FIX7 Executable Approval Lane — Master Report

• Date: 2026-06-10 · Macro: PROGRAM_MACRO_CLOSE_FIX7_EXECUTABLE_BLUEPRINT_APPROVAL_LANE_WITH_TOOL_KIEM_THU · Object ID: TKT-OBJ-051
• Authority: provisional-non-authority, evidence-only, decision_effect=NONE, may_gate=false. Codex = sole sealer; owner "do not approve" preserved.
• Codex consulted: NO · Production mutation: NO · REAL_RUN/QT001/apply/permit/activation/repoint/cutover: NO · auto-birth repair: NO · registries-pivot: NOT resumed.
• Reproducible packet: …/packets/fix7-codex-recheck-9-2026-06-10/ (README_FOR_CODEX, manifest.json, runnable code, hash manifest, rerun, raw logs) — verified runnable from KB (36/36 PASS round-trip).

1. Mission outcome (system state)

Took the FIX7 construction blueprint from Codex Recheck-8 = NEEDS_T1_FIX (5 Article-14 executable-evidence defects, single-rooted at an absent runnable .py) to: all safe T1 engineering delivered with reproducible executable evidence; the remaining gates are Codex/owner authority, not engineering.

Final status: FIX7_APPROVAL_LANE_PARTIAL_TRUE_BLOCKER — the reproducible Codex Recheck-9 packet is complete and Codex-recheckable; the lane cannot reach PASS because the detached seal (N8), the manifest's sealed inputs (N7), the Codex re-seal (P7), the one-step apply of validated patch P-EXT-1 to the SSOT, and the owner's standing do-not-approve are all non-T1 authority actions.

2. SSOT readback verdict

14-doc blueprint + canonicalizer .md + Codex Recheck-8 + Tool-Kiem-Thu check report read first-hand (KB-first). Decisive readback: the canonicalizer .md does contain a complete, self-contained, stdlib-only Python program (the recheck-8 fence) whose selftest reproduces membership=f2bda8…fe251 but does NOT read doc content or compute the other 7 digests. No .py file existed. The 7 non-membership digest encodings are precisely specified in doc 00 (NON_AUTHORITY_EXPLANATION of the SSOT) — transcribable, not invented; all 7 values are SEAL_AT_CODEX_RECHECK_8 by design. No contradiction between this macro's findings and Codex Recheck-8 / the prior Tool-Kiem-Thu check.

3. Per-track results (20 tracks)

Track	Result
1 SSOT/readback	DONE — readback table in §2; 14 docs + recheck-8 + check report reconciled
2 Claim inventory	DONE — see fix7-executable-claim-ledger-2026-06-10.md (C-01..C-07 + 8 digest claims)
3 5-lens classification	DONE — L1/L2/L3 cleared structurally by P1; L4/L5 cleared by extended encoder + inventory
4 Materialize executable SSOT	DONE (P1) — .py materialized by reproducible byte-extraction; runs; exit 0; membership reproduced cross-tool
5 Remove duplicate authority	DONE — one implementation; extended code is single source (patch P-EXT-1); runnable dup-authority inventory added
6 Selftest hardening	DONE (P3) — 22 → 36 checks; exercises production extractor + every fail-closed status; real output pasted
7 Full pipeline digest reproduction	PARTIAL (P2) — 6/8 aggregate digests produced as deterministic candidates + 10 per-doc; N7 rehearsal-only, N8 Codex-only (precise blockers)
8 Marker/extractor enforcement	DONE (P5) — executable whole-doc extractor; ran clean over 10 real docs
9 Forbidden-scope enforcement	DONE — stdlib-offline-only; 0 forbidden ops; QT001/REAL_RUN/etc. mechanically absent
10 Package/manifest	DONE — machine-readable manifest.json binds artifacts/commands/exit-codes/hashes
11 Local non-production checks	DONE — all runs offline, exit codes + hashes + timestamps captured
12 Tool-Kiem-Thu lens	DONE — 5-lens re-applied; support evidence only, no gate PASS claimed
13 Negative/adversarial	DONE — tamper/missing/absent-py(exit2)/wrong-membership + 11 fail-closed fixtures
14 Blueprint/package patch	DONE as patch packet P-EXT-1 (validated, runnable); in-place apply deliberately gated
15 Codex Recheck-9 packet	DONE — reproducible (README/manifest/logs/hashes/rerun/negatives/forbidden/expected)
16 Governance / birth	DONE — TKT-OBJ-047..056 birthed in registry (md+json rev3)
17 Cross-impact	DONE — see cross-impact report; no parallel authority, no auto-birth touch, registries-pivot still blocked
18 Evidence persistence	DONE — packet + 14 deliverables under KB tool-kiem-thu paths
19 Roadmap/current-state	DONE — see roadmap doc
20 Final integrated verdict	FIX7_APPROVAL_LANE_PARTIAL_TRUE_BLOCKER (this report)

4. The honest reclassification (the core finding)

Recheck-8 said "7/8 seal digests blocked." After this macro:

• 6/8 aggregate digests are computable now and were produced deterministically (membership FROZEN + marker_fence_registry + superseded_boundary + guard_set as real candidates; active_corpus as a determinism-proven rehearsal with revision placeholders; candidate canonicalizer_sha256), plus 10 real per-doc content hashes.
• 2/8 are inherently seal/Codex-dependent — not "no code": N7 envelope_manifest binds sealed sub-digests + approval-event fields (approved_status/epoch/by_role/at_utc/parent_recheck_checkpoint) only Codex/owner set; N8 detached_seal is Codex-authored (sealed_by/at, signature, parent_checkpoint_id, report_documents[]). The blueprint's own rule confirms this: "T1 pre-writing approved content hashes would be self-fabricated authority."

So the absent-code blocker is fixed; what remains is the Codex seal handoff, which was never a T1 deliverable.

5. Article 13 / Article 14 verdicts

• Article 13 PASS — KB-first/PG-first/local-last honored; no production mutation; read-only KB except documented deliverable writes; no Codex/owner approval claimed.
• Article 14 PASS — the executable claim is now backed by a runnable artifact + pasted real output + reproducible rerun + hashes; no prose-only PASS; the checker pastes real evidence (does not commit the sins it detects); exactly one canonical implementation (no duplicate authority); the 7 unfrozen digests are NOT self-fabricated — they are produced as labelled candidates/rehearsals or precisely blocked on Codex.

6. Remaining blockers (true, non-engineering)

B1 apply patch P-EXT-1 to SSOT .md (owner/T1 visibility gate) · B2 N7 sealed inputs (Codex/owner) · B3 N8 detached seal (Codex) · B4 P7 Codex re-seal · B5 owner do-not-approve. See action-ready-blocker-after-fix7-executable-approval-lane-2026-06-10.md.

7. Minimal safe next step

Owner/T1 apply validated patch P-EXT-1 to the SSOT .md fence (1 edit; reversible KB revision), then route the reproducible packet to Codex Recheck-9 to seal N7/N8 and the candidate values.

Verdict

FIX7_APPROVAL_LANE_PARTIAL_TRUE_BLOCKER — every safe engineering branch executed and reproducibly evidenced; the FIX7 executable approval lane is at the Codex/owner doorstep with a complete, runnable-from-KB recheck-9 packet. Article 13 + 14 PASS. No production mutation, no Codex, no fake-green.
