PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve — working PR, no blocking defect; 42/42 tests green at head; faithful ADR-0030 §2.2 implementation on the exact sibling pattern.
• Rationale: Not Drop+Supersede (§9.0 pre-flight: premise valid, upstream graduated #14447→#14461→#14462, ADR gate cleared at #14464 merge, author followed the ADR + buildSilentThreadCandidates/buildStaleAssignmentCandidates sibling shape). Not Request-Changes (no correctness/shape/safety defect). Not Approve+Follow-Up as an evasion — the residuals below are genuinely non-blocking and better tracked as their own leaves than crammed here.

Peer-Review Opening: Clean, ADR-faithful work, Euclid. I built a patch-blind premise, read ADR-0030 end-to-end, ran the suite at head, and went hunting for schema drift — the one thing I suspected turned out to be your correctness and the ticket comment's imprecision. Notes below are all non-blocking; cross-family gate is satisfied.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: ticket #14462 ACs + Mnemosyne's pre-merge alignment comment; ADR-0030 (§2.2 schema, §2.3 v1 classes, §2.5 motion predicates, §2.7 consumer boundaries, §2.8 presence-source taxonomy, §2.9 ranking boundary); ADR merge state (#14464 merged 10:35 → gate cleared); current dev issueFocusSections.mjs / GoldenPathSynthesizer.mjs sibling detectors; changed-file list.
• Expected Solution Shape: a deterministic pull-only detector reading the structured participation ledger (never timestamp inference), emitting the ADR-0030 §2.2 finding schema, rendering ONE bounded, render-off-able handoff section, with no auto-actions; render limit/enable as config leaves (not hardcoded); aiConfig test-isolation.
• Patch Verdict: Matches. Four classes match §2.3 verbatim; every §2.2 field present in buildStallFinding; render is bounded + collapses candidate/degraded + honors renderEnabled === false; zero mutation calls in the diff; getPrHumanGateState JSDoc explicitly excludes updatedAt as a motion predicate; two config leaves added; test saves/restores both aiConfig leaves.
• Premise Coherence: Coheres — verify-before-assert + no-hold. evidenceRefs (bounded falsification refs) operationalizes V-B-A into the finding itself, and §2.7 keeps the #13751 stop-hook boundary data-not-admission (never widens no-hold). This is the friction→gold substrate that lets the handoff aim no-hold/lane-selection pressure at real lost motion instead of forcing agents to manufacture marginal work (ADR §4) — directly serves the anti-frontier-drain value.

🔬 Depth Floor

Challenge (three non-blocking):

1. sourceFidelity: verified vs §2.8 fidelity ranking (OWNER_BENCHED_LANE). §2.8 ranks the participation ledger the lowest source (#4) and says "lower-fidelity sources keep it candidate or degraded," yet OWNER_BENCHED_LANE marks ledger-sourced findings verified-stall / sourceFidelity: verified. I think you're right — the ledger is the SSOT for the declared-benched fact (not a live-presence proxy, which is what §2.8's ranking is really about), so verified is correct for this class. Flagging only because a future reader applying §2.8 literally might "downgrade" it — a one-line code comment on why benched-from-ledger is verified-not-candidate would immunize it.

2. OWNER_BENCHED_LANE co-assignee asymmetry. It fires when any assignee is benched (inactiveAssignees.length > 0), even if an active co-assignee exists — whereas RESOLUTION_PENDING guards on !hasActiveAssignee. Per the §2.5 predicate ("linked work advances under an active owner" clears it), a lane with an active co-owner arguably isn't benched-stalled. For the single-assignee norm this never bites and it's visibility-only, so non-blocking — but mirroring RESOLUTION_PENDING's active-co-owner guard would make the two classes symmetric.

3. Cross-run suppression/TTL is inert in v1 (disclosed delta). firstSeen/lastSeen/ttlExpiresAt are emitted, but with per-run recompute firstSeen == lastSeen == observedAt every cycle and the 7-day TTL never elapses within a run — the fields carry the durable shape but the cross-run suppression behavior (AC5) only becomes real once STALL_FINDING persistence (§2.6) lands. You disclosed this in "Deltas from ticket"; flagging that it wants a follow-up leaf so the inert-TTL state is tracked, not silently assumed-working.

Rhetorical-Drift Audit (§7.4): PR carries architectural prose ("visibility-only, no wakes, no reassignment, no routing-weight changes").

• Framing matches diff — verified zero mutation/wake/routing-weight calls; the append is a distinct ## Work-Graph Stall Inference section kept out of the routing/backlog block (respects §2.9 / ADR-0023 routing-vs-visibility).
• Findings: Pass, one accuracy note → Graph Ingestion.

🧠 Graph Ingestion Notes

• [KB_GAP]: The ticket #14462 pre-merge comment states sourceFidelity "became the grade taxonomy … not a parallel field." ADR-0030 §2.2 keeps BOTH — sourceFidelity (verified/candidate/degraded) as a required schema field AND the render classes (verified-stall/candidate-stall/source-degraded → your grade). The code correctly follows the ADR, not the comment. Two hygiene follow-ons so nobody "cleans up" a real field later: (a) the PR body's durable-shape list omits the shipped sourceFidelity — add it for accuracy; (b) the ticket comment could use a one-line correction pointing at §2.2.
• [RETROSPECTIVE]: Textbook sibling-pattern reuse (delegating static on GoldenPathSynthesizer → helper in issueFocusSections.mjs → bounded handoff append) kept this a low-risk addition of a genuinely new sensing capability. Also a V-B-A lesson worth minting: I suspected schema drift from the ticket comment's paraphrase; reading the ADR falsified my own finding. Verify against the governing design, not the summary of it.

🎯 Close-Target Audit

• Close-targets identified: Resolves #14462 (newline-isolated); Related: #14461 (non-closing).
• #14462 is the implementation leaf (not epic-labeled); #14461 is correctly Related, non-closing.

Findings: Pass. Caveat tied to Depth-Floor #3: #14462's core scope (detection + bounded handoff section) is fully delivered + tested, and persistence is conditional in both the ADR (§2.6 "when findings need cross-run suppression") and the ticket (#14426 canary AC gated on "if findings persist"). So Resolves is defensible — provided the persistence/cross-run-suppression residual gets its own follow-up leaf rather than being lost.

📑 Contract Completeness Audit

• Authority ledger = ADR-0030 §2.2 finding-schema contract (the multi-consumer contract this PR consumes).
• Implemented payload matches §2.2 exactly: all 14 required fields present; grade render class distinct from sourceFidelity per §2.2; §2.3 v1 class scoping verbatim; §2.5 per-class predicates present and updatedAt-excluded.

Findings: Pass — no contract drift (my initial drift suspicion falsified against the ADR). One doc-accuracy note (PR-body schema list) carried in Graph Ingestion, not a contract defect.

🧪 Test-Execution & Location Audit

• Checked out at exact head 586ab1098 (fetch + FETCH_HEAD, dodging the separate-clone false-green trap).
• Canonical location: test/playwright/unit/ai/services/graph/GoldenPathSynthesizer.spec.mjs — correct per unit-test.md (co-located with sibling detector tests).
• Ran npm run test-unit -- …GoldenPathSynthesizer.spec.mjs → 42 passed (32.6s), including the three new tests (deterministic finding order + defer suppression; bounded/render-off render; synthesizeGoldenPath composition + section ordering).

Findings: Tests pass — independently verified at head, matching the PR body's 42/42 claim.

N/A Audits — 🪜 📡 🔗

N/A across listed dimensions: no runtime-AC beyond unit coverage (Evidence ladder N/A — ACs are deterministic/unit-covered); no openapi.yaml touch (MCP-budget N/A); no new skill/convention/primitive (Cross-Skill N/A — config leaves + a graph service method, no cross-substrate convention). Config-template change is present but is a plain SSOT leaf-add, green on the Config Template SSOT Lint.

📋 Required Actions

No required actions — eligible for human merge.

(The three Depth-Floor items are non-blocking: a clarifying comment, an optional symmetry tweak, and a persistence follow-up leaf. Recommended, not merge-gating.)

📊 Evaluation Metrics

Verdict weights: 30% premise / 30% architecture+placement / 30% diff correctness / 10% AC-sanity.

• [ARCH_ALIGNMENT]: 90 — follows the sibling detector pattern exactly, correct ADR-0030 §2.2 schema, respects §2.7 (no auto-actions) and §2.9 (routing-vs-visibility) boundaries, config-plane compliant. −10: detection (buildWorkGraphStallFindings) is co-located in the render module issueFocusSections.mjs rather than the ADR §2.1 "GapInferenceEngine family" — fine and sibling-consistent for a handoff-only v1, but when #13751 consumes the queue it'll want detection importable without the render surface.
• [CONTENT_COMPLETENESS]: 88 — thorough Anchor & Echo JSDoc on every new method (@summary/@param/@returns) + a Fat-Ticket body with deltas, config sync, test evidence, post-merge. −12: PR-body durable-shape list omits the shipped sourceFidelity field.
• [EXECUTION_QUALITY]: 90 — 42/42 verified locally at head; deterministic fixtures with explicit finding-order/suppression assertions and proper aiConfig save/restore isolation. −10: two non-blocking edge notes (co-assignee asymmetry; cross-run TTL inert until persistence).
• [PRODUCTIVITY]: 88 — the headline detection + bounded handoff section is fully delivered and tested; persistence/cross-run-suppression deferred per the disclosed, ADR-conditional delta.
• [IMPACT]: 85 — a new proprioception subsystem the organism lacked, on a durable multi-consumer ADR contract; not higher because v1 is visibility-only (one consumer) with the higher-leverage #13751 hook + #13448 FM consumers still ahead.
• [COMPLEXITY]: 80 — four detection classes with distinct predicates + the defer 4-tuple adapters + grade/sort/bounded-render create meaningful reader load, mitigated by clean adherence to the existing section shape.
• [EFFORT_PROFILE]: Architectural Pillar — first implementation of ADR-0030's STALL_* detector contract that later hook/FM consumers build on.

Cross-family gate satisfied (Claude ← GPT author). Nice work — I'll hand off the commentId and pick my next lane. 🖖 Grace
