 +++++++++++ .../src/registry/edge-endpoint-allowance.ts | 14 +- .../typegraph/src/registry/edge-kind-facts.ts | 24 + packages/typegraph/src/registry/index.ts | 2 +- .../typegraph/src/registry/kind-registry.ts | 249 ++++-- .../src/registry/validate-implies.ts | 36 +- .../src/registry/validate-inverse.ts | 8 +- packages/typegraph/src/schema/deserializer.ts | 30 +- .../typegraph/src/schema/ontology-change.ts | 52 +- packages/typegraph/src/schema/serializer.ts | 2 + packages/typegraph/src/schema/types.ts | 11 + packages/typegraph/src/store/claims/verify.ts | 4 +- packages/typegraph/src/store/introspect.ts | 9 + .../graph-extension-ontology-keys.test.ts | 87 ++ .../typegraph/tests/ontology-change.test.ts | 49 +- .../ontology-composition-declaration.test.ts | 828 ++++++++++++++++++ .../tests/ontology-hardening.test.ts | 12 +- .../property/schema-serialization.test.ts | 148 +++- .../typegraph/tests/registry-ontology.test.ts | 35 +- .../tests/schema-composition-load.test.ts | 228 +++++ .../typegraph/tests/store-introspect.test.ts | 46 +- .../tests/store-remove-kinds.test.ts | 110 ++- 56 files changed, 3325 insertions(+), 362 deletions(-) create mode 100644 packages/typegraph/src/registry/composition-relation.ts create mode 100644 packages/typegraph/src/registry/edge-kind-facts.ts create mode 100644 packages/typegraph/tests/graph-extension-ontology-keys.test.ts create mode 100644 packages/typegraph/tests/ontology-composition-declaration.test.ts create mode 100644 packages/typegraph/tests/schema-composition-load.test.ts diff --git a/apps/docs/src/content/docs/examples/document-management.md b/apps/docs/src/content/docs/examples/document-management.md index 6cbb6106d..c0b904246 100644 --- a/apps/docs/src/content/docs/examples/document-management.md +++ b/apps/docs/src/content/docs/examples/document-management.md @@ -22,8 +22,6 @@ import { embedding, searchable, subClassOf, - partOf, - hasPart, } from "@nicia-ai/typegraph"; // Base content type (abstract) @@ -118,7 +116,13 @@ const graph = defineGraph({ Permission: { type: Permission }, }, edges: { - contains: { type: contains, from: [Folder], to: [Folder, Document] }, + contains: { + type: contains, + from: [Folder], + to: [Folder, Document], + // A Folder or Document belongs to exactly one parent Folder. + targetCardinality: "one", + }, relatedTo: { type: relatedTo, from: [Document], to: [Document] }, hasPermission: { type: hasPermission, from: [User], to: [Content] }, createdBy: { type: createdBy, from: [Content], to: [User] }, @@ -128,9 +132,17 @@ const graph = defineGraph({ subClassOf(Folder, Content), subClassOf(Document, Content), - // Compositional relationships - partOf(Document, Folder), - hasPart(Folder, Document), + // `contains` is deliberately NOT declared as a `partOf`/`hasPart` + // composition relation.

The same contract is checked at registry build for whatever the type checker cannot see (extension-authored and persisted relations), through the `isStructuralSubtype` predicate that landed earlier, iterating the assignability closure rather than the declared relation list so `equivalentTo` and `sameAs` are checked in both directions and every transitive consequence is covered by one loop. Four error codes split the refusals by remedy (`not-subtype` versus `incomparable`, for `subClassOf` and for equivalence). Only the AFTER side of a schema diff is enforced, so an already-incoherent persisted document can still be repaired by a fix-forward migration; `getSchemaChanges` throws the same `ConfigurationError` as the dry run, and `requiresMigration` collapses it to `true` by design. A migration that only edits a subclassed kind's property schema now also reaches the check; previously the diff short-circuited before building a registry when no relation changed. With the contract in place, `from()`, `to()`, `fromDynamic()`, and `toDynamic()` default to `includeSubClasses: true` (the ruling recorded as Q3: TypeDB and Gel are polymorphic by default, and a supertype query that omits subtype rows is a partial answer once the schema says they are well-typed). Rows are typed with the parent's properties; the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect, decided by a non-recursive extract over the graph's ontology tuple, so a graph with no subsumption declarations sees no type churn. `queryDefaults.includeSubClasses` on `createStore` restores exact-kind behavior everywhere. Six internal builder sites pin `includeSubClasses: false` explicitly (`search()`'s candidate subquery and five collection paths, including `updateWhere`, which going polymorphic would be a data-corruption class rather than a read widening), and a test enumerates them. `search()`'s own `includeSubClasses` option stays opt-in as a documented asymmetry. `includeNarrower: true` on the same four methods expands a kind through the `broader`/`narrower` taxonomy relations with an untyped alias. The two expansions are mutually exclusive on one alias and refused rather than silently unioned; a narrower closure naming an unregistered kind, or on `to()` a kind the traversed edge does not admit, is refused too. One resolver owns the expansion axis for all four methods, and the query AST records the decision (`expansion: "exact" | "subClasses" | "narrower"`) instead of a boolean a consumer would re-derive. The C.1/C.2 agreement is pinned without a second comparison engine: a named projection of the type-visible schema fragment feeds the same `isStructuralSubtype`, a fast-check property asserts that structural subtyping implies type-level subtyping over generated schemas and tightening chains, and a fixture table cross-checks Zod pairs against whether `subClassOf(Child, Parent)` compiles. A known gap is disclosed rather than hidden: `z.set()`/`z.map()` fields project to a shape the predicate cannot distinguish, and the module documents the serializer fix that would close it. Docs lead with the instance-level taxonomy pattern (a concept kind, an `acyclic` `broader` edge, `.recursive()`) and present kind-level `broader`/`narrower` as the small-fixed-vocabulary case. The changeset carries Breaking changes and Upgrade notes, including the one-line `queryDefaults` opt-out and the `getSchemaChanges` pre-upgrade check. --- .changeset/typed-subsumption.md | 23 +

checked twice: at compile time, and at registry build for whatever the type checker cannot see. `subClassOf(child, parent)` becomes generic and requires that the child's schema output structurally

between two registered kinds check the same contract in both directions (D1's mutual-subsumption reading). A pair that fails is refused at compile time with a named `StructuralSubtypeMismatch` object naming the offending fields, and at registry build (live graphs, `evolve()`-authored extensions, and deserialized documents alike) with a `ConfigurationError` under one of four codes (`ONTOLOGY_SUBCLASS_NOT_STRUCTURAL_SUBTYPE`, `ONTOLOGY_SUBCLASS_SCHEMA_INCOMPARABLE`, `ONTOLOGY_EQUIVALENCE_NOT_STRUCTURAL_SUBTYPE`, `ONTOLOGY_EQUIVALENCE_SCHEMA_INCOMPARABLE`) naming the child, the parent, whether the pair was declared or reached transitively, and the full violation list. `getSchemaChanges` reports the same refusal before an upgrade, including when a migration only edits a property schema on a kind already party to an existing hierarchy — `requiresMigration` collapses it to `true` by design (least-privilege routing) rather than surfacing it; call `getSchemaChanges` directly for the detail. The new `isTypeLevelSubtype` (on the `/schema` entrypoint) is the runtime prediction of the compile-time check, useful for tooling that wants to know in advance whether a pair will compile. Known gap: the registry check compares projected JSON Schema, so a node kind containing a Zod construct `z.toJSONSchema` cannot convert (`z.set()`, `z.map()`, and others) is skipped rather than guaranteed — avoid those constructs on a kind that participates in `subClassOf`/`equivalentTo` for now. + +Now that the structural contract holds, `from()`/`to()`/`fromDynamic()`/`toDynamic()` default to `includeSubClasses: true`: a query against a supertype returns its subtype rows, typed with the parent's properties (the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect). `queryDefaults.includeSubClasses` on `createStore(...)` restores the previous exact-kind behavior everywhere in one place; `search()` and the collection APIs (`find`, `count`, `updateWhere`, `compareAndSet`) are unaffected and stay exact-kind. + +`from()`/`to()`/`fromDynamic()`/`toDynamic()` also accept `includeNarrower: true`, expanding a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf` — the alias type is untyped, since no schema relationship is claimed. `includeSubClasses` and `includeNarrower` are mutually exclusive on one alias, refused (`QUERY_ALIAS_EXPANSION_CONFLICT`) rather than silently unioned; an `includeNarrower` expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint is refused too (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). + +## Breaking changes + +- **`subClassOf`/`equivalentTo`/`sameAs` are now generic and carry a structural contract.** Code that annotates a relation's result as `OntologyRelation` still compiles unchanged; code declaring a pair whose child does not structurally extend the parent no longer compiles, and the identical pair is refused at registry build even for callers that bypass the compile-time check (an extension's raw `{ metaEdge: "subClassOf", from, to }` relation, or a persisted document). +- **Supertype queries now return subtype rows.** `from()`/`to()`/`fromDynamic()`/`toDynamic()` default to `includeSubClasses: true`. `search()` and the collection APIs are unchanged and stay exact-kind. +- **Alias types widen under the polymorphic axis.** For a kind that some other kind declares itself a subclass of, or that participates in a registered-kind `equivalentTo`/`sameAs`, the alias's `kind` is `string` and its `NodeId` brand widens, because the row may be a subtype.

Nothing from this PR is exported from the package root; the module is reached by path from tests and from the two follow-up PRs. Reconciliation (three-way assertion conflicts, identity-driven candidate pairing, merge-option policies) is a separate PR, and the public `IdentityFacade` surface, receipts field, archival interchange support and the changeset all land with the release PR after that. There is no changeset in this PR. Two relations carry the log: `typegraph_identity_transitions`, one append-only row per transition naming the affected class before and after, the cause, the assertion ids involved, an optional decision-provenance blob, and the recorded revision and instant it was written at; and `typegraph_identity_transition_retention`, one row per graph recording how far transitions have been pruned. Both join the existing `IdentityTableNames` / `SqlTableNames` / `SqlSchema` surfaces used for custom table naming, so `ensureIdentityTables` and the DDL generators provision all six identity relations together on first enablement. A base-schema release 3 (`identity-transition-log`) adds the corresponding adoption step to both dialects, so a pre-existing database self-heals the two new relations the next time it opens, whether or not any graph in it has identity enabled yet; before this, opening an already identity-enabled graph against an older physical schema, or enabling identity for the first time on a populated database, failed with a missing-table error the moment a fold tried to flush a note. Writing a transition note reuses the existing per-transaction recorded-capture session rather than growing a second lifecycle: the session gains `noteIdentityTransition` (buffered alongside the existing touch tracking, included in checkpoint/restore, sealed the same way after flush) and `withIdentityDecision` (an ambient, scoped decision that every note taken inside it inherits, living on the session rather than a backend-keyed map so it survives `deriveBackend`). The notes hang off the two functions that already own "the materialized class changed" — `mergeCurrentClasses` and `replaceAffectedClosure` — plus seven other call sites, covering all nine exhaustive causes a class's membership can move under: `assert` (an `assertSame` fusing classes), `retract` (a retraction possibly splitting one), `fold` and `restore` (a same-id create joining or resurrecting a class, distinguished by whether the creation is threaded as a resurrection rather than probed after the fact), `detach` (a soft or hard delete removing a member), `window-end` (a validity-window narrowing that changes coordinate-visible membership with no ledger write), `kind-drop` (a schema kind removal cascading through assertions and closure rows), `schema-transition` (a schema-commit-triggered closure rebuild re-labelling classes), and `reconcile` (a governed merge apply, always carrying decision provenance). A closure rebuild that rewrites derived state from unchanged truth is deliberately not a cause and writes no row. Replay (`identityReplay` / `identityTransitionsOf`, internal for this PR) walks a class's lineage to a fixed point over the transition log, collects the distinct recorded revisions the walk touches as boundaries, and reconstructs membership at each boundary exclusively through the existing `historicalIdentityReconstructionCtes` reader — never through the transition row's own class columns — reusing each boundary's `after` as the next boundary's `before` so the read cost is one reconstruction per boundary rather than two. It refuses with a typed `IdentityReplayError` when history capture is off, when the requested range needs more boundaries than the caller's limit (naming a resume point), or when the requested range is entirely below the retention watermark; a partially-truncated range instead returns a `truncatedBefore` marker on the result rather than silently under-reporting. `pruneIdentityTransitions` deletes transition rows strictly below a resolved revision and advances the per-graph retention watermark monotonically — a prune at an earlier revision than the current watermark is a no-op, never a rollback — and does not advance the graph's content revision, so pruning retained explanation does not make open branches stale the way an ordinary write would. `readTransitionRetentionDetails`'s `pruned_at` column is decoded through the identity module's one timestamp codec instead of a raw-string reader, matching a decode fix already needed for the log's own `recorded_at` / `valid_at` columns: an undecoded reader breaks on real PostgreSQL drivers that return `Date` values or non-ISO text once a graph has been pruned even once, a case SQLite and PGlite cannot reproduce because both already return canonical text. `ensureSchema` is split into a public wrapper and an internal `ensureSchemaInternal`, with the new `historyEnabled` flag moved onto an internal-only options type only `ensureSchemaInternal` accepts. This closes a path where a standalone caller of the public `ensureSchema` or `migrateSchema` entry points could otherwise bind a capture session and write recorded identity rows outside a `Store`. Enabling identity for the first time also needed its own preflight fix: the schema commit that performs first enablement runs against the constructor-supplied backend, before `StoreImplementation`'s constructor wraps it with the recorded-capture backend, so `identitySchemaCommitPreflight` found no capture session bound and silently dropped every `schema-transition` note even when history was requested. It now accepts an optional capture binding and, when supplied, binds a capture session directly to its own schema-commit transaction target, the same pattern the kind-removal preflight already used for its own schema commit. The fast-check exhaustiveness property test is the single most load-bearing test in this change: over randomized sequences of asserts, retractions, creates, deletes, restores and window-narrowings against a real backend, it asserts that a class's membership changed at a revision if and only if the transition log carries a row there, that replay's boundaries equal exactly the changed revisions, and that every step's before/after match a brute-force historical read; forcing the shared diff predicate to always return no rows breaks the property within a handful of generated cases, and developing the test caught two real defects, an unfiltered valid-time instant that hid every assertion-derived edge from reconstruction and a diff that silently dropped a shrinking class whose surviving member kept its old canonical label. The cross-backend merge/split/re-merge replay test proves the same contract end-to-end on both SQLite and PGlite: removing the `retract` note from the closure-repair call site makes the split boundary vanish and the post-retract membership assertion fails identically on both backends. The provisioning regression test reproduces both missing-table gaps directly — dropping the two new relations under an already-enabled graph, and dropping all six under a populated but not-yet-enabled one — and pins that simply reopening the store self-heals them. Public surface: `IdentityTableNames`, `SqlTableNames`, `ResolvedSqlTableNames` and the internal `SqlSchemaFields` contract gain `identityTransitions` / `identityTransitionRetention` entries, extending the existing custom-table-naming surface to the two new relations. `IdentityServiceContext` and `PlainNodeRef`, and the `identityContext()` accessor that returns the former, are new forgotten exports reachable from several package entry points; they are recorded in the forgotten-export debt ledger rather than intentionally published, and PR-3 is expected to retire them. `SchemaManagerOptions.historyEnabled` was considered for the public options bag and pulled back onto the internal-only type described above, so it carries no public surface change. ---

Sits on the composition relation owner (#641) and the delete-policy plumbing (#640). Deleting a composition whole cascades leaf-first through its live parts closure. `planCompositionCascade` walks the registry's composition relation from the whole through `compositionEdgeKindsUnder` its actual kind, in either realizing orientation, bounded by a visited set rather than a fixed depth, and drops members whose own node row is no longer live so the runtime cascade and merge's orphan checks see one correct closure. Each part then runs through its own node-delete pipeline inside the whole's transaction with the composition edge it arrived on in `consumedEdgeIds`, so per-part `onDelete` behavior on non-composition edges (restrict, cascade, disconnect) is honored exactly as a direct delete would honor it. The cascade takes the per-graph constraint fence once for the whole; `nodeDeleteNeedsConstraintFence` in `store/constraints.ts` is the one owner of that classification, mirroring the create/update split that already existed. Composition edges never count against a `restrict` delete on either end. A part declared `onDelete: "restrict"` can be deleted out of its whole, and an intermediate whole that is itself a restrict-kind part can be cascaded through, because the whole owns the containment edge rather than the part being obstructed by it. The restrict arm now also removes those edges through the same `deleteEdgesById` owner the cascade arm uses, closing a path where a cleared restrict delete left a live composition edge pointing at a tombstoned node. Reflexive composition is permitted at the kind level and nothing yet refuses the corresponding instance cycle when the realizing edges are written, so the closure walk detects a revisit deterministically and refuses with `CompositionCycleError` (`COMPOSITION_CYCLE_DETECTED`) naming the whole and the revisited node, instead of looping or silently truncating. The single-whole fence that prevents the cycle at write time is the next composition PR. `registry.isCompositionWhole(kind)` and `isCompositionPart(kind)` replace four inline spellings of "does this kind participate in composition" across the delete fence probe, the fused atomic-delete eligibility guard, and merge's orphan scan. The fused atomic node-delete program reports `unsupported` for a composition whole and the portable cascading path handles it. A branch that deletes a whole can conflict with a part attached to that whole on the target after the branch point. `planMerge` and `planMergeIncremental` scan the resolved plan against the target's current state and report every such finding in `MergePlanReview.compositionOrphans` (part, whole, realizing edge kind), resolving each member against its own immediate whole rather than the root. `applyMergePlan` re-runs the same check inside the apply transaction under the per-graph write lock and refuses with `MergeCompositionOrphanError` (`MERGE_COMPOSITION_ORPHAN`) when a concurrent attach raced the plan. Merge apply continues to delete with `cascadeComposition: false`: the plan is the authority over what apply deletes, and a cascade the reviewer did not see is never applied. The plan artifact gains the review field, so `MERGE_PLAN_FORMAT_VERSION` is now 2 and the artifact type and schema family are renamed `V2` to match; `parseMergePlanArtifact` reports a stored version-1 artifact as `unsupported-version`. `MergeCompositionOrphanErrorDetails` is removed in favor of the plan-time finding's own type, so the dry-run report and the apply-time refusal cannot diverge. Trusted import does not enforce composition and the constraint-fence audit reports it, as the interchange page now states. The limitations page documents the three behaviors that are easy to assume and are not what happens: resurrecting a soft-deleted whole restores the whole alone, ending a whole's validity window is not a cascade, and the cascade emits one operation-hook event for the whole. The provenance page flags retraction's undecided interaction with the cascade rather than claiming one. This PR carries the composition relation changeset for #641, #640 and this change together, including the Breaking section (`via` required on `partOf` / `hasPart`, whole-side cardinality required on the realizing edge, deleting a whole now deletes its parts, the plan artifact version bump). The cascade plan test fails when the leaf-first reversal is removed (members come back root-first), and the orphan apply test fails when the apply-time re-verification is made a no-op (the refusal degrades to a generic restrict conflict off the ordinary delete path instead of the typed orphan error). Each mutation was reverted and the suite re-run green. --- .changeset/composition-relation.md | 18 + apps/docs/src/content/docs/errors.md | 63 ++ apps/docs/src/content/docs/graph-merge.md | 26 + apps/docs/src/content/docs/interchange.md | 18 +- apps/docs/src/content/docs/limitations.md | 33 + .../typegraph/etc/typegraph-backend.api.md | 2 +- .../etc/typegraph-graph-merge.api.md | 30 +- .../etc/typegraph-interchange.api.md | 2 + .../etc/typegraph-postgres-pglite.api.md | 2 + .../typegraph/etc/typegraph-profiler.api.md | 2 + .../typegraph/etc/typegraph-provenance.api.md | 2 + .../typegraph/etc/typegraph-schema.api.md | 2 + .../etc/typegraph-sqlite-local.api.md | 2 + packages/typegraph/etc/typegraph.api.md | 19 + .../backend/capabilities/bundle-registry.ts | 5 +- packages/typegraph/src/errors/index.ts | 42 + .../src/graph-merge/durable-branch.ts | 4 +- .../src/graph-merge/durable-merge.ts | 4 +- packages/typegraph/src/graph-merge/errors.ts | 40 + packages/typegraph/src/graph-merge/index.ts | 6 +- packages/typegraph/src/graph-merge/merge.ts | 212 +++- .../src/graph-merge/plan-canonical.ts | 20 +- .../typegraph/src/graph-merge/plan-schema.ts | 64 +- .../typegraph/src/graph-merge/plan-wire.ts | 34 +- .../src/graph-merge/review-schema.ts | 6 +- .../src/graph-merge/typegraph-internal.ts | 6 + packages/typegraph/src/index.ts | 2 + .../src/interchange/trusted-import.ts | 4 +- packages/typegraph/src/provenance/index.ts | 11 + .../typegraph/src/registry/kind-registry.ts | 19 + packages/typegraph/src/store/constraints.ts | 29 + .../operations/atomic-mutation-program.ts | 25 + .../store/operations/composition-cascade.ts | 403 ++++++++ .../src/store/operations/node-operations.ts | 255 ++++- .../store/operations/node-write-pipeline.ts | 198 ++-- .../src/store/operations/write-session.ts | 26 +- packages/typegraph/src/store/types.ts | 7 + .../tests/bundle-member-access.test.ts | 13 +- .../tests/capability-bundle-totality.test.ts | 6 +- .../tests/composition-cascade-pglite.test.ts | 151 +++ .../tests/composition-cascade.test.ts | 967 ++++++++++++++++++ packages/typegraph/tests/errors.test.ts | 41 + .../graph-merge/composition-orphan.test.ts | 468 +++++++++ .../tests/graph-merge/merge-plan.test.ts | 11 +- .../tests/graph-merge/plan-wire.test.ts | 37 +- .../ontology-composition-declaration.test.ts | 12 + .../session-sidecar-completeness.test.ts | 39 + packages/typegraph/vitest.pglite-project.ts | 1 + 48 files changed, 3181 insertions(+), 208 deletions(-) create mode 100644 .changeset/composition-relation.md create mode 100644 packages/typegraph/src/store/operations/composition-cascade.ts create mode 100644 packages/typegraph/tests/composition-cascade-pglite.test.ts create mode 100644 packages/typegraph/tests/composition-cascade.test.ts create mode 100644 packages/typegraph/tests/graph-merge/composition-orphan.test.ts diff --git a/.changeset/composition-relation.md b/.changeset/composition-relation.md new file mode 100644 index 000000000..9032ccade --- /dev/null +++ b/.changeset/composition-relation.md @@ -0,0 +1,18 @@ +--- +"@nicia-ai/typegraph": minor +--- + +`partOf` and `hasPart` are now a real [composition](https://typegraph.dev/ontology#composition) relation, realized by an edge kind that stores the containment. `partOf(part, whole, { via, partSide? })` and its mirror `hasPart(whole, part, { via, partSide? })` name that edge with `via`; orientation is inferred from the declared pair against the edge's endpoints, and when both orientations are admissible (a same-kind containment edge) the declaration names `partSide: "from" | "to"`.

Depends on the composition relation owner (#641) and the delete-policy cascade (#640) already on this branch. `QueryBuilder` gains `parts()` and `wholes()`, declared-structure builder sugar over the existing recursive `Traversal` AST for a declared composition relation (`partOf` / `hasPart`). Instead of naming the realizing edge kind and its direction by hand, `parts("alias", { from?, maxHops?, depth?, path? })` derives the edge kind(s) and direction(s) from the registry's composition relation and recurses to the full transitive closure by default (`maxHops: 1` gives the direct level only). `wholes()` is the mirror and returns the ancestor chain. Direction is derived per realizing edge kind rather than fixed. A `part -> whole` edge is followed reversed and a `whole -> part` edge is followed in its own direction. A relation realized by both orientations across levels compiles to one traversal step whose direct and inverse edge-kind sets union through the existing `inverseEdgeKinds` mechanism, so a mixed relation costs nothing extra to declare and the common uniform-orientation case pays nothing extra to compile. The result alias is untyped (`DynamicNodeType` / `DynamicEdgeType`, reached via `.field(name)`): the parts/wholes closure under a kind is registry data that may span several node kinds with different schemas. Calling `parts()` / `wholes()` on a kind that declares no composition parts or wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows. `expand` is not accepted on either step. `SubgraphOptions` gains `composition?: boolean`: it closes the selected root over the composition edge kinds under its actual kind before the existing projection runs, in addition to whatever `edges` already lists. This is the whole-plus-parts export unit. The option is set-level: a root kind declaring no composition parts contributes nothing and the read still runs, while a graph declaring no composition relation at all refuses with `ConfigurationError`. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()` / `toDynamic()` for an explicit, already-resolved set of target node kinds. `parts()` / `wholes()` are its first caller. Direction and target-kind resolution live in one owner (`partitionCompositionEdgeKindsByDirection` in `registry/composition-relation.ts`), so the query builder and `subgraph()` cannot drift from the registry's composition facts. A recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set compiled its recursive term as two branches, each self-joining the recursive CTE, unioned with `UNION ALL`. PostgreSQL refuses a recursive CTE whose self-reference appears more than once in its recursive term, while SQLite accepted it, so the defect only surfaced against a real PostgreSQL engine once mixed-orientation composition exercised the path. Both orientations are now normalized into one directed-edges relation, computed once before recursion starts, which also carries the recorded-time columns and `graph_id` so recorded reads and multi-graph databases stay correct through it. The ontology guide documents `parts()` / `wholes()`, the subgraph composition export, and the containment tiering (composition, aggregation, mereology) the roadmap ratified. Cross-relation guarantees that later composition PRs deliver (single-whole fence, existence: required) are marked forthcoming rather than claimed. --- .changeset/composition-navigation.md | 13 + apps/docs/src/content/docs/core-concepts.md | 11 + apps/docs/src/content/docs/ontology.md | 52 ++ .../src/content/docs/queries/recursive.md | 119 ++++ apps/docs/src/content/docs/queries/source.md | 3 + .../docs/src/content/docs/queries/traverse.md | 9 + apps/docs/src/content/docs/schemas-stores.md | 32 + .../etc/typegraph-graph-merge.api.md | 19 + .../etc/typegraph-interchange.api.md | 19 + .../etc/typegraph-postgres-pglite.api.md | 19 + .../typegraph/etc/typegraph-profiler.api.md | 19 + .../typegraph/etc/typegraph-provenance.api.md | 19 + .../etc/typegraph-sqlite-local.api.md | 19 + packages/typegraph/etc/typegraph.api.md | 19 + packages/typegraph/scripts/api-report.ts | 28 +- packages/typegraph/src/index.ts | 1 + packages/typegraph/src/query/builder.ts | 1 + packages/typegraph/src/query/builder/index.ts | 6 +- .../src/query/builder/query-builder.ts | 391 +++++++++++- .../src/query/builder/traversal-builder.ts | 72 +++ .../src/query/compiler/passes/temporal.ts | 17 + .../typegraph/src/query/compiler/recursive.ts | 224 +++++-- .../typegraph/src/query/compiler/temporal.ts | 14 + packages/typegraph/src/query/index.ts | 1 + .../src/registry/composition-relation.ts | 64 ++ packages/typegraph/src/store/recursive-cte.ts | 214 ++++++- packages/typegraph/src/store/store.ts | 1 + packages/typegraph/src/store/subgraph.ts | 282 +++++++-- .../tests/backends/integration-test-suite.ts | 2 + .../integration/composition-navigation.ts | 575 ++++++++++++++++++ .../tests/backends/integration/index.ts | 1 + .../ontology-composition-declaration.test.ts | 71 +++ .../typegraph/tests/query-dynamic.test.ts | 96 ++- .../tests/recursive-compiler.test.ts | 124 +++- .../recursive-traversal-inventory.test.ts | 15 +- 35 files changed, 2457 insertions(+), 115 deletions(-) create mode 100644 .changeset/composition-navigation.md create mode 100644 packages/typegraph/tests/backends/integration/composition-navigation.ts diff --git a/.changeset/composition-navigation.md b/.changeset/composition-navigation.md new file mode 100644 index 000000000..b4417721f --- /dev/null +++ b/.changeset/composition-navigation.md @@ -0,0 +1,13 @@ +--- +"@nicia-ai/typegraph": minor +--- + +`QueryBuilder` gains `parts()` and `wholes()`, declared-structure builder sugar over the existing recursive `Traversal` AST for a declared [composition](https://typegraph.dev/ontology#composition) relation (`partOf` / `hasPart`).

Every closure and write-path decision for a meta-edge — which ones are transitive, symmetric, have an inverse, participate in a data probe on a tightening change — is hardcoded per literal meta-edge name in `collectOntologyRelations` (`src/registry/kind-registry.ts`) and `classifyKnownRelationSeverity` (`src/schema/ontology-change.ts`); nothing ever read these fields off a `MetaEdge` object. The custom factory only ever let a caller attach serialized-introspection metadata the registry could not act on. Free-form, type-level vocabulary now has a real home: `defineGraph({ annotations })`, persisted and introspectable exactly like the removed factory's output, minus the illusion of built-in reasoning. `examples/08-custom-ontology.ts` is rewritten to demonstrate `annotations` in place of the custom `metaEdge()` section it used to carry. **What's removed** (all `### Breaking` in the changeset): - `metaEdge()` and `MetaEdgeOptions` (`@nicia-ai/typegraph`, `@nicia-ai/typegraph/core`). - The public `InferenceType` union (`@nicia-ai/typegraph`, `@nicia-ai/typegraph/backend`). - `MetaEdgeProperties.{transitive,symmetric,reflexive,inverse,inference}` — `MetaEdgeProperties` now carries only `description`. - The deprecated `sameAs()`/`differentFrom()` relation factories and the `core.sameAs`/`core.differentFrom` members. The meta-edge NAMES are still recognized wherever they can still appear (a persisted document, a declarative graph extension) — only the code-level constructors are gone. - `SerializedMetaEdge` narrows to `{ name, description }`. - `OntologyChange["entity"]` narrows from `"metaEdge" | "relation"` to `"relation"` — see "classifier cleanup" below. **The persisted-document load rule.** A document written before this release still loads. `serializedSchemaZod` stays `.loose()` on each `metaEdges` entry, so the five now-internal fields parse through unread rather than rejecting the document. A persisted `sameAs` relation keeps folding into the same equivalence closure as `equivalentTo` (`collectOntologyRelations` switches on the meta-edge NAME, which is untouched); the classifier's verdict on opening a store whose code has since migrated `sameAs(A,B)` to `equivalentTo(A,B)` is warning-only (relation removed + relation added, never breaking) and auto-migrates on open. A persisted `differentFrom` relation was always inert (decorative, never enforced); the classifier's verdict on its removal is `safe` and auto-migrates on open. Both are exercised by load-bearing tests in `tests/meta-edge-removal-migration.test.ts`, including the end-to-end path through `ensureSchema` against a real backend — not just the diff math in isolation. **Classifier cleanup (the resolved blocker).** `classifyOntologyChanges` used to diff the serialized `metaEdges` catalog as a second, independent classification arm, unconditionally `breaking` on any name leaving it. That catalog is derived 1:1 from `relations` by the serializer — a meta-edge name disappearing from it is always a consequence of its last relation being removed, an event the relation-level diff already classifies through its severity table. The catalog arm disagreed with that table for every `safe`/`warning` relation removal, `sameAs` and `differentFrom` included, which is what first blocked this removal (an unconditional `breaking` for a removal this lane's own migration rule says should auto-migrate). Dropped as a redundant, contradicting second owner of one decision; `OntologyChange` loses its `"metaEdge"` entity arm as a result, and every consumer of that arm (tests, docs tables) was re-audited — none remain outside this repo's own now-updated tests. **Docs.** One consolidated migration-guide section — `apps/docs/src/content/docs/schema-evolution.md` §"Upgrading past the removed `sameAs`/`differentFrom`/`metaEdge()` APIs" — covers all three removals: what to delete, that `annotations` is the replacement for free-form type-level semantics, and the exact persisted-document load/ auto-migrate behavior for each case, including the one case where opening a store under this release rewrites a persisted document on its own (a relation naming a caller's removed custom `metaEdge()`, which can no longer serialize at all). **Extension surface.** Declarative graph extensions still refuse a custom meta-edge name — `ALL_META_EDGE_NAMES` stays closed, and nothing in this change reopens it (there was never a "custom name" escape hatch to begin with; `metaEdge()`, the only thing that ever produced a non-core name, is gone).

Every read-only caller built on `computeSchemaDiff` inherits this: `loadAndVerifyGraph` (and so `createVerifiedStore` / `assertSchemaCurrent`) and `getSchemaChanges()` now also throw `ConfigurationError` for the same unclassifiable-ontology documents. `requiresMigration()` is the one exception — as the least-privilege routing predicate, it treats "cannot classify" the same as "needs migration" and returns `true` instead of throwing, so a document only the privileged path can interpret still routes there rather than crashing the check meant to route it. ### Breaking changes @@ -12,5 +12,5 @@ Ontology changes are now classified by what they do to existing data, and a tigh ### Upgrade notes - Adding or removing `inverseOf`/`implies` now requires an explicit `migrateSchema()` even against clean data — `ensureSchema()`'s auto-migrate branch refuses these with `MigrationError` `reason: "breaking-change"`. -- `subClassOf`/`equivalentTo`/`sameAs`/`disjointWith` additions are probed against live rows inside the commit transaction and refused with `MigrationError` `reason: "ontology-tightening-violated"` when the data already violates the tightened ontology; inspect `details.violations` (same shape as `store.verifyConstraintFences()`) to find and resolve the offending rows before retrying. +- `subClassOf`/`equivalentTo`/`disjointWith` additions are probed against live rows inside the commit transaction and refused with `MigrationError` `reason: "ontology-tightening-violated"` when the data already violates the tightened ontology; inspect `details.violations` (same shape as `store.verifyConstraintFences()`) to find and resolve the offending rows before retrying. - `store.verifyConstraintFences()` now also reports the `edgeEndpointAssignability` family, so it may surface pre-existing violations on a database that has never run this check before — treat a non-empty result the same way as the existing families (inspect, resolve, or track as known debt). diff --git a/.changeset/remove-custom-meta-edge.md b/.changeset/remove-custom-meta-edge.md new file mode 100644 index 000000000..a4de5c7f6 --- /dev/null +++ b/.changeset/remove-custom-meta-edge.md @@ -0,0 +1,18 @@ +--- +"@nicia-ai/typegraph": minor +--- + +The public custom `metaEdge()` factory, the public `InferenceType` union, and the deprecated `sameAs`/`differentFrom` type-level factories are removed. None of them ever drove runtime behavior beyond serialized introspection metadata: every closure and write-path decision for a meta-edge is hardcoded per literal name in `collectOntologyRelations` (`src/registry/kind-registry.ts`) and `classifyKnownRelationSeverity` (`src/schema/ontology-change.ts`), never read off a `MetaEdge`'s properties. Free-form, type-level vocabulary the library has no built-in reasoning for now belongs in `defineGraph({ annotations })` — see [Type-Level Annotations](https://typegraph.dev/ontology#type-level-annotations) and `examples/08-custom-ontology.ts` for a complete example. Replace `sameAs(A, B)` with `equivalentTo(A, B)` (behaviorally identical in every release `sameAs` shipped in); delete `differentFrom(A, B)` calls (it was decorative and never enforced) or, for real cross-kind instance identity, use the TypeGraph Identity Profile (`identity: { sameIdAcrossKinds: "fold" }` and `store.identity`). The serialized schema document drops `metaEdges[*].transitive`/`symmetric`/`reflexive`/`inverse`/`inference` on the next write that a real ontology change triggers — `SerializedMetaEdge` now carries only `name`/`description` — and the deserializer's Zod validator no longer requires these fields, so a document written before this release keeps loading and its extra fields are ignored. Upgrading the library alone does not rewrite a stored document: `ensureSchema` only writes a new version when it detects a semantic change, so a graph whose ontology is otherwise untouched keeps its pre-removal document (and pays the slower parse-and-diff path on every boot, instead of the schema-hash fast path) until its next real schema change lands. A persisted `sameAs` relation keeps folding into the equivalence closure exactly like `equivalentTo`; a persisted `differentFrom` relation keeps being inert. A relation naming a custom `metaEdge()` you called before this release is different: since the factory that declared it is gone, your upgraded graph can no longer serialize that relation at all, so the first commit `ensureSchema` makes after upgrading auto-migrates it away — classified `safe` (a custom name reaches no closure or write-path decision) and dropped from the rewritten document with no opt-in. Copy anything you need from that relation into `annotations` **before** upgrading; see the migration guide linked below. The `OntologyChange` union's `entity` field narrows from `"metaEdge" | "relation"` to `"relation"`: the removed `"metaEdge"` arm was a second, contradicting classifier for a state the relation-level diff already classified correctly (a meta-edge name leaving the serialized `metaEdges` catalog is always a consequence of its last relation being removed or added, never an independent event, since the catalog is derived 1:1 from `relations`). Graph extensions continue to refuse a `metaEdge` name outside the closed core set — nothing in this change reopens that. + +**Rolling deploys and rollback.** The new serializer output is a one-way door: a document written by a `@nicia-ai/typegraph` release with this change (only after that document's next real schema commit — see above) cannot be parsed by an earlier release, because the pre-change `serializedSchemaZod` required `transitive`/`symmetric`/`reflexive`/`inference` on every `ontology.metaEdges` entry. Upgrade every reader of a shared database (every application instance, in a mixed-version fleet) to this release or later before any of them commits a schema change, and do not roll back to a pre-change release once one has — an older instance's `parseSerializedSchema` throws on the rewritten document instead of degrading. + +See [Upgrading past the removed `sameAs`/`differentFrom`/`metaEdge()` APIs](https://typegraph.dev/schema-evolution#upgrading-past-the-removed-sameasdifferentfrommetaedge-apis) for the complete migration guide. + +### Breaking changes + +- Removed: `metaEdge()` and `MetaEdgeOptions` (`@nicia-ai/typegraph`, `@nicia-ai/typegraph/core`). +- Removed: the public `InferenceType` union (`@nicia-ai/typegraph`, `@nicia-ai/typegraph/backend`). +- Removed: `MetaEdgeProperties.transitive`, `.symmetric`, `.reflexive`, `.inverse`, and `.inference` — `MetaEdgeProperties` now carries only `description`. +- Removed: the deprecated `sameAs()` and `differentFrom()` relation factories (`@nicia-ai/typegraph`), and the matching `core.sameAs` / `core.differentFrom` members of the exported `core` object.

Every write path that can put an edge into that relation — `create`, `bulkCreate`, upsert and `getOrCreateByEndpoints`, resurrection into the live population, validating import, and merge apply — is refused with the new `EdgeAcyclicityError` when the new edge's `to` endpoint already reaches its `from` endpoint; a self-loop is a cycle of length one and is refused by the same rule. `EdgeRegistration` gains `acyclic?: boolean`, deliberately a boolean rather than a mode string: the population question (which edges count) is settled once, store-wide, and is not a per-declaration knob in v1. `acyclic` is orthogonal to `cardinality`/`targetCardinality`, `matchIdentity`, `endpointExistence`, and `onDelete`, so `cardinality: "many", acyclic: true` — a dependency graph — is the common case and must still take the write fence even though its cardinality does not. Every place that used to answer "is this edge kind in an acyclic relation" by re-deriving `registration.acyclic === true` inline now calls one owner, `edgeKindIsInAcyclicRelation`/`acyclicEdgeKinds` in the new `src/store/acyclicity.ts`, and `standaloneAcyclicRelation` is the one constructor for a D.2 singleton relation — six call sites across edge-operations, the fused-eligibility gates, import, trusted-import, and the tightening preflight had drifted into separate copies of that check before this consolidation. `acyclicEdgeRelations` is memoized per `GraphDef` since the write-path probe calls it once per proposed edge in a batch. Serialization emits `acyclic` only when true, so a graph with no acyclic edge keeps a byte-identical schema hash; a defaulted parse would have re-materialized the key on every re-serialization. `AcyclicEdgeRelation` members carry orientation, `{ edgeKind, reversed: boolean }`, rather than a bare edge-kind list: a later composition relation mixes part→whole and whole→part realizing edges and must be checked as one directed relation, which a plain list cannot express. A standalone `acyclic: true` registration is the `reversed: false` special case, and the oriented seed/recursive-term forms this requires had zero test coverage until this branch added a mixed-orientation fixture and compiled-SQL pins for both seed shapes. `EdgeIntrospection.acyclic` is now a required `boolean` (`false` when not declared), and a runtime-authored graph-extension edge may declare `acyclic` alongside the `cardinality`/`targetCardinality` surface. The check is one predicate, `assertEdgeRelationsAcyclic`, asking whether `from` lies in the reflexive-transitive closure of `to` — order-insensitive with respect to the proposed rows, so probe-then-insert (single writes) and insert-then-probe (batches, merge apply) call the same function with the same meaning. It is a recursive reachability walk with no depth bound: `MAX_EXPLICIT_RECURSIVE_DEPTH` does not apply, so a cycle of any length is found, and the walk uses `UNION` rather than `UNION ALL` between the anchor and the recursive term so an unbounded recursion still terminates on a finite graph without path tracking. A property test checks 200 random DAGs plus a random candidate edge against an in-memory DFS oracle, and is the one load-bearing case that catches a wrong join direction or an off-by-one reflexive seed: inverting the recursive term's join-direction columns made it fail after three runs on the minimal shrunk two-node counterexample. A second load-bearing case builds ~2^30 distinct paths through a stacked-diamond lattice; switching the same statement from `UNION` to `UNION ALL` made that case hang past two minutes instead of completing in seconds, which is the proof that set semantics rather than path tracking is what makes an unbounded search actually bounded in practice. The builder introduces no new dialect seam: it consults the single existing `forceRecursiveWorktableOuterJoinOrder` capability and adds no `DialectAdapter` member and no dialect literal, so the dialect-literal inventory and its exemption list stay untouched. An engine that cuts a statement short — a statement timeout, a resource-exhaustion code — raises the new `EdgeAcyclicityIndeterminateError` rather than being read as "no cycle"; deleting the recognizer's initial capability check made both the write-path probe resolve `undefined` and the audit reader resolve an empty (falsely clean) result instead of rejecting, which is exactly the failure mode this guards against. The probe and the write it guards commit under the same per-graph write fence that already fences edge cardinality and node disjointness (`edgeWriteNeedsConstraintFence` now takes the whole registration rather than a bare cardinality, so the `cardinality: "many", acyclic: true` case still fences), backed as `lockOnly` since a cycle spans a whole reachable subgraph rather than a tuple a claim row could key on. A PostgreSQL session at `repeatable read` takes its transaction snapshot at the fence-acquisition statement, before that statement blocks, so the loser of a race would otherwise probe a pre-winner snapshot and commit a cycle; this is the identical hazard match-key convergence already guards, so the fix extracts one shared predicate, `observesPostFenceCommits(isolation)`, that both the convergence check and the new `EDGE_ACYCLICITY_REQUIRES_FRESH_SNAPSHOT` refusal consult, reading the isolation fact off the coordination token minted by the fence acquisition itself rather than from a requested option. A backend with no transactions refuses the write with `CONSTRAINT_WRITE_FENCE_UNSUPPORTED` and `details.constraint: "edgeAcyclicity"` instead of enforcing the rule only when nothing races. A real two-connection PostgreSQL test proves the fence: reverting the acyclic arm's fence reason to `undefined` turned a deterministic single-winner race into two nondeterministic commits and a wrong row count; a further PostgreSQL-only case drives a 10^5-edge chain and a one-millisecond statement timeout to force a genuine, not simulated, mid-probe cutoff and asserts `EdgeAcyclicityIndeterminateError` with nothing written. Adding `acyclic: true` to a populated edge kind is classified as a tightening (`entity: "edgeRegistration"`, a new `edgeAcyclicity` probe kind) and consumes the ontology classifier's existing data-validated tightening machinery rather than a separate code path; dropping `acyclic` classifies as safe with no probe. The schema-commit preflight runs the added probe's edge kinds through the same relation reader the write path and the audit share, never through the non-recursive constraint-fence port, and folds any violations into the same `MigrationError` `ontology-tightening-violated` refusal every other tightening uses. Reproducing the exact defect this closes — reverting the new arm's severity to `safe` with no probe — let a store with a pre-existing cycle migrate cleanly and carry an axiom its data contradicted, which is the load-bearing failure the test for this arm records. Validating import takes the per-graph write lock per chunk transaction only when the graph declares an acyclic edge kind (`graphOwesLockOnlyFence`, threaded as the existing constraint-probe mechanism rather than new lock-acquisition code), and refuses the whole import up front on a backend with no transactions. An acyclic kind's rows cannot join the validating import's batched slice flush, because the in-batch cardinality overlay intercepts specific read calls rather than a recursive statement it could see through; they instead join the existing sequential write-as-you-go fallback, where each row's probe runs inside the same savepoint-guarded attempt as its insert, so a cycle rolls back to the savepoint and reports as that row's own error while the rest of the chunk commits. Deleting the probe call on that row's create leg let all three edges of a proposed cycle commit instead of one being refused, which is the load-bearing check for the per-row behavior. `trustedImportGraphStream` refuses up front, `reason: "acyclicity_unsupported"`, for any acyclic edge kind: it validates nothing by contract and holds one transaction for the whole stream, so there is no per-row point to probe at. Merge apply was confirmed, not assumed, to need no acyclicity code of its own: it writes every edge through the store's own collection API, which already routes through the paths this change fences. A dedicated post-apply check was written, proven redundant by deleting it and watching the existing merge test still pass byte-identically, and removed rather than kept as untested defensive code. `store.verifyConstraintFences()` gains an `edgeAcyclicity` family reporting live edges already on a cycle. `ConstraintFenceViolation` is now a four-member union whose `target` is present only on the two claim-backed families, since acyclicity reserves no claim row a target could name; the final sort is replaced accordingly. The family runs the same relation reader as the write path directly against the backend rather than through the row-shape port the other, non-recursive families use, which would otherwise create a second implementation of "is there a cycle." The audit refuses rather than reporting an empty result when it cannot run — a backend with no recursive traversal support, or a cut-short statement — so a diagnostic never fabricates "clean." A cycle formed entirely from a merge plan's own proposed writes — three branch edges closing a cycle with nothing live yet — was invisible to a probe that could only join ancestry against live edges. The reachability builder's recursive term is refactored into a non-recursive candidates source (live edges reoriented, unioned with the proposed seed itself) joined once by the actual recursive step, because both PostgreSQL and SQLite refuse a recursive term that references the recursive relation more than once, so the live-edge and seed hops fold into one joined source rather than two recursive branches. This yields a lock-free, non-throwing preview, `readProposedEdgeAcyclicityViolations`, built on the same probe the write path and the audit reader already share. The merge planner's `resolveMerge` runs `assertResolvedPlanEdgesAcyclic` immediately after the internal plan is built — the same point the existing one-id-one-truth check runs its own plan-time validation — over the plan's merged edges resolved to their final endpoints, so a purely-in-plan cycle is caught before any write. A violation is the new `AcyclicityMergeConflictError` (`GRAPH_MERGE_ACYCLICITY_CONFLICT`), naming the relation and every offending edge, and every entry point that funnels through `resolveMerge` — a one-shot merge, a plan-then-apply review, and both incremental forms — inherits the check identically. Removing the seed-hop branch and re-running the fixture showed the plan resolving cleanly while the subsequent apply still refused through the unchanged apply-time write path, confirming the new check is what moves the refusal earlier rather than duplicating it. Apply-time re-verification is otherwise unchanged: a cycle that only appears from a write racing the plan preview, which holds no per-graph lock, still surfaces as `MergeConstraintConflictError` wrapping `EdgeAcyclicityError`. - `ConstraintFenceViolation` gains an `edgeAcyclicity` member alongside the existing `edgeEndpointAssignability` member without a claim `target`. Code that reads `violation.target` unconditionally must narrow on `violation.family` first. - `EdgeIntrospection.acyclic` is now a required `boolean` field (`false` for every edge kind that does not declare `acyclic: true`). - A merge whose resolved plan would close a cycle now fails with the new `AcyclicityMergeConflictError` at plan time rather than `MergeConstraintConflictError` at apply time. Code that specifically catches `MergeConstraintConflictError` (or matches on `cause.name === "EdgeAcyclicityError"`) to detect this case must also handle `AcyclicityMergeConflictError`; the apply-time shape still occurs for a cycle that only appears from a write racing the plan. - Adding `acyclic: true` to a populated edge kind is probed against live rows inside the commit transaction and refused with `MigrationError` `reason: "ontology-tightening-violated"` when a cycle already exists; inspect `details.violations` (same shape as `store.verifyConstraintFences()`) to find and resolve the offending rows before retrying. - A backend without transaction support cannot enforce acyclicity at all; writes to an acyclic edge kind are refused with `CONSTRAINT_WRITE_FENCE_UNSUPPORTED` rather than silently skipping the check. - Graph extensions may declare `acyclic` on a runtime-authored edge, alongside `cardinality`/`targetCardinality`. Fixed before the bench ran: acyclic insert p95 within 3× the `cardinality: "one"` p95 at 1e5 edges on the forest shape on both engines, and 8-writer PostgreSQL aggregate throughput at least 70% of the `cardinality: "one"` run. Failing either would require designing a maintained ancestor set before this ships. Measured on this branch after the probe's recursive step was changed to join the edges table directly (see below), single-writer insert latency, warm-up 1, 7 samples, median / p95, both engines with fresh planner statistics after seeding. Hardware: an 8-core laptop under concurrent load, so absolute numbers are indicative and the ratios are what the criteria read. | shape, 10^5 edges | SQLite `cardinality: "one"` | SQLite `acyclic: true` | PostgreSQL `cardinality: "one"` | PostgreSQL `acyclic: true` | | --- | --- | --- | --- | --- | | forest (the criterion shape) | 0.2 / 0.3 ms | 0.2 / 0.2 ms | 4.1 / 6.0 ms | 3.8 / 8.6 ms | | chain-append | 0.4 / 1.0 ms | 0.1 / 0.3 ms | 2.6 / 2.8 ms | 7.3 / 14.3 ms | | chain-prepend (walks the whole chain) | 0.3 / 0.5 ms | 220.5 / 229.1 ms | 2.8 / 3.1 ms | 467.9 / 475.4 ms | Forest p95 ratio: 0.7× on SQLite, 1.4× on PostgreSQL, both inside the 3× criterion. Chain-prepend is the documented worst case: the new edge points at the head, so the exhaustive walk visits every edge of the chain at roughly 2 µs (SQLite) to 5 µs (PostgreSQL) per hop; it is linear in the reachable set, not in the relation. The PostgreSQL chain-append row was measured while autovacuum was processing the 10^5 rows the seed had just written and its p95 is noise from that (the 10^4 row is 2.2 ms against a 2.6 ms baseline); it is reported as measured rather than re-run. PostgreSQL contention, W real connections appending to one shared 10^5-edge relation for 30 s each: | writers | `cardinality: "one"` throughput / p99 | `acyclic: true` throughput / p99 | | --- | --- | --- | | 2 | 390/s, 13.5 ms | 529/s, 13.1 ms | | 4 | 391/s, 59.3 ms | 361/s, 40.1 ms | | 8 | 412/s, 119.7 ms | 487/s, 70.3 ms | | 16 | 692/s, 153.3 ms | 654/s, 136.1 ms | 8-writer acyclic throughput is 118% of the `cardinality: "one"` run against a 70% criterion. Both fences serialize on the same per-graph advisory lock, so the probe adds nothing to the contended path beyond its own sub-millisecond seek. Both engines' plans were read back from the actual probe statement: SQLite seeks `typegraph_edges_from_idx` per hop; PostgreSQL seeks `typegraph_edges_cardinality_idx` (the same leading columns plus `kind`) per hop. The first version of the plan-time seed hop folded the relation's live edges and the plan's proposed rows into one compound `candidates` CTE that the recursive term joined. SQLite cannot flatten a compound subquery whose outer query is a join, so it materialized the entire relation on every probe and every acyclic insert became linear in the relation (forest p95 was 23× the baseline at 10^4 edges). The seed hop is only needed where the proposed rows are not yet in the table, which after an audit of every caller is exactly one place: the merge plan-time preview. `AcyclicityProbeSeed` therefore distinguishes `proposed` rows (already visible to the probing transaction, or a single row, which every write path satisfies) from `planned` rows (the merge preview), and only the latter pays the compound shape, once per plan. A relation with reversed members compiles to one join with an OR of two index-seekable arms rather than a second compound. Plan-shape tests on both engines capture the real probe statement and assert the per-hop index seek and the absence of a materialized relation; reverting to the compound shape fails them. Two follow-ups surfaced by the benchmark and filed separately: the fused stale-claim release DELETE plans as a whole-graph nested-loop anti-join under stale statistics (#647), and the atomic edge-claim batch statements scale super-linearly in chunk size on PostgreSQL (#648). Neither is in this change's code; the benchmark seeds fenced kinds one create at a time until #648 lands. --- .changeset/edge-acyclicity.md | 82 ++ apps/docs/src/content/docs/backend-setup.md | 11 +-

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the composition claim: `partOf`/`hasPart` edges now enforce that a part holds exactly one whole across every declared composition relation, the same way the existing edge-cardinality claim enforces target cardinality. The invariant is backed by one reserved axis on `typegraph_edge_claims` (`CompositionClaimScope`), not a new relation or statement shape, so it needs an interactive transaction the same way any other declared-cardinality write does and is identical on both dialects. A `partOf`/`hasPart` edge create, `bulkCreate`, upsert, `getOrCreateByEndpoints`, or resurrection into the live population that would give a part a second live whole is refused with the new `CompositionError`, naming the part, the rejected whole, the realizing edge kind, and (where the caller already read it) the incumbent edge id. Validating import (`importGraph`/`importGraphStream`) raises the same error per row, inside the row's own savepoint, so the rest of an import batch still commits. Trusted import — which writes no claim rows at all — refuses a target graph declaring any composition pair up front with a distinct `composition_unsupported` reason, alongside its existing `acyclicity_unsupported` reason; the two are independent because a composition edge's "exactly one whole" invariant is carried entirely by the reserved claim axis, not by the edge's own declared `cardinality`. An ontology change that newly declares `partOf`/`hasPart` between two kinds already holding data is tightened the same way `disjointWith` and `subClassOf` additions are: `store.verifyConstraintFences()` and `MigrationError`'s `"ontology-tightening-violated"` reason both gain a `family: "composition"` violation shape, reported when a part already holds two live wholes or the newly proposed composition relation contains a cycle. The consolidated `edgeKindIsInAcyclicRelation` / `acyclicEdgeRelations` family (D.2) now takes the graph's `KindRegistry` so a composition pair's realizing edges can fold into the answer as one directed, potentially mixed-orientation relation — reusing D.2's existing oriented-member representation rather than adding a second acyclicity code path. Every consumer of the widened contract was re-audited (table below); the two with a real behavior change (the atomic edge-batch fused command, and import's batched-slice deferral) were already the load-bearing tests' target. Composition is a common, high-value ontology relation (a document's sections, an order's line items, a project's tasks) and "a part has exactly one whole" is exactly the kind of invariant this library already enforces for ordinary edge cardinality — leaving it unenforced would push every consumer toward hand-rolled application-level checks that the store's own write paths could race past. Routing it through the existing claim-axis machinery (rather than a bespoke composition table) keeps the write, import, merge, and tightening-preflight paths uniform: composition is "one more claim family", not a parallel subsystem. | # | Call site | Disposition | | --- | --- | --- | | 1 | `store/claims/verify.ts` — `verifyConstraintFences` | Threads `context.registry`; unchanged consumption. |

Candidate pairing gained an identity-driven source: nodes an existing identity assertion already relates as `"same"` become merge candidates even without a matching constraint key, and an always-on separation veto (built on the existing `isSeparated`/`bulkIsSeparated` owner) refuses to merge nodes the graph has already proven distinct, regardless of what any assertion claims. The reconciliation options live in one nested bag, `MergeOptions.identity: IdentityReconciliationOptions`, with three sub-options (`pairing`, `onAssertionConflict`, `onProvenanceConflict`) folded into the existing `MERGE_OPTION_DEFAULTS` machinery as its one owner. Every accepted option is either honored or refused with a typed error naming the state it can't handle — no option is silently dropped. Two sub-options that would only ever have one legal value in this release (`onEdgeConflict`, `onUniquenessConflict`) are left out of the type entirely rather than shipped as decorative knobs: an option whose only accepted value is its own default is dead surface. Today's behaviors — `repoint` for an identity-paired edge collision, and the existing constraint-violation refusal for a uniqueness collision — remain the only behaviors. They're tracked for a later release once a plan-rebuild-after-repoint mechanism and a plan-time constraint-key probe through the store's own constraint lookup (rather than a second, merge-planner-local computation of the same keys) are both in place. Resolved and unresolved outcomes both render on the merge artifacts: `identityReconciliations` and `identityConflicts` appear presence-preservingly on `MergePlan`, `MergeReport`, and `MergePlanReview`, so an old plan without identity activity still revalidates as `compatible` under the unchanged `MERGE_PLAN_FORMAT_VERSION` of 2. The governing merge decision now threads through to the identity ledger: `applyMergePlan` builds the decision provenance and passes it through `applyIdentityChangesForContext`'s new `decision` parameter, which wraps the capture session's decision scope — so a transition note written during a merge apply carries the same decision identity the merge itself recorded, rather than a second, independently-derived one. **Why.** Today, two branches that each independently assert or retract the same identity relationship fail a merge outright on the first inline check that notices, with no way to express "prefer the branch that asserted" or "prefer the branch that retracted" short of hand-editing the plan. The classifier and options bag turn that into a policy decision the caller states up front, with the previous throw-always behavior preserved as the default. --- - **One predicate, one owner.** `compareIdentitySurvivors` and `identityAssertionSemanticKey` live only in `identity-three-way.ts`; `merge-identity.ts` re-imports, never re-spells. The separation veto calls `isSeparated`/`bulkIsSeparated` (the established one owner) rather than re-deriving class-lifted difference. `classifyIdentityPair` is the single classifier absorbing what were three inline arbitrations. - **Accepted or refused, never ignored.** `pairing`, `onAssertionConflict`, `onProvenanceConflict` are each threaded to a write path or refused with a typed error. `onEdgeConflict`/`onUniquenessConflict` — the two options that could only ever refuse — were removed from the type entirely rather than shipped as knobs with one legal value (ruling G2-4). - **A fused command is not evidence its dimensions ran.** No new `unsupported` command arm introduced; identity DML does not run through fused mutation programs. - **Runtime evidence bound to the resource that earned it.** Decision provenance flows through `applyIdentityChangesForContext`'s explicit `decision` parameter, wrapping the capture session's `withIdentityDecision` scope; `applyMergePlan` is the one caller that builds and threads it. - **A changed contract re-audits its consumers.** `planIdentityChanges`'s widened return (classify-then-resolve, plus `reconciliations`/`unresolved`) was checked against its one call site in `merge.ts` and the existing identity-merge/identity-reconciliation suites, all green in this pass's full-suite run. `applyIdentityChangesForContext`'s added `decision` parameter was checked against its `store.ts` and identity/service call sites. - **Backends derived, never copied.** No new backend object constructed; `identity-pairing.ts`/`identity-three-way.ts` read through existing runtime-port accessors. - **`*Backend` naming.** No new `*Backend`-suffixed identifier denoting a members fragment; `applyIdentityMergeAtTarget` is a method, not a backend object. - **Rebase discipline.** `src/graph-merge/merge.ts`'s composition-orphan check, seed-hop acyclicity check, and (newly, post this rebase) the plan-time `assertResolvedPlanEdgesAcyclic` check and the composition-claim logic are all intact post-rebase — confirmed present in `merge.ts`; the identity work is additive alongside them, not a replacement. ruling G2-1) Exported from `src/graph-merge/index.ts` (and reachable from the package barrel where noted): - `IdentityReconciliationOptions` — the one nested options bag on `MergeOptions.identity` / `NormalizedMergeOptions.identity`, folded into `MERGE_OPTION_DEFAULTS` via `IDENTITY_OPTION_DEFAULTS`. Ships with `pairing`, `onAssertionConflict`, `onProvenanceConflict`. - `IdentityAssertionConflictPolicy`, `IdentityAssertionConflictReason` — the policy union and classification-table reasons from `identity-three-way.ts`. - `IdentityUnresolvedConflict` — now two arms, `assertion` and `separation` (a `provenance` arm was removed in review since `onProvenanceConflict` has no resolving disposition that could ever produce it; a `uniqueness` arm is deferred with the option, see below). - `IdentityReconciliation` — the report/plan-artifact record of a resolved three-way pick (`identityReconciliations` on `MergePlan`/`MergeReport`). - The `IdentityMergeConflictError`-family error classes carrying the widened conflict reasons and typed `details`. - `IdentityDecisionProvenance` (re-exported from PR-1's `src/identity/transition-log.ts` surface), now also on the `StoreRuntime` port (`applyIdentityMergeAtTarget`'s parameter) — the source of the +1 forgotten-export debt on the five narrow entrypoints that structurally project `StoreRuntime` without re-exporting identity types themselves. - `MERGE_PLAN_FORMAT_VERSION` stays `2` (not bumped); the new `identityReconciliations`/`identityConflicts` fields are added presence-preservingly, and old version-2 artifacts still revalidate as `compatible`. No new facade beyond this — no `store.identity.replay`/`transitionsOf`, no receipts field, no archival interchange, no changeset. Those remain PR-3. `identity.onEdgeConflict` and `identity.onUniquenessConflict` do **not** ship in PR-2. Both are absent from `IdentityReconciliationOptions` rather than present as knobs whose only accepted value is the current default — an option that can only refuse is dead surface. Today's default behaviors (`repoint` for an identity-paired edge collision; the existing constraint-violation refusal for a uniqueness collision) remain the only behaviors. The full obstacle writeup (the missing fifth `IdentityUnresolvedConflict` arm and the plan-rebuild-after-repoint requirement for edge conflicts; the second-owner-of-constraint-keys problem for uniqueness) is recorded in the design note's §10 "Deferred to a later release" section and, as a standalone GitHub-issue-ready body, in `lane-G2-deferred-issue.md` in this scratchpad directory (not filed as an issue — that's left to the lead). --- .../etc/typegraph-graph-merge.api.md | 169 ++- .../etc/typegraph-interchange.api.md | 12 +- .../etc/typegraph-postgres-pglite.api.md | 12 +- .../typegraph/etc/typegraph-profiler.api.md | 12 +- .../typegraph/etc/typegraph-provenance.api.md | 12 +- .../etc/typegraph-sqlite-local.api.md | 12 +- packages/typegraph/etc/typegraph.api.md | 12 +- packages/typegraph/scripts/api-report.ts | 41 +- .../src/graph-merge/apply-callbacks.ts | 14 + packages/typegraph/src/graph-merge/errors.ts | 29 +- .../typegraph/src/graph-merge/evidence.ts | 26 +- .../src/graph-merge/identity-decision.ts | 105 ++ .../src/graph-merge/identity-pairing.ts | 279 ++++ .../src/graph-merge/identity-three-way.ts | 1155 +++++++++++++++++ packages/typegraph/src/graph-merge/index.ts | 21 +- .../src/graph-merge/merge-identity.ts | 333 ++--- packages/typegraph/src/graph-merge/merge.ts | 838 +++++++++++- packages/typegraph/src/graph-merge/options.ts | 90 ++ .../typegraph/src/graph-merge/plan-schema.ts | 105 +- packages/typegraph/src/graph-merge/sources.ts | 152 +++ .../src/graph-merge/typegraph-internal.ts | 15 + packages/typegraph/src/graph-merge/types.ts | 162 ++- packages/typegraph/src/identity/index.ts | 1 + packages/typegraph/src/identity/separation.ts | 241 +++- packages/typegraph/src/index.ts | 4 + packages/typegraph/src/store/runtime-port.ts | 8 + packages/typegraph/src/store/store.ts | 12 +- .../tests/graph-merge/commit.test.ts | 2 + .../identity-commit-closure.test.ts | 4 + .../graph-merge/identity-options.test.ts | 315 +++++ .../graph-merge/identity-pairing.test.ts | 898 +++++++++++++ .../identity-reconciliation.test.ts | 348 +++++ .../graph-merge/identity-three-way.test.ts | 717 ++++++++++ .../node-delete-policy-wiring.test.ts | 2 + .../identity-transition-log-ratchet.test.ts | 20 + 35 files changed, 5809 insertions(+), 369 deletions(-) create mode 100644 packages/typegraph/src/graph-merge/identity-decision.ts create mode 100644 packages/typegraph/src/graph-merge/identity-pairing.ts create mode 100644 packages/typegraph/src/graph-merge/identity-three-way.ts create mode 100644 packages/typegraph/tests/graph-merge/identity-options.test.ts create mode 100644 packages/typegraph/tests/graph-merge/identity-pairing.test.ts create mode 100644 packages/typegraph/tests/graph-merge/identity-reconciliation.test.ts create mode 100644 packages/typegraph/tests/graph-merge/identity-three-way.test.ts diff --git a/packages/typegraph/etc/typegraph-graph-merge.api.md b/packages/typegraph/etc/typegraph-graph-merge.api.md index ed458956d..4d1461e81 100644 --- a/packages/typegraph/etc/typegraph-graph-merge.api.md +++ b/packages/typegraph/etc/typegraph-graph-merge.api.md @@ -539,7 +539,7 @@ export type CandidateDiagnostic = Readonly<{ reason?: "noComparableValues";

Depends on the composition relation (#641), cascade (#645), navigation (#646) and claim (#654) already on this branch. `partOf` / `hasPart` gain `existence?: "optional" | "required"` (default `"optional"`, so every declaration written before this option keeps its semantics): `"required"` says a part of that kind can never exist without a live whole. `KindRegistry.compositionExistence(kind)` is the one reader every write path consults; two declarations disagreeing on `existence` for the same part kind refuse at registry build with `ONTOLOGY_COMPOSITION_EXISTENCE_MIXED` (R4 gives a part one whole across every relation, so "must this part have one" is a property of the part kind, not of a pair). `existence` is emitted only when `"required"` — an explicit `"optional"` serializes byte-identically to omitting it, so an untouched graph's schema hash is unchanged. `NodeCollection.create`'s options are extracted into `NodeCreateOptions`, `bulkCreate`'s per-item options and `NodeGetOrCreateByConstraintOptions` gain `partOf?: { kind: string; id: string }`: the whole a part is attached to, in the SAME write plan as the node — a lost composition claim, a dead or missing whole, or an undeclared pair aborts the node create too, so no orphan row survives a failed attach. `partOf` naming an undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`); a required-existence kind created with no `partOf` refuses with the new `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written. `partOf` is honored as a convenience on an optional-existence pair too, in the same one write. `getOrCreateByConstraint`/`bulkGetOrCreateByConstraint` apply `partOf` on the `"created"` and `"resurrected"` branches (resurrection restores the whole alone) and refuse it on `"found"`/`"updated"` with `CompositionExistenceError` (`situation: "existing"`, naming the node's current whole when it has a live one) rather than silently dropping a stated whole. Every fused/read-free node-create and edge-delete program declines a required-existence kind (or any input carrying `partOf`), so a required-existence bulk create or delete always takes the portable, fully-validated path. Ending, soft-deleting, or hard-deleting a required-existence part's composition edge while the part is LIVE is refused with `CompositionExistenceError` (`situation: "detach"`); a part that is already retired is not orphaned by losing its edge, so detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts exactly as before — `existence: "required"` governs bare creation and detachment, not whole deletion. Validating import tracks every required-existence part it creates and, once the whole payload's node and edge sets are both known, accepts one already attached in the same batch or already live on the target and reports a per-row error (removing the orphaned node row in the same transaction) for anything still unattached — the rest of the import commits. Trusted import already refuses every declared composition pair regardless of `existence` (`composition_unsupported`), so there is no separate reason code for the required case. `store.verifyConstraintFences()` gains a `compositionExistence` family, reporting any LIVE required-existence part with no live whole; a schema commit newly declaring `existence: "required"` on an already-populated pair runs the same check as a tightening preflight and refuses a dirty graph rather than silently admitting orphans. Graph merge's composition-orphan check gains a second arm for `existence: "required"`: alongside the existing check (a live part left behind when the merge deletes its whole node), it now also catches a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all, reported at plan time (`MergePlanCompositionOrphan.cause: "unattached"`) and refused at apply with the same `MergeCompositionOrphanError`. One residual gap remains: a composition edge silently dropped by canonicalization's own endpoint-deleted repointing, which issues no write for this (or any) per-write guard to see — run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](/limitations#composition-existence-existence-required). - `CompositionPair` (internal to the registry; not part of the public entrypoint) gains a required `existence` field — anything constructing one directly, such as a test fixture, must add it. - `ConstraintFenceViolation`'s union gains the `compositionExistence` member; an exhaustive `switch (violation.family)` outside the library needs a new arm. - `MergePlanCompositionOrphan` gains a required `cause: "deleted" | "unattached"` field and its `whole` becomes optional (absent for `cause: "unattached"`, which has no whole to name); a consumer constructing or exhaustively matching this shape needs updating. The create path is one write plan: `resolveCompositionCreate` is the single owner of "what whole does this create owe" (four arms: required without `partOf` refuses, `partOf` naming an undeclared pair refuses, otherwise the work), and the composition edge is inserted through the same `edgeInsertWork` / `edgeInsertClaims` pipeline an ordinary edge create uses, so the composition claim, endpoint existence and acyclicity are all applied once by their existing owners. The detach refusal lives at the edge work-assembly sites, not inside the pipeline entries, because `EdgeWriteContext` deliberately resolves no schema; it is gated on the part being live, and the whole-delete cascade is exempt by construction since it removes edges through its own sweep. Every fused node-create and edge-delete program declines a required-existence input (or any input carrying `partOf`); each of those four eligibility gates has a direct unit test that fails when its guard clause is deleted, since the store's ordinary create and delete paths never reach the resolvers for a composition write and an integration case alone could not catch a removed guard. The backend-layer invariant belt the plan sketched is not added: it would need the kind registry threaded into a layer that is deliberately registry-agnostic. The audit and the tightening preflight share one portable scan of live required parts without a live whole rather than a new per-dialect backend member, because both run at diagnostic or schema-commit time, never on a write's hot path. The merge arm catches the required-part cases a merge's own writes can produce and reports them at plan time with `cause: "unattached"`; the one case it cannot see is an edge canonicalization drops through endpoint-deleted repointing, which issues no write for a per-write guard to observe. That case is documented on the limitations page with `store.verifyConstraintFences()` as the check to run after such a merge. Serialization emits `existence` only when `"required"`, so untouched graphs keep their schema hash (the same rule `targetCardinality` and `acyclic` follow).

charset=UTF-8 Content-Transfer-Encoding: 8bit Identity reconciliation graduates from internal machinery to a public, documented surface: replay, transition history, and the merge-time reconciliation policy bag are now part of the package contract. - `store.identity.replay(ref)` and `store.identity.transitionsOf(ref)` land on both the store and transaction identity facades — every call site that can write also needs to explain what it wrote. `IdentityReadFacade` (the coordinate-pinned `store.asOf(...).identity` lens) deliberately does not get these methods: a pinned lens answers for one coordinate, while replay and transition history are queries across every recorded coordinate, and exposing them there would silently ignore the pin. - `pruneIdentityTransitions`, `IdentityReplayError`, `IdentityTransition`, `IdentityTransitionCause`, `IdentityReplayStep`, `IdentityReplay`, `IdentityReplayOptions`, `IDENTITY_REPLAY_DEFAULT_LIMIT`, and `IDENTITY_REPLAY_MAX_LIMIT` are exported from the package barrel — the types a caller needs to consume replay output and to run retention. - `IdentityWriteSummary` gains `transitions: number` beside (never inside) `total`: a transition-log note is an annotation of a write `total` already counts, not a fourth kind of write. The same field lands on the frozen disabled-graph summary so a graph with identity turned off still reports a well-typed zero rather than an absent field. A history-enabled `transactionWithReceipt` now reports `writes.identity.transitions`, sourced from the recorded-capture flush's own per-graph note count rather than a second read of the notes buffer — the receipt can't disagree with what was actually written. Archival-mode export now carries a `transitions` section plus a retention watermark, bumping the interchange format to `3.0`; state export and branch cloning carry nothing, since neither claims to be a durable backup of identity history. Restoring an archive validates the transitions section's shape only — it never re-derives class membership — and marks every restored row as such so `replay` never pairs a restored transition with a fabricated before/after. When the destination has no identity transitions of its own yet, restore also sets its own watermark to the highest restored revision + 1, so `replay` reports the pre-restore range as truncated instead of claiming a complete history it cannot reconstruct. `pruneIdentityTransitions` stays an explicit, operator-invoked action; it never advances the content revision on its own. Restoring an archival document whose source ever retained or pruned identity transitions now requires the destination to be opened with `history: true` — `importGraph`/`importGraphStream` refuse up front with `IDENTITY_REPLAY_REQUIRES_HISTORY` rather than silently writing a document with no way to carry the transitions it names. `onEdgeConflict` and `onUniquenessConflict` are not part of this release — deferred, tracked in #657. The shipped reconciliation policy bag covers `pairing`, `onAssertionConflict`, and `onProvenanceConflict` only; defaults preserve current merge behavior exactly except for one narrow, deliberate change (earliest-staged `validTo` wins on a same-assertion end-date race, deterministic and branch-order-independent). The transition-log relation gains a nullable `restored_at` column through base-schema release 4 (`identity-transitions-restored-at`), adopted on both dialects on the next open (`ADD COLUMN IF NOT EXISTS` on PostgreSQL; a `PRAGMA table_info` check on SQLite). Restored rows keep their source coordinates for `transitionsOf`, `replay` never uses a restored row as a boundary, and the retention watermark is never moved by a restore, so a graph's own pre-restore history replays byte-identically before and after an unrelated restore. --- .changeset/identity-reconciliation.md | 67 ++ apps/docs/src/content/docs/backend-setup.md | 2 +- apps/docs/src/content/docs/errors.md | 63 +- apps/docs/src/content/docs/graph-merge.md | 83 ++- apps/docs/src/content/docs/identity.md | 186 +++++- apps/docs/src/content/docs/interchange.md | 92 ++- .../src/content/docs/schema-management.md | 5 + apps/docs/src/content/docs/schemas-stores.md | 18 + .../typegraph-adapters-drizzle-engine.api.md | 37 ++ ...ph-adapters-drizzle-postgres-pglite.api.md | 17 + ...typegraph-adapters-drizzle-postgres.api.md | 34 + ...raph-adapters-drizzle-sqlite-libsql.api.md | 19 + ...graph-adapters-drizzle-sqlite-local.api.md | 19 + .../typegraph-adapters-drizzle-sqlite.api.md | 38 ++ .../etc/typegraph-graph-merge.api.md | 111 ++++ .../etc/typegraph-interchange.api.md | 254 ++++++- .../etc/typegraph-postgres-pglite.api.md | 73 ++ .../typegraph/etc/typegraph-profiler.api.md | 73 ++ .../typegraph/etc/typegraph-provenance.api.md | 73 ++ .../etc/typegraph-sqlite-local.api.md | 73 ++ packages/typegraph/etc/typegraph.api.md | 114 ++++ packages/typegraph/scripts/api-report.ts | 87 ++- .../src/backend/drizzle/base-schema.ts | 10 + packages/typegraph/src/backend/drizzle/ddl.ts | 37 ++ .../engine/members/base-schema-members.ts | 20 + .../typegraph/src/backend/drizzle/postgres.ts | 19 + .../src/backend/drizzle/schema/postgres.ts | 8 + .../src/backend/drizzle/schema/sqlite.ts | 8 + .../typegraph/src/backend/drizzle/sqlite.ts | 41 ++ .../typegraph/src/backend/sqlite/local.ts | 70 +- .../src/graph-merge/candidate-write-set.ts | 3 +- packages/typegraph/src/identity/index.ts | 16 +- packages/typegraph/src/identity/replay.ts | 36 +- .../typegraph/src/identity/service-facade.ts | 9 + .../src/identity/service-interchange-write.ts | 165 ++++- packages/typegraph/src/identity/service.ts | 10 + .../typegraph/src/identity/transition-log.ts | 301 ++++++++- packages/typegraph/src/identity/types.ts | 60 ++ packages/typegraph/src/index.ts | 15 + packages/typegraph/src/interchange/export.ts | 160 ++++- packages/typegraph/src/interchange/import.ts | 176 ++++- packages/typegraph/src/interchange/index.ts | 4 + .../src/interchange/trusted-import.ts | 10 + packages/typegraph/src/interchange/types.ts | 115 +++- .../typegraph/src/store/collection-surface.ts | 12 + .../typegraph/src/store/recorded-capture.ts | 28 +- packages/typegraph/src/store/runtime-port.ts | 50 +- packages/typegraph/src/store/store.ts | 104 ++- .../src/store/transaction-receipt.ts | 33 +- packages/typegraph/src/utils/sql-errors.ts | 14 + .../engine-profile-parity.test.ts.snap | 72 ++ .../backends/integration/identity-replay.ts | 11 +- .../tests/backends/integration/identity.ts | 90 ++- .../tests/base-schema-adoption.test.ts | 88 +++ .../tests/identity-import-hardening.test.ts | 629 ++++++++++++++++++ .../typegraph/tests/identity-replay.test.ts | 81 ++- .../identity-transition-log-ratchet.test.ts | 26 +- .../tests/identity-transition-log.test.ts | 6 +- packages/typegraph/tests/interchange.test.ts | 32 +- .../identity-replay-exhaustive.test.ts | 2 +- .../tests/transaction-receipt.test.ts | 40 ++ .../typegraph/tests/trusted-import.test.ts | 38 ++ 62 files changed, 4060 insertions(+), 127 deletions(-) create mode 100644 .changeset/identity-reconciliation.md diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md new file mode 100644 index 000000000..8617064c5 --- /dev/null +++ b/.changeset/identity-reconciliation.md @@ -0,0 +1,67 @@ +--- +"@nicia-ai/typegraph": minor +--- + +Identity-aware Reconciliation.

The integration branch's declared breaking changes (147 unique declaration/member/kind breaks across the entrypoints, 961 findings) are now recorded there, one entry per entrypoint as the checker matches, each with the specific reason, the changeset section that declares it, and the introducing PR as its issue. Every entry maps to a `### Breaking` bullet in one of the release's changesets; four intended contract changes the changesets had not listed (the identity transition-log relations and their table-name overrides) get their bullet in the identity reconciliation changeset. No type an external consumer authors gained a required member without a declaration. The runtime port's one optional-member shim comment now says the shim was a one-off rather than the port's rule, since the port is an `@internal` symbol-keyed contract no consumer can name and its new members are recorded in the ledger instead of shimmed. Dispositions per declaration are in the session record; the checker exits 0 on this branch and the ledger audit reports no stale entry. --- .changeset/identity-reconciliation.md | 7 + .../typegraph/etc/api-surface-exceptions.json | 7691 ++++++++++++++++- packages/typegraph/src/store/runtime-port.ts | 12 +- 3 files changed, 7704 insertions(+), 6 deletions(-) diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 8617064c5..399dac054 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -56,6 +56,13 @@ transaction's flush wrote, an annotation of the assertion/retraction writes ### Breaking changes +- The identity transition log adds two relations, `typegraph_identity_transitions` + and `typegraph_identity_transition_retention`, which `ensureSchema` creates on + an identity-enabled graph. `createSqlSchema` accepts `identityTransitions` and + `identityTransitionRetention` as optional overrides alongside the existing + table names; a deployment whose migration tooling enumerates TypeGraph's + relations, or whose database role has restricted DDL, must account for both + before upgrading. - Restoring an archival export (`identityMode: "archival"`) whose source graph retains identity transitions or has ever pruned them now requires the restore target to be opened with `history: true`. `importGraph` and diff --git a/packages/typegraph/etc/api-surface-exceptions.json b/packages/typegraph/etc/api-surface-exceptions.json index fe51488c7..4cb39d1b4 100644 --- a/packages/typegraph/etc/api-surface-exceptions.json +++ b/packages/typegraph/etc/api-surface-exceptions.json @@ -1 +1,7690 @@ -[] +[ + { + "entrypoint": "typegraph-adapters-drizzle-postgres-pglite.api.md", + "declaration": "ClaimEdgeCardinalityParams", + "member": "cardinality", + "kind": "member-removed", + "reason": "`cardinality` was not dropped: it moved, together with the new `direction: \"source\" | \"target\"` discriminant, into the shared `EdgeCardinalityAxisRef` member of an intersection, and the type still carries it.

Discovery now walks the whole log to a fixed point and only the returned transitions are filtered to the window. The walk itself keyset-pages through every matching row rather than refusing at a fixed ceiling, so a lineage that has grown past one read never needs a destructive prune to become readable. **History pages instead of refusing.** `limit` caps the number of boundaries one page returns, and a capped page hands back `nextFrom`, a cursor to pass as the next call's `fromRecorded`. The `IDENTITY_REPLAY_LIMIT_EXCEEDED` refusal, whose recovery hint advanced past boundaries the caller never received, is removed. A non-positive `limit` is refused up front. `nextFrom` is scoped to the transition log and documented as never being a valid `asOfRecorded` input. **Restored transitions say so.** A transition an archival restore brought in carries `restored.at`, the destination's wall clock at restore time, so an audit view can tell an imported explanation from a locally replayable event. The field is a wall clock rather than a `RecordedInstant` because a restore records history without reliving it: it never advances the destination's recorded-revision counter, so there is no revision on the destination's own axis to pair with the timestamp. `transitionsOf` returns restored rows with the field set; `replay` never uses one as a boundary, and the retention watermark stays the only revision-shaped signal a restore leaves. **Reconciliation scope stated up front.** The graph-merge guide now says beside its identity reconciliation introduction what the identity pairing source reaches (staged new nodes of the same kind across branches) and that it is not a consolidate-existing-entities operation; a future direct consolidation API builds on the reviewed merge machinery. - `IdentityReplayError` no longer raises `IDENTITY_REPLAY_LIMIT_EXCEEDED`; `IdentityReplay` and the `transitionsOf` result gain `nextFrom`. Callers that caught the code to page must read the cursor instead. - `IdentityTransition` gains the optional `restored` field. The identity reconciliation changeset carries the updated text. --- .changeset/identity-reconciliation.md | 68 +++- apps/docs/src/content/docs/errors.md | 23 +- apps/docs/src/content/docs/graph-merge.md | 24 ++ apps/docs/src/content/docs/identity.md | 73 +++- .../etc/typegraph-graph-merge.api.md | 14 +- .../etc/typegraph-interchange.api.md | 14 +- .../etc/typegraph-postgres-pglite.api.md | 14 +- .../typegraph/etc/typegraph-profiler.api.md | 14 +- .../typegraph/etc/typegraph-provenance.api.md | 14 +- .../etc/typegraph-sqlite-local.api.md | 14 +- packages/typegraph/etc/typegraph.api.md | 18 +- packages/typegraph/scripts/api-report.ts | 11 + packages/typegraph/src/errors/index.ts | 11 +- packages/typegraph/src/identity/index.ts | 1 + packages/typegraph/src/identity/replay.ts | 370 +++++++++++++----- .../typegraph/src/identity/transition-log.ts | 118 ++++-- packages/typegraph/src/identity/types.ts | 17 +- packages/typegraph/src/index.ts | 1 + .../backends/integration/identity-replay.ts | 63 +++ .../tests/backends/integration/identity.ts | 5 +- .../pglite-identity-transition-log.test.ts | 2 +- .../identity-reconciliation.test.ts | 6 +- .../tests/identity-import-hardening.test.ts | 44 ++- .../typegraph/tests/identity-replay.test.ts | 174 +++++++- .../tests/identity-transition-log.test.ts | 72 ++++ .../identity-replay-exhaustive.test.ts | 2 +- 26 files changed, 971 insertions(+), 216 deletions(-) diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 399dac054..5a1958bcb 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -9,19 +9,39 @@ retractions, same-id folds, deletes and restores, validity-window ends, kind drops, schema transitions and reconciliation decisions — each carrying the assertion ids involved, both temporal coordinates, and, for a decision made by a merge, the policy arm, branch, branch ancestry and plan and review digests -that produced it. `store.identity.replay(ref)` pairs each transition with the -class membership before and after it, reconstructed through the same -historical reader `asOf` and `asOfRecorded` reads already use, so replay can -never disagree with a live read. `pruneIdentityTransitions(store, { beforeRecorded })` -trims retained explanations and records a watermark that replay reports rather -than hiding, and archival interchange carries a `transitions` section plus the -retention watermark, bumping the interchange format to `3.0` (older documents -still import and validate unchanged).

The IRI overload of `equivalentTo` returned a bare `OntologyRelation`, so `equivalentTo(Company, iri)` plus `equivalentTo(Corporation, iri)` folded both kinds into one class at runtime while the type concluded `Company` was exact-kind: a default query could return a `Corporation` row branded as `Company` and dispatch it to the wrong collection. Every factory now returns a relation typed with its meta-edge name literal and endpoint kinds, the IRI overload included (`from: Kind, to: string`), so the type sees an IRI-routed equivalence on `Kind`. A relation that is only a bare `OntologyRelation` (reachable now only through a user annotation) widens every alias in that graph conservatively rather than silently under-widening. Type tests cover the IRI-routed case, a fully typed tuple staying exact where it should, and an annotated element widening; a runtime test pins the premise that IRI-routed kinds fold. **One `expansion` option.** `includeSubClasses` and `includeNarrower` were two mutually exclusive booleans that spelled a three-way choice through overloads. `from()`, `to()`, `fromDynamic()` and `toDynamic()` take `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`, the polymorphic default), `createStore`'s `queryDefaults.expansion` names the store-wide default (which excludes `"narrower"`, since an alias with no options is typed as its declared kind), and `search()` accepts the same option minus `"narrower"` and refuses an axis it cannot honor. Ordinary option forwarding works again: `{}` and an explicit `undefined` take the store default. `QueryAst`'s `start.expansion` replaces `start.includeSubClasses`. The two axis types are exported as `AliasExpansionAxis` and `DefaultAliasExpansionAxis`, and the search facade uses the latter rather than a third spelling. **Composition subgraphs type the edges they return.** `subgraph({ composition: true })` added realizing edge kinds to the adjacency at runtime while the result stayed keyed by the explicit `edges` list, leaving `never`-typed edge keys over populated adjacency with `edges: []`. The result is keyed by `SubgraphResultEdgeKinds`: the graph's full edge-kind union when composition is enabled, the `edges` list otherwise; the name is exported so a caller can store the result. - `includeSubClasses` / `includeNarrower` are replaced by `expansion` on the four alias entry points and by `queryDefaults.expansion` on `createStore`; `QueryAst.start.includeSubClasses` becomes `start.expansion`. - Annotating a relation as `OntologyRelation` now widens every alias in that graph; let the factory return type be inferred. - A `subgraph({ composition: true })` result's edge keys are the graph's edge-kind union rather than the `edges` list. The typed-subsumption and composition-navigation changesets carry the updated text, including the migration recipe for keeping the previous exact-kind behavior store-wide. --- .changeset/composition-navigation.md | 2 +- .changeset/typed-subsumption.md | 16 +- apps/docs/src/content/docs/architecture.md | 6 +- apps/docs/src/content/docs/core-concepts.md | 2 +- apps/docs/src/content/docs/ejecting.md | 2 +- .../docs/examples/document-management.md | 4 +- apps/docs/src/content/docs/fulltext-search.md | 10 +- .../docs/src/content/docs/graph-extensions.md | 2 +- apps/docs/src/content/docs/ontology.md | 80 +- .../src/content/docs/performance/overview.md | 6 +- .../src/content/docs/performance/profiler.md | 4 +- .../docs/src/content/docs/queries/overview.md | 2 +- apps/docs/src/content/docs/queries/source.md | 48 +- .../docs/src/content/docs/queries/traverse.md | 3 +- apps/docs/src/content/docs/schemas-stores.md | 19 +- apps/docs/src/content/docs/semantic-search.md | 12 +- apps/docs/src/content/docs/troubleshooting.md | 8 +- packages/benchmarks/README.md | 2 +- .../benchmarks/src/real/engines/ladybug.ts | 4 +- .../src/real/engines/typegraph-queries.ts | 4 +- .../benchmarks/src/real/schema/snb-graph.ts | 4 +- .../typegraph/etc/api-surface-exceptions.json | 1370 ++++++++++++++++- packages/typegraph/etc/typegraph.api.md | 162 +- .../examples/03-subclass-hierarchy.ts | 14 +- .../typegraph/examples/08-custom-ontology.ts | 18 +- packages/typegraph/examples/README.md | 2 +- packages/typegraph/src/index.ts | 5 + .../typegraph/src/ontology/core-meta-edges.ts | 87 +- packages/typegraph/src/ontology/types.ts | 29 +- .../typegraph/src/profiler/query-profiler.ts | 5 +- packages/typegraph/src/query/ast.ts | 2 +- packages/typegraph/src/query/builder.ts | 3 +- .../src/query/builder/alias-expansion.ts | 127 +- .../src/query/builder/query-builder.ts | 60 +- .../src/query/builder/traversal-builder.ts | 51 +- packages/typegraph/src/query/builder/types.ts | 140 +- .../compiler/emitter/standard-builders.ts | 4 +- .../typegraph/src/query/compiler/schema.ts | 2 +- packages/typegraph/src/query/index.ts | 4 + .../validate-structural-subsumption.ts | 2 +- .../src/store/collections/node-collection.ts | 10 +- packages/typegraph/src/store/index.ts | 1 + packages/typegraph/src/store/runtime-port.ts | 10 +- packages/typegraph/src/store/search.ts | 71 +- packages/typegraph/src/store/store-view.ts | 17 +- packages/typegraph/src/store/store.ts | 35 +- packages/typegraph/src/store/subgraph.ts | 66 +- packages/typegraph/src/store/types.ts | 16 +- packages/typegraph/test-d/ontology.test-d.ts | 160 +- .../integration/ontology-typed-subsumption.ts | 40 +- .../postgres/fulltext-gin-language.test.ts | 4 +- .../typegraph/tests/matches-predicate.test.ts | 10 +- .../tests/polymorphic-default.test.ts | 74 +- packages/typegraph/tests/profiler.test.ts | 8 +- .../typegraph/tests/query-builder.test.ts | 12 +- .../typegraph/tests/query-execution.test.ts | 6 +- .../tests/search-filter-pushdown.test.ts | 12 +- packages/typegraph/tests/subgraph.test.ts | 172 +++ .../tests/typed-subsumption-types.test.ts | 460 +++++- .../typegraph/tests/vector-compiler.test.ts | 8 +- 60 files changed, 3003 insertions(+), 516 deletions(-) diff --git a/.changeset/composition-navigation.md b/.changeset/composition-navigation.md index b4417721f..f607613ad 100644 --- a/.changeset/composition-navigation.md +++ b/.changeset/composition-navigation.md @@ -4,7 +4,7 @@ `QueryBuilder` gains `parts()` and `wholes()`, declared-structure builder sugar over the existing recursive `Traversal` AST for a declared [composition](https://typegraph.dev/ontology#composition) relation (`partOf` / `hasPart`).

charset=UTF-8 Content-Transfer-Encoding: 8bit Composition lifecycle revisions from the first whole-branch review of the integration branch: the attachment input, an atomic ownership transfer, get-or-create idempotence, cascade visibility, complete owned-unit exports, and a documentation pass that states what ships instead of what was once planned. The composition part lifecycle is complete: a part names the edge that realizes its attachment, moves between wholes as one atomic operation, and reports what a whole's deletion took with it. **The attachment names its realizing edge.** `partOf` — on `create`, `bulkCreate`'s per-item options, and both get-or-create entries — becomes `{ kind, id, via?, props? }`. `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `ConfigurationError` (`COMPOSITION_VIA_AMBIGUOUS`) instead of resolving the ambiguity by sort order, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would — so a realizing edge with required schema fields is now attachable from a node create at all. That validation runs on every call that states `props`, including a `getOrCreateByConstraint`/`reparent` call that resolves to an attachment already holding: those write no edge, but still refuse a schema-invalid value, and still refuse (`CompositionExistenceError`, `situation: "props"`) a valid value that differs from the edge's live stored props rather than silently keeping the old one. `resolveCompositionAttachment` is the one owner of both refusals; `KindRegistry.getCompositionEdge`'s silent first-match resolution is gone. **`nodes..reparent(id, attachment)` moves a part to a new whole.** Neither half of a move is legal on its own — the new attachment refuses while the old edge holds the part's one-whole claim, and `existence: "required"` refuses the detach while the part is live — so a caller had no legal order to write. `reparent` performs both under one per-graph fence, in one transaction, and validates the FINAL state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties, and every descendant beneath it. How the old attachment retires follows its declared population: a `population: "one"` edge is deleted, removing the attachment from every `store.asOf(t)` read at every coordinate before the move (a `one` binding persists for the row's whole life, so an ended row would still read as an attachment); a `population: "oneActive"` edge instead has its window ended at the move instant, leaving the previous membership readable as valid-time history. The population comes from the INCUMBENT row's own pair, resolved through the realizing edge that holds the attachment. The move instant is read ONCE and is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none shows it with two. Reparenting to the whole the part already holds is accepted as a no-op — no write, no history — though a stated `props` is still checked: valid and value-identical to the edge's live stored props, the no-op stands, and a valid but different value refuses (`situation: "props"`) rather than being silently dropped. **`partOf` on `getOrCreateByConstraint` is now a POSTCONDITION, not a create-only option.** When the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies it — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`situation: "props"`) rather than silently kept, since a satisfied match writes no edge. A node with no live whole has the attachment written now, whatever its pair's declared `existence`; a node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused with `CompositionExistenceError` (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. This reverses the previous unconditional refusal, which made a re-run of the same get-or-create fail purely because it was a re-run. **A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts` — leaf-first `{ kind, id }` refs, taken from the plan the cascade executed, so they never name a part the cascade did not delete. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order; the batch path still emits no per-item operation hooks. `onOperationStart` never carries them (the cascade has not been planned yet), and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. **`subgraph({ composition: true })` returns the COMPLETE owned unit.** The composition closure is bounded by its visited set, never by `maxDepth`: a part tree deeper than the default depth now comes back whole, because a whole plus a truncated prefix of its parts is not an export unit. `maxDepth` and `cyclePolicy` continue to bound the explicit `edges` traversal alone. The engine's own runaway ceiling on any recursive traversal (1000 hops) still applies to the composition closure, and truncates rather than refusing past it. The ontology, errors, and limitations pages are rewritten to state what composition enforces today — one whole per part across every relation and both orientations, leaf-first cascade, acyclicity over the oriented composition union at write time, and `existence: "required"` — replacing the "planned for tier 1" and "forthcoming claim provisioning" language those pages still carried. - `KindRegistry.getCompositionEdge(partKind, wholeKind)` is removed. Use `compositionPairsBetween(partKind, wholeKind)` (every declared pair, code-point ordered by realizing edge kind) or `compositionPairVia(partKind, wholeKind, viaEdgeKind)` (the pair a known realizing edge holds). The removed reader answered with the code-point-first pair alone, which silently chose a realizing edge for its caller. - `partOf` on `create` / `bulkCreate` / `getOrCreateByConstraint` / `bulkGetOrCreateByConstraint` is typed `CompositionAttachment` (`{ kind, id, via?, props? }`) rather than `CompositionWholeRef`. Existing `{ kind, id }` call sites are unchanged, but a part kind with more than one declared pair toward the named whole kind now refuses until the call states `via`. - `getOrCreateByConstraint` / `bulkGetOrCreateByConstraint` no longer refuse every `partOf` stated against a `"found"` / `"updated"` result. Code that relied on the refusal as a "this node already existed" signal must check the returned `action` instead. - `TransactionReceipt` gains a required `cascadedParts` field (always present, empty when the transaction deleted no composition whole); anything constructing a receipt literal must add it. - `OperationHookContext` gains an optional `cascadedParts`, and `StoreHooks`' runner signature gains a fourth, optional operation-facts argument; a hand-written hook runner implementing that internal shape needs the extra parameter. - `CompositionExistenceErrorDetails` gains `currentVia`, `requestedWhole`, and `requestedVia` (all optional, `situation: "existing"` only), and the `"existing"` message now names both the held and the requested attachment. `requestedVia` carries the RESOLVED realizing edge rather than an echo of a stated `via`, so it is present even when the call omitted one. `situation` also gains `"props"`, with `currentProps`/`requestedProps` (optional, `situation: "props"` only) — a `getOrCreateByConstraint`/`reparent` call resolving to an attachment that already holds is now refused, rather than silently ignored, when its stated `props` are schema-valid but differ from the edge's live stored props. - `NodeCollection` gains `reparent`; a hand-written implementation of that interface (rather than one built by `createStore`) must add it. `resolveCompositionAttachment` is the one owner of "what edge does this part owe" for every attachment surface (create, bulk create, both get-or-create entries, reparent): it resolves `via` when the part kind has more than one declared pair toward the whole kind and refuses ambiguity or an undeclared edge before any row is written, and the props flow through the same edge-create validation an explicit `edges..create` would run, so there is no second schema parse. `reparent` retires the current composition edge by its pair's population (`one` deletes, `oneActive` ends the window) and attaches the new one inside one transaction under the per-graph fence, validating the final state so a required-existence part is never observably without a whole; moving to the same whole is a no-op. The get-or-create postcondition makes a repeated identical call idempotent and lets concurrent callers converge through the existing uniqueness retry, which reverses the earlier create-only ruling. The cascade's affected parts reach hooks and receipts through a new operation-facts seam fed by the plan the cascade executed, so the count and the reported refs cannot disagree. The composition closure in `subgraph` is bounded by its visited set rather than `maxDepth`; the engine's recursive-traversal ceiling still applies and is documented as truncation rather than refusal. The rewritten ontology page states tier 1's guarantees as enforced today (one whole per part across every relation and both orientations, acyclicity over the oriented composition union at write time, leaf-first cascade, `existence: "required"`, complete owned-unit export) and the `CompositionCycleError` docblock now says a ring can only reach the cascade through rows that bypassed the write fence. --- .changeset/composition-attachment.md | 27 + apps/docs/src/content/docs/core-concepts.md | 7 +- apps/docs/src/content/docs/errors.md | 83 +- apps/docs/src/content/docs/limitations.md | 29 +- apps/docs/src/content/docs/ontology.md | 197 +++- .../typegraph/etc/api-surface-exceptions.json | 992 +++++++++++++++++- .../etc/typegraph-graph-merge.api.md | 34 +- .../etc/typegraph-interchange.api.md | 34 +- .../etc/typegraph-postgres-pglite.api.md | 34 +- .../typegraph/etc/typegraph-profiler.api.md | 34 +- .../typegraph/etc/typegraph-provenance.api.md | 34 +- .../typegraph/etc/typegraph-schema.api.md | 3 +- .../etc/typegraph-sqlite-local.api.md | 34 +- packages/typegraph/etc/typegraph.api.md | 47 +- packages/typegraph/src/errors/index.ts | 96 +- packages/typegraph/src/graph-merge/merge.ts | 5 +- packages/typegraph/src/index.ts | 2 + .../typegraph/src/registry/kind-registry.ts | 43 +- .../typegraph/src/store/collection-factory.ts | 7 + .../typegraph/src/store/collection-surface.ts | 1 + .../src/store/collections/node-collection.ts | 15 + .../store/operations/composition-cascade.ts | 56 +- .../store/operations/composition-create.ts | 251 ++++- .../src/store/operations/edge-operations.ts | 43 + .../typegraph/src/store/operations/index.ts | 1 + .../src/store/operations/node-operations.ts | 483 ++++++++- .../src/store/operations/write-executor.ts | 23 +- .../src/store/operations/write-transaction.ts | 8 +- packages/typegraph/src/store/store.ts | 59 +- packages/typegraph/src/store/subgraph.ts | 16 +- .../src/store/transaction-receipt.ts | 19 + packages/typegraph/src/store/types.ts | 174 ++- .../tests/backends/integration-test-suite.ts | 2 + .../integration/composition-attachment.ts | 990 +++++++++++++++++ .../integration/composition-existence.ts | 30 +- .../integration/composition-navigation.ts | 36 + .../tests/backends/integration/index.ts | 1 + .../tests/composition-cascade.test.ts | 144 +++ .../composition-reparent-instant.test.ts | 152 +++ .../graph-merge/composition-orphan.test.ts | 9 +- .../ontology-composition-declaration.test.ts | 20 +- 41 files changed, 3896 insertions(+), 379 deletions(-) create mode 100644 .changeset/composition-attachment.md create mode 100644 packages/typegraph/tests/backends/integration/composition-attachment.ts create mode 100644 packages/typegraph/tests/composition-reparent-instant.test.ts diff --git a/.changeset/composition-attachment.md b/.changeset/composition-attachment.md new file mode 100644 index 000000000..6ad88aff7 --- /dev/null +++ b/.changeset/composition-attachment.md @@ -0,0 +1,27 @@ +--- +"@nicia-ai/typegraph": minor +--- + +The composition part lifecycle is complete: a part names the edge that realizes its attachment, moves between wholes as one atomic operation, and reports what a whole's deletion took with it. + +**The attachment names its realizing edge.** `partOf` — on `create`, `bulkCreate`'s per-item options, and both get-or-create entries — becomes `{ kind, id, via?, props? }`. `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `ConfigurationError` (`COMPOSITION_VIA_AMBIGUOUS`) instead of resolving the ambiguity by sort order, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would — so a realizing edge with required schema fields is now attachable from a node create at all. That validation runs on every call that states `props`, including a `getOrCreateByConstraint`/`reparent` call that resolves to an attachment already holding: those write no edge, but still refuse a schema-invalid value, and still refuse (`CompositionExistenceError`, `situation: "props"`) a valid value that differs from the edge's live stored props rather than silently keeping the old one. `resolveCompositionAttachment` is the one owner of both refusals; `KindRegistry.getCompositionEdge`'s silent first-match resolution is gone. + +**`nodes..reparent(id, attachment)` moves a part to a new whole.** Neither half of a move is legal on its own — the new attachment refuses while the old edge holds the part's one-whole claim, and `existence: "required"` refuses the detach while the part is live — so a caller had no legal order to write. `reparent` performs both under one per-graph fence, in one transaction, and validates the FINAL state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties, and every descendant beneath it. How the old attachment retires follows its declared population: a `population: "one"` edge is deleted, removing the attachment from every `store.asOf(t)` read at every coordinate before the move (a `one` binding persists for the row's whole life, so an ended row would still read as an attachment); a `population: "oneActive"` edge instead has its window ended at the move instant, leaving the previous membership readable as valid-time history. The population comes from the INCUMBENT row's own pair, resolved through the realizing edge that holds the attachment. The move instant is read ONCE and is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none shows it with two. Reparenting to the whole the part already holds is accepted as a no-op — no write, no history — though a stated `props` is still checked: valid and value-identical to the edge's live stored props, the no-op stands, and a valid but different value refuses (`situation: "props"`) rather than being silently dropped. + +**`partOf` on `getOrCreateByConstraint` is now a POSTCONDITION, not a create-only option.** When the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies it — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`situation: "props"`) rather than silently kept, since a satisfied match writes no edge. A node with no live whole has the attachment written now, whatever its pair's declared `existence`; a node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused with `CompositionExistenceError` (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. This reverses the previous unconditional refusal, which made a re-run of the same get-or-create fail purely because it was a re-run. + +**A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts` — leaf-first `{ kind, id }` refs, taken from the plan the cascade executed, so they never name a part the cascade did not delete. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order; the batch path still emits no per-item operation hooks. `onOperationStart` never carries them (the cascade has not been planned yet), and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. + +**`subgraph({ composition: true })` returns the COMPLETE owned unit.** The composition closure is bounded by its visited set, never by `maxDepth`: a part tree deeper than the default depth now comes back whole, because a whole plus a truncated prefix of its parts is not an export unit. `maxDepth` and `cyclePolicy` continue to bound the explicit `edges` traversal alone. The engine's own runaway ceiling on any recursive traversal (1000 hops) still applies to the composition closure, and truncates rather than refusing past it. + +The ontology, errors, and limitations pages are rewritten to state what composition enforces today — one whole per part across every relation and both orientations, leaf-first cascade, acyclicity over the oriented composition union at write time, and `existence: "required"` — replacing the "planned for tier 1" and "forthcoming claim provisioning" language those pages still carried. + +### Breaking + +- `KindRegistry.getCompositionEdge(partKind, wholeKind)` is removed.

A union endpoint matches no such shape, so the decision answered `false` for every kind the endpoint can hold — an unsound under-widening, the opposite of the conservative over-widening the erased arms take on purpose. The decision now reduces each relation's `MatchedEndpoints` to the kind literals its endpoints can hold and asks whether `K` is among them. That covers both spellings of a union endpoint: a union of endpoint types (from a helper that declares a subclass of either of two roots) and a union inside one endpoint's `kind` (`NodeType<"Audio" | "Video">`). `MatchedEndpoints` is the sole owner of the name-to-endpoint-position mapping; the decided arm no longer re-spells it as `Extract` arms beside the erased arm's use of it, and both erased arms are unchanged. A union endpoint therefore widens exactly the kinds it can hold and nothing else, which the typed-subsumption changeset and the queries guide now state.

The only dimension callers differ on is the explicit disposition the write plan carries: `nodes..reparent(...)` states `onIncumbent: "replace"`, every get-or-create path states `"refuse"`. Before this, the get-or-create `partOf` postcondition decided from a lock-free read and then called the reparent machinery, whose fenced re-read always replaced, so two callers that each asked for a different whole could both observe "no whole yet" and the second one silently moved the part instead of refusing. The lock-free read survives only as a pre-check that lets an already-satisfied call stay read-only, stated `props` included (`incumbentSatisfiesRequestedAttachment`, built on the same props verdict the refusal reads); every verdict and every write comes from the fenced read. `resolveCompositionAttachmentRequest` is the one resolver every attachment surface reaches. A new two-connection test in the concurrency suite proves the race outcome (one attachment, one refusal) on real overlapping writers rather than an in-process interleaving. writes The existing-row `ifExists: "update"` and resurrection legs run the attachment inside the same transaction as the property update (`executeNodeUpsertUpdate`'s `compositionAttachment`). Because that leg runs on a caller's enclosing `store.transaction(...)` when there is one, with no nested frame to roll back, the frame is ordered so every read the attachment owes precedes the update's first statement: the fenced incumbent decision and the whole's liveness (`decideCompositionAttachmentUnderFence`, which now carries `lock: GraphWriteLock` as compile-time evidence like `assertCompositionExistencePreserved`), then the realizing edge's own preparation (`prepareCompositionAttachmentDecision`: the part's liveness on the update leg, cardinality, acyclicity, the required-existence rule). `attachCompositionCreateEdge` is split into that read half and `insertPreparedCompositionEdge`, and the leg issues only the insert after the update. A refusal from any read leaves nothing written, and a refused property update (a unique conflict, a validation error) never reaches the insert, so ownership and history stay untouched in every case. The resurrection leg skips only the part endpoint read, since its row is a tombstone until the update restores it; the whole is still refused at decide time. `assertEndpointRowLive` is the one row-liveness predicate both `assertLiveEdgeEndpoints` and the decide half call. Load-bearing tests cover a conflicting incumbent, a dead whole, and a whole-side cardinality refusal, each caught inside an enclosing transaction with the property left unapplied; each fails with the corresponding read moved back below the update. A whole deleted through a `tx.measure(...)` scope counted as one write in that scope's sub-receipt but contributed nothing to its `cascadedParts`: cascade refs travel through the node operation context, and a scope was built by wrapping the outer context's collections a second time. A transaction's write surface (collections, identity facade, and the node operation context they bind to) is now built by one parameterized builder, and a measure scope rebuilds it against the whole recorder chain; `recordCascadedParts` fans out along that chain, so a measured delete populates the scope's receipt and every receipt enclosing it. The scope also overlays the runtime's internal delete port with one built from its own surface, so a delete issued through that port inside a scope is attributed to the scope. Attribution stays structural, by the context the write ran through, never by timing. `subgraph({ composition: true })` walked its part closure with a hop-bounded recursive CTE capped at 1,000 levels, so a deeper part chain came back truncated, which is not an export unit. The closure is now `buildExhaustiveDirectedReachableCte`: `UNION` over a frontier of exactly `(id, kind)`, the same device that makes the composition-union acyclicity probe exhaustive, so it reaches a fixpoint on any finite graph with no depth ceiling, no path column, and no cycle policy. `maxDepth` and `cyclePolicy` continue to bound the `edges` traversal a caller lists alongside the closure. An engine that cuts the closure statement short (a `statement_timeout`, a cancelled query) is refused with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) through the same `isStatementCutShortError` predicate the probe uses, instead of surfacing an opaque driver error. The hop-bounded directed builder had no other caller and is removed. The ontology and limitations pages state completeness as delivered. Both surfaces are new in this release, so the incumbent disposition and the exhaustive closure are stated in their changesets as delivered behavior rather than as breaking changes. --- .changeset/composition-attachment.md | 6 +- .changeset/composition-navigation.md | 2 +- apps/docs/src/content/docs/limitations.md | 8 +- apps/docs/src/content/docs/ontology.md | 12 +- .../store/operations/composition-create.ts | 483 +++++++++- .../src/store/operations/edge-operations.ts | 33 +- .../src/store/operations/node-operations.ts | 836 ++++++++++++------ packages/typegraph/src/store/recursive-cte.ts | 161 +++- packages/typegraph/src/store/store.ts | 277 ++++-- packages/typegraph/src/store/subgraph.ts | 55 +- .../integration/composition-attachment.ts | 54 +- .../integration/composition-existence.ts | 14 +- .../concurrent-constraint-fence.test.ts | 104 ++- .../composition-attachment-fence.test.ts | 552 ++++++++++++ .../tests/composition-cascade.test.ts | 111 +++ .../composition-reparent-instant.test.ts | 7 +- .../tests/composition-subgraph-depth.test.ts | 175 ++++ .../recursive-traversal-inventory.test.ts | 13 +- 18 files changed, 2408 insertions(+), 495 deletions(-) create mode 100644 packages/typegraph/tests/composition-attachment-fence.test.ts create mode 100644 packages/typegraph/tests/composition-subgraph-depth.test.ts diff --git a/.changeset/composition-attachment.md b/.changeset/composition-attachment.md index 6ad88aff7..338ce808c 100644 --- a/.changeset/composition-attachment.md +++ b/.changeset/composition-attachment.md @@ -10,9 +10,11 @@ The composition part lifecycle is complete: a part names the edge that realizes **`partOf` on `getOrCreateByConstraint` is now a POSTCONDITION, not a create-only option.** When the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies it — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`situation: "props"`) rather than silently kept, since a satisfied match writes no edge. A node with no live whole has the attachment written now, whatever its pair's declared `existence`; a node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused with `CompositionExistenceError` (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. This reverses the previous unconditional refusal, which made a re-run of the same get-or-create fail purely because it was a re-run. -**A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts` — leaf-first `{ kind, id }` refs, taken from the plan the cascade executed, so they never name a part the cascade did not delete. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order; the batch path still emits no per-item operation hooks. `onOperationStart` never carries them (the cascade has not been planned yet), and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. +Which of those three dispositions applies is decided under the per-graph write fence, from the incumbent re-read there — never from a lock-free read. `reparent` and the get-or-create postcondition are one write plan that takes an explicit incumbent disposition: `reparent` states "replace" (moving a part is what it is for), every get-or-create path states "refuse". So two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError` — never a silent move, whatever order their lookups observed. A get-or-create whose `ifExists: "update"` also runs ONE write plan: the attachment and the property update commit together in the ordinary case, so an update the row refuses (a unique conflict, a validation error) leaves ownership and history untouched instead of committing a move whose reason never applied. Every read the attachment owes — the fenced incumbent decision (a different held whole, the same whole through a different realizing edge, a stated `props` value the live edge disagrees with), the whole's liveness, and the realizing edge's own preparation (the part's liveness, cardinality, acyclicity, the required-existence rule) — runs before the update's first statement, so a refusal from any of them leaves the properties untouched too, including when the caller catches the refusal inside an enclosing `store.transaction(...)`, where there is no nested frame to roll back. The only attachment statement after the update is the edge insert itself, whose claim rows are the database backstop for verdicts the fenced reads already reached. An already-satisfied call with no update to make stays read-only, restating the realizing edge's `props` included: agreeing props are part of what "already satisfied" means, so an idempotent ingest does not take the per-graph write fence to be told it has nothing to write. -**`subgraph({ composition: true })` returns the COMPLETE owned unit.** The composition closure is bounded by its visited set, never by `maxDepth`: a part tree deeper than the default depth now comes back whole, because a whole plus a truncated prefix of its parts is not an export unit. `maxDepth` and `cyclePolicy` continue to bound the explicit `edges` traversal alone.

The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order; the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, alongside the transaction's own receipt, attributed the same way its write counters are — by the context the write ran through, not by timing, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them (the cascade has not been planned yet), and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. + +**`subgraph({ composition: true })` returns the COMPLETE owned unit.** The composition closure is bounded by its visited set, never by `maxDepth`: a part tree deeper than the default depth comes back whole, because a whole plus a truncated prefix of its parts is not an export unit.

Delivered or refused, never partial, against the engine as well: a closure statement the database cut short (a `statement_timeout`, a cancelled query) refuses with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) naming the root, through the same cut-short classification the acyclicity probe uses, rather than returning the rows it reached. `maxDepth` and `cyclePolicy` continue to bound the explicit `edges` traversal alone. The ontology, errors, and limitations pages are rewritten to state what composition enforces today — one whole per part across every relation and both orientations, leaf-first cascade, acyclicity over the oriented composition union at write time, and `existence: "required"` — replacing the "planned for tier 1" and "forthcoming claim provisioning" language those pages still carried. diff --git a/.changeset/composition-navigation.md b/.changeset/composition-navigation.md index f607613ad..96a8dfb65 100644 --- a/.changeset/composition-navigation.md +++ b/.changeset/composition-navigation.md @@ -4,7 +4,7 @@ `QueryBuilder` gains `parts()` and `wholes()`, declared-structure builder sugar over the existing recursive `Traversal` AST for a declared [composition](https://typegraph.dev/ontology#composition) relation (`partOf` / `hasPart`).

Preparation can still refuse (cardinality at the new whole, acyclicity over the composition union, the realizing edge's props), and because the write path has no savepoint, a caller that catches that refusal inside an enclosing `store.transaction(...)` let the retirement commit without the replacement, leaving the part detached, a required-existence part included. The replacement is now prepared before the incumbent is retired, and the frame issues only the retire and the insert after every read has passed, the same reads-then-writes order the get-or-create update leg already follows. Simply moving the preparation earlier would have refused every move whose incumbent realizes the same edge kind, because the incumbent still counts against the part's own cardinality until it is retired. So the preparation reads through `createRetiringEdgeValidationBackend`, a read overlay beside the existing in-batch cardinality overlay in `edge-batch-validation.ts`, which subtracts the retiring row from any endpoint count that includes it. That yields exactly the count the insert will see: a `population: "one"` incumbent is soft-deleted and leaves a `live` count, a `population: "oneActive"` incumbent has its window ended and leaves a `liveAndActive` count, and a pair's population is the very axis whose count it leaves. `edgeExistsBetween` is not overlaid because an incumbent sharing the replacement's `(kind, from, to)` is the same attachment, which the fenced decision reports as satisfied and never replaces. The row-level rendering of the count predicate sits beside the cache key that already mirrors the same tuple, so the two renderings of one read live in one place. The load-bearing test moves a part to a whole that already holds its one part, catches the `CardinalityError` inside a transaction, and asserts the incumbent attachment is still open. With the preparation moved back below the retirement it fails with the part holding no attachment at all, which is the reviewed scenario. Also from that review: the composition-attachment changeset states the reparent order, and the internal comments around the get-or-create leg are shortened to each caller's obligation, with the sequencing invariant kept beside `prepareCompositionAttachmentDecision` and the reason the replacement needs its own count beside the overlay. --- .changeset/composition-attachment.md | 2 +- .../store/operations/edge-batch-validation.ts | 67 ++++++++++++++++++ .../src/store/operations/node-operations.ts | 68 +++++++++---------- .../backend-derivation-inventory.test.ts | 6 ++ .../composition-attachment-fence.test.ts | 46 +++++++++++++ 5 files changed, 154 insertions(+), 35 deletions(-) diff --git a/.changeset/composition-attachment.md b/.changeset/composition-attachment.md index 338ce808c..d9183c9f2 100644 --- a/.changeset/composition-attachment.md +++ b/.changeset/composition-attachment.md @@ -6,7 +6,7 @@ The composition part lifecycle is complete: a part names the edge that realizes **The attachment names its realizing edge.** `partOf` — on `create`, `bulkCreate`'s per-item options, and both get-or-create entries — becomes `{ kind, id, via?, props? }`. `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `ConfigurationError` (`COMPOSITION_VIA_AMBIGUOUS`) instead of resolving the ambiguity by sort order, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would — so a realizing edge with required schema fields is now attachable from a node create at all. That validation runs on every call that states `props`, including a `getOrCreateByConstraint`/`reparent` call that resolves to an attachment already holding: those write no edge, but still refuse a schema-invalid value, and still refuse (`CompositionExistenceError`, `situation: "props"`) a valid value that differs from the edge's live stored props rather than silently keeping the old one. `resolveCompositionAttachment` is the one owner of both refusals; `KindRegistry.getCompositionEdge`'s silent first-match resolution is gone. -**`nodes..reparent(id, attachment)` moves a part to a new whole.** Neither half of a move is legal on its own — the new attachment refuses while the old edge holds the part's one-whole claim, and `existence: "required"` refuses the detach while the part is live — so a caller had no legal order to write. `reparent` performs both under one per-graph fence, in one transaction, and validates the FINAL state: one whole, acyclicity over the oriented composition union, and a required part never left detached.

The population comes from the INCUMBENT row's own pair, resolved through the realizing edge that holds the attachment. The move instant is read ONCE and is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none shows it with two. Reparenting to the whole the part already holds is accepted as a no-op — no write, no history — though a stated `props` is still checked: valid and value-identical to the edge's live stored props, the no-op stands, and a valid but different value refuses (`situation: "props"`) rather than being silently dropped. +**`nodes..reparent(id, attachment)` moves a part to a new whole.** Neither half of a move is legal on its own — the new attachment refuses while the old edge holds the part's one-whole claim, and `existence: "required"` refuses the detach while the part is live — so a caller had no legal order to write. `reparent` performs both under one per-graph fence, in one transaction, and validates the FINAL state: one whole, acyclicity over the oriented composition union, and a required part never left detached.

A node that already holds this whole through the resolved pair's realizing edge satisfies it — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`situation: "props"`) rather than silently kept, since a satisfied match writes no edge. A node with no live whole has the attachment written now, whatever its pair's declared `existence`; a node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused with `CompositionExistenceError` (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item.

That was the only CI failure; the Build job was the aggregate gate reporting it. ## Documentation The equivalence-is-subsumption changeset told readers to drop `includeSubClasses` to stop expansion. Omission now defaults to subclass expansion, so it names `expansion: "exact"` and points at the typed-subsumption changeset for the migration. `cascadedParts` is documented where receipts and hooks are introduced, not only on the limitations page: the receipt guide gains a worked example of a whole's delete reporting its parts on the `onOperationEnd` context, on the `transactionWithReceipt` receipt, and on a `tx.measure` scope's receipt, and states that cascaded parts are refs beside the write-intent counters and never folded into them. The displayed `OperationHookContext` definition carries the field. The identity guide's first `transitionsOf` example read as complete while discarding `nextFrom`; it now says a page and shows the paging loop first, with a single call described as the first page. The source guide annotated the widened alias kind as a literal union; the comment separates the runtime values from the static type. The get-or-create `partOf` postcondition moves out of the required-existence refusals into its own subsection with an outcome table, since it applies to optional parts too and most of its outcomes are successes; the required-existence list is now two refusals with a pointer to it. Two runnable examples cover the workflows the review found untaught. `28-composition-lifecycle.ts` declares a required pair whose realizing edge carries a required property, refuses a bare create, attaches through `getOrCreateByConstraint`'s postcondition (created, found, refused for a different whole), reparents between wholes and to the current whole as a no-op, exports the complete owned unit with `subgraph({ composition: true })`, and reads the cascade from an `onOperationEnd` hook and a receipt. `29-identity-history.ts` pages `transitionsOf` and `replay` on `nextFrom` with a limit small enough to produce several pages, prunes with `pruneIdentityTransitions` and shows the no-op below the watermark, and labels restored transitions after a real archival export and import into a second history-enabled store. Both run under `pnpm test:examples`. Writing the examples surfaced five facts the guides did not state, now added: `CompositionExistenceError.code` is constant across situations so callers branch on `details.situation`; `reparent` writes a new realizing edge and so restates required edge props; one retraction on a class of three or more members can record more than one `retract` transition; an archival import that carries a live assertion records one native transition on the target beside the restored rows, on an empty target too; and restored rows keep the source graph's revision, so "oldest first" can list them before or after native rows regardless of when they happened. --- .changeset/equivalence-is-subsumption.md | 2 +- apps/docs/src/content/docs/errors.md | 4 +- apps/docs/src/content/docs/identity.md | 59 ++- apps/docs/src/content/docs/ontology.md | 62 ++- apps/docs/src/content/docs/queries/source.md | 5 +- apps/docs/src/content/docs/schemas-stores.md | 116 +++++ .../examples/28-composition-lifecycle.ts | 472 ++++++++++++++++++ .../typegraph/examples/29-identity-history.ts | 380 ++++++++++++++ packages/typegraph/examples/README.md | 2 + .../composition-attachment-fence.test.ts | 8 +- 10 files changed, 1062 insertions(+), 48 deletions(-) create mode 100644 packages/typegraph/examples/28-composition-lifecycle.ts create mode 100644 packages/typegraph/examples/29-identity-history.ts diff --git a/.changeset/equivalence-is-subsumption.md b/.changeset/equivalence-is-subsumption.md index 84846b2f7..a4d5559ba 100644 --- a/.changeset/equivalence-is-subsumption.md +++ b/.changeset/equivalence-is-subsumption.md @@ -6,7 +6,7 @@ ## Breaking changes -- `includeSubClasses: true` on `from()` / `to()` and on `search()` now returns rows of kinds declared `equivalentTo` the queried kind, not only its `subClassOf` descendants.

One owner replaces each repeated decision: claim ordering (sortedByClaimTarget), claim-target identity, the composition row's part and whole endpoints, the whole-side flip, the composition pair a live row realizes, the composition axis ref, the edge-write fence reason, the in-frame node delete every delete path and the cascade run, the recursive frontier branch's join shape, the opposing-relation detector, the post-retraction aftermath, the ordered class-pair key, the schema-commit capability error, the composition-only ontology fields, the per-part-kind uniformity check, and the kind registry's mirrored composition readers, which are now memoized. Tuple keys go through encodeTupleKey; probe ordering compares tuples rather than encoded keys. The mixed-orientation recursive CTE applies the edge temporal filter in its arms so only currently visible edge versions are normalized. Unattached required parts are read one batched statement per page, with every negative verdict still confirmed per row. A node validity-window end reads the closure only when the node has a materialized class. Sixteen positional merge-plan parameters become one options object. Internal planning codes and review history are removed from comments, keeping each invariant beside its owner. nodeDeleteNeedsConstraintFence now reports "edgeComposition" for a composition-whole delete instead of the earlier placeholder reason. --- packages/typegraph/src/backend/drizzle/ddl.ts | 21 + .../backend/drizzle/operation-backend-core.ts | 179 +++---- .../operations/constraint-fence-audit.ts | 131 +++-- .../backend/drizzle/operations/edge-claims.ts | 113 ++++- .../src/backend/drizzle/operations/shared.ts | 40 +- .../typegraph/src/backend/drizzle/sqlite.ts | 80 +-- .../typegraph/src/backend/sqlite/local.ts | 68 +-- packages/typegraph/src/constraints/index.ts | 10 - .../typegraph/src/graph-extension/remove.ts | 6 +- .../src/graph-merge/identity-pairing.ts | 49 +- .../src/graph-merge/identity-three-way.ts | 459 +++++++++--------- packages/typegraph/src/graph-merge/merge.ts | 340 +++++++++---- .../src/graph-merge/typegraph-internal.ts | 6 +- packages/typegraph/src/identity/replay.ts | 19 +- packages/typegraph/src/identity/separation.ts | 70 +-- .../src/identity/service-components.ts | 32 +- .../typegraph/src/identity/service-facade.ts | 178 ++++--- .../src/identity/service-maintenance.ts | 32 +- .../src/identity/service-mutation.ts | 85 ++-- .../typegraph/src/identity/transition-log.ts | 15 +- packages/typegraph/src/interchange/import.ts | 63 +-- packages/typegraph/src/ontology/validation.ts | 67 +-- packages/typegraph/src/provenance/index.ts | 13 +- .../src/query/builder/query-builder.ts | 51 +- .../typegraph/src/query/compiler/recursive.ts | 47 +- .../typegraph/src/registry/build-validated.ts | 59 ++- .../src/registry/composition-relation.ts | 258 +++++----- .../src/registry/edge-endpoint-allowance.ts | 22 +- .../typegraph/src/registry/edge-kind-facts.ts | 8 +- .../typegraph/src/registry/kind-registry.ts | 183 ++++--- .../src/registry/validate-implies.ts | 19 +- .../src/registry/validate-inverse.ts | 22 +- packages/typegraph/src/schema/manager.ts | 42 +- .../typegraph/src/schema/ontology-change.ts | 83 ++-- .../src/schema/structural-subtype.ts | 25 +- .../src/schema/tightening-preflight.ts | 89 +--- packages/typegraph/src/schema/types.ts | 5 +- packages/typegraph/src/store/acyclicity.ts | 240 +++++---- packages/typegraph/src/store/claims/axis.ts | 19 + .../src/store/claims/composition-claims.ts | 58 +-- .../typegraph/src/store/claims/edge-claims.ts | 74 +-- packages/typegraph/src/store/claims/verify.ts | 25 +- packages/typegraph/src/store/constraints.ts | 29 +- .../store/operations/composition-cascade.ts | 129 +++-- .../store/operations/composition-create.ts | 196 ++++++-- .../src/store/operations/edge-operations.ts | 131 ++--- .../src/store/operations/node-operations.ts | 245 +++++----- packages/typegraph/src/store/recursive-cte.ts | 92 ++-- packages/typegraph/src/store/store.ts | 11 +- packages/typegraph/src/store/subgraph.ts | 6 +- packages/typegraph/src/utils/compare.ts | 21 + packages/typegraph/src/utils/sql-errors.ts | 36 +- .../tests/composition-cascade.test.ts | 6 +- .../tests/recursive-compiler.test.ts | 42 +- packages/typegraph/tests/sql-errors.test.ts | 19 +- 55 files changed, 2454 insertions(+), 1914 deletions(-) diff --git a/packages/typegraph/src/backend/drizzle/ddl.ts b/packages/typegraph/src/backend/drizzle/ddl.ts index 5dffe3283..c96a445da 100644 --- a/packages/typegraph/src/backend/drizzle/ddl.ts +++ b/packages/typegraph/src/backend/drizzle/ddl.ts @@ -48,6 +48,18 @@ type CustomColumnType = Readonly<{ const EDGE_MATCH_IDENTITY_NAME_COLUMN = "match_identity_name"; const EDGE_MATCH_IDENTITY_KEY_COLUMN = "match_identity_key"; +/** + * The columns {@link planSqliteEdgeMatchIdentityAdoption} can `ADD`, in the + * order it adds them.

Measuring each entrypoint on its own refutes the type-surface explanation: the peak is the same wherever the rollup is rooted, including at `core` — a small barrel whose closure contains no query, store, merge or ontology surface at all — so no public type family drives it, and collapsing the deep conditional types on the query surface could not have moved the number. | `--dts-only` entry | Peak RSS | | --- | --- | | `src/backend/index.ts` | 9.33 GiB | | `src/index.ts` | 9.20 GiB | | `src/graph-merge/index.ts` | 8.85 GiB | | `src/core/index.ts` | 8.84 GiB | | `src/store/index.ts` | 8.76 GiB | | `src/query/index.ts` | 8.41 GiB | | `src/ontology/index.ts` | 8.30 GiB | | `src/provenance/index.ts` | 8.18 GiB | | `src/backend/drizzle/engine/index.ts` | 7.28 GiB | The cost is in how the declarations are produced, not in what they say. `dts: true` roots rollup-plugin-dts at `src`, and the plugin then builds a live TypeScript program and calls `program.emit()` once per module from inside the rollup transform hook, holding that per-module emit state for all 449 modules alongside the rollup module graph. TypeScript's own whole-program declaration emit over the same sources costs 1.53 GiB and 7 seconds, and rolling the entrypoints out of that emitted tree costs 0.46 GiB and 1 second — the plugin skips program creation entirely once its inputs are already `.d.ts`. So the build is now two ordered stages owned by `scripts/build.ts`: `tsc` emits the declarations once into a gitignored `.declaration-emit/`, then tsup bundles the JavaScript from `src` and rolls each entrypoint's declarations out of that emit. The rollup's entry list is derived from the same `entry` map the JavaScript build uses, so the two cannot name different roots, and the emit directory and heap ceiling have one spelling each in `scripts/declaration-emit.ts`. `pnpm dev` keeps both stages watching off a single compile: it runs `tsc --watch` alone, starts tsup once the declaration tree it waits on exists, and rollup then watches those emitted files, so a rewrite re-rolls the declarations. A watch session therefore survives a type error and recovers on the next save the way `tsc --watch` does, and it fails loudly if the watcher ever closes, since declarations would otherwise freeze at the last emit while the bundles kept refreshing. The pipeline refuses tsup's `--dts`, `--dts-only`, `--dts-resolve` and `--experimental-dts` flags rather than forwarding them, because each replaces the config's whole `dts` option and would silently re-root the rollup at source again. Peak for the complete build, JavaScript and declarations together, is now 1.48–1.54 GiB over consecutive runs, so the ceiling goes back to 8192 MiB with room to spare and #652's bump is reverted in both workflows. The published declarations are the same artifacts. Normalizing the content-hash suffixes in chunk names, 40 of 40 emitted chunks and 37 of 38 entry declarations are byte-identical to the old output; `interchange/index.d.ts` differs only in the member order of two `z.ZodEnum<{…}>` literals, which whole-program emit orders differently from per-file emit, and that ordering is the only API-report change this work causes. Shared declaration chunks are renamed cosmetically, from `foo-HASH.d.ts` to `foo.d-HASH.d.ts`, because the rollup now derives a chunk's basename from a `.d.ts` input rather than a `.ts` one. Nothing imports those names by hand: every entry declaration references its chunks through the rollup's own rewritten specifiers, the content hashes are unchanged, and `package.json#exports` points only at entry declarations. `experimentalDts` was measured and rejected on correctness rather than memory: it peaks at 2.97 GiB, but api-extractor aborts on the emitted tree with `Internal Error: Unable to follow symbol for "const"` and produces no declarations.

Each attaching item ran its own recursive-CTE acyclicity probe over the composition relation, and each one re-read both endpoint rows — the whole it attaches to and the part row the same frame had just inserted. A batch of N attaching items therefore paid N relation walks and 2N point reads on top of its own batched priming. The attach loop now reads every whole row once per kind through the batch point read's `getNodes` (deduplicated by `(kind, id)`, with a per-`(kind, id)` `getNode` fallback for a backend that lacks the port), judges each one through the same `assertCompositionWholeEndpointLive` owner the fenced attachment decision uses, and never reads a part row at all: the insert this frame just issued for it is the proof it is live, and `deleted_at` is the whole of that liveness question. What a preparation already holds about its endpoint rows travels as evidence — `"read"`, `"primedWhole"`, `"restoredByUpdate"` — rather than as a boolean that skips the reads, so each arm is bound to the proof that earned it. Acyclicity is probed once for the batch, after every composition edge it owes is inserted, through a new `assertPreparedEdgeCreatesAcyclic` seam beside the edge batch's existing post-insert probe (both now build their proposed edges from one `proposedRelationEdgeFromInsertParams`). This is the same order the edge `bulkCreate` path already uses, and for composition it is strictly more complete: a cycle that runs through two of the batch's own items cannot be seen by a probe that runs before the second item's edge exists. Each item's prepare-then-insert stays interleaved, because a later item's cardinality probe must see the rows the earlier items wrote. A cycle refusal still names a concrete offending edge. A self-attaching item is attributed to its own edge (the probe refuses a self-loop directly), and otherwise the refusal names the first of the batch's edges that lies on the cycle — which for a cycle spanning several items can be a different item than a per-item probe would have blamed. That attribution shift is the reason this was deferred from the branch's simplify pass, and it is now pinned by cross-backend tests that also assert no row of the refused batch survives. The composition cascade's soft path no longer re-reads its members. `planCompositionCascade` already reads every member's row to decide liveness, under the per-graph write lock the cascade holds, so that row IS the fenced pre-image; it now travels on the member and becomes `deleteNodeRowInFrame`'s `existing`. A second read under the same lock could only return the first. Leaf-first order, the consumed-edge cleanup, and the hook-free member semantics are unchanged. `CompositionExistenceError.code` is now per situation rather than `COMPOSITION_WHOLE_REQUIRED` for all four: a bare create, a refused detach, a contradicted whole and a contradicted `partOf.props` are four different things for a caller to handle, and a handler that routes on `code` alone could not tell them apart. One switch owns each situation's code, message and suggestion together, so a code can never drift from the message it is raised with; `details.situation` is unchanged and remains the discriminant for which optional detail fields are populated. This is a breaking change against the branch's earlier changeset text, and is listed as such. A second commit makes the cascade's reported order deterministic, which is where an intermittent failure of the composition lifecycle example led. The cascade reported its members in the order its whole-side edge read returned the rows, so `cascadedParts` on a receipt and on the delete's operation-hook context varied between runs whenever a whole owned more than one part — the row order follows the generated ids involved. That is nondeterministic output for every consumer, not only for the example, which failed in roughly half of the runs measured on the integration head as well as here. `planCompositionCascade` now collects the closure round by round and orders it through one owner, `cascadeDeletionOrder`: leaf-first as before, and within one level of the closure a deterministic order by kind, then id. Leaf-first is the part of the order that carries meaning, since a part's delete must run while its whole is still there; two sibling parts of one whole have no such relation, so they are sorted rather than left in read order. The comparator is the repo's lexicographic tuple compare, which is UTF-16 code-unit order; nothing compares this list against a SQL `ORDER BY`, so the cheaper comparator is the right one and the docs say "deterministic" rather than naming a collation the list does not promise. The cascade's consumed composition edge ids are sorted the same way before the cleanup delete, so the one-agreed-lock-order property covers edge rows as well as node rows. The same closure now reports the same list on every run and on every backend, so a consumer may compare `cascadedParts` for equality. The order is stated wherever `cascadedParts` is described — the receipt and hook-context types, the receipt guide, the limitations page, and the composition changeset — and the example asserts it exactly, with a sibling pair whose sort disagrees with its creation order. Two notes on what the tests can and cannot reach. The acyclicity probe's diagnostics name the batch shape that reached it, supplied by each executor rather than spelled once inside the shared attach loop; the returning shape reports `nodes.bulkCreate` and is also what the get-or-create batch legs reach. The no-return shape (`bulkInsert`) accepts no `partOf` at all, so it owes no attachment and its loop returns immediately — which is why the rollback guarantee, that a refused batch leaves no node row behind, is proven on the returning shape. The whole-row priming keeps a per-key `getNode` fallback for a backend without the batch point read, covered by a backend projected without `getNodes`: one successful two-item attach, and a missing whole refused with the identical `EndpointNotFoundError` on the identical endpoint side.

A get-or-create whose `ifExists: "update"` also runs ONE write plan: the attachment and the property update commit together in the ordinary case, so an update the row refuses (a unique conflict, a validation error) leaves ownership and history untouched instead of committing a move whose reason never applied. Every read the attachment owes — the fenced incumbent decision (a different held whole, the same whole through a different realizing edge, a stated `props` value the live edge disagrees with), the whole's liveness, and the realizing edge's own preparation (the part's liveness, cardinality, acyclicity, the required-existence rule) — runs before the update's first statement, so a refusal from any of them leaves the properties untouched too, including when the caller catches the refusal inside an enclosing `store.transaction(...)`, where there is no nested frame to roll back. The only attachment statement after the update is the edge insert itself, whose claim rows are the database backstop for verdicts the fenced reads already reached.

Deleting the *whole* still cascades to its required parts exactly as before — `existence: "required"` governs bare creation and detachment, not whole deletion.

Trusted import already refuses every declared composition pair regardless of `existence` (`composition_unsupported`), so there is no separate reason code for the required case. +`CompositionExistenceError.code` names the situation the refusal came from: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which of the optional detail fields are populated, so a handler may branch on either. + +A batch create whose items carry `partOf` now does per-batch work where it used to do per-item work, with the same refusals: the whole rows are read once per kind (one `getNodes` per distinct whole kind rather than a probe per item), a part row is never re-read after the insert that wrote it, and the acyclicity relation is walked ONCE over every composition edge the batch inserted instead of once per attaching item. The combined walk is what makes a cycle running through two of the batch's own items visible at all; a cycle refusal names a concrete offending edge — the self-attaching item's own edge for a self-loop, and otherwise the first of the batch's edges that lies on the cycle, which for a cycle spanning several items can be a different item than a per-item probe would have blamed. + `store.verifyConstraintFences()` gains a `compositionExistence` family, reporting any LIVE required-existence part with no live whole; a schema commit newly declaring `existence: "required"` on an already-populated pair runs the same check as a tightening preflight and refuses a dirty graph rather than silently admitting orphans. Graph merge's composition-orphan check gains a second arm for `existence: "required"`: alongside the existing check (a live part left behind when the merge deletes its whole node), it now also catches a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all, reported at plan time (`MergePlanCompositionOrphan.cause: "unattached"`) and refused at apply with the same `MergeCompositionOrphanError`. One residual gap remains: a composition edge silently dropped by canonicalization's own endpoint-deleted repointing, which issues no write for this (or any) per-write guard to see — run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](/limitations#composition-existence-existence-required). ### Breaking +- `CompositionExistenceError.code` is per situation (`COMPOSITION_WHOLE_REQUIRED`, `COMPOSITION_DETACH_REFUSED`, `COMPOSITION_WHOLE_CONFLICT`, `COMPOSITION_PROPS_CONFLICT`) rather than `COMPOSITION_WHOLE_REQUIRED` for every shape.

From a0eb3258952069de60da9029bb8105228c4b2823 Mon Sep 17 00:00:00 2001 From: Paul Dlug Date: Fri, 11 Sep 2026 03:24:11 -0700 Subject: [PATCH 036/255] fix(provenance): a belief-status close closes the required parts of the closed whole (#676) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `closeFactCurrency` closed a whole's belief status with no composition cascade, which left a required part attached to a whole whose currency had ended — a state the composition contract says cannot exist. The fix is in the support computation rather than in a cascade: a required composition part cannot exist without a live whole, so it is support-dependent on that whole. A required-part fact is supported only while the whole it currently hangs from is itself supported (a whole that is also a fact kind carries its own belief status) or is a live row (any other whole, including a plain node or a source). Closing a whole therefore closes its required parts in the same transition, and the affected walk carries those parts so the close and reopen passes reach them and the report names them. Reopen needs no new machinery and gets none: it is driven by support exactly as before, so a part comes back when the whole is supported again AND its own justification still fires. There is no ledger of what a close closed, which is what keeps a close and a reopen exact inverses of each other. A required part is closed even when a different source supports it, because the existence dependency dominates its own grounding. An optional part is untouched — it can exist with no whole, so it keeps both its attachment to the closed whole and its belief status, and the composition claim still stops a second whole from taking it. Each closed fact fires its own `delete` operation hook, parts included, rather than folding into one event the way the delete cascade does: every part reaching the close is a fact of its own, closed by its own support verdict. `RetractionReport.died` now names every fact a transition closes. It used to be re-derived over what was believed beforehand, which left one silent case: a fact found live but already unsupported when the transition reached it was tombstoned by the close pass and named nowhere. The rows a transition closes are resolved once by one owner and handed to both consumers — the pass that writes the tombstones and the report that names them — so an unnamed close is unreachable by construction rather than by two filters agreeing. Only writes outside the store's own paths produce that state, and `store.verifyConstraintFences()` reports it while it lasts. A non-fact whole's liveness is the one owner's verdict — present and not tombstoned, the rule the write path's whole-endpoint refusal applies — and deliberately not a validity-window question. A whole whose window has closed is still a row the write path would accept as a whole, so treating it as dead would leave a part unbelieved before a transition and tombstoned by one. `store.verifyConstraintFences()`' `compositionExistence` family now requires the whole endpoint to be a live row as well, so a live required part left hanging from a TOMBSTONED whole is reported rather than passing as attached — a state the delete cascade cannot produce but a direct backend write, a custom port, or a bypassed import can. The write path's own incumbent decision is deliberately narrower and unchanged: a tombstoned whole still holds its part's attachment there, so a second whole cannot quietly take it, and a case pins that split in both directions. Provenance and the audit share one page-scoped attachment owner, so the "batched candidate read, per-row confirmation for a negative" shape is spelled once, and one liveness owner for the wholes a page names; each page reads its wholes once per kind through the batch point read, falling back to the per-id read that bundle declares. The verdict those reads go through is the store's own, minted once at construction and threaded through the runtime port and the audit context rather than re-resolved, then bound per read against the object the read actually runs on. `createRetractionCapability` refuses a configuration whose fact kinds own required parts it cannot reach: a fact kind that is the whole of an `existence: "required"` pair whose part kind is not itself a fact kind throws `ConfigurationError` (`PROVENANCE_REQUIRED_PART_NOT_A_FACT`). Closing such a whole would leave a live required part hanging from it and no transition could repair that, so the hole is refused where the graph's author can fix it. Both sides are read through subsumption.

The plan's normalized write view is now `resolvedMergeWrites(plan)`, the exact `MergePlanWrites` shape the artifact serializes, and one walk over that view serves the live-plan apply, the plan-time preview, and the replayed-artifact apply alike. A new source is added in one place. The artifact builder derives its `writes` and `proposed` counts from the same projection, so the two commit paths can no longer read two projections of one plan. The interchange write path's post-retraction aftermath (`applyIdentityChangesForContext`) and its assert-effect block (`importIdentityAssertionsIntoTarget`) now route through the owners the simplify pass created, `applyRetractionAftermath` and `applyPairRelationEffect`, instead of carrying their own copies; `mergeCurrentClasses` is no longer exported since that was its last outside caller. `IdentityReconciliationOptions` gains `onEdgeConflict: "repoint" | "flag"` (default `"repoint"`) and `onUniquenessConflict: "refuse" | "flag"` (default `"refuse"`). The defaults are today's behavior byte for byte: no edge collision is computed under `"repoint"`, and no plan-time probe runs under `"refuse"`. `IdentityUnresolvedConflict` gains the ruled arms. `kind: "edge"` names the edge kind, the two pre-repoint endpoints whose pairing collapsed distinct relationships onto one slot, the survivor they fused into, the endpoint side, the colliding edge ids, the dropped assertions and their branches. `kind: "uniqueness"` names the constraint and fields, the fused canonical entity, the key's current holder (another write of the plan or a committed row, reported under its own kind), the fused members, and the dropped assertions and branches. The plan artifact's strict `review.identityConflicts` schema admits both. The edge-repoint step returns the decision rather than a flag a caller re-derives: `EdgeRepointResult.collapsed` lists every fold set whose rows named two or more distinct pre-repoint pairs, with the survivor, the canonical endpoints and each row's pre-repoint keys. Ordinary multigraph multiplicity is never reported there. The rebuild is one deterministic pass. Candidate generation is split into `proposeCandidates` (sources, base lookups, embeddings, run once) and `scoreProposals` (pure, re-runnable with a set of excluded identity assertions). The resolver builds the plan, collects the pairing-induced conflicts a `"flag"` policy owns (an identity-paired cluster whose fold collapsed distinct relationships, or whose fused write set the store's uniqueness decision refuses), rebuilds once with the assertions behind those pairings excluded, and carries the dropped conflicts on `MergeReport.identityConflicts`. The first pass is deliberately over-inclusive and the rebuild is the ground truth: a pair the rebuilt plan fused anyway (similarity, a shared unique value, a retype) was never held together by the pairing, so its collision is the merge's ordinary behavior and is not reported against it. One rebuild converges because removing candidate edges only reduces fusions and a conflicted cluster loses every identity edge it had; a second pass still reporting a pairing-induced conflict refuses with a typed `MergeError` rather than looping. Dropping a pairing drops only its use as a candidate: the assertion still lands in the identity ledger, so the rows stay in one identity class without being consolidated into one row by this merge. Uniqueness detection never re-spells key, scope, filter or collation semantics in the planner. `findResolvedNodeClaimConflicts` (store/claims/resolved-node-claims.ts) is the one finding function over a resolved write set, in-set competitions first and persisted holders second; the write path's `validateResolvedNodeClaims` throws its first entry, and the store exposes the findings to the planner as the `probeResolvedNodeUniqueness` runtime-port member, prepared by the same constraint-attachment helper `applyResolvedNodeUniqueness` uses, over the same after-images and releases the commit applies (`plannedNodeUpserts`, one owner for both). A backend that cannot serve the batched probe refuses the stated `"flag"` as an invalid option naming `identity.onUniquenessConflict`. A collision a member carries on its own, rather than one the fusion created, stays where it is today: the commit's authoritative refusal. The `id-reuse` conflict reason the issue names had already been removed from the union, the schema, the docs and the changesets on this branch; one-id-one-truth is a thrown `IdentityMergeConflictError`, not a reason. Nothing further ships for it. While wiring the sibling refusal, the `identity.pairing` storage-missing translation was found comparing the refusal code against the error class code (`ConfigurationError.code` is always `CONFIGURATION_ERROR`), so it could never fire; it now reads `details.code`, as the code is carried. The graph-merge guide's identity-conflicts section documents both knobs, what `"flag"` drops and keeps, and the two arms; the identity-reconciliation changeset lists the fifth-arm shape change under Breaking.

That validation runs on every call that states `props`, including a `getOrCreateByConstraint`/`reparent` call that resolves to an attachment already holding: those write no edge, but still refuse a schema-invalid value, and still refuse (`CompositionExistenceError`, `situation: "props"`) a valid value that differs from the edge's live stored props rather than silently keeping the old one. `resolveCompositionAttachment` is the one owner of both refusals; `KindRegistry.getCompositionEdge`'s silent first-match resolution is gone. - -**`nodes..reparent(id, attachment)` moves a part to a new whole.** Neither half of a move is legal on its own — the new attachment refuses while the old edge holds the part's one-whole claim, and `existence: "required"` refuses the detach while the part is live — so a caller had no legal order to write. `reparent` performs both under one per-graph fence, in one transaction, and validates the FINAL state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties, and every descendant beneath it. Every read the new attachment owes — cardinality at the new whole (counted as the insert will see it, with the retiring edge already excluded), acyclicity, the realizing edge's props — runs before the old attachment is retired, so a refused move leaves the part attached where it was, including for a caller that catches the refusal inside an enclosing `store.transaction(...)`. How the old attachment retires follows its declared population: a `population: "one"` edge is deleted, removing the attachment from every `store.asOf(t)` read at every coordinate before the move (a `one` binding persists for the row's whole life, so an ended row would still read as an attachment); a `population: "oneActive"` edge instead has its window ended at the move instant, leaving the previous membership readable as valid-time history. The population comes from the INCUMBENT row's own pair, resolved through the realizing edge that holds the attachment. The move instant is read ONCE and is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none shows it with two. Reparenting to the whole the part already holds is accepted as a no-op — no write, no history — though a stated `props` is still checked: valid and value-identical to the edge's live stored props, the no-op stands, and a valid but different value refuses (`situation: "props"`) rather than being silently dropped. - -**`partOf` on `getOrCreateByConstraint` is now a POSTCONDITION, not a create-only option.** When the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies it — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`situation: "props"`) rather than silently kept, since a satisfied match writes no edge. A node with no live whole has the attachment written now, whatever its pair's declared `existence`; a node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused with `CompositionExistenceError` (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. This reverses the previous unconditional refusal, which made a re-run of the same get-or-create fail purely because it was a re-run. - -Which of those three dispositions applies is decided under the per-graph write fence, from the incumbent re-read there — never from a lock-free read. `reparent` and the get-or-create postcondition are one write plan that takes an explicit incumbent disposition: `reparent` states "replace" (moving a part is what it is for), every get-or-create path states "refuse". So two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError` — never a silent move, whatever order their lookups observed. A get-or-create whose `ifExists: "update"` also runs ONE write plan: the attachment and the property update commit together in the ordinary case, so an update the row refuses (a unique conflict, a validation error) leaves ownership and history untouched instead of committing a move whose reason never applied. Every read the attachment owes — the fenced incumbent decision (a different held whole, the same whole through a different realizing edge, a stated `props` value the live edge disagrees with), the whole's liveness, and the realizing edge's own preparation (the part's liveness, cardinality, acyclicity, the required-existence rule) — runs before the update's first statement, so a refusal from any of them leaves the properties untouched too, including when the caller catches the refusal inside an enclosing `store.transaction(...)`, where there is no nested frame to roll back. The only attachment statement after the update is the edge insert itself, whose claim rows are the database backstop for verdicts the fenced reads already reached. An already-satisfied call with no update to make stays read-only, restating the realizing edge's `props` included: agreeing props are part of what "already satisfied" means, so an idempotent ingest does not take the per-graph write fence to be told it has nothing to write. - -**A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts` — `{ kind, id }` refs taken from the plan the cascade executed, so they never name a part the cascade did not delete — in the cascade's own delete order: leaf-first (every part before the whole it belongs to), then ordered deterministically by kind, then id, within one level of the closure. Two sibling parts of one whole have no order between them to respect, so they are sorted rather than left in the order the cascade's reads returned them: the same closure reports the same list on every run and on every backend, which is what lets a consumer compare `cascadedParts` for equality, and two concurrent cascades over overlapping closures take their row locks in one agreed order. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order; the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, alongside the transaction's own receipt, attributed the same way its write counters are — by the context the write ran through, not by timing, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them (the cascade has not been planned yet), and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. - -**`subgraph({ composition: true })` returns the COMPLETE owned unit.** The composition closure is bounded by its visited set, never by `maxDepth`: a part tree deeper than the default depth comes back whole, because a whole plus a truncated prefix of its parts is not an export unit. It is a set-semantics (`UNION`) recursion over an `(id, kind)` frontier — the same device that makes the composition-union acyclicity probe exhaustive — so it reaches a fixpoint with no hop ceiling at all: the engine's 1000-hop cap on an explicit traversal does not apply to it, and a part chain longer than that is no longer silently truncated. Delivered or refused, never partial, against the engine as well: a closure statement the database cut short (a `statement_timeout`, a cancelled query) refuses with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) naming the root, through the same cut-short classification the acyclicity probe uses, rather than returning the rows it reached. `maxDepth` and `cyclePolicy` continue to bound the explicit `edges` traversal alone. - -The ontology, errors, and limitations pages are rewritten to state what composition enforces today — one whole per part across every relation and both orientations, leaf-first cascade, acyclicity over the oriented composition union at write time, and `existence: "required"` — replacing the "planned for tier 1" and "forthcoming claim provisioning" language those pages still carried. - -### Breaking - -- `KindRegistry.getCompositionEdge(partKind, wholeKind)` is removed. Use `compositionPairsBetween(partKind, wholeKind)` (every declared pair, code-point ordered by realizing edge kind) or `compositionPairVia(partKind, wholeKind, viaEdgeKind)` (the pair a known realizing edge holds).

Every fused/read-free node-create and edge-delete program declines a required-existence kind (or any input carrying `partOf`), so a required-existence bulk create or delete always takes the portable, fully-validated path. - -Ending, soft-deleting, or hard-deleting a required-existence part's composition edge while the part is LIVE is refused with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); a part that is already retired is not orphaned by losing its edge, so detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts exactly as before — `existence: "required"` governs bare creation and detachment, not whole deletion. - -Validating import tracks every required-existence part it creates and, once the whole payload's node and edge sets are both known, accepts one already attached in the same batch or already live on the target and reports a per-row error (removing the orphaned node row in the same transaction) for anything still unattached — the rest of the import commits. Trusted import already refuses every declared composition pair regardless of `existence` (`composition_unsupported`), so there is no separate reason code for the required case. - -`CompositionExistenceError.code` names the situation the refusal came from: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which of the optional detail fields are populated, so a handler may branch on either. - -A batch create whose items carry `partOf` now does per-batch work where it used to do per-item work, with the same refusals: the whole rows are read once per kind (one `getNodes` per distinct whole kind rather than a probe per item), a part row is never re-read after the insert that wrote it, and the acyclicity relation is walked ONCE over every composition edge the batch inserted instead of once per attaching item. The combined walk is what makes a cycle running through two of the batch's own items visible at all; a cycle refusal names a concrete offending edge — the self-attaching item's own edge for a self-loop, and otherwise the first of the batch's edges that lies on the cycle, which for a cycle spanning several items can be a different item than a per-item probe would have blamed. - -`store.verifyConstraintFences()` gains a `compositionExistence` family, reporting any LIVE required-existence part with no live whole; a schema commit newly declaring `existence: "required"` on an already-populated pair runs the same check as a tightening preflight and refuses a dirty graph rather than silently admitting orphans. - -Graph merge's composition-orphan check gains a second arm for `existence: "required"`: alongside the existing check (a live part left behind when the merge deletes its whole node), it now also catches a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all, reported at plan time (`MergePlanCompositionOrphan.cause: "unattached"`) and refused at apply with the same `MergeCompositionOrphanError`. One residual gap remains: a composition edge silently dropped by canonicalization's own endpoint-deleted repointing, which issues no write for this (or any) per-write guard to see — run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](/limitations#composition-existence-existence-required). - -### Breaking - -- `CompositionExistenceError.code` is per situation (`COMPOSITION_WHOLE_REQUIRED`, `COMPOSITION_DETACH_REFUSED`, `COMPOSITION_WHOLE_CONFLICT`, `COMPOSITION_PROPS_CONFLICT`) rather than `COMPOSITION_WHOLE_REQUIRED` for every shape.

Direction is derived per realizing edge kind rather than fixed: a `part -> whole` edge is followed reversed and a `whole -> part` (`has_*`) edge is followed in its own direction, and a relation realized by both orientations across levels compiles to one traversal step whose direct and inverse edge-kind sets union via the existing `inverseEdgeKinds` mechanism — a mixed relation costs nothing extra to declare, and the common uniform-orientation case pays nothing extra to compile. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the parts/wholes closure under a kind is registry data that may span more than one node kind with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows; `expand` is not accepted on either step. - -`SubgraphOptions` gains `composition?: boolean`: closes the selected root over `compositionEdgeKindsUnder` its actual kind before the existing projection runs, in addition to whatever `edges` already lists — the whole-plus-parts export unit. This is set-level: a root kind declaring no composition parts contributes nothing and the read still runs; a graph declaring no composition relation at all refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED`). Because which composition edge kinds join depends on the root's runtime kind, `composition: true` widens the result's edge-key type to the graph's whole edge-kind union (the new `SubgraphResultEdgeKinds`), so every key the traversal can put in `adjacency` / `reverseAdjacency` is reachable through the result type; `composition` absent or `false` keeps the existing `edges`-list typing unchanged. The `project.edges` keys a call may name widen with the result (`SubgraphProjectFor`), so a `composition: true` read can project the composition edges it receives; an edge kind outside `edges` is still refused without it. The closure itself is exhaustive: it is a set-semantics recursive walk over `(id, kind)` with no hop ceiling, so a unit of any depth comes back whole, and `maxDepth` / `cyclePolicy` bound only the `edges` traversal listed alongside it. An engine that cuts the closure statement short (a statement timeout, a cancelled query) is refused with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) rather than returning a partial unit. - -`TraversalBuilder` gains `toKindSet(kinds, alias)`, a general-purpose finalizer (parallel to `to()`/`toDynamic()`) for an explicit, already-resolved set of target node kinds rather than one compile-time-known or runtime-resolved kind — what `parts()`/`wholes()` need and any future caller with the same shape of problem can reuse. - -### Fixes - -A recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set (`{ expand: "inverse" }`, or the mixed-orientation case `parts()`/`wholes()` now exercise) compiled its recursive term as two branches, each independently self-joining the recursive CTE, unioned with `UNION ALL`. PostgreSQL refuses this — a recursive CTE's self-reference may appear at most once in its recursive term, even split across `UNION ALL` arms — while SQLite's looser recursive-CTE implementation accepted it, so the defect was invisible until run against a real PostgreSQL engine. Both edge orientations are now normalized into one relation, computed once before recursion starts, so the recursive term joins the recursive CTE exactly once on every dialect. diff --git a/.changeset/composition-relation.md b/.changeset/composition-relation.md deleted file mode 100644 index 9032ccade..000000000 --- a/.changeset/composition-relation.md +++ /dev/null @@ -1,18 +0,0 @@ ---- -"@nicia-ai/typegraph": minor ---- - -`partOf` and `hasPart` are now a real [composition](https://typegraph.dev/ontology#composition) relation, realized by an edge kind that stores the containment. `partOf(part, whole, { via, partSide? })` and its mirror `hasPart(whole, part, { via, partSide? })` name that edge with `via`; orientation is inferred from the declared pair against the edge's endpoints, and when both orientations are admissible (a same-kind containment edge) the declaration names `partSide: "from" | "to"`.

Two declarations disagreeing on `existence` for one part kind refuse at registry build with `ONTOLOGY_COMPOSITION_EXISTENCE_MIXED`. `existence` is emitted only when `"required"`, so an explicit `"optional"` serializes byte-identically to omitting it and an untouched graph's schema hash is unchanged. + +**A part names the edge that realizes its attachment.** `NodeCollection.create`'s options are extracted into `NodeCreateOptions`, and `partOf` — on `create`, `bulkCreate`'s per-item options and both get-or-create entries — is a `CompositionAttachment`, `{ kind, id, via?, props? }`, written in the same write as the node: a dead or missing whole, an undeclared pair, or a lost composition claim aborts the node create too, leaving no orphan row. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written; `partOf` is honored on an optional-existence pair too. A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. + +**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. + +**`nodes..reparent(id, attachment)` moves a part to a new whole**, which no sequence of detach and attach could express. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. Reparenting to the whole the part already holds is a no-op, no write and no history, though a stated `props` is still checked: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). + +**Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts — `existence: "required"` governs bare creation and detachment, not whole deletion. `CompositionExistenceError.code` names the situation: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which optional detail fields are populated, so a handler may branch on either. + +**Deleting a composition whole cascades leaf-first through its live parts closure**, each part running through its own node-delete pipeline inside the whole's transaction, with restrict and cascade `onDelete` behaviors on non-composition edges honored per part. Composition edges never count as a `restrict` obstacle on either end. An instance-level cycle among reflexive composition edges is refused with `CompositionCycleError` (`COMPOSITION_CYCLE_DETECTED`) rather than looping or truncating. Resurrecting a soft-deleted whole restores the whole alone, ending a whole's validity window is not a cascade, and the cascade emits one operation-hook event, for the whole. See [Composition Cascade](https://typegraph.dev/limitations#composition-cascade). `NodeDeletePolicy` gains `consumedEdgeIds` (connected edges the cascade has already consumed, filtered out before the kind's `onDelete` behavior applies) and `cascadeComposition`. + +**A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts`, `{ kind, id }` refs that never name a part the cascade did not delete, in the cascade's own delete order: leaf-first, then by kind, then id, within one level of the closure. That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order, and the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them, and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent. There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`. + +**`QueryBuilder` gains `parts()` and `wholes()`**, declared-structure sugar over the recursive `Traversal` AST for a declared composition relation. `parts("alias", { from?, maxHops?, depth?, path? })` derives the edge kind(s) and direction(s) from the registry's composition relation and recurses to the full transitive closure by default; pass `maxHops: 1` for the direct level only. `wholes()` is the mirror, returning the ancestor chain. Direction is derived per realizing edge kind: a `part -> whole` edge is followed reversed, a `whole -> part` (`has_*`) edge in its own direction, and a relation realized by both orientations across levels compiles to one traversal step. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the closure under a kind may span several node kinds with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows, and `expand` is not accepted on either step. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()`/`toDynamic()` for an explicit, already-resolved set of target node kinds. + +A related defect is fixed: a recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set (`{ expand: "inverse" }`, or the mixed-orientation case `parts()`/`wholes()` now exercise) emitted SQL that PostgreSQL rejected and SQLite accepted.

A root kind declaring no composition parts contributes nothing and the read still runs; a graph declaring no composition relation at all refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED`). Because which composition edge kinds join depends on the root's runtime kind, `composition: true` widens the result's edge-key type to the graph's whole edge-kind union (the new `SubgraphResultEdgeKinds`), so every key the traversal can put in `adjacency` / `reverseAdjacency` is reachable through the result type; `composition` absent or `false` keeps the existing `edges`-list typing unchanged. The `project.edges` keys a call may name widen with the result (`SubgraphProjectFor`), so a `composition: true` read can project the composition edges it receives; an edge kind outside `edges` is still refused without it. The closure is exhaustive, bounded neither by `maxDepth` nor by the engine's 1000-hop cap on explicit traversals, so a part chain of any depth comes back whole rather than truncated, and `maxDepth` / `cyclePolicy` bound only the `edges` traversal listed alongside it. It is delivered or refused, never partial: a closure statement the database cut short (a `statement_timeout`, a cancelled query) refuses with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) naming the root. + +**A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch inserted — which is what makes a cycle running through two of the batch's own items visible at all. A cycle refusal names a concrete offending edge: the self-attaching item's own edge for a self-loop, otherwise the first of the batch's edges lying on the cycle. + +**Import, the audit and graph merge all see composition.** Validating import tracks every required-existence part it creates and, once the payload's node and edge sets are both known, accepts one already attached in the same batch or already live on the target and reports a per-row error — removing the orphaned node row in the same transaction — for anything still unattached; the rest of the import commits. Trusted import refuses every declared composition pair regardless of `existence` (`composition_unsupported`). `store.verifyConstraintFences()` gains a `compositionExistence` family reporting any live required-existence part with no live whole, and a `composition` family reporting two or more live edges holding one part's reserved composition axis; a schema commit newly declaring `existence: "required"` on an already-populated pair runs a tightening preflight and refuses a dirty graph rather than silently admitting orphans. `planMerge` and `planMergeIncremental` report composition orphans in `MergePlanReview.compositionOrphans` under two causes: a part attached on the target to a whole the branch deletes (`cause: "deleted"`), and a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all (`cause: "unattached"`). `applyMergePlan` re-verifies both inside the apply transaction and refuses with `MergeCompositionOrphanError` (`MERGE_COMPOSITION_ORPHAN`), and merge apply deletes nodes with `cascadeComposition: false` so the plan stays the authority over what apply deletes. One residual gap remains: a composition edge dropped by canonicalization's own endpoint-deleted repointing issues no write for any per-write guard to see, so run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](https://typegraph.dev/limitations#composition-existence-existence-required). + +### Breaking + +- `partOf` / `hasPart` require `via`, in a third options argument.

A failing pair is refused at compile time with a named `StructuralSubtypeMismatch` object naming the offending fields, and at registry build — live graphs, `evolve()`-authored extensions and deserialized documents alike — with a `ConfigurationError` under one of four codes (`ONTOLOGY_SUBCLASS_NOT_STRUCTURAL_SUBTYPE`, `ONTOLOGY_SUBCLASS_SCHEMA_INCOMPARABLE`, `ONTOLOGY_EQUIVALENCE_NOT_STRUCTURAL_SUBTYPE`, `ONTOLOGY_EQUIVALENCE_SCHEMA_INCOMPARABLE`) naming the child, the parent, whether the pair was declared or reached transitively, and the full violation list. `getSchemaChanges` reports the same refusal before an upgrade, including when a migration only edits a property schema on a kind already party to an existing hierarchy; `requiresMigration` collapses it to `true` by design, so call `getSchemaChanges` directly for the detail.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair. Subsumption stays strict — a kind is never its own subclass, and `expandSubClasses` still lists each kind once. External IRIs stay out of subsumption: they are inert references, so `Person ≡ schema:Person ≡ Individual` folds `Person` and `Individual` together without making the IRI a kind. `reconcileTypes` now reads the store's own validated `KindRegistry`, so a merge and a query can no longer disagree about which kinds are the same class, and every kind-name ordering in that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI; an equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. -An alias states its expansion as ONE option, `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`), on `from()`/`to()`/`fromDynamic()`/`toDynamic()`. `"narrower"` expands a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf` — the alias type is untyped, since no schema relationship is claimed. Because it is one value, an alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Omitting the options argument, passing `{}`, and passing an explicit `undefined` all mean "take the store default", so an options bag can be forwarded through a caller's own helper without special-casing the empty case. A bag that can carry an axis the call site does not pin — `{ expansion?: "exact" }` from a wrapper that only ever narrows, or the option type itself — forwards as well, and types its alias conservatively (untyped, as `"narrower"` does), since the axis is unknown at compile time. `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` for the same forwarding reason. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"` — the search facade is not polymorphic by default). +**`from()`/`to()`/`fromDynamic()`/`toDynamic()` are polymorphic by default**: a query against a supertype returns its subtype rows, typed with the parent's properties, and the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect. `queryDefaults.expansion: "exact"` on `createStore(...)` restores the previous exact-kind behavior everywhere in one place; `search()` and the collection APIs (`find`, `count`, `updateWhere`, `compareAndSet`) are unaffected and stay exact-kind. -Every meta-edge factory — not only `subClassOf`/`equivalentTo` — now returns a relation typed with its meta-edge name literal and its endpoint kinds, the IRI overload (`equivalentTo(Kind, iri)`, typed `from: Kind, to: string`) included. A kind whose only equivalence is IRI-routed therefore widens its alias like any other equivalenced kind, and a graph whose ontology mixes `subClassOf` with `broader` / `inverseOf` / `disjointWith` keeps exact alias types for the kinds no subsumption relation names. The flip side: a relation a caller annotates as the bare `OntologyRelation` has lost the literals the alias computation reads, so it now widens EVERY alias in that graph conservatively rather than reporting an affected kind as unaffected. An endpoint declared as a union of node types keeps its literals and stays precise — it widens exactly the kinds the union can hold, and nothing else. +**An alias states its expansion as one option**, `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`), on `from()`/`to()`/`fromDynamic()`/`toDynamic()`. `"narrower"` expands a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf`, and types the alias untyped since no schema relationship is claimed.

A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`).

Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair.

The upfront archival-restore guard in import now gates on TypeGraph capture like the store's backstop, so an engine-native target refuses before any node is written instead of after the stream's entity sections. --- apps/docs/src/content/docs/errors.md | 7 ++ apps/docs/src/content/docs/identity.md | 4 +- packages/typegraph/src/errors/index.ts | 4 + packages/typegraph/src/identity/replay.ts | 11 +-- .../typegraph/src/identity/service-types.ts | 4 + .../typegraph/src/identity/transition-log.ts | 52 +++++++++--- packages/typegraph/src/interchange/import.ts | 18 ++-- packages/typegraph/src/store/store.ts | 8 +- .../tests/engine-native-recorded-time.test.ts | 83 ++++++++++++++++++- .../identity-transition-log-ratchet.test.ts | 2 +- 10 files changed, 162 insertions(+), 31 deletions(-) diff --git a/apps/docs/src/content/docs/errors.md b/apps/docs/src/content/docs/errors.md index 3a595ef31..dd218bcf9 100644 --- a/apps/docs/src/content/docs/errors.md +++ b/apps/docs/src/content/docs/errors.md @@ -329,6 +329,12 @@ cannot answer a request.

The bump is one-way and deployment-visible: a database stamped 3 is caught up in place by the next privileged open (`createStoreWithSchema` / `createAdapterStoreWithSchema`) or an explicit `backend.adoptBaseSchema()`, and until one of those runs, a DML-only or zero-DDL runtime (`createVerifiedStore`, graph-template attach) refuses with `BaseSchemaMigrationError`, so privileged adoption must finish before those workers start.

These +// helpers are implementation details behind the exported fluent surface; no +// forgotten name was removed, and exporting them would add API without an +// independent caller contract. +// Phase 4 adds eleven internal relation contract names behind the root's public +// fluent API: AggregateRelationFields, CompatibleRelationProjection, +// DerivedRelation, RelationAst, RelationColumn, RelationDefinition, RelationOrder, +// RelationProvenance, RelationSource, RelationState, and SetRelation.

The root +// directly exports its caller-facing `CollectOrder` type. The six secondary +// Store-bearing entrypoints render that type through the same expression +// surface without re-exporting it, so each gains `CollectOrder` instead (+1). +// No other forgotten-export set changes: the aggregate AST metadata and +// collection element metadata reuse types already present in those graphs. +// Splitting collection aggregation into its own public AST discriminant adds +// the internal `CollectExpressionNode` to the root and the same six +// Store-bearing secondary entrypoints (+1 each). `CollectOptions` is exported +// directly at the root and does not propagate into the secondary declaration +// graphs. Removing `"collect"` from `AggregateOperator` and `orderBy` from +// `AggregateExpressionNode` changes existing declarations without changing +// the forgotten-name set. No other entrypoint changes. +// Recorded revision requests add three public root types: +// `RecordedRevisionRequest`, `HistoryTransactionContext`, and +// `MeasurableHistoryTransactionContext`. The Store-bearing `./provenance`, +// `./sqlite/local`, and `./postgres/pglite` entrypoints render those root-only +// types transitively, so each gains exactly those three forgotten exports. +// The root names all three directly and gains no forgotten-export debt. +// Explicit multi-kind sources add FieldCategory to the root's reachable helper +// graph. Store-bearing secondary entrypoints also reference CommonPropertyKeys +// and NodePropsFor, which are exported by the root rather than repeated on each +// secondary surface. IsUnion is now shared with expression subqueries and keeps +// its existing forgotten-export name. Measured additions: +1 root, +3 on the +// six Store-bearing secondary entrypoints below; other surfaces are unchanged. +// Adopted schema evolution adds directly exported plan, option, outcome, and +// timeout types at their defining barrels. The API extractor also renders +// implementation-only owner/payload and backend adoption types transitively +// through Store and adapter signatures. These are booked as forgotten-export +// debt rather than widened as standalone package exports: they are not +// callable entrypoints or useful authoring contracts. After the six public +// plan/option types are directly exported from the root, root debt rises by +// four; +// Store-bearing secondary surfaces rise by six; backend adapter surfaces rise +// by two (one for the adoption result), and schema/engine surfaces by one. +// `branchForEvolution` is a direct graph-merge export; its transitive +// `EvolutionPlan` and Store evolution option types account for the additional +// graph-merge debt. The exact fingerprints below gate every changed surface. +// Planned evolution (#705) changes the type graph reachable through StoreEvolution: +// SchemaIdentity and the discriminated EvolutionRequirement union become named +// root/schema exports, while adapter authoring gains SchemaProvisioning and +// AdoptedSchemaWriteTransaction. The remaining entrypoint-specific changes below +// are exact symbol-set fingerprints, not a relaxed count-only allowance. +// Ordered record collections export CollectRecordFields, CollectedRecord, and +// CollectRecordOperand directly from the root. Six Store-bearing secondary +// entrypoints reach only CollectRecordOperand transitively, adding exactly +// that one forgotten name to each fingerprint below. Removing that name from +// each measured symbol set reproduces its previous fingerprint. +// Partitioned top-N introduces TopPerPartitionRelation as a transitive +// forgotten export at the root. Six Store-bearing secondary entrypoints also +// reach TopPerPartitionOptions and TopPerPartitionOrder without exporting them +// directly. Removing these exact new names from each measured symbol set +// reproduces its previous fingerprint; all other entrypoints are unchanged. +// Shared capability upgrades add ContributionScope and node-candidate query +// contracts to Store-bearing entrypoints, while endpoint-set conformance adds +// its fixture types and a bundle-member helper. These declarations are +// intentionally public or transitively reachable from public signatures; the +// updated hashes below record the exact measured name sets from this run. +// Array membership and tuple cursor predicates add their AST nodes to the +// public query graph. The root also reaches their operand helper types; each +// Store-bearing secondary entrypoint reaches the two predicate node types. +// Resolved node update batch contracts become reachable through the six +// Store-bearing secondary entrypoints. The fingerprints below record the +// complete measured symbol sets after that portable batch surface was added. +// Recorded heterogeneous node upserts add the public transaction input/result +// types at the root and make the backend lowering contracts reachable through +// GraphBackend.

A store open with `history: true` on an engine-native backend no longer binds TypeGraph capture to its schema commit. diff --git a/packages/typegraph/src/backend/capabilities/recorded-time-ownership.ts b/packages/typegraph/src/backend/capabilities/recorded-time-ownership.ts index c5a3cad4c..c5fd604d0 100644 --- a/packages/typegraph/src/backend/capabilities/recorded-time-ownership.ts +++ b/packages/typegraph/src/backend/capabilities/recorded-time-ownership.ts @@ -32,6 +32,23 @@ export function resolveRecordedTimeOwnership( : "engine-native"; } +/** + * Whether TypeGraph itself captures recorded history for a store over + * `backend` that requested `history`: only under TypeGraph-owned recorded + * time.

A backend implementing `readConstraintFenceViolations` may receive an `edgeEndpointAllowances` declaration and must answer with `misassignedEdgeEndpointRows`; omitting the key when the family was requested is refused with `CONSTRAINT_FENCE_AUDIT_FAMILY_UNSUPPORTED` rather than reported as a clean result. A backend that cannot commit a preflight atomically refuses a tightening with `ONTOLOGY_TIGHTENING_REQUIRES_ATOMIC_BACKEND`, and a preflight target that cannot run the audit refuses with the existing `CONSTRAINT_FENCE_AUDIT_UNSUPPORTED`. One residual window remains: a writer that commits under the previous schema version between the probe and the version compare-and-set is not seen, so `store.verifyConstraintFences()` remains the post-hoc detector. **An ontology a diff cannot validate is now a refusal rather than a silent classification.** `classifyOntologyChanges` and `computeSchemaDiff` propagate `ConfigurationError` when a diff adds or removes an ontology relation and either side's stored or proposed ontology cannot be validated. This is new behavior for the stored side of the diff: nothing previously validated a persisted schema document's registry, so a document persisted under an older, laxer validator can surface this refusal the first time a relation-touching commit is attempted against it — including a fix-forward migration whose whole point is to remove the offending relation. There is no workaround for that case in this release; repair such a document through a path that does not diff ontology relations first. Every read-only caller built on `computeSchemaDiff` inherits this: `loadAndVerifyGraph` (and so `createVerifiedStore` / `assertSchemaCurrent`) and `getSchemaChanges()` now also throw `ConfigurationError` for the same documents. `requiresMigration()` is the one exception: it treats "cannot classify" the same as "needs migration" and returns `true` instead of throwing, so a document only the privileged path can interpret still routes there. +**Adopted evolutions and rollbacks run the same tightening preflight.** `planEvolution()` derives the tightening check from the plan's own before/after documents and lists it as an `ontology-tightening` requirement, naming the probed ontology `changes` and the newly constrained `edgeCardinalityAxes`; `withEvolvedTransaction()` runs it on the fenced caller session before the schema compare-and-swap and refuses with the same `MigrationError` `Store.evolve()` raises, so a `disjointWith`, `acyclic: true` or tighter cardinality that existing rows violate can no longer be published through a plan. `rollbackSchema()` checks the version it reactivates against the active one the same way — a rollback to a stricter version whose declarations live rows violate is refused, while a rollback that tightens nothing still flips on any backend — and refuses to reactivate a version that re-keys a populated edge kind's match identity (`reason: "edge-match-identity-rekey"`). A rollback that would change an identity-enabled graph's identity profile, ontology or node kinds is refused with `ConfigurationError` `IDENTITY_ROLLBACK_REQUIRES_MIGRATION`: rebuilding the identity closure needs the graph definition, so commit that version's definition forward with `migrateSchema()` instead. Every commit path composes these checks in one fixed order: structural gates, edge match identity, ontology tightening, then the identity closure rebuild. + ### Breaking - `ConstraintFenceViolation` gains an `edgeEndpointAssignability` member, carrying `edgeKind`, `allowedPairs` and `edges` instead of a claim `target`.

The bump is one-way and deployment-visible: a database stamped 3 is caught up in place by the next privileged open (`createStoreWithSchema` / `createAdapterStoreWithSchema`) or an explicit `backend.adoptBaseSchema()`, and until one of those runs, a DML-only or zero-DDL runtime (`createVerifiedStore`, graph-template attach) refuses with `BaseSchemaMigrationError`, so privileged adoption must finish before those workers start. Once a database is stamped 4, a TypeGraph release that knows only version 3 (0.68 and earlier) refuses it as newer; there is no downgrade path. A custom SQL engine profile's `BaseSchemaRuntime` gains two required members, `identityTransitionsTableDdl` (the transition log's `CREATE TABLE` followed by its `CREATE INDEX` statements) and `identityTransitionRetentionTableDdl` (the retention watermark's `CREATE TABLE`), which back the version-4 adoption step; a profile whose adoption-step registry stops at 3 fails to construct (`CompilerInvariantError`, "adoption registry must end at the current version"). A deployment whose migration tooling enumerates TypeGraph's relations, or whose database role has restricted DDL, must account for both relations before upgrading. - Restoring an archival export (`identityMode: "archival"`) whose source graph retains identity transitions or has ever pruned them now requires the restore target to be opened with `history: true`. `importGraph` and `importGraphStream` refuse such a document with `IDENTITY_REPLAY_REQUIRES_HISTORY` before writing anything, where they previously wrote the rest of it successfully. diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md index 490fd11ea..ed5d70c68 100644 --- a/.changeset/ontology-change-classification.md +++ b/.changeset/ontology-change-classification.md @@ -4,7 +4,7 @@ **`isStructuralSubtype(child, parent)`** joins the `@nicia-ai/typegraph/schema` entrypoint: a structural-subtyping check over TypeGraph's projected JSON Schema fragment that answers whether every value satisfying `child` is guaranteed to satisfy `parent`. The verdict is three-way — `subtype`, `not-subtype` with the deepest failing reason and path, or `incomparable` when either side carries a construct the projection cannot judge (`$ref`, `allOf`, `not`, unmodeled JSON Schema keywords, or nesting past the depth guard) — so an unjudgeable pair is refused rather than accepted.

It answers a different question from the migration classifier's `isBreakingPropertyChange`, which asks whether existing rows stay valid after a schema edit; the two disagree in both directions and the module documents why.

The whole is a node or a { kind, id } reference, and only its kind and id are read, so a whole node whose own schema has properties named like attachment options cannot leak into the attachment. Unknown top-level keys, including the flat { kind, id } form, are refused with ValidationError on every surface. On a typed collection, whole.kind is limited to the whole kinds the ontology declares for that part kind through partOf/hasPart (CompositionWholeKinds). The restriction falls back to any node kind of the graph when the ontology declares a subclass or equivalence relation or has lost its tuple type, and StoreProjection erases it. reparent takes at as its only move instant: NodeReparentOptions no longer has validFrom, and COMPOSITION_REPARENT_INSTANT_CONFLICT is removed with its last trigger. validTo stays as the new attachment's upper bound. --- .changeset/composition.md | 8 +- apps/docs/src/content/docs/errors.md | 6 +- apps/docs/src/content/docs/limitations.md | 19 +- apps/docs/src/content/docs/ontology.md | 55 ++- apps/docs/src/content/docs/schemas-stores.md | 6 +- .../examples/28-composition-lifecycle.ts | 25 +- packages/typegraph/src/errors/index.ts | 8 +- packages/typegraph/src/index.ts | 1 + packages/typegraph/src/query/builder.ts | 1 + packages/typegraph/src/query/builder/index.ts | 1 + packages/typegraph/src/query/builder/types.ts | 93 +++++ packages/typegraph/src/query/index.ts | 1 + .../store/operations/composition-create.ts | 240 ++++++++--- .../src/store/operations/node-operations.ts | 59 +-- packages/typegraph/src/store/types.ts | 111 +++-- .../test-d/composition-via.test-d.ts | 15 +- .../test-d/composition-whole.test-d.ts | 290 +++++++++++++ .../atomic-node-batch-eligibility.test.ts | 2 +- .../atomic-resolved-update-batch.test.ts | 2 +- .../integration/composition-attachment.ts | 380 ++++++++++++++---- .../integration/composition-existence.ts | 80 ++-- .../integration/composition-tightening.ts | 2 +- .../concurrent-constraint-fence.test.ts | 4 +- .../tests/bulk-create-batching.test.ts | 23 +- .../composition-attachment-fence.test.ts | 56 ++- .../composition-reparent-instant.test.ts | 54 ++- .../tests/composition-subgraph-depth.test.ts | 8 +- .../composition-orphan-unattached.test.ts | 6 +- .../tests/graph-merge/durable-branch.test.ts | 2 +- ...de-upsert-batch-composition-pglite.test.ts | 2 +- .../composition-existence-import.test.ts | 2 +- .../tests/provenance-composition.test.ts | 19 +- 32 files changed, 1207 insertions(+), 374 deletions(-) create mode 100644 packages/typegraph/test-d/composition-whole.test-d.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 22523466e..cb2fdb8b9 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -6,11 +6,11 @@ **`partOf` / `hasPart` gain `existence?: "optional" | "required"`** (default `"optional"`, so existing declarations keep their semantics): `"required"` says a part of that kind can never exist without a live whole, and `KindRegistry.compositionExistence(kind)` reports it.

Any other top-level key on the attachment refuses with `ValidationError` (issue path `partOf.`) rather than being dropped.

The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`.

Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move.

How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` keeps its create-time meaning, the upper bound of the new attachment.

Identity truth is carried by fixed, reported rules: duplicate assertions reduce to one survivor with the rest reported as dropped, a doubly-ended assertion ends at the earliest staged `validTo`, a convergent retract and re-assert lands both, and opposing relations or a retract/reassert race fail the plan. The class-lifted `different` separation veto stays always-on. Removed with the bag: identity-driven candidate pairing and its `identity` match source, the assertion-conflict policies and callback, the provenance-conflict refusal and its error code, the edge and uniqueness "flag" plan-rebuild loop with its counterfactual uniqueness probe, the edge-fold collapse report, the `assertion`, `edge` and `uniqueness` arms of `IdentityUnresolvedConflict`, `IdentityReconciliation` and the report and plan-artifact field that carried it, and the `policy` member of a transition's decision provenance. An option `MergeOptions` does not declare is now refused by normalization instead of dropped, so a stated `identity` bag fails every merge, plan and review entry point. The archival interchange decision schema is strict, so a document carrying decision evidence the format does not define is rejected rather than stripped. Merge-caused transitions still record cause `reconcile` with the branch, branch ancestry, plan digest, review digest and source id. --- .changeset/identity-reconciliation.md | 18 +- apps/docs/src/content/docs/errors.md | 18 +- apps/docs/src/content/docs/graph-merge.md | 198 +-- apps/docs/src/content/docs/identity.md | 14 +- .../typegraph/etc/api-surface-exceptions.json | 56 - packages/typegraph/scripts/api-report.ts | 9 +- .../src/graph-merge/durable-merge.ts | 5 +- .../typegraph/src/graph-merge/edge-repoint.ts | 136 +- packages/typegraph/src/graph-merge/errors.ts | 11 +- .../typegraph/src/graph-merge/evidence.ts | 22 - .../src/graph-merge/identity-decision.ts | 83 +- .../src/graph-merge/identity-pairing-paths.ts | 253 --- ...tity-pairing.ts => identity-separation.ts} | 11 +- .../src/graph-merge/identity-three-way.ts | 810 ++------- packages/typegraph/src/graph-merge/index.ts | 11 - .../src/graph-merge/merge-identity.ts | 43 +- packages/typegraph/src/graph-merge/merge.ts | 1541 ++--------------- packages/typegraph/src/graph-merge/options.ts | 148 +- .../typegraph/src/graph-merge/plan-schema.ts | 116 +- packages/typegraph/src/graph-merge/sources.ts | 152 -- .../src/graph-merge/typegraph-internal.ts | 11 +- packages/typegraph/src/graph-merge/types.ts | 227 +-- packages/typegraph/src/identity/index.ts | 2 - packages/typegraph/src/identity/separation.ts | 7 +- .../typegraph/src/identity/transition-log.ts | 21 - packages/typegraph/src/index.ts | 2 - packages/typegraph/src/interchange/types.ts | 21 +- .../src/store/claims/resolved-node-claims.ts | 56 +- packages/typegraph/src/store/runtime-port.ts | 20 - packages/typegraph/src/store/store.ts | 17 - .../tests/graph-merge/commit.test.ts | 1 - .../composition-orphan-unattached.test.ts | 1 - .../tests/graph-merge/edge-repoint.test.ts | 41 - .../identity-commit-closure.test.ts | 2 - .../identity-decision-apply-parity.test.ts | 135 -- .../identity-decision-provenance.test.ts | 137 ++ .../graph-merge/identity-flag-rebuild.test.ts | 1264 -------------- .../graph-merge/identity-options.test.ts | 339 ---- .../identity-pairing-paths.test.ts | 145 -- .../graph-merge/identity-pairing.test.ts | 898 ---------- .../identity-reconciliation.test.ts | 183 +- ...entity-separation-storage-missing.test.ts} | 65 +- .../identity-separation-veto.test.ts | 588 +++++++ .../graph-merge/identity-three-way.test.ts | 609 ++----- .../node-delete-policy-wiring.test.ts | 1 - .../graph-merge/undeclared-options.test.ts | 250 +++ .../graph-merge/uniqueness-handoff.test.ts | 2 +- .../tests/identity-import-hardening.test.ts | 123 ++ .../tests/identity-transition-log.test.ts | 4 +- 49 files changed, 1818 insertions(+), 7009 deletions(-) delete mode 100644 packages/typegraph/src/graph-merge/identity-pairing-paths.ts rename packages/typegraph/src/graph-merge/{identity-pairing.ts => identity-separation.ts} (96%) delete mode 100644 packages/typegraph/tests/graph-merge/identity-decision-apply-parity.test.ts create mode 100644 packages/typegraph/tests/graph-merge/identity-decision-provenance.test.ts delete mode 100644 packages/typegraph/tests/graph-merge/identity-flag-rebuild.test.ts delete mode 100644 packages/typegraph/tests/graph-merge/identity-options.test.ts delete mode 100644 packages/typegraph/tests/graph-merge/identity-pairing-paths.test.ts delete mode 100644 packages/typegraph/tests/graph-merge/identity-pairing.test.ts rename packages/typegraph/tests/graph-merge/{identity-pairing-storage-missing.test.ts => identity-separation-storage-missing.test.ts} (60%) create mode 100644 packages/typegraph/tests/graph-merge/identity-separation-veto.test.ts create mode 100644 packages/typegraph/tests/graph-merge/undeclared-options.test.ts diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index b5fbcba45..6cc0878b0 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -2,29 +2,35 @@ "@nicia-ai/typegraph": minor --- -**Identity-aware reconciliation.** An identity-enabled graph with history capture now retains a replayable identity history: `store.identity.transitionsOf(ref)` returns every transition that changed a node's identity class — assertions, retractions, same-id folds, deletes and restores, validity-window ends, kind drops, schema transitions and reconciliation decisions — each carrying the assertion ids involved, both temporal coordinates, and, for a decision made by a merge, the policy arm, branch, branch ancestry and plan and review digests that produced it.

Bounding the answer with `fromRecorded`/`toRecorded` never bounds the lineage search, so a window can never hide the note that names an earlier class canonical. `store.identity.replay(ref)` pairs each transition with the class membership before and after it, reconstructed through the same historical reader `asOf` and `asOfRecorded` reads use, so replay can never disagree with a live read. Replay requires `history: true` and refuses with `IDENTITY_REPLAY_REQUIRES_HISTORY` otherwise, or with `IDENTITY_REPLAY_ENGINE_NATIVE_UNSUPPORTED` on a backend that owns recorded time itself, where TypeGraph captures no history to replay; Cloudflare D1 and neon-http continue to refuse identity-enabled graphs outright. `pruneIdentityTransitions(store, { beforeRecorded })` trims retained explanations and records a watermark that replay reports rather than hiding. Archival interchange carries a `transitions` section plus the retention watermark, bumping the interchange format to `3.0`; older documents still import and validate unchanged. Restoring an archive's transitions validates shape only and never re-derives membership, every restored row is marked as such so `replay` never pairs it with a fabricated before/after, and when the destination has no identity transitions of its own yet the restore also sets its own watermark, so `replay` reports the pre-restore range honestly instead of claiming a complete history it cannot reconstruct. -**Graph merge gains identity reconciliation under a new `identity` merge-options bag.** `pairing` lets an explicit `same` assertion propose or force a candidate match between nodes created under different ids, and a class-lifted `different` assertion now vetoes a match at plan time instead of aborting at commit. `onAssertionConflict` makes retract/reassert races and independently duplicated assertions resolvable by policy instead of only refusable, and `onProvenanceConflict` states how contradictory branch attribution across a fused cluster is handled. `onEdgeConflict: "flag"` drops an identity pairing whose repoint collapsed two distinct relationships onto one edge, and `onUniquenessConflict: "flag"` drops a pairing whose fused entity would violate a unique constraint, at plan time rather than failing at commit. Both `"flag"` dispositions rebuild the plan without the dropped pairings — repeating until no pairing-induced conflict remains, which terminates because every pass drops a pairing no earlier pass did — and leave it applicable; a collision a member would cause on its own is never blamed on a pairing and stays with the commit's refusal; the assertion still lands in the identity ledger, only its use as a candidate pairing is dropped. Every unresolved case is reported as a typed `IdentityUnresolvedConflict` on the merge report and inside the durable plan, and the policy bag is part of the review digest, so a plan cannot be applied under policies its reviewer did not approve. Defaults preserve current behavior exactly: `pairing: "off"`, `onAssertionConflict: "refuse"`, `onProvenanceConflict: "keepBoth"`, `onEdgeConflict: "repoint"`, `onUniquenessConflict: "refuse"`. +**Graph merge carries identity truth with fixed, reported rules.** There is no identity policy to configure. A merge three-way classifies every staged identity assertion and retraction against the target's current truth, and each one ends as a write, a `dropped` entry with a reason, or a refusal that names it: duplicate assertions of one pair reduce to one survivor (an id the target already holds, then the earliest `validFrom`, then the code-point-smallest id) with the rest reported as `identity:duplicate-assertion`; a branch that retracts a pair and re-asserts it itself lands both; branches asserting opposing relations for one pair, or one branch retracting a pair another re-asserts, fail the merge with `GRAPH_MERGE_IDENTITY_CONFLICT`. A `same` assertion is ledger truth the merge carries across — it never fuses the rows it names. -One narrow, deliberate behavior change ships under the default policy: when two branches end the same base identity assertion at different valid-time instants, the merge commits the earliest staged `validTo` rather than whichever branch happened to be staged last.

A scored match between separated entities is dropped, the merge continues, and the pair is reported as an `IdentityUnresolvedConflict` (`kind: "separation"`, naming both entities, the separating assertion and the source that proposed the match) on the new `MergeReport.identityConflicts` and on a plan artifact's optional `review.identityConflicts`; candidate diagnostics report the pair as `excluded` with reason `"separation"`. A definitional match that survives the base and diameter guards, or a cluster that fuses a separated pair through a third node, fails the plan with the new code `GRAPH_MERGE_IDENTITY_SEPARATION_CONFLICT` on `IdentityMergeConflictError`. `MERGE_PLAN_FORMAT_VERSION` and `MERGE_REVIEW_FORMAT_VERSION` stay at 2: `review.identityConflicts` is omitted when empty, so a plan the veto never touched is byte-identical to one written before it existed. + +Every transition a merge causes is recorded with cause `reconcile` and a `decision` naming the branch (when exactly one was merged), the root-first branch ancestry, the plan digest when a plan artifact was applied, and the review digest and source id the applier supplied. + +One narrow, deliberate behavior change ships in how a merge ends an assertion: when two branches end the same base identity assertion at different valid-time instants, the merge commits the earliest staged `validTo` rather than whichever branch happened to be staged last. The rule is deterministic and branch-order-independent, but it is a real change to which instant a merge commits. A durable merge plan built under `reconcileTypes: "ontology"` also no longer fails its own artifact validation ("A resolution must name its complete guarded cluster and carry exactly N-1 decisive edges") when a retype cluster spans several ids: the resolution now names the kind the canonical row is written under, the reconciled kind `TypeReconciliation.toType` records, rather than the staged survivor's pre-retype kind. A transaction receipt's `writes.identity` gains `transitions`, counted beside and never inside `total`: the number of identity transition-log notes the transaction's flush wrote. -`applyMergePlanInTransaction()` records the same identity decision as `applyMergePlan()` for one plan: the policy arms the plan's review recorded, including an `edge` or `uniqueness` flag, now reach the transition log from a caller-owned transaction too. `applyDurableMergePlan()` offers a plan to a strategy's native `merge()` only when the plan carries no identity or composition work — identity assertion or retraction writes, identity reconciliations or conflicts, a reported composition orphan, or a write to a composition whole, part or edge kind — and applies every other plan through the portable path, which owns the transition log, closure maintenance, and composition enforcement. +`applyMergePlanInTransaction()` records the same identity decision as `applyMergePlan()` for one plan. `applyDurableMergePlan()` offers a plan to a strategy's native `merge()` only when the plan carries no identity or composition work — identity assertion or retraction writes, an identity separation conflict, a reported composition orphan, or a write to a composition whole, part or edge kind — and applies every other plan through the portable path, which owns the transition log, closure maintenance, and composition enforcement. ### Breaking -- `IdentityUnresolvedConflict` gains two arms, `kind: "edge"` and `kind: "uniqueness"`, reported when `identity.onEdgeConflict: "flag"` or `identity.onUniquenessConflict: "flag"` drops a pairing. The `"edge"` arm names `edgeKind`, the two refs `a` and `b`, the `canonical` ref, the collapsed `side` and `edgeIds`; the `"uniqueness"` arm names `constraintName`, `fields`, `canonical`, the `owner` that holds the key, the `loser` write the store refused for it, and the cluster's `members`. Both carry the dropped pairing's `assertionIds` and `branches`. An exhaustive `switch` over `conflict.kind` must handle both; the durable plan artifact's strict `review.identityConflicts` schema admits both. +- A merge option `MergeOptions` does not declare is refused with `InvalidMergeOptionsError` (`details.option` names the key) by every merge and plan entry point (`merge()`, `mergeIncremental()`, `planMerge()`, `planMergeIncremental()`, …) and by candidate write-set review, where it was previously ignored. Remove the key, or correct its spelling. +- A candidate match between two entities whose identity classes a `different` assertion holds apart no longer reaches the commit. A scored match is dropped and reported on `MergeReport.identityConflicts`, and the merge succeeds where it previously failed in the commit; a definitional match or a transitive cluster fails at plan time with `GRAPH_MERGE_IDENTITY_SEPARATION_CONFLICT` rather than the commit's generic refusal. `IdentityMergeConflictError.code` is typed `IdentityMergeConflictCode`, the union of that code and `GRAPH_MERGE_IDENTITY_CONFLICT`. +- `MergeReport` gains the required member `identityConflicts`, and `CandidateDiagnostic`'s `clusterDisposition.reason` gains `"separation"`. Code that constructs a `MergeReport`, or switches exhaustively over the exclusion reason, must account for both. - `EntityResolution.kind` (on `MergeReport.resolutions` and a plan artifact's `review.resolutions`) names the reconciled kind for a cluster the ontology cascade retypes. Code that joined a resolution to its staged members by the survivor's pre-retype kind should read `TypeReconciliation.fromTypes` for the staged kinds; clusters no retype touches are unchanged. - `store.identity.transitionsOf` returns `{ transitions, nextFrom? }` rather than a bare array. Destructure the result (`const { transitions } = await store.identity.transitionsOf(ref)`). `nextFrom` is a `TransitionPageCursor`, not a `RecordedInstant`: pass it back as `fromRecorded`, never to `store.asOfRecorded`. -- `IdentityDecisionProvenance.policy` is an `IdentityDecisionPolicyRecord` (`assertion`, `edge`, `uniqueness`, and the other exercised axes), not a comma-joined string. A switch on `policy.assertion` is exhaustive over the assertion arms; `"flag"` on `edge` or `uniqueness` is present when that axis dropped a pairing. - `IDENTITY_REPLAY_LIMIT_EXCEEDED` is gone from `IdentityReplayErrorDetails` and the error catalog. A lineage with more boundaries than `limit` now pages: `replay` and `transitionsOf` return a `nextFrom` recorded instant naming the first boundary the page stopped short of. Code that caught the refusal and resumed from `details.resumeFromRecorded` reads `nextFrom` off the successful result instead. - Lineage discovery no longer honors `fromRecorded`/`toRecorded`, so a narrow-window audit read now scans the full lineage on every call. Only a class lineage whose transition rows exceed an internal safety ceiling hits `IDENTITY_REPLAY_WALK_INCOMPLETE`, whose only remedy remains the destructive `pruneIdentityTransitions`. - The identity transition log adds two deployment-wide relations, `typegraph_identity_transitions` and `typegraph_identity_transition_retention`, created for every database whether or not any graph in it enables identity, with `createSqlSchema` accepting `identityTransitions` and `identityTransitionRetention` as optional name overrides and `ResolvedSqlTableNames` gaining both as required members. They ship as a new base-schema release: `CURRENT_BASE_SCHEMA_VERSION` advances from 3 to 4, id `"identity-transition-log"`, adopting both relations through `CREATE TABLE IF NOT EXISTS` and their indexes (idempotent, safe to run concurrently, and a no-op on a fresh install whose generated DDL already carries them). The bump is one-way and deployment-visible: a database stamped 3 is caught up in place by the next privileged open (`createStoreWithSchema` / `createAdapterStoreWithSchema`) or an explicit `backend.adoptBaseSchema()`, and until one of those runs, a DML-only or zero-DDL runtime (`createVerifiedStore`, graph-template attach) refuses with `BaseSchemaMigrationError`, so privileged adoption must finish before those workers start. Once a database is stamped 4, a TypeGraph release that knows only version 3 (0.68 and earlier) refuses it as newer; there is no downgrade path. A custom SQL engine profile's `BaseSchemaRuntime` gains two required members, `identityTransitionsTableDdl` (the transition log's `CREATE TABLE` followed by its `CREATE INDEX` statements) and `identityTransitionRetentionTableDdl` (the retention watermark's `CREATE TABLE`), which back the version-4 adoption step; a profile whose adoption-step registry stops at 3 fails to construct (`CompilerInvariantError`, "adoption registry must end at the current version"). A deployment whose migration tooling enumerates TypeGraph's relations, or whose database role has restricted DDL, must account for both relations before upgrading. - Restoring an archival export (`identityMode: "archival"`) whose source graph retains identity transitions or has ever pruned them now requires the restore target to be opened with `history: true`. `importGraph` and `importGraphStream` refuse such a document with `IDENTITY_REPLAY_REQUIRES_HISTORY` before writing anything, where they previously wrote the rest of it successfully. +- An archival interchange document's transition `decision` is validated strictly: `branchId`, `branchAncestry`, `mergePlanDigest`, `reviewDigest` and `sourceId` are the only members, and a document carrying any other is refused with a `ValidationError` before anything is written rather than restored with that member dropped. diff --git a/apps/docs/src/content/docs/errors.md b/apps/docs/src/content/docs/errors.md index dd218bcf9..1be49731c 100644 --- a/apps/docs/src/content/docs/errors.md +++ b/apps/docs/src/content/docs/errors.md @@ -378,14 +378,11 @@ convergent, not a conflict, and merges cleanly), or a branch asserts an identity relation over a node another branch deleted.

A scored match between separated entities is dropped, the merge continues, and the pair is reported as an `IdentityUnresolvedConflict` (`kind: "separation"`, naming both entities, the separating assertion and the source that proposed the match) on the new `MergeReport.identityConflicts` and on a plan artifact's optional `review.identityConflicts`; candidate diagnostics report the pair as `excluded` with reason `"separation"`. A definitional match that survives the base and diameter guards, or a cluster that fuses a separated pair through a third node, fails the plan with the new code `GRAPH_MERGE_IDENTITY_SEPARATION_CONFLICT` on `IdentityMergeConflictError`. `MERGE_PLAN_FORMAT_VERSION` and `MERGE_REVIEW_FORMAT_VERSION` stay at 2: `review.identityConflicts` is omitted when empty, so a plan the veto never touched is byte-identical to one written before it existed. +A class-lifted `different` assertion now vetoes a candidate match at plan time on every identity-enabled merge, instead of aborting inside the commit on a database constraint.

The window is now validated once where the attachment is read, and the satisfied verdict compares each stated bound against the stored one, refusing a difference. A validTo on a oneActive pair wrote an edge the incumbent read does not count, so a repeated get-or-create inserted it again and a different whole was accepted beside it.

The window is validated once for every surface (canonical bounds, ordered pair), and on a `population: "oneActive"` pair, where only an open-ended edge is a membership, a stated `validTo` refuses with `ValidationError` (code `COMPOSITION_ATTACHMENT_WINDOW_BOUNDED`) instead of writing an edge that attaches nothing. The write is atomic: a dead or missing whole, an undeclared pair, or a lost composition claim aborts the node create too, leaving no orphan row. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written; `partOf` is honored on an optional-existence pair too. A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. -**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. +**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment.

A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. **`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` is refused the same way: a move opens the new attachment, and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction. diff --git a/apps/docs/src/content/docs/ontology.md b/apps/docs/src/content/docs/ontology.md index fc309dda1..3db1e59bb 100644 --- a/apps/docs/src/content/docs/ontology.md +++ b/apps/docs/src/content/docs/ontology.md @@ -462,7 +462,14 @@ refusal, or an acyclicity refusal aborts the node create too. `subgraph({ composition: { via } })` take the same value and refuse a via that realizes no pair, rather than silently walking every realizing edge. - **`validFrom` / `validTo`** are the realizing edge's window, not the part - node's.

A caller that caught the EdgeAcyclicityError inside store.transaction and committed kept the cycle. bulkCreate, bulkInsert, bulkUpsertById and bulkGetOrCreateByEndpoints all reach the two batch executors, which now probe the prepared rows as an overlay on the stored relation before their first write. The overlay probe walks only stored edges (an index seek per hop, like the single-row probe) and returns which proposed rows each proposed row reaches; the cycle among those reaches is decided in memory, so an in-batch cycle is seen without the whole-relation materialization the plan-time form pays. --- .changeset/edge-kind-integrity.md | 2 +- packages/typegraph/src/store/acyclicity.ts | 237 +++++++++++++----- .../src/store/operations/edge-operations.ts | 95 ++++--- packages/typegraph/src/store/recursive-cte.ts | 38 ++- ...sed-write-in-enclosing-transaction.test.ts | 58 ----- ...atch-cycle-survives-caught-refusal.test.ts | 93 ------- .../backends/integration/edge-acyclicity.ts | 74 ++++++ .../sqlite/edge-acyclicity-query-plan.test.ts | 4 +- .../tests/bulk-create-batching.test.ts | 5 +- .../typegraph/tests/edge-acyclicity.test.ts | 122 +++++++-- 10 files changed, 437 insertions(+), 291 deletions(-) delete mode 100644 packages/typegraph/tests/audit-probes/fallback-parity/acyclic-batch-cycle-survives-caught-refusal.test.ts diff --git a/.changeset/edge-kind-integrity.md b/.changeset/edge-kind-integrity.md index 5a248727d..552426721 100644 --- a/.changeset/edge-kind-integrity.md +++ b/.changeset/edge-kind-integrity.md @@ -6,7 +6,7 @@ The target allowance is scoped to the graph, the edge kind, the target kind and the target id, and deliberately not to the source: two permitted source kinds contend for one allowance, while equal ids under different target kinds, edge kinds or graphs never collide. `"one"` counts every non-deleted edge at the target, including edges with a validity end; `"oneActive"` counts only those whose `validTo` is unset.

Every write path that can put an edge into that relation — `create`, `bulkCreate`, upsert and `getOrCreateByEndpoints`, resurrection into the live population, validating import, and merge apply — is refused with the new `EdgeAcyclicityError` when the new edge's `to` endpoint already reaches its `from` endpoint; a self-loop is a cycle of length one and is refused by the same rule. A batch (`bulkCreate`, `bulkInsert`, `bulkUpsertById`, `bulkGetOrCreateByEndpoints`) is checked as a whole before its first row is written, including a cycle two of its own rows close through each other, so a refusal caught inside an enclosing `store.transaction(...)` leaves none of the batch stored. The check is exhaustive, with no depth bound, so a cycle of any length is found. Non-deleted edges count regardless of their validity window, so ending an edge's window does not free the relation while soft-deleting it does.

A violation is the new typed `AcyclicityMergeConflictError` (code `GRAPH_MERGE_ACYCLICITY_CONFLICT`), carrying the offending relation name and every edge on the cycle (`edgeId`/`edgeKind`/`fromKind`/`fromId`/`toKind`/`toId`) in `details`, so a `planMerge()` review surfaces it before anything is written. A cycle that only appears from a write racing the plan is still caught at apply time as `MergeConstraintConflictError` wrapping `EdgeAcyclicityError`. diff --git a/packages/typegraph/src/store/acyclicity.ts b/packages/typegraph/src/store/acyclicity.ts index 5cbd733bd..3fefb213e 100644 --- a/packages/typegraph/src/store/acyclicity.ts +++ b/packages/typegraph/src/store/acyclicity.ts @@ -5,7 +5,9 @@ * THE acyclicity predicate: "does `from` lie in the reflexive-transitive * closure of `to`, over one acyclic relation's live edges".

Two paths committed the same loss unprobed: removing a kind from the middle of a subclass chain (the removed-kind rule classified both dropped relations safe and discarded the delta), and narrowing an edge kind's own from/to declaration (no relation changed, so no delta was computed at all). edgeEndpointAdmissionLosses is now the one owner of that decision. It runs whenever a relation changed or a declared endpoint pair was dropped, ignores lost pairs naming a kind the commit removes, and keeps those pairs in the probe allowance so rows the removal reclaims never block it. A loss no relation change carries is reported as its own edgeRegistration change, so ensureSchema, migrateSchema, Store.evolve, Store.removeKinds, planEvolution and rollbackSchema all probe it through the existing tightening preflight. --- .changeset/ontology-change-classification.md | 3 +- .../docs/src/content/docs/graph-extensions.md | 8 + .../docs/src/content/docs/schema-evolution.md | 17 +- .../typegraph/src/schema/ontology-change.ts | 222 +++++++++++---- packages/typegraph/src/store/store.ts | 10 +- .../edge-endpoint-narrowing-commit.test.ts | 43 --- .../removal-surviving-subclass-edge.test.ts | 53 ---- .../integration/ontology-tightening.ts | 257 +++++++++++++++++- .../typegraph/tests/ontology-change.test.ts | 206 +++++++++++++- 9 files changed, 650 insertions(+), 169 deletions(-) delete mode 100644 packages/typegraph/tests/audit-probes/schema-transition-state/edge-endpoint-narrowing-commit.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/schema-transition-state/removal-surviving-subclass-edge.test.ts diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md index ed5d70c68..3478a6b3f 100644 --- a/.changeset/ontology-change-classification.md +++ b/.changeset/ontology-change-classification.md @@ -4,7 +4,7 @@ **`isStructuralSubtype(child, parent)`** joins the `@nicia-ai/typegraph/schema` entrypoint: a structural-subtyping check over TypeGraph's projected JSON Schema fragment that answers whether every value satisfying `child` is guaranteed to satisfy `parent`.

Adding or removing `inverseOf` or `implies` is now `breaking`: both change what a default `expand` traversal returns, so they need an explicit `migrateSchema()`, exactly like the Operational Identity `sameIdAcrossKinds` flip. Adding `partOf`/`hasPart` is `warning`, probed for a part with more than one live whole and for a composition cycle (plus a part with no live whole when the pair is `existence: "required"`); removing one is `breaking`, like `inverseOf`/`implies`. Removing `disjointWith` stays `safe`, and `broader`/`narrower`/`relatedTo`/`differentFrom` stay `safe` in both directions. A relation whose `from` or `to` names a kind the same commit removes is itself `safe`, and rows of the removed kind never block the commit. An edge kind that stops admitting an endpoint pair between surviving kinds is probed the same way whatever caused the loss — a removed `subClassOf`/`equivalentTo`, a narrowed `from`/`to` declaration (reported as an `entity: "edgeRegistration"` change), or a kind removed from the middle of a subclass chain — so `Store.removeKinds()` refuses when a surviving subclass's live edge was admitted only through the removed kind. `ChangeSeverity` itself is unchanged — `warning` now means "auto-migrates only if the data allows it". **A refused tightening throws `MigrationError`** with `details.reason: "ontology-tightening-violated"` and `details.violations` in exactly the shape `store.verifyConstraintFences()` returns, so the same rows that block the migration can be listed, resolved, and the migration retried. The audit gains an `edgeEndpointAssignability` family reporting live edges sitting outside every declared endpoint pair. A backend implementing `readConstraintFenceViolations` may receive an `edgeEndpointAllowances` declaration and must answer with `misassignedEdgeEndpointRows`; omitting the key when the family was requested is refused with `CONSTRAINT_FENCE_AUDIT_FAMILY_UNSUPPORTED` rather than reported as a clean result. A backend that cannot commit a preflight atomically refuses a tightening with `ONTOLOGY_TIGHTENING_REQUIRES_ATOMIC_BACKEND`, and a preflight target that cannot run the audit refuses with the existing `CONSTRAINT_FENCE_AUDIT_UNSUPPORTED`. One residual window remains: a writer that commits under the previous schema version between the probe and the version compare-and-set is not seen, so `store.verifyConstraintFences()` remains the post-hoc detector. @@ -18,6 +18,7 @@ - A custom backend implementing `readConstraintFenceViolations` must answer `misassignedEdgeEndpointRows`, which the audit now requests for every registered edge kind.

A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. **`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`.

A transition caused by an identity assertion or retraction the merge applied is recorded with cause `reconcile`; one caused by a node row the merge wrote keeps the cause that names its mechanism — `detach` for a deleted class member, `fold` for a created same-ID peer — and carries the same `decision`. `merge()`, `mergeIncremental()`, `applyMergePlan()`, `applyMergePlanInTransaction()` and `applyDurableMergePlan()` order their node and identity writes the same way, so a plan that retracts an assertion and ends one endpoint's validity window lands through every one of them. One narrow, deliberate behavior change ships in how a merge ends an assertion: when two branches end the same base identity assertion at different valid-time instants, the merge commits the earliest staged `validTo` rather than whichever branch happened to be staged last. The rule is deterministic and branch-order-independent, but it is a real change to which instant a merge commits. diff --git a/apps/docs/src/content/docs/identity.md b/apps/docs/src/content/docs/identity.md index c68243d6e..f3fc483cf 100644 --- a/apps/docs/src/content/docs/identity.md +++ b/apps/docs/src/content/docs/identity.md @@ -364,6 +364,13 @@ watermark](#archival-transitions-and-the-retention-watermark)). | `schema-transition` | A schema evolution reinterpreted membership under new `sameIdAcrossKinds` or ontology rules | | `reconcile` | A graph merge applied the assertion or retraction; the transition's `decision` names the branch, the branch ancestry, and the plan and review digests when a reviewed plan was applied (see [Graph merge](/graph-merge/#identity-conflicts)) | +`cause` names the mechanism that moved the membership; `decision` names what +governed it.

A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. **`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. diff --git a/apps/docs/src/content/docs/ontology.md b/apps/docs/src/content/docs/ontology.md index c38a406b6..fca03ca0b 100644 --- a/apps/docs/src/content/docs/ontology.md +++ b/apps/docs/src/content/docs/ontology.md @@ -434,7 +434,10 @@ const chapter = await store.nodes.Chapter.create( The node and its realizing composition edge are written in **one** transaction: a lost composition claim, a dead or missing whole, a cardinality -refusal, or an acyclicity refusal aborts the node create too. +refusal, or an acyclicity refusal aborts the node create too.

The schema diff compared the two literally, so every nullable, primitive-union and tuple property read as an incompatible property change and the graph could not be opened without migrateSchema(). propertySchemasEqual now folds both spellings in the one normalization every diff comparison already runs, rewriting only the keywords that spell them: a union member carrying any other keyword, a minItems below the prefix length, instance data and unknown extension keys compare exactly as before. classifyPropertyChanges uses the same comparison for its unchanged test, and the reading that an omitted items beside prefixItems closes a tuple has one owner shared with the structural-subtype predicate, which consequently reads the two tuple spellings as mutual subtypes.

The pre-write probe counted the edge kind being written, so a backend with no claim relation let a part attach to a second whole through a different realizing edge kind, and every path that probes before it claims (a custom command port answering unsupported, a batch, a kind declaring both axes, the atomic batch diagnostic) refused a second whole as CardinalityError with no incumbent, where the claim row raises CompositionError. checkEdgeCardinalityConstraints now takes the claim set the write owes and probes exactly those claims. The composition claim is counted across every holder the claim names, first, and refused through claimRefusalFor with the incumbent edge id, so the probe and the claim row cannot disagree about the error. Create, re-entry, import and the atomic diagnostic all pass the set they then claim. --- .changeset/composition.md | 2 + apps/docs/src/content/docs/backend-setup.md | 2 +- apps/docs/src/content/docs/errors.md | 8 +- packages/typegraph/src/interchange/import.ts | 20 +- .../typegraph/src/store/claims/edge-claims.ts | 53 +++- packages/typegraph/src/store/constraints.ts | 171 ++++++++---- .../store/operations/composition-create.ts | 2 +- .../src/store/operations/edge-operations.ts | 127 ++++----- ...on-claimless-cross-kind-two-wholes.test.ts | 69 ----- ...sal-class-differs-on-portable-path.test.ts | 65 ----- .../audit-probes/fallback-parity/harness.ts | 105 ------- .../backends/integration/composition-fence.ts | 72 +++++ .../backends/integration/edge-acyclicity.ts | 22 +- .../tests/composition-portable-probe.test.ts | 256 ++++++++++++++++++ .../typegraph/tests/edge-acyclicity.test.ts | 26 +- 15 files changed, 584 insertions(+), 416 deletions(-) delete mode 100644 packages/typegraph/tests/audit-probes/fallback-parity/composition-claimless-cross-kind-two-wholes.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/fallback-parity/composition-refusal-class-differs-on-portable-path.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/fallback-parity/harness.ts create mode 100644 packages/typegraph/tests/composition-portable-probe.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index b6ef8b507..e756c862f 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -10,6 +10,8 @@ **`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. +**A second whole is refused identically on every write path.** `CompositionError` with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`. A backend without claim relations therefore still holds "one whole per part" across two different realizing edge kinds, under the per-graph lock. + **`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` is refused the same way: a move opens the new attachment, and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction. **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts — `existence: "required"` governs bare creation and detachment, not whole deletion. `CompositionExistenceError.code` names the situation: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which optional detail fields are populated, so a handler may branch on either. diff --git a/apps/docs/src/content/docs/backend-setup.md b/apps/docs/src/content/docs/backend-setup.md index ee03e4cb7..b743c2d07 100644 --- a/apps/docs/src/content/docs/backend-setup.md +++ b/apps/docs/src/content/docs/backend-setup.md @@ -2422,7 +2422,7 @@ TypeGraph choosing separate query semantics per backend: | HNSW `efSearch` query tuning | ✗ | ✓ transactional HNSW drivers | Refused, never ignored: `UnsupportedBackendCapabilityError` with `details.capability` `vector.searchFrontierTuning` on **any** SQLite backend (vector and hybrid alike — neither `sqlite-vec`'s `vec0` KNN nor `libsql-native`'s DiskANN has a per-search frontier), and on transaction-less Postgres or a non-HNSW slot | | Bounded planner-statistics sampling | ✓ standard connections / ✗ D1 and Durable Objects | Native `ANALYZE` sampling | Restricted SQLite skips `analysis_limit` but still attempts scoped `ANALYZE`.

The delete-behavior decision is now a read-only owner the delete pipeline applies, and a frame that deletes more than one node asks it for every node, in deletion order, before its first statement, folding in the edges each earlier delete removes. bulkDelete plans and judges all of its items first for the same reason. --- .changeset/composition.md | 2 +- .../src/store/operations/node-operations.ts | 208 +++++++++++++----- .../store/operations/node-write-pipeline.ts | 71 ++++-- .../src/store/operations/write-session.ts | 2 +- ...fusal-half-applied-in-enclosing-tx.test.ts | 40 ---- .../delete-provenance-state/fixture.ts | 103 --------- .../integration/composition-existence.ts | 105 +++++++++ .../tests/composition-cascade.test.ts | 4 +- .../graph-merge/composition-orphan.test.ts | 2 +- 9 files changed, 315 insertions(+), 222 deletions(-) delete mode 100644 packages/typegraph/tests/audit-probes/delete-provenance-state/cascade-refusal-half-applied-in-enclosing-tx.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/delete-provenance-state/fixture.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 33d73fedc..7357567a7 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -14,7 +14,7 @@ **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed.

Every part's verdict, and the whole's, is reached before the first row is deleted, so a `RestrictedDeleteError` from a part deep in the closure leaves the whole closure intact, including when the caller catches it inside an enclosing `store.transaction(...)`; `bulkDelete` reaches every item's verdict before deleting any of them.

That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order, and the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them, and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent.

A watermark above the revision the graph's next commit takes sits over history that does not exist yet, so every later commit landed below it and replay reported freshly recorded history as truncated. The prune now reads the next revision inside its mutation and refuses a target beyond it with IDENTITY_PRUNE_BEYOND_RECORDED_CLOCK, deleting nothing.

Naming now has one owner that keeps a key's leading characters while no other key shares them (the names allocations already on disk carry) and tells the sharing keys apart by a hash of the whole key, asserting distinctness when the module loads. A fixed-schema working copy refused every schema-writing member except setActiveVersionWithPreflight, so a rollback that owed a preflight reactivated an older schema version on the copy. The member is now refused in the same pattern as its siblings, before its preflight runs. --- .../backend/capabilities/bundle-registry.ts | 4 +- .../drizzle/postgres-working-copy-names.ts | 85 ++++++++++++++ .../backend/drizzle/postgres-working-copy.ts | 28 ++--- .../clone-allocation-name-collision.test.ts | 44 -------- .../clone-fixed-schema-rollback.test.ts | 58 ---------- ...d-schema-set-active-with-preflight.test.ts | 67 ----------- ...ing-copy-allocation-name-collision.test.ts | 55 --------- ...res-working-copy-allocation-schema.test.ts | 10 +- .../postgres/postgres-working-copy.test.ts | 92 ++++++++++++++- .../tests/bundle-member-access.test.ts | 8 +- .../tests/capability-bundle-totality.test.ts | 6 +- .../postgres-working-copy-name-seams.test.ts | 106 ++++++++++++++++++ 12 files changed, 307 insertions(+), 256 deletions(-) create mode 100644 packages/typegraph/src/backend/drizzle/postgres-working-copy-names.ts delete mode 100644 packages/typegraph/tests/audit-probes/fork-clone-clear/clone-allocation-name-collision.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/fork-clone-clear/clone-fixed-schema-rollback.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/schema-transition-state/fixed-schema-set-active-with-preflight.test.ts delete mode 100644 packages/typegraph/tests/audit-probes/schema-transition-state/working-copy-allocation-name-collision.test.ts diff --git a/packages/typegraph/src/backend/capabilities/bundle-registry.ts b/packages/typegraph/src/backend/capabilities/bundle-registry.ts index b521af3b6..9f0689e67 100644 --- a/packages/typegraph/src/backend/capabilities/bundle-registry.ts +++ b/packages/typegraph/src/backend/capabilities/bundle-registry.ts @@ -968,8 +968,8 @@ export const UNBUNDLED_OPTIONAL_MEMBERS = { setActiveVersionWithPreflight: { kind: "reasoned", reason: - "Same schema-version write-fence family as commitSchemaVersionWithPreflight; rollbackSchema refuses with the tightening capability error when it is absent.", - accesses: 1, + "Same schema-version write-fence family as commitSchemaVersionWithPreflight; rollbackSchema refuses with the tightening capability error when it is absent, and a fixed-schema working copy refuses it when present.", + accesses: 2, }, lockSchemaVersionForWrite: { kind: "reasoned", diff --git a/packages/typegraph/src/backend/drizzle/postgres-working-copy-names.ts b/packages/typegraph/src/backend/drizzle/postgres-working-copy-names.ts new file mode 100644 index 000000000..8668fdc08 --- /dev/null +++ b/packages/typegraph/src/backend/drizzle/postgres-working-copy-names.ts @@ -0,0 +1,85 @@ +/** Physical relation names of one PostgreSQL working-copy allocation. */ +import { shortHash } from "../../query/dialect/vector-strategy"; +import { sha256Hex } from "../../utils/hash"; +import { requireDefined } from "../../utils/presence"; +import { + defaultPostgresTableNames, + type PostgresTableNames, +} from "./schema/postgres"; + +const PHYSICAL_PREFIX_LEAD = "tgw_"; +const ALLOCATION_DIGEST_BYTES = 12; +const RELATION_SUFFIX_LENGTH = 15; + +type RelationKey = keyof PostgresTableNames; + +function truncatedSuffix(key: string): string { + return key.slice(0, RELATION_SUFFIX_LENGTH); +} + +function hashedSuffix(key: string): string { + const hash = shortHash(key); + const readable = key.slice(0, RELATION_SUFFIX_LENGTH - hash.length - 1); + return `${readable}_${hash}`; +} + +/** + * One suffix per relation key, distinct across `keys`. + * + * A key keeps its leading characters while no other key shares them, which is + * what every allocation already on disk was named with.

A member that has left its class is a singleton in current state, and its departure is noted against the surviving class's canonical, so the walk from a deleted or split-away member matched nothing and returned an empty page for a node whose history was sitting in the log. The walk is now also seeded from the recorded evidence that ever tied the reference to a class: every same assertion version that named it and, on a folding graph, every node version that shared its id, followed to a fixed point. Both entry points share the one seed owner. Archivally restored transitions carry no such evidence on the destination, so a restored row the walk does not reach can be neither tied to the reference nor ruled out. The result reports their count as incompleteDiscovery.unattributedRestoredTransitions instead of returning a short page that looks complete. The exhaustiveness property now deletes the replay seed too. Revisions the seed sat out entirely are exempt from the touched-implies-changed direction, since a class the seed left keeps a history of its own; the departure boundary itself is checked in full. --- .changeset/identity-reconciliation.md | 2 + apps/docs/src/content/docs/identity.md | 29 +++ packages/typegraph/src/identity/index.ts | 1 + .../src/identity/lineage-evidence.ts | 139 ++++++++++++ packages/typegraph/src/identity/replay.ts | 163 ++++++++++++-- .../typegraph/src/identity/transition-log.ts | 18 ++ packages/typegraph/src/index.ts | 1 + .../identity-log-state.test.ts | 21 -- .../backends/integration/identity-replay.ts | 198 ++++++++++++++++++ .../identity-replay-exhaustive.test.ts | 65 ++++-- 10 files changed, 580 insertions(+), 57 deletions(-) create mode 100644 packages/typegraph/src/identity/lineage-evidence.ts diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 6097576eb..c3216409e 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -6,6 +6,8 @@ `transitionsOf` and `replay` both page: `limit` caps the number of boundaries one page returns, and a capped page hands back a `nextCursor` to pass as the next call's `cursor`. The cursor is a position within the windowed lineage, so it composes with `fromRecorded`/`toRecorded` by intersection, and `fromRecorded`/`toRecorded` refuse a page cursor with a `ValidationError`. Bounding the answer with `fromRecorded`/`toRecorded` never bounds the lineage search, so a window can never hide the note that names an earlier class canonical. `store.identity.replay(ref)` pairs each transition with the class membership before and after it, reconstructed through the same historical reader `asOf` and `asOfRecorded` reads use, so replay can never disagree with a live read. Replay requires `history: true` and refuses with `IDENTITY_REPLAY_REQUIRES_HISTORY` otherwise, or with `IDENTITY_REPLAY_ENGINE_NATIVE_UNSUPPORTED` on a backend that owns recorded time itself, where TypeGraph captures no history to replay; Cloudflare D1 and neon-http continue to refuse identity-enabled graphs outright. +A lineage is discovered from the reference itself as well as from its current class, through the recorded `same` assertions and same-id nodes that ever tied it to one, so the history of a member that has since been deleted or split away is still returned from that member.

A `beforeRecorded` beyond the revision the graph's next commit will take is refused with `IDENTITY_PRUNE_BEYOND_RECORDED_CLOCK`, since that watermark would report history the graph has yet to record as already pruned. Archival interchange carries a `transitions` section plus the retention watermark, bumping the interchange format to `3.0`; older documents still import and validate unchanged. Restoring an archive's transitions validates shape only and never re-derives membership, every restored row is marked as such so `replay` never pairs it with a fabricated before/after, and when the destination has no identity transitions of its own yet the restore also sets its own watermark, so `replay` reports the pre-restore range honestly instead of claiming a complete history it cannot reconstruct. **Graph merge carries identity truth with fixed, reported rules.** There is no identity policy to configure. A merge three-way classifies every staged identity assertion and retraction against the target's current truth, and each one ends as a write, a `dropped` entry with a reason, or a refusal that names it: duplicate assertions of one pair reduce to one survivor (an id the target already holds, then the earliest `validFrom`, then the code-point-smallest id) with the rest reported as `identity:duplicate-assertion`; a branch that retracts a pair and re-asserts it itself lands both; branches asserting opposing relations for one pair, or one branch retracting a pair another re-asserts, fail the merge with `GRAPH_MERGE_IDENTITY_CONFLICT`.

Every part this import creates is now judged at the end through the audit's own reader.

The assertion now runs to a fixed point and settles the counts and per-row errors for every edge a purge removes. onConflict update could end a live required part's open attachment, bypassing the refusal a store edge update raises.

One residual gap remains: a composition edge dropped by canonicalization's own endpoint-deleted repointing issues no write for any per-write guard to see, so run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](https://typegraph.dev/limitations#composition-existence-existence-required). ### Breaking diff --git a/apps/docs/src/content/docs/interchange.md b/apps/docs/src/content/docs/interchange.md index b792322d1..c50368fd7 100644 --- a/apps/docs/src/content/docs/interchange.md +++ b/apps/docs/src/content/docs/interchange.md @@ -645,6 +645,21 @@ otherwise it is reported as a per-row error on the node (`error` matches the import commits — no orphan node row survives, and the rest of the import is unaffected. +"Attached" is judged on the written rows, by the same reader +`store.verifyConstraintFences()` uses, so a composition edge in the payload is +not enough on its own: an edge whose window does not attach the part (an +ended `oneActive` window), or whose whole does not exist (possible with +`validateReferences: false`), leaves the part refused.

From 400eb6950a387854a55d65a54559ded0b440d11b Mon Sep 17 00:00:00 2001 From: Paul Dlug Date: Mon, 5 Oct 2026 14:51:48 -0700 Subject: [PATCH 122/255] fix(schema): fold nested unions of bare primitives across projection spellings An earlier projection spelled .nullable() over a primitive union, and a doubly nullable primitive, as an anyOf nested in an anyOf; the current projection writes one flat type token array. The spelling fold only recognised members that were a single string token, so once the inner union folded to a token array the outer union was left as written and still diffed as an incompatible property change. The fold now accepts a member that is itself a bare token array, flattens it into the outer union in member order and collapses repeated tokens. The tuple reading is unchanged and now documented: a bare prefixItems is read as the required-arity tuple, because the earlier projection wrote a required and an optional trailing member identically, so a stored optional-trailing tuple still reads as changed. The changeset no longer claims that shape is fixed, and the removal docs say rows of a removed kind are reclaimed by materializeRemovals or an eager removal rather than at commit. ---

The earlier projection wrote it identically to the required tuple, so a bare `prefixItems` is read as the required-arity tuple and a `minItems` below the prefix length is compared exactly as before; run `migrateSchema()` once to restamp such a document.

Fixing the review schema alone would have turned the refusal into a silently dropped reopen, because the wire write projection and the replayed-artifact apply carried only validFrom and validTo. The upsert and validity-end wire shapes now carry clearValidTo (exclusive with validTo, refused by the schema when both appear), and one function projects a write's end-of-validity state onto the collection mutation for the live plan, its wire artifact and the replayed artifact alike. The changeset also stops describing a native-merge bypass for applyDurableMergePlan that the code retired. Revert check: restoring the previous src fails four of the five new regression tests (plan, plan after a JSON round trip, in-transaction apply, and the artifact write assertion); restoring only the replayed-artifact write mapping fails the three apply tests. --- .changeset/identity-reconciliation.md | 4 +- .../etc/typegraph-graph-merge.api.md | 2 + packages/typegraph/src/graph-merge/merge.ts | 40 +++--- .../typegraph/src/graph-merge/plan-schema.ts | 33 ++++- .../graph-merge/apply-path-parity.test.ts | 119 ++++++++++++++++++ 5 files changed, 175 insertions(+), 23 deletions(-) diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 0a90ff3cb..d479a86dc 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -12,7 +12,7 @@ A class-lifted `different` assertion now vetoes a candidate match at plan time on every identity-enabled merge, instead of aborting inside the commit on a database constraint.

The ceiling is now the higher of the next revision and one past the highest retained row, restored rows are deleted by the requested revision, and the retention watermark stays clamped to the destination's own axis so its later commits are never reported as pruned. --- .changeset/identity-reconciliation.md | 2 +- apps/docs/src/content/docs/errors.md | 12 +-

The tiebreaker appended only the start node's identity, so the rows one start node fans out into tied on the whole keyset and every sibling of a page's last row was skipped. And the cursor was applied as a node predicate on the start alias, which compiles every field against the start node's row, so an order key on a traversed alias repeated or dropped pages. The keyset now ends with the id of the edge each traversal matched, and the cursor is applied as the completed-match predicate, where the comparison, tuple-comparison and null-check forms it is built from resolve each field to the CTE that carries it. The start-alias prefix of the keyset is still pushed into the start filter, non-strictly, so a page does not re-read every start row before the cursor. page() and paginate() place the cursor through one function, and a page read inside batchOnce resolves an edge-alias order column to its traversal's CTE. A query with a recursive traversal keeps the start-node keyset. --- .changeset/paginate-traversal-rows.md | 10 + apps/docs/src/content/docs/queries/execute.md | 20 +- .../src/query/builder/executable-query.ts | 204 ++++++++++++------ .../src/query/compiler/predicates.ts | 37 +++- .../typegraph/src/query/execution/index.ts | 1 + .../src/query/execution/pagination.ts | 110 ++++++++++ .../paginate-traversal-fanout.test.ts | 60 ------ .../tests/backends/integration/pagination.ts | 175 +++++++++++++++ 8 files changed, 481 insertions(+), 136 deletions(-) create mode 100644 .changeset/paginate-traversal-rows.md delete mode 100644 packages/typegraph/tests/audit-probes/expansion-entry-points/paginate-traversal-fanout.test.ts diff --git a/.changeset/paginate-traversal-rows.md b/.changeset/paginate-traversal-rows.md new file mode 100644 index 000000000..ed80841c6 --- /dev/null +++ b/.changeset/paginate-traversal-rows.md @@ -0,0 +1,10 @@ +--- +"@nicia-ai/typegraph": patch +--- + +**`paginate()`, `page()` and `stream()` no longer skip or repeat rows of a traversal query.** A traversal that fans one start node out into several rows produced rows that tied on the whole keyset, so every sibling of a page's last row was skipped; and an order key on a traversed alias (`orderBy("p", "name")` after `.to("Person", "p")`, the shape the pagination guide shows) was compared against the start node's row, which repeated or dropped pages.

For deterministic offset pagination of one kind, include `id` in your ordering: diff --git a/packages/typegraph/src/query/builder/executable-query.ts b/packages/typegraph/src/query/builder/executable-query.ts index 55dfd52ab..d269c7d52 100644 --- a/packages/typegraph/src/query/builder/executable-query.ts +++ b/packages/typegraph/src/query/builder/executable-query.ts @@ -19,7 +19,9 @@ import { withRecordedRelationsPrecondition } from "../../utils/sql-errors"; import { type FieldRef, mergeEdgeKinds, + type NodePredicate, type OrderSpec, + type PredicateExpression, type QueryAst, type SelectiveField, type SortDirection, @@ -36,7 +38,7 @@ import { import { type SqlDialect } from "../dialect/types"; import { adjustOrderByForDirection, - buildCursorPredicate, + applyCursorFilters, buildPaginatedResult, buildPaginatedResultFromRows, buildSelectContext, @@ -957,10 +959,25 @@ export class ExecutableQuery< projection: { fields: [ ...ast.projection.fields, - ...(ast.orderBy ??

a/.changeset/composition.md +++ b/.changeset/composition.md @@ -8,7 +8,7 @@ **A part names the edge that realizes its attachment.** `NodeCollection.create`'s options are extracted into `NodeCreateOptions`, and `partOf` — on `create`, `bulkCreate`'s per-item options and both get-or-create entries — is a `CompositionAttachment`, `{ whole, via?, props?, validFrom?, validTo? }`, written in the same write as the node. `whole` is a node you already hold or a `{ kind, id }` reference, and only its `kind` and `id` are read, so a whole node's own properties never bleed into the attachment. On `store.nodes.` its `kind` is limited at compile time to the whole kinds the ontology declares for that part kind through `partOf` / `hasPart` (the new `CompositionWholeKinds`); when the ontology also declares a subclass or equivalence relation, or has lost its tuple type, any node kind of the graph is accepted and the runtime check decides. Any other top-level key on the attachment refuses with `ValidationError` (issue path `partOf.`) rather than being dropped. The window is validated once for every surface (canonical bounds, ordered pair), and on a `population: "oneActive"` pair, where only an open-ended edge is a membership, a stated `validTo` refuses with `ValidationError` (code `COMPOSITION_ATTACHMENT_WINDOW_BOUNDED`) instead of writing an edge that attaches nothing. The write is atomic: a dead or missing whole, an undeclared pair, a cardinality or acyclicity refusal, or a lost composition claim aborts the node create too, leaving no orphan row. Every one of those refusals is reached before the node row is written — for `bulkCreate` before any row of the batch, including a cycle or a whole-side cardinality the batch's own items would close together — so a caller that catches one inside an enclosing `store.transaction(...)` keeps nothing of the refused create. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written, and so does restoring a soft-deleted one through an entry that takes no `partOf` (`upsertById`, `bulkUpsertById`, `bulkReplaceById`) unless it still holds a live whole; `partOf` is honored on an optional-existence pair too. A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. -**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone.

The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item, and a matched item's refusal is reached before the batch creates any of its unmatched items. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. **`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` is refused the same way: a move opens the new attachment, and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction. @@ -16,7 +16,7 @@ **Deleting a composition whole cascades leaf-first through its live parts closure**, each part running through its own node-delete pipeline inside the whole's transaction, with restrict and cascade `onDelete` behaviors on non-composition edges honored per part.

Direction is derived per realizing edge kind: a `part -> whole` edge is followed reversed, a `whole -> part` (`has_*`) edge in its own direction, and a relation realized by both orientations across levels compiles to one traversal step. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the closure under a kind may span several node kinds with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows, and `expand` is not accepted on either step. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()`/`toDynamic()` for an explicit, already-resolved set of target node kinds. @@ -24,7 +24,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **`subgraph({ composition: true })` returns the complete owned unit.** `SubgraphOptions` gains `composition?: boolean | { via? }`, which closes the selected root over the composition edge kinds under its actual kind, in addition to whatever `edges` already lists; `{ via }` restricts the closure to one realizing edge kind (an edge type or its kind string) and refuses with `ConfigurationError` (`COMPOSITION_VIA_NOT_DECLARED`) when that edge realizes no composition pair under the root. A root kind declaring no composition parts contributes nothing and the read still runs; a graph declaring no composition relation at all refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED`). Because which composition edge kinds join depends on the root's runtime kind, `composition: true` widens the result's edge-key type to the graph's whole edge-kind union (the new `SubgraphResultEdgeKinds`), so every key the traversal can put in `adjacency` / `reverseAdjacency` is reachable through the result type; `composition` absent or `false` keeps the existing `edges`-list typing unchanged. The `project.edges` keys a call may name widen with the result (`SubgraphProjectFor`), so a `composition: true` read can project the composition edges it receives; an edge kind outside `edges` is still refused without it. The closure is exhaustive, bounded neither by `maxDepth` nor by the engine's 1000-hop cap on explicit traversals, so a part chain of any depth comes back whole rather than truncated, and `maxDepth` / `cyclePolicy` bound only the `edges` traversal listed alongside it.

The batch-scoped `read.subgraph()` inside `batchOnce()` compiles to one statement and cannot resolve the root's kind first, so it refuses any requested `composition` with `ConfigurationError` (`SUBGRAPH_COMPOSITION_ONE_STATEMENT_UNSUPPORTED`) before the batch runs a statement.

A created composition edge is not evidence on its own — an ended `oneActive` window, or a whole that does not exist (reachable with `validateReferences: false`), leaves the part refused. The check runs to a fixed point, so a required part attached only to a part this import refuses is refused with it, and the result counts track what was committed: each edge removed with a refused part comes off `edges.created` and is reported as its own per-row error. An `onConflict: "update"` whose `validTo` would end a live required part's open attachment is refused per row (`COMPOSITION_DETACH_REFUSED`), as the same edge update is through the store. Trusted import refuses every declared composition pair regardless of `existence` (`composition_unsupported`). Streamed import commits each chunk on its own, so a part and the edge attaching it arrive in separate transactions: `importGraphStream` refuses a graph declaring any required-existence part kind before reading a chunk, and `branch()`, `branchForEvolution()` and candidate staging clone such a graph through a single-transaction `importGraph` instead. The heterogeneous recorded upsert `tx.writeNodeUpsertBatch()` writes node rows only, so it refuses a required-existence part kind with `ConfigurationError` `HETEROGENEOUS_NODE_BATCH_UNSUPPORTED_KIND` before writing, rather than inserting a part with no whole or resurrecting one the composition cascade deleted. `store.verifyConstraintFences()` gains a `compositionExistence` family reporting any live required-existence part with no live whole, and a `composition` family reporting two or more live edges holding one part's reserved composition axis; a schema commit newly declaring `existence: "required"` on an already-populated pair runs a tightening preflight and refuses a dirty graph rather than silently admitting orphans. `planMerge` and `planMergeIncremental` report composition orphans in `MergePlanReview.compositionOrphans` under two causes: a part attached on the target to a whole the branch deletes (`cause: "deleted"`), and a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all (`cause: "unattached"`). `planMergeForEvolution()` judges both against the registry the evolution will commit. `applyMergePlan` re-verifies both inside the apply transaction and refuses with `MergeCompositionOrphanError` (`MERGE_COMPOSITION_ORPHAN`), and merge apply deletes nodes with `cascadeComposition: false` so the plan stays the authority over what apply deletes.

CompositionExistence is a literal union again, so its value list is no longer a forgotten export at every entrypoint.

Each member was also deleted against the row the plan read, so an update that committed in between left the member's current unique key claimed by a tombstone; a member's delete now reads its own pre-image. The cascade's closure and the acyclicity probe are lock-only reads and now share one fresh-snapshot assertion. A frame that does not acquire the per-graph lock itself (a nested managed write, a sibling started while a peer's acquisition is in flight) inherits the acquiring frame's token with its observed isolation instead of an evidence-free one, so the guard applies in every frame of a transaction. --- .changeset/composition.md | 2 +- .changeset/edge-kind-integrity.md | 2 +- apps/docs/src/content/docs/core-concepts.md | 11 + apps/docs/src/content/docs/limitations.md | 13 + .../typegraph/src/backend/command-contract.ts | 53 +++- packages/typegraph/src/store/acyclicity.ts | 29 +- .../store/operations/composition-cascade.ts | 67 +++-- .../src/store/operations/node-operations.ts | 32 +-- .../src/store/operations/write-transaction.ts | 88 +++++-- .../integration/composition-existence.ts | 25 ++ .../concurrent-composition-cascade.test.ts | 249 ++++++++++++++++++ .../tests/composition-cascade-pglite.test.ts | 46 ++++ .../typegraph/tests/edge-acyclicity.test.ts | 88 +++++++ 13 files changed, 607 insertions(+), 98 deletions(-) create mode 100644 packages/typegraph/tests/backends/postgres/concurrent-composition-cascade.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 6aa1c7d68..1f0c31480 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -16,7 +16,7 @@ **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed.

A whole's delete also removes the composition edge of a part that is already tombstoned, and each part's delete releases the unique keys the part holds at that moment.

That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order (a node an earlier item's cascade deleted is reported once, whichever order the batch names a part and its whole in), and the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them, and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent.

Apply now lands node and edge rows through one shared phase for the live plan and the replayed artifact. The required-existence rule is deferred for exactly the parts the plan could leave unattached and asserted for those parts once the last edge is in; edge releases (deletes, window ends) land before edge claims. Both orphan arms read the write set as an overlay on the pre-apply target: a deleted whole no longer reports a part the plan moves away, and a part the plan deletes is no longer reported as unattached.

External IRIs stay out of subsumption: they are inert references, so `Person ≡ schema:Person ≡ Individual` folds `Person` and `Individual` together without making the IRI a kind. `reconcileTypes` now reads the store's own validated `KindRegistry`, so a merge and a query can no longer disagree about which kinds are the same class, and every kind-name ordering in that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI; an equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. -**`from()`/`to()`/`fromDynamic()`/`toDynamic()` are polymorphic by default**: a query against a supertype returns its subtype rows, typed with the parent's properties, and the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect. `queryDefaults.expansion: "exact"` on `createStore(...)` restores the previous exact-kind behavior everywhere in one place; `search()`, the collection APIs (`find`, `count`, `updateWhere`, `compareAndSet`) and `subgraph({ includeKinds })` are unaffected and stay exact-kind. An explicit kind list, `from([...])`, is exact too and takes no options. An `updateWhere({ candidates })` query is an ordinary query and follows the default, and a candidate query must resolve to exactly one kind: over a kind with subclasses or `equivalentTo` kinds it is refused with `ConfigurationError` (`SET_UPDATE_CANDIDATE_MULTIPLE_KINDS_UNSUPPORTED`) unless it passes `{ expansion: "exact" }`. +**`from()`/`to()`/`fromDynamic()`/`toDynamic()` are polymorphic by default**: a query against a supertype returns its subtype rows, typed with the parent's properties, and the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect. `queryDefaults.expansion: "exact"` on `createStore(...)` restores the previous exact-kind behavior everywhere in one place; `search()`, the collection APIs (`find`, `count`, `updateWhere`, `compareAndSet`) and `subgraph({ includeKinds })` are unaffected and stay exact-kind. A parent-kind alias reads each property as the parent declares it: a subclass that omits a parent-optional property, or narrows its type, leaves that property usable in `select()` (decoded as the parent's type on every backend), `whereNode()`, `orderBy()` and `groupBy()`, and `$fulltext.matches()` is available whenever the parent kind declares a `searchable()` field. An explicit kind list, `from([...])`, is exact too and takes no options. An `updateWhere({ candidates })` query is an ordinary query and follows the default, and a candidate query must resolve to exactly one kind: over a kind with subclasses or `equivalentTo` kinds it is refused with `ConfigurationError` (`SET_UPDATE_CANDIDATE_MULTIPLE_KINDS_UNSUPPORTED`) unless it passes `{ expansion: "exact" }`. **An alias states its expansion as one option**, `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`), on `from()`/`to()`/`fromDynamic()`/`toDynamic()`. `"narrower"` expands a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf`, and types the alias untyped since no schema relationship is claimed. An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, through the same alias typing `from()` uses: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` on a kind the ontology can affect returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`; an options bag whose `expansion` is optional-typed must supply it (`expansion: bag.expansion ?? "exact"`). diff --git a/apps/docs/src/content/docs/queries/execute.md b/apps/docs/src/content/docs/queries/execute.md index 43386b1a4..86eb5861b 100644 --- a/apps/docs/src/content/docs/queries/execute.md +++ b/apps/docs/src/content/docs/queries/execute.md @@ -659,8 +659,9 @@ Both `paginate()` and `stream()` require an `orderBy()` clause: Cursor pagination and streaming automatically append the keys that identify one result row, so a sort that ties never skips or repeats a row at a page boundary.

The digest now names a frozen baseline of relations unconditionally and any later relation only once it holds rows. Copy and verification assemble the digest through one function, and a target prepared before a later relation existed is read as holding no rows in it. --- .changeset/identity-reconciliation.md | 2 +- apps/docs/src/content/docs/graph-merge.md | 4 +- .../typegraph/src/backend/graph-relations.ts | 5 + .../src/graph-merge/namespace-fork.ts | 158 ++++++++++++++--- .../tests/graph-merge/namespace-fork.test.ts | 165 ++++++++++++++++++ 5 files changed, 305 insertions(+), 29 deletions(-) diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index ca407ea21..5bc1b83b7 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -33,6 +33,6 @@ A transaction receipt's `writes.identity` gains `transitions`, counted beside an - `store.identity.transitionsOf` returns `{ transitions, nextCursor? }` rather than a bare array.

Origins and targets are now sliced against maxBindParameters and every origin slice is probed against every target slice, so a cycle whose rows fall in different statements is still found. Fragment composition no longer spreads a chunk list into call arguments. The merge plan preview reads the same unwritten-rows probe instead of a second walk that hopped through its own rows, and leaves out the edges the plan deletes, so a reversal or re-rooting inside an acyclic relation merges. --- .changeset/edge-kind-integrity.md | 4 +- apps/docs/src/content/docs/graph-merge.md | 5 +- packages/typegraph/src/graph-merge/merge.ts | 7 +- packages/typegraph/src/query/sql-fragment.ts | 24 +- packages/typegraph/src/store/acyclicity.ts | 257 +++++++++++--- packages/typegraph/src/store/recursive-cte.ts | 331 ++++++------------ .../sqlite/edge-acyclicity-query-plan.test.ts | 16 +- .../typegraph/tests/edge-acyclicity.test.ts | 150 ++++++-- .../graph-merge/edge-acyclicity-merge.test.ts | 95 ++++- packages/typegraph/tests/sql-fragment.test.ts | 17 + 10 files changed, 579 insertions(+), 327 deletions(-) diff --git a/.changeset/edge-kind-integrity.md b/.changeset/edge-kind-integrity.md index 6917b38ef..b767cf83f 100644 --- a/.changeset/edge-kind-integrity.md +++ b/.changeset/edge-kind-integrity.md @@ -6,9 +6,9 @@ The target allowance is scoped to the graph, the edge kind, the target kind and the target id, and deliberately not to the source: two permitted source kinds contend for one allowance, while equal ids under different target kinds, edge kinds or graphs never collide. `"one"` counts every non-deleted edge at the target, including edges with a validity end; `"oneActive"` counts only those whose `validTo` is unset.

The purge also settled only the created counters, so a part or edge a later duplicate row had updated stayed counted after its row was gone. The ledger now records how each row was counted. Every removed edge is reported, and the purge takes back exactly the created and updated counts this import added. The docs now state that a row refused against a part the import later purges is not judged again. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/interchange.md | 21 +- packages/typegraph/src/interchange/import.ts | 128 +++++++---- .../tests/backends/integration-test-suite.ts | 2 + .../integration/import-required-part-purge.ts | 217 ++++++++++++++++++ .../tests/backends/integration/index.ts | 1 + 6 files changed, 320 insertions(+), 51 deletions(-) create mode 100644 packages/typegraph/tests/backends/integration/import-required-part-purge.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index d55dc6e02..1f19876db 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -28,7 +28,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all.

The destination's baseline (own history, revision floor) is now read once per import through one function: at the start of importGraph's attempt and before the first chunk of importGraphStream, which carries it to the transitions chunk. --- .changeset/identity-reconciliation.md | 2 +- apps/docs/src/content/docs/identity.md | 10 ++- packages/typegraph/src/identity/index.ts | 1 + .../src/identity/service-interchange-write.ts | 49 +++++++++--- packages/typegraph/src/identity/service.ts | 2 + .../typegraph/src/identity/transition-log.ts | 12 +++ packages/typegraph/src/index.ts | 7 +- packages/typegraph/src/interchange/import.ts | 78 +++++++++++++++++- packages/typegraph/src/store/runtime-port.ts | 22 ++++- packages/typegraph/src/store/store.ts | 72 ++++++++++++----- .../tests/identity-import-hardening.test.ts | 80 ++++++++++++++++++- 11 files changed, 289 insertions(+), 46 deletions(-) diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 5bc1b83b7..1cb678c7f 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -8,7 +8,7 @@ A lineage is discovered from the reference itself as well as from its current class, through the recorded `same` assertions and same-id nodes that ever tied it to one, so the history of a member that has since been deleted or split away is still returned from that member.

Every transition a merge causes carries a `decision` naming the branch (when exactly one was merged), the root-first branch ancestry, the plan digest when a plan artifact was applied, and the review digest and source id the applier supplied. A transition caused by an identity assertion or retraction the merge applied is recorded with cause `reconcile`; one caused by a node row the merge wrote keeps the cause that names its mechanism — `detach` for a deleted class member, `fold` for a created same-ID peer — and carries the same `decision`. `merge()`, `mergeIncremental()`, `applyMergePlan()`, `applyMergePlanInTransaction()` and `applyDurableMergePlan()` order their node and identity writes the same way, so a plan that retracts an assertion and ends one endpoint's validity window lands through every one of them. A plan artifact also carries a branch's reopening of an ended node or edge window (`clearValidTo: true` on the upsert and on `review.validityEnds`), so a plan that reopens a window can be planned and applied through every one of them rather than being refused at planning. @@ -30,9 +30,5 @@ A transaction receipt's `writes.identity` gains `transitions`, counted beside an - A candidate match between two entities whose identity classes a `different` assertion holds apart no longer reaches the commit.

The bump is one-way and deployment-visible: a database stamped 5 or lower is caught up in place by the next privileged open (`createStoreWithSchema` / `createAdapterStoreWithSchema`) or an explicit `backend.adoptBaseSchema()`, and until one of those runs, a DML-only or zero-DDL runtime (`createVerifiedStore`, graph-template attach) refuses with `BaseSchemaMigrationError`, so privileged adoption must finish before those workers start. Once a database is stamped 6, a TypeGraph release that knows only version 5 or lower refuses it as newer; there is no downgrade path. A custom SQL engine profile's `BaseSchemaRuntime` gains two optional members, `identityTransitionsTableDdl` (the transition log's `CREATE TABLE` followed by its `CREATE INDEX` statements) and `identityTransitionRetentionTableDdl` (the retention watermark's `CREATE TABLE`), which back the version-6 adoption step; a profile that omits either still constructs, and version-6 adoption refuses with a `ConfigurationError` whose `details.missingDependencies` names what is missing.

Identity log: - Each transition a bulk write notes carries only the same-assertions with an endpoint in its own class. - Replay reconstructs before and after for every boundary on the diagonal coordinate store.asOfRecorded reads, instead of carrying after forward and reading at the wall clock. Not addressed: removing subClassOf/equivalentTo can still move a kindWithSubClasses claim axis away from existing claims; the audit now reports the resulting duplicates and the limitation is documented. --- .changeset/composition.md | 2 +- .changeset/identity-reconciliation.md | 4 +- .changeset/ontology-change-classification.md | 7 +- .changeset/projection-spelling-diff.md | 2 +- .changeset/typed-subsumption.md | 4 +- apps/docs/src/content/docs/identity.md | 28 +- .../docs/src/content/docs/schema-evolution.md | 49 ++- packages/typegraph/src/core/temporal.ts | 27 +- packages/typegraph/src/identity/replay.ts | 117 +++---- .../src/identity/schema-transition.ts | 5 +- .../typegraph/src/identity/service-facade.ts | 17 +- .../src/identity/service-interchange-write.ts | 2 +- .../src/identity/service-maintenance.ts | 19 +- .../src/identity/service-mutation.ts | 45 +-- .../typegraph/src/identity/transition-log.ts | 87 ++++- .../typegraph/src/registry/build-validated.ts | 36 ++- packages/typegraph/src/schema/manager.ts | 6 +- packages/typegraph/src/schema/migration.ts | 166 ++++------ .../typegraph/src/schema/ontology-change.ts | 165 ++++++---- .../src/schema/structural-subtype.ts | 297 +++++++++++++++--- packages/typegraph/src/store/claims/verify.ts | 41 ++- packages/typegraph/src/store/store.ts | 12 +- .../integration/composition-tightening.ts | 80 +++++ .../backends/integration/identity-replay.ts | 190 +++++++++++ .../integration/ontology-tightening.ts | 74 +++++ .../typegraph/tests/identity-replay.test.ts | 8 +- .../typegraph/tests/migration-diff.test.ts | 27 ++ .../typegraph/tests/ontology-change.test.ts | 22 +- .../identity-replay-exhaustive.test.ts | 5 +- .../schema-diff-projection-spelling.test.ts | 131 +++++++- .../schema-diff-subsumption-gate.test.ts | 92 +++++- .../schema-legacy-composition-upgrade.test.ts | 157 +++++++++ .../tests/structural-subtype.test.ts | 196 ++++++++++++ 33 files changed, 1745 insertions(+), 375 deletions(-) create mode 100644 packages/typegraph/tests/schema-legacy-composition-upgrade.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 57593a2d6..4040f4c79 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -32,7 +32,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a ### Breaking -- `partOf` / `hasPart` require `via`, in a third options argument naming the realizing edge kind.

The stored side is a delta input no store reads or writes through, so it is excused from the two contracts that postdate documents already stored — structural subsumption, and the `partOf`/`hasPart` declaration rules (a relation with no `via`, or a realizing edge those rules refuse) — which is what lets a fix-forward commit that corrects or removes the offending relation be classified at all.

There is no cascade preview API in this release; read the closure ahead of time with `store.subgraph(id, { edges: [], composition: true })`, and pass `temporalMode: "includeEnded"` when the cascade may reach a part whose `population: "one"` attachment has ended, which a current read leaves out. **`QueryBuilder` gains `parts()` and `wholes()`**, declared-structure sugar over the recursive `Traversal` AST for a declared composition relation. `parts("alias", { from?, maxHops?, depth?, path? })` derives the edge kind(s) and direction(s) from the registry's composition relation and recurses to the full transitive closure by default; pass `maxHops: 1` for the direct level only. `wholes()` is the mirror, returning the ancestor chain. Direction is derived per realizing edge kind: a `part -> whole` edge is followed reversed, a `whole -> part` (`has_*`) edge in its own direction, and a relation realized by both orientations across levels compiles to one traversal step. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the closure under a kind may span several node kinds with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows, and `expand` is not accepted on either step. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()`/`toDynamic()` for an explicit, already-resolved set of target node kinds. A related defect is fixed: a recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set (`{ expand: "inverse" }`, or the mixed-orientation case `parts()`/`wholes()` now exercise) emitted SQL that PostgreSQL rejected and SQLite accepted. Such traversals now compile and run on both dialects. -**`subgraph({ composition: true })` returns the complete owned unit.** `SubgraphOptions` gains `composition?: boolean | { via? }`, which closes the selected root over the composition edge kinds under its actual kind, in addition to whatever `edges` already lists; `{ via }` restricts the closure to one realizing edge kind (an edge type or its kind string) and refuses with `ConfigurationError` (`COMPOSITION_VIA_NOT_DECLARED`) when that edge realizes no composition pair under the root. A root kind declaring no composition parts contributes nothing and the read still runs; a graph declaring no composition relation at all refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED`). Because which composition edge kinds join depends on the root's runtime kind, `composition: true` widens the result's edge-key type to the graph's whole edge-kind union (the new `SubgraphResultEdgeKinds`), so every key the traversal can put in `adjacency` / `reverseAdjacency` is reachable through the result type; `composition` absent or `false` keeps the existing `edges`-list typing unchanged. The `project.edges` keys a call may name widen with the result (`SubgraphProjectFor`), so a `composition: true` read can project the composition edges it receives; an edge kind outside `edges` is still refused without it. The closure is exhaustive, bounded neither by `maxDepth` nor by the engine's 1000-hop cap on explicit traversals, so a part chain of any depth comes back whole rather than truncated, and `maxDepth` / `cyclePolicy` bound only the `edges` traversal listed alongside it. It is delivered or refused, never partial: a closure statement the database cut short (a `statement_timeout`, a cancelled query) refuses with `ConfigurationError` (`COMPOSITION_UNIT_INDETERMINATE`) naming the root. `tx.subgraph()` accepts and honors `composition` the same way, reading through the transaction's session, so the transaction context's `subgraph` signature gains the same `C` type parameter as `store.subgraph()`. The batch-scoped `read.subgraph()` inside `batchOnce()` compiles to one statement and cannot resolve the root's kind first, so it refuses any requested `composition` with `ConfigurationError` (`SUBGRAPH_COMPOSITION_ONE_STATEMENT_UNSUPPORTED`) before the batch runs a statement.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair. Subsumption stays strict — a kind is never its own subclass, and `expandSubClasses` still lists each kind once. External IRIs stay out of subsumption: they are inert references, so `Person ≡ schema:Person ≡ Individual` folds `Person` and `Individual` together without making the IRI a kind. `reconcileTypes` now reads the store's own validated `KindRegistry`, so a merge and a query can no longer disagree about which kinds are the same class, and every kind-name ordering in that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI; an equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. diff --git a/apps/docs/src/content/docs/identity.md b/apps/docs/src/content/docs/identity.md index d0a0b3c6d..afe12eb9e 100644 --- a/apps/docs/src/content/docs/identity.md +++ b/apps/docs/src/content/docs/identity.md @@ -735,17 +735,21 @@ with a fabricated before/after reconstructed from the destination's own, unrelated state.

How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` is refused the same way: a move opens the new attachment, and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction, one item at a time in the order given; a refusal partway through throws with the earlier items already moved, which the batch's own transaction rolls back but an enclosing `store.transaction(...)` keeps if the caller catches the error and commits. +**`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at.

How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the instant's only spelling: `reparent` takes no `validFrom`, and stating one is a compile error and a `ValidationError` at runtime. `validTo` is refused the same way: a move opens the new attachment, and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts — `existence: "required"` governs bare creation and detachment, not whole deletion. `CompositionExistenceError.code` names the situation: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which optional detail fields are populated, so a handler may branch on either. diff --git a/apps/docs/src/content/docs/ontology.md b/apps/docs/src/content/docs/ontology.md index 48413c9cc..6d2e02bb7 100644 --- a/apps/docs/src/content/docs/ontology.md +++ b/apps/docs/src/content/docs/ontology.md @@ -496,12 +496,12 @@ await store.nodes.Chapter.reparent(chapter.id, { `via` and `props` as `create`'s `partOf`: a realizing edge whose schema has required fields needs them restated on every move.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair.

An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, through the same alias typing `from()` uses: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` on a kind the ontology can affect returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`; an options bag whose `expansion` is optional-typed must supply it (`expansion: bag.expansion ??

Every write path that can put an edge into that relation — `create`, `bulkCreate`, upsert and `getOrCreateByEndpoints`, resurrection into the live population, validating import, and merge apply — is refused with the new `EdgeAcyclicityError` when the new edge's `to` endpoint already reaches its `from` endpoint; a self-loop is a cycle of length one and is refused by the same rule. A batch (`bulkCreate`, `bulkInsert`, `bulkUpsertById`, `bulkGetOrCreateByEndpoints`) is checked as a whole before its first row is written, including a cycle two of its own rows close through each other, so a refusal caught inside an enclosing `store.transaction(...)` leaves none of the batch stored. A batch of any size is checked: the probe is sent in as many statements as the backend's `maxBindParameters` requires and still sees a cycle whose rows fall in different statements. The check is exhaustive, with no depth bound, so a cycle of any length is found. Non-deleted edges count regardless of their validity window, so ending an edge's window does not free the relation while soft-deleting it does. Two concurrent writers of `a → b` and `b → a` serialize and exactly one commits. On PostgreSQL that guarantee is between `READ COMMITTED` writers: a `SERIALIZABLE` transaction is accepted but is arbitrated only against other `SERIALIZABLE` transactions, so one acyclic relation should be written at one isolation level. A backend with no transactions cannot enforce the rule at all and refuses the write with `CONSTRAINT_WRITE_FENCE_UNSUPPORTED` and the new `details.constraint` value `edgeAcyclicity`, rather than enforcing it only when nothing races; a `REPEATABLE READ` session, which cannot observe a commit that landed while it waited, is refused with `EDGE_ACYCLICITY_REQUIRES_FRESH_SNAPSHOT` in every frame of its transaction; and a statement the engine cuts short raises the new `EdgeAcyclicityIndeterminateError`, so an incomplete search is never reported as "no cycle". `store.verifyConstraintFences()` gains an `edgeAcyclicity` family reporting edges already on a cycle. `trustedImportGraphStream` refuses a store declaring an acyclic edge kind (`reason: "acyclicity_unsupported"`); the portable validating import checks each row as it writes and rolls it back per-row on a cycle. -**Graph merge catches a would-be cycle at plan time.** `merge()`, `mergeAgainstBase()`, `planMerge()`, `planMergeIncremental()` and `mergeIncremental()` all check reachability over the resolved plan's projected edge writes, after canonicalization and repointing, layered onto the target's current live edges less the edges the same plan deletes — including a cycle formed entirely from rows the plan proposes, with nothing live yet, which was not previously detectable. A plan that reverses or re-roots edges of an acyclic relation is therefore judged by the DAG it produces and merges. A violation is the new typed `AcyclicityMergeConflictError` (code `GRAPH_MERGE_ACYCLICITY_CONFLICT`), carrying the offending relation name and every edge on the cycle (`edgeId`/`edgeKind`/`fromKind`/`fromId`/`toKind`/`toId`) in `details`, so a `planMerge()` review surfaces it before anything is written.

A cycle that only appears from a write racing the plan is still caught at apply time as `MergeConstraintConflictError` wrapping `EdgeAcyclicityError`. On PostgreSQL the isolation caveat above applies to that apply-time check too: a merge into a store opened without `history: true` commits at `SERIALIZABLE`, so a `READ COMMITTED` writer that commits after the merge transaction's snapshot is not seen by it. **`defineGraph` refuses an integrity option stated outside its domain.** An unknown `cardinality`, a `targetCardinality` other than `"many"`, `"one"` or `"oneActive"`, an `endpointExistence` other than `"notDeleted"`, `"currentlyValid"` or `"ever"`, and a non-boolean `acyclic` raise `ConfigurationError` `EDGE_INTEGRITY_OPTION_INVALID` (`details.option`, `details.value`) at declaration.

A valid row that collided with it (the same unique value) was refused against a row the import then deleted, and the outcome depended on which came first in the document. Import now settles, before its first write, which required parts nothing can attach: no composition edge in the payload names the part and the target holds no attachment for it. A row that would create one is refused unwritten on both create legs, so no other row is judged against it and an edge already on the target is left alone. A part some payload edge names is still written and judged on the written rows. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/interchange.md | 31 +-- packages/typegraph/src/interchange/import.ts | 134 ++++++++++++- .../integration/import-required-part-purge.ts | 179 +++++++++++++----- .../composition-existence-import.test.ts | 68 +++++-- 5 files changed, 331 insertions(+), 83 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index 1f19876db..a5186e69a 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -28,7 +28,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all.

Regenerate the API reports, record the one newly forgotten export, add surface-exception entries for the internal registry, introspector and runtime-port members that moved, and stop exporting a schema-manager helper nothing outside the module calls. --- .../typegraph/etc/api-surface-exceptions.json | 448 ++++++++++++++++++ ...pters-drizzle-postgres-working-copy.api.md | 19 +- .../etc/typegraph-graph-merge.api.md | 19 +- .../etc/typegraph-interchange.api.md | 19 +- .../etc/typegraph-postgres-pglite.api.md | 19 +- .../typegraph/etc/typegraph-profiler.api.md | 19 +- .../typegraph/etc/typegraph-provenance.api.md | 19 +- .../typegraph/etc/typegraph-schema.api.md | 3 + .../etc/typegraph-sqlite-local.api.md | 19 +- packages/typegraph/etc/typegraph.api.md | 19 +- packages/typegraph/scripts/api-report.ts | 36 +- packages/typegraph/src/schema/manager.ts | 4 +- packages/typegraph/src/store/store.ts | 1 - 13 files changed, 610 insertions(+), 34 deletions(-) diff --git a/packages/typegraph/etc/api-surface-exceptions.json b/packages/typegraph/etc/api-surface-exceptions.json index 9d94ad38a..876eecace 100644 --- a/packages/typegraph/etc/api-surface-exceptions.json +++ b/packages/typegraph/etc/api-surface-exceptions.json @@ -6630,5 +6630,453 @@ "kind": "required-member-added", "reason": "the identity transition log adds two relations, `typegraph_identity_transitions` and `typegraph_identity_transition_retention`, and a working copy allocates a physical name for each.

The veto reads the target's ledger and the `different` assertions the merge itself stages, so an assertion carried by a merged branch separates the entities it names before a scored match can fuse them, and lands with both rows.

Every transition a merge causes carries a `decision` naming the branch (when exactly one was merged), the root-first branch ancestry, the plan digest when a plan artifact was applied, and the review digest and source id the applier supplied. A transition caused by an identity assertion or retraction the merge applied is recorded with cause `reconcile`; one caused by a node row the merge wrote keeps the cause that names its mechanism — `detach` for a deleted class member, `fold` for a created same-ID peer — and carries the same `decision`. `merge()`, `mergeIncremental()`, `applyMergePlan()`, `applyMergePlanInTransaction()` and `applyDurableMergePlan()` order their node and identity writes the same way, so a plan that retracts an assertion and ends one endpoint's validity window lands through every one of them. A plan artifact also carries a branch's reopening of an ended node or edge window (`clearValidTo: true` on the upsert and on `review.validityEnds`), so a plan that reopens a window can be planned and applied through every one of them rather than being refused at planning. -One narrow, deliberate behavior change ships in how a merge ends an assertion: when two branches end the same base identity assertion at different valid-time instants, the merge commits the earliest staged `validTo` rather than whichever branch happened to be staged last.

The fold rewrites only the keywords that spell these constructs: a union member carrying any other keyword, instance data (`default`, `const`, `examples`) and unknown extension keys are compared exactly as before, so a genuine change is still reported. Two stored shapes still read as changed, because the document cannot say what was meant. A tuple with an optional trailing member (`z.tuple([a, b.optional()])`): the earlier projection wrote it identically to the required tuple, so a bare `prefixItems` is read as the required-arity tuple. And a tuple with a rest element (`z.tuple([a], rest)`): the earlier projection wrote it with no `minItems`, which is exactly how the current one writes `z.tuple([a.optional()], rest)`, so it is read as written. Beside an explicit `items`, `minItems` is always compared as stated — the current projection omits it when every prefix member is optional, so required and all-optional tuples are different schemas to both the diff and `isStructuralSubtype()`. Run `migrateSchema()` once to restamp a document holding either shape. Schema hashes are unchanged. + +### Breaking + +- `JsonSchema`, the projected schema type the `/schema` entrypoint exports, widens `items` from `JsonSchema` to `JsonSchema | boolean` and gains `prefixItems`, `minItems` and `maxItems`, because a closed tuple now projects as `items: false`. Code that reads `.items` as a schema narrows out the boolean first. diff --git a/.changeset/store-view-sealed-reads.md b/.changeset/store-view-sealed-reads.md index e9fc5879e..c999be622 100644 --- a/.changeset/store-view-sealed-reads.md +++ b/.changeset/store-view-sealed-reads.md @@ -3,3 +3,7 @@ --- **A `StoreView` read refuses a temporal coordinate its caller states instead of silently answering at the pin.** `view.subgraph()`, the ten algorithm reads (on the view and on `view.algorithms`), `view.bulkFindEdgesFrom()` / `bulkFindEdgesTo()`, `view.edges..bulkFindFrom()` / `bulkFindTo()` and the point reads (`getById`, `getByIds`, `find`, `count`, and on edges `findFrom`, `findTo`, `findByEndpoints`) omit `temporalMode`, `asOf` and `recordedAsOf` from their option types, but an untyped caller could still pass them, in the position the live collection takes its own temporal options; the view answered at the pin and dropped the stated value.

The duplicate call-site decision is gone.

A later item's refusal therefore arrived after an earlier item had already been attached, updated or resurrected, and a caller that caught the refusal inside an enclosing store.transaction(...) committed that partial batch. The batch now resolves every matched row to the leg it owes, then reaches every verdict a read can decide for the whole set under the fence before writing anything: each stated attachment is decided and the attachments are prepared together (part and whole liveness, cardinality counting the batch's earlier edges, one acyclicity probe over all of them), and each update or resurrection leg has its merged properties validated and its unique-key transitions probed in item order, a later row seeing the keys an earlier row gives up or takes. The read-free refusals of the rows the batch will create are reached up front as well, and a match whose node row has vanished joins the create batch instead of being created between two matched items. The single-item and bulk entries now classify and write an existing-row leg through one owner each, and the live-row/tombstone choice of claim transition has one owner in the claims module. Unmatched items are still created after the matched ones, so a refusal only a new row's own preparation can reach is raised after the matched items wrote; the docs state that, the concurrent-writer remainder, and the established rule for generic bulk writes: a call that owns its transaction rolls back entirely, while a refusal caught inside an enclosing transaction can keep the batch's earlier rows. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/limitations.md | 26 + apps/docs/src/content/docs/ontology.md | 30 + .../src/content/docs/performance/overview.md | 47 +- apps/docs/src/content/docs/schemas-stores.md | 9 + .../typegraph/src/store/claims/node-claims.ts | 122 +++- .../src/store/operations/node-operations.ts | 534 ++++++++++++------ .../store/operations/node-write-pipeline.ts | 60 +- .../integration/composition-attachment.ts | 363 +++++++++++- .../integration/composition-existence.ts | 39 +- 10 files changed, 1033 insertions(+), 199 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index cb19251e9..67df07e3a 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -8,7 +8,7 @@ **A part names the edge that realizes its attachment.** `NodeCollection.create`'s options are extracted into `NodeCreateOptions`, and `partOf` — on `create`, `bulkCreate`'s per-item options and both get-or-create entries — is a `CompositionAttachment`, `{ whole, via?, props?, validFrom?, validTo? }`, written in the same write as the node. `whole` is a node you already hold or a `{ kind, id }` reference, and only its `kind` and `id` are read, so a whole node's own properties never bleed into the attachment. On `store.nodes.` its `kind` is limited at compile time to the whole kinds the ontology declares for that part kind through `partOf` / `hasPart` (the new `CompositionWholeKinds`); when the ontology also declares a subclass or equivalence relation, or has lost its tuple type, any node kind of the graph is accepted and the runtime check decides. Any other top-level key on the attachment refuses with `ValidationError` (issue path `partOf.`) rather than being dropped. The window is validated once for every surface (canonical bounds, ordered pair), and on a `population: "oneActive"` pair, where only an open-ended edge is a membership, a stated `validTo` refuses with `ValidationError` (code `COMPOSITION_ATTACHMENT_WINDOW_BOUNDED`) instead of writing an edge that attaches nothing. The write is atomic: a dead or missing whole, an undeclared pair, a cardinality or acyclicity refusal, or a lost composition claim aborts the node create too, leaving no orphan row. Every one of those refusals is reached before the node row is written — for `bulkCreate` before any row of the batch, including a cycle or a whole-side cardinality the batch's own items would close together — so a caller that catches one inside an enclosing `store.transaction(...)` keeps nothing of the refused create. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written, and so does restoring a soft-deleted one through an entry that takes no `partOf` (`upsertById`, `bulkUpsertById`, `bulkReplaceById`) unless it still holds a live whole; `partOf` is honored on an optional-existence pair too.

A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`).

Pre-existing duplicates stayed, and a new node duplicating an old value was accepted because no claim had been written for it. - Removing a subClassOf / equivalentTo relation, or the kind a hierarchy's claims sit under, so that a kindWithSubClasses constraint's claims fall outside the component the kind probes. A later write then misses them. The schema tightening preflight, which every commit path already composes (ensureSchema / createStoreWithSchema, migrateSchema, Store.evolve, Store.withEvolvedTransaction, Store.removeKinds, rollbackSchema), now derives a uniqueness claim gate per affected (kind, constraint) and probes each gated kind for rows inside the commit transaction before any other check. A populated kind refuses the commit with MigrationError reason "unique-constraint-requires-empty-kind"; details.constraints names the kind, the constraint, the cause and the claim axis (plus the previous axis for a moved claim). An unpopulated kind, a kind the same commit adds, a dropped constraint, and an added relation are unaffected: a merge keeps the old axis inside the probed component, so existing claims keep fencing. "Added or reshaped" is one predicate, uniqueConstraintEnforcementChange, shared with the graph-extension classifier that already refused the same change on extension kinds; the emptiness probe is the counter and row scope Store.evolve already uses. A backend without the atomic preflight primitive refuses a gated commit with ConfigurationError UNIQUE_CONSTRAINT_CHANGE_REQUIRES_ATOMIC_BACKEND. planEvolution lists a gated kind as a require-empty requirement and no longer emits an empty ontology-tightening requirement for a gate-only delta. The re-pairing collision test moved to neighbours that sort after the siblings: with the old fixture the re-pairing also stranded both siblings' claims, which the gate now refuses first. --- .changeset/ontology-change-classification.md | 7 + apps/docs/src/content/docs/errors.md | 29 +- .../docs/src/content/docs/schema-evolution.md | 96 ++- packages/typegraph/src/errors/index.ts | 24 + .../typegraph/src/graph-extension/classify.ts | 53 +- packages/typegraph/src/index.ts | 5 + .../typegraph/src/schema/evolution-plan.ts | 26 +- packages/typegraph/src/schema/index.ts | 1 + packages/typegraph/src/schema/migration.ts | 11 +- .../typegraph/src/schema/ontology-change.ts | 5 +- .../src/schema/tightening-preflight.ts | 81 ++- .../src/schema/unique-constraint-change.ts | 36 ++ .../src/schema/uniqueness-claim-gate.ts | 200 ++++++ packages/typegraph/src/store/store.ts | 3 + .../tests/backends/integration-test-suite.ts | 2 + .../tests/backends/integration/index.ts | 1 + .../integration/ontology-tightening.ts | 21 +- .../integration/uniqueness-claim-gate.ts | 582 ++++++++++++++++++ .../schema-commit-preflight-order.test.ts | 1 + 19 files changed, 1123 insertions(+), 61 deletions(-) create mode 100644 packages/typegraph/src/schema/unique-constraint-change.ts create mode 100644 packages/typegraph/src/schema/uniqueness-claim-gate.ts create mode 100644 packages/typegraph/tests/backends/integration/uniqueness-claim-gate.ts diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md index 327a47808..12955525c 100644 --- a/.changeset/ontology-change-classification.md +++ b/.changeset/ontology-change-classification.md @@ -12,8 +12,15 @@ **Adopted evolutions and rollbacks run the same tightening preflight.** `planEvolution()` derives the tightening check from the plan's own before/after documents and lists it as an `ontology-tightening` requirement, naming the probed ontology `changes` and the newly constrained `edgeCardinalityAxes`; `withEvolvedTransaction()` runs it on the fenced caller session before the schema compare-and-swap and refuses with the same `MigrationError` `Store.evolve()` raises, so a `disjointWith`, `acyclic: true` or tighter cardinality that existing rows violate can no longer be published through a plan. `rollbackSchema()` checks the version it reactivates against the active one the same way — a rollback to a stricter version whose declarations live rows violate is refused, while a rollback that tightens nothing still flips on any backend — and refuses to reactivate a version that re-keys a populated edge kind's match identity (`reason: "edge-match-identity-rekey"`).

A resurrection leg now reads the disjointness verdict a create answers by (checkDisjointnessConstraint) and its identity fold's refusal (a read-only assertFoldable hook over the same peer validation the fold itself runs) before any item writes. The attachments of the rows the batch is about to create are counted in the same cardinality, liveness and acyclicity frame as the matched items' attachments, so a matched part and a new row that together exceed a whole's bound are refused before the matched part is attached. An item whose attachment is already held is judged once and returned as found; it no longer repeats the lock-free pre-check at write time. A new row's own non-attachment refusals (a second unique key, a disjoint kind holding its id) stay with the create batch, because a matched update in the same batch may hand it a key. The docs and changeset state what is decided up front, what is not, the extra read pass a batch pays, and that writing a composition's realizing edge through edges..bulkUpsertById or bulkGetOrCreateByEndpoints is an ordinary edge batch. The generic rule is documented where bulk writes are described: a call that owns its transaction rolls back entirely, a refusal caught inside an enclosing transaction can keep earlier rows because the operations layer has no savepoints. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/data-sync.md | 6 + apps/docs/src/content/docs/limitations.md | 24 +- apps/docs/src/content/docs/ontology.md | 44 ++- .../src/content/docs/performance/overview.md | 23 +- apps/docs/src/content/docs/schemas-stores.md | 10 +- .../src/identity/service-maintenance.ts | 105 ++++-- packages/typegraph/src/identity/service.ts | 1 + .../src/store/operations/node-operations.ts | 330 ++++++++++++++---- packages/typegraph/src/store/store.ts | 15 + .../integration/composition-attachment.ts | 162 ++++++++- .../bulk-get-or-create-batch-verdicts.test.ts | 165 +++++++++ 12 files changed, 753 insertions(+), 134 deletions(-) create mode 100644 packages/typegraph/tests/bulk-get-or-create-batch-verdicts.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 67df07e3a..e16ae468c 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -8,7 +8,7 @@ **A part names the edge that realizes its attachment.** `NodeCollection.create`'s options are extracted into `NodeCreateOptions`, and `partOf` — on `create`, `bulkCreate`'s per-item options and both get-or-create entries — is a `CompositionAttachment`, `{ whole, via?, props?, validFrom?, validTo? }`, written in the same write as the node. `whole` is a node you already hold or a `{ kind, id }` reference, and only its `kind` and `id` are read, so a whole node's own properties never bleed into the attachment. On `store.nodes.` its `kind` is limited at compile time to the whole kinds the ontology declares for that part kind through `partOf` / `hasPart` (the new `CompositionWholeKinds`); when the ontology also declares a subclass or equivalence relation, or has lost its tuple type, any node kind of the graph is accepted and the runtime check decides. Any other top-level key on the attachment refuses with `ValidationError` (issue path `partOf.`) rather than being dropped. The window is validated once for every surface (canonical bounds, ordered pair), and on a `population: "oneActive"` pair, where only an open-ended edge is a membership, a stated `validTo` refuses with `ValidationError` (code `COMPOSITION_ATTACHMENT_WINDOW_BOUNDED`) instead of writing an edge that attaches nothing. The write is atomic: a dead or missing whole, an undeclared pair, a cardinality or acyclicity refusal, or a lost composition claim aborts the node create too, leaving no orphan row. Every one of those refusals is reached before the node row is written — for `bulkCreate` before any row of the batch, including a cycle or a whole-side cardinality the batch's own items would close together — so a caller that catches one inside an enclosing `store.transaction(...)` keeps nothing of the refused create. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written, and so does restoring a soft-deleted one through an entry that takes no `partOf` (`upsertById`, `bulkUpsertById`, `bulkReplaceById`) unless it still holds a live whole; `partOf` is honored on an optional-existence pair too. A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. -**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`).

A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item and decides its matched items as a set: every verdict a read can reach for an item that matched an existing node — the attachment's (a different whole or realizing edge, differing `props` or window, a dead whole, cardinality, and acyclicity over all of the batch's attachments), and on the `ifExists: "update"` and resurrection legs the property update's validation and unique-key probes — precedes the batch's first write, so a refused batch attaches, updates and resurrects nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. Unmatched items are created after the matched ones, so a refusal only a new row's own preparation can reach (a second unique key it loses, a whole-side cardinality bound its attachment exceeds) is raised after the matched items wrote.

Three refusals stay with the write: a new row's own non-attachment refusal (a second unique key it loses, a disjoint kind holding its id), because the unmatched items are created after the matched ones and a matched update may hand them a key; an identity fold that depends on another row the same batch restores; and a concurrent writer the fence does not exclude. A batch with more than one item that owes a write, or one such item next to a new row that states an attachment, pays one extra fenced read pass for this. Bulk writes that do not state a composition attachment keep the established rule: a call that owns its transaction rolls back entirely, while a refusal caught inside an enclosing `store.transaction(...)` can keep the batch's earlier rows, because the operations layer has no savepoints. That includes writing a realizing edge directly: `edges..bulkCreate` and `bulkInsert` decide every item before writing, but `bulkUpsertById` and `bulkGetOrCreateByEndpoints` are ordinary edge batches.

The fence was a lock, and a lock cannot refresh a snapshot: a REPEATABLE READ or SERIALIZABLE session that read anything before a READ COMMITTED writer committed kept reading the graph as it was. PostgreSQL arbitrates SERIALIZABLE transactions only against each other, so the serializable session and the read-committed writer could both commit and close a cycle between them. The statement that takes the fence now also advances the graph's row in the fences relation, behind the advisory lock, and reports that it did. A session whose snapshot predates another acquirer's commit fails on that row with a serialization failure instead of deciding. The portable acquisition and the fused schema + graph fence share one spelling of the row write, and the coordination token carries the acquisition's own evidence: read committed always observes the fence's previous holders, a snapshot isolation does only when the fence row was advanced, and an unknown isolation never does. A backend whose fence is an advisory lock with no fences relation is refused at both snapshot isolations by the same predicate that previously accepted serializable. A write the store opened the transaction for is replayed whole through the existing retry owner when its fence is a keyed acquisition, including the transaction a bulk upsert opens around its resolved mutation set. Inside a caller-owned transaction the refusal propagates as a TransactionConflictError minted at the fence. Engine-serialized backends take no keyed acquisition, issue no new statement and are never retried units. REPEATABLE READ is now supported for these decisions on the bundled PostgreSQL backends, where it was refused outright. --- .changeset/composition.md | 2 +- .changeset/edge-kind-integrity.md | 9 +- apps/docs/src/content/docs/backend-setup.md | 23 +- apps/docs/src/content/docs/core-concepts.md | 33 +- apps/docs/src/content/docs/limitations.md | 21 +- apps/docs/src/content/docs/schemas-stores.md | 10 +- .../src/backend/capabilities/write-fence.ts | 175 +++++- .../typegraph/src/backend/command-contract.ts | 143 +++-- .../backend/drizzle/operation-backend-core.ts | 6 +- .../drizzle/postgres-schema-write-fence.ts | 31 +- packages/typegraph/src/backend/index.ts | 1 + packages/typegraph/src/backend/types.ts | 28 +- packages/typegraph/src/graph-merge/merge.ts | 16 +- packages/typegraph/src/index.ts | 1 + .../src/store/collections/edge-collection.ts | 11 +- .../src/store/collections/node-collection.ts | 7 +- .../src/store/operations/write-transaction.ts | 137 ++++- .../src/store/recorded-capture/clock.ts | 85 ++- .../typegraph/tests/advisory-only-backend.ts | 40 ++ .../integration/write-fence-conformance.ts | 2 +- .../concurrent-composition-cascade.test.ts | 45 +- .../concurrent-edge-acyclicity.test.ts | 12 +- .../postgres/mixed-isolation-fence.test.ts | 521 ++++++++++++++++++ .../typegraph/tests/command-contract.test.ts | 181 +++++- .../tests/composition-cascade-pglite.test.ts | 110 ++-- .../tests/constraint-write-fence.test.ts | 2 +- .../typegraph/tests/edge-acyclicity.test.ts | 96 +++- .../tests/edge-convergence-command.test.ts | 114 ++-- .../tests/lock-fence-plan-inventory.test.ts | 23 +- .../tests/postgres-fence-sql.test.ts | 63 ++- .../tests/schema-graph-write-fence.test.ts | 35 +- .../tests/snapshot-fence-retry.test.ts | 240 ++++++++ .../tests/write-plan-statement-order.test.ts | 17 +- packages/typegraph/vitest.pglite-project.ts | 1 + 34 files changed, 1935 insertions(+), 306 deletions(-) create mode 100644 packages/typegraph/tests/advisory-only-backend.ts create mode 100644 packages/typegraph/tests/backends/postgres/mixed-isolation-fence.test.ts create mode 100644 packages/typegraph/tests/snapshot-fence-retry.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index cb19251e9..e505262e4 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -16,7 +16,7 @@ **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed.

That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality.

Adding `acyclic: true` to a populated edge kind is a tightening: it is probed against live rows inside the schema-commit transaction and refused with `MigrationError` `reason: "ontology-tightening-violated"` when a cycle already exists, with `details.violations` in the shape `store.verifyConstraintFences()` returns. The classifier records that change as an `OntologyChange` with `entity: "edgeRegistration"`. `trustedImportGraphStream` refuses a store declaring an acyclic edge kind (`reason: "acyclicity_unsupported"`); the portable validating import checks each row as it writes and rolls it back per-row on a cycle. -**Graph merge catches a would-be cycle at plan time.** `merge()`, `mergeAgainstBase()`, `planMerge()`, `planMergeIncremental()` and `mergeIncremental()` all check reachability over the resolved plan's projected edge writes, after canonicalization and repointing, layered onto the target's current live edges less the edges the same plan deletes — including a cycle formed entirely from rows the plan proposes, with nothing live yet, which was not previously detectable.

A cycle that only appears from a write racing the plan is still caught at apply time as `MergeConstraintConflictError` wrapping `EdgeAcyclicityError`.

Code that builds either object literal by hand adds the field; everything produced through `defineGraph`, the serializer or `introspectSchema` is unaffected. The serializer omits `targetCardinality` when it is undeclared or explicitly the default `"many"`, so a graph that never uses the option serializes and hashes byte-identically to a pre-release document and keeps `ensureSchema`'s schema-hash fast path. Declaring a non-default value picks up a new schema hash, like any other schema change. - `GraphBackend.countEdgesFrom` and its `CountEdgesFromParams` type are replaced by `countEdgesAtEndpoint` and `CountEdgesAtEndpointParams`, whose params carry `endpoint: "from" | "to"` and the endpoint's identity as `endpointKind` / `endpointId`.

A kindWithSubClasses claim sits at the code-point minimum of the component it was written under, and a merge moves where new claims are written without moving old ones, so one kind's claims can sit at several axes. The gate compared only the axis the previous schema wrote at against the proposed component, so a merge followed by a split that dropped the older axis committed ungated and a duplicate of an old row was accepted. The gate now fires when the proposed component loses a member that sorts before the kind: a kind is always in its own component, so every axis its claims were ever written at is the kind or an earlier member, and a lost later member cannot hold them. The detail field previousAxis is replaced by lostKinds. A kind the commit adds was skipped on the ground that it cannot hold rows, but migrateSchema with discardDroppedKindRows leaves a dropped kind's rows in the table, and re-adding the kind with a unique constraint made them live again with no claim. Every constraint on an added kind now reads as added and is probed. planEvolution does not list the gate for a kind the extension already lists as new. The probe was a full COUNT(*) of the kind in the case that matters. countNodesByKind and countEdgesByKind take an optional limit that bounds the count, and schemaKindHasRows is the existence form every require-empty check now shares, the gate included. Adds cross-backend cases for merge-then-split, the discarded-drop re-add through ensureSchema, Store.evolve and an adopted plan, and the bounded count. --- .changeset/ontology-change-classification.md | 7 +- apps/docs/src/content/docs/errors.md | 10 +- .../docs/src/content/docs/schema-evolution.md | 58 ++-- .../backend/drizzle/operations/collections.ts | 47 ++- .../src/backend/schema-kind-emptiness.ts | 20 +- packages/typegraph/src/backend/types.ts | 10 + packages/typegraph/src/errors/index.ts | 5 +- .../typegraph/src/schema/evolution-plan.ts | 8 +- packages/typegraph/src/schema/manager.ts | 9 +- .../src/schema/tightening-preflight.ts | 4 +- .../src/schema/uniqueness-claim-gate.ts | 104 +++--- packages/typegraph/src/store/store.ts | 13 +- .../integration/uniqueness-claim-gate.ts | 306 +++++++++++++++++- .../tests/schema-kind-emptiness.test.ts | 76 ++++- 14 files changed, 569 insertions(+), 108 deletions(-) diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md index 12955525c..62f8da115 100644 --- a/.changeset/ontology-change-classification.md +++ b/.changeset/ontology-change-classification.md @@ -12,13 +12,14 @@ **Adopted evolutions and rollbacks run the same tightening preflight.** `planEvolution()` derives the tightening check from the plan's own before/after documents and lists it as an `ontology-tightening` requirement, naming the probed ontology `changes` and the newly constrained `edgeCardinalityAxes`; `withEvolvedTransaction()` runs it on the fenced caller session before the schema compare-and-swap and refuses with the same `MigrationError` `Store.evolve()` raises, so a `disjointWith`, `acyclic: true` or tighter cardinality that existing rows violate can no longer be published through a plan. `rollbackSchema()` checks the version it reactivates against the active one the same way — a rollback to a stricter version whose declarations live rows violate is refused, while a rollback that tightens nothing still flips on any backend — and refuses to reactivate a version that re-keys a populated edge kind's match identity (`reason: "edge-match-identity-rekey"`).

That turned a provenance read into a write, made every history-capturing and revision-tracking write update one hot row per graph, and let dead versions of that row slow every fenced writer while an older snapshot stayed open. The row is now written only by a writer that makes a decision nothing but the fence protects: an edge-acyclicity probe, a composition whole's parts closure, a match-key convergence. Every such writer advances it, at every isolation level, so a stale snapshot still fails on it with SQLSTATE 40001. Every other holder takes the lock alone, with the statement it issued before the row existed. - `lockRecordedGraphWrite` takes the keyed exclusion and the isolation fact. `lockRecordedGraphDecision` is the deciding form: the acquisition itself in one statement, or an upgrade behind a lock the transaction already holds. `fenceLockOnlyDecision` is the one gate of the acyclicity probe and the cascade closure: advance the row, then require a fresh snapshot. - A write frame takes the deciding form up front when the constraint it names decides under the lock (`CONSTRAINT_FENCE_DECIDES_UNDER_LOCK_ONLY`); the fused schema + graph fence takes `fenceRow: "advance" | "leave"`. - A merge plan applied inside a caller's transaction reads the whole target, so it must observe every earlier holder of the fence, not only the deciders: `observesEveryEarlierFenceHolder` owns that read-committed-only decision beside `observesPostFenceCommits`. - A store-owned write is replayed on a stale-snapshot refusal only when it names a constraint; `bulkGetOrCreateByConstraint` opens its transaction through the same retry seam as the bulk upserts. - `FenceStatements.acquireKeyedSnapshotFence` is absent for an advisory fence that names no fences relation. Measured on PostgreSQL 18 with one client, the fence statement alone in its own transaction: 0.11 ms lock-only, 0.17 ms advancing the row, every update heap-only. With one REPEATABLE READ transaction left open the advancing form took 0.24, 0.37, 0.50 and 0.63 ms after 20k, 40k, 60k and 80k deciding transactions while the lock-only form stayed at 0.11 ms. Revert check: with the source of the fence-row fix removed, all 16 mixed-isolation cases fail, the REPEATABLE READ merge commit included. With every holder advancing the row again, the statement-count cases of fence-row-scope and the read-only `holding()` case fail. --- .changeset/composition.md | 2 +- .changeset/edge-kind-integrity.md | 12 +- apps/docs/src/content/docs/backend-setup.md | 58 ++- apps/docs/src/content/docs/core-concepts.md | 33 +- apps/docs/src/content/docs/limitations.md | 67 +++- apps/docs/src/content/docs/provenance.md | 6 + apps/docs/src/content/docs/schemas-stores.md | 7 +- .../src/backend/capabilities/write-fence.ts | 82 ++-- .../typegraph/src/backend/command-contract.ts | 47 ++- .../backend/drizzle/operation-backend-core.ts | 5 +- .../backend/drizzle/operations/strategy.ts | 3 +- .../drizzle/postgres-schema-write-fence.ts | 63 ++- packages/typegraph/src/backend/types.ts | 43 +- packages/typegraph/src/graph-merge/merge.ts | 8 +- .../typegraph/src/graph-merge/write-fence.ts | 33 +- packages/typegraph/src/store/acyclicity.ts | 32 +- .../typegraph/src/store/claims/backing.ts | 30 ++ .../src/store/collections/node-collection.ts | 15 +- .../store/operations/composition-cascade.ts | 22 +- .../src/store/operations/write-transaction.ts | 83 ++-- .../typegraph/src/store/recorded-capture.ts | 1 + .../src/store/recorded-capture/clock.ts | 233 ++++++++--- .../concurrent-composition-cascade.test.ts | 5 +- .../postgres/mixed-isolation-fence.test.ts | 150 ++++++- .../postgres/provenance-advisory-lock.test.ts | 63 +++ .../typegraph/tests/command-contract.test.ts | 15 + .../typegraph/tests/fence-row-scope.test.ts | 374 ++++++++++++++++++ .../graph-merge/fresh-snapshot-fence.test.ts | 57 ++- .../tests/lock-fence-plan-inventory.test.ts | 2 +- .../tests/postgres-fence-sql.test.ts | 49 +-- .../tests/schema-graph-write-fence.test.ts | 49 ++- .../tests/snapshot-fence-retry.test.ts | 99 ++++- packages/typegraph/vitest.pglite-project.ts | 1 + 33 files changed, 1442 insertions(+), 307 deletions(-) create mode 100644 packages/typegraph/tests/fence-row-scope.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index e505262e4..bca1af46c 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -16,7 +16,7 @@ **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed.

That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order (a node an earlier item's cascade deleted is reported once, whichever order the batch names a part and its whole in), and the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them, and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent.

The uniqueness claim gate built the previous schema's registry with the relaxed declaration rules at a second call site, which the construction ratchet allows at exactly one. The schema diff now owns that build in buildSchemaBaselineRegistry, and the tightening preflight calls it. FenceStatements.acquireKeyedSnapshotFence is optional rather than required-and-undefined, so a hand-authored FenceStatements stays valid and reads as a fence that cannot advance a fence row, which the deciding writes already refuse at snapshot isolation. The API ledgers and the forgotten-export pins are regenerated for the merged surface: SchemaGraphWriteFenceParams and GraphWriteFenceAcquisition are the only names that moved a pin. --- .changeset/edge-kind-integrity.md | 2 +- .../typegraph-adapters-drizzle-engine.api.md | 18 ++++- ...ph-adapters-drizzle-postgres-pglite.api.md | 15 +++- ...pters-drizzle-postgres-working-copy.api.md | 18 ++++- ...typegraph-adapters-drizzle-postgres.api.md | 15 +++- ...raph-adapters-drizzle-sqlite-libsql.api.md | 15 +++- ...graph-adapters-drizzle-sqlite-local.api.md | 15 +++- .../typegraph-adapters-drizzle-sqlite.api.md | 15 +++- .../typegraph/etc/typegraph-backend.api.md | 18 ++++- .../etc/typegraph-graph-merge.api.md | 18 ++++- .../etc/typegraph-interchange.api.md | 18 ++++- .../etc/typegraph-postgres-pglite.api.md | 18 ++++- .../typegraph/etc/typegraph-profiler.api.md | 18 ++++- .../typegraph/etc/typegraph-provenance.api.md | 18 ++++- .../typegraph/etc/typegraph-schema.api.md | 29 +++++++- .../etc/typegraph-sqlite-local.api.md | 18 ++++- packages/typegraph/etc/typegraph.api.md | 42 ++++++++++- packages/typegraph/scripts/api-report.ts | 71 ++++++++++--------- .../src/backend/capabilities/write-fence.ts | 2 +- .../typegraph/src/schema/ontology-change.ts | 31 +++++--- .../src/schema/tightening-preflight.ts | 7 +- 21 files changed, 352 insertions(+), 69 deletions(-) diff --git a/.changeset/edge-kind-integrity.md b/.changeset/edge-kind-integrity.md index c4593ad58..cb9337a48 100644 --- a/.changeset/edge-kind-integrity.md +++ b/.changeset/edge-kind-integrity.md @@ -20,7 +20,7 @@ Schema serialization, hashing, introspection, runtime graph extensions and schem - At `REPEATABLE READ` or `SERIALIZABLE`, such a PostgreSQL write now fails with SQLSTATE `40001` on that row when another such writer committed past its snapshot, reported as `TransactionConflictError` with the driver error as `cause`. Retry the whole transaction, as for any serialization failure. - A PostgreSQL collection write or import that names a constraint, in a transaction TypeGraph opened, and every `bulkUpsertById` and `bulkGetOrCreateByConstraint`, is now replayed up to three times on a serialization failure or deadlock and raises `TransactionConflictError` once the attempts are spent, where the driver error previously propagated from the first failure. A write that names no constraint takes one attempt, as before. SQLite is unchanged. - `getOrCreateByEndpoints` and `bulkGetOrCreateByEndpoints` now accept a `REPEATABLE READ` create leg on the bundled PostgreSQL backends, where it was refused with `MATCH_KEY_CONVERGENCE_REQUIRES_FRESH_SNAPSHOT`. A custom backend whose fence is an advisory lock with no fences relation (`tableNames.fences`) is now refused at `SERIALIZABLE` as well as `REPEATABLE READ`, with the same code, where `SERIALIZABLE` was previously accepted. -- `GraphBackend.lockSchemaVersionAndGraphWrite` resolves the new `GraphWriteFenceAcquisition` (`{ isolation, fenceRow: "advanced" | "none" }`) instead of a bare `GraphCommandIsolation`.

Its params gain a required `fenceRow: "advance" | "leave"`: a custom backend implementing it advances the graph's fence row only for `"advance"`, and reports `fenceRow: "advanced"` only when its statement did. `FenceStatements` gains the optional `acquireKeyedSnapshotFence`, which is absent for an advisory fence that names no fences relation; a fence without it cannot advance a fence row, so the deciding writes above are refused on it at `REPEATABLE READ` and `SERIALIZABLE`. - `EdgeRegistration` gains `targetCardinality?`, `EdgeIntrospection` gains a required `targetCardinality` and a required `acyclic` boolean (`false` unless declared), and `SerializedEdgeDef` gains an optional `targetCardinality?`. Code that builds either object literal by hand adds the field; everything produced through `defineGraph`, the serializer or `introspectSchema` is unaffected. The serializer omits `targetCardinality` when it is undeclared or explicitly the default `"many"`, so a graph that never uses the option serializes and hashes byte-identically to a pre-release document and keeps `ensureSchema`'s schema-hash fast path. Declaring a non-default value picks up a new schema hash, like any other schema change. - `GraphBackend.countEdgesFrom` and its `CountEdgesFromParams` type are replaced by `countEdgesAtEndpoint` and `CountEdgesAtEndpointParams`, whose params carry `endpoint: "from" | "to"` and the endpoint's identity as `endpointKind` / `endpointId`. A custom backend renames its implementation and reads the endpoint discriminant. - `ClaimEdgeCardinalityParams` gains a required `direction: "source" | "target"` discriminant, and `EdgeCardinalityDeclaration` / `ContendedEdgeRow` gain the same. Source-side claim axis strings are byte-identical to before, so existing `typegraph_edge_claims` rows keep fencing what they fence today and no migration is required. diff --git a/packages/typegraph/etc/typegraph-adapters-drizzle-engine.api.md b/packages/typegraph/etc/typegraph-adapters-drizzle-engine.api.md index 00b5a0b26..d1d4d5a6c 100644 --- a/packages/typegraph/etc/typegraph-adapters-drizzle-engine.api.md +++ b/packages/typegraph/etc/typegraph-adapters-drizzle-engine.api.md @@ -507,7 +507,7 @@ type CommonOperationStrategy = Readonly<{ buildDisjointOverlapAudit: (graphId: string, kinds: readonly [string, string]) => SQL;

A role that performs those writes needs `INSERT` and `UPDATE` on that table. Every other holder of the fence — a history-capturing or revision-tracking write, a cardinality, uniqueness or disjointness write, a provenance `holding()` read — takes the lock alone, writes no row and issues the statements it issued before. The row is updated once per deciding transaction, so while a transaction holding an older snapshot stays open (`pg_dump`, a long report, an idle-in-transaction session) its dead versions accumulate and those deciding writes slow until the snapshot closes and the table is vacuumed; see "Write Fence Row" in the limitations guide. +- A `store.transaction` whose callback holds a raw SQL handle (`tx.sqlAvailability: "available"`) now takes the per-graph write fence at every constraint-fenced write instead of once per transaction. A `ROLLBACK TO SAVEPOINT` issued through `tx.sql` releases an advisory lock taken after that savepoint and undoes a fence-row advance made after it, so a later fenced write in the same transaction previously ran under a lock it no longer held. Transactions without the handle (history capture, revision tracking, or no native transaction) still take the fence once. - At `REPEATABLE READ` or `SERIALIZABLE`, such a PostgreSQL write now fails with SQLSTATE `40001` on that row when another such writer committed past its snapshot, reported as `TransactionConflictError` with the driver error as `cause`. Retry the whole transaction, as for any serialization failure. - A PostgreSQL collection write or import that names a constraint, in a transaction TypeGraph opened, and every `bulkUpsertById` and `bulkGetOrCreateByConstraint`, is now replayed up to three times on a serialization failure or deadlock and raises `TransactionConflictError` once the attempts are spent, where the driver error previously propagated from the first failure. A write that names no constraint takes one attempt, as before. SQLite is unchanged. - `getOrCreateByEndpoints` and `bulkGetOrCreateByEndpoints` now accept a `REPEATABLE READ` create leg on the bundled PostgreSQL backends, where it was refused with `MATCH_KEY_CONVERGENCE_REQUIRES_FRESH_SNAPSHOT`. A custom backend whose fence is an advisory lock with no fences relation (`tableNames.fences`) is now refused at `SERIALIZABLE` as well as `REPEATABLE READ`, with the same code, where `SERIALIZABLE` was previously accepted. diff --git a/apps/docs/src/content/docs/limitations.md b/apps/docs/src/content/docs/limitations.md index 0213280bb..00a6f39e9 100644 --- a/apps/docs/src/content/docs/limitations.md +++ b/apps/docs/src/content/docs/limitations.md @@ -404,7 +404,10 @@ Consequences of the row being a real write: transaction or under a `SELECT`-only role. - **A long-lived snapshot slows those deciding writes.** The row is updated once per deciding transaction (once per deciding write in a transaction you - adopted with `withTransaction`), and PostgreSQL cannot remove the dead + adopted with `withTransaction`, or in a `store.transaction` whose + `tx.sqlAvailability` is `"available"`: raw SQL can roll back to a savepoint + and undo both the lock and the row advance, so each fenced write there takes + the fence again), and PostgreSQL cannot remove the dead versions an open snapshot might still need.

An added edge kind is now probed as if its previous declaration admitted every pair and declared no acyclicity, after one emptiness read so a kind with no rows costs nothing more. --- .../backend/drizzle/operation-backend-core.ts | 22 +-- .../operations/constraint-fence-audit.ts | 43 +++-- .../backend/drizzle/operations/strategy.ts | 3 - .../typegraph/src/schema/ontology-change.ts | 50 +++++- .../src/schema/tightening-preflight.ts | 74 ++++++++- .../constraint-fence-verification.ts | 56 ++++--- .../integration/ontology-tightening.ts | 157 ++++++++++++++++++ 7 files changed, 342 insertions(+), 63 deletions(-) diff --git a/packages/typegraph/src/backend/drizzle/operation-backend-core.ts b/packages/typegraph/src/backend/drizzle/operation-backend-core.ts index ddd9d2315..35d0c70ee 100644 --- a/packages/typegraph/src/backend/drizzle/operation-backend-core.ts +++ b/packages/typegraph/src/backend/drizzle/operation-backend-core.ts @@ -1085,10 +1085,9 @@ function pairAtomicMutationChunksWithIds( }); } -// `graphId`, `edgeKind`, and `now` (bound twice, once per side of the -// current-window predicate) are fixed per statement; each admitted pair -// costs two more (`fromKind`, `toKind`). -const MISASSIGNED_EDGE_ENDPOINT_FIXED_PARAM_COUNT = 4; +// `graphId` and `edgeKind` are fixed per statement; each admitted pair costs +// two more (`fromKind`, `toKind`). +const MISASSIGNED_EDGE_ENDPOINT_FIXED_PARAM_COUNT = 2; const MISASSIGNED_EDGE_ENDPOINT_PAIR_PARAM_COUNT = 2; /** @@ -1161,7 +1160,6 @@ async function readMisassignedEdgeEndpointRows( operationStrategy: CommonOperationStrategy, graphId: string, allowance: EdgeEndpointAllowance, - now: string, pairChunkSize: number, ): Promise { const pairChunks = @@ -1174,7 +1172,6 @@ async function readMisassignedEdgeEndpointRows( operationStrategy.buildMisassignedEdgeEndpointAudit( graphId, allowance.edgeKind, - now, pairChunk, ), ); @@ -1948,7 +1945,10 @@ export function createCommonOperationBackend( holder_edge_id: string; }>(lockQuery); const holderByTarget = new Map( - rows.map((row) => [claimTargetKey(row.axis, row.key), row.holder_edge_id]), + rows.map((row) => [ + claimTargetKey(row.axis, row.key), + row.holder_edge_id, + ]), ); const incumbentByTarget = await readClaimlessIncumbents(chunk); for (const entry of chunk) { @@ -5354,7 +5354,7 @@ export function createCommonOperationBackend( } return edgeRows; }, - }), + }), ...(buildFindEdgesAcrossKinds === undefined ? {} @@ -5680,11 +5680,6 @@ export function createCommonOperationBackend( // meaningful. const misassignedEdgeEndpointRows: MisassignedEdgeEndpointRow[] = []; if (params.edgeEndpointAllowances !== undefined) { - // One instant for the whole family: every chunk of every allowance - // in this call reads against the same "current" window, exactly as - // `withPinnedReadInstant` pins one instant across the operands of a - // set operation (`src/query/compiler/temporal.ts`). - const now = nowIso(); const pairChunkSize = misassignedEdgeEndpointPairChunkSize(maxBindParameters); for (const allowance of params.edgeEndpointAllowances) { @@ -5693,7 +5688,6 @@ export function createCommonOperationBackend( operationStrategy, params.graphId, allowance, - now, pairChunkSize, )) { misassignedEdgeEndpointRows.push(row); diff --git a/packages/typegraph/src/backend/drizzle/operations/constraint-fence-audit.ts b/packages/typegraph/src/backend/drizzle/operations/constraint-fence-audit.ts index 8d8825815..4fbd2be4d 100644 --- a/packages/typegraph/src/backend/drizzle/operations/constraint-fence-audit.ts +++ b/packages/typegraph/src/backend/drizzle/operations/constraint-fence-audit.ts @@ -24,7 +24,7 @@ import { } from "../../../store/claims/edge-claims"; import type { CompositionClaimScope } from "../../types"; import { claimHolderTerms, endpointTerms } from "./edge-claims"; -import { currentWindowPredicate, quotedColumn, type Tables } from "./shared"; +import { quotedColumn, type Tables } from "./shared"; /** The alias the correlated subquery reads the same relation under. */ const PEER = "peer"; @@ -45,6 +45,23 @@ function inList(values: readonly string[]): SQL { ); } +/** + * THE population a row-shape audit family reads: every row that is not + * tombstoned, whatever its validity window.

The registry's subClassOf/equivalentTo check compared that projection, so it accepted a case-insensitive child under a case-sensitive parent, a child under a refined or strict parent it does not satisfy, and a child whose .meta({ maxLength }) only looked constrained. A live graph's check now compares a projection that marks each such node, keyed by the Zod instance that carries it, and the comparator answers incomparable for a marker on either side (flags, meta) or on the parent (refinement, strict object). A child reusing the parent's schema, or a field schema both share, still compares equal. The persisted projection and the schema hash are unchanged. Also corrects the UNIQUE_CONSTRAINT_CHANGE_REQUIRES_ATOMIC_BACKEND entry in errors.md (a newly added kind is gated too), documents that adding an edge kind owes the ontology preflight, and lists the new refusals in the changeset. --- .changeset/ontology-change-classification.md | 8 +- apps/docs/src/content/docs/errors.md | 4 +- packages/typegraph/src/registry/builders.ts | 10 +- .../validate-structural-subsumption.ts | 13 +- .../schema/structural-subtype-projection.ts | 163 ++++++++++++++++++ .../src/schema/structural-subtype.ts | 45 ++++- .../structural-subtype-zod-projection.test.ts | 162 +++++++++++++++++ 7 files changed, 391 insertions(+), 14 deletions(-) create mode 100644 packages/typegraph/src/schema/structural-subtype-projection.ts create mode 100644 packages/typegraph/tests/structural-subtype-zod-projection.test.ts diff --git a/.changeset/ontology-change-classification.md b/.changeset/ontology-change-classification.md index 62f8da115..1da808aea 100644 --- a/.changeset/ontology-change-classification.md +++ b/.changeset/ontology-change-classification.md @@ -2,11 +2,11 @@ "@nicia-ai/typegraph": minor --- -**`isStructuralSubtype(child, parent)`** joins the `@nicia-ai/typegraph/schema` entrypoint: a structural-subtyping check over TypeGraph's projected JSON Schema fragment that answers whether every value satisfying `child` is guaranteed to satisfy `parent`.

The registry's `subClassOf` / `equivalentTo` check additionally reads the live Zod schema for the constraints the JSON Schema projection drops — a regex flag other than `g`, a `.meta()` key spelled like a constraining keyword, and, on the parent, a refinement or a strict object — and answers `incomparable` for a pair that carries one where the two sides differ. A `$ref` is resolved against its own side's `$defs`: two properties that name the same reference are the same schema only when the definitions they reach are equal, since the projection numbers a recursive definition by encounter order and two unrelated recursive types share a name. A parent `oneOf` is read member-wise only when no value can match two members (different `type` tokens, or one required property pinned to disjoint `const`/`enum` sets): `z.discriminatedUnion` always qualifies, while a `z.xor` whose members overlap is `incomparable`.

It answers a different question from the migration classifier's `isBreakingPropertyChange`, which asks whether existing rows stay valid after a schema edit; the two disagree in both directions and the module documents why. It is the predicate this release's typed `subClassOf` / `equivalentTo` contract is built on. **Ontology changes are now classified by what they do to existing data**, and a tightening the data violates is refused instead of auto-migrated. Adding `disjointWith`, `subClassOf` or `equivalentTo` is classified `warning` and probed inside the schema-commit transaction — before the Operational Identity closure rebuild — on every path that commits a version (`createStoreWithSchema` / `ensureSchema`, `Store.evolve()`, `migrateSchema()`, `Store.withEvolvedTransaction()`, and `rollbackSchema()`). An added `subClassOf`/`equivalentTo` is probed for the uniqueness components it merges — including a re-pairing where each kind swaps one neighbour for another, so no component grows — and for the kinds it makes required-existence composition parts: a live row of a kind that inherits `existence: "required"` with no live whole refuses the commit (`compositionExistence`). Removing `subClassOf`/`equivalentTo` is probed for live edges whose endpoints the remaining declarations no longer admit. Adding or removing `inverseOf` or `implies` is now `breaking`: both change what a default `expand` traversal returns, so they need an explicit `migrateSchema()`, exactly like the Operational Identity `sameIdAcrossKinds` flip. Adding `partOf`/`hasPart` is `warning`, probed for a part with more than one live whole and for a composition cycle (plus a part with no live whole when the pair is `existence: "required"`); removing one is `breaking`, like `inverseOf`/`implies` — except a stored relation with no `via`, which realizes no composition pair and is `safe` to remove. Removing `disjointWith` stays `safe`, and `broader`/`narrower`/`relatedTo`/`differentFrom` stay `safe` in both directions. A relation whose `from` or `to` names a kind the same commit removes is itself `safe`, and rows of the removed kind never block the commit. An edge kind that stops admitting an endpoint pair between surviving kinds is probed the same way whatever caused the loss — a removed `subClassOf`/`equivalentTo`, a narrowed `from`/`to` declaration (reported as an `entity: "edgeRegistration"` change), or a kind removed from the middle of a subclass chain — so `Store.removeKinds()` refuses when a surviving subclass's live edge was admitted only through the removed kind. `ChangeSeverity` itself is unchanged — `warning` now means "auto-migrates only if the data allows it". -**A refused tightening throws `MigrationError`** with `details.reason: "ontology-tightening-violated"` and `details.violations` in exactly the shape `store.verifyConstraintFences()` returns, so the same rows that block the migration can be listed, resolved, and the migration retried. The audit gains an `edgeEndpointAssignability` family reporting live edges sitting outside every declared endpoint pair. A backend implementing `readConstraintFenceViolations` may receive an `edgeEndpointAllowances` declaration and must answer with `misassignedEdgeEndpointRows`; omitting the key when the family was requested is refused with `CONSTRAINT_FENCE_AUDIT_FAMILY_UNSUPPORTED` rather than reported as a clean result. A backend that cannot commit a preflight atomically refuses a tightening with `ONTOLOGY_TIGHTENING_REQUIRES_ATOMIC_BACKEND`, and a preflight target that cannot run the audit refuses with the existing `CONSTRAINT_FENCE_AUDIT_UNSUPPORTED`.

The audit gains an `edgeEndpointAssignability` family reporting non-deleted edges sitting outside every declared endpoint pair, whatever their validity window: a future-dated edge becomes current once the clock reaches it, and an ended one is what an `asOf` read inside its window returns, so a narrowing is probed against both.

The stored side is a delta input no store reads or writes through, so it is excused from the two contracts that postdate documents already stored — structural subsumption, and the `partOf`/`hasPart` declaration rules (a relation with no `via`, or a realizing edge those rules refuse) — which is what lets a fix-forward commit that corrects or removes the offending relation be classified at all. Any other stored-side incoherence (a subclass cycle, an invalid equivalence class) still refuses. Every read-only caller built on `computeSchemaDiff` inherits this: `loadAndVerifyGraph` (and so `createVerifiedStore` / `assertSchemaCurrent`) and `getSchemaChanges()` now also throw `ConfigurationError` for the same documents. `requiresMigration()` is the one exception: it treats "cannot classify" the same as "needs migration" and returns `true` instead of throwing, so a document only the privileged path can interpret still routes there. @@ -28,6 +28,10 @@ - Removing a `partOf`/`hasPart` pair, and adding or removing `inverseOf`/`implies`, now requires an explicit `migrateSchema()` even against clean data: `ensureSchema()`'s auto-migrate branch refuses these with `MigrationError` `reason: "breaking-change"`. - A `subClassOf`/`equivalentTo`/`disjointWith`/`partOf`/`hasPart` addition the data already violates is refused with `MigrationError` `reason: "ontology-tightening-violated"`.

scope provenance part closes to support changes The store.search() facade now asks the schema introspector (the owner the query builder already uses) which expanded kinds an index would miss, and refuses them with SEARCH_EXPANSION_KIND_UNINDEXED instead of silently under-returning: a fulltext expansion where a subclass redeclares a searchable field untagged, and a vector expansion where a subclass redeclares the embedding field untagged. The introspector is built once per registry and shared by the builder and the facade. A stated includeSubClasses is refused with QUERY_ALIAS_EXPANSION_INVALID naming expansion on from/to/fromDynamic/toDynamic and every search leg, rather than read as no option. Recorded-time StoreView getById/getByIds/scan (node and edge) refuse a stated coordinate through assertNoStatedCoordinate, like the valid-time views. A provenance transition carries a fact whole's required parts into scope only when the whole's support differs between the before and after snapshots, so retracting one of several supports no longer closes an unjustified part of a surviving whole. Changesets and docs: alias types widen whatever the store default, typed edge collections keep declared endpoint kinds (documented limitation), Breaking bullets for the removed engine-author members, IdentityReplayError in the identity changeset, internal codes removed from test names. --- .changeset/edge-kind-integrity.md | 1 + .changeset/identity-reconciliation.md | 2 + .changeset/identity-write-path-consistency.md | 1 + .changeset/typed-subsumption.md | 13 +- apps/docs/src/content/docs/fulltext-search.md | 9 + apps/docs/src/content/docs/ontology.md | 11 + apps/docs/src/content/docs/queries/source.md | 5 +- apps/docs/src/content/docs/schemas-stores.md | 4 +- apps/docs/src/content/docs/semantic-search.md | 6 +- .../typegraph/etc/api-surface-exceptions.json | 64 +++++ ...pters-drizzle-postgres-working-copy.api.md | 1 + .../etc/typegraph-graph-merge.api.md | 1 + .../etc/typegraph-interchange.api.md | 1 + .../etc/typegraph-postgres-pglite.api.md | 1 + .../typegraph/etc/typegraph-profiler.api.md | 1 + .../typegraph/etc/typegraph-provenance.api.md | 1 + .../etc/typegraph-sqlite-local.api.md | 1 + packages/typegraph/etc/typegraph.api.md | 1 + packages/typegraph/src/provenance/index.ts | 26 +- packages/typegraph/src/query/builder.ts | 8 +- .../src/query/builder/alias-expansion.ts | 43 +++- .../src/query/schema-introspector.ts | 54 +++++ packages/typegraph/src/store/search.ts | 129 ++++++++-- packages/typegraph/src/store/store-view.ts | 36 ++- .../backends/integration/composition-fence.ts | 8 +- .../integration/ontology-typed-subsumption.ts | 228 ++++++++++++++++++ .../tests/provenance-composition.test.ts | 64 +++++ .../store-view-sealed-coordinate.test.ts | 64 +++++ .../tests/structural-subtype.test.ts | 2 +- .../tests/typed-subsumption-types.test.ts | 13 + 30 files changed, 740 insertions(+), 59 deletions(-) diff --git a/.changeset/edge-kind-integrity.md b/.changeset/edge-kind-integrity.md index e4774ba7e..df0694177 100644 --- a/.changeset/edge-kind-integrity.md +++ b/.changeset/edge-kind-integrity.md @@ -24,6 +24,7 @@ Schema serialization, hashing, introspection, runtime graph extensions and schem - `GraphBackend.lockSchemaVersionAndGraphWrite` resolves the new `GraphWriteFenceAcquisition` (`{ isolation, fenceRow: "advanced" | "none" }`) instead of a bare `GraphCommandIsolation`.

Archival interchange carries a `transitions` section plus the retention watermark, bumping the interchange format to `3.0`; older documents still import and validate unchanged. Restoring an archive's transitions validates shape only and never re-derives membership, every restored row is marked as such so `replay` never pairs it with a fabricated before/after, and when the destination had no identity transitions of its own before the import began the restore also sets its own watermark, so `replay` reports the pre-restore range honestly instead of claiming a complete history it cannot reconstruct. That decision and the watermark's value are read once, ahead of the import's first write (for a stream, at its header, before the first chunk commits), so `importGraph` and `importGraphStream` restore one archive to the same watermark, and the transitions a streamed restore's own node and assertion chunks record never count as the destination's earlier history.

A candidate kind with no subclasses or equivalents is unaffected. - **A saved pagination cursor from a supertype query no longer matches that query.** A query whose source now resolves to several kinds orders by an added `kind` tiebreaker before `id`, so a cursor encoded before the upgrade is refused with `ValidationError` (cursor column mismatch).

A value outside the accepted set is refused with `QUERY_ALIAS_EXPANSION_INVALID`, and so is a stated `includeSubClasses` from untyped code, on every one of those entry points and on `store.search()` (the message names `expansion`): the option is never read as "no option", so a JavaScript `{ includeSubClasses: false }` cannot silently become the polymorphic default. +- **The internal `SchemaIntrospector` replaces `hasSearchableField` with `kindsWithoutSearchableField`**, which answers the same question and names the kinds that leave an alias without searchable content, and gains `kindsRedeclaringEmbeddingUntagged`. The introspector is built by the library for the query builder and the search facade and is not exported from any entrypoint, so only code that reaches into a builder's internals is affected. - **`QueryAst`'s `start.includeSubClasses: boolean` becomes `start.expansion: "exact" | "subclasses" | "narrower"`.** This affects only code inspecting a compiled AST directly. -- **Alias types widen under the polymorphic axis.** For a kind that some other kind declares itself a subclass of, or that participates in a registered-kind `equivalentTo`, the alias's `kind` is `string` and its `NodeId` brand widens.

A relation endpoint declared as a UNION of kinds, spelled `typeof Audio | typeof Video` or `NodeType<"Audio" | "Video">`, widens every kind the union can hold. A graph declaring no subsumption relations is unaffected. Alias types widen whatever the store default: `queryDefaults: { expansion: "exact" }` changes the rows an alias returns, not its type, so an affected kind still types `kind` as `string` and its id is not accepted by the kind's own collection. State `{ expansion: "exact" }` on the call (`from("Person", "p", { expansion: "exact" })`) to keep the literal alias type. - **Expanded search hits widen the same way.** `store.search.fulltext` / `vector` / `hybrid` called with `expansion: "subclasses"` on such a kind no longer claims the exact searched kind: `hit.node.kind` is `string` and `hit.node.id` is no longer accepted by the searched kind's own collection methods. Narrow on `hit.node.kind` first, or search with the default `"exact"` axis. A search that states no `expansion`, and a kind no subsumption relation names, are unaffected. - **Annotating a relation as `OntologyRelation` widens every alias in that graph.** Such code still compiles, but its aliases' `kind` and `NodeId` types widen to the polymorphic form — let the factory's return type be inferred to keep the narrow types. - **An equivalence class mixing node and edge kinds, or holding two registered edge kinds, is refused** with `ConfigurationError` `ONTOLOGY_EQUIVALENCE_INVALID_CLASS` where it previously loaded inert; a persisted schema carrying one fails on load, so correct the stored document before upgrading. `equivalentTo`'s first parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI. diff --git a/apps/docs/src/content/docs/fulltext-search.md b/apps/docs/src/content/docs/fulltext-search.md index fe642a215..3269a39c1 100644 --- a/apps/docs/src/content/docs/fulltext-search.md +++ b/apps/docs/src/content/docs/fulltext-search.md @@ -493,6 +493,15 @@ applies (search across multiple kinds must agree on one declared metric; see this asymmetry surprises you, that's the intended signal that it's worth double-checking whether your search call should opt in explicitly. +An expansion that would silently miss rows is refused rather than +under-returned, exactly where `$fulltext.matches()` refuses the same alias: if +a subclass redeclares a `searchable()` field without `searchable()`, its text +is not in the index, so `expansion: "subclasses"` throws `ConfigurationError` +(`SEARCH_EXPANSION_KIND_UNINDEXED`) naming the kind.

A role that performs those writes needs `INSERT` and `UPDATE` on that table. Every other holder of the fence — a history-capturing or revision-tracking write, a cardinality, uniqueness or disjointness write, a provenance `holding()` read — takes the lock alone, writes no row and issues the statements it issued before. The row is updated once per deciding transaction, so while a transaction holding an older snapshot stays open (`pg_dump`, a long report, an idle-in-transaction session) its dead versions accumulate and those deciding writes slow until the snapshot closes and the table is vacuumed; see "Write Fence Row" in the limitations guide. -- A `store.transaction` whose callback holds a raw SQL handle (`tx.sqlAvailability: "available"`) now takes the per-graph write fence at every constraint-fenced write instead of once per transaction. A `ROLLBACK TO SAVEPOINT` issued through `tx.sql` releases an advisory lock taken after that savepoint and undoes a fence-row advance made after it, so a later fenced write in the same transaction previously ran under a lock it no longer held. Transactions without the handle (history capture, revision tracking, or no native transaction) still take the fence once. +- A `store.transaction` whose callback holds a raw SQL handle (`tx.sqlAvailability: "available"`) now takes the per-graph write fence at every constraint-fenced write instead of once per transaction.

Transactions without the handle (history capture, revision tracking, or no native transaction) still take the fence once, and the schema-fence lease follows the same rule. +- `TransactionReadBackend`, the `tx.backend` of every transaction context, no longer has `execute`. Its compiled-query brand is a type only, so `tx.backend.execute` ran any SQL on the transaction's session — including a `ROLLBACK TO SAVEPOINT` that released the per-graph write fence and the schema fence while the transaction's later writes kept relying on them, which let two transactions commit a cycle into an `acyclic` relation, and on a history store writes that bypassed capture. `tx.sql` is now the one raw handle a transaction context carries. Run TypeGraph queries in a transaction with `tx.query()`, and raw SQL through an `AdapterStore` transaction's `tx.sql`, whose transactions take every fence again at each write. - At `REPEATABLE READ` or `SERIALIZABLE`, such a PostgreSQL write now fails with SQLSTATE `40001` on that row when another such writer committed past its snapshot, reported as `TransactionConflictError` with the driver error as `cause`. Retry the whole transaction, as for any serialization failure. -- A PostgreSQL collection write or import that names a constraint, in a transaction TypeGraph opened, and every `bulkUpsertById` and `bulkGetOrCreateByConstraint`, is now replayed up to three times on a serialization failure or deadlock and raises `TransactionConflictError` once the attempts are spent, where the driver error previously propagated from the first failure.

A write that names no constraint takes one attempt, as before. SQLite is unchanged. - `getOrCreateByEndpoints` and `bulkGetOrCreateByEndpoints` now accept a `REPEATABLE READ` create leg on the bundled PostgreSQL backends, where it was refused with `MATCH_KEY_CONVERGENCE_REQUIRES_FRESH_SNAPSHOT`. A custom backend whose fence is an advisory lock with no fences relation (`tableNames.fences`) is now refused at `SERIALIZABLE` as well as `REPEATABLE READ`, with the same code, where `SERIALIZABLE` was previously accepted. - `GraphBackend.lockSchemaVersionAndGraphWrite` resolves the new `GraphWriteFenceAcquisition` (`{ isolation, fenceRow: "advanced" | "none" }`) instead of a bare `GraphCommandIsolation`. Its params gain a required `fenceRow: "advance" | "leave"`: a custom backend implementing it advances the graph's fence row only for `"advance"`, and reports `fenceRow: "advanced"` only when its statement did. `FenceStatements` gains the optional `acquireKeyedSnapshotFence`, which is absent for an advisory fence that names no fences relation; a fence without it cannot advance a fence row, so the deciding writes above are refused on it at `REPEATABLE READ` and `SERIALIZABLE`. - `EdgeRegistration` gains `targetCardinality?`, `EdgeIntrospection` gains a required `targetCardinality` and a required `acyclic` boolean (`false` unless declared), and `SerializedEdgeDef` gains an optional `targetCardinality?`. Code that builds either object literal by hand adds the field; everything produced through `defineGraph`, the serializer or `introspectSchema` is unaffected. The serializer omits `targetCardinality` when it is undeclared or explicitly the default `"many"`, so a graph that never uses the option serializes and hashes byte-identically to a pre-release document and keeps `ensureSchema`'s schema-hash fast path.

Under the advisory schema fence the schema-write transaction now asks for READ COMMITTED, and the fence's advisory-lock statement reads the session's isolation back and refuses anything else with SCHEMA_WRITE_REQUIRES_READ_COMMITTED, which also covers a caller's snapshot-isolated transaction handed to adoptSchemaWriteTransaction. One resolver owns the schema-commit fence plan for both the transaction config and the acquisition. --- .changeset/edge-kind-integrity.md | 1 + apps/docs/src/content/docs/errors.md | 1 + .../docs/src/content/docs/schema-evolution.md | 5 +- .../typegraph/src/backend/command-contract.ts | 4 +- .../typegraph/src/backend/drizzle/postgres.ts | 110 +++++++-- .../engine-profile-parity.test.ts.snap | 12 +- .../postgres/schema-commit-isolation.test.ts | 220 ++++++++++++++++++ 7 files changed, 336 insertions(+), 17 deletions(-) create mode 100644 packages/typegraph/tests/backends/postgres/schema-commit-isolation.test.ts diff --git a/.changeset/edge-kind-integrity.md b/.changeset/edge-kind-integrity.md index 26c06c7ca..6fac2aa2e 100644 --- a/.changeset/edge-kind-integrity.md +++ b/.changeset/edge-kind-integrity.md @@ -19,6 +19,7 @@ Schema serialization, hashing, introspection, runtime graph extensions and schem - On PostgreSQL, a write that makes a decision only the per-graph write fence protects now advances one row per graph in `typegraph_fences` (part of the base schema since the fence-rows release), behind the advisory lock: a write into an `acyclic` or composition relation, a delete of a composition whole, and a match-key convergence (`getOrCreateByEndpoints`, `bulkGetOrCreateByEndpoints` or a coalescing upsert on a match key no database key backs). A role that performs those writes needs `INSERT` and `UPDATE` on that table. Every other holder of the fence — a history-capturing or revision-tracking write, a cardinality, uniqueness or disjointness write, a provenance `holding()` read — takes the lock alone, writes no row and issues the statements it issued before. The row is updated once per deciding transaction, so while a transaction holding an older snapshot stays open (`pg_dump`, a long report, an idle-in-transaction session) its dead versions accumulate and those deciding writes slow until the snapshot closes and the table is vacuumed; see "Write Fence Row" in the limitations guide. - A `store.transaction` whose callback holds a raw SQL handle (`tx.sqlAvailability: "available"`) now takes the per-graph write fence at every constraint-fenced write instead of once per transaction. A `ROLLBACK TO SAVEPOINT` issued through `tx.sql` releases an advisory lock taken after that savepoint and undoes a fence-row advance made after it, so a later fenced write in the same transaction previously ran under a lock it no longer held. Transactions without the handle (history capture, revision tracking, or no native transaction) still take the fence once, and the schema-fence lease follows the same rule. - `TransactionReadBackend`, the `tx.backend` of every transaction context, no longer has `execute`. Its compiled-query brand is a type only, so `tx.backend.execute` ran any SQL on the transaction's session — including a `ROLLBACK TO SAVEPOINT` that released the per-graph write fence and the schema fence while the transaction's later writes kept relying on them, which let two transactions commit a cycle into an `acyclic` relation, and on a history store writes that bypassed capture. `tx.sql` is now the one raw handle a transaction context carries. Run TypeGraph queries in a transaction with `tx.query()`, and raw SQL through an `AdapterStore` transaction's `tx.sql`, whose transactions take every fence again at each write. +- A PostgreSQL schema write — a schema commit, an activation, and the tightening preflight or emptiness probe run before either — now opens its transaction at `READ COMMITTED` whatever the server's `default_transaction_isolation` is, and the advisory schema fence refuses a session that reports any other isolation with `ConfigurationError` code `SCHEMA_WRITE_REQUIRES_READ_COMMITTED` (`details.isolation`). The refusal is reachable through `adoptSchemaWriteTransaction` on a caller's `REPEATABLE READ` or `SERIALIZABLE` transaction. At a snapshot-isolation default the preflight previously read a snapshot taken before the commit waited for the writers holding the schema row, and could activate a tightening such as `acyclic: true` over rows written while it waited. - At `REPEATABLE READ` or `SERIALIZABLE`, such a PostgreSQL write now fails with SQLSTATE `40001` on that row when another such writer committed past its snapshot, reported as `TransactionConflictError` with the driver error as `cause`. Retry the whole transaction, as for any serialization failure. - A PostgreSQL collection write or import that names a constraint, in a transaction TypeGraph opened, and every `bulkUpsertById`, `bulkReplaceById` and `bulkGetOrCreateByConstraint`, is now replayed up to three times on a serialization failure or deadlock and raises `TransactionConflictError` once the attempts are spent, where the driver error previously propagated from the first failure. A write that names no constraint takes one attempt, as before. SQLite is unchanged. - `getOrCreateByEndpoints` and `bulkGetOrCreateByEndpoints` now accept a `REPEATABLE READ` create leg on the bundled PostgreSQL backends, where it was refused with `MATCH_KEY_CONVERGENCE_REQUIRES_FRESH_SNAPSHOT`. A custom backend whose fence is an advisory lock with no fences relation (`tableNames.fences`) is now refused at `SERIALIZABLE` as well as `REPEATABLE READ`, with the same code, where `SERIALIZABLE` was previously accepted. diff --git a/apps/docs/src/content/docs/errors.md b/apps/docs/src/content/docs/errors.md index 2ebb1157a..77bd342cd 100644 --- a/apps/docs/src/content/docs/errors.md +++ b/apps/docs/src/content/docs/errors.md @@ -1655,6 +1655,7 @@ data check atomically: | `UNIQUE_CONSTRAINT_CHANGE_REQUIRES_ATOMIC_BACKEND` | The backend cannot verify that a kind is empty atomically with the schema-version compare-and-swap.

A retraction and a reassertion of one identity pair are convergent only when every branch that retracts the pair also reasserts it; a branch that only retracts while another retracts and reasserts is refused as a retract/reassert race instead of being silently overruled. Merge apply passes the plan's edge deletions to its node deletes as consumed edges, so a branch that deletes an edge and then its restrict endpoint merges. A plan that deletes a part the target has moved under another live whole is reported on the plan (cause "moved") and refused at apply with MergeCompositionOrphanError, whose code becomes GRAPH_MERGE_COMPOSITION_ORPHAN. Unknown keys inside resolve configs, resolve entries for undeclared node kinds and unknown apply options are refused with InvalidMergeOptionsError. Apply records a review digest only from a compatible review revalidation that names the applied plan, and applyMergePlanInTransaction accepts the same decision provenance. --- .changeset/composition.md | 2 +- .changeset/identity-reconciliation.md | 11 +- .../merge-apply-consumed-edge-deletes.md | 5 + apps/docs/src/content/docs/errors.md | 26 +-- apps/docs/src/content/docs/graph-merge.md | 30 +++- apps/docs/src/content/docs/identity.md | 7 +- .../etc/typegraph-graph-merge.api.md | 23 ++- .../examples/27-durable-merge-review.ts | 6 +- .../src/graph-merge/apply-callbacks.ts | 141 ++++++++++++--- packages/typegraph/src/graph-merge/errors.ts | 38 ++-- .../src/graph-merge/identity-decision.ts | 24 ++- .../src/graph-merge/identity-separation.ts | 112 ++++++++---- .../src/graph-merge/identity-three-way.ts | 47 +++-- packages/typegraph/src/graph-merge/index.ts | 2 + packages/typegraph/src/graph-merge/merge.ts | 136 ++++++++++++--- packages/typegraph/src/graph-merge/options.ts | 140 +++++++++++++-- .../typegraph/src/graph-merge/plan-schema.ts | 18 +- .../src/graph-merge/typegraph-internal.ts | 2 + .../integration/graph-merge-review.ts | 4 +- .../graph-merge/composition-orphan.test.ts | 129 ++++++++++++-- .../identity-decision-provenance.test.ts | 163 +++++++++++++++++- .../tests/graph-merge/identity-merge.test.ts | 105 +++++++++-- .../identity-reconciliation.test.ts | 6 +- ...dentity-separation-storage-missing.test.ts | 3 + .../identity-separation-veto.test.ts | 88 ++++++++++ .../graph-merge/identity-three-way.test.ts | 24 +++ .../node-delete-policy-wiring.test.ts | 61 ++++++- .../graph-merge/undeclared-options.test.ts | 98 +++++++++++ 28 files changed, 1266 insertions(+), 185 deletions(-) create mode 100644 .changeset/merge-apply-consumed-edge-deletes.md diff --git a/.changeset/composition.md b/.changeset/composition.md index 122644af0..42a5e02cf 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -28,7 +28,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all.

A `beforeRecorded` beyond every revision the graph holds (its next commit's revision, or one past the highest retained transition when an archival restore carried higher revisions in) is refused with `IDENTITY_PRUNE_BEYOND_RECORDED_CLOCK`, since it would claim history the graph has yet to record as already pruned; the retention watermark itself never rises above the next commit's revision, and restored rows are pruned by their raw revision number alongside native rows. Archival interchange carries a `transitions` section plus the retention watermark, bumping the interchange format to `3.0`; older documents still import and validate unchanged. Restoring an archive's transitions validates shape only and never re-derives membership, every restored row is marked as such so `replay` never pairs it with a fabricated before/after, and when the destination had no identity transitions of its own before the import began the restore also sets its own watermark, so `replay` reports the pre-restore range honestly instead of claiming a complete history it cannot reconstruct. That decision and the watermark's value are read once, ahead of the import's first write (for a stream, at its header, before the first chunk commits), so `importGraph` and `importGraphStream` restore one archive to the same watermark, and the transitions a streamed restore's own node and assertion chunks record never count as the destination's earlier history. A streamed document whose header does not announce identity transitions (`identity.hasTransitions`) but whose chunks carry them is refused, since an unannounced transition has no restore floor and would silently drop the watermark.

One narrow, deliberate behavior change ships in how a merge ends an assertion: when two branches end the same base identity assertion at different valid-time instants, the merge commits the earliest staged `validTo` rather than whichever branch happened to be staged last. The rule is deterministic and branch-order-independent, but it is a real change to which instant a merge commits. The same rule holds when one branch's deletion cascades an ending onto an assertion and another branch retracts it explicitly: if the delete/modify resolution overrules the deletion, the surviving retraction commits at the instant and with the cause of the contributions that still stand, not those of the overruled cascade. @@ -22,11 +22,12 @@ A durable merge plan built under `reconcileTypes: "ontology"` also no longer fai A transaction receipt's `writes.identity` gains `transitions`, counted beside and never inside `total`: the number of identity transition-log notes the transaction's flush wrote. -`applyMergePlanInTransaction()` records the same identity decision as `applyMergePlan()` for one plan. `applyDurableMergePlan()` always applies through the target Store transaction, so the plan's identity and composition work runs through TypeGraph's own write path; a strategy that still declares a native `merge()` is refused. +`applyMergePlanInTransaction()` records the same identity decision as `applyMergePlan()` for one plan, and accepts the same `review` and `sourceId` provenance as an optional fourth argument (`MergePlanDecisionOptions`). `applyDurableMergePlan()` always applies through the target Store transaction, so the plan's identity and composition work runs through TypeGraph's own write path; a strategy that still declares a native `merge()` is refused. ### Breaking -- A merge option `MergeOptions` does not declare is refused with `InvalidMergeOptionsError` (`details.option` names the key) by every merge and plan entry point (`merge()`, `mergeIncremental()`, `planMerge()`, `planMergeIncremental()`, …) and by candidate write-set review, where it was previously ignored.

The refusal reaches inside `resolve`: an entry for a node kind the graph does not declare (`details.option` `"resolve."`), an undeclared key in a kind's resolve config, its `keyless` bag, its similarity strategy or a hybrid strategy's `weights` (`"resolve..similarity."`, …), and an unknown similarity `kind` are refused the same way. `applyMergePlan()` and `applyDurableMergePlan()` likewise refuse an apply option `MergePlanApplyOptions` does not declare. Remove the key, or correct its spelling. +- A merge where one branch retracts an inherited identity assertion while another branch retracts it and asserts the same pair again under a new id now fails with `IdentityMergeConflictError` ("retract/reassert race"), where it previously merged and silently kept the re-assertion. A retraction and a re-assertion of one pair merge only when every branch that retracts the pair also re-asserts it. Reconcile the branches — either every retracting branch re-asserts the pair or none does — then merge again. - A candidate match between two entities whose identity classes a `different` assertion holds apart no longer reaches the commit. A scored match is dropped and reported on `MergeReport.identityConflicts`, and the merge succeeds where it previously failed in the commit; a definitional match or a transitive cluster fails at plan time with `GRAPH_MERGE_IDENTITY_SEPARATION_CONFLICT` rather than the commit's generic refusal. `IdentityMergeConflictError.code` is typed `IdentityMergeConflictCode`, the union of that code and `GRAPH_MERGE_IDENTITY_CONFLICT`. - `MergeReport` gains the required member `identityConflicts`, and `CandidateDiagnostic`'s `clusterDisposition.reason` gains `"separation"`. Code that constructs a `MergeReport`, or switches exhaustively over the exclusion reason, must account for both. - `EntityResolution.kind` (on `MergeReport.resolutions` and a plan artifact's `review.resolutions`) names the reconciled kind for a cluster the ontology cascade retypes. Code that joined a resolution to its staged members by the survivor's pre-retype kind should read `TypeReconciliation.fromTypes` for the staged kinds; clusters no retype touches are unchanged. diff --git a/.changeset/merge-apply-consumed-edge-deletes.md b/.changeset/merge-apply-consumed-edge-deletes.md new file mode 100644 index 000000000..17e3e41f6 --- /dev/null +++ b/.changeset/merge-apply-consumed-edge-deletes.md @@ -0,0 +1,5 @@ +--- +"@nicia-ai/typegraph": patch +--- + +A graph merge no longer refuses a branch that deletes an edge and then the edge's `restrict` endpoint, the order `onDelete: "restrict"` (the default) forces on the branch itself.

From 46ebf01aa9f5b13c5c5364b12e9623c564b95d0e Mon Sep 17 00:00:00 2001 From: Paul Dlug Date: Wed, 21 Oct 2026 15:50:22 -0700 Subject: [PATCH 207/255] Scope identity history to membership, harden archival transition restore, and adopt base schema 6 on durable reopen transitionsOf and replay now report a transition only while the reference was a member of the class it names, judged against the class reconstructed just before and at each boundary; the same reconstruction supplies replay's before/after. A class the reference has left no longer contributes its later merges as phantom steps. Page cursors are bound to the reference they page, and a restored transition's recorded instant is typed RestoredRecordedInstant so asOfRecorded refuses it. The exhaustiveness property now opens half its runs with the seed joining and leaving a class, and no longer exempts revisions the seed sat out. Archival restore takes one decision on whether an import restores transitions (a zero watermark does not), shared by the up-front refusal, the baseline read and the restore. Ordering and state-mode shape checks run before the first write; a state-mode retention watermark is refused; a stream holds transitions to one order across chunks and is refused when its header announced a restore that never arrived. A purged required part whose identity detach fails now fails the import instead of being reported as kept, and a purged part's message names the purge rather than a missing partOf. A durable PostgreSQL working copy adopts missing base-schema steps in place on reopen and refuses a newer marker. A capture flush that reaches a missing transition-log relation names those relations and points to base-schema adoption. Base-schema version 6 is documented in the backend setup and authoring guides, and the changeset carries the upgrade note. --- .changeset/identity-reconciliation.md | 10 +- .../src/content/docs/backend-authoring.md | 25 + apps/docs/src/content/docs/backend-setup.md | 64 +++ apps/docs/src/content/docs/errors.md | 21 +- apps/docs/src/content/docs/graph-merge.md | 7 +- apps/docs/src/content/docs/identity.md | 54 +- apps/docs/src/content/docs/interchange.md | 15 +- ...pters-drizzle-postgres-working-copy.api.md | 44 +- packages/typegraph/etc/typegraph-core.api.md | 5 + .../etc/typegraph-graph-merge.api.md | 44 +- .../etc/typegraph-interchange.api.md | 44 +- .../etc/typegraph-postgres-pglite.api.md | 44 +- .../typegraph/etc/typegraph-profiler.api.md | 44 +- .../typegraph/etc/typegraph-provenance.api.md | 44 +- .../etc/typegraph-sqlite-local.api.md | 44 +- packages/typegraph/etc/typegraph.api.md | 47 +- .../typegraph/examples/29-identity-history.ts | 4 +- packages/typegraph/scripts/api-report.ts | 35 +- .../backend/drizzle/postgres-working-copy.ts | 44 +- packages/typegraph/src/core/index.ts | 1 + packages/typegraph/src/core/temporal.ts | 13 + packages/typegraph/src/identity/index.ts | 3 +- packages/typegraph/src/identity/replay.ts | 470 ++++++++++++------ .../src/identity/service-interchange-write.ts | 84 +++- packages/typegraph/src/identity/service.ts | 2 + packages/typegraph/src/identity/types.ts | 15 +- packages/typegraph/src/index.ts | 4 +- packages/typegraph/src/interchange/import.ts | 216 +++++--- .../src/store/recorded-capture/flush.ts | 20 +- packages/typegraph/src/store/store.ts | 5 +- packages/typegraph/src/utils/sql-errors.ts | 49 +- .../backends/integration/identity-replay.ts | 77 ++- .../pglite-identity-transition-log.test.ts | 9 +- ...es-working-copy-base-schema-reopen.test.ts | 188 +++++++ .../tests/identity-import-hardening.test.ts | 280 +++++++++++ .../typegraph/tests/identity-replay.test.ts | 75 ++- ...entity-transition-log-provisioning.test.ts | 45 +- .../composition-existence-import.test.ts | 79 ++- .../identity-replay-exhaustive.test.ts | 66 +-- 39 files changed, 1862 insertions(+), 478 deletions(-) create mode 100644 packages/typegraph/tests/backends/postgres/postgres-working-copy-base-schema-reopen.test.ts diff --git a/.changeset/identity-reconciliation.md b/.changeset/identity-reconciliation.md index 43302e6ce..84a1589b0 100644 --- a/.changeset/identity-reconciliation.md +++ b/.changeset/identity-reconciliation.md @@ -2,13 +2,13 @@ "@nicia-ai/typegraph": minor --- -**Replayable identity history.** An identity-enabled graph with history capture now retains a replayable identity history: `store.identity.transitionsOf(ref)` returns every transition that changed a node's identity class — assertions, retractions, same-id folds, deletes and restores, validity-window ends, kind drops, schema transitions and the identity changes a graph merge applies — each carrying the ids of the `same` assertions that touched its own class (a bulk write names on each transition only the assertions with an endpoint in that class, never the whole batch), both temporal coordinates, and, for a change a merge applied, the branch, branch ancestry and plan and review digests that produced it.

A whole reached while already unsupported is closed, and its required parts used to stay live under the tombstone; a supported but tombstoned whole that is reopened used to leave its tombstoned parts behind. store.search fulltext (and the fulltext leg of hybrid) now asks the schema introspector about every resolved kind list, an exact search included, so a kind with no searchable() field or an untagged redeclaration is refused with SEARCH_EXPANSION_KIND_UNINDEXED where the query builder refuses the same alias, instead of returning nothing. The vector facade no longer has its own embedding-tag predicate. The introspector's subsuming-declaration decision (the one the shared-field accessor makes before trusting a subsuming kind) is extracted once and both the builder and the facade ask it, which also names the right kind when a subclass tags a field its parent declares plain. A null options argument from untyped code is no longer read as a property access in the removed-option check. The recorded view refusals are listed in the changeset, a misnamed test is renamed and two doc comments are re-wrapped. --- .changeset/store-view-sealed-reads.md | 2 +- .changeset/typed-subsumption.md | 2 +- apps/docs/src/content/docs/fulltext-search.md | 7 +- apps/docs/src/content/docs/semantic-search.md | 7 +- .../typegraph/etc/api-surface-exceptions.json | 32 ++-- ...pters-drizzle-postgres-working-copy.api.md | 2 +- .../etc/typegraph-graph-merge.api.md | 2 +- .../etc/typegraph-interchange.api.md | 2 +- .../etc/typegraph-postgres-pglite.api.md | 2 +- .../typegraph/etc/typegraph-profiler.api.md | 2 +- .../typegraph/etc/typegraph-provenance.api.md | 2 +- .../etc/typegraph-sqlite-local.api.md | 2 +- packages/typegraph/etc/typegraph.api.md | 2 +- packages/typegraph/src/provenance/index.ts | 41 +++-- .../src/query/builder/alias-expansion.ts | 4 +- .../src/query/schema-introspector.ts | 98 ++++++----- packages/typegraph/src/store/search.ts | 68 ++++---- .../integration/ontology-typed-subsumption.ts | 152 +++++++++++++++++- .../tests/provenance-composition.test.ts | 119 ++++++++++++++ .../tests/schema-introspector.test.ts | 88 ++++++++++ 20 files changed, 520 insertions(+), 116 deletions(-) diff --git a/.changeset/store-view-sealed-reads.md b/.changeset/store-view-sealed-reads.md index c999be622..95e225803 100644 --- a/.changeset/store-view-sealed-reads.md +++ b/.changeset/store-view-sealed-reads.md @@ -2,7 +2,7 @@ "@nicia-ai/typegraph": patch --- -**A `StoreView` read refuses a temporal coordinate its caller states instead of silently answering at the pin.** `view.subgraph()`, the ten algorithm reads (on the view and on `view.algorithms`), `view.bulkFindEdgesFrom()` / `bulkFindEdgesTo()`, `view.edges..bulkFindFrom()` / `bulkFindTo()` and the point reads (`getById`, `getByIds`, `find`, `count`, and on edges `findFrom`, `findTo`, `findByEndpoints`) omit `temporalMode`, `asOf` and `recordedAsOf` from their option types, but an untyped caller could still pass them, in the position the live collection takes its own temporal options; the view answered at the pin and dropped the stated value.

The flip side: a relation annotated as the bare `OntologyRelation` widens every alias in that graph conservatively. An endpoint declared as a union of node types keeps its literals and stays precise, widening exactly the kinds the union can hold and nothing else. Known limitation: typed edge collections (`store.edges.`) still type an edge's endpoint by the declared kinds, not by the subclass or equivalent kinds the edge admits at runtime, so `edge.toKind` may be `"Employee"` where it is typed `"Person"`; narrow on the runtime kind before choosing a collection. diff --git a/apps/docs/src/content/docs/fulltext-search.md b/apps/docs/src/content/docs/fulltext-search.md index 3269a39c1..c9a3793cf 100644 --- a/apps/docs/src/content/docs/fulltext-search.md +++ b/apps/docs/src/content/docs/fulltext-search.md @@ -497,8 +497,11 @@ An expansion that would silently miss rows is refused rather than under-returned, exactly where `$fulltext.matches()` refuses the same alias: if a subclass redeclares a `searchable()` field without `searchable()`, its text is not in the index, so `expansion: "subclasses"` throws `ConfigurationError` -(`SEARCH_EXPANSION_KIND_UNINDEXED`) naming the kind.

That stored hash no longer matches the hash this release computes for the same graph, so every comparison of a stored schema version against a graph, or against another stored version, now hashes the stored document in this release's serialization instead of reading the `schema_hash` column: the dropped meta-edge fields are ignored and the precomputed closures are recomputed from the stored relations. Boot (`ensureSchema`, `createVerifiedStore`), `registerGraphTemplate`, `refreshSchema`, `planEvolution`, `branch()`, graph merge plans and candidate reviews, and the provenance sidecar ownership check therefore all treat such a document as current.

Code that matched on `entity === "metaEdge"` no longer has a case to match. `"relation"` is the relation-level severity table. `"edgeRegistration"` classifies an edge kind's `acyclic` flag turning on or off, and an edge kind's `from`/`to` declaration narrowing so it no longer admits endpoint pairs it did — those are edge-registration properties, not ontology relations, and a switch written from the old `"relation"`-only note does not compile. diff --git a/.changeset/typed-subsumption.md b/.changeset/typed-subsumption.md index 4cfe3db55..666bb9fd3 100644 --- a/.changeset/typed-subsumption.md +++ b/.changeset/typed-subsumption.md @@ -26,5 +26,5 @@ - **An equivalence class mixing node and edge kinds, or holding two registered edge kinds, is refused** with `ConfigurationError` `ONTOLOGY_EQUIVALENCE_INVALID_CLASS` where it previously loaded inert; a persisted schema carrying one fails on load, so correct the stored document before upgrading. `equivalentTo`'s first parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI. - **Edge endpoints, `implies` and `inverseOf` endpoint validation, and `importGraph`'s endpoint check all accept equivalent kinds.** Some declarations previously refused at registry build now construct. - **A `kindWithSubClasses` uniqueness constraint spans the equivalence class**, so a value that was unique per kind before can now collide.

The serializer writes that, so a redundant side serializes, hashes and diffs like an omitted one, while a side that decides a same-kind composition is kept. The serialized-edge facts builder moves to registry/edge-kind-facts.ts so the serializer can read it without an import cycle. --- packages/typegraph/src/registry/builders.ts | 2 +- .../src/registry/composition-relation.ts | 32 ++++++ .../typegraph/src/registry/edge-kind-facts.ts | 45 ++++++++ packages/typegraph/src/schema/deserializer.ts | 48 +------- .../typegraph/src/schema/ontology-change.ts | 6 +- packages/typegraph/src/schema/serializer.ts | 52 ++++++++- .../schema-composition-part-side.test.ts | 104 ++++++++++++++++++ 7 files changed, 232 insertions(+), 57 deletions(-) create mode 100644 packages/typegraph/tests/schema-composition-part-side.test.ts diff --git a/packages/typegraph/src/registry/builders.ts b/packages/typegraph/src/registry/builders.ts index 60d4ecb38..aa60526ab 100644 --- a/packages/typegraph/src/registry/builders.ts +++ b/packages/typegraph/src/registry/builders.ts @@ -94,7 +94,7 @@ export function buildKindRegistry(graph: G): KindRegistry { * can't resolve to an inherited member instead of `undefined`. * * The serialized-schema sibling of this adapter is - * `buildSerializedEdgeKindFacts` (`src/schema/deserializer.ts`): the two + * `buildSerializedEdgeKindFacts` (`./edge-kind-facts.ts`): the two * read genuinely different representations (a live `GraphDef` vs a persisted * document), so they stay separate, but both feed the one * `expandEdgeEndpointAllowance`. diff --git a/packages/typegraph/src/registry/composition-relation.ts b/packages/typegraph/src/registry/composition-relation.ts index e64a9f2fd..5b341f674 100644 --- a/packages/typegraph/src/registry/composition-relation.ts +++ b/packages/typegraph/src/registry/composition-relation.ts @@ -250,6 +250,38 @@ export function inferCompositionPartSide( return { partSide: inferred }; } +/** + * THE `partSide` a composition relation is persisted and identified by: the + * declared side only when the realizing edge admits the pair in BOTH + * orientations, so the declaration is what decides it; `undefined` when the + * edge's endpoints decide the side, so a redundant `partSide` and an omitted + * one serialize, hash and diff identically.

The create batch takes paired node updates as well.

On `store.nodes.` its `kind` is limited at compile time to the whole kinds the ontology declares for that part kind through `partOf` / `hasPart` (the new `CompositionWholeKinds`); when the ontology also declares a subclass or equivalence relation, or has lost its tuple type, any node kind of the graph is accepted and the runtime check decides. Any other top-level key on the attachment refuses with `ValidationError` (issue path `partOf.`) rather than being dropped. The window is validated once for every surface (canonical bounds, ordered pair), and on a `population: "oneActive"` pair, where only an open-ended edge is a membership, a stated `validTo` refuses with `ValidationError` (code `COMPOSITION_ATTACHMENT_WINDOW_BOUNDED`) instead of writing an edge that attaches nothing. The write is atomic: a dead or missing whole, an undeclared pair, a cardinality or acyclicity refusal, or a lost composition claim aborts the node create too, leaving no orphan row. Every one of those refusals is reached before the node row is written — for `bulkCreate` before any row of the batch, including a cycle or a whole-side cardinality the batch's own items would close together — so a caller that catches one inside an enclosing `store.transaction(...)` keeps nothing of the refused create. An undeclared pair refuses with `ConfigurationError` (`COMPOSITION_WHOLE_NOT_DECLARED`). `via` names the realizing edge kind and is required only when the part kind declares more than one composition pair toward that whole kind: omitting it there refuses with `COMPOSITION_VIA_AMBIGUOUS`, and naming an edge kind that realizes no declared pair between the two refuses with `COMPOSITION_VIA_NOT_DECLARED`. `props` are the realizing edge's own properties, validated against that edge kind's schema exactly as `store.edges..create(...)` would, so a realizing edge with required schema fields is now attachable from a node create at all. A required-existence kind created with no `partOf` refuses with `CompositionExistenceError` (`COMPOSITION_WHOLE_REQUIRED`, `situation: "create"`) before any row is written, and so does restoring a soft-deleted one through an entry that takes no `partOf` (`upsertById`, `bulkUpsertById`, `bulkReplaceById`) unless it still holds a live whole; `partOf` is honored on an optional-existence pair too. A required-existence kind, or any input carrying `partOf`, always takes the portable, fully-validated write path. -**`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`).

Three refusals stay with the write: a new row's own non-attachment refusal (a second unique key it loses, a disjoint kind holding its id), because the unmatched items are created after the matched ones and a matched update may hand them a key; an identity fold that depends on another row the same batch restores; and a concurrent writer the fence does not exclude. A batch with more than one item that owes a write, or one such item next to a new row that states an attachment, pays one extra fenced read pass for this. Bulk writes that do not state a composition attachment keep the established rule: a call that owns its transaction rolls back entirely, while a refusal caught inside an enclosing `store.transaction(...)` can keep the batch's earlier rows, because the operations layer has no savepoints. That includes writing a realizing edge directly: `edges..bulkCreate` and `bulkInsert` decide every item before writing, but `bulkUpsertById` and `bulkGetOrCreateByEndpoints` are ordinary edge batches.

An already-satisfied call with no update to make stays read-only and takes no write fence. **A second whole is refused identically on every write path.** `CompositionError` with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`. A backend without claim relations therefore still holds "one whole per part" across two different realizing edge kinds, under the per-graph lock. diff --git a/apps/docs/src/content/docs/data-sync.md b/apps/docs/src/content/docs/data-sync.md index 22ec81c10..33e2096a6 100644 --- a/apps/docs/src/content/docs/data-sync.md +++ b/apps/docs/src/content/docs/data-sync.md @@ -49,8 +49,10 @@ await store.nodes.Document.bulkDelete(ids); Called on the store, a bulk method owns its transaction: a refused item rolls the whole call back.

The cursor is a position within the windowed lineage, so it composes with `fromRecorded`/`toRecorded` by intersection, and `fromRecorded`/`toRecorded` refuse a page cursor with a `ValidationError`. A cursor is bound to the reference whose lineage it pages; one passed to a read of another reference is refused with a `ValidationError`. Bounding the answer with `fromRecorded`/`toRecorded` never bounds the lineage search, so a window can never hide the note that names an earlier class canonical. `store.identity.replay(ref)` pairs each transition with the class membership before and after it, reconstructed through the same historical reader, at the same coordinate, as `store.asOfRecorded`: a step's `after` is what `store.asOfRecorded(step.transition.recorded).identity.membersOf(ref)` answers, and its `before` is the same read one revision earlier. Both are read under the graph's current schema, so a step recorded before a `sameIdAcrossKinds` flip or a kind removal shows that revision as the current schema reads it, and a validity window still open when a step was recorded stays open in that step however late the replay is asked for. Replay requires `history: true` and refuses with `IDENTITY_REPLAY_REQUIRES_HISTORY` otherwise, or with `IDENTITY_REPLAY_ENGINE_NATIVE_UNSUPPORTED` on a backend that owns recorded time itself, where TypeGraph captures no history to replay; Cloudflare D1 and neon-http continue to refuse identity-enabled graphs outright. -A lineage is discovered from the reference itself as well as from its current class, through the recorded `same` assertions and same-id nodes that ever tied it to one, so the history of a member that has since been deleted or split away is still returned from that member. Only the transitions recorded while the reference was a member of the class they name are returned: a class the reference has left keeps a history of its own, and its later merges and splits are not reported as the reference's.

Only the transitions recorded while the reference was a member of the class they name are returned: a class the reference has left keeps a history of its own, and its later merges and splits are not reported as the reference's. Membership is judged over the kinds the log names and, once a schema transition was recorded, under both same-id settings, so a later kind drop or `sameIdAcrossKinds` change does not remove the history that put the reference in the class. When a graph holds archivally restored transitions that discovery can neither tie to the reference nor rule out, `transitionsOf` and `replay` report the count as `incompleteDiscovery.unattributedRestoredTransitions` rather than returning a short page that looks complete. `pruneIdentityTransitions(store, { beforeRecorded })` trims retained explanations and records a watermark that replay reports rather than hiding. A `beforeRecorded` beyond every revision the graph holds (its next commit's revision, or one past the highest retained transition when an archival restore carried higher revisions in) is refused with `IDENTITY_PRUNE_BEYOND_RECORDED_CLOCK`, since it would claim history the graph has yet to record as already pruned; the retention watermark itself never rises above the next commit's revision, and restored rows are pruned by their raw revision number alongside native rows. Archival interchange carries a `transitions` section plus the retention watermark, bumping the interchange format to `3.0`; older documents still import and validate unchanged. Restoring an archive's transitions validates shape only and never re-derives membership, every restored row is marked as such so `replay` never pairs it with a fabricated before/after, and when the destination had no identity transitions of its own before the import began the restore also sets its own watermark, so `replay` reports the pre-restore range honestly instead of claiming a complete history it cannot reconstruct. That decision and the watermark's value are read once, ahead of the import's first write (for a stream, at its header, before the first chunk commits), so `importGraph` and `importGraphStream` restore one archive to the same watermark, and the transitions a streamed restore's own node and assertion chunks record never count as the destination's earlier history. A streamed document whose header does not announce identity transitions (`identity.hasTransitions`) but whose chunks carry them is refused, since an unannounced transition has no restore floor and would silently drop the watermark. A restored transition's `recordedRevision` must be one a recorded instant can carry (an integer from 1, below `Number.MAX_SAFE_INTEGER`), and the transitions must be in non-decreasing `recordedRevision` order. `importGraph` refuses a document breaking either rule with a `ValidationError` before anything is written; `importGraphStream` validates each `identity-transitions` chunk when it arrives, in order across chunks as well as within one, after the stream's node, edge and assertion chunks have committed. A stream whose header announces a restore (`hasTransitions`, or a non-zero `retention` watermark) but that ends without an `identity-transitions` chunk is refused at its end with `IDENTITY_IMPORT_STREAM_TRANSITIONS_MISSING`. A `state`-mode document carrying `transitions` or a `retention` watermark is refused before anything is written (`IDENTITY_STATE_IMPORT_TRANSITIONS`, `IDENTITY_STATE_IMPORT_RETENTION`), and a zero watermark restores nothing, so it is accepted by any target. diff --git a/apps/docs/src/content/docs/graph-merge.md b/apps/docs/src/content/docs/graph-merge.md index 3db2603d7..01040f694 100644 --- a/apps/docs/src/content/docs/graph-merge.md +++ b/apps/docs/src/content/docs/graph-merge.md @@ -1875,7 +1875,9 @@ tables that removal never finds. no schema.

A role that performs those writes needs `INSERT` and `UPDATE` on that table. Every other holder of the fence — a history-capturing or revision-tracking write, a cardinality, uniqueness or disjointness write, a provenance `holding()` read — takes the lock alone, writes no row and issues the statements it issued before. The row is updated once per deciding transaction, so while a transaction holding an older snapshot stays open (`pg_dump`, a long report, an idle-in-transaction session) its dead versions accumulate and those deciding writes slow until the snapshot closes and the table is vacuumed; see "Write Fence Row" in the limitations guide. - A `store.transaction` whose callback holds a raw SQL handle (`tx.sqlAvailability: "available"`) now takes the per-graph write fence at every constraint-fenced write instead of once per transaction. A `ROLLBACK TO SAVEPOINT` issued through `tx.sql` releases an advisory lock taken after that savepoint and undoes a fence-row advance made after it, so a later fenced write in the same transaction previously ran under a lock it no longer held. Transactions without the handle (history capture, revision tracking, or no native transaction) still take the fence once, and the schema-fence lease follows the same rule. - `TransactionReadBackend`, the `tx.backend` of every transaction context, no longer has `execute`. Its compiled-query brand is a type only, so `tx.backend.execute` ran any SQL on the transaction's session — including a `ROLLBACK TO SAVEPOINT` that released the per-graph write fence and the schema fence while the transaction's later writes kept relying on them, which let two transactions commit a cycle into an `acyclic` relation, and on a history store writes that bypassed capture. `tx.sql` is now the one raw handle a transaction context carries.

The refusal is reachable through `adoptSchemaWriteTransaction` on a caller's `REPEATABLE READ` or `SERIALIZABLE` transaction.

A schema write is every unit that runs under the schema fence: a schema commit or activation from `createStoreWithSchema`, `migrateSchema` or a schema evolution, with the tightening preflight or emptiness probe run before it; an identity schema transition; the graph-merge provenance sidecar claim; removal materialization; and a contribution rebuild. At a snapshot-isolation default the preflight previously read a snapshot taken before the commit waited for the writers holding the schema row, and could activate a tightening such as `acyclic: true` over rows written while it waited. Two caller-owned transactions cannot be moved to `READ COMMITTED` and are now refused when they run at `REPEATABLE READ` or `SERIALIZABLE`: one handed to `adoptSchemaWriteTransaction`, and one under a transaction-scoped backend (`createPostgresTransactionBackend(tx)`, or `createPostgresBackend(tx)` on a transaction), where the schema write runs in a savepoint of the caller's transaction. The second case previously committed and now refuses every schema write above, including the first commit of a brand-new graph, which has no data check: the rule is one per fence, not per write. Run such a schema write in a `READ COMMITTED` transaction. The refusal is raised before the adopted path acquires or changes anything, and the transaction-scoped path rolls its savepoint back, so a caller that catches it keeps its transaction as it was. - At `REPEATABLE READ` or `SERIALIZABLE`, such a PostgreSQL write now fails with SQLSTATE `40001` on that row when another such writer committed past its snapshot, reported as `TransactionConflictError` with the driver error as `cause`. Retry the whole transaction, as for any serialization failure. - A PostgreSQL collection write or import that names a constraint, in a transaction TypeGraph opened, and every `bulkUpsertById`, `bulkReplaceById` and `bulkGetOrCreateByConstraint`, is now replayed up to three times on a serialization failure or deadlock and raises `TransactionConflictError` once the attempts are spent, where the driver error previously propagated from the first failure. A write that names no constraint takes one attempt, as before. SQLite is unchanged. - `getOrCreateByEndpoints` and `bulkGetOrCreateByEndpoints` now accept a `REPEATABLE READ` create leg on the bundled PostgreSQL backends, where it was refused with `MATCH_KEY_CONVERGENCE_REQUIRES_FRESH_SNAPSHOT`.

The copies disagreed: a future validTo gave a part two current wholes behind a released claim, a born-ended history row was probed as a live member (refusing valid creates, imports, branch() clones and merges), a clearValidTo reopen skipped the acyclicity probe, and bulkReparent judged an ended oneActive incumbent as gone from counts and relations that still hold it. - A composition edge write may no longer state a validFrom or validTo later than the operation clock, on every path (partOf on create and get-or-create, edge create/update/upsert and batch forms, import as a per-row error, merge apply through the edge collection), and reparent/bulkReparent refuse a later `at`. CompositionError carries one code per situation (COMPOSITION_WHOLE_OCCUPIED, COMPOSITION_VALIDITY_FUTURE_START, COMPOSITION_VALIDITY_FUTURE_END, COMPOSITION_MOVE_FUTURE) with details discriminated by `situation`. With no scheduled windows, an open-ended row is a membership for good and an ended row is history for good. - One membership predicate, membershipCountsRow over a RowMembership rule, is consumed by the claim set, the composition cascade, the fence audit's holder term, the acyclicity relation's SQL window filter and every row a write hands the probe. ProposedRelationEdge carries its post-write validTo and the probe drops rows its relation does not count. Reopening an ended row probes and fences acyclicity like a create, and batch overlays include reopens. - bulkReparent subtracts an ended oneActive incumbent only from active-only counts, and excludes it from an acyclic relation only when the retire takes it out of that relation. It now fires no operation hooks, like every other batch method. - The merge preview projects each merged edge's resulting window end (reading the stored row when the write states none) and replaces every rewritten row in the walk. - The schema-tightening preflight builds its acyclic relations through the same owner as the write path and probes the composition relation whenever a commit widens its population, not only when it adds a pair. - Export forces temporal fields for graphs with an active-only cardinality axis, as it already does for identity graphs, and refuses an explicit includeTemporal: false there. - subgraph({ composition: true }) walks (kind, id), so a node of another kind sharing an id no longer pulls its parts into the unit. --- .changeset/composition.md | 11 +- apps/docs/src/content/docs/errors.md | 48 ++- apps/docs/src/content/docs/interchange.md | 33 +- apps/docs/src/content/docs/limitations.md | 29 +- apps/docs/src/content/docs/ontology.md | 28 +- apps/docs/src/content/docs/schemas-stores.md | 2 +- packages/typegraph/etc/typegraph.api.md | 19 + .../operations/constraint-fence-audit.ts | 24 +- packages/typegraph/src/errors/index.ts | 158 +++++-- packages/typegraph/src/graph-merge/merge.ts | 64 ++- packages/typegraph/src/interchange/export.ts | 80 +++- packages/typegraph/src/interchange/import.ts | 42 +- packages/typegraph/src/interchange/types.ts | 9 +- .../src/schema/tightening-preflight.ts | 124 ++++-- packages/typegraph/src/store/acyclicity.ts | 145 +++++-- .../src/store/claims/composition-claims.ts | 30 +- .../typegraph/src/store/claims/edge-claims.ts | 55 ++- .../operations/atomic-mutation-program.ts | 5 +- .../store/operations/composition-cascade.ts | 13 +- .../store/operations/composition-create.ts | 162 ++++++- .../store/operations/edge-batch-validation.ts | 68 ++- .../src/store/operations/edge-operations.ts | 359 +++++++++++----- .../src/store/operations/node-operations.ts | 284 +++++++++---- packages/typegraph/src/store/recursive-cte.ts | 51 ++- packages/typegraph/src/store/subgraph.ts | 66 +-- .../integration/composition-attachment.ts | 394 +++++++++++++++++- .../backends/integration/composition-fence.ts | 14 +- .../integration/composition-navigation.ts | 95 ++++- .../integration/composition-tightening.ts | 119 ++++++ .../pglite-edge-acyclicity-query-plan.test.ts | 4 +- .../sqlite/edge-acyclicity-query-plan.test.ts | 4 +- .../tests/composition-portable-probe.test.ts | 7 +- .../tests/composition-reparent-hooks.test.ts | 93 +++++ .../typegraph/tests/edge-acyclicity.test.ts | 31 +- .../graph-merge/edge-acyclicity-merge.test.ts | 155 +++++++ .../composition-history-roundtrip.test.ts | 210 ++++++++++ 36 files changed, 2550 insertions(+), 485 deletions(-) create mode 100644 packages/typegraph/tests/composition-reparent-hooks.test.ts create mode 100644 packages/typegraph/tests/interchange/composition-history-roundtrip.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 122644af0..9f42659cb 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -10,9 +10,11 @@ **`partOf` on `getOrCreateByConstraint` is a POSTCONDITION, not a create-only option**: when the call returns, the resolved node holds exactly the stated attachment. The attachment is resolved before the match is read, so an undeclared whole kind, an unknown `via` and an ambiguous omitted `via` refuse with the same `ConfigurationError` whether the call created the node or found it. A node that already holds this whole through the resolved pair's realizing edge satisfies the call — idempotently when stated `props` are omitted, or valid and value-identical to the edge's live stored props; a valid but DIFFERENT `props` is refused (`CompositionExistenceError`, `situation: "props"`). A stated `validFrom` / `validTo` is held to the same rule: a bound equal to the edge's stored one is satisfied, a different one refuses with `ValidationError` (issue path `partOf.validFrom` / `partOf.validTo`, code `COMPOSITION_ATTACHMENT_WINDOW_CONFLICT`). A node with no live whole has the attachment written now, whatever its pair's declared `existence`, and a resurrection restores the whole alone. A node with a DIFFERENT live whole, or the same whole through another realizing edge, is refused (`situation: "existing"`) naming both sides. `bulkGetOrCreateByConstraint` behaves identically per item and decides its matched items as a set: every verdict a read can reach for an item that matched an existing node — the attachment's (a different whole or realizing edge, differing `props` or window, a dead whole, cardinality, and acyclicity over all of the batch's attachments, counting the attachments of the rows the batch is about to create), on the `ifExists: "update"` and resurrection legs the property update's validation and unique-key probes, and on a resurrection its disjointness and identity-fold checks — precedes the batch's first write, so a refused batch attaches, updates and resurrects nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. Three refusals stay with the write: a new row's own non-attachment refusal (a second unique key it loses, a disjoint kind holding its id), because the unmatched items are created after the matched ones and a matched update may hand them a key; an identity fold that depends on another row the same batch restores; and a concurrent writer the fence does not exclude. A batch with more than one item that owes a write, or one such item next to a new row that states an attachment, pays one extra fenced read pass for this. Bulk writes that do not state a composition attachment keep the established rule: a call that owns its transaction rolls back entirely, while a refusal caught inside an enclosing `store.transaction(...)` can keep the batch's earlier rows, because the operations layer has no savepoints. That includes writing a realizing edge directly: `edges..bulkCreate` and `bulkInsert` decide every item before writing, but `bulkUpsertById` and `bulkGetOrCreateByEndpoints` are ordinary edge batches. Two concurrent get-or-create calls naming DIFFERENT wholes for one part end with exactly one attachment and one `CompositionExistenceError`, never a silent move. When `ifExists: "update"` applies, the attachment and the property update commit together, so any refusal — including a unique or validation error from the update itself — leaves properties, ownership and history untouched, including inside an enclosing `store.transaction(...)`. An already-satisfied call with no update to make stays read-only and takes no write fence. -**A second whole is refused identically on every write path.** `CompositionError` with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`. A backend without claim relations therefore still holds "one whole per part" across two different realizing edge kinds, under the per-graph lock. +**A second whole is refused identically on every write path.** `CompositionError` (`COMPOSITION_WHOLE_OCCUPIED`, `details.situation: "occupied"`) with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`. A backend without claim relations therefore still holds "one whole per part" across two different realizing edge kinds, under the per-graph lock. -**`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. +**A composition window never starts or ends later than its write.** Every write of a realizing edge — `partOf` on every create and get-or-create entry, `store.edges.` `create`, `update`, `upsertById`, `getOrCreateByEndpoints` and their batch forms, validating import (as a per-row error carrying the code) and a graph merge's apply — refuses a `validFrom` later than the operation clock with `CompositionError` (`COMPOSITION_VALIDITY_FUTURE_START`, `situation: "futureStart"`) and a later `validTo` with `COMPOSITION_VALIDITY_FUTURE_END` (`situation: "futureEnd"`), both carrying the stated `bound` and the `operationInstant` it was judged against; `reparent` and `bulkReparent` refuse a later `at` with `COMPOSITION_MOVE_FUTURE` (`situation: "futureMove"`). Each refusal is reached before the write's first statement. This is what makes membership a fact of the row: a composition row with no `validTo` is the part's attachment now and at every later instant, and an ended row is history for good, so the claim, the audit, the delete cascade, the acyclicity check and every current-time read decide which whole a part holds by one rule instead of each choosing an instant — a scheduled end could otherwise leave a part with two current wholes behind a released claim, and a scheduled start a required part with none. `CompositionError.details` is a union discriminated by `situation`. + +**`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. Every write is judged on the row it leaves, by the same rule: a history row created, imported, cloned, merged or restored still ended is outside the union and closes no cycle, while reopening an ended row with `clearValidTo` (`update`, `bulkUpsertById`, `getOrCreateByEndpoints`) puts it back and is probed and fenced like a create — a batch probing its re-admitted rows together before its first write. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not, and a `bulkReparent` that only ends such an incumbent's window still walks it. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. An incumbent a `oneActive` move ends still occupies every bound that counts its whole life (a whole-side `targetCardinality: "one"`, say), so a swap under such a bound is refused at preparation rather than after the windows end. Like every other batch method, `bulkReparent` fires no operation hooks; `reparent` fires one `update` operation naming the part. **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed. Deleting the *whole* still cascades to its required parts — `existence: "required"` governs bare creation and detachment, not whole deletion. `CompositionExistenceError.code` names the situation: `COMPOSITION_WHOLE_REQUIRED` (a bare create), `COMPOSITION_DETACH_REFUSED` (a refused detach), `COMPOSITION_WHOLE_CONFLICT` (a stated `partOf` contradicting the whole an existing node holds) and `COMPOSITION_PROPS_CONFLICT` (a stated `partOf.props` differing from the already-satisfied attachment's stored props). `details.situation` carries the same distinction and remains the discriminant for which optional detail fields are populated, so a handler may branch on either. @@ -24,11 +26,11 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set (`{ expand: "inverse" }`, or the mixed-orientation case `parts()`/`wholes()` now exercise) emitted SQL that PostgreSQL rejected and SQLite accepted.

This applied to create, bulkCreate and bulkInsert, and to the create half of bulkUpsertById and bulkReplaceById, which broke the documented guarantee that a caught bulk refusal leaves none of the batch written. The identity fold is now split into a read that decides it (assertIdentityFoldable, which returns the fold plan) and a write that applies the plan (applyIdentityFold). Every create frame decides its folds before its first write and applies them once the rows land. The verdict is read once: the created row's own write changes neither its live same-id peers nor any class while the frame holds the identity lock. A caller-supplied-id create that folds nothing now also skips the fold's second identity lock. Docs and the changeset now state that the guarantee covers the created row's own fold, and that a converging retry's re-preparation follows the items already written. --- .changeset/bulk-write-verdicts.md | 4 +- apps/docs/src/content/docs/limitations.md | 15 +- .../src/content/docs/performance/overview.md | 16 +- .../src/identity/service-maintenance.ts | 72 +++++++-- packages/typegraph/src/identity/service.ts | 6 +- .../src/store/operations/node-operations.ts | 128 +++++++++------- packages/typegraph/src/store/store.ts | 18 +++ .../integration/batch-write-verdicts.ts | 141 ++++++++++++++++++ .../tests/write-plan-statement-order.test.ts | 12 +- 9 files changed, 321 insertions(+), 91 deletions(-) diff --git a/.changeset/bulk-write-verdicts.md b/.changeset/bulk-write-verdicts.md index 01020df95..0d584b98e 100644 --- a/.changeset/bulk-write-verdicts.md +++ b/.changeset/bulk-write-verdicts.md @@ -2,6 +2,8 @@ "@nicia-ai/typegraph": patch --- -`bulkUpsertById` and `bulkReplaceById` on nodes, and `bulkUpsertById` and `bulkGetOrCreateByEndpoints` on edges, now reach every verdict their items can raise by reading before their first write, so a refusal caught inside `store.transaction(...)` leaves none of the batch written.

The schema-commit preflight probed only acyclicity for that widening, so a part with an ended row under one realizing edge and an open row under another committed with two wholes, and the constraint fence audit reported it right after. The preflight now audits the composition claim family for every realizing edge kind whose row membership widens, decided by one shared rowMembershipWidens predicate that the acyclicity widening check also uses. Also: - a defaulted reparent instant is no longer compared against a second clock read; - subgraph({ composition: true }) resolves a root id held by two kinds to the kind first in code-point order instead of an arbitrary row; - activeOnlyAxisReferences and compositionReentryClaim read the membership rule through axisRowMembership; - two acyclicity relation builders left without outside callers are no longer exported; - the changeset names the real edge collection methods, and the docs describe the widening check and the client-clock caveat. --- .changeset/composition.md | 4 +- apps/docs/src/content/docs/limitations.md | 5 +- apps/docs/src/content/docs/ontology.md | 5 +- .../docs/src/content/docs/schema-evolution.md | 6 ++ .../src/schema/tightening-preflight.ts | 82 +++++++++++++------ packages/typegraph/src/store/acyclicity.ts | 6 +- .../src/store/claims/composition-claims.ts | 3 +- .../typegraph/src/store/claims/edge-claims.ts | 16 +++- .../store/operations/composition-create.ts | 16 ++-- packages/typegraph/src/store/subgraph.ts | 8 +- .../integration/composition-navigation.ts | 10 +++ .../integration/composition-tightening.ts | 82 +++++++++++++++++++ 12 files changed, 197 insertions(+), 46 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index 9f42659cb..d35b4b760 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -12,7 +12,7 @@ **A second whole is refused identically on every write path.** `CompositionError` (`COMPOSITION_WHOLE_OCCUPIED`, `details.situation: "occupied"`) with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`.

It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. Every write is judged on the row it leaves, by the same rule: a history row created, imported, cloned, merged or restored still ended is outside the union and closes no cycle, while reopening an ended row with `clearValidTo` (`update`, `bulkUpsertById`, `getOrCreateByEndpoints`) puts it back and is probed and fenced like a create — a batch probing its re-admitted rows together before its first write. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not, and a `bulkReparent` that only ends such an incumbent's window still walks it. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. An incumbent a `oneActive` move ends still occupies every bound that counts its whole life (a whole-side `targetCardinality: "one"`, say), so a swap under such a bound is refused at preparation rather than after the windows end. Like every other batch method, `bulkReparent` fires no operation hooks; `reparent` fires one `update` operation naming the part. @@ -30,7 +30,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all.

A created composition edge is not evidence on its own — an ended `oneActive` window, or a whole that does not exist (reachable with `validateReferences: false`), leaves the part refused. The check runs to a fixed point, so a required part attached only to a part this import refuses is refused with it, and the result counts track what was committed: a refused part and each edge removed with it come off every `created` and `updated` count this import had added them to, and every removed edge is reported as its own per-row error, including one that was already on the target (written ahead of the part under `validateReferences: false`). A part nothing can attach — no composition edge in the payload names it and the target holds no attachment for it — is refused before its row is written, so no other row is judged against it and the outcome does not depend on row order.

The heterogeneous recorded upsert `tx.writeNodeUpsertBatch()` writes node rows only, so it refuses a required-existence part kind with `ConfigurationError` `HETEROGENEOUS_NODE_BATCH_UNSUPPORTED_KIND` before writing, rather than inserting a part with no whole or resurrecting one the composition cascade deleted. `store.verifyConstraintFences()` gains a `compositionExistence` family reporting any live required-existence part with no live whole, and a `composition` family reporting two or more live edges holding one part's reserved composition axis; a schema commit newly declaring `existence: "required"` on an already-populated pair runs a tightening preflight and refuses a dirty graph rather than silently admitting orphans. A commit that widens the composition relation's population — adding a pair, redeclaring a `oneActive` realizing edge `one`, or declaring `acyclic: true` on one, so its ended rows start to count — probes the whole proposed composition relation for a cycle, built by the same owner the write path uses. `planMerge` and `planMergeIncremental` report composition orphans in `MergePlanReview.compositionOrphans` under two causes: a part attached on the target to a whole the branch deletes, which the plan neither deletes nor moves to another whole (`cause: "deleted"`), and a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all (`cause: "unattached"`).

A schema commit that declares a `partOf`/`hasPart` pair over an edge kind whose non-deleted rows already start or end later than the commit is refused with `MigrationError` (`reason: "ontology-tightening-violated"`) carrying `family: "compositionFutureWindow"` violations, and `store.verifyConstraintFences()` reports the same rows wherever they came from. **`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. Every write is judged on the row it leaves, by the same rule: a history row created, imported, cloned, merged or restored still ended is outside the union and closes no cycle, while reopening an ended row with `clearValidTo` (`update`, `bulkUpsertById`, `getOrCreateByEndpoints`) puts it back and is probed and fenced like a create — a batch probing its re-admitted rows together before its first write. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not, and a `bulkReparent` that only ends such an incumbent's window still walks it. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. An incumbent a `oneActive` move ends still occupies every bound that counts its whole life (a whole-side `targetCardinality: "one"`, say), so a swap under such a bound is refused at preparation rather than after the windows end. Like every other batch method, `bulkReparent` fires no operation hooks; `reparent` fires one `update` operation naming the part. diff --git a/apps/docs/src/content/docs/backend-setup.md b/apps/docs/src/content/docs/backend-setup.md index cf5b5c713..67e8fe331 100644 --- a/apps/docs/src/content/docs/backend-setup.md +++ b/apps/docs/src/content/docs/backend-setup.md @@ -2467,7 +2467,7 @@ for (const violation of await store.verifyConstraintFences()) { ``` `target` exists only on the families that are a contended claim row.

Each of these frames now decides the fold before the row write and applies the decided plan once it lands, through the same assertFoldable/applyFold owner node creates use. The update set behind bulkUpsertById and bulkReplaceById decides each restored row's fold again before that row's write, against the folds its earlier rows applied, instead of after it. With no post-write fold left on the operations layer, the foldCreated identity hook is removed. importGraph still folds its nodes after inserting them: a fold can join two rows of the same document, which no read before their inserts sees. The refusal rejects the whole import and rolls back the transaction the import owns; a shared test now pins that. --- .changeset/bulk-write-verdicts.md | 2 +- apps/docs/src/content/docs/limitations.md | 17 +- .../src/identity/service-maintenance.ts | 4 +- .../src/store/operations/node-operations.ts | 129 ++++++------ packages/typegraph/src/store/store.ts | 16 -- .../integration/batch-write-verdicts.ts | 187 +++++++++++++++++- 6 files changed, 262 insertions(+), 93 deletions(-) diff --git a/.changeset/bulk-write-verdicts.md b/.changeset/bulk-write-verdicts.md index 0d584b98e..a8b297f24 100644 --- a/.changeset/bulk-write-verdicts.md +++ b/.changeset/bulk-write-verdicts.md @@ -6,4 +6,4 @@ `bulkGetOrCreateByEndpoints` re-ran the whole batch once on a `CardinalityError`, also inside a caller's transaction after a create or update of the batch had been written there; it now re-runs only when the refusal left nothing of the batch written (the call opened its own transaction, or no write had run), so a raced batch inside `store.transaction(...)` reports the refusal instead of applying its writes a second time. -A node `create`, `bulkCreate` or `bulkInsert` on an identity graph (`sameIdAcrossKinds: "fold"`) whose caller-chosen id the identity fold refuses now writes nothing: the fold's `IdentityContradictionError` verdict is read before the insert or tombstone resurrection, where it used to follow it, so a refusal caught inside `store.transaction(...)` left the created rows committed.

Each refusal is reached before the write's first statement. This is what makes membership a fact of the row: a composition row with no `validTo` is the part's attachment now and at every later instant, and an ended row is history for good, so the claim, the audit, the delete cascade, the acyclicity check and every current-time read decide which whole a part holds by one rule instead of each choosing an instant — a scheduled end could otherwise leave a part with two current wholes behind a released claim, and a scheduled start a required part with none. `CompositionError.details` is a union discriminated by `situation`. A schema commit that declares a `partOf`/`hasPart` pair over an edge kind whose non-deleted rows already start or end later than the commit is refused with `MigrationError` (`reason: "ontology-tightening-violated"`) carrying `family: "compositionFutureWindow"` violations, and `store.verifyConstraintFences()` reports the same rows wherever they came from. -**`nodes..reparent(id, options)` moves a part to a new whole**, which no sequence of detach and attach could express. `options` is `{ whole, via?, props?, at? }`: the destination attachment and the one instant the move happens at. It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. Every write is judged on the row it leaves, by the same rule: a history row created, imported, cloned, merged or restored still ended is outside the union and closes no cycle, while reopening an ended row with `clearValidTo` (`update`, `bulkUpsertById`, `getOrCreateByEndpoints`) puts it back and is probed and fenced like a create — a batch probing its re-admitted rows together before its first write. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not, and a `bulkReparent` that only ends such an incumbent's window still walks it. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. An incumbent a `oneActive` move ends still occupies every bound that counts its whole life (a whole-side `targetCardinality: "one"`, say), so a swap under such a bound is refused at preparation rather than after the windows end.

Planning now refuses both shapes with MergeCompositionOrphanError. A single classifier, lostBranchAttachment, judges each edge repointEdges drops for a deleted endpoint: a branch-created edge that still attaches its part, whose part is deleted while its whole survives, is cause "moved"; whose whole is deleted while its part survives, is cause "deleted". Both-ends-deleted, non-composition, ended-window and inherited edges stay ordinary drops, and the incremental target's own attachments stay with the existing target-side checks. The finding gains an optional branchId naming the attaching branch. The refusal runs inside plan construction, so merge, mergeIncremental, planMerge, planMergeIncremental and the evolution planners all refuse before any plan or write exists, ahead of the "unattached" report. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/errors.md | 11 +- apps/docs/src/content/docs/graph-merge.md | 25 + apps/docs/src/content/docs/limitations.md | 7 +- .../etc/typegraph-graph-merge.api.md | 1 + .../typegraph/src/graph-merge/edge-repoint.ts | 25 +- packages/typegraph/src/graph-merge/errors.ts | 37 +- packages/typegraph/src/graph-merge/merge.ts | 102 +++- .../typegraph/src/graph-merge/plan-schema.ts | 10 + .../composition-orphan-cross-branch.test.ts | 519 ++++++++++++++++++ 10 files changed, 730 insertions(+), 9 deletions(-) create mode 100644 packages/typegraph/tests/graph-merge/composition-orphan-cross-branch.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 32fd3cba3..9e43fdb43 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -30,7 +30,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all. A cycle refusal names a concrete offending edge: the self-attaching item's own edge for a self-loop, otherwise the first of the batch's edges lying on the cycle. -**Import, the audit and graph merge all see composition.** Validating import tracks every required-existence part it creates and, once the payload's node and edge sets are both known, judges each of them through the same reader the `compositionExistence` audit uses: one attached in the same batch or already attached on the target is accepted, and anything left without a live whole is reported as a per-row error and its node row removed in the same transaction; the rest of the import commits. A created composition edge is not evidence on its own — an ended `oneActive` window, or a whole that does not exist (reachable with `validateReferences: false`), leaves the part refused. The check runs to a fixed point, so a required part attached only to a part this import refuses is refused with it, and the result counts track what was committed: a refused part and each edge removed with it come off every `created` and `updated` count this import had added them to, and every removed edge is reported as its own per-row error, including one that was already on the target (written ahead of the part under `validateReferences: false`). A part nothing can attach — no composition edge in the payload names it and the target holds no attachment for it — is refused before its row is written, so no other row is judged against it and the outcome does not depend on row order. A part a payload edge does name is written and judged afterwards: while its row exists a later row that collides with it is refused against it and is not judged again once the part is removed; re-run the import without the refused part to accept it. An `onConflict: "update"` whose `validTo` would end a live required part's open attachment is refused per row (`COMPOSITION_DETACH_REFUSED`), as the same edge update is through the store. Trusted import refuses every declared composition pair regardless of `existence` (`composition_unsupported`). Streamed import commits each chunk on its own, so a part and the edge attaching it arrive in separate transactions: `importGraphStream` refuses a graph declaring any required-existence part kind before reading a chunk, and `branch()`, `branchForEvolution()` and candidate staging clone such a graph through a single-transaction `importGraph` instead. The heterogeneous recorded upsert `tx.writeNodeUpsertBatch()` writes node rows only, so it refuses a required-existence part kind with `ConfigurationError` `HETEROGENEOUS_NODE_BATCH_UNSUPPORTED_KIND` before writing, rather than inserting a part with no whole or resurrecting one the composition cascade deleted. `store.verifyConstraintFences()` gains a `compositionExistence` family reporting any live required-existence part with no live whole, and a `composition` family reporting two or more live edges holding one part's reserved composition axis; a schema commit newly declaring `existence: "required"` on an already-populated pair runs a tightening preflight and refuses a dirty graph rather than silently admitting orphans. A commit that widens the composition relation's population — adding a pair, redeclaring a `oneActive` realizing edge `one`, or declaring `acyclic: true` on one, so its ended rows start to count — probes the whole proposed composition relation for a cycle, built by the same owner the write path uses; redeclaring a realizing edge so its ended rows count also audits every part those rows attach for a second whole, so a part with an ended row under one realizing edge and an open row under another refuses the commit instead of landing with two wholes. `planMerge` and `planMergeIncremental` report composition orphans in `MergePlanReview.compositionOrphans` under three causes: a part attached on the target to a whole the branch deletes, which the plan neither deletes nor moves to another whole (`cause: "deleted"`); the mirror, a part the plan deletes — directly, or through the branch's cascade from its old whole — that the target has meanwhile moved under another live whole the plan neither deletes nor detaches it from (`cause: "moved"`); and a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all (`cause: "unattached"`). All three are judged against the state the plan would leave: a part the plan deletes or moves to another whole is not a `deleted` orphan, and a required part the plan creates together with its composition edge is not an `unattached` one. A part the plan deletes is still reported as `moved` when the target holds it under a live whole the plan keeps. `planMergeForEvolution()` judges them against the registry the evolution will commit. `applyMergePlan` re-checks `deleted` and `moved` inside the apply transaction under the per-graph write lock, asserts `unattached` for the plan's parts after its last edge in the same transaction, and refuses with `MergeCompositionOrphanError` (`GRAPH_MERGE_COMPOSITION_ORPHAN`), and merge apply deletes nodes with `cascadeComposition: false` so the plan stays the authority over what apply deletes. A branch's composition writes merge as a unit: apply postpones the per-write required-existence rule for the parts the plan touches and asserts it for those same parts after the plan's last edge, in the same transaction, so a required part created with `partOf` and a `reparent` under either cardinality merge like any other edit. One residual gap remains: a composition edge dropped by canonicalization's own endpoint-deleted repointing issues no write for any per-write guard to see, so run `store.verifyConstraintFences()` against a merged store to catch that case; see [Limitations](https://typegraph.dev/limitations#composition-existence-existence-required). +**Import, the audit and graph merge all see composition.** Validating import tracks every required-existence part it creates and, once the payload's node and edge sets are both known, judges each of them through the same reader the `compositionExistence` audit uses: one attached in the same batch or already attached on the target is accepted, and anything left without a live whole is reported as a per-row error and its node row removed in the same transaction; the rest of the import commits. A created composition edge is not evidence on its own — an ended `oneActive` window, or a whole that does not exist (reachable with `validateReferences: false`), leaves the part refused. The check runs to a fixed point, so a required part attached only to a part this import refuses is refused with it, and the result counts track what was committed: a refused part and each edge removed with it come off every `created` and `updated` count this import had added them to, and every removed edge is reported as its own per-row error, including one that was already on the target (written ahead of the part under `validateReferences: false`). A part nothing can attach — no composition edge in the payload names it and the target holds no attachment for it — is refused before its row is written, so no other row is judged against it and the outcome does not depend on row order. A part a payload edge does name is written and judged afterwards: while its row exists a later row that collides with it is refused against it and is not judged again once the part is removed; re-run the import without the refused part to accept it. An `onConflict: "update"` whose `validTo` would end a live required part's open attachment is refused per row (`COMPOSITION_DETACH_REFUSED`), as the same edge update is through the store. Trusted import refuses every declared composition pair regardless of `existence` (`composition_unsupported`). Streamed import commits each chunk on its own, so a part and the edge attaching it arrive in separate transactions: `importGraphStream` refuses a graph declaring any required-existence part kind before reading a chunk, and `branch()`, `branchForEvolution()` and candidate staging clone such a graph through a single-transaction `importGraph` instead. The heterogeneous recorded upsert `tx.writeNodeUpsertBatch()` writes node rows only, so it refuses a required-existence part kind with `ConfigurationError` `HETEROGENEOUS_NODE_BATCH_UNSUPPORTED_KIND` before writing, rather than inserting a part with no whole or resurrecting one the composition cascade deleted. `store.verifyConstraintFences()` gains a `compositionExistence` family reporting any live required-existence part with no live whole, and a `composition` family reporting two or more live edges holding one part's reserved composition axis; a schema commit newly declaring `existence: "required"` on an already-populated pair runs a tightening preflight and refuses a dirty graph rather than silently admitting orphans. A commit that widens the composition relation's population — adding a pair, redeclaring a `oneActive` realizing edge `one`, or declaring `acyclic: true` on one, so its ended rows start to count — probes the whole proposed composition relation for a cycle, built by the same owner the write path uses; redeclaring a realizing edge so its ended rows count also audits every part those rows attach for a second whole, so a part with an ended row under one realizing edge and an open row under another refuses the commit instead of landing with two wholes. `planMerge` and `planMergeIncremental` report composition orphans in `MergePlanReview.compositionOrphans` under three causes: a part attached on the target to a whole the branch deletes, which the plan neither deletes nor moves to another whole (`cause: "deleted"`); the mirror, a part the plan deletes — directly, or through the branch's cascade from its old whole — that the target has meanwhile moved under another live whole the plan neither deletes nor detaches it from (`cause: "moved"`); and a required part this merge writes — or whose composition edge this merge explicitly deletes or ends — that resolves to no live whole at all (`cause: "unattached"`). All three are judged against the state the plan would leave: a part the plan deletes or moves to another whole is not a `deleted` orphan, and a required part the plan creates together with its composition edge is not an `unattached` one. A part the plan deletes is still reported as `moved` when the target holds it under a live whole the plan keeps. Two branches that conflict over one attachment — one moves or attaches a part, another deletes the part or its whole — are refused at plan time by every planning entry point with `MergeCompositionOrphanError` (`cause: "moved"` or `"deleted"`), whose new optional `details.branchId` names the attaching branch; before, the attaching branch's composition edge was silently dropped as `edge:endpoint-deleted`. `planMergeForEvolution()` judges them against the registry the evolution will commit. `applyMergePlan` re-checks `deleted` and `moved` inside the apply transaction under the per-graph write lock, asserts `unattached` for the plan's parts after its last edge in the same transaction, and refuses with `MergeCompositionOrphanError` (`GRAPH_MERGE_COMPOSITION_ORPHAN`), and merge apply deletes nodes with `cascadeComposition: false` so the plan stays the authority over what apply deletes.

The internal option is renamed moveInstant and typed with that brand, endCompositionEdgeWindow and assertCompositionEdgeWindowEndable take one in place of a bare validTo, and a reparent of a part with no incumbent resolves its instant through the same function. No public edge write accepts it. Tests cover a clock step between the move's clock read and its writes (which a fresh clock read refused as a future start), and an edge update or create stating the option, which is still judged at the clock. The docs and the composition changeset state that a move's writes are judged at the move instant. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/ontology.md | 6 +- .../store/operations/composition-create.ts | 25 +++- .../src/store/operations/edge-operations.ts | 47 ++++---- .../src/store/operations/node-operations.ts | 38 ++++-- .../composition-reparent-instant.test.ts | 114 ++++++++++++++++++ 6 files changed, 195 insertions(+), 37 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index 573f15f3e..100b12449 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -12,7 +12,7 @@ **A second whole is refused identically on every write path.** `CompositionError` (`COMPOSITION_WHOLE_OCCUPIED`, `details.situation: "occupied"`) with `details.incumbentEdgeId` is raised whether the claim row or the pre-write probe decides it: a batch, a custom command port that answers `unsupported`, an edge kind declaring both cardinality axes, and a backend that carries no claim relations all count the part's attachments across every realizing edge kind before writing, and report composition ahead of the edge kind's own `CardinalityError`.

It performs both halves in one transaction and validates the final state: one whole, acyclicity over the oriented composition union, and a required part never left detached. That union holds the rows composition counts as memberships, so the ended row a `oneActive` move leaves behind does not constrain later moves, and resurrecting such an ended history row attaches nothing and is not refused because the part now holds another whole. Every write is judged on the row it leaves, by the same rule: a history row created, imported, cloned, merged or restored still ended is outside the union and closes no cycle, while reopening an ended row with `clearValidTo` (`update`, `bulkUpsertById`, `getOrCreateByEndpoints`) puts it back and is probed and fenced like a create — a batch probing its re-admitted rows together before its first write. A realizing edge kind that is also declared `acyclic: true` keeps that declaration's rule: every non-deleted row of the kind counts, ended or not, and a `bulkReparent` that only ends such an incumbent's window still walks it. The part keeps its id, its properties and every descendant beneath it, and a refused move leaves it attached where it was, including inside an enclosing `store.transaction(...)`. How the old attachment retires follows the population declared by the incumbent row's own pair: a `population: "one"` edge is deleted, so the attachment disappears from every `store.asOf(t)` coordinate before the move, while a `population: "oneActive"` edge has its window ended at the move instant, leaving the previous membership readable as valid-time history. That instant — `options.at`, or one clock read when it is omitted — is both the old window's `validTo` and the new edge's `validFrom`, so for a `oneActive` pair the two halves abut: no `store.asOf(t)` coordinate shows the part with zero wholes, and none with two. A `oneActive` window cannot end before it starts: an `at` earlier than the incumbent's `validFrom` refuses before any write with `CompositionError` (`COMPOSITION_MOVE_BEFORE_INCUMBENT`, `situation: "moveBeforeIncumbent"`, naming the incumbent edge and its `validFrom`), and an omitted `at` whose clock read has fallen behind that `validFrom` — the clock stepped backward — moves the part at the incumbent's `validFrom` instead, retiring a zero-width window. `at` is the only temporal option a move takes: a stated `validFrom` or `validTo` refuses with `ValidationError` (issue path `options.`) rather than being dropped, since the move opens the new attachment and bounding a membership is a window edit on the realizing edge. The call returns `{ edge, moved }`: `edge` is the holding realizing edge (the new one, or the incumbent on a no-op) and `moved` is false when the part already held that whole through the same realizing edge. A stated `props` is still checked on that no-op: value-identical to the live stored props the no-op stands, valid but different refuses (`situation: "props"`). `bulkReparent` runs the same operation for many parts in one transaction and reaches every item's verdict before its first write, so a refused batch moves nothing, including when the caller catches the refusal inside an enclosing `store.transaction(...)`. The batch is judged on the state it produces as a whole: two moves that close a cycle between them are refused, a part may move under one the same batch moves out from under it in either item order, and a part listed twice is refused with a `ValidationError`. An incumbent a `oneActive` move ends still occupies every bound that counts its whole life (a whole-side `targetCardinality: "one"`, say), so a swap under such a bound is refused at preparation rather than after the windows end. Like every other batch method, `bulkReparent` fires no operation hooks; `reparent` fires one `update` operation naming the part. diff --git a/apps/docs/src/content/docs/ontology.md b/apps/docs/src/content/docs/ontology.md index 897247996..d9aa228cc 100644 --- a/apps/docs/src/content/docs/ontology.md +++ b/apps/docs/src/content/docs/ontology.md @@ -545,6 +545,9 @@ takes no `validFrom` or `validTo` — stating either is a compile error and a a window edit on the realizing edge.

That row existed at the branch point, so when another branch deletes the whole or the part, the edge deletion absorbed the reopen: it was never staged, never dropped, and never reported, and the part was left with no whole or deleted out from under a surviving one. The cross-branch classifier now also judges those deletion-absorbed copies, and treats an inherited row as a branch attachment when it attaches in the branch's staged copy but not at the merge base, using the same compositionEdgeAttachesPart predicate. StagedEdge carries the base's window end for inherited rows, and withRepointedEndpoints is the one owner of the post-repoint endpoint keys for both sources. Both shapes refuse with the existing causes and branchId; an inherited row that already attached at the base keeps today's behavior. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/errors.md | 4 +- apps/docs/src/content/docs/graph-merge.md | 8 +- apps/docs/src/content/docs/limitations.md | 10 +- .../typegraph/src/graph-merge/edge-repoint.ts | 33 +++- packages/typegraph/src/graph-merge/merge.ts | 180 +++++++++++++----- .../composition-orphan-cross-branch.test.ts | 176 +++++++++++++++++ 7 files changed, 346 insertions(+), 67 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index 9e43fdb43..5d735290b 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -30,7 +30,7 @@ A related defect is fixed: a recursive traversal combining `.recursive()` with a **A batch create whose items carry `partOf` does per-batch rather than per-item work**, with the same refusals: whole rows are read once per kind, a part row is never re-read after the insert that wrote it, and acyclicity is walked once over every composition edge the batch will insert, before the first of them is written — which is what makes a cycle running through two of the batch's own items visible at all.

A parent-kind alias reads each property as the parent declares it: a subclass that omits a parent-optional property, or narrows its type, leaves that property usable in `select()` (decoded as the parent's type on every backend), `whereNode()`, `orderBy()` and `groupBy()`, and `$fulltext.matches()` is available whenever the parent kind declares a `searchable()` field and every subclass either omits it or declares it `searchable()` too. A subclass that redeclares a parent's `searchable()` or `embedding()` field untagged (a legal subtype, since neither annotation is a structural constraint) would leave its rows out of the parent-typed accessor's index, so `$fulltext.matches()` refuses and names the kind, and the embedding accessor is refused as a field the kinds do not agree on. An explicit kind list, `from([...])`, is exact too and takes no options.

A kind whose only equivalence is IRI-routed therefore widens its alias like any other equivalenced kind, and a graph mixing `subClassOf` with `broader` / `inverseOf` / `disjointWith` keeps exact alias types for the kinds no subsumption relation names. The flip side: a relation annotated as the bare `OntologyRelation` widens every alias in that graph conservatively. An endpoint declared as a union of node types keeps its literals and stays precise, widening exactly the kinds the union can hold and nothing else. Known limitation: typed edge collections (`store.edges.`) still type an edge's endpoint by the declared kinds, not by the subclass or equivalent kinds the edge admits at runtime, so `edge.toKind` may be `"Employee"` where it is typed `"Person"`; narrow on the runtime kind before choosing a collection. @@ -23,6 +23,7 @@ - **`QueryAst`'s `start.includeSubClasses: boolean` becomes `start.expansion: "exact" | "subclasses" | "narrower"`.** This affects only code inspecting a compiled AST directly. - **Alias types widen under the polymorphic axis.** For a kind that some other kind declares itself a subclass of, or that participates in a registered-kind `equivalentTo`, the alias's `kind` is `string` and its `NodeId` brand widens.

The persisted projection and schema hash are unchanged; a deserialized document keeps the whole-pair skip, and the live projection keeps the placeholder when the conversion fails for another reason or Zod predates the handler. Removing a persisted relation whose meta-edge is not built in is now classified breaking instead of safe, since no code path can declare it any more and the stored document holds its last copy. The change names the relation in the new OntologyChange.removedCustomRelation, and getMigrationActions lists every such relation in one action, so ensureSchema stops instead of auto-migrating and an explicit migrateSchema() commits the removal. --- .changeset/remove-custom-meta-edge.md | 3 +- .changeset/typed-subsumption.md | 2 +- apps/docs/src/content/docs/ontology.md | 25 +- .../docs/src/content/docs/schema-evolution.md | 41 +-- ...pters-drizzle-postgres-working-copy.api.md | 1 + .../etc/typegraph-graph-merge.api.md | 1 + .../etc/typegraph-interchange.api.md | 1 + .../etc/typegraph-postgres-pglite.api.md | 1 + .../typegraph/etc/typegraph-profiler.api.md | 1 + .../typegraph/etc/typegraph-provenance.api.md | 1 + .../typegraph/etc/typegraph-schema.api.md | 1 + .../etc/typegraph-sqlite-local.api.md | 1 + packages/typegraph/etc/typegraph.api.md | 1 + .../validate-structural-subsumption.ts | 27 +- packages/typegraph/src/schema/migration.ts | 18 +- .../typegraph/src/schema/ontology-change.ts | 74 ++++- packages/typegraph/src/schema/serializer.ts | 2 + .../schema/structural-subtype-projection.ts | 58 +++- .../src/schema/structural-subtype.ts | 27 +- .../tests/meta-edge-removal-migration.test.ts | 142 ++++++++- .../typegraph/tests/ontology-change.test.ts | 2 +- .../tests/typed-subsumption-registry.test.ts | 271 +++++++++++++----- 22 files changed, 548 insertions(+), 153 deletions(-) diff --git a/.changeset/remove-custom-meta-edge.md b/.changeset/remove-custom-meta-edge.md index cc752df9f..dbbb22e7d 100644 --- a/.changeset/remove-custom-meta-edge.md +++ b/.changeset/remove-custom-meta-edge.md @@ -2,7 +2,7 @@ "@nicia-ai/typegraph": minor --- -The public custom `metaEdge()` factory, the public `InferenceType` union, and the deprecated `sameAs`/`differentFrom` type-level factories are removed.

A restored transition's `recorded` is the source graph's instant, typed `RestoredRecordedInstant` (the `RestoredIdentityTransition` variant of `IdentityTransition`, beside `RecordedIdentityTransition`), which `store.asOfRecorded` does not accept. `transitionsOf` and `replay` both page: `limit` caps the number of boundaries one page returns, and a capped page hands back a `nextCursor` to pass as the next call's `cursor`. The cursor is a position within the windowed lineage, so it composes with `fromRecorded`/`toRecorded` by intersection, and `fromRecorded`/`toRecorded` refuse a page cursor with a `ValidationError`. A cursor is bound to the reference whose lineage it pages; one passed to a read of another reference is refused with a `ValidationError`. Bounding the answer with `fromRecorded`/`toRecorded` never bounds the lineage search, so a window can never hide the note that names an earlier class canonical. `store.identity.replay(ref)` pairs each transition with the class membership before and after it, reconstructed through the same historical reader, at the same coordinate, as `store.asOfRecorded`: a step's `after` is what `store.asOfRecorded(step.transition.recorded).identity.membersOf(ref)` answers, and its `before` is the same read one revision earlier. Both are read under the graph's current schema, so a step recorded before a `sameIdAcrossKinds` flip or a kind removal shows that revision as the current schema reads it, and a validity window still open when a step was recorded stays open in that step however late the replay is asked for. Replay requires `history: true` and refuses with `IDENTITY_REPLAY_REQUIRES_HISTORY` otherwise, or with `IDENTITY_REPLAY_ENGINE_NATIVE_UNSUPPORTED` on a backend that owns recorded time itself, where TypeGraph captures no history to replay; Cloudflare D1 and neon-http continue to refuse identity-enabled graphs outright. -A lineage is discovered from the reference itself as well as from its current class, through the recorded `same` assertions and same-id nodes that ever tied it to one, so the history of a member that has since been deleted or split away is still returned from that member.

Every `transitionsOf` and `replay` page carries `completeness` (`IdentityHistoryCompleteness`): `{ status: "complete" }`, or `{ status: "partial", reasons }` listing each `IdentityHistoryIncompleteReason` that holds, so a short or empty page is never mistaken for a complete one. The reasons are `more-pages` (with the `nextCursor` that reads the next page), `retention-truncated` (with the watermark instant `before`, reported by `transitionsOf` as well as `replay`; only `replay` refuses a range wholly below it), `unattributed-restored` (the count of archivally restored transitions discovery can neither tie to the reference nor rule out), `restored-not-reconstructed` (on `replay`, the count of the page's restored transitions that are not `steps`), and `pending-transaction-notes` (on `tx.identity`, when the transaction has made identity changes to the graph that the log does not hold until commit). `IdentityReplayError` (exported from the package root, `details.code` discriminates) is the typed refusal for a request the transition log cannot answer: history capture is off (`IDENTITY_REPLAY_REQUIRES_HISTORY`), the backend keeps engine-native recorded time (`IDENTITY_REPLAY_ENGINE_NATIVE_UNSUPPORTED`), a bounded range lies entirely below the retention watermark (`IDENTITY_REPLAY_HISTORY_TRUNCATED`), the lineage walk reached its read ceiling before converging (`IDENTITY_REPLAY_WALK_INCOMPLETE`), or a prune names a point beyond the recorded clock (`IDENTITY_PRUNE_BEYOND_RECORDED_CLOCK`).

On a transaction's collections it reads under the per-graph write lock the delete takes; on the store's collections it is an unlocked best-effort read. A refused delete is refused with the same error. cascadedParts on delete receipts and operation hooks now carries each part's immediate whole and the composition edge kind that bound it. Pin parts()/wholes() with maxHops: 1 (no depth or path) as the pageable direct-children recipe with a cross-backend test, and correct the docs that said every parts() query refuses pagination. Document subgraph({ composition: true }) as an export rather than a delete preview, and state the cascade's lifecycle right after the first composition example. --- .changeset/composition.md | 12 +- .changeset/paginate-traversal-rows.md | 2 +- apps/docs/src/content/docs/limitations.md | 91 ++-- apps/docs/src/content/docs/ontology.md | 10 +- apps/docs/src/content/docs/queries/execute.md | 5 +- .../src/content/docs/queries/recursive.md | 36 ++ apps/docs/src/content/docs/schemas-stores.md | 30 +- .../typegraph/etc/api-surface-exceptions.json | 64 +++ ...pters-drizzle-postgres-working-copy.api.md | 19 +- .../etc/typegraph-graph-merge.api.md | 21 +- .../etc/typegraph-interchange.api.md | 19 +- .../etc/typegraph-postgres-pglite.api.md | 19 +- .../typegraph/etc/typegraph-profiler.api.md | 19 +- .../typegraph/etc/typegraph-provenance.api.md | 19 +- .../etc/typegraph-sqlite-local.api.md | 19 +- packages/typegraph/etc/typegraph.api.md | 19 +- .../examples/28-composition-lifecycle.ts | 38 +- packages/typegraph/examples/README.md | 2 +- packages/typegraph/scripts/api-report.ts | 35 +- packages/typegraph/src/index.ts | 2 + .../typegraph/src/query/builder/validation.ts | 10 +- .../typegraph/src/store/collection-factory.ts | 6 + .../typegraph/src/store/collection-surface.ts | 3 +- .../src/store/collections/node-collection.ts | 11 + .../store/operations/composition-cascade.ts | 21 +- .../typegraph/src/store/operations/index.ts | 1 + .../src/store/operations/node-operations.ts | 84 +++- packages/typegraph/src/store/store.ts | 7 +- .../src/store/transaction-receipt.ts | 6 +- packages/typegraph/src/store/types.ts | 83 +++- .../tests/backends/integration-test-suite.ts | 2 + .../integration/composition-attachment.ts | 21 +- .../integration/composition-delete-plan.ts | 405 ++++++++++++++++++ .../integration/composition-navigation.ts | 174 ++++++++ .../integration/graph-merge-callbacks.ts | 1 + .../tests/backends/integration/index.ts | 1 + .../concurrent-composition-cascade.test.ts | 58 +++ .../tests/composition-cascade.test.ts | 58 ++- 38 files changed, 1290 insertions(+), 143 deletions(-) create mode 100644 packages/typegraph/tests/backends/integration/composition-delete-plan.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 14ecae618..df90a9eb5 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -20,13 +20,15 @@ **Deleting a composition whole cascades leaf-first through its live parts closure**, each part running through its own node-delete pipeline inside the whole's transaction, with restrict and cascade `onDelete` behaviors on non-composition edges honored per part.

An instance-level cycle among reflexive composition edges is refused with `CompositionCycleError` (`COMPOSITION_CYCLE_DETECTED`) rather than looping or truncating. The closure is read under the per-graph write fence, and the delete and every attach advance the graph's fence row behind it, so on PostgreSQL a `REPEATABLE READ` or `SERIALIZABLE` transaction that cannot see a part attached after its snapshot fails at the fence with a serialization failure instead of deleting from a stale view; a custom backend whose fence advances no fence row refuses the delete at those levels with `ConfigurationError` (`COMPOSITION_CASCADE_REQUIRES_FRESH_SNAPSHOT`). A whole's delete also removes the composition edge of a part that is already tombstoned, and each part's delete releases the unique keys the part holds at that moment.

On a transaction's collections it takes the per-graph write lock the delete takes and holds it to the end of the transaction, so no concurrent attach or reparent can add a part before a `delete(id)` later in that transaction; writes that take no per-graph lock (a detach, a part's own delete, an ordinary edge) can still change the outcome.

With `maxHops: 1` and neither `depth` nor `path`, the step compiles to a fixed one-hop traversal rather than a recursive one, so `paginate()`, `page()` and `stream()` accept it: that is how to page one level of a part tree. `via` narrows the walk to one realizing edge and to the kinds that edge alone reaches, so it works on a multi-level composition and on a whole with several realizing edges; a `via` that realizes no pair at the source alias itself refuses with `ConfigurationError` (`COMPOSITION_VIA_NOT_DECLARED`). `wholes()` is the mirror, returning the ancestor chain.

A root kind declaring no composition parts contributes nothing and the read still runs; a graph declaring no composition relation at all refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED`). Because which composition edge kinds join depends on the root's runtime kind, `composition: true` widens the result's edge-key type to the graph's whole edge-kind union (the new `SubgraphResultEdgeKinds`), so every key the traversal can put in `adjacency` / `reverseAdjacency` is reachable through the result type; `composition` absent or `false` keeps the existing `edges`-list typing unchanged.

All three are judged against the state the plan would leave: a part the plan deletes or moves to another whole is not a `deleted` orphan, and a required part the plan creates together with its composition edge is not an `unattached` one. A part the plan deletes is still reported as `moved` when the target holds it under a live whole the plan keeps.

The schema introspector resolves shared fields per root kind, so an expanded list reads a parent-optional field a subclass omits as the listed kind declares it. When an alias is typed from the compile-time graph, that graph keeps the kind exact, and the live registry expands it further (a subclass added by store.evolve() or reloaded by createStoreWithSchema), from(), list sources, to() and store.search() with expansion: "subclasses" refuse with QUERY_ALIAS_EXPANSION_UNTYPED_SUBCLASSES. The decision lives in expandKindsForAxis, which every surface calls with the typing it gave the alias.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair. Subsumption stays strict — a kind is never its own subclass, and `expandSubClasses` still lists each kind once. External IRIs stay out of subsumption: they are inert references, so `Person ≡ schema:Person ≡ Individual` folds `Person` and `Individual` together without making the IRI a kind. `reconcileTypes` now reads the store's own validated `KindRegistry`, so a merge and a query can no longer disagree about which kinds are the same class, and every kind-name ordering in that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI; an equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. -**`from()`/`to()`/`fromDynamic()`/`toDynamic()` are polymorphic by default**: a query against a supertype returns its subtype rows, typed with the parent's properties, and the alias's `kind` discriminant and `NodeId` brand widen to `string` only for a kind the ontology can actually affect. `queryDefaults.expansion: "exact"` on `createStore(...)` restores the previous exact-kind runtime behavior everywhere in one place (it does not restore the narrow alias types, see Breaking); `search()`, the collection APIs (`find`, `count`, `updateWhere`, `compareAndSet`) and `subgraph({ includeKinds })` are unaffected and stay exact-kind. A parent-kind alias reads each property as the parent declares it: a subclass that omits a parent-optional property, or narrows its type, leaves that property usable in `select()` (decoded as the parent's type on every backend), `whereNode()`, `orderBy()` and `groupBy()`, and `$fulltext.matches()` is available whenever the parent kind declares a `searchable()` field and every subclass either omits it or declares it `searchable()` too.

An explicit kind list, `from([...], alias, options?)`, takes the same `expansion` option and the same store default: each listed kind expands as `from(kind)` would, the union is deduplicated, and the alias types each listed kind as a single-kind alias over it would be. Because the alias type is computed from the compile-time graph, a subclass that only a persisted extension declares (added through `store.evolve()`, or folded back in by `createStoreWithSchema` on a later boot) cannot be typed: when an alias states no `expansion`, its kind is exact in the compile-time graph, and the live schema would expand it to further kinds, `from()`/`to()` refuse with `ConfigurationError` (`QUERY_ALIAS_EXPANSION_UNTYPED_SUBCLASSES`, naming the kind and the extra kinds) instead of returning rows whose `kind` and `NodeId` contradict their type, and so does `store.search()` with `expansion: "subclasses"` on such a kind. State `{ expansion: "subclasses" }` (typed polymorphically) or `{ expansion: "exact" }` on the query, or use `fromDynamic()`/`toDynamic()`. An `updateWhere({ candidates })` query is an ordinary query and follows the default, and a candidate query must resolve to exactly one kind: over a kind with subclasses or `equivalentTo` kinds it is refused with `ConfigurationError` (`SET_UPDATE_CANDIDATE_MULTIPLE_KINDS_UNSUPPORTED`) unless it passes `{ expansion: "exact" }`. **An alias states its expansion as one option**, `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`), on `from()`/`to()`/`fromDynamic()`/`toDynamic()`. `"narrower"` expands a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf`, and types the alias untyped since no schema relationship is claimed. An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, through the same alias typing `from()` uses: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` on a kind the ontology can affect returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`. An options value typed by the library's own `FulltextSearchOptions` / `VectorSearchOptions` / `HybridSearchOptions`, whose `expansion` is optional and either axis, forwards through a caller's wrapper unchanged and types the hit in the widened form. A search that would silently miss rows the index cannot reach is refused with `ConfigurationError` (`SEARCH_EXPANSION_KIND_UNINDEXED`, naming the kinds) instead of under-returning, exactly where `$fulltext.matches()` and the embedding accessor refuse the same alias: a fulltext search of any kind list, exact included, in which a kind has no `searchable()` field or redeclares it untagged, and a vector expansion in which a subclass declares the `embedding()` field with a tag that differs from the subsuming kind's declaration. An exact `store.search.fulltext()` (or hybrid fulltext leg) over a kind that declares no `searchable()` field therefore refuses where it returned `[]`. A subclass that merely omits the field holds no content there and is skipped. @@ -16,6 +16,8 @@ - **`subClassOf`/`equivalentTo` are now generic and carry a structural contract**, which a callers-bypassing path cannot skip: an extension's raw `{ metaEdge: "subClassOf", from, to }` relation and a persisted document are both refused at registry build.

An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, through the same alias typing `from()` uses: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` on a kind the ontology can affect returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`. An options value typed by the library's own `FulltextSearchOptions` / `VectorSearchOptions` / `HybridSearchOptions`, whose `expansion` is optional and either axis, forwards through a caller's wrapper unchanged and types the hit in the widened form. A search that would silently miss rows the index cannot reach is refused with `ConfigurationError` (`SEARCH_EXPANSION_KIND_UNINDEXED`, naming the kinds) instead of under-returning, exactly where `$fulltext.matches()` and the embedding accessor refuse the same alias: a fulltext search of any kind list, exact included, in which a kind has no `searchable()` field or redeclares it untagged, and a vector expansion in which a subclass declares the `embedding()` field with a tag that differs from the subsuming kind's declaration. An exact `store.search.fulltext()` (or hybrid fulltext leg) over a kind that declares no `searchable()` field therefore refuses where it returned `[]`.

An endpoint declared as a union of node types keeps its literals and stays precise, widening exactly the kinds the union can hold and nothing else.

Inside a read-only transaction that ended in a raw driver error on PostgreSQL while SQLite answered a plan. It now refuses up front, before any statement and on every backend, with the read-only UnsupportedBackendCapabilityError that tx.requestRecordedRevision() already raises, naming the store-form preview as the alternative. Both refusals share one helper. The planDelete docs, changeset and limitations now say what the preview actually writes (no graph, sidecar, history or revision row; the transactional form takes the delete's lock), that it fails the way the delete's fence fails under REPEATABLE READ / SERIALIZABLE, and that re-attaching a cascaded tree needs the deleted root restored first. --- .changeset/composition.md | 4 +- apps/docs/src/content/docs/graph-merge.md | 5 +- apps/docs/src/content/docs/limitations.md | 18 ++++- .../src/store/operations/node-operations.ts | 19 ++++++ .../src/store/operations/write-transaction.ts | 20 ++++++ packages/typegraph/src/store/store.ts | 16 +++-- packages/typegraph/src/store/types.ts | 24 +++++-- .../integration/composition-delete-plan.ts | 68 ++++++++++++++++++- 8 files changed, 158 insertions(+), 16 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index df90a9eb5..cd136bdfc 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -20,9 +20,9 @@ **Deleting a composition whole cascades leaf-first through its live parts closure**, each part running through its own node-delete pipeline inside the whole's transaction, with restrict and cascade `onDelete` behaviors on non-composition edges honored per part.

Composition edges never count as a `restrict` obstacle on either end. An instance-level cycle among reflexive composition edges is refused with `CompositionCycleError` (`COMPOSITION_CYCLE_DETECTED`) rather than looping or truncating. The closure is read under the per-graph write fence, and the delete and every attach advance the graph's fence row behind it, so on PostgreSQL a `REPEATABLE READ` or `SERIALIZABLE` transaction that cannot see a part attached after its snapshot fails at the fence with a serialization failure instead of deleting from a stale view; a custom backend whose fence advances no fence row refuses the delete at those levels with `ConfigurationError` (`COMPOSITION_CASCADE_REQUIRES_FRESH_SNAPSHOT`). A whole's delete also removes the composition edge of a part that is already tombstoned, and each part's delete releases the unique keys the part holds at that moment.

Inside `store.transaction(fn, { accessMode: "read_only" })` the transactional form refuses before any statement, on every backend and for every kind, with `UnsupportedBackendCapabilityError` naming the store's `planDelete` as the unlocked alternative. **`QueryBuilder` gains `parts()` and `wholes()`**, declared-structure sugar over the recursive `Traversal` AST for a declared composition relation. `parts("alias", { from?, maxHops?, depth?, path?, via? })` derives the edge kind(s) and direction(s) from the registry's composition relation and recurses to the full transitive closure by default, with no hop ceiling, so a chain of any depth returns whole rather than a bare `.recursive()`'s implicit 10; a `maxHops` you state bounds the walk exactly as given (up to 1000), and `maxHops: 1` reaches the direct level only. With `maxHops: 1` and neither `depth` nor `path`, the step compiles to a fixed one-hop traversal rather than a recursive one, so `paginate()`, `page()` and `stream()` accept it: that is how to page one level of a part tree. `via` narrows the walk to one realizing edge and to the kinds that edge alone reaches, so it works on a multi-level composition and on a whole with several realizing edges; a `via` that realizes no pair at the source alias itself refuses with `ConfigurationError` (`COMPOSITION_VIA_NOT_DECLARED`). `wholes()` is the mirror, returning the ancestor chain. Direction is derived per realizing edge kind: a `part -> whole` edge is followed reversed, a `whole -> part` (`has_*`) edge in its own direction, and a relation realized by both orientations across levels compiles to one traversal step. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the closure under a kind may span several node kinds with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows, and `expand` is not accepted on either step. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()`/`toDynamic()` for an explicit, already-resolved set of target node kinds. `VariableLengthSpec` gains `exhaustive?: boolean`, which walks every path to its end with no hop ceiling and is what `parts()`/`wholes()` set when no `maxHops` is stated. It requires `cyclePolicy: "prevent"` and cannot also state a `maxDepth`; the compiler refuses either contradiction with `UnsupportedPredicateError` rather than ignoring the bound. The walk carries one path per row to prevent cycles, so on a chain deeper than a few thousand levels its cost grows faster than `subgraph({ composition: true })`'s set-semantics closure; the result is complete either way. diff --git a/apps/docs/src/content/docs/graph-merge.md b/apps/docs/src/content/docs/graph-merge.md index 2135cf724..387cc24a3 100644 --- a/apps/docs/src/content/docs/graph-merge.md +++ b/apps/docs/src/content/docs/graph-merge.md @@ -730,7 +730,10 @@ accepts the same two.

A list source is refused only for an extra kind no listed kind's type admits, decided in alias-expansion.ts, and the refusal names the surface it advises. A set-update candidate refusal advises from the kinds the source named rather than the resolved axis. Docs and the changeset state that the refusal reads runtime ontology values, so it also fires for a store typed over a widened graph type or an erased ontology. --- .changeset/typed-subsumption.md | 8 +- apps/docs/src/content/docs/fulltext-search.md | 35 ++--- .../docs/src/content/docs/graph-extensions.md | 17 +- apps/docs/src/content/docs/queries/source.md | 27 +++- .../typegraph/etc/api-surface-exceptions.json | 64 ++++++++ ...pters-drizzle-postgres-working-copy.api.md | 7 +- .../etc/typegraph-graph-merge.api.md | 7 +- .../etc/typegraph-interchange.api.md | 7 +- .../etc/typegraph-postgres-pglite.api.md | 7 +- .../typegraph/etc/typegraph-profiler.api.md | 7 +- .../typegraph/etc/typegraph-provenance.api.md | 7 +- .../etc/typegraph-sqlite-local.api.md | 7 +- packages/typegraph/etc/typegraph.api.md | 7 +- packages/typegraph/src/query/builder.ts | 1 + .../src/query/builder/alias-expansion.ts | 147 +++++++++++++----- .../src/query/builder/executable-query.ts | 6 +- .../src/query/builder/query-builder.ts | 26 ++-- .../src/query/builder/traversal-builder.ts | 5 +- packages/typegraph/src/query/builder/types.ts | 5 + packages/typegraph/src/store/search-facade.ts | 31 ++-- packages/typegraph/src/store/search.ts | 14 +- .../integration/ontology-typed-subsumption.ts | 131 ++++++++++++++-- .../backends/integration/set-node-mutation.ts | 44 ++++++ .../tests/drizzle-claim-sites.test.ts | 2 +- .../tests/field-tracker-proxy.test.ts | 1 + .../typegraph/tests/result-mapper.test.ts | 1 + packages/typegraph/tests/smart-select.test.ts | 1 + .../tests/typed-subsumption-types.test.ts | 33 +++- 28 files changed, 506 insertions(+), 149 deletions(-) diff --git a/.changeset/typed-subsumption.md b/.changeset/typed-subsumption.md index 7042028a1..a1023c377 100644 --- a/.changeset/typed-subsumption.md +++ b/.changeset/typed-subsumption.md @@ -6,9 +6,9 @@ **`equivalentTo` between two registered kinds means mutual subsumption**, and every reading of "same class" now agrees with it: `isAssignableTo`, `isSubClassOf`, `expandSubClasses`, `getSubClassComponent`, disjointness propagation, edge-endpoint admission, query expansion and uniqueness fencing. With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair.

A subclass that redeclares a parent's `searchable()` or `embedding()` field untagged (a legal subtype, since neither annotation is a structural constraint) would leave its rows out of the parent-typed accessor's index, so `$fulltext.matches()` refuses and names the kind, and the embedding accessor is refused as a field the kinds do not agree on.

The flip side: a relation annotated as the bare `OntologyRelation` widens every alias in that graph conservatively. An endpoint declared as a union of node types keeps its literals and stays precise, widening exactly the kinds the union can hold and nothing else. Known limitation: typed edge collections (`store.edges.`) still type an edge's endpoint by the declared kinds, not by the subclass or equivalent kinds the edge admits at runtime, so `edge.toKind` may be `"Employee"` where it is typed `"Person"`; narrow on the runtime kind before choosing a collection. @@ -17,14 +17,14 @@ - **`subClassOf`/`equivalentTo` are now generic and carry a structural contract**, which a callers-bypassing path cannot skip: an extension's raw `{ metaEdge: "subClassOf", from, to }` relation and a persisted document are both refused at registry build.

To keep the previous row behavior everywhere, pass `createStore(graph, backend, { queryDefaults: { expansion: "exact" } })`; per call site, pass `{ expansion: "exact" }`. Omitting the option no longer stops expansion. The store default governs which rows come back, not how an alias is typed: see the alias-type bullet below.

To keep the previous rows, state `from([...], alias, { expansion: "exact" })`, or set `queryDefaults: { expansion: "exact" }` on the store.

Pass `{ expansion: "exact" }` to the candidate query's `from()`. A candidate kind with no subclasses or equivalents is unaffected. - **A saved pagination cursor from a supertype query no longer matches that query.** A query whose source now resolves to several kinds orders by an added `kind` tiebreaker before `id`, so a cursor encoded before the upgrade is refused with `ValidationError` (cursor column mismatch). Restart pagination from the first page, or pass `{ expansion: "exact" }` to keep the single-kind order the cursor was encoded against. - **The `includeSubClasses` boolean is replaced by one `expansion` option** on `from()`/`to()`/`fromDynamic()`/`toDynamic()`: `{ includeSubClasses: false }` becomes `{ expansion: "exact" }` and `{ includeSubClasses: true }` becomes `{ expansion: "subclasses" }`, which is now also what an omitted option means. `store.search()`'s `includeSubClasses: true` (the `includeSubClasses` member of `SearchScopeOptions`) becomes `expansion: "subclasses"`. `createStore(..., { queryDefaults: { expansion } })` and `createQueryBuilder`'s `defaultExpansion` set the default everywhere in one place. A value outside the accepted set is refused with `QUERY_ALIAS_EXPANSION_INVALID`, and so is a stated `includeSubClasses` from untyped code, on every one of those entry points and on `store.search()` (the message names `expansion`): the option is never read as "no option", so a JavaScript `{ includeSubClasses: false }` cannot silently become the polymorphic default. - **The internal `SchemaIntrospector` replaces `hasSearchableField` with `kindsWithoutSearchableField`**, which answers the same question and names the kinds that leave an alias without searchable content, and gains `kindsRedeclaringEmbeddingUntagged`.

A graph declaring no subsumption relations is unaffected.

SubsumedNodeReference owns the widened `{ kind: string, id }` arm with the widened NodeId brand, for affected kinds only. EdgeEndpointRef uses it in place of the polymorphic-node arm, and the new GraphNodeReferenceInput (GraphNodeReference plus that arm) types the bulkFindEdgesFrom/To sources and targets and the neighbors/countNeighbors source on the store, on transactions and in batchOnce. An unregistered kind is still refused at runtime with KindNotFoundError. getNodeByRef and getNodeCollectionOrThrow now refuse an unregistered kind through assertRegisteredNodeKinds, the shared registration check, instead of their own inline copies. The docs and changeset now describe the structural admission correctly: any node or reference whose properties include the declared kind's compiles at an affected endpoint. They also say that an OntologyRelation annotation widens every typed edge endpoint, and they list neighbors() among the widened read surfaces. --- .changeset/typed-subsumption.md | 6 +- apps/docs/src/content/docs/ontology.md | 30 +++-- ...pters-drizzle-postgres-working-copy.api.md | 46 ++++--- .../etc/typegraph-graph-merge.api.md | 46 ++++--- .../etc/typegraph-interchange.api.md | 46 ++++--- .../etc/typegraph-postgres-pglite.api.md | 46 ++++--- .../typegraph/etc/typegraph-profiler.api.md | 46 ++++--- .../typegraph/etc/typegraph-provenance.api.md | 46 ++++--- .../etc/typegraph-sqlite-local.api.md | 46 ++++--- packages/typegraph/etc/typegraph.api.md | 46 ++++--- packages/typegraph/scripts/api-report.ts | 39 +++--- packages/typegraph/src/index.ts | 2 + packages/typegraph/src/store/neighbors.ts | 12 +- .../src/store/node-reference-read.ts | 19 ++- packages/typegraph/src/store/store-view.ts | 7 +- packages/typegraph/src/store/store.ts | 42 +++---- packages/typegraph/src/store/types.ts | 71 ++++++++--- .../integration/ontology-typed-subsumption.ts | 102 ++++++++++++++++ .../tests/typed-subsumption-types.test.ts | 114 ++++++++++++++++++ 19 files changed, 604 insertions(+), 208 deletions(-) diff --git a/.changeset/typed-subsumption.md b/.changeset/typed-subsumption.md index a4d156cfd..3b5265e25 100644 --- a/.changeset/typed-subsumption.md +++ b/.changeset/typed-subsumption.md @@ -10,7 +10,7 @@ **An alias states its expansion as one option**, `expansion: "exact" | "subclasses" | "narrower"` (default `"subclasses"`), on `from()`/`to()`/`fromDynamic()`/`toDynamic()`. `"narrower"` expands a kind through its `broader`/`narrower` kind-taxonomy relations instead of `subClassOf`, and types the alias untyped since no schema relationship is claimed. An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, through the same alias typing `from()` uses: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` on a kind the ontology can affect returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`. An options value typed by the library's own `FulltextSearchOptions` / `VectorSearchOptions` / `HybridSearchOptions`, whose `expansion` is optional and either axis, forwards through a caller's wrapper unchanged and types the hit in the widened form. A search that would silently miss rows the index cannot reach is refused with `ConfigurationError` (`SEARCH_EXPANSION_KIND_UNINDEXED`, naming the kinds) instead of under-returning, exactly where `$fulltext.matches()` and the embedding accessor refuse the same alias: a fulltext search of any kind list, exact included, in which a kind has no `searchable()` field or redeclares it untagged, and a vector expansion in which a subclass declares the `embedding()` field with a tag that differs from the subsuming kind's declaration. An exact `store.search.fulltext()` (or hybrid fulltext leg) over a kind that declares no `searchable()` field therefore refuses where it returned `[]`. A subclass that merely omits the field holds no content there and is skipped. -**Every meta-edge factory now returns a relation typed with its meta-edge name literal and its endpoint kinds**, not only `subClassOf`/`equivalentTo`, the IRI overload (`equivalentTo(Kind, iri)`, typed `from: Kind, to: string`) included.

A deserialized document has no Zod schemas and stores such a kind without a property projection, so its own registry check skips a pair with that kind on either side; every commit, `createStore`, `getSchemaChanges` and `requiresMigration` also check the code graph. **`equivalentTo` between two registered kinds means mutual subsumption**, and every reading of "same class" now agrees with it: `isAssignableTo`, `isSubClassOf`, `expandSubClasses`, `getSubClassComponent`, disjointness propagation, edge-endpoint admission, query expansion and uniqueness fencing. With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair. Subsumption stays strict — a kind is never its own subclass, and `expandSubClasses` still lists each kind once. External IRIs stay out of subsumption: they are inert references, so `Person ≡ schema:Person ≡ Individual` folds `Person` and `Individual` together without making the IRI a kind. `reconcileTypes` now reads the store's own validated `KindRegistry`, so a merge and a query can no longer disagree about which kinds are the same class, and every kind-name ordering in that path is code-point order. `equivalentTo`'s left parameter widens to `NodeType | AnyEdgeType` so an edge kind can be mapped to an external IRI; an equivalence class that mixes node and edge kinds, or that contains more than one registered edge kind (reachable transitively through a shared IRI), is refused at registry build and at schema load with `ConfigurationError` code `ONTOLOGY_EQUIVALENCE_INVALID_CLASS`. diff --git a/apps/docs/src/content/docs/errors.md b/apps/docs/src/content/docs/errors.md index 6b0633a9e..86096127b 100644 --- a/apps/docs/src/content/docs/errors.md +++ b/apps/docs/src/content/docs/errors.md @@ -1710,6 +1710,16 @@ try { } ``` +The `details.reason` value `"custom-relation-removal"` means +`store.evolve()`, `store.planEvolution()` or `store.removeKinds()` would drop a +stored relation that names a custom meta-edge from the removed `metaEdge()` +factory.

An alias cannot state two axes at once; a value outside the three is refused (`QUERY_ALIAS_EXPANSION_INVALID`), as is a narrower expansion naming an unregistered kind or, on `to()`/`toDynamic()`, a kind the traversed edge does not admit as an endpoint (`ONTOLOGY_NARROWER_KIND_NOT_REGISTERED` / `ONTOLOGY_NARROWER_ENDPOINT_NOT_ADMITTED`). Endpoint admission is read from the edge's registration, so it holds whether the endpoints are declared on the edge type or on the graph's `{ type, from, to }` entry; `toDynamic()` refuses a target kind such a registration does not admit with `EndpointError` the same way. Omitting the options argument, passing `{}` and passing an explicit `undefined` all mean "take the store default", so an options bag forwards through a caller's own helper without special-casing the empty case; `queryDefaults.expansion` and `createQueryBuilder`'s `defaultExpansion` accept a stated `undefined` too. Any other default outside `"exact"` / `"subclasses"`, `"narrower"` included, is refused with `QUERY_ALIAS_EXPANSION_INVALID` when the store or builder is constructed rather than at the first alias that falls back to it. A bag that can carry an axis the call site does not pin, such as `{ expansion?: "exact" }`, forwards as well and types its alias untyped, as `"narrower"` does. `store.search()` spells the same axis under the same name (`expansion: "exact" | "subclasses"`, default `"exact"`; the search facade is not polymorphic by default). A search hit is typed by the axis it states, as the `from()` alias stating that axis is: `store.search.fulltext` / `vector` / `hybrid` with `expansion: "subclasses"` returns hits whose `node` keeps the searched kind's properties while its `kind` and `NodeId` brand widen, since the row may be a subclass or an equivalent kind, including one only a persisted extension declares; `"exact"` or an omitted option keeps the exact type, and an `expansion` value that is not a literal at the call site types the hit in the widened form. Spelling the kind generic by hand, `store.search.fulltext<"Doc">(...)`, takes the exact overload, or the widened one when the call states an `expansion`. An options value typed by the library's own `FulltextSearchOptions` / `VectorSearchOptions` / `HybridSearchOptions`, whose `expansion` is optional and either axis, forwards through a caller's wrapper unchanged and types the hit in the widened form. A search that would silently miss rows the index cannot reach is refused with `ConfigurationError` (`SEARCH_EXPANSION_KIND_UNINDEXED`, naming the kinds) instead of under-returning, exactly where `$fulltext.matches()` and the embedding accessor refuse the same alias: a fulltext search of any kind list, exact included, in which a kind has no `searchable()` field or redeclares it untagged, and a vector expansion in which a subclass declares the `embedding()` field with a tag that differs from the subsuming kind's declaration. An exact `store.search.fulltext()` (or hybrid fulltext leg) over a kind that declares no `searchable()` field therefore refuses where it returned `[]`. A subclass that merely omits the field holds no content there and is skipped. -**Every meta-edge factory now returns a relation typed with its meta-edge name literal and its endpoint kinds**, not only `subClassOf`/`equivalentTo`, the IRI overload (`equivalentTo(Kind, iri)`, typed `from: Kind, to: string`) included. A kind whose only equivalence is IRI-routed therefore widens its alias like any other equivalenced kind, and a graph mixing `subClassOf` with `broader` / `inverseOf` / `disjointWith` keeps exact alias types for the kinds no subsumption relation names. The flip side: a relation annotated as the bare `OntologyRelation` widens every alias in that graph conservatively. An endpoint declared as a union of node types keeps its literals and stays precise, widening exactly the kinds the union can hold and nothing else. Typed edge collections (`store.edges.`, the view and recorded-time collections, `bulkFindEdgesFrom`/`bulkFindEdgesTo` and the edges `neighbors()` returns) type each declared endpoint through the same alias typing (`SubsumedNodeType`): an endpoint kind the ontology can affect reads back with a `string` kind and a widened `NodeId` brand, and endpoint arguments accept a node or `{ kind, id }` of any kind assignable to the declared one (`AssignableNodeKinds`, transitive over `subClassOf` and `equivalentTo`) and a polymorphic query row or widened endpoint reference (`{ kind: edge.toKind, id: edge.toId }`), so a subclass row from a supertype query connects without a cast. `bulkFindEdgesFrom`/`bulkFindEdgesTo` sources and targets and the `neighbors()`/`countNeighbors()` source accept the same widened reference, so an endpoint read off one edge feeds the next hop as it is. The widened arm is structural: a node or reference of an unrelated kind whose properties include the declared kind's also compiles, and the runtime refuses it (`EndpointError` on an edge write, `KindNotFoundError` for an unregistered kind). The new `store.getNodeByRef({ kind, id })` (also on transactions and views) reads the node a reference names through that kind's collection, typed as the kind's node for a literal kind and as the kind-discriminated union of the graph's node types plus the base `Node` for a `string` kind; it returns `undefined` for a missing node and rejects with `KindNotFoundError` for an unregistered kind. +**Every meta-edge factory now returns a relation typed with its meta-edge name literal and its endpoint kinds**, not only `subClassOf`/`equivalentTo`, the IRI overload (`equivalentTo(Kind, iri)`, typed `from: Kind, to: string`) included.

This covers the cross-request flow where a user confirms a preview in a later request and no lock can span the gap. A difference refuses with the new NodeDeletePlanMismatchError (NODE_DELETE_PLAN_MISMATCH, situation "changed" naming parts and edge ids added and dropped, or "notLive" for a node deleted since the preview) before any write. The comparison has one owner (node-delete-expectation.ts) and is order-insensitive: parts compare by (kind, id, whole, viaEdgeKind), edges by id. planDelete and the guarded delete share one plan projection (nodeDeletePlanOf), and a guarded delete judges its root so the root's own removed edges are compared. nodeDeleteRequiresPortablePath now owns every request-shaped routing dimension, so a guarded delete never reaches the fused single-statement delete. Options of the wrong shape, { expect: undefined } and duplicated entries are refused with ValidationError; expect is required once options are passed, so planDelete's undefined cannot be passed as an expectation. hardDelete and bulkDelete take no expect: a hard delete also purges tombstoned nodes and soft-deleted edge rows the plan does not name. The composition docs gain an "Undoing a cascading delete" recipe (capture the whole and the planned parts with their props, then recreate whole-first with the same ids and partOf), backed by a test that runs the documented blocks. --- .changeset/composition.md | 6 +- apps/docs/src/content/docs/errors.md | 34 +++ apps/docs/src/content/docs/limitations.md | 4 +- apps/docs/src/content/docs/ontology.md | 115 +++++++- apps/docs/src/content/docs/schemas-stores.md | 14 +- ...pters-drizzle-postgres-working-copy.api.md | 19 +- .../etc/typegraph-graph-merge.api.md | 19 +- .../etc/typegraph-interchange.api.md | 19 +- .../etc/typegraph-postgres-pglite.api.md | 19 +- .../typegraph/etc/typegraph-profiler.api.md | 19 +- .../typegraph/etc/typegraph-provenance.api.md | 19 +- .../etc/typegraph-sqlite-local.api.md | 19 +- packages/typegraph/etc/typegraph.api.md | 30 +- packages/typegraph/scripts/api-report.ts | 31 ++- packages/typegraph/src/errors/index.ts | 66 +++++ packages/typegraph/src/errors/validation.ts | 4 +- packages/typegraph/src/graph-merge/merge.ts | 2 +- packages/typegraph/src/index.ts | 3 + .../typegraph/src/store/collection-factory.ts | 1 + .../src/store/collections/node-collection.ts | 8 +- .../operations/atomic-mutation-program.ts | 8 +- .../operations/node-delete-expectation.ts | 194 +++++++++++++ .../src/store/operations/node-operations.ts | 75 +++-- .../store/operations/node-write-pipeline.ts | 49 ++-- packages/typegraph/src/store/runtime-port.ts | 15 +- packages/typegraph/src/store/store.ts | 10 +- packages/typegraph/src/store/types.ts | 62 ++++- .../integration/composition-delete-plan.ts | 262 ++++++++++++++++++ .../tests/composition-restore-recipe.test.ts | 158 +++++++++++ .../tests/node-delete-expect.test.ts | 197 +++++++++++++ ...e-policy-root-atomic-bypass-pglite.test.ts | 73 ++++- 31 files changed, 1417 insertions(+), 137 deletions(-) create mode 100644 packages/typegraph/src/store/operations/node-delete-expectation.ts create mode 100644 packages/typegraph/tests/composition-restore-recipe.test.ts create mode 100644 packages/typegraph/tests/node-delete-expect.test.ts diff --git a/.changeset/composition.md b/.changeset/composition.md index 3a7f5db3d..94c543e7a 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -24,6 +24,10 @@ **`nodes..planDelete(id)` previews a delete.** It runs the delete's own planner with every write skipped and returns a `NodeDeletePlan`: `cascadedParts`, in the shape and order the delete reports them, and `removedEdgeIds`, every edge the delete would remove.

A guarded delete always takes the portable delete path, never the fused single-statement delete. `expect` is required once options are passed, so `planDelete`'s `undefined` cannot be passed as an expectation, and options of the wrong shape, `{ expect: undefined }` or a plan naming a part or edge id twice are refused with `ValidationError`. `hardDelete` and `bulkDelete` take no `expect`: a hard delete also purges a tombstoned node and the soft-deleted edge rows at each deleted node, which the plan does not name.

The [composition docs](https://typegraph.dev/ontology#undoing-a-cascading-delete) show how to capture the whole, the parts `planDelete` names and their props before a guarded delete, and how to recreate them whole-first (`cascadedParts` reversed) with their ids and `partOf: { whole, via: viaEdgeKind }`, and say what that does not bring back: the ordinary edges the delete removed, and the composition edges' ids, props and windows unless captured. + **`QueryBuilder` gains `parts()` and `wholes()`**, declared-structure sugar over the recursive `Traversal` AST for a declared composition relation. `parts("alias", { from?, maxHops?, depth?, path?, via? })` derives the edge kind(s) and direction(s) from the registry's composition relation and recurses to the full transitive closure by default, with no hop ceiling, so a chain of any depth returns whole rather than a bare `.recursive()`'s implicit 10; a `maxHops` you state bounds the walk exactly as given (up to 1000), and `maxHops: 1` reaches the direct level only. With `maxHops: 1` and neither `depth` nor `path`, the step compiles to a fixed one-hop traversal rather than a recursive one, so `paginate()`, `page()` and `stream()` accept it: that is how to page one level of a part tree. `via` narrows the walk to one realizing edge and to the kinds that edge alone reaches, so it works on a multi-level composition and on a whole with several realizing edges; a `via` that realizes no pair at the source alias itself refuses with `ConfigurationError` (`COMPOSITION_VIA_NOT_DECLARED`). `wholes()` is the mirror, returning the ancestor chain. Direction is derived per realizing edge kind: a `part -> whole` edge is followed reversed, a `whole -> part` (`has_*`) edge in its own direction, and a relation realized by both orientations across levels compiles to one traversal step. The result alias is untyped (`DynamicNodeType`/`DynamicEdgeType`, reached via `.field(name)`), since the closure under a kind may span several node kinds with different schemas. `parts()`/`wholes()` on a kind declaring no composition parts/wholes refuses with `ConfigurationError` (`COMPOSITION_NO_PARTS_DECLARED` / `COMPOSITION_NO_WHOLES_DECLARED`) rather than returning zero rows, and `expand` is not accepted on either step. `TraversalBuilder` gains `toKindSet(kinds, alias)`, a finalizer parallel to `to()`/`toDynamic()` for an explicit, already-resolved set of target node kinds. `VariableLengthSpec` gains `exhaustive?: boolean`, which walks every path to its end with no hop ceiling and is what `parts()`/`wholes()` set when no `maxHops` is stated. It requires `cyclePolicy: "prevent"` and cannot also state a `maxDepth`; the compiler refuses either contradiction with `UnsupportedPredicateError` rather than ignoring the bound. The walk carries one path per row to prevent cycles, so on a chain deeper than a few thousand levels its cost grows faster than `subgraph({ composition: true })`'s set-semantics closure; the result is complete either way. A related defect is fixed: a recursive traversal combining `.recursive()` with a non-empty inverse edge-kind set (`{ expand: "inverse" }`, or the mixed-orientation case `parts()`/`wholes()` now exercise) emitted SQL that PostgreSQL rejected and SQLite accepted.

Pass `CompositionWholeKinds` as the third argument. `StoreProjection` takes the same `CompositionWholeKinds` per projected kind, so `partOf` and `reparent` stay callable on a projection; a store of another graph is assignable to it only when that graph's collection accepts at least those whole kinds. -- `NodeCollection` gains `reparent(id, options)`, `bulkReparent` and `planDelete(id)`.

It does not: an ordinary edge write takes no lock the delete holds, and PostgreSQL arbitrates SERIALIZABLE only among SERIALIZABLE transactions. The TSDoc, ontology and API reference pages and the changeset now state what each isolation level does: at READ COMMITTED such an edge is removed with the node (or refuses a restrict delete), and at REPEATABLE READ or SERIALIZABLE it stays live on the deleted node, as it does for every delete. The comparison covers what the delete planned, and only a composition whole's delete plans under the per-graph lock; for any other kind every concurrent write can change the answer up to the comparison. hardDelete and bulkDelete take no options; an options argument from an untyped caller is now refused with ValidationError instead of running an unguarded delete. NodeDeletePlanMismatchError moves to category "constraint", like RestrictedDeleteError. New tests: a PostgreSQL case where the guarded delete waits on the fence while a second connection attaches a part (fails if the comparison moves to an unlocked pre-read), a dropped-edge-only mismatch, and the hardDelete/bulkDelete options refusal. --- .changeset/composition.md | 4 +- apps/docs/src/content/docs/errors.md | 7 +- apps/docs/src/content/docs/ontology.md | 55 ++++++++++----- apps/docs/src/content/docs/schemas-stores.md | 8 ++- packages/typegraph/src/errors/index.ts | 9 +-- .../src/store/collections/node-collection.ts | 17 ++++- .../operations/node-delete-expectation.ts | 32 +++++++++ packages/typegraph/src/store/types.ts | 69 ++++++++++++------- .../integration/composition-delete-plan.ts | 39 +++++++++++ .../concurrent-composition-cascade.test.ts | 69 +++++++++++++++++++ .../tests/node-delete-expect.test.ts | 43 +++++++++++- 11 files changed, 293 insertions(+), 59 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index 94c543e7a..685b8095a 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -22,9 +22,9 @@ **A whole's delete says which parts it took.** The delete's `onOperationEnd` hook context and `store.transactionWithReceipt`'s receipt both carry `cascadedParts`, one `CompositionCascadedPart` per part (`{ kind, id, whole, viaEdgeKind }`: the part, the whole it was directly a part of, and the composition edge kind that bound them, enough to re-attach the tree once the deleted whole itself is restored) that never names a part the cascade did not delete, in the cascade's own delete order: leaf-first, then by kind, then id, within one level of the closure.

The cascade now orders member kinds by code point, the order every other multi-kind lock read uses. --- .changeset/composition.md | 2 +- apps/docs/src/content/docs/backend-setup.md | 6 +- apps/docs/src/content/docs/limitations.md | 65 +++++++++++++++---- .../src/store/operations/node-operations.ts | 10 +-- 4 files changed, 65 insertions(+), 18 deletions(-) diff --git a/.changeset/composition.md b/.changeset/composition.md index aa90914f6..45201f5fe 100644 --- a/.changeset/composition.md +++ b/.changeset/composition.md @@ -18,7 +18,7 @@ **Detaching a live required part is refused.** Ending, soft-deleting or hard-deleting a required-existence part's composition edge while the part is LIVE refuses with `CompositionExistenceError` (`COMPOSITION_DETACH_REFUSED`, `situation: "detach"`); detaching from a soft- or hard-deleted part is allowed.

That order is fully deterministic, so the same closure reports the same list on every run and every backend and a consumer may compare `cascadedParts` for equality. The receipt covers `bulkDelete` too, accumulating every item's cascade in batch order (a node an earlier item's cascade deleted is reported once, whichever order the batch names a part and its whole in), and the batch path still emits no per-item operation hooks. A `tx.measure(...)` scope's sub-receipt carries the refs for the deletes issued THROUGH that scope, so a delete issued through the outer transaction during an open scope stays out of it. `onOperationStart` never carries them, and the refs are not folded into the receipt's write counters: one caller-issued delete stays one write intent.

With `equivalentTo(Company, Corporation)`, `isAssignableTo("Corporation", "Company")` is true, a `Company` alias (`expansion: "subclasses"`, the default) returns `Corporation` rows, an edge declared `to: [Company]` accepts a `Corporation` endpoint, `search(..., { expansion: "subclasses" })` covers both kinds, and a `kindWithSubClasses` uniqueness constraint fences across the pair.
