🔍 Cross-Review: Codex CLI Agent Integration & v4.2.0 Bump (Job 9cc33e22)

• Reviewer: reviewer-opencode-01 (role: reviewer)
• Target: Branch support-codex working tree implementing plan-e30e3123.md Rev.2 (the Codex 6th-agent integration + v4.2.0 MINOR bump): 34 modified + 2 new files, 46-point wiring table, plus the plan documents.
• Method: Every plan claim re-verified against live source, the live codex CLI (0.153.4) on this machine, my own test runs (full 462-test suite), and my own re-execution of the challenge-critical regex. Peer verdicts (Claude PASS 36148213, Grok NOT PASS 5bfd80b8) checked against primary evidence — they conflict, and I resolved the conflict myself.

1. Codex implementation — verified correct (multi-layer)

My verification runs:

Check	Result
bash -n all 6 touched shell scripts + py_compile codex.py	OK
pytest tests/test_version_consistency.py	2 passed — lockstep at 4.2.0
pytest tests/test_a4_adapter_contract.py	29 passed (was 25; +4 codex)
Full suite pytest tests/ -q	462 passed / 0 failed (955s, my own run) — 455 prior + 7 new codex tests
Collect-only	462 tests — count matches

Adapter (codex.py, 158 lines): matches the Rev.2 plan sketch exactly — state_*.sqlite glob with mtime-max (no hardcoded suffix, per the accepted challenge refinement), DB-first/glob-fallback rollout resolution, verify_artifact using the DB row's cwd when available, purge_artifacts shelling codex delete <uuid> --force first with manual file+DB-row fallback, Class A spawn/resume specs (--dangerously-bypass-approvals-and-sandbox). The facts bridge emits the exact contract values.

Live CLI ground truth (this machine): codex-cli 0.153.4 confirmed; ~/.codex/state_5.sqlite exists with the exact threads(id, cwd, rollout_path) schema and 2 real rows matching the 2 real rollout JSONL files — the plan's §1.5 dual-layer storage description is accurate, and the adapter's DB-first order mirrors Codex's own reconciliation literals.

Flag-tolerant regex (challenge item 1): I re-ran both regexes myself against codex resume --dangerously-bypass-approvals-and-sandbox <uuid> — Rev.1's regex returns empty (exit 1, defect confirmed), the landed regex correctly extracts the UUID (exit 0). The regression test test_orc_onboard_codex_flag_tolerant_regex locks it down, and the wiring landed at orc_onboard.sh:133-135 exactly as planned.

Wiring spot-checks (from the 46-point table): lib.sh kind mapping (*-creator-codex), send_keys_safe _sks_agent="codex", create auth preflight (line 136), FRESH_SPAWN Class A arm (resume_session.sh:65), stop capture (codex_session_id_own = captured), reconcile drift-C codex block (state-DB-first with a schema-tolerant order-column PRAGMA check — a defensive improvement beyond the plan), status.sh codex branches in both formatters — all present and correct. Class B (claude/grok) paths untouched.

SemVer v4.2.0 MINOR: correct — new agent backend = the v4.1.0 (opencode) precedent exactly. Lockstep complete (lib.sh:32, VERSIONS.md header/date/matrix/changelog, 8× SKILL.md at 4.2.0), and the header's 기준 브랜치: support-codex honestly reflects the working branch.

2. The blocking defect — prior-art clobbering at .agents/reports/implementation_plan.md

Grok (5bfd80b8, NOT PASS) flagged this; Claude's PASS (36148213) did not address it. I independently confirmed Grok is right:

• HEAD's .agents/reports/implementation_plan.md is the full OpenCode Rev.3 plan (249 lines, tracked since the v4.1.0 integration) — the executed rationale for the opencode backend that shipped.
• The working tree replaces it wholesale with the Codex Rev.2 plan (391 lines).
• The Rev.3 changelog's own convention says the plan is "permanently housed under plan-de667f0f.md and mirrored at implementation_plan.md" — but plan-de667f0f.md is only a 16-line stub report pointing at the mirror. The mirror was the only full copy; this change deletes it from the tree.
• Verified: no working-tree file contains the OpenCode Rev.3 full text (grep for its title across all .md — empty). Git history retains it, but the durable named path loses it.
• This is the same 유실/prior-art-clobbering class as the aca0b7e8 round (v4.0.0 consensus artifact) and job 56120ad3's F1 (OpenCode Rev.2 overwrote the root NATS plan) — a recurring failure mode this session has rejected every time.

Required fix (mechanical, not design-level — Grok's proposed remediation is correct and I concur):

1. Restore the full OpenCode Rev.3 into the namespaced path: git show HEAD:.agents/reports/implementation_plan.md > .agents/reports/planner-reviewer-claude-01/plan-de667f0f.md (optionally with a 2-line header noting the mirror now holds the Codex plan).
2. Keep the Codex plan at both implementation_plan.md and plan-e30e3123.md (that pairing is correct).
3. Update the Codex plan's Status line ("Plan only — no code changed in the repo") — it now contradicts the tree, which contains the full implementation.

Notably: Claude is the author of both plans (the overwritten Rev.3 and the overwriting Rev.2) and its PASS review focused on the code wiring (which is genuinely correct) but did not examine the archive-path loss. Grok's review is the one that checked the durable-paths claim — and its finding survives my independent verification.

3. Secondary observations (non-blocking)

• Claude's PASS also flagged (correctly, in its §"self-report citations") that the Worker's self-report contains several wrong file:line citations — the code is right but the report's citations don't all check out. Worth fixing for the record but not blocking.
• conftest.py's codex mock seeds state_5.sqlite with a fixed name — fine for a hermetic sandbox (the adapter globs state_*.sqlite, so any name works); no portability concern.
• The drift-C codex block's schema-tolerant PRAGMA table_info order-column detection is more defensive than the plan required — a good hardening against Codex's evolving schema.

4. Verdict

The Codex integration itself is exemplary: plan verified against live CLI facts, the challenge round caught a genuine regex defect (now fixed, regression-locked, and re-verified by me) and a genuine storage-layer gap (now handled with DB-first resolution and CLI-owned purge), the 46-point wiring is complete and correct, Class B contracts untouched, lockstep holds at 4.2.0, and the full suite passes 462/462 in my own run. But the diff also clobbers the tracked OpenCode Rev.3 plan from its only full-copy durable path — a prior-art 유실 defect of the same class this session has consistently rejected, confirmed by me from primary evidence and not addressed by the plan author's own review. It is mechanically fixable (restore Rev.3 to its namespaced path, keep the Codex pairing, sync the Status line) without touching any code.

[VERDICT: NOT PASS]
