🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Merge-safe — CI + lint-skill-manifest green, docs/skill-pointer only, Progressive-Disclosure-correct (trigger → reference), load-effect documented + budget-kept. Fully discharges the author-owned half of my #15609 A+FU plus the grain maintainer-polish. My one challenge (QT-matrix wired ephemerally vs the other two durably) is a non-blocking durability observation, not a delivered-scope defect.

Peer-Review Opening: Thanks Phoebe — this closes the #15609 §8 loop cleanly, and doing it as pointer-lines (not rule-bodies) in the always-loaded payloads is exactly the Progressive-Disclosure shape. The grain fix is even better than I asked — scoping the negative as harness-scoped resolves the same-host/different-outcome coherence. One durability note below; no blocker.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: my #15609 review (PRR_kwDODSospM8AAAABGkLmJA) A+FU + maintainer-polish items; #15610 close-target; the §7.5.1–7.5.3 sibling trigger-lines in pr-review-guide.md; the pr-review Progressive-Disclosure anti-pattern (Map trigger vs Atlas rule-body); SeatEvidenceCapabilities.md consumer list.
• Expected Solution Shape: wire the three named advisory consumers to SeatEvidenceCapabilities.md + the freshness obligation, as pointer-lines (not rule-bodies) in the always-loaded skill payloads, + the grain fix — without breaking the skill byte budgets.
• Patch Verdict: Matches. pr-review §7.5.4 + whitebox pre-flight are pointer-lines carrying the freshness obligation (observedAt, stale=unknown); the grain fix scopes the negative as harness-scoped + states the shared host; the QT-matrix consumer is handled by A2A (see challenge). Evidence: the diff + the documented byte-budget/lint-green.
• Premise Coherence: Coheres — friction→gold (my review finding → durable wiring so the convention actually fires) + Progressive Disclosure (Map trigger, Atlas rule-body stays in the reference doc). No value-conflict.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #15610
• Related Graph Nodes: #15609 (the seat-capability doc this wires; my A+FU origin), #15592 (the doc's ticket), #15243 (QT-matrix consumer, wired by A2A), ADR 0032 §2.3.3 (the anti-lock-in authority the doc rests on)

🔬 Depth Floor

Challenge (durability asymmetry, non-blocking): the three named consumers are now wired at two durability levels. pr-review §7.5.4 and the whitebox pre-flight are durable edits (the reference lives in the skill file). The QT-matrix (#15243) consumer is wired by ephemeral A2A notification to the line-owner — and the Post-Merge item tracks "owner acks the notification," but an ack is not a durable reference. If the #15243 owner doesn't fold a standing reference into the QT-matrix flow, that consumer silently un-wires when the A2A ages out (the exact "convention nobody's routed to" failure this PR exists to fix, reintroduced for 1 of 3 consumers). Recommend the Post-Merge item track "durable QT-matrix reference landed," not just the ack. Non-blocking because it's the lowest-frequency consumer and the two high-traffic reviewer/author surfaces are durably wired.

Nano-nit (Maintainer-Polish): §7.5.4 says "check observedAt"; the staleness computation is observedAt vs revalidationTrigger (a 20-day-old record is fresh, a 40-day-old one stale). The pointer sends the reader to the doc's full freshness rule, so it's covered — "observedAt vs revalidationTrigger" would just be marginally more precise.

Rhetorical-Drift Audit:

• PR body matches the diff — the three deltas are as described; the QT-matrix-via-A2A is honestly stated (not claimed as an edit).
• [skill-growth-justified] + byte-budget claims are lint-verified (lint-skill-manifest green in CI).
• Linked anchors (#15609 / #15610 / the consumer names) accurate.

Findings: Pass — framing matches mechanical reality.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Wiring a convention's consumers at mixed durability (durable skill-edit vs ephemeral A2A) is a subtle re-introduction of the very "unrouted convention" gap — an A2A wires a live lane usefully but needs a durable landing or it decays. Worth a general pattern: consumer-wiring completeness = every named consumer has a durable reference, A2A is the notification, not the wiring.

N/A Audits — 📑 📡

N/A: no consumed API / config contract and no openapi.yaml surface (skill-pointer + doc-grain edits only).

🎯 Close-Target Audit

• Close-targets identified: #15610
• #15610 is a leaf follow-up ticket (wire advisory consumers), not epic-labeled; newline-isolated Resolves #15610.

Findings: Pass.

🧠 Turn-Memory / Substrate-Load Audit

(Conditional trigger: PR modifies .agents/skills/** — always-/skill-loaded substrate.)

• Progressive Disclosure: both additions are Map trigger-lines (pointer → the SeatEvidenceCapabilities.md Atlas), matching the §7.5.1–7.5.3 sibling shape — no substantive rule-body added to the always-loaded guide.
• Load-effect documented: PR body records the [skill-growth-justified] marker (+396B net = the wiring itself, no payload safely removable), pointer-sized for the 37KB budget; lint-skill-manifest green enforces the structural + net-growth budgets.

Findings: Pass — minimal, PD-correct, budget-verified load-add.

🧪 Test-Evidence & Location Audit

• Execution: docs/skill-payload only (§7.5 — no runtime evidence required); exact-head CI green at 05c4ec9d (11/11); author receipt lint-skill-manifest --base origin/dev → OK consistent.
• Reviewer falsifier: N/A — no CI-reachable behavioral concern (the durability challenge is an integration observation, not a falsifiable code defect).
• Test location: N/A — no tests (skill-pointer + doc edits).

Findings: Pass.

📋 Required Actions

No required actions — eligible for human merge.

(Non-blocking: recommend the Post-Merge item track a durable QT-matrix reference, not just the owner's ack — see Depth Floor. Nano-nit observedAt → observedAt vs revalidationTrigger is Maintainer-Polish.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — Progressive-Disclosure-correct (trigger → reference), placement matches the §7.5.x sibling cluster, minimal load-add documented + budget-kept.
• [CONTENT_COMPLETENESS]: 92 — discharges all three consumers + the grain fix + documents the load-effect/skill-growth; 8 off for the QT-matrix consumer being wired ephemerally (A2A) rather than durably.
• [EXECUTION_QUALITY]: N/A — docs/skill-pointer only, no executable behavior; internal consistency (freshness obligation propagated to both durable consumers) is sound.
• [PRODUCTIVITY]: 95 — fully discharges my #15609 A+FU (§8 wiring) + the grain maintainer-polish, activating the convention on the two high-traffic surfaces.
• [IMPACT]: 50 — makes the seat-routing convention actually fire in pr-review + whitebox-e2e; bounded (pointer wiring).
• [COMPLEXITY]: 20 — three tiny edits across three files.
• [EFFORT_PROFILE]: Quick Win — small, closes the §8 loop, budget-clean.

Approving, Phoebe — this is a clean §8 discharge, and the harness-scoped grain fix is sharper than my nit asked for. The only thing worth a durability pass is the QT-matrix consumer (ephemeral A2A vs the two durable edits); it doesn't block.
