13 — SELF-REVIEW FINAL GATE

Self-review verdict

CLAUDE_CODEX_STYLE_SELF_REVIEW_PASS All 11 matrix rows (file 11) are PASS; none HOLD/FAIL.

Would Claude reject its own patch? — NO (with a caveat)

Acting as a hostile reviewer, the strongest attacks I could mount were:

1. "P5 still counts any exception as pass." Refuted: the success branch hardcodes pass=false (accepted bad input = FAIL); the exception branch passes only on exact reject_code/SQLSTATE match; a FATAL DO gate raises unless 9/9·0fail·0accepted·residue=3.
2. "P6 can emit a digest without upstream." Refuted: the FATAL gate runs before the digest and PASS lines; ON_ERROR_STOP=1 aborts psql on any RAISE.
3. "User data still hits a shell." Refuted: psql is exec'd as argv ("$@"), no sh -lc/eval; values are psql -v literals; sandbox names are regex-validated before any interpolation.
4. "Cleanup can drop the wrong DB." Refuted: regex + off-limits list + active-registry + defense-in-depth assert; self-tests show directus/postgres/injection names refused.
5. "You secretly touched official runtime." Refuted: three identical snapshots; staging_dbs=0; only the staging tree's sha256 changed.

The single honest caveat (NOT a rejection): the exact runtime reject_code/SQLSTATE of the 9 P5 cases is statically derived + read-only-verified, with full runtime confirmation deferred to the Codex-R2-gated dry-run. Any mismatch fails CLOSED (abort), never a false PASS. This is the correct, fail-safe posture and does not warrant a HOLD verdict for a static patch macro.

Official runtime guard during self-review

No official runtime value changed during the self-review (snapshots in file 09/12). staging_dbs remained 0. No dry-run executed. The verdict C1_STAGING_SELF_REVIEW_FAIL_OFFICIAL_RUNTIME_MUTATED is NOT triggered.

Gate outcome

Because the self-review PASSES, the macro final verdict may be: C1_STAGING_CODEX_R1_FIXES_READY_FOR_CODEX_R2

• ready for Codex R2 review: YES
• ready to run dry-run without Codex: NO
• ready for promotion: NO
• ready for production: NO
