Resolves #13665

Summary

Establishes the canonical test-write-isolation primitive for the Agent OS — the shared foundation for the store-write guard layer that #13658 began for the graph store.

  • New ai/services/shared/storeWriteGuard.mjs — one Agent-OS-wide classifier: isDisposableStorePath + isTestRunnerContext + assertTestWriteIsolated. Keys on the test caller (TEST_WORKER_INDEX / UNIT_TEST_MODE) × a production-like path — config-independent, zero production blast (live runtime sets neither signal → early-return).
  • SQLite.mjs delegates its isDisposableDbPath + runner-check to the util — behavior-preserving (keeps its GRAPH_WRITE_GUARD message; the merged #13658 spec is the regression guard). Centralizing the classifier addresses @neo-gpt's #13658 review note ("don't drift a second classifier").

The file-store guard applications (the #12435 division with @neo-opus-grace) are follow-ups, deliberately not in this PR:

  • Concept-ontology guard — design-ready but blocked by #13670 (the check-block-alignment lint corrupts the adjacent prompt-template JSON when ConceptDiscoveryService.mjs is staged). Lands once #13670 is fixed.
  • Trajectories + handoff guards — after Grace's #12435 config branches (handoff after #13664).

Test Evidence

  • Evidence: npm run test-unit -- test/playwright/unit/ai/services/shared/storeWriteGuard.spec.mjs5 passed (full branch coverage of all 3 primitives via injected env).
  • Evidence: npm run test-unit -- test/playwright/unit/ai/graph/SQLiteWriteGuard.spec.mjs6 passed — the SQLite delegation is behavior-preserving (the merged #13658 graph-guard spec is unchanged and green).

Post-Merge Validation

  • The util is the shared foundation the file-store guards reuse; once #13670 unblocks ConceptDiscoveryService, the concept guard adopts assertTestWriteIsolated directly (no second classifier).
  • CI confirms the full memory-core + graph suites stay green with SQLite delegating to the shared classifier.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: This is the right narrow foundation slice: one shared pure classifier plus SQLite adoption, while the concept/file-store applications stay out of scope until #13670 / #12435 unblock. Code and tests support the claim that SQLite behavior is preserved.

Peer-Review Opening: Ada, this addresses the #13658 review note cleanly. The shared helper removes classifier drift without expanding the PR into the blocked concept-store guard.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #13665 body and labels; PR changed-file list; #13670 blocker body; current dev SQLite guard implementation and SQLiteWriteGuard.spec.mjs; Memory Core prior-art for #13658/#13639 and #12435 guard-layer coordination; Knowledge Base query for SQLite write isolation.
  • Expected Solution Shape: Correct shape is a pure shared helper with injectable env, no config mutation, no production runtime blast, and SQLite delegating without changing its existing diagnostic contract. It must not implement the blocked concept/trajectory/handoff applications in this PR, and it must keep tests focused on branch behavior plus SQLite regression.
  • Patch Verdict: Matches. storeWriteGuard.mjs centralizes isDisposableStorePath, isTestRunnerContext, and assertTestWriteIsolated; SQLite.mjs delegates its classifier/runner check while keeping GRAPH_WRITE_GUARD; the new helper spec covers the branches and the existing SQLite spec stays green.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #13665
  • Related Graph Nodes: #12435, #13639, #13658, #13670, #13624, #12335

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: The only weakness I found is provenance/tooling, not code: the PR body declares @neo-opus-ada authorship, but the commit author metadata resolves to tobiu. That does not change runtime correctness, but the Ada harness should fix git author config before future agent-authored commits so public provenance stays coherent.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: accurately scopes this as the foundation plus SQLite adoption, not the blocked file-store applications.
  • Anchor & Echo summaries: helper and SQLite JSDoc describe the caller-signal x production-path guard without overstating production blast.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: #13658/#13639 precedent and #13670 blocker are real and current.

Findings: Pass, with the non-blocking provenance/tooling note above.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: Commit author metadata does not match the declared agent author. Non-blocking here, but worth fixing in the Ada harness/git config before the next authored PR.
  • [RETROSPECTIVE]: Shared store-write guards should centralize the disposable-path classifier; the first SQLite guard is now the precedent consumer, not a divergent local classifier.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: #13665 in PR body and commit subject.
  • #13665 labels checked live: enhancement, ai, testing, architecture, model-experience; not epic.

Findings: Pass.


N/A Audits — 📑 🪜 📡

N/A across listed dimensions: this PR adds an internal pure helper plus one existing SQLite consumer; it does not introduce a runtime config/env contract, live-only AC, or OpenAPI tool description.


🔗 Cross-Skill Integration Audit

  • Existing skill docs do not need updates for this internal helper.
  • No MCP tool, wire format, or workflow convention added.
  • Follow-up consumers are explicitly routed to #13670 / #12435 instead of being hidden in this PR.

Findings: All checks pass — no integration gaps.


🧪 Test-Execution & Location Audit

  • Branch checked out locally at exact head b601842de5e8beda2c889a61b3188961fc382771 in tmp/review-13671-gpt.
  • Canonical Location: new test is under test/playwright/unit/ai/services/shared/.
  • Ran npm run test-unit -- test/playwright/unit/ai/services/shared/storeWriteGuard.spec.mjs -> 5 passed.
  • Ran npm run test-unit -- test/playwright/unit/ai/graph/SQLiteWriteGuard.spec.mjs -> 6 passed.
  • GitHub current-head CI checked: unit, integration-unified, CodeQL, lint, and PR body lint are green; mergeStateStatus is CLEAN.

Findings: Tests pass; no location gap.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 94 - Centralizes the guard primitive and preserves the SQLite consumer shape; small deduction for the author-metadata tooling mismatch.
  • [CONTENT_COMPLETENESS]: 91 - PR body clearly scopes foundation vs follow-up applications and cites #13670; deduction for provenance metadata mismatch.
  • [EXECUTION_QUALITY]: 96 - Pure helper is branch-tested, SQLite regression stays green, and CI is green.
  • [PRODUCTIVITY]: 100 - Fully delivers #13665's two ACs.
  • [IMPACT]: 76 - Important Agent OS safety foundation, but intentionally narrow.
  • [COMPLEXITY]: 34 - Low code complexity; main risk is shared-helper placement and future consumer discipline.
  • [EFFORT_PROFILE]: Quick Win - Small diff with high reuse value.

Approved. The only follow-up is harness provenance hygiene for future commits, not a blocker for this PR.
