FIX7 P0 - Final Codex Executable Review Capsule - Report (2026-06-12)

Macro: FIX7_P0_FINAL_CODEX_EXECUTABLE_REVIEW_CAPSULE_AND_HANDOFF_READINESS_MACRO_2026_06_12 Host: T1 OR T2 / CLEAN TERMINAL Final status: FIX7_P0_CODEX_EXECUTABLE_CAPSULE_READY_FOR_AUDIT

Production mutation: NO. Production DB/Directus/live contact: NO. REAL_RUN/QT001/cutover/permit/activation/repoint: NO. CI trigger: NO. Secrets changed or copied: NO. Real production data copied: NO. Real-data/production decision selected: NO (default HOLD_REAL_DATA untouched).

What this lane did

Closed the exact Codex blocker CODEX_FIX7_P0_FINAL_PRE_REAL_DATA_READINESS_AUDIT_BLOCKED (raw_byte_executable_packet_materialized = false; 9/9 primary final-readiness artifacts absent from the Codex workspace) by materializing a LOCAL, self-verifying, executable raw-byte review capsule that Codex can read and rerun WITHOUT MCP/KB dependency.

Capsule (proven, tested path)

Path: /Users/nmhuyen/Documents/Manual Deploy/web-test/codex_review_evidence/fix7-p0-final-pre-real-data-readiness-2026-06-12/
pwd at self-test: capsule root; test -d for web-test, codex_review_evidence and the capsule root: ALL PASS.
File count: 207 (200 sealed in HASH_MANIFEST.txt + manifest + tree + 4 logs + 1 regenerated probe-results JSON).
Capsule tree: packet_tree.sha256 = d1cc08748b0231730111447c0bb1e7d6836dbd71e1c206b9a90adc06af0bac7e = sha256(HASH_MANIFEST.txt raw bytes), verified.
Root files: README_FOR_CODEX.md, REQUIRED_READ_ORDER.md, EVIDENCE_PATH_MAP.json, EXPECTED_HASHES_AND_TREES.json, CODEX_AUDIT_INSTRUCTIONS.md, VERIFY_CAPSULE.sh, RERUN_ALL.sh, HASH_MANIFEST.txt, packet_tree.sha256, manifest.json - ALL present.
Dirs: reports/ packets/ scripts/ fixtures/ bad_inputs/ expected_outputs/ governance/ authority/ decision/ ci_gate/ logs/ - ALL present.

Raw-byte sources (all verified BEFORE copy, re-verified after copy)

capsule packet	files	tree (recorded == recomputed)
final readiness packet	24	`b476b547...cd90`
CI seal-vs-bytes adoption packet	20	`b22c08d0...26d63`
rollback-validator hardening packet	9	`59788d04...e20e4`
no-production execution packet	20	`72b24b8a...87bb2`
production scoping packet	14	`154e6ff1...465c`
rehearsal-only rollback packet	21	`7a9364c5...47f9`
shaped-clone + CI-gate packet	19	`2fa3d54e...46da`
N7/N8/P7 authority seal packet	17	`3890cd34...a234`

Governance: post-fold canonical bytes byte-equal to KB rev26/25/117 pins (93abf50d... / a6926f8e... / d1d5e7d7...), chain of custody in governance/GOVERNANCE_PROVENANCE.md. Validator e6547e69...956c47 (18172 B) present 5x byte-exact. Surrogate fixture sha256 5a6ad463...f598 equals the sealed db_sha256_at_generation; marker GENERATED_SURROGATE_NOT_REAL_PRODUCTION_DUMP enforced in-DB. Only KB-resident prior-lane packet NOT copied: the 06-11 implementation-planning packet (tree f470d0d0...), not required for the final readiness audit question; documented in EVIDENCE_PATH_MAP.json not_in_capsule.

Executable proof (fresh shell, logged in capsule logs/)

command	exit
`bash VERIFY_CAPSULE.sh` (12 checks: root/files/dirs/manifest-parse/status-strings/hash-trees/no-real-data/no-secrets/HOLD/no-token-grant/exec-bits/bad-input-evidence)	0 - PASS
`bash RERUN_ALL.sh` (13 steps: 8 packet reruns + validator selftest + capsule probes + governance fold check + decision HOLD check + post-rerun seal integrity)	0 - PASS
`python3 -m json.tool` manifest.json / EVIDENCE_PATH_MAP.json / EXPECTED_HASHES_AND_TREES.json	all PARSE_OK

Logs: logs/selftest-commands.log, logs/verify-capsule.log, logs/rerun-all.log, logs/json-parse.log.

Bad-input proof

Capsule-level bad_inputs/capsule_bad_input_probes.py: 10/10 fail-closed, 0 forbidden-token leaks (production-execution/REAL_RUN/QT001/cutover requests refused; surrogate-claimed-as-real refused; no-mutation rollback refused by the hardened validator gate; CI byte drift, missing-file manifest and same-length hash mismatch all exit non-zero through the real CI gate; tampered decision packet selecting production fails the HOLD check). Plus the sealed lane probes (12/12), hardening probes, scoping probes (9/9) all rerun PASS inside RERUN_ALL.

PRODUCTION_ONLY_SKIP (documented; NOT engineering gaps)

Real-production-data clone rehearsal - needs an operator-provided secret-free isolated REAL-data dump + separate owner/GPT authorization (spec: decision/fix7-p0-operator-real-data-clone-handoff-if-required-2026-06-12.md).
Production execution / REAL_RUN / QT001 / cutover / CI deploy - forbidden surfaces, not selected by any decision document.

Codex next instruction

Exact instruction (verbatim in CODEX_AUDIT_INSTRUCTIONS.md and in the KB Codex prompt doc): run the audit ONLY from the capsule path above, no MCP, no KB prose; first commands cd <capsule>; pwd; find . -maxdepth 2 -type f | sort | sed -n '1,80p'; bash VERIFY_CAPSULE.sh; bash RERUN_ALL.sh; answer whether FIX7_P0_READY_FOR_REAL_DATA_DECISION is independently verifiable from the capsule; allowed statuses CODEX_FIX7_P0_EXECUTABLE_CAPSULE_AUDIT_PASS / _REJECTED / _BLOCKED_BY_CHANNEL.

Governance

New objects TKT-OBJ-520..530 reserved in a STANDALONE addendum, APPLY_NOW=NO, above the 508..519 addendum; canonical registry (rev26/25/117, max 507) UNTOUCHED; no fold performed.
