Checkpoint — FIX7 Executable Approval Lane

• Date: 2026-06-10 · Object ID: TKT-OBJ-061 · provisional-non-authority, evidence-only · Codex: NOT consulted

Final status

FIX7_APPROVAL_LANE_PARTIAL_TRUE_BLOCKER — all safe T1 engineering delivered with a reproducible-from-KB Codex Recheck-9 packet; remaining gates are Codex/owner authority.

What changed (vs Recheck-8 NEEDS_T1_FIX)

• P1 DONE: .py materialized by reproducible byte-extraction → --selftest exit 0, 22/22, membership f2bda8…fe251 (cross-tool shasum==hashlib).
• P2 PARTIAL: production seal path built + run over 10 byte-exact docs → 6/8 aggregate digests as deterministic candidates + 10 per-doc; N7 rehearsal-only, N8 Codex-only.
• P3 DONE: selftest 22→36, covers production extractor + every fail-closed status.
• P4 DONE: runnable duplicate-authority inventory.
• P5 DONE: executable whole-doc extractor; clean over 10 real docs.
• P6/P7 = Codex: detached seal + re-seal (not T1).
• Reproducible packet built + verified runnable from KB (round-trip 36/36).

Self-check (§7)

1 SSOT-first ✓ · 2 claims inventoried ✓ · 3 5 lenses ✓ · 4 safe artifacts materialized not just listed ✓ · 5 every safe command run ✓ · 6 exit/log/hash captured ✓ · 7 selftest truthfulness tested ✓ · 8 all 8 digests addressed (6 produced, 2 precisely blocked) ✓ · 9 marker/extractor executable ✓ · 10 forbidden scope enforced ✓ · 11 duplicate prose authority removed ✓ · 12 checkable manifest ✓ · 13 Tool-Kiem-Thu lens applied honestly (no gate PASS) ✓ · 14 Codex recheck-9 packet reproducible ✓ · 15 new objects birthed ✓ · 16 cross-impact ✓ · 17 no production mutation ✓ · 18 no fake Codex/owner approval ✓ · 19 not stopped at punch-list ✓ · 20 verdict system-state-based ✓.

Article 13 PASS · Article 14 PASS · Production mutation NO · Codex NO · REAL_RUN/QT001/apply/permit/activation/repoint NO

Remaining blockers

B1 apply P-EXT-1 (owner/T1) · B2 N7 sealed inputs (Codex/owner) · B3 N8 detached seal (Codex) · B4 P7 re-seal (Codex) · B5 owner do-not-approve.

Minimal safe next step

Apply validated patch P-EXT-1 to the SSOT .md (1 reversible edit), then route the reproducible packet to Codex Recheck-9.

Verdict

CHECKPOINT_FIX7_EXECUTABLE_APPROVAL_LANE_PARTIAL_TRUE_BLOCKER — Codex-recheck-9 packet ready and reproducible; engineering complete; Codex/owner seal handoff remains.
