10 - Final Verdict

Final status

FIX7_REFACTOR_BLUEPRINT_T1_PATCHED_FOR_OPTION_BETA_READY_FOR_CODEX_RECHECK_3

Summary

Codex (design owner) approved Option Beta for the blocker-C legacy-disposition amendment. T1 patched the FIX7 refactor execution blueprint to that ruling: the legacy-disposition model is removed and replaced by a single uniform authority-neutralized end-state for every member of a closed, sealed U_legacy set, carried entirely by approved primitives (PG ownership isolation + sealed #20 protected_target roots + exact #11 closure + closed-world sealed #21 + #26/#27 + manifest activation). No production mutation; no hardcode introduced; the read path was open throughout.

Per-blocker verdicts

amendment blocker verdict
1 remove legacy-disposition model completely DONE (doc 02)
2 redefine U_legacy under Option Beta DONE (doc 03)
3 remove STUB / body-mutation path DONE (doc 04)
4 owner isolation + #21 privilege contract as the authority path DONE (doc 05)
5 remove DO_NOT_TOUCH as authority exclusion DONE (doc 06)
6 hardcode / PG-native self-review PASS (doc 07)
7 cross-layer boundaries CONFIRMED unchanged (doc 08)

Dimension verdicts

  • Disposition-model removal: REMOVED — no enum, LEGACY_* row, classifier, truth table, CASE branch, external-artifact policy, STUB/body path, DO_NOT_TOUCH subtraction, or relkind/prokind/ name/owner/pattern/label policy; former labels are non-authority English only (G-LEGACY-NO-DISPOSITION-AUTHORITY).
  • U_legacy uniform end-state: PASS — single sealed set closure(#11, roots=#20 protected_target rows), no subtraction, collisions fail closed; every member owner-isolated + body unchanged + effective privileges == exact sealed #21 (G-U-LEGACY-OPTION-BETA-UNIFORM-ENDSTATE).
  • STUB / body-mutation removal: REMOVED — no body change/restore anywhere; forward-only rollback restores owner+ACL from the single S14 snapshot; source artifacts evidence only.
  • Owner isolation / #21 contract: PASS — owner-transfer to unreachable qt001_cp_owner + closed-world #21 both-EXCEPT is the authority path; G-NOLEGACY-POST verifies the uniform end-state.
  • DO_NOT_TOUCH authority removal: PASS — boundary/hard-block label only; never subtracts; collisions fail closed.
  • Hardcode / PG-native: ZERO_HARDCODE_PASS / PG_NATIVE_DRIVEN_PASS (doc 07, 12/12 checks).
  • Cross-layer: PASS — implementation/2.6B/QT001-apply/permit/REAL_RUN/activation/repoint/cutover BLOCKED; governance/registry-pivot/Đ43/harness later; runtime evidence non-authority.

Invariants (preserved)

AUTHORITY_SURFACES=27 · RUNTIME_EVIDENCE=11_NON_AUTHORITY · READINESS_GATES=14_DATA ·
HASH_CONTRACTS=7_H01..H07 · NEW_AUTHORITY_SURFACE=0 · NEW_#20_COLUMN=0 · NEW_CATALOG_FAMILY=0 ·
NEW_READINESS_GATE=0 · NEW_TOP_LEVEL_HASH_CONTRACT=0 · TEST_GUARDS=42 (40→42) · PRODUCTION_MUTATION=0

Why this status (not the others)

  • Not ..._OPTION_BETA_PATCH_NEEDS_MORE_T1_WORK: every amendment blocker (1–7) is patched in-blueprint against approved primitives; the disposition model is fully removed; the uniform end-state and its guards are in place; no residual T1 gap remains.
  • Not ..._OPTION_BETA_PATCH_FAIL_HARDCODE_OR_PG_NATIVE_GAP: the patch removes (does not add) the disposition/CASE/label/name-pattern/STUB/external-artifact constructs; authority is PG-native (ownership + sealed #20/#11/#21 + #26/#27 + activation); the self-review (doc 07) is clean.
  • Not READ_PATH_BLOCKED: the Option-Beta amendment package, the recheck-2 patch, the current blueprint, the design-approval source, and the prior live pg_roles evidence were all readable read-only.

Boundaries

Official FIX7 design remains approved. The blueprint and implementation-authoring planning are NOT approved — the next gate is Codex recheck 3 of this Option-Beta-patched blueprint. Implementation, Stage 2.6B, qt001_backfill_permit, REAL_RUN, QT001 apply, manifest activation, repoint, and owner/ACL cutover all remain BLOCKED. Production was READ-ONLY throughout this pass (no fresh live read required); no object was created, altered, owned, granted, revoked, or executed. The only writes were the eight blueprint-doc revisions (02/03/04/05/06/07/08/12), this report (00..10), and the two checkpoints.

Do not claim implementation approval. Next is Codex recheck 3 only.
