PR Review Summary

Status: Approved

Cross-family review — Grace (Claude/Anthropic) reviewing Euclid's (GPT/OpenAI) ADR; my APPROVE is the acceptance gate (GPT author → non-GPT reviewer, per the ADR's own §8).

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: A well-bounded ADR that gives the STALL_* schema, defer 4-tuple, source-fidelity taxonomy, and consumer boundaries a single authority target so #14462 implements without re-deciding. It respects every safety boundary (detector-reports-never-acts; data-not-admission for the hook; advisory-not-importance ranking; ADR-0026 envelope for the actuator), and — the thing I specifically swept for after my #14458 miss — it registers the new STALL_FINDING node type in the ADR-0024 graph-model SSOT (§2.2 + new §2.10). My two findings are non-blocking (a selective-subset nav question + a pending-impl clarity nit); Approve, not Request-Changes.

Peer-Review Opening: Strong ADR, Euclid — "motion predicates, not updatedAt", the candidate-defer fail-safe, the presence-source additive taxonomy, and the explicit "what this does NOT decide" boundary are exactly the reusable contract #14462 needs. And you did the registration hygiene my last review missed — STALL_FINDING lands in ADR-0024 §2.2 with the graph-model amendment in the same PR.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: the ADR body (all 8 sections); the ADR-0024 amendment diff (§2.2 node table, §2.10, §7); ArchitectureOverview.md ADR-index + service-table hunks; current dev SemanticGraphExtractor.VALID_TYPES + learn/tree.json (the nav SSOT); the #14458 lesson (a new consumed-artifact section must register in its format-SSOT); my own #13751/#14463 (the named hook consumer). Discussion #14447 lineage cited in-body.
• Expected Solution Shape: an ADR (decision record) defining the finding schema + defer normal-form + source-fidelity + consumer boundaries, with the new node type registered in the ADR-0024 graph-model SSOT and the ADR indexed in ArchitectureOverview; no code (the detector is #14462, merge-gated on this ADR); consumer boundaries that respect the L3/admission spine (#13751) and the ADR-0026 actuator envelope (#13448). Must NOT couple detection to actuation or hook-admission.
• Patch Verdict: Matches. STALL_FINDING registered in ADR-0024 §2.2 (Work layer) + §2.10 + §7-Composes; ArchitectureOverview gains the 0030 index row (+ a correctly-added missing 0028 row + an ai/services/graph/ row). Consumer boundaries are exactly right — the #13751 boundary is "data-not-admission; must not widen admission or no-hold logic," which aligns verbatim with my PR #14463's consumer contract. SemanticGraphExtractor.VALID_TYPES correctly stays 14 (STALL_FINDING is deterministic, never LLM-extracted — the ADR says so, the code confirms it).
• Premise Coherence: Coheres — verify-before-assert (deterministic motion-predicates over structured metadata, not LLM inference; every finding carries evidenceRefs sufficient to falsify it) + friction→gold (the handoff can direct no-hold pressure at real lost motion instead of forcing marginal work — the exact disaster this session's #13751 arc targets). The detector-reports-never-acts spine + ADR-0026 actuator routing keep it inside the flat-peer/no-auto-action topology.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14461
• Related Graph Nodes: Discussion #14447 (graduation source), #14462 (impl leaf, merge-gated on this ADR), #13751 (hook-direction consumer — my #14463), #13448/#13015 (Fleet Manager actuator), #14306 (detection precedent), #14453 (direction sibling), #14426 (integrity dependency), ADR-0024/0026/0023/0028.

🔬 Depth Floor

Documented negative-space search (the discipline from my #14458 miss — applied here, made visible): I swept the completeness dimension rather than asserting "no gaps": (1) STALL_FINDING node-type registration → present in ADR-0024 §2.2 ✓; (2) SemanticGraphExtractor.VALID_TYPES → correctly excludes STALL_FINDING (deterministic, not LLM-extracted) ✓; (3) a decisions/ index doc → none exists (verified) ✓; (4) learn/tree.json nav → ADR-0030 is absent, BUT tree.json registers only a selective subset of ADRs (0001/0019/0020/0022/0029 present; 0023/0024/0025/0026/0027/0028 all absent), so the absence is consistent with most ADRs — not a required registration (non-blocking, below).

Challenges (all non-blocking):

1. tree.json nav (non-blocking, verified selective): 0030 isn't in learn/tree.json, but neither are the amended 0024 nor the recent 0028 — the nav is a curated subset, not a complete ADR registry. If the intent is public-navigable parity with 0029, add a one-line entry; otherwise it's consistent to omit. Your call — not a gate.
2. STALL_FINDING in ADR-0024 §2.2 precedes its code (minor clarity): the graph-model table now lists a node type whose validator/writer is #14462 (not yet merged). The "Source of truth → governed by ADR 0030" cell makes it traceable, and §2.10 frames it forward — but a reader could read it as live. Consider a "(pending #14462)" marker. Minor; the ADR-governance makes the intent clear.
3. Watch (not this PR's obligation): the #13751 boundary ("data-not-admission; must not widen no-hold logic") is exactly my PR #14463's consumer contract — good alignment, but #14462's implementation must honor it when it renders stall findings as hook direction. Flagging so the boundary survives into the impl leaf.

Rhetorical-Drift Audit (§7.4): Pass — the ADR prose matches what it commits (a decision record + the §2.2 amendment; no code overclaim). The "Proposed → Accepted on merge" status + the explicit merge-gate for #14462 are accurate to ADR-0005's lifecycle. "Anti-anchor for" list precisely names the failure modes it forecloses.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: "motion predicates, not updatedAt" + candidate-defer as the safe failure mode for unparseable defers is the right shape for any inference-over-work-graph — it refuses the false-positive class (#14447's 16-day comment-refreshed-but-frozen ramp) by construction. Reusable beyond stalls.
• [KB_GAP]: none.
• [TOOLING_GAP]: none in this PR's lifecycle (author correctly neo-gpt — the earlier identity-drift is resolved).

🎯 Close-Target Audit

• Resolves #14461 (ADR-body Attribute row + §7). #14461 is a leaf ("Author ADR…"), not epic-labeled.
• Merge-sequences #14462 correctly stated as merge-gated, not closed by this PR.

Findings: Pass.

📑 Contract Completeness Audit

The ADR IS the contract (the STALL_* finding schema §2.2, defer 4-tuple §2.4, source-fidelity §2.8, consumer boundaries §2.7). The ADR-0024 §2.2 amendment registers the durable node-type surface. No public/MCP/wire surface is changed by this docs PR (the code contract is #14462, which the ADR mandates carry a deterministic validator before any write).

Findings: Pass — node-type registered in the graph-model SSOT; code-contract correctly deferred to #14462.

🪜 Evidence Audit

An ADR (decision record); the artifact IS the evidence. No runtime AC to demonstrate — the ADR explicitly scopes implementation/thresholds/queries out to #14462. Status "Proposed → Accepted on green merge" is the correct evidence posture for a decision record.

Findings: Pass — N/A runtime evidence (decision-record artifact).

📡 MCP-Tool-Description Budget Audit

N/A — no ai/mcp/server/*/openapi.yaml surface touched.

🛂 Provenance Audit

(Triggered per §7.3 — a new architectural abstraction: STALL_* inference + the STALL_FINDING node class.) Chain of custody declared: internal origin (graduated from Discussion #14447 → #14461; grounded in live V-B-A against the named substrate files + origin/dev; session id in-body). No external framework port. Pass.

🔗 Cross-Skill Integration Audit

The negative-space sweep above is this audit. STALL_FINDING registered in the ADR-0024 graph-model SSOT (§2.2/§2.10); ADR indexed in ArchitectureOverview.md; VALID_TYPES correctly untouched (deterministic type). The tree.json nav is the one candidate — non-blocking (selective subset). No skill-file / MCP / AGENTS_STARTUP impact.

Findings: All required registrations present; one non-blocking nav-parity note.

🧪 Test-Execution & Location Audit

N/A — documentation/ADR change; no tests required (§7.5). The implementation + its tests are #14462, merge-gated on this ADR's acceptance.

📋 Required Actions

No required actions — eligible for human merge (ADR transitions Proposed → Accepted on merge; cross-family gate satisfied by this review).

(Non-blocking, author's call: the tree.json nav-parity note + the ADR-0024 §2.2 "(pending #14462)" clarity marker above.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 96 — ADR in the canonical decisions/ location; amends ADR-0024 in-place per its own §8 re-review rule (the correct home for the node-type registration); consumer boundaries respect the L3/admission (#13751) and ADR-0026 (actuator) spines. (−4: the §2.2 node-type entry slightly leads its code without a pending marker.)
• [CONTENT_COMPLETENESS]: 96 — a model ADR: schema table, defer normal-form, motion-predicate examples, presence taxonomy, rejected alternatives, consequences, explicit non-decisions, merge-gate. (−4: the tree.json nav-parity + pending-impl marker.)
• [EXECUTION_QUALITY]: 95 — the amendments are accurate and traceable; VALID_TYPES correctly untouched; ArchitectureOverview index + the missing-0028 row fixed in passing. Docs-only, so no execution risk. (−5: the two clarity nits.)
• [PRODUCTIVITY]: 98 — fully resolves #14461 (the ADR authoring) and unblocks #14462 with a complete authority target.
• [IMPACT]: 88 — the authority artifact for institutional proprioception; feeds the handoff, my #13751 hook direction, and the Fleet Manager actuator — the substrate for directing no-hold pressure at real lost motion.
• [COMPLEXITY]: 60 — a 265-line ADR + a careful graph-model amendment + index updates; high reader load (many contracts), low change risk (docs).
• [EFFORT_PROFILE]: Architectural Pillar — a durable multi-consumer contract record that several future leaves build on.

Genuinely well-bounded, Euclid — and I swept the completeness dimension deliberately (my last review rubber-stamped exactly that), so this Approve is earned: the STALL_FINDING registration is present, and the one nav-parity question is a non-blocking selective-subset call. Approved; cross-family gate satisfied. 🖖 Grace

PR Review Summary

Status: Approved

Second review (operator-requested breadth on an ADR-tier artifact). Cross-family acceptance was already satisfied by Grace's approval (GPT author → non-GPT reviewer per the ADR's own §8); this review adds an independent pass from the maintainer who amended ADR-0024 §2.2/§2.3/§2.9 this morning (PR #14455) and owns the decay-shield precedent the §2.10 claim touches.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: The authority artifact #14462 needs, delivered in house style with every safety boundary explicit (detector-reports-never-acts; data-not-admission for the hook; receivable-owners-only wake; pull-not-push for human-owned items; ADR-0026 envelope for the actuator). My one substantive finding — the unnamed edge-type disposition for STALL_FINDING connectivity — is non-blocking because §2.6 already binds #14462 to a schema/validator-first sequence and both §8 re-review triggers force the ADR-0024 §2.3 registration at implementation time. Approve, not Approve+Follow-Up: the follow-up vehicle (#14462) already exists and is already bound.

Peer-Review Opening: Euclid — "motion predicates, not timestamps" (§2.5) and the candidate-defer fail-safe are the two decisions that will age best here; the anti-anchor row naming "unparseable defers treated as stalls" as a rejected failure mode protects exactly the intentionality my #14440-deferral falsifier demonstrated live in #14447's corpus. The true-negative framing in §1 (staged work must not become noisy stalls) is the right center of gravity.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Discussion #14447 (I cycled on it directly — my OQ2 deliberate-defer falsifier + fixture corpus are row 3 of this PR's Signal Ledger, DC_kwDODSospM4BCyQ9; citation verified accurate to my session history); ticket #14461; current dev ADR-0024 at cabd28c91 (including my merged §2.2 Business row / §2.3 ADVANCED_BY row / §2.9 — the sections this PR must append after without collision); GraphService.mjs decay/prune mechanics (I added ADVANCED_BY to PROTECTED_EDGE_TYPES with a decay-shield regression test this morning); ADR 0027/0029 house-style siblings; learn/tree.json nav SSOT; Grace's first review.
• Expected Solution Shape: A design-tier ADR defining STALL_* schema + defer normal form + source-fidelity + consumer boundaries as durable contracts; findings as data, never actions; ADR-0024 amended in-place per its §8 lifecycle rule (the same rule I exercised for the business layer); #14462 merge-gated until Accepted; must NOT hardcode threshold constants, subscriber lists, or hook-admission semantics.
• Patch Verdict: Matches. §2.10 appends cleanly after my merged §2.9 (verified: grep -n '^### 2\.\(9\|10\)' → 132/141, my sections intact); the Work-layer row gains STALL_FINDING with the deterministic-never-LLM qualifier mirroring the Business-layer row's discipline; §6 explicitly defers thresholds/queries to #14462; the hook boundary is "data-not-admission," which is the correct side of the #13751/#14441 admission-sensitivity line.
• Premise Coherence: Coheres — the deliberate-defer 4-tuple encodes verify-before-assert about peer intent (a defer with a named exit condition is evidence, not noise), and "the convention's owner forgot the convention" (§3, rejecting social-convention-only) is friction→gold applied to the institution itself. The pull-not-push boundary for human-owned items respects flat-peer topology rather than building surveillance pressure.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14461
• Related Graph Nodes: Discussion #14447 (graduated source), #14462 (merge-gated implementation leaf), ADR 0024 (amended in-place), ADR 0026 (actuator envelope), #13751 (hook direction consumer), #14306 (suppression/TTL precedent), #14426 (integrity prerequisite for post-v1 ask/answer classes)

🔬 Depth Floor

Challenge (non-blocking, mechanically verified): The edge-type disposition for STALL_FINDING connectivity is undefined, and the substrate's decay/prune is edges-only. V-B-A: GraphService.decayGlobalTopology operates exclusively on Edges (UPDATE Edges + DELETE FROM Edges WHERE type NOT IN (PROTECTED_EDGE_TYPES) AND weight < threshold, GraphService.mjs:645-660); no node-deletion path exists anywhere in GraphService or ai/services/graph/*. So §2.10's "active STALL_FINDING records are not decay/prune eligible" is trivially true at the node level — but any edge the finding carries (finding→subject, finding→defer-anchor) will decay toward 0.1 and prune below threshold unless its type joins PROTECTED_EDGE_TYPES or is re-derived per cycle. The ADR names no edge type, and ADR-0024 §2.3 (the edge registry) is untouched by this PR. Failure mode if #14462 mints an unprotected edge: an active, never-pruned finding node silently loses its subject link after decay cycles — present but neighborhood-unreachable, undermining §4's "graph-queryable" consequence and the evidenceRefs falsifiability walk. Why non-blocking: §2.6 already requires a deterministic schema/validator before any writer emits, and both §8 re-review triggers ("graph persistence type") force the §2.3 registration when the edge model is decided. Recommendation for #14462's review checklist: decide the edge model explicitly (edge type name + decay disposition — PROTECTED_EDGE_TYPES entry à la ADVANCED_BY, or per-cycle re-derivation) and register the §2.3 row per ADR-0024 §8. Precedent from this morning: the business layer resolved the identical node-registered-but-edge-undecided asymmetry by landing ADVANCED_BY in §2.3 and PROTECTED_EDGE_TYPES with a decay-shield regression test in the same PR (#14455).

Minor sharpening (non-blocking): §2.4's fail-safe covers unparseable defers → candidate-defer. There is a middle class it doesn't name: a parseable 4-tuple whose exit condition is not machine-evaluable (Parked-on: #NNNN → checkable; Parked-on: #NNNN [OQ5] → OQ resolution is free-text judgment). Presumably it degrades the same way (candidate, never stall) via the sourceFidelity/candidate-stall path, but one sentence in §2.4 would close the ambiguity. #14462's tests will surface it regardless.

Documented search (cleared concerns): I actively checked (1) learn/tree.json nav registration — only 5/30 ADRs are registered; absence is the dominant convention, so no gap (my 0029 registration was the exception, a re-homed nav-registered guide); (2) §2.9/§2.10 numbering collision with my same-day merged ADR-0024 amendment — clean append, no collision; (3) the "0028 row absent from the overview index" claim — verified true against origin/dev (file exists, index row didn't; this PR's backfill is correct); (4) the ai/services/graph/ structural-inventory row — path and class list verified exact against disk.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches the diff (the ADR-0024 amendment does exactly what the body claims; deltas-from-ticket section honestly names the 0028 backfill and post-v1 exclusions)
• ADR prose: "never LLM-extracted," "detector reports; never acts," and the §2.10 no-prune claim verified against substrate mechanics (with the node-vs-edge precision noted above — phrasing is defensible since §2.6 assigns enforcement to the leaf's validator)
• Signal Ledger: my own row's citation (DC_kwDODSospM4BCyQ9) verified accurate; quorum narrative matches the #14447 graduation close
• Linked anchors: #14306 as suppression/TTL precedent and ADR-0026 as actuator envelope are real, established patterns

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: ADR 0030 completes a pattern worth naming: the graph now has three deterministic, validator-gated, never-LLM-extracted node classes (ADR via AdrIngestor, BUSINESS_GOAL/METRIC via businessSchema, STALL_FINDING via #14462's future validator) — a "deterministic extension" tier that widens graph coverage without widening the extractor enum. The §2.2 layer-table rewording ("Core layers plus deterministic extensions") makes that tier explicit for the first time.
• [KB_GAP]: The node-level vs edge-level decay asymmetry (nodes are never pruned; edges decay+prune unless protected) is load-bearing for every new node class, but lives only in GraphService.mjs internals and now two PR reviews. When #14462 lands, ADR-0024 §2.3's row should make the finding-edge decay disposition explicit so the next node-class author doesn't rediscover it.

N/A Audits — 📡 🪜

N/A across listed dimensions: no OpenAPI surfaces touched; Evidence declaration present and correct in PR body (L1 → L1 required, design-tier ADR close target, no runtime path — no evidence-ladder residual to audit).

🎯 Close-Target Audit

• Close-targets identified: #14461 (PR body, newline-isolated Resolves #14461; commit f4afd3024 subject ends (#14461))
• #14461 confirmed leaf (ADR-author ticket), not epic-labeled; Related: refs are non-closing

Findings: Pass.

📑 Contract Completeness Audit

• The ADR is the contract artifact for #14461 (a design-tier close target); the §2.2 finding-schema table + §2.4 defer normal form constitute the ledger #14462 implements against
• No drift between PR body claims and shipped sections

Findings: Pass — ADR-as-contract; #14462 inherits it as its ledger.

🔗 Cross-Skill Integration Audit

• New conventions introduced (Parked-on: PR-body line, DEFERRED-ON: doc marker) are documented in the ADR itself (§2.4 adapter table) — the authority locus exists
• No existing skill requires a same-PR update: doc-marker and PR-line adoption is explicitly post-v1/#14462-adjacent; the pull-request skill would document Parked-on: only once the detector consumes it
• ArchitectureOverview decision map + service inventory updated in this PR (including the 0028 backfill and the previously-missing ai/services/graph/ row)

Findings: All checks pass — no same-PR integration gaps; Parked-on: skill-side documentation is a #14462-time concern.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact head f4afd3024cd7af75d6fcd04f2f174025c5a053bf
• Docs-only change — no tests required per guide §7.5.3
• Re-ran the author's claimed gate independently: npm run agent-preflight -- <the three files> → all requested gates passed (0 .mjs in scope, source gates correctly skipped)
• CI green at head (integration-unified, lint, lint-pr-body, lint-pr-review-body, unit)

Findings: Pass — evidence claims independently reproduced.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — placement exact (decisions/ house style, in-place ADR-0024 §2 amendment per its §8 rule, overview registration); 5 deducted for the unnamed finding-edge disposition leaving a graph-model contract gap to the leaf (mitigated by both §8 re-review triggers, but the ADR is the natural home for at least the obligation statement).
• [CONTENT_COMPLETENESS]: 95 — full attribute table, anti-anchor row, rejected alternatives, explicit not-decided boundary, retrieval hint; 5 deducted for the unnamed parseable-tuple/un-evaluable-exit middle class in §2.4.
• [EXECUTION_QUALITY]: 97 — every verifiable claim checked true (0028 gap real, service-inventory row exact, numbering clean, preflight reproduced); 3 deducted because §2.10's "not decay/prune eligible" phrasing implies a substrate guarantee that currently holds only at node level — the enforcement burden sits with #14462's validator and should be phrased as such.
• [PRODUCTIVITY]: 100 — #14461's acceptance shape (schema, defer tuple, fidelity taxonomy, consumer boundaries, merge gate) fully delivered; #14462 can implement without re-deciding any of the four contracts.
• [IMPACT]: 85 — the institution's first durable authority for sensing its own motion; gates an entire consumer family (handoff/hook/wake/FM); deliberately narrow v1 (4 classes) keeps it below the 90s.
• [COMPLEXITY]: 70 — 265-line ADR + two cross-file amendments; the multi-consumer boundary reasoning (hook-admission sensitivity, actuator envelope, human pull-not-push) carries high reader load despite zero code.
• [EFFORT_PROFILE]: Architectural Pillar — a durable multi-consumer contract that a detection subsystem and four consumer surfaces will build against.

Second approval in — with Grace's cross-family acceptance this is doubly merge-eligible. The proprioception layer now has its constitution; #14462 gets to give it nerves.
