09 — FINAL VERDICT
Verdict
CODEX_REJECT_C1_STAGING_R3_EVIDENCE_FALSE_PASS_RISK
- Claude R3-SELF-1 fix valid: YES
- injection remains fixed: YES
- SBX propagation safe: YES
- P1 partial cleanup safe: YES for trappable failures
- plan cleanup target safe: YES
- P2 failure cannot be swallowed: YES
- --force disabled/provenance-safe: YES
- P5 fail-closed safe: YES
- P6 false-PASS blocked: NO — upstream pre-gate stamps can masquerade as DONE
- DOT stamp/ledger/evidence sufficient: NO
- official runtime protected: YES
- permission for T2 to run dry-run: NO
- ready for promotion: NO
- ready for production: NO
Required fixes
- Move P3/P4/P5 fatal gates before DONE ledger insertion and COMMIT, or write explicit success stamps only after gates.
- Require those success stamps in P6 and independently enforce the exact three expected operation codes plus field invariants.
- In plan cleanup, require P2 RETIRED_OK/drop_success for the owned sandbox; do not treat NO_OP as equivalent.
- JSON-encode dynamic host-ledger fields and verify appended JSONL.
- Refresh registry/ledger/evidence, rerun static no-write validation, then request the next external review.
Steps 0–6
0 foundations/search complete; 1 receive complete; 2 static design review complete; 3 code N/A by hard lock; 4–5 no deploy/dry-run/production mutation; 6 ten KB reports uploaded/read back. OR update not needed; findings apply existing fail-closed/evidence laws. No separate TD/handoff mutation under the read-only lock.
