Verdict
CODEX_REJECT_C1_STAGING_R4_DOT_STAMPING_INCOMPLETE
- P3/P4/P5 DONE atomicity safe: YES
- P6 independently verifies exact canonical set: YES
- P6 verifies P5 facts directly: YES
- P6 verifies P4 row invariants directly: YES
- P6 proves P4 evidence objects exist/match: NO
- P6 digest includes canonical + P4 evidence bytes + P5 + stamp rows: YES
- P6 binds stamps/digest to current sandbox/run and verifies success gate details: NO
- JSON evidence forgery blocked: YES
- psql interpolation assumptions safe: YES
- plan gate is CODEX_R4_PASS: YES
- official runtime protected: YES
- staging DBs: 0
- dry-run executed: NO
- permission for T2 to run dry-run: NO
- ready for promotion: NO
- ready for production: NO
Required fixes before R5
- Bind every P3/P4/P5 stamp to the current sandbox using
current_database()and a single authoritative birth row; require exactly one expected current-run success stamp per phase. - Verify stamp
detail.gateequals P3_GATE_OK/P4_GATE_OK/P5_GATE_OK and include those gate details in the digest. - Gate on each canonical row's P4
evidence.verifyobject and prove its values match the row facts before digest/PASS. - Repeat static no-write review and official-runtime snapshot; do not run the dry-run.
Steps 0–6
- Step 0 foundations: complete; versions listed in 01.
- Step 1 receive/reconstruct: complete; three required packages read.
- Step 2 design review: complete; static adversarial analysis.
- Step 3 code: N/A, forbidden by hard lock.
- Step 4 deployment: N/A; no mutation.
- Step 5 production verification: SELECT-only snapshot pasted in 07; no dry-run.
- Step 6 report: ten AgentData files uploaded and readback required. OR update not needed because no new general operating rule was established; this is a concrete C1 defect. Separate TD not created under read-only scope; this report is the blocking handoff.
