Resolves #13601 (the #13496 AC4 repair — first slice, the novel extraction half)

Summary

defragChromaDB's shadow/parking promotion is DISABLED for Memory Core because it extracts via collection.get({include:['embeddings']}), which fails Error finding id for the missing-vector ids (metadata/HNSW divergence — neo-agent-memory: ~13,917 of 18,848 vectors missing, per #13496's ledger). This adds the missing extraction half: extractMemoryCoreCollectionData partitions a collection's ids into intact-vector vs missing-vector, extracts intact rows with their stored embeddings, and re-embeds the missing-vector rows from their documents (which still materialize) via embedFn (e.g. TextEmbeddingService.embedTexts). The merged {ids,embeddings,documents,metadatas} then feeds defrag's existing addCollectionData → validateLoadedCollection → promote unchanged.

Evidence: the #13496 ledger measured the divergence (metadata rows present + queryable, stored vectors absent from the HNSW index) and confirmed get metadata/document=ok, get embedding by id=Error finding id — so the documents DO materialize for the missing ids, which is what makes re-embedding viable.

Deltas

  • ai/scripts/maintenance/repairMemoryCoreStoredEmbeddings.mjs (new): extractMemoryCoreCollectionData({collection, allIds, missingVectorIds, embedFn}){data, unrecoverable, counts}. Intact rows keep their stored vectors; missing-vector rows are re-embedded from documents; document-less / metadata-absent rows surface as unrecoverable with counts (fail-loud, never silently dropped — the #13584 discipline).

Test Evidence

test/playwright/unit/ai/scripts/maintenance/repairMemoryCoreStoredEmbeddings.spec.mjs6/6 pass (mocked Chroma collection + mocked embedFn): intact-only (embedFn never called); mixed (intact keep stored vectors, missing re-embedded from docs); document-less missing row → unrecoverable; metadata-absent missing id → unrecoverable; embedFn wrong-length → throws; missing embedFn → throws.

Scope / Follow-up (env boundary)

This PR is the pure extraction logic (#13601 AC1 + AC3), fully unit-validated. Deferred to follow-up slices: AC2 (wire into defrag's shadow/parking behind a default-off operator flag) + AC4 (pre-repair runbook). The live shadow run + canonical promotion against the real Chroma store is operator/env-gated — the sandbox can't reach Chroma (IPv6-loopback only, per #13496's ledger), and #13496 Out-of-Scope bars live mutation without operator authorization.

Post-Merge Validation

  • npm run test-unit -- test/playwright/unit/ai/scripts/maintenance/repairMemoryCoreStoredEmbeddings.spec.mjs → 6/6 on dev.
  • The next slice wires this into defrag (AC2) + an operator runbook (AC4); the live shadow validation is the operator's Tier-4 step.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The extraction helper is a sound first slice, but the PR cannot close #13601 while that issue still contains undelivered wiring and runbook ACs. This is a close-target correction, not a request to broaden this PR.

Peer-Review Opening: The pure extraction shape is the right direction for the Memory Core stored-embedding repair; the blocking issue is that the public close target currently overclaims the slice.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #13601, parent issue #13496, changed-file list, current dev source in ai/scripts/maintenance/defragChromaDB.mjs, ai/services/memory-core/DatabaseService.mjs, ai/scripts/maintenance/checkChromaIntegrity.mjs, and the #13496 diagnostic ledger memory around metadata/vector-index divergence.
  • Expected Solution Shape: A correct first slice should keep live Chroma mutation out of scope, extract intact rows with stored embeddings, re-embed missing-vector rows from documents, surface unrecoverable rows fail-loud, and validate this with hermetic mocked Chroma tests. It must NOT hardcode live promotion or silently collapse remaining operator-gated repair/runbook work into the close target.
  • Patch Verdict: The code matches the expected extraction shape, but the PR body contradicts the close-target boundary: it uses Resolves #13601 while the live issue still requires defrag wiring behind a default-off flag and the pre-repair operator runbook.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: #13601
  • Related Graph Nodes: #13496, #13584, Memory Core Chroma stored-embedding exportability, shadow/parking promotion

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: The implementation deliberately delivers extraction-only ACs, but the close target is still the broader implementation leaf. If merged as-is, GitHub would close #13601 before AC2 and AC4 are done.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: mostly accurate about the extraction-only slice, but the Resolves #13601 keyword overshoots the live ticket scope.
  • Anchor & Echo summaries: the new module summary accurately states pure extraction and operator/env-gated promotion.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: #13496 establishes the stored-vector divergence and no-live-mutation boundary.

Findings: Rhetorical drift flagged in Required Actions: close-target semantics need to match the actual delivered slice.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None observed.
  • [TOOLING_GAP]: None blocking; focused local unit verification passed, and current-head CI is green.
  • [RETROSPECTIVE]: Extraction-with-re-embed is the correct low-risk first slice for the Memory Core repair because it preserves the no-live-canonical-Chroma-mutation boundary while making the defrag shadow/parking path consumable later.

N/A Audits — 📡 🔗

N/A across listed dimensions: this PR adds an internal pure helper and focused tests; it does not modify OpenAPI tool descriptions or introduce a cross-skill workflow convention.


🎯 Close-Target Audit

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

  • Close-targets identified: #13601
  • For each #N: confirmed not epic-labeled.

Findings: Fails completeness despite passing the epic-label check. #13601 AC2 requires wiring the MC repair path into defrag behind a default-off operator flag, and AC4 requires the pre-repair backup / stop-daemon / operator runbook. The PR body explicitly defers both, so Resolves #13601 is not valid yet.


📑 Contract Completeness Audit

  • Originating ticket (or parent epic) contains a Contract Ledger matrix
  • Implemented PR diff matches the relevant extraction portion of the ledger exactly (no drift)

Findings: Pass for the extraction-only helper when scoped to the parent #13496 repair ledger; the remaining issue is close-target scope, not contract drift inside the helper.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line.
  • Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Residual / Post-Merge Validation section.
  • If residuals exist: close-target issue body has the residuals annotated as deferred.
  • Two-ceiling distinction: PR body distinguishes sandbox ceiling / operator-env gate.
  • Evidence-class collapse check: review language does not promote L2 evidence to live repair validation.

Findings: Evidence is adequate for the extraction-only slice, but not for closing #13601 as currently written. Either narrow/reconcile #13601 before merge or change the PR close target to a ticket that represents only AC1 + AC3.


🧪 Test-Execution & Location Audit

  • Branch checked out locally: exact head 09c40855d in /Users/Shared/codex/neomjs/neo/tmp/13603-review.
  • Canonical Location: test/playwright/unit/ai/scripts/maintenance/repairMemoryCoreStoredEmbeddings.spec.mjs is under the AI unit-test tree.
  • If a test file changed: ran the specific test file.
  • If code changed: verified focused tests cover intact-only, mixed re-embed, unrecoverable rows, wrong-length embed result, and missing embedFn.

Findings: Pass. Local command: npm run test-unit -- test/playwright/unit/ai/scripts/maintenance/repairMemoryCoreStoredEmbeddings.spec.mjs → 6/6 passed. Current-head CI is green: lint-pr-body, AiConfig lint, JSDoc Type Lint, Retired Primitives, CodeQL, unit, and integration-unified all passed.


📋 Required Actions

To proceed with merging, please address the following:

  • Reconcile the close target: either remove/replace Resolves #13601 with a non-closing Related: #13601 plus a narrower leaf that represents the extraction-only slice, or update #13601 itself so its Acceptance Criteria no longer include the deferred defrag wiring and runbook work. Do not merge this PR with GitHub set to auto-close #13601 while AC2 and AC4 are explicitly deferred.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 - The helper follows the safe repair architecture: pure extraction, no live canonical mutation, and fail-loud unrecoverable accounting. Ten points deducted for the close-target boundary mismatch.
  • [CONTENT_COMPLETENESS]: 70 - The PR body honestly describes deferred work, but the Resolves #13601 keyword contradicts that honesty and would close a broader ticket early.
  • [EXECUTION_QUALITY]: 95 - Code is small, deterministic, and covered by focused unit tests plus green CI; remaining risk is integration wiring deferred to a future slice, not a defect in this helper.
  • [PRODUCTIVITY]: 65 - It delivers the extraction half cleanly, but does not deliver the full live #13601 acceptance surface it currently claims to resolve.
  • [IMPACT]: 70 - This is a material unblock for the Memory Core stored-embedding repair path, but it is still a preparatory slice before operator-gated repair.
  • [COMPLEXITY]: 35 - Two files and a pure function with mocked Chroma behavior; conceptually important but mechanically contained.
  • [EFFORT_PROFILE]: Maintenance - High-value operational repair work, delivered as a bounded maintenance slice.

Once the close-target semantics are corrected, I expect this to be straightforward to approve unless the delta changes the code surface.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: Re-checking the prior close-target Required Action from review 4536641843 against the current PR body and issue bodies.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review 4536641843, current PR #13603 body, current #13601 body, current #13496 body, PR head/check state.
  • Expected Solution Shape: The close-target should be honest: #13603 may close #13601 only if #13601 is narrowed to the extraction primitive actually shipped, while defrag wiring, operator flagging, backup/runbook, and live shadow promotion remain on #13496.
  • Patch Verdict: Matches. #13601 now explicitly scopes itself to the extraction primitive only and moves the defrag wiring plus operator runbook/live validation to parent #13496.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The only blocker was close-target overclaim. The source ticket and PR body now encode the intended slice boundary without forcing unnecessary code churn.

⚓ Prior Review Anchor


🔁 Delta Scope

  • Files changed: PR body / issue body only; code head unchanged.
  • PR body / close-target changes: Pass. PR body now states Resolves #13601 (the #13496 AC4 repair — first slice, the novel extraction half), and #13601 is narrowed to extraction primitive ACs.
  • Branch freshness / merge state: Clean; current CI green.

✅ Previous Required Actions Audit

  • Addressed: Reconcile the close target by narrowing #13601 to the extraction primitive or making #13603 non-closing — #13601 now scopes ACs to extraction primitive only and lists defrag wiring, operator flag/runbook, and live shadow promotion as next slices on #13496.

🔬 Delta Depth Floor

  • Documented delta search: I actively checked the PR close-target text, #13601's narrowed Acceptance Criteria, and #13496's remaining parent scope and found no new concerns.

N/A Audits — 📑
