Here's what changed and how it was verified. ## Notification revert - `test/notificationSchema.test.ts` restored to its pre-`be4ed9a` state (byte-identical to `c67b9cb`). No notification code or other notification tests touched. Reran it: **32/32 pass**, confirming the earlier CI failure was the transient claim-timing flake, not this PR. ## Corrective implementation (all 9 acceptance criteria) 1. **Zero-warning lint via extraction (no rule disables).** `GoalSessionSupervisor.ts` (571→split) and `dockerExecutor.ts` (−179 lines) were decomposed into cohesive modules: `errors.ts`, `recoveryMetadata.ts`, `support.ts`, `GoalSessionCore.ts`, `GoalTurnRunner.ts`, plus `dockerProcessUtils.ts` and `supervisedDockerExecutor.ts`. Every `eslint-disable max-lines/complexity` was removed; all files are ≤365 lines. Legacy one-shot `executeDockerCommand` is unchanged (re-exported for compatibility). 2. **Same-turn pause/resume + crash recovery.** New adapter `resumeTurn(...)` continuation stream and `GoalTurnRunner.resumeTurn` continue the *exact* paused turn to a single later completion, even on a replacement supervisor/new controller epoch. Test proves: pause mid-turn → new supervisor takes over → resume same turn → more ordered events → **exactly one completion**. 3. **Control fencing separated from turn fencing.** Added `GoalSessionControlFence` and `appendControl` (epoch-only) so model-change/cancel/resume/reconcile stay auditable with no active turn; turn IDs are no longer accepted in idle state; terminal events use a session-scoped control identity (never a completed turn). Stale epochs still rejected atomically. 4. **Explicit duplicate semantics.** Duplicate delivery returns `{disposition:'duplicate', reattached:true}` observing durable state — no second provider invocation, no false completion. 5. **Backpressure/bounds.** `OrderedBackpressureSink` pauses/resumes source streams at high/low-water marks, bounds chunk and queued bytes, preserves cross-stream ordering, and cancels with an actionable overflow error. Tests prove bounded memory + ordering + overflow. 6. **Hardened container inputs.** Env passed as `--env NAME` (values injected via client env, never argv); `providerHomeTarget` constrained to provider-owned roots (can't shadow `/`, `/workspace`, etc.); credentials mounted read-only, separate from writable home; symlink/path-escape-safe cleanup. All tested. 7. **Deterministic crash-before-provider-ID recovery.** Initialization intent is persisted before the first provider open; a later controller recovers via deterministic open instead of permanent `INCOMPLETE_INITIALIZATION`. Tests cover kills before and after provider-identity persistence. 8. **Reconcile verifies worktree.** Path/branch/head are checked and a `blocked` result is surfaced *before* any resume side effect. 9. **InMemory ports clearly a test/embedding fake** (`isEphemeralTestDouble`, documented as non-durable), preserving execution/attempt identity. ## Verification - Core `tsc --noEmit`: clean; API typecheck against updated core: clean. - `eslint src/ --max-warnings 0`: **0 problems**, no rule disables. - Focused suite (goal-session + docker, incl. new tests): **24/24 pass**. - Notification schema test rerun: **32/32 pass**. Per the harness rules I did not commit or push (the git index is system-managed and the system commits automatically); the branch remains open. All changes are staged in the working tree for that commit.

Everything is complete and verified. No commit made (per instructions). MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All production files are well within the 400-line limit and lint reported zero warnings. Everything is complete and verified. No commit made (per instructions). ## Summary I addressed all six items from the owner validation follow-up, strictly within #2007 scope, preserving the legacy one-shot executor (`executeDockerCommand`) and touching no notification code. Every item has regression tests. ### Production changes **1. Retention cleanup symlink escape** — `GoalContainerSupervisor.cleanTerminalSession` now proves *lexical/resolved identity* and *derived-layout ownership*: the target must be an immediate child of the real goals dir whose name matches the opaque derived goal-scope pattern, and its symlink-resolved path must be **lexically identical** to its derived path. Any symlink — external *or* an in-tree symlink to a sibling goal's real directory — resolves to a different path and is rejected, so `rm` can never delete another goal's directory. **2. Layout traversal + `--mount` injection** — `buildGoalContainerLayout` now names the log file only from the opaque derived `executionId` (no raw caller `executionId`/`attemptId`), with a defensive assertion that the log path stays inside `sessionRoot/logs`. New `validateBindMountPath` rejects commas/`=`/control chars in every bind-mount field (worktree, credential source/target, provider-home target, base dir) to block Docker `--mount` option injection. **3. Backpressure validation + cap timing + UTF-8** — `resolveBackpressureLimits` requires positive safe-integer limits and enforces a coherent `maxChunkBytes <= maxQueuedBytes` (clamping the per-chunk default when only the queued bound is set). The hard cap is now enforced *inside* the enqueue split loop, so a single oversized read is stopped mid-split instead of fully buffered first. `splitBuffer` backs off UTF-8 continuation bytes so multibyte characters are never cut across chunk boundaries. **4. Crash reconciliation coherence** — `reconcileRecoveredTurn` turns a running/pause-requested/paused turn into an explicitly **paused, resumable** turn on `outcome:'resumed'` (never idle-with-a-live-turn), so a replacement supervisor continues the exact execution/attempt once. `verifyReconciliationTarget` now **blocks** when the expected branch/head cannot actually be observed rather than passing on absence. **5. Provider invocation failures** — `adapter.beginTurn`/`resumeTurn` are now invoked via a factory *inside* `driveTurnStream`'s try/catch, so a synchronous/early throw is normalized into fenced `failed` state plus exactly one completion event. **6. Control/duplicate invariants** — model changes on `cancelling`/`terminated`/`failed` sessions are rejected before the adapter is called. Completed turns' real execution identities are now persisted (`completedTurns`), so a late redelivery of an older turn reattaches to its original execution/attempt; when unrecoverable (legacy state) it returns a truthful `reattached:false`. ### Verification (all run in `packages/core` / repo root) | Command | Result | |---|---| | `npx tsx --experimental-test-module-mocks --test test/goalSessionSupervisor.test.ts test/goalContainerSupervisor.test.ts test/goalContainerHardening.test.ts test/supervisedDockerBackpressure.test.ts test/supervisedDockerExecutor.test.ts` | **36 pass / 0 fail** (12 new) | | `npx tsx --experimental-test-module-mocks --test test/*.test.ts` (full core) | **158 pass / 0 fail** | | core `npx tsc --noEmit` | clean | | core `npx eslint .` | clean (0 warnings — files within limits, no disables) | | api `npx tsc --noEmit` / `npx eslint .` | clean | | root `npx tsc --noEmit` / `npx eslint src/` | clean | Changed production files remain well under the 400-line limit (largest: `GoalSessionSupervisor.ts` at 368 total lines, fewer counted since blanks/comments are skipped), confirmed by zero `max-lines`/`complexity` warnings.

Implemented bounded Phase A only. Key outcomes: - Typed eager/first-turn ID, steering, pause, and model-boundary capabilities. - Lazy native-ID binding without placeholders. - Deterministic after-turn pause/resume and explicit unsupported same-turn outcomes. - FIFO next-turn message delivery and acknowledgements. - Removed touched `max-lines` suppression via an agents barrel. - Added focused capability and supervisor regressions. Validation passed: - 32 focused runtime/backpressure tests - 98 setup smoke tests - Core build, typecheck, zero-warning lint, and `git diff --check` - CLI package smoke (`npm run cli:pack`) Per the harness instruction, I did not commit or push; the system will create the commit. Current unchanged base SHA is `37c2437d409cf74f01e9dfc4a0dd979600f93dbd`. PR remains open, and Phase B was not attempted.

Implemented the bounded Phase B follow-up from head `8d60a45d3817`. Key outcomes: - Fresh durable attempt IDs for provider reopen, reconciliation, resume, and retry; stale-attempt output is rejected. - One-shot CAS ordering prevents delayed same-epoch model, resume, intent, and completion updates from overwriting newer state. - Terminal state and completion events now use an atomic, idempotent transaction port with pre-/post-commit crash coverage. - Reconciliation verifies goal, session, execution epoch, turn, attempt, and worktree fingerprint. - Docker execution uses exact environment and mount allowlists without inheriting host environment. Docker sockets, sensitive directories, broad mounts, aliases, traversal, and symlink paths are rejected. - Output backpressure and cleanup behavior remain covered. - No lint suppressions or deferred items.

Implemented the bounded Phase B follow-up, left uncommitted as instructed. Key changes: - `firstTurnIdCrashPolicy: 'fail'` now atomically records failed completion, clears the active turn, and remains stable across repeated opens. - Deterministic retry recovery remains supported with fresh attempt identities. - First-turn identity binding consumes the deferred requested model, preventing redundant turn-two application. - Successful completion with unacknowledged supplied messages now raises `MESSAGE_ACK_MISSING` and fails the turn. - Added focused regressions in [goalSessionCapabilities.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-08-31T11-17-23/packages/core/test/goalSessionCapabilities.test.ts). Validation: - Focused tests: 33/33 passed - Full core suite: 173/173 passed - TypeScript typecheck passed - Core lint passed with zero warnings - `git diff --check` passed - HEAD remains `48c89c52`; no commit or merge performed.

Implemented the bounded PR #2017 follow-up without committing. - Fixed after-turn completion to settle `paused` when a concurrent pause is already durably `pause_requested`. - Added a deterministic gated TOCTOU regression test. - Removed mutable `headSha` from worktree fingerprints. - Recovery now fingerprints the repository URL, resolved worktree path, and branch observed directly from Git. - Current HEAD remains separately available as checkpoint metadata. - Added tests accepting legitimate HEAD advancement and rejecting repository replacement at the same path without relying on HEAD. Validation: - Core typecheck passed. - Core lint passed with zero warnings. - Focused tests: 36/36 passed. - Broader goal-session/container tests: 54/54 passed. - `git diff --check` passed.

Implemented the PR #2017 owner-validation addendum, scoped to goal-session core only. Key fixes: - Cancellation now durably prevents concurrent completion from resurrecting a session. - Stream mutations fence exact `executionId` and `attemptId`. - Reconciliation tracks recovery attempts separately; `alive`/thrown/blocked preserve live identity, while proven replacement promotes the new attempt. - Added authoritative Git origin, branch, HEAD, root/path regression coverage. - Credential targets reject descendants of `/proc`, `/sys`, and `/dev`. - `layout.logPath` now receives bounded 8 MiB, fenced JSONL output. Validation: - Focused addendum tests: 22 passed. - Full core suite: 191 passed, 0 failed/skipped. - Root and core typechecks passed. - Root and core lint passed with zero warnings. - Diff checks passed, including new files. The shared object database rejected an optional temporary-index check due permissions; the real index was untouched, and equivalent tracked/untracked diff checks passed. No commit, push, merge, or PR creation was performed. HEAD remains `b0c19ba7c381986f6314b24fe8d6794170e597af`.

No merge performed. Implemented the consolidated runtime correction and left it uncommitted for the system to publish. No merge performed. Key outcomes: - Made late after-turn pause boundary plus completion a required, atomic, idempotent terminal transaction. - Applied the latest pending model at recovered discrete invocation boundaries with newer-intent CAS protection. - Added real same-epoch stale-stream tests across reconcile/resume attempts. - Strengthened cancel/completion, reconciliation alive/blocked/thrown/replacement/crash-retry, output fencing, credential-target, and bounded-log regressions. - Preserved allowlists, backpressure, repository identity, and existing capability behavior. - Added no lint suppressions. Validation: - Focused goal/container/backpressure: **74 passed, 0 failed/skipped** - Full core with module mocking: **196 passed, 0 failed/skipped** - Root and core typecheck: passed - Root and core lint with `--max-warnings=0`: passed - Root and core builds: passed - `git diff --check`: passed - Diff: 8 files, 403 insertions, 63 deletions; no untracked files Note: the supplied checkout was already at `6c561b242a106d00b2d868d7a9e605a07554286f`, one commit after requested `b0c19ba7`.

no merge or publication performed. Implemented all five PR #2017 audit fixes and left them uncommitted; no merge or publication performed. Key changes: - Secret-safe output allowlists before delivery and JSONL persistence, including full execution fence and sequence metadata. - Exact `executionId` + `attemptId` fencing for corrective-message acknowledgement. - Lazy-ID pending cancellation primitive with crash/race/idempotency handling and active-turn clearing. - Preserved and verified fresh pending-model application during recovered invocation. - Durable after-turn pause intent with atomic, exactly-once boundary/completion replay across pre/post-commit crashes. Validation passed: - Full core suite with module mocks: 204 passed, 0 failed/skipped. - Root and core typecheck. - Root and core zero-warning lint. - Root and core builds. - `git diff --check`. - No lint/type suppressions or generated tracked artifacts. Primary changes are in [GoalSessionControls.ts](), [GoalSessionCore.ts](), and [supervisedDockerExecutor.ts]().

Implemented all six follow-up blockers at unchanged head `b7a8ee6`. Key fixes: - Explicit secret-safe fence/execution DTO persistence; poison tests inspect raw replay objects and serialized bytes. - Cancellation atomically clears active-turn ownership before provider await and uses durable idempotency identities. - `openSession` resumes bound and lazy-ID cancelling states across crashes and provider races. - Crash-safe model intents with stable adapter idempotency keys across all three crash windows. - Exact-attempt terminal commit retries resolve late pause races canonically. - Atomic state-plus-audit transactions prevent model/pause events after terminal completion. Primary changes are in [contract.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-08-31T13-26-03/packages/core/src/agents/goalSession/contract.ts), [GoalSessionControls.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-08-31T13-26-03/packages/core/src/agents/goalSession/GoalSessionControls.ts), and [goalSessionReaudit.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-08-31T13-26-03/packages/core/test/goalSessionReaudit.test.ts).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented all three re-audit blockers at exact head `10cea2fc` without committing or merging. Key fixes: - Atomic eager pause and streamed `model_changed`/`pause_boundary` state+audit transitions with exact-turn fencing and bounded idempotency keys. - Durable `next_safe_boundary` model phases (`pending → provider_in_doubt → committed`), stable key reuse, reopen reconciliation, and exactly-once audit. - Terminal reconciliation guard: failed/terminated sessions are blocked; cancelling sessions use only stable cancellation recovery. Added comprehensive adversarial coverage in [goalSessionFinalReaudit.test.ts](/home/node/workspace/packages/core/test/goalSessionFinalReaudit.test.ts). Validation passed: - Focused capability/re-audit/recovery/security suites - Full core module-mocked suite - Root and core typechecks - Root and core zero-warning lint - Root and core builds - `git diff --check` - No suppressions added HEAD remains `10cea2fce2ea1f748d593aff25b19f7c4139c4e5`; worktree contains only the bounded source and test changes.

Implemented all four HIGH blockers at exact head `20e53540f55e16862e00e14352d0c0cd931d9075`. Key changes: - Exact execution/attempt and provider occurrence-scoped streamed transition identity, with live-fence validation before dedupe. - Durable model generations with stable identities, stale-completion repair, process-replacement recovery, and exactly-once ordered audit. - Reopen preserves the prior model until unresolved intent recovery atomically commits model plus audit. - Two-phase recovery leasing serializes cancellation against provider reconciliation, including replacement and failed-reconcile recovery. Validation: - Focused capability/re-audit/recovery/container suites: **128/128 passed** - Full core suite with module mocks: **257/257 passed**, 3 suites - Container-security adjuncts: **29/29 passed** - Root and core typechecks: passed - Root and core builds: passed - Root and core lint: passed with **zero warnings** - Diff check and suppression/security scan: clean No commit, push, merge, or PR creation was performed. The PR remains unmerged as requested.

Implemented all five HIGH blockers at unchanged head `a0012162d0d004aafca99f920fa8d72c146944c0`. Key changes: - Durable recovery leases/tokens with exact status, execution, attempt, epoch, and provider-call fencing. - Cancellation preempts recovery without process-local waits; removed the `WeakMap` coordinator. - Generation-scoped model application leases with cross-process convergence and provider generation fencing. - Stable streamed occurrence identities with ID precedence, ordinal validation, replay deduplication, and fail-closed handling. - Atomic recovery/session-resume state and audit transactions with crash-replay receipts and terminal ordering. - Cross-process tests use independent SQLite connections, not shared in-memory ports or locks. Validation: - Exact-head suite: **27 passed** - Focused recovery/supervisor/container suites: **160 passed** - Full core with module mocks: **273 passed** - Container-security adjuncts: **34 passed** - Core and root typecheck: **2 passed** - Core and root lint: **0 errors, 0 warnings** - Core and root builds: **2 passed, 0 warnings** - `git diff --check` and final suppression/security scans: clean No commit was created and the PR remains unmerged.

Implemented the queued owner addendum at exact head `71ce3854e28f48cf5e70a9d0ceb55fae7d854bb4`. - Added deterministic model-intent compaction: latest 64 settled generations plus all unresolved work, with reopen migration, cached acknowledgements, monotonic generations, and complete event replay. - Canonicalized credential-bearing HTTPS, SSH, and scp Git remotes before state/provider/event/error boundaries; malformed identities fail closed. - Added adversarial coverage in [goalSessionQueuedOwnerAddendum.test.ts]() and [goalSessionRecovery.test.ts](). Validation passed: - 136 goal-session runtime/recovery tests - 22 Docker hardening/backpressure tests - 11 security tests - Root typecheck - Core zero-warning lint - Core build - `git diff --check` No commit or merge was performed.

Implemented all seven blockers and left the PR unmerged/uncommitted for the system-managed publish step. Key changes include durable provider-operation generations, atomic failed reconciliation, exclusive resume leases/outbox settlement, bounded addressable model retries, strict credential-free DTO boundaries, transactional steering acknowledgements, and sensitive worktree rejection. Validation: - Runtime/recovery/Docker/security suites: 182/182 passed - Root typecheck and build: passed - Root and core lint: zero warnings/errors - `git diff --check`: passed - Suppression scan: clean New adversarial coverage is in [goalSessionSevenBlocker.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-08-31T18-03-26/packages/core/test/goalSessionSevenBlocker.test.ts). Current uncommitted base remains `9f5fa1f7f73d6e9b3c2160a5b2f907332f4c959a`; the automation can now publish the single new exact head.

Validation passed: - 169 runtime/recovery/Docker/security tests - Core typecheck and zero-warning lint - Root typecheck, zero-warning lint, and build - `git diff --check` - Suppression/Bloom scan The PR remains unmerged. Per instruction, changes are uncommitted for the system to publish; current HEAD remains `80591e6897799640b442b14901f686054b3bd3a6`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented all five runtime-foundation corrections: - Durable provider-visible monotonic fencing replaced the process-local `WeakMap` guard. - Recovery/event/state/error DTOs now use field-specific fail-closed validation and legacy-state scrubbing. - Model and operation identities are validated before any durable claim/history/provider activity. - Sensitive worktree and credential mount sources are centrally rejected while preserving `/var/www` and `/usr/src`. - SQLite model-history ordering now uses atomic per-scope sequence allocation with exact tombstones and concurrent-process coverage. Validation passed: - 150 accumulated goal-session/runtime/recovery tests - 41 Docker, mount, output, and security tests - New cross-process barrier and model-ordering matrix - Root and core typecheck, lint, and build - WeakMap/Bloom/suppression/ambiguous-sequence scans - `git diff --check` No commit or merge was performed. HEAD remains `4722b02052c27661c07110f07778a57bc7d96c9a`; the completed changes are left uncommitted for the system’s publication step.

Implemented the complete eight-item correction from exact head `8f047327dbca1608f63325e3a3583d365d31d505`. Highlights include durable replayable provider barriers, strict fail-closed state codecs, generic exception rebuilding, provider-specific credential ingress, ordered backpressured adapter output, invocation-time model settlement, supervised Codex App Server stdio initialization with exact `gpt-5.6-sol`, and bounded versioned recovery/usage accounting. Validation: - Focused runtime/security/crash matrix: 182/182 passed - Fast unit suite: 277/277 passed - UI suite: 465/465 passed - Full repository runner: 322/323 files passed - Sole full-suite exception: `test/llmMetrics.test.ts` timed out because Redis was unavailable at `127.0.0.1:6379` - Core lint with zero warnings: passed - Core typecheck: passed - Root/API lint and builds: passed - Shared/core/CLI builds: passed - CLI release package: passed - Release metadata and `git diff --check`: passed The PR remains unmerged. Per the harness instruction, I did not commit; therefore no new commit SHA exists yet. The unchanged worktree HEAD is `8f047327dbca1608f63325e3a3583d365d31d505`, and the system publisher will create the requested single commit.

Implemented the PR #2017 lint correction from exact head `613fff684ebe9ab5ae73116a5f553ae0b4bd36f9`. - Refactored cancellation, turn-stream processing, and durable relationship validation below complexity limits. - Extracted cohesive helpers so all seven requested files satisfy `max-lines`. - Preserved existing public exports and runtime behavior without ESLint disables or rule changes. - Kept changes scoped to goal-session/container runtime files. Validation passed: - Core lint with `--max-warnings 0`: zero warnings - Root, shared, core, and API builds - Root and API lint - Core typecheck - Focused goal-session/provider suites: 162 passed - Container/Docker/backpressure suites: 40 passed - `git diff --check` No commit was created, per instruction.

Implemented the six requested correction areas without committing or merging. Key outcomes: - Added durable, full-fence first-effect enforcement for every provider primitive, including cross-connection SQLite race coverage. - Removed pre-claim eager-open ingress and added the supervised container/duplex/App Server factory using `/workspace`. - Replaced the projected Codex protocol with generated 0.146 bindings, exact runtime validation, `workspace-write`, typed in-doubt handling, and live-binary contract tests. - Hardened exact next-turn model evidence, replay deduplication, recovery attempt binding, and completion withholding. - Made takeover safely settle cancelling/terminal states without replacing cancellation ownership. - Rejected orphan lease-expiry poison and enforced v2-only new recovery metadata ingress. Primary implementations include [providerFirstEffect.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-01T19-12-46/packages/core/src/agents/goalSession/providerFirstEffect.ts:8), [supervisedCodexOpenFactory.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-01T19-12-46/packages/core/src/agents/goalSession/supervisedCodexOpenFactory.ts:28), and [CodexAppServerOpen.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-01T19-12-46/packages/core/src/agents/goalSession/CodexAppServerOpen.ts:31).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented bounded slice 1 from exact unchanged head `af3102fe440a16fb6cae2ca09f4230dc67935331`. Key changes: - Added and exported production [SqliteGoalSessionRuntimePorts.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-02T05-56-35/packages/core/src/agents/goalSession/SqliteGoalSessionRuntimePorts.ts), sharing one SQLite authority for state, transitions, events, messages, model history, terminal commits, and provider first effects. - Redesigned first effects around synchronous explicit `{ completion }` handles. Transactions commit after primitive start and await completion outside; async callback escape is rejected. - Migrated open, turn/first-next, steer, pause, resume, model, reconcile, cancel, and Docker start paths. - Centralized `SAFE_ID` and secret-prefix checks in [safeIdentifier.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-02T05-56-35/packages/core/src/agents/goalSession/safeIdentifier.ts). - Added independent-connection cancellation/takeover races and adversarial zero-mutation tests in [goalSessionSliceOneCorrection.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-02T05-56-35/packages/core/test/goalSessionSliceOneCorrection.test.ts). Validation: - Focused goal-session/cross-SQLite suite: **177 passed, 0 failed** - Goal container hardening suite: **20 passed, 0 failed** - Core typecheck: passed - Core zero-warning lint: passed - Core build: passed - Root typecheck: passed - `git diff --check`: passed - Container tests emitted Node’s experimental module-mocking notice and existing `MaxListenersExceededWarning`s; no test failed. No commit, merge, or retarget was performed. Slice-2 response-loss/schema/pending-open behavior was not implemented.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the slice-1 re-audit correction without committing, merging, retargeting, or adding slice-2 work. Key changes: - Replaced the schema-owning SQLite runtime with mandatory injected [AuthoritativeGoalSessionRuntimePorts.ts](/tmp/git-processor/worktrees/integry/propr/pr-2017-followup-2026-09-02T06-45-09/packages/core/src/agents/goalSession/AuthoritativeGoalSessionRuntimePorts.ts). It creates no tables or connections. - Added durable per-stage identities for provider primitives, stream first-next, and Docker spawn. - Claims stages before effects, revalidates under the authoritative transaction, writes started receipts, and leaves duplicates durably in-doubt without restarting. - Added exact frozen WeakSet-branded handles with native promises and mandatory cleanup ownership. - Added cleanup for handle-validation, receipt-write, and commit failures, including cleanup failure and reentrancy handling. - Removed the redundant Codex transport-factory gate while preserving independent Docker and provider stages. - Added cross-connection global session-owner enforcement and nonconflicting test tables. - Preserved SAFE_ID and secret-prefix behavior. Validation: - Focused correction suite: 24 passed, 0 failed. - Goal-session/container real-path suite: 212 passed, 0 failed. - Core lint: 0 errors, 0 warnings. - Core typecheck: passed. - Core build: passed. - Root typecheck: passed. - `git diff --check`: passed. - Hosted CI for existing head `8f2e0481…`: 8 passed, 5 skipped. The new working tree cannot receive hosted CI until the system publishes its commit. - The broad container mock emitted 3 Node `MaxListenersExceededWarning` diagnostics; tests still passed. The PR remains unmerged and the working tree remains uncommitted for the automation to publish.

Implemented the exact-head correction without committing, merging, or retargeting. Key changes: - Added a production SQLite authoritative control domain and composition factory. - Consumes existing `goal_events`/`goal_messages`; runtime never creates schema. - Added a nonconflicting provider-effect migration with durable settled/recoverable/in-doubt states. - Removed `InMemoryGoalSessionPorts` from public package exports. - Enforced the exact three-stage allowlist at runtime and database ingress. - Replaced forgeable supervised-open plans with frozen, factory-issued plans. - Added exact pending-open process ownership, transfer, and idempotent cancellation. - Persisted terminal Codex response-loss state using an internal non-forgeable error brand. - Observes started completion rejection immediately, including cleanup-failure paths. - Added production two-connection SQLite/container/Supervisor acceptance coverage. Validation: - Focused recovery/race matrix: **50/50 passed** - Full goal-session/container suite: **224/224 passed** - Core lint: **passed, zero warnings/errors** - Core typecheck: **passed** - Core build: **passed** - Root typecheck: **passed** - `git diff --check`: **passed** - Exact head remains `4b605c203f5ab4e6eb688c461cc503c3feed3091` - No commit created; PR remains unmerged Hosted CI cannot run until the system publishes these uncommitted changes.
