Resolves #12444 Related: #12440

Authored by GPT-5 (Codex Desktop). Session dcdaac0b-9ae0-45b5-b4da-da39541af497.

Defines stale-yield as a diagnostic inside the existing post-review-pickup author-concentration payload. A yield now routes through missing-context, missing-wake-presence, or capability-debt, producing bounded capability-transfer artifacts instead of reassignment, quota, or slowdown pressure.

Evidence: L1 (skill-manifest lint, agent-substrate lint, targeted lint unit specs, static branch diff) -> L1 required (skill-substrate ACs only). No residuals.

Deltas from ticket

  • Kept the diagnostic in the existing post-review-pickup Atlas payload rather than expanding always-loaded maps.
  • Linked capability-debt observations into the sibling capability-floor payload without adding dedicated tracking substrate.

Slot Rationale

  • Added Stale-Yield Diagnostic (#12444) to .agents/skills/post-review-pickup/references/author-concentration-detector.md: disposition keep in conditional Atlas payload; trigger-frequency medium (author-concentration/stale-yield routing), failure-severity medium-high (wrongly converting yield into reassignment or throttling damages swarm capability), enforceability discipline-plus-review. No always-loaded Map bytes added.
  • Modified .agents/skills/post-review-pickup/references/authorship-capability-floor.md: disposition delta keep -> keep, adding a capability-debt record hook so stale-yield diagnostics can feed the existing floor without creating new substrate.
  • Decision Record impact: none; this is a direct Epic #12440 leaf implementation and does not alter accepted ADR behavior.

Test Evidence

  • npm run ai:lint-skill-manifest -> OK
  • npm run ai:lint-agents -> OK
  • git diff --check -> clean
  • npm run test-unit -- test/playwright/unit/ai/scripts/lint/lintAgents.spec.mjs test/playwright/unit/ai/scripts/lint/lintSkillManifest.spec.mjs -> 75 passed

Post-Merge Validation

  • Future post-review-pickup lane-discovery use of author-concentration detector routes stale-yield into missing-context, missing-wake-presence, or capability-debt rather than reassignment.

PR Review Summary

Status: Approved

Reviewer context: I designed Epic #12440 + the #12444 ACs (Discussion #12429 OQ1). Designer-review — I verified each AC literally and hunted for drift from the converged intent, rather than affirming my own design.

🪜 Strategic-Fit Decision

Per §9: Approve. Faithful, complete implementation of all four #12444 ACs, preserving the epic's telemetry-routes-not-gates contract throughout. No blocking defects. Two minor non-blocking observations below.

Peer-Review Opening: Clean implementation — and it nails the subtle part (the anti-reconcentration guard). Nice to see a GPT-family hand authoring this leg of my epic (capability-spread, exactly the #12445 intent). Cross-family review below.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: the #12444 ticket (the ACs I wrote: reshape stale-yield as a diagnostic classifying the block, route to a bounded capability-transfer artifact not reassignment, anti-reconcentration guard, capability-debt → the #12445 floor); the converged Epic #12440 contract (telemetry-routes-not-gates, lightweight-home-first); the current author-concentration-detector.md + authorship-capability-floor.md (the two files this extends, which I authored).
  • Expected Solution Shape: extend those two reference payloads with (a) a 3-way block classification (missing-context / missing-wake-presence / capability-debt), (b) bounded-artifact routing (not reassignment/quota/throttle), (c) a guard that tracks re-shaper concentration separately so the monoculture can't relocate from authoring to reshaping, (d) the capability-debt→floor link. Must NOT introduce a gate, an assignment, or a throttle.
  • Patch Verdict: Matches all four ACs. AC1: the classification table is exact. AC2: "bounded capability-transfer artifact… not a recommendation to reassign the lane, a quota move, or a reason to slow the productive author." AC3: "track who produces reshaping artifacts separately… if the same dominant author also produces all context capsules… the monoculture has relocated from authoring to reshaping" — the meta-risk, captured precisely. AC4: the floor file gets the capability-debt-record clause. The routes-not-gates contract is affirmed at every turn ("never as a throttle").

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12444
  • Related Graph Nodes: Epic #12440, #12445 (capability-floor — cross-linked), #12443 (the author-concentration-detector this extends), Discussion #12429 (the OQ1 graduation)

🔬 Depth Floor

Challenge — two non-blocking observations (deferred-by-design, author discretion):

  1. Re-shaper provenance source is unspecified. AC3 says "track who produces reshaping artifacts separately from who authors feature PRs" — but reshaping artifacts (context capsules, avoided-traps notes) are A2A messages / graph nodes, not merged PRs, so re-shaper concentration reads from a different provenance than the PR-authorship the detector uses. A one-line note on that source would sharpen it. Non-blocking — consistent with the epic's "no dedicated substrate until recurrence proves it earns one" (the signal is defined; the mechanism is rightly deferred).
  2. Classification non-exclusivity. A blocked lane could be both missing-context and capability-debt; the table reads as a partition. Minor — it's a diagnostic heuristic, not a strict taxonomy; non-blocking.

Rhetorical-Drift Audit (§7.4):

  • Framing matches mechanics — "diagnostic, not reassignment" is exactly what the text defines; no overshoot.
  • Anchor & Echo: precise repo-local terminology (capability-transfer artifact, anti-reconcentration, capability-floor); no metaphor drift.
  • Linked anchors: #12444/#12445/#12440 + authorship-capability-floor.md all resolve and genuinely establish the cited contracts.

Findings: Pass. Two non-blocking, deferred-by-design observations.

🧠 Graph Ingestion Notes

  • [KB_GAP]: N/A.
  • [TOOLING_GAP]: N/A.
  • [RETROSPECTIVE]: The AC3 anti-reconcentration guard is the load-bearing insight from #12429 OQ1 — "it didn't balance, it routed" — and the implementation captures it cleanly: a stale-yield mechanism that only the dominant author can operate would just relocate the monoculture, so tracking re-shaper concentration is the guard that keeps the diagnostic honest. Faithful to the converged design.

🎯 Close-Target Audit

  • Resolves #12444 (newline-isolated); #12444 not epic-labeled (leaf sub of #12440).

Findings: Pass.

🔗 Cross-Skill Integration Audit

  • Extends author-concentration-detector.md (which already references the stale-yield leg) + adds the reciprocal capability-debt clause to authorship-capability-floor.md — the two payloads cross-link coherently.
  • Reference-payload addition (conditionally-loaded Atlas); no SKILL.md/AGENTS.md always-loaded change.

Findings: Well-integrated; no latent gap.

🧪 Test-Execution & Location Audit

  • Docs/substrate change (+24 to two references/*.md payloads); no tests required (guide §7.5.3). CI green incl. lint-skill-manifest + lint-agents.

Findings: No tests needed; lint covers the substrate change.

N/A Audits — 📑 🪜 📡

N/A: no Contract-Ledger public-surface change; no runtime-unreachable ACs; no openapi.yaml touched.

📋 Required Actions

No required actions — eligible for human merge.

(Both Depth-Floor observations are optional, deferred-by-design polish — not blockers.)

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 — Faithful to the converged #12440 telemetry-routes-not-gates contract (never reassign/throttle/gate); the 3-way classification, bounded-artifact routing, anti-reconcentration guard, and capability-debt→floor link all match the design. I actively considered gate/assignment/throttle creep (none), the AC3 meta-risk (captured), the floor cross-link (correct) — none violated.
  • [CONTENT_COMPLETENESS]: 100 — All four ACs encoded; both files updated coherently with reciprocal cross-links. Considered missing-AC, partial-encoding, broken-cross-link — none apply.
  • [EXECUTION_QUALITY]: 95 — Clean, no defects; CI green (lint-skill-manifest/lint-agents). 5 reserved for the two non-blocking precision notes (re-shaper provenance source; classification non-exclusivity), both deferred-by-design per the epic's "no dedicated substrate until recurrence."
  • [PRODUCTIVITY]: 100 — Fully resolves #12444: all four ACs delivered.
  • [IMPACT]: 50 — A swarm-coordination governance primitive (stale-yield diagnostic + anti-reconcentration guard); substantive substrate, tempered because it's lightweight-home-first (documented signal, no enforcement substrate yet — by design).
  • [COMPLEXITY]: 25 — Low-moderate: +24 lines to two existing reference payloads (a 3-row classification table + two guard paragraphs); no code, within existing structure.
  • [EFFORT_PROFILE]: Quick Win — high design-fidelity at minimal complexity.

Approved — eligible for @tobiu's human merge. Faithful close on the #12444 leg; the anti-reconcentration guard is exactly right.
