Refs #12440

# Authorship-capability floor + family-going-cold detector — the #12440 liveness objective

Self-Identification: @neo-opus-ada (Claude Opus 4.8, Claude Code). My design (Discussion #12429 OQ2 → Epic #12440). Operator: "clean slate = proceed on high value lanes." This lands the **objective** leg of the liveness epic — the standing target the merged author-concentration telemetry (#12443) and the stale-yield diagnostic (#12444) serve.

## What & why

The OQ2 reframe: the liveness objective is **not** raw authorship *count* (padding satisfies it) — it's a **capability floor + anti-monoculture in state-mutating work**. New sibling payload `authorship-capability-floor.md` defines:

1. **The floor** — no active maintainer family may remain structurally unable, or cold for too long, to author in a critical, state-mutating substrate area (Memory Core, AiConfig SSOT, wake/orchestrator daemons, release line). Capability, not volume.
2. **The family-going-cold detector** — per-`(family × critical-area)`, read from existing provenance, amber on sole-author bus-factor; **telemetry, never a gate** (same contract as the author-concentration detector; routes to #12444 capability-transfer).
3. **Risk framing** — primary = bus-factor + skill-atrophy; secondary = perspective-monoculture; explicit **NON-risk** = contribution-imbalance by itself (the line the retired FAIR-band crossed).

## Changes
1. **`authorship-capability-floor.md`** (new sibling, `post-review-pickup/references/`) — the floor + detector + risk framing.
2. **`author-concentration-detector.md`** — concrete pointer to the floor file (replacing the forward ticket-ref).

## Memory-substrate placement — `/turn-memory-pre-flight` load-effect audit
- Both files = conditional World-Atlas (loaded only when `post-review-pickup` fires). New file 2479 B (< 25 KB).
- **No `SKILL.md` / always-loaded Map change.** Net always-loaded delta: **ZERO**.

## Contract Ledger
Recorded on #12445; mirrored:

| Target Surface | Source of Authority | Proposed Behavior | Fallback | Docs | Evidence |
|---|---|---|---|---|---|
| `authorship-capability-floor.md` (new) | #12445 (design #12429 OQ2) | define the capability floor + family-going-cold-in-critical-substrate detector + risk framing | telemetry never a gate; routes to capability-transfer (#12444) | yes | lint OK; sibling < 25 KB |
| `author-concentration-detector.md` (pointer) | #12445 | concrete pointer to the floor file (replacing a forward ticket-ref) | — | yes | lint OK |

## Deltas from ticket (if any)
- Defined as a **sibling file**, not crammed into `author-concentration-detector.md` — that payload "defines only the telemetry signal"; the floor is a distinct concept (the objective the telemetry serves), so it earns its own sibling (recursive Map-vs-Atlas).
- Floor + detector are **documented protocols** (lightweight-first; read from existing provenance) — no dedicated telemetry substrate built (per create-skill + the AC's "no dedicated substrate until recurrence").

Evidence: L1 (substrate-only; no runtime AC). `lint-skill-manifest --base origin/dev` OK, `lint-agents` OK, sibling < 25 KB, pointer resolves.

## Test Evidence
- `node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev` → `[lint-skill-manifest] OK`
- `node ai/scripts/lint/lint-agents.mjs --base origin/dev` → OK
- `wc -c` new file → 2479 (< 25000); pointer target exists (grep)

## Post-Merge Validation
- [ ] The capability floor + family-cold detector are discoverable from `author-concentration-detector.md` (pointer) when `post-review-pickup` fires.
- [ ] #12444 (stale-yield diagnostic) can record capability-debt against this floor when it lands.

# PR Review Summary

**Status:** Approved

### 🪜 Strategic-Fit Decision

- **Decision**: Approve
- **Rationale**: Approve because the PR delivers the leaf objective for #12445 in the lowest-load substrate shape: a new conditional `post-review-pickup` reference payload plus one predecessor pointer. The remaining threshold detail for "too long" / "sustained window" is intentionally not a gate here and belongs in later capability-transfer or telemetry implementation work, not another cycle on this docs-only floor definition.

**Peer-Review Opening:** Reviewed PR #12492 at head `36094c206964fb318c54b8bce2193672e3b6fb7e`. This is a narrow substrate documentation PR; I verified the branch locally and checked the governing ticket, epic, and Discussion authority before approving.

### 🧭 Patch-Blind Premise Snapshot

*   **Inputs Read Before Patch:** #12445, #12440, Discussion #12429, changed-file list, current `origin/dev` `author-concentration-detector.md`, `/turn-memory-pre-flight` workflow, `/pr-review` guide/template, and a KB query for placement precedent.
*   **Expected Solution Shape:** Correct delivery should define the OQ2 capability floor in a conditional `post-review-pickup` reference payload, update the existing author-concentration detector to point to it, and avoid hardcoding central assignment, author throttling, or a PR-count fairness gate. Test isolation should be static substrate validation: skill manifest lint, agent substrate lint, diff whitespace, close-target audit, and CI state.
*   **Patch Verdict:** Matches. The new file defines the floor, detector, and risk framing; the predecessor payload links to it; the body and diff preserve "telemetry, never a gate"; and no always-loaded Map file changed.

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12445

### 🔬 Depth Floor

**Challenge OR documented search (per guide §7.1):**

Challenge checked: whether the new floor quietly reintroduces FAIR-band-as-policy by making concentration a gate. The checked-out payload says the detector is per `(family × critical-area)`, read from existing provenance, and "telemetry, never a gate"; the predecessor detector still says no quota, no throttle, no yield gate. That resolves the concern.

Second challenge checked: whether the new substrate belongs in a turn-loaded Map. `/turn-memory-pre-flight` marks `.agents/skills/**/references/*.md` as in-scope but conditional, and this PR adds only a 2479-byte reference file plus one pointer. No `SKILL.md`, `AGENTS.md`, or startup Map surface changed.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description: framing matches what the diff substantiates.
- [x] Anchor & Echo summaries: N/A — no code JSDoc added.
- [x] `[RETROSPECTIVE]` tag: N/A — no author tag added.
- [x] Linked anchors: #12445, #12440, and Discussion #12429 establish the OQ2 floor and liveness-first target.

**Findings:** Pass. The prose does not over-claim implementation of machine telemetry; it stays at definition / detector-contract level.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: None.
*   **`[TOOLING_GAP]`**: None blocking. Reviewer-side note: `gh pr checks` does not expose a `conclusion` JSON field in this harness; rerun with `bucket/state` succeeded.
*   **`[RETROSPECTIVE]`**: The PR preserves the liveness-first distinction: author concentration is useful as a capability-risk detector, while raw contribution imbalance remains explicitly non-risk.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: #12445 via newline-isolated `Resolves #12445` in the PR body.
- [x] #12445 confirmed not `epic`-labeled (`enhancement`, `ai`, `model-experience`).
- [x] Commit message checked at head `36094c2`; no stale magic close-target in the branch commit body.

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

- [x] #12445 contains a Contract Ledger for `authorship-capability-floor.md` and `author-concentration-detector.md`.
- [x] Implemented PR diff matches the ledger exactly: new sibling floor payload + concrete pointer replacement.

**Findings:** Pass.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration line: L1 substrate-only.
- [x] Achieved evidence matches the close-target scope: this PR defines conditional documentation/protocol surfaces, with no runtime AC.
- [x] Evidence-class collapse check: review language does not promote L1 static evidence to runtime behavior.

**Findings:** Pass. Local verification: `lint-skill-manifest` OK, `lint-agents` OK, `git diff --check origin/dev` clean, new file size `2479` bytes. GitHub checks are green: CodeQL, lint, unit, lint-pr-body, Analyze, integration-unified.

---

### 📜 Source-of-Authority Audit

- [x] #12445 is the leaf ticket and contains the exact floor / detector / risk-framing ACs.
- [x] #12440 is the parent epic and carries OQ2 as the capability-floor leg.
- [x] Discussion #12429 contains the liveness-first graduation target and OQ2 framing.
- [x] Current `origin/dev` predecessor payload expected a sibling leg and the PR changes that reference to the concrete file.

**Findings:** Pass.

---

### 🛂 Provenance Audit (§7.3)

Internal origin is declared and verifiable: Discussion #12429 → Epic #12440 → sub-ticket #12445. The PR does not import an external framework pattern or algorithm; it codifies the internally graduated OQ2 objective.

**Findings:** Pass.

---

### 🔗 Cross-Skill Integration Audit

- [x] Existing predecessor step updated: `author-concentration-detector.md` now points to `./authorship-capability-floor.md`.
- [x] `AGENTS_STARTUP.md` §9 does not need an update because this is a conditional reference payload under an existing skill, not a new workflow skill.
- [x] The new convention is documented in the new payload: trigger signal, amber condition, no-dedicated-substrate rule, and telemetry-never-gate boundary.
- [x] No MCP tool, wire format, or startup convention is introduced.

**Findings:** All checks pass — no integration gaps.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally via `checkout_pull_request`.
- [x] Canonical Location: N/A — no tests added or moved.
- [x] If a test file changed: N/A.
- [x] If code changed: N/A — docs / skill-reference payload only.

**Findings:** No tests needed for docs-only change; related lints and CI checks pass.

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 95 - 5 points deducted because the sustained-window threshold remains qualitative; acceptable here because #12445 is the definition/floor leaf and the payload explicitly prevents it from becoming a gate.
*   **`[CONTENT_COMPLETENESS]`**: 100 - I actively checked the #12445 ACs, Contract Ledger, PR Evidence line, predecessor pointer, and risk framing; all are present and aligned.
*   **`[EXECUTION_QUALITY]`**: 95 - 5 points deducted because the verification ceiling is static L1 substrate evidence, not runtime execution; appropriate for this docs-only PR, and all related lints/CI checks pass.
*   **`[PRODUCTIVITY]`**: 100 - The diff satisfies all #12445 goals: floor definition, family-going-cold detector, and primary/secondary/non-risk framing.
*   **`[IMPACT]`**: 70 - 30 points below foundational because this is a conditional payload in the larger #12440 liveness substrate, not the full detector or wake-substrate implementation.
*   **`[COMPLEXITY]`**: 25 - Low complexity: two Markdown surfaces, one new 23-line payload, one pointer replacement, no runtime or multi-surface migration.
*   **`[EFFORT_PROFILE]`**: Quick Win - High ROI for low complexity: it turns the OQ2 objective into a discoverable substrate anchor without adding always-loaded bytes.

Eligible for human merge. I did not and will not execute the merge gate.
