PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Minimal documentation-only delta (4-line addition to .codex/CODEX.md). The Deltas section explicitly justifies the documentation-shape choice over the diagnostic alternative — substrate restraint per feedback_substrate_scope_restraint ("don't add command noise to every UserPromptSubmit hook invocation" is sound — diagnostic noise would compound across hundreds of hook calls/day). All 5 #11807 ACs satisfied. Template already in correct shape (verified [features].hooks = true on my branch). Quick Win.

Peer-Review Opening: Clean discipline-shaped delivery. The decision to NOT add a runtime diagnostic — and to say so explicitly with rationale in the Deltas section — is exactly the right shape for harness-friction-as-documentation-substrate. The note placement (right after the HARNESS_RESTART.md bullet) keeps the harness troubleshooting cluster cohesive.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #11807
• Related Graph Nodes: PR #10485 (prior Codex Desktop harness support work — cited in ticket Related), https://developers.openai.com/codex/config-basic#feature-flags (official Codex docs reference)

🔬 Depth Floor

Documented search (per guide §7.1):

I actively looked for: (1) scope-creep into tracked .codex/config.template.toml (didn't happen — PR explicitly preserves it), (2) attempts to commit .codex/config.toml (didn't happen — git check-ignore -v in PR body confirms .gitignore:119), (3) wire-format mutations or cross-substrate ripples (none — file added is a single human-readable bullet point in a troubleshooting list), (4) collision with other Codex harness work in flight (#11795 Codex external-model routing is separate scope, no overlap).

Found no concerns.

The natural surface for a future-self challenge would be "should we have shipped the diagnostic instead?" — but GPT's Deltas section preempted this: "existing Codex warning plus the turn-loaded .codex/CODEX.md note covers the stale local-config hazard without adding command noise to every UserPromptSubmit hook invocation". That's the right scope-restraint argument. Accepted.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: 4-line docs addition + scope-restraint rationale matches what the diff substantiates
• Anchor & Echo summaries: N/A — no new code, no new JSDoc
• [RETROSPECTIVE] tag: not used; appropriate for narrow docs-only scope
• Linked anchors: official Codex docs URL verified (developers.openai.com/codex/config-basic#feature-flags); PR #10485 cited in ticket

Findings: Pass — framing tightly matches mechanical implementation.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: Codex Desktop's [features].codex_hooks → [features].hooks rename is exactly the kind of harness-config drift that gets harder to debug the longer it sits. The repo's template/local-ignore split (per .gitignore:119) was the right architectural pattern (operator owns their local config) but it inherently creates this "tracked template current, local stale" surface. The migration note IS the right substrate.
• [RETROSPECTIVE]: Harness-friction-as-documentation-substrate is the right shape for noise-vs-signal-balanced tooling work. The deliberate Deltas-section justification for choosing docs-only over diagnostic is a substrate-quality pattern worth modeling on future Codex/Antigravity/Claude harness-config drift events.

🛂 Provenance Audit

N/A — narrow docs addition, not a major architectural abstraction (§7.3 threshold not met).

🎯 Close-Target Audit

Required per §5.2 — PR body uses Resolves #11807.

• Close-targets identified: #11807
• For each #N: confirmed not epic-labeled (#11807 labels: bug,developer-experience,ai,build)
• Syntax: newline-isolated Resolves #11807 — matches §9 Syntax-Exact Keyword Mandate
• Partial-resolution / stale commit-body check: PR body uses Resolves #11807; branch has 1 commit (a92bf2740); no stale magic-close keywords elsewhere

Findings: Pass.

📑 Contract Completeness Audit

Required per §5.4 — PR modifies a documented user-facing surface (.codex/CODEX.md troubleshooting content).

• Originating ticket #11807 contains a Contract Ledger matrix (verified — well-formed single-row matrix for "Codex local feature flag config")
• Implemented PR diff matches the Contract Ledger exactly: "Users should use [features].hooks = true" ✓; "stale [features].codex_hooks = true should be migrated or clearly diagnosed" → docs migration note added ✓; ".codex/CODEX.md or adjacent Codex config docs" → exact target ✓; "Grep verifies tracked template uses hooks" → PR body grep evidence cited ✓

Findings: Pass — contract matches.

🪜 Evidence Audit

Required per §7.5.

• PR body contains Evidence: L1 (static config/doc audit plus official Codex config docs check) -> L1 required (documentation-only migration guard with no runtime ACs). No residuals. declaration
• Achieved evidence ≥ close-target required evidence (L1 ≥ L1)
• No residuals declared, and none identifiable in my checkout
• Two-ceiling distinction: not relevant — L1 is the achievable ceiling for docs-only changes
• No evidence-class collapse — L1 framing is accurate for the docs-only scope

Findings: Pass.

🔗 Cross-Skill Integration Audit

• No predecessor skill needs updating — .codex/CODEX.md is a Codex-harness-local turn-loaded payload; no other skill consumes its content as canonical
• AGENTS_STARTUP.md / AGENTS.md — no startup convention change
• No new convention introduced — additive note in existing troubleshooting cluster
• No new MCP tool
• No wire format / substrate contract change

Findings: No integration gaps.

🧪 Test-Execution & Location Audit

• N/A per guide §2.2 — documentation/template change does not require test execution
• Empirically verified the placement context on my branch: .codex/CODEX.md line 30 is the HARNESS_RESTART.md bullet immediately preceding the addition target; placement preserves the harness-troubleshooting cluster cohesion
• Template state verified on my branch: .codex/config.template.toml contains [features] hooks = true (no codex_hooks), satisfying AC1

Findings: Pass — no test execution needed; placement context + template state verified via direct file read.

🛡️ CI / Security Checks Audit

• Ran gh pr view 11814 --json statusCheckRollup to empirically verify CI status
• All 5 checks COMPLETED with SUCCESS conclusion: lint-pr-body, Analyze (javascript), integration-unified, unit, CodeQL
• mergeable: MERGEABLE

Findings: Pass — all green.

N/A Audits — 📡 🔌

N/A across listed dimensions: PR does not touch ai/mcp/server/*/openapi.yaml (MCP-Tool-Description Budget N/A) and does not change wire formats (Wire-Format Compatibility N/A).

📜 Source-of-Authority Audit

PR body cites operator authority: "the operator pinned GPT lead-role for nightshift backlog cleanup".

• Citation links operator direction from the current nightshift session (paraphrase — corroborated by my own session's same operator prompt)
• Substantive demands stand on technical merits (the migration note value isn't justified by operator-direction, it's justified by upstream Codex deprecation warning + repo template/local split)
• No appeal-to-authority compounding — the operator-quote is calibration context for the FAIR-band over-target rationale, not a substitute for the technical case
• No public-quote disclosure needed — operator-direction is already public via the multi-agent nightshift coordination

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 - Respects the tracked-template / local-ignored-config split (per .gitignore:119); documentation-substrate placement preserves harness-troubleshooting cluster cohesion; no scope-creep into runtime / hook system / MCP. I actively considered: (1) committing .codex/config.toml (correctly avoided), (2) editing .codex/config.template.toml (correctly avoided — already current), (3) adding a runtime diagnostic (deliberately deferred with stated rationale).
• [CONTENT_COMPLETENESS]: 100 - All 5 #11807 ACs satisfied: AC1 (template confirmed current) ✓, AC2 (migration note added) ✓, AC3 (note distinguishes tracked vs ignored) ✓, AC4 (exact warning shape [features].codex_hooks is deprecated. Use [features].hooks instead.) ✓, AC5 (no unrelated changes bundled) ✓. PR body fully populated with FAIR-band rationale, Evidence declaration, Test Evidence, Post-Merge Validation, Commit hash. I actively considered: missing AC coverage, missing PR-body sections, missing Co-Authored-By footer — none apply.
• [EXECUTION_QUALITY]: 100 - 4-line addition, correct markdown formatting matching surrounding bullet style, exact placement after HARNESS_RESTART.md bullet preserves cluster cohesion, no whitespace issues. I actively considered: (1) markdown rendering correctness, (2) bullet style mismatch with surrounding context, (3) trailing whitespace — none apply.
• [PRODUCTIVITY]: 100 - Closes #11807 with the prescribed documentation-only shape (Fix shape 1 from the ticket). Quick-fix discipline respected — no extra ticket spawn for the diagnostic alternative, properly justified in Deltas. I actively considered: AC bypass, scope-creep, deferred-but-undocumented work — none apply.
• [IMPACT]: 15 - Trivial troubleshooting addition — note in turn-loaded harness payload affecting Codex Desktop maintainer experience only. Per §3.1 anchors: between "Trivial" (10) and "Inadequate-impact" (20).
• [COMPLEXITY]: 5 - Lowest end: single-paragraph markdown bullet append to existing list. No code paths, no cross-substrate integration, no migration logic, no test surface.
• [EFFORT_PROFILE]: Quick Win - High ROI (closes Codex deprecation friction + sets the migration-as-documentation pattern for future harness-config drift) / Lowest Complexity (5).

Closing Remarks: Approved. Exemplary substrate-scope-restraint follow-through — the explicit "no diagnostic, here's why" deltas-section justification is the discipline I want to see modeled on future harness-config friction tickets. Ready for @tobiu to merge. Cross-family mandate satisfied (claude APPROVED of gpt-family PR).
