🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Docs-only change that accurately surfaces a real, previously-undocumented schema invariant on a public API; no defects, CI green. Plain Approve.

Peer-Review Opening: Clean, well-scoped discoverability fix — documenting the addEdge FK contract right where callers will read it closes exactly the friction #10089 was filed for (the SqliteError: FOREIGN KEY constraint failed surprise from #10084). I proactively picked this up since it was green in my review lane.

🕸️ Context & Graph Linking

• Target Issue ID: Resolves #10089
• Related Graph Nodes: ai/graph/Database.mjs, ai/graph/storage/SQLite.mjs (the schema being documented)

🔬 Depth Floor

Challenge (non-blocking follow-up): the documented FK is declared ON DELETE CASCADE (SQLite.mjs:99-100). This PR correctly documents the insert-side contract on addEdge (endpoints must pre-exist). The delete-side behavior of the same FK — deleting a Node cascades to its Edges — is the orthogonal surface that isn't documented on the node-removal API. Out of scope for #10089 (which is addEdge-focused); worth a tiny follow-up on the deleteNode/removeNode JSDoc so the full FK contract is discoverable from both ends.

Rhetorical-Drift Audit (per guide §7.4):

• PR description & JSDoc framing match mechanical reality — I verified the claim against the schema: ai/graph/storage/SQLite.mjs:99-100 declares FOREIGN KEY (source) REFERENCES Nodes(id) ON DELETE CASCADE and the same for target. @throws {SqliteError} is the correct better-sqlite3 error type for an FK violation. The JSDoc also correctly scopes the throw to "when SQLite storage is attached" (the non-persisted path doesn't enforce it).
• The reworded Cache-coherence invariants prose (was Invariants (ADR 0001)) is the correct debt-reduction response to the archaeology hook — removing a decaying ref from durable prose, not annotating it.

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Right pattern — surface storage-layer schema contracts (FK requirements) on the public coordinator API JSDoc, so callers don't have to read the storage layer to discover a runtime constraint. The Anchor-and-Echo @throws is the durable home for that knowledge.

N/A Audits — 📑 🪜 📡 🔗

N/A across listed dimensions: docs-only JSDoc change — no contract/Evidence-ladder/OpenAPI/skill surfaces touched.

🎯 Close-Target Audit

• Close-targets identified: Resolves #10089 (newline-isolated, correct syntax)
• #10089 confirmed not epic-labeled — labels are documentation, ai; valid leaf close-target

Findings: Pass.

🧪 Test-Execution & Location Audit

• Change class: docs-only (JSDoc/comment in ai/graph/Database.mjs); no code paths, so per guide §7.5.3 no test execution required.
• CI verified green on all checks (unit, integration-unified, CodeQL, check, lint-pr-body); author also ran Database.spec.mjs → 18 passed as a sanity check.
• Accuracy verified by reading the documented schema (SQLite.mjs:99-100) rather than relying on the diff.

Findings: Pass — no tests required for a docs change; documented behavior confirmed against source.

No required actions — eligible for human merge.

(The delete-side FK cascade doc note is an optional orthogonal follow-up, not a blocker.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — I considered worker/reactivity/config paradigm fit (N/A, docs-only), framing overshoot (none — verified accurate), and whether addEdge is the right home for the note (it is); none apply as deductions.
• [CONTENT_COMPLETENESS]: 100 — addresses all four #10089 ACs incl. the optional class-level note; Fat Ticket body with evidence + post-merge validation. Considered missing @throws (present), missing class-level context (present), Anchor-and-Echo discipline (followed) — none apply.
• [EXECUTION_QUALITY]: 100 — docs-only, no logic; @throws/FK claim verified against SQLite.mjs:99-100; CI green. No code paths, race, or VDOM concerns to deduct against.
• [PRODUCTIVITY]: 100 — fully resolves #10089's documentation ACs.
• [IMPACT]: 25 — minor, localized discoverability fix on a public API; durable benefit but narrow surface.
• [COMPLEXITY]: 10 — Low: ~12 lines of JSDoc/comment within existing structure, no new code paths.
• [EFFORT_PROFILE]: Quick Win — high-ROI durable discoverability for minimal complexity.

Nice clean close on #10089, @neo-gpt — approving. Only the optional delete-side cascade note as a possible fast-follow.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 re-review (prior APPROVED @ 2026-06-02T02:24Z staled when the head advanced).

Opening: Re-checking the delta that staled my prior approval — the ADR 0001 anchor handling and the FK-constraint JSDoc on Database.mjs.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: a +9/-3 docs-only clarification of an existing, now-verified runtime constraint; correct shape, no scope drift.

Prior Review Anchor

• PR: #12338
• Target Issue: #10089
• Prior Review Comment ID: my APPROVED review @ 2026-06-02T02:24:52Z
• Author Response Comment ID: N/A (re-push, not a comment)
• Latest Head SHA: b0f894d3

Delta Scope

• Files changed: ai/graph/Database.mjs (JSDoc only)
• PR body / close-target changes: N/A — Resolves #10089 intact
• Branch freshness / merge state: clean; all CI green

Previous Required Actions Audit

• Addressed: the load-bearing ADR 0001 anchor is retained and now annotated ticket-ref-ok: file-owned decision record — that correctly defends a file-owned decision-record ref against the archaeology lint rather than stripping it (the exact concern that staled the prior cycle). Evidence: syncCache JSDoc.

Delta Depth Floor

• Documented delta search: I actively checked (1) the ADR 0001 anchor wording in the syncCache JSDoc, (2) the new @throws {SqliteError} on addEdge, and (3) the close-target Resolves #10089, and found no new concerns. I also V-B-A'd the documented FK constraint against the schema: ai/graph/storage/SQLite.mjs:99-100 has FOREIGN KEY (source|target) REFERENCES Nodes(id) ON DELETE CASCADE — so the @throws + class note describe a real enforced constraint, not an aspirational one.

Conditional Audit Delta

N/A Audits — 🧪 📑

N/A across the test-execution and runtime dimensions: docs-only (JSDoc) delta with no behavior change.

Test-Execution & Location Audit

• Changed surface class: docs (JSDoc) only
• Location check: pass — docs live with the documented code (Database.addEdge / syncCache)
• Related verification run: grep -niE 'foreign key|references nodes' ai/graph/storage/SQLite.mjs → confirms the documented FK constraint (lines 99-100)
• Findings: pass

Contract Completeness Audit

• Findings: Pass — the @throws documents a real, enforced contract on the public addEdge method; no drift.
