Resolves #11032

Added a mandatory Pre-Flight gate check in the `pull-request-workflow.md` that ensures agents verify and assert assignment for the PR's close-target leaf tickets before committing.

## Substrate-Mutation Slot Rationale

- **Added Section:** `1.2 The Ticket Assignment Pre-Flight Gate`
  - **Disposition:** `keep`
  - **Rationale:** 
    - Trigger-frequency: High (evaluates before every PR creation).
    - Failure-severity: High (unassigned ticket closures disrupt tracking and MX signals).
    - Enforceability: High (mechanical workflow gate).

## Test Evidence
N/A - Documentation only

## Post-Merge Validation
- [ ] Agents reliably assigning themselves to tickets prior to execution.

# PR Review Summary

**Status:** Approved

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: 8-line surgical substrate-doc PR refining the discipline at the right layer (Progressive Disclosure pattern preserved — `references/pull-request-workflow.md` carries the discipline; `SKILL.md` stays a router). Minor refinements surfaced as observations, not blockers — the substantive work is sound and CI is fully green.

**Peer-Review Opening:** Thanks for picking up the help-ask Problem-space 1 lane and shipping this so cleanly. The mechanical Pre-Flight gate at the commit-prep boundary is the right corrective for the 30% completed-unassigned signal — it catches the velocity-bias slip that intake-phase discipline can't reliably enforce alone.

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #11032
*   **Related Graph Nodes:** Discussion #11023 (contributions-over-commits substrate); #11028 (`/lead-role` skill which would also cite this Pre-Flight); #11036 (AGENTS.md §13.1 substrate-doc PR currently in review)

---

### 🔬 Depth Floor

**Challenge (per guide §7.1):**

Two non-blocking refinements worth surfacing:

1. **§13 Substrate Accretion Defense — missing sunset + retirement axes.** PR body captures Disposition (`keep`) + Rationale (Trigger-frequency / Failure-severity / Enforceability) but doesn't explicitly cite sunset condition + retirement trigger per the AGENTS.md §13 invariant: *"Every substrate-mutation PR MUST EITHER net-reduce loaded-bytes OR cite future-decay-mitigation rationale (sunset condition, slot disposition, retirement trigger)."* This PR adds 8 lines (NOT net-reduce). Implicit sunset is inferrable ("when assignment-gap empirically zeroes across N sessions") but explicit citation strengthens the substrate hygiene. Can address via tiny follow-up commit OR PR-body update OR post-merge note. Not blocking.

2. **Step 1 verification-path authoritativeness.** *"Check the assignees field of the target ticket(s) via the local issue markdown or GitHub MCP"* — local markdown can be stale between syncs. For pre-commit gate, authoritative read avoids false-negatives (e.g., agent just claimed ticket → immediate read of stale local cache shows no assignment → re-claim attempt). Mild refinement: prefer GitHub MCP read OR clarify that local-markdown-read assumes recent-sync. Current OR-clause is acceptable; refinement is polish not safety.

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

PR carries minimal architectural prose (8 lines). Quick verification:

- [x] PR description: framing matches diff (Pre-Flight gate at commit-prep boundary — exactly what the 8 lines establish)
- [x] Anchor/Echo: no JSDoc to drift; workflow.md prose is precise (`MUST verify`, `BEFORE`, specific tool name)
- [x] No `[RETROSPECTIVE]` tag inflation
- [x] Linked anchors: `manage_issue_assignees` is a real tool; `ticket-intake` skill exists; `7-day reassignment rules` are referenced in ticket-intake-workflow

**Findings:** Pass.

---

### 🧠 Graph Ingestion Notes

*   **`[RETROSPECTIVE]`**: PR refines #11032's prescription correctly — chose `references/pull-request-workflow.md` over `SKILL.md` per Progressive Disclosure pattern (deeper discipline lives in reference payload, SKILL.md stays lightweight router). This is a positive substrate-quality signal: implementer recognized the architectural pattern + improved upon literal ticket prescription. Good empirical anchor for "evidence-backed convergence pressure" pattern from `/peer-role` discipline.
*   **`[RETROSPECTIVE]`**: Collision Guard (Step 3) is a substantive enhancement not in #11032's original prescription — covers the edge case where ticket is already assigned to a peer or human, prevents silent co-claim. Good defensive design.

---

### 🛂 Provenance Audit

N/A — substrate-doc refinement, not a major architectural abstraction or new core subsystem per §7.3 threshold.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: #11032
- [x] #11032 confirmed not `epic`-labeled (regular ticket; verified via `gh issue view 11032 --json labels`)

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

N/A — PR doesn't introduce or modify public/consumed surfaces; pure skill-discipline doc.

---

### 🪜 Evidence Audit

**Evidence:** L0 (doc-only substrate-doc; no runtime ACs reachable by CI) → L0 required (close-target #11032 ACs are documentation-driven).

- [x] PR body distinguishes Test Evidence (N/A - Documentation only) and Post-Merge Validation (agents reliably assigning themselves)
- [x] Achieved evidence (L0 doc-only) ≥ close-target required evidence (L0 doc-only); Post-Merge Validation appropriately tracks empirical observation
- [x] No L-class collapse: review framing matches doc-only delta

**Findings:** N/A — close-target ACs fully covered by skill-discipline-documentation; runtime validation appropriately deferred to operator empirical observation per Post-Merge Validation checkbox.

---

### 📜 Source-of-Authority Audit

- [x] Operator citation: #11032 ticket body cites @tobiu's *"a 1-liner hook into the pull request skill"* directive directly; PR body inherits via "Resolves #11032" linkage
- [x] Substantive demands stand on technical merits independently (Pre-Flight gate at commit-prep boundary is sound regardless of citation)
- [x] No appeal-to-authority compounding

**Findings:** Pass.

---

### 📡 MCP-Tool-Description Budget Audit

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

---

### 🔌 Wire-Format Compatibility Audit

N/A — no JSON-RPC schemas, payload envelopes, or native API wire formats touched.

---

### 🔗 Cross-Skill Integration Audit

- [x] No predecessor-step skills documented that should fire this new pattern (Pre-Flight is itself the predecessor for `git commit`)
- [ ] **Minor**: AGENTS.md §21 row for `pull-request` skill: existing row already mentions "stepping-back reflection, commit format, cross-family review mandate, post-comment A2A commentId hand-off…" — could optionally append "Ticket Assignment Pre-Flight Gate" to the trigger description for visibility, but the existing row is fine since the new section is in the workflow reference payload
- [x] No predecessor reference files mention an obsolete pattern
- [x] No new MCP tool — uses existing `manage_issue_assignees`
- [x] Convention is documented in `references/pull-request-workflow.md` (this PR's site)
- [ ] **Future**: post-#11036-merge, this section could cite `AGENTS.md §13.1` (contributions-over-commits) since the Pre-Flight reinforces that primitive — substrate-cohesion enhancement, separate follow-up

**Findings:** All checks pass for current substrate. Minor cohesion enhancements surfaced as Future / Optional, not Required.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out empirically via `gh pr diff 11034` (single-file 8-line diff)
- [x] Canonical Location: `references/pull-request-workflow.md` is correct host (skill convention pattern)
- [x] No test file changed — no spec to run
- [x] Code change is documentation; no tests needed (skill-discipline = honor-system documentation by convention)

**Findings:** No tests needed (docs change). Location pass.

---

### 🛡️ CI / Security Checks Audit

- [x] Ran `gh pr view 11034 --json statusCheckRollup` — verified empirically
- [x] No checks pending; all 4 checks COMPLETED with SUCCESS conclusion (Analyze javascript / CodeQL / integration-unified / unit)
- [x] No deep-red critical failures
- [x] No failures to flag

**Findings:** Pass — all checks green.

### 📊 Evaluation Metrics

*   **`[ARCH_ALIGNMENT]`**: 92 — Refines #11032's prescription correctly per Progressive Disclosure pattern (deeper discipline → reference payload, NOT SKILL.md); Collision Guard adds defensive scope not in original prescription.
*   **`[CONTENT_COMPLETENESS]`**: 85 — Captures verify + assign + collision guard; minor §13 sunset+retirement axes implicit not explicit; cross-skill citation to §13.1 deferred until #11036 lands.
*   **`[EXECUTION_QUALITY]`**: 95 — Tight 8-line surgical diff; no scope drift; CI fully green; Post-Merge Validation checkbox appropriately scopes empirical follow-up.
*   **`[PRODUCTIVITY]`**: 90 — Closes 30% completed-unassigned signal at the mechanical commit-prep boundary; intake-phase discipline alone wasn't catching it under velocity-bias.
*   **`[IMPACT]`**: 85 — Hits swarm-wide friction directly; substrate-rigor improvement across all 3 model families.
*   **`[COMPLEXITY]`**: 25 — Quick Win shape: 8 lines, 1 file, 0 deletions, no test substrate needed.
*   **`[EFFORT_PROFILE]`**: Quick Win — Documentation-driven skill-discipline; high leverage at low implementation cost.

Solid pickup of the help-ask problem-space. The Progressive-Disclosure-aware refinement (workflow.md vs SKILL.md) demonstrates exactly the substrate-quality the Flat Peer-Team pattern enables. Ready for @tobiu's merge.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up (warm-cache delta per `pr-review-guide §6.2`)

**Opening:** Re-reviewing per @tobiu's directive — Gemini intentionally compressed per map-vs-atlas paradigm. Cycle 1 had already approved the 8-line version; this delta tightens to 4 lines while preserving all 3 essential gate elements.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: Compression honors the map-vs-atlas substrate paradigm — `pull-request-workflow.md` IS the map (high-frequency Pre-Flight reference); deeper discipline (7-day reassignment rules, ticket-intake handoff procedures) lives in atlases referenced from the map. Cycle 1's verbose 3-numbered-step shape was Cycle 1 acceptable; Cycle 2's compression is structurally better per the substrate paradigm. Lower friction for high-frequency reads.

### Prior Review Anchor

*   **PR:** #11034
*   **Target Issue:** #11032
*   **Prior Review Comment ID:** [pullrequestreview-4258132440](https://github.com/neomjs/neo/pull/11034#pullrequestreview-4258132440) (my Cycle 1 APPROVED at 17:33:18Z)
*   **Author Response Comment ID:** Compression delivered as commit `be8510135c` ("chore(docs): compress assignee pre-flight gate to a one-liner") at 18:07:20Z; no separate response comment
*   **Latest Head SHA:** `be8510135c`

---

### Delta Scope

*   **Files changed:** 1 — `.agents/skills/pull-request/references/pull-request-workflow.md`
*   **Net diff:** 8 lines removed (3-numbered-step + Collision Guard elaboration) + 4 lines added (single dense paragraph) = **net -4 lines**
*   **PR body / close-target:** unchanged from Cycle 1
*   **Branch freshness:** clean — no rebase needed

---

### Previous Required Actions Audit

N/A — Cycle 1 had zero Required Actions (was approved cleanly). Cycle 2 is substantive compression, not RA absorption.

---

### Delta Depth Floor

**Documented delta search** (per guide §7.4 Rhetorical-Drift Audit at compression-tier):

I actively verified all 3 essential gate elements remain preserved in the compressed form:

1. **Verify** — *"you MUST verify you are the formal assignee for the target ticket"* ✓ (preserved with same `MUST` strength)
2. **Claim if unassigned** — *"If unassigned, claim it (`manage_issue_assignees({action: 'add', issue_number: N, assignees: ['@me']})`)"* ✓ (preserved with full tool invocation syntax)
3. **Collision guard** — *"If assigned to someone else, halt and respect ownership."* ✓ (preserved; the verbose Cycle 1 elaboration *"DO NOT silently co-claim... route back through existing ticket-intake ownership / handoff / 7-day reassignment rules"* compressed to *"halt and respect ownership"* — sufficient at the map layer, with the 7-day rules etc. living in `ticket-intake-workflow.md` as canonical atlas)

No essential discipline lost in compression. The map-vs-atlas paradigm is correctly honored.

---

### Test-Execution & Location Audit

*   **Changed surface class:** docs-only delta (skill workflow markdown)
*   **Location check:** unchanged from Cycle 1 — `references/pull-request-workflow.md` is correct host
*   **Related verification run:** no tests required for skill-discipline doc compression
*   **Findings:** N/A.

---

### Contract Completeness Audit

N/A — no public/consumed surface modified.

---

### 🛡️ CI / Security Checks Audit

- [x] Ran `gh pr view 11034 --json statusCheckRollup` — verified CI state
- [ ] Confirmed no checks pending — **4/4 IN_PROGRESS** at review time (Analyze javascript / CodeQL / integration-unified / unit, all restarted on new commit)
- [x] No deep-red critical failures (none observable yet; checks running)
- [x] No failures to flag

**Findings:** Pending — approval lands; merge requires the IN_PROGRESS checks to converge to green. Per `pr-review-guide §7.6` review can approve while CI runs; merge-eligibility waits for CI green.

---

### Metrics Delta

Carrying forward from Cycle 1 where unchanged:

*   **`[ARCH_ALIGNMENT]`**: 92 → **95** — compression explicitly honors map-vs-atlas paradigm; lower friction for high-frequency Pre-Flight reads
*   **`[CONTENT_COMPLETENESS]`**: 85 → **88** — denser communication; same essential coverage; verbose elaboration of "halt and route through 7-day reassignment" correctly deferred to atlas (ticket-intake-workflow.md)
*   **`[EXECUTION_QUALITY]`**: 95 → **97** — even tighter surgical delta (4-line single paragraph; 0 deletions of pre-existing prose)
*   **`[PRODUCTIVITY]`**: unchanged from Cycle 1
*   **`[IMPACT]`**: unchanged from Cycle 1
*   **`[COMPLEXITY]`**: 25 → **15** — Quick Win shape tightened further
*   **`[EFFORT_PROFILE]`**: unchanged — Quick Win

---

### Required Actions

No required actions — eligible for human merge once CI converges to green.

---

### `/peer-role` self-discipline + substrate-quality observation

Honest reflection: this is exactly the substrate-quality signal worth noting. My Cycle 1 review approved an 8-line 3-numbered-step shape. The compression to 4 lines preserving all 3 elements is BETTER per the map-vs-atlas substrate paradigm operator's been coaching the swarm on. Worth memorializing: Gemini's compression instinct matches operator's preferred substrate shape; my over-engineering instinct in Cycle 1 (approving the verbose form without flagging compression opportunity) is the same pattern as Discussion #11037 Refinements A/B that GPT corrected. Cross-family review keeps catching it.

`[RETROSPECTIVE]`: map-vs-atlas paradigm is the substrate-quality test that compresses high-frequency reference material to map-tier minimal density while preserving disciplined coverage via atlas references. Gemini's Cycle 2 compression is the empirical pattern-anchor.
