Legacy `datamind_use_folder` and normal live queries +retain their unversioned semantics; a workspace update publishes a separate +snapshot and never silently replaces those live stores. + +Every revision contains copied source bytes, private capability storage, a +source inventory with stable URI-based IDs/content versions, snapshot bindings, +and a processing fingerprint. The SQLite catalog publishes by comparing the +current head with the build's starting head. Concurrent stale builds fail +publication rather than overwriting newer state. A reader owns one revision for +its lifetime; original source URIs in raw-evidence reads resolve to copied bytes. +Workspace inspection is also restricted to the pinned source copy. + +To return to a retained complete generation: + +```python +workspace.rollback(old_revision, expected_revision=workspace.current_revision) +``` + +Completed-source checkpoints include passages, vectors, extracted relationships, +and parsed tables. A new build after process termination reuses these checkpoints; +it does not rerun model calls for already completed sources. A failed source is +retried in full. Index materialization currently writes a new full snapshot: this +is file-granularity compute reuse, not dependency-aware sub-file maintenance or +constant-cost storage. Old snapshots/checkpoints are retained; automatic GC and +exactly-once external writes are not provided. + +The shipped coordinator supports one-host concurrent readers/builders using local +NetworkX, SQLite, and Chroma/LanceDB storage. It rejects external DB DSNs and +unsupported graph providers before building. Multi-host scheduling, tenant +identity/authorization, distributed locks, remote snapshot providers, and service +capacity/load validation remain deployment work. They do not follow from selecting +the Agent SDK backend. Snapshot readers should be reused per request/session as +appropriate; this API currently opens capability services when a reader is opened. + +## PR #28 integration + +LanceDB versioning is opt-in with `pip install 'datamind[versioning]'` and +`DATAMIND__KB__VECTOR_STORE=lancedb`. CocoIndex additionally requires +`pip install 'datamind[cocoindex]'` and `DATAMIND__KB__INGEST_MODE=cocoindex`. +Personal installations keep Chroma/direct ingestion by default. Dolt requires +`pip install 'datamind[dolt]'` and a separately installed Dolt binary/service. + +History records survive process restart; historical LanceDB reads use private +table handles and do not change the writer's checkout. Re-adding a chunk ID is an +upsert. External source copies are keyed by origin so editing one source replaces +its own managed copy rather than accumulating content-hash filenames. Dolt +historical SQL rewrites physical tables using an AST, covering joins and CTEs +without changing string literals. Dolt and external MySQL integration tests need +their services and must not be counted as validated when skipped. + +## Ingestion Skills + +`workspace-ingest` and `source-update` ship in both the checkout and wheel skill +catalogs. StoreAgent has explicitly allowed Skill lookup and input-inspection +reads; business KB/DB/Graph query tools remain RetrieveAgent-only. Skills guide +routing, schemas and receipt inspection; persistence invariants stay in tools. +A successfully fetched Skill contributes its name, declared version and content +hash to subsequent write receipts in that store turn. Fetching records procedural +context, not proof the model followed every instruction. Receipt context does not +leak into another store turn. Partial directory failures produce failed receipts +and are not cached as successful imports. + +Pinned readers retry only transient I/O/timeouts and retryable external-service +errors, with a bounded `read_retries` budget (default 1, configurable from 0 to 5). +Retries use the same revision. After exhaustion the original error is returned to +the Agent, which can use another available evidence path; no answer is fabricated +and no latest-version fallback is made. The query response reports the retry +count. Application-level deadlines and workload evaluations remain the caller's +responsibility. + +Inline graph text and structured assertions without supplied evidence retain +immutable input records under `triplets/evidence/`. These are excluded from KB +raw-document indexing. Explicit assertions are labeled as caller statements, not +independently verified facts. Logical file IDs now derive from canonical URI; +content hashes remain source versions. The receipt ledger migrates legacy JSON +state to SQLite, allocates unique revisions across workers, retains durable +receipts, and keeps the JSONL export for existing tooling. This does not make an +external append write and its receipt an exactly-once distributed transaction. + +## Validation status + +Local validation: 368 package tests passed, 86 skipped; 3 Codex-adapter tests +passed. The SQLite demo and wheel/resource checks passed. Tests use local storage +and deterministic model/embedding doubles. Coverage includes actual hard process +exit, source checkpoint reuse, parallel publication, publication/rollback races, +transient pinned reads, historical table reads, graph evidence replacement, and +Skill receipt isolation. Dolt/MySQL service tests were skipped when unavailable; +live SDK/model integrations, enterprise throughput, and research quality/cost +benchmarks have not been measured. Publication includes a monotonically increasing +epoch so an intervening publication and rollback cannot let a stale builder win. diff --git a/docs/TESTING.md b/docs/TESTING.md new file mode 100644 index 0000000..d89fe61 --- /dev/null +++ b/docs/TESTING.md @@ -0,0 +1,24 @@ +# Automated verification + +Every pull request runs `.github/workflows/python-ci.yml`.
