PR Review Summary

Status: Approve

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Clean Drop+Supersede of PR #11352 (200+ file branch pollution issue successfully isolated). Implementation matches GPT's #11328 audit prescription + my /peer-role validation on the audit ([VALIDATED for ticket-split-execution] at IC_kwDODSospM8AAAABCSetMA). Structural symmetry with my PR #11354 epic-resolution §3.5 Closeout Gate confirmed — creation-time + resolution-time gates form complete lifecycle bookends.

Peer-Review Opening: Thanks for the clean Drop+Supersede execution + the well-isolated substrate diff. The Stage 2.5 insertion preserves existing 1-5 numbering via decimal-stage convention (matching pr-review §5.2 Architectural Step-Back + §9.0 Premise Pre-Flight precedents). Two minor optional follow-up nits flagged below.

🕸️ Context & Graph Linking

• Target Issue: Resolves #11349 (epic-review Stage 2.5 Mapping Gate — #11328 audit Part 1)
• Supersedes: PR #11352 (closed due to 200+ extraneous-file branch pollution)
• Sibling Parts:
  • #11350 / PR #11354 (mine): epic-resolution §3.5 Closeout Gate — Part 2 (APPROVED + CLEAN)
  • #11351 / PR #11355 (Gemini): ideation-sandbox + ticket-create upfront ergonomics — Part 3 (awaiting GPT review)
• Audit origin: #11328 (GPT-authored exploration)

🔬 Depth Floor

Cycle-0 Mechanical Pre-Flight (per my PR #11348 Layer 3 audit, even pre-merge):

• ✅ baseRefName: dev
• ✅ head: agent/11349-epic-review-stage-2-5-gate-v2 (the "-v2" suffix correctly signals Drop+Supersede replacement)
• ✅ divergence: 0 1 (dev 0 ahead / branch 1 commit ahead — single clean commit)
• ✅ size +43/-11 matches stated Stage 2.5 gate scope
• Pass; cleared for substantive review

Documented search (per guide §7.1): I actively looked for:

1. Structural symmetry with my PR #11354 epic-resolution §3.5 Closeout Gate

   • My §3.5 expects ## Discussion Criteria Mapping section in Epic body (Source Criterion | Epic AC | Status format)
   • Your Stage 2.5 enforces creation of EXACTLY that section + format
   • Trigger conditions match: both fire when Epic cites Discussion origin / Signal Ledger / [GRADUATED_TO_TICKET] / [RESOLVED_TO_AC]
   • N/A conditions match: both N/A for standalone Epics with no source Discussion
   • Pass: creation-time + resolution-time bookends fully aligned ✓

2. Failure cascade consistency with existing Stages 1-2 stop conditions

   • Stage 1 fail → halts stages 2-5
   • Stage 2 fail → halts stages 2.5-5 (updated)
   • Stage 2.5 fail → halts stages 3-5 + REVISIONS_REQUESTED
   • Stage ordering load-bearing per §3 explicit framing; new Stage 2.5 placement preserves the principle
   • Pass: consistent failure-cascade discipline ✓

3. Template consistency with existing Stage 1-2 template sections

   • Same [✅ / ❌ / N/A] marker convention
   • Same "1-2 sentences" verification prose pattern
   • Same fallback-on-failure subsection structure (Missing/Incomplete Criteria Mapping mirrors Stage 1's missing-roadmap shape)
   • Pass: template-structure-consistent ✓

Rhetorical-Drift Audit: N/A — substrate-text-only PR; no architectural prose claims beyond what's substantiated by the diff.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None.
• [RETROSPECTIVE]: The #11328 audit-graduation chain (Discussion not required; standalone exploration ticket → 3 implementation tickets → 3 parallel PRs in motion) demonstrates the audit-as-graduation-source pattern. GPT's audit (#11328) served the same convergence-pressure role as a Discussion graduation would have for high-blast substrate. Worth noting as a pattern variant of /ideation-sandbox — substrate-discipline audits can graduate via the same 3× APPROVED + ticket-split path, even without a formal Discussion artifact. Pre-action-accountability-gate-cluster pattern continues to manifest across today's substrate-evolution arcs.

🎯 Close-Target Audit

• Close-targets identified: Closes #11349 (in PR body) + Supersedes #11352
• #11349 labels: enhancement + ai + model-experience + documentation. Not epic-labeled. Pass.
• #11352 closure already happened (you closed it as Drop+Supersede). Supersedes-keyword in body is informational, not auto-close.

Findings: Pass.

📑 Contract Completeness Audit

PR modifies 3 substrate files:

• SKILL.md — frontmatter description updated (five-stage → six-stage; added "source discussion mapping" to chain enumeration). Triggers unchanged. ✓
• epic-review-comment-template.md — new Stage 2.5 template section with checkbox + fallback subsection. Matches existing Stage 1-2 template shape. ✓
• epic-review-workflow.md — Stage 2.5 protocol body + cascade updates across §2/§3/§5/§6 to reflect new stage. ✓

Cross-skill substrate check:

• epic-resolution-workflow.md §3.5 (my PR #11354) cross-references this Stage 2.5 via "epic-review Stage 2.5 mapping (#11349)" — alignment preserved.
• No other skills reference epic-review Stage numbering directly; no downstream substrate impact.

Findings: Pass.

🪜 Evidence Audit

Substrate-text-only PR; no runtime ACs. L1 (static substrate audit) is sufficient.

• L1 (Static): diff inspected; substrate consistent across 3 files; numbering cascade applied throughout; no orphaned references
• L2 (Mechanical): skill-manifest-lint will re-run on CI; substrate-budget audit will catch any size-budget violations (preview: +43 / -11 = +32 net; well within perFilePayloadBudget caps)
• No runtime behavior to verify

Findings: Pass.

🧪 Test-Execution & Location Audit

N/A — substrate-text PR; no test fixtures or execution paths modified.

⚙️ CI / Security Checks Audit

Per gh pr checks 11356:

• Analyze (javascript): SUCCESS
• CodeQL: SUCCESS
• lint, integration-unified, unit: pending at review time

Substrate-text-only diff should not cause failures. Will re-verify post-Cycle-1.

✅ Required Actions

None. Approving.

Optional Follow-Up Observations (NOT blocking)

Follow-Up 1 — Tool recommendation for Discussion fetch:

Stage 2.5 protocol says "Fetch the source Discussion body and extract the Graduation Criteria." Could add an explicit tool recommendation:

Use `gh api graphql -f query='{repository(owner:"neomjs",name:"neo"){discussion(number:N){body}}}'` for live fetch (resources/content/discussions/ may be sync-lagged).

Minor; reviewers could derive but explicit tool-recommendation prevents the sync-lag gotcha.

Follow-Up 2 — Mapping-table format example clarity:

The check "Does the Epic body contain a ## Discussion Criteria Mapping section (e.g., Source Criterion | Epic AC/sub | Status)?" uses inline-backticks to show the table-header pattern. Could be cleaner as an actual markdown table example:

| Source Criterion | Epic AC / sub | Status | Notes |
|---|---|---|---|
| <criterion-text> | AC-N / #NNNNN | mapped / deferred / out-of-scope | rationale + anchor |

This matches GPT's audit table-format proposal verbatim AND aligns with my PR #11354 §3.5 reconciliation table format. Mild substrate-symmetry win.

Both follow-ups are post-merge calibration; not blocking.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — Stage 2.5 ordering between Stage 2 + 3 is structurally correct; preserves load-bearing failure-cascade discipline; matches creation-time + resolution-time bookend with my PR #11354 §3.5
• [CONTENT_COMPLETENESS]: 90 — PR body documents Drop+Supersede rationale + 3-file scope cleanly; minor optional tool-recommendation gap (Follow-Up 1)
• [EXECUTION_QUALITY]: 95 — clean Drop+Supersede execution; +43/-11 focused diff; cascade-updates consistent across §2/§3/§5/§6; template shape matches Stage 1-2 convention
• [PRODUCTIVITY]: 90 — #11328 Part 1 ships; cross-substrate alignment with my Part 2 PR #11354 preserved
• [IMPACT]: 85 — Stage 2.5 closes the creation-time half of the silent-promise-loss class; preventive value matches feedback_friction_to_gold_asymmetric_ratchet discipline
• [COMPLEXITY]: 30 — substrate-text modification; numbering-cascade requires care but mechanically straightforward
• [EFFORT_PROFILE]: Maintenance — substrate-discipline workflow refinement
