Codex Review — RS5B-CLOSEOUT-PATCH2 LEGO Readiness Seal — 2026-06-21

STATUS: PASS_WITH_CAVEATS REVIEW VERDICT: ACCEPT_RS5B_CLOSEOUT_PATCH2_LEGO_READINESS_SEAL Stop state: RS5B_CLOSEOUT_PATCH2_ACCEPTED_LEGO1_READY_FOR_PLAN_REGISTRATION_HOLD Registration gate: REGISTRATION_HOLD REGISTRATION_CAN_PROCEED = NO P2 status: CLOSED · NOT_OPENED · NOT_AUTHORIZED Named-lane status: NONE_OPENED LEGO readiness meaning: READY_FOR_PLAN_ONLY · NOT_READY_TO_WRITE Evidence tier: AgentData KB contract-only review · NO_CODEX_LIVE_READ · NO_RUNTIME_VERIFICATION.

1. Source Register

Codex read the controlling sources directly from AgentData KB in the main process:

  1. Operating Rules SSOT: knowledge/dev/ssot/operating-rules.md, v7.58 returned by direct search_knowledge.
  2. Constitution: knowledge/dev/laws/constitution.md, v4.6.3 BAN HÀNH returned by direct search_knowledge.
  3. Prior official Codex PATCH1 HOLD: revision 1, content_length 14085, truncated=false.
  4. PATCH2 index: revision 1, content_length 4797, truncated=false.
  5. PATCH2-01 source/HOLD reconstruction: revision 1, content_length 11358, truncated=false.
  6. PATCH2-02 complete RBP oracle/I6: revision 1, content_length 10075, truncated=false.

  16. PATCH2 macro rollup: revision 1, content_length 9214, truncated=false.

All governed target documents and the prior HOLD were read from AgentData KB. No chat summary, local mirror, or read-unblock digest was used as controlling evidence.

2. Package Completeness

PASS. AgentData inventory contains the required twelve files under knowledge/dev/laws-new/reports/rs5b-closeout-patch2/ plus the reports-level rollup. Every file is revision 1 and non-empty. The package is additive.

Job A remains accepted and is not reopened. The accepted dependency-safe rollback patterns, E1–E8 graph, C7 conditionality, and Gate A/Gate B inputs remain intact except for the explicitly superseded predicate and wording defects.

3. Blocker Closure B1–B9

Blocker Assessment Evidence
B1 PASS omits ¬RBP1 CLOSED Complete ¬RBP0…¬RBP10 formula
B2 no explicit I6 predicate CLOSED RBP-8 forward-fail-closed violation
B3 XBI-13 precedence conflict CLOSED 13A→RBP-2; 13B→RBP-4
B4 XBI-14 multi-outcome CLOSED 14A→RBP-3; 14B→RBP-5
B5 XBI-19 multi-outcome CLOSED 19A→RBP-10; 19B→RBP-5
B6 unsafe-successor fixture absent CLOSED XBI-26→RBP-8
B7 C2 weakening fixture absent CLOSED XBI-27→RBP-6
B8 I5 excludes C2 CLOSED C2 coverage corrected to I5=required
B9 Gate B wording contradiction CLOSED Five-part sealed wording

No prior blocker remains open at the declared contract-classifier level.

4. Complete RBP Oracle

PASS. The controlling closed set now contains eleven reject predicates plus PASS:

  • RBP-0 runtime mutation;
  • RBP-1 plan absent;
  • RBP-2 referenced identity deleted;
  • RBP-3 dependency orphaned;
  • RBP-4 history erased;
  • RBP-5 historical semantics changed;
  • RBP-6 prior or forward authority weakened;
  • RBP-7 successor rule absent;
  • RBP-8 successor exists but forward path is not fail-closed;
  • RBP-9 audit trail absent;
  • RBP-10 rollback non-local;
  • RBP-PASS review-only validity.

The controlling formula is complete:

ROLLBACK_CONTRACT_VALID_FOR_REVIEW ⇔
¬RBP0 ∧ ¬RBP1 ∧ ¬RBP2 ∧ ¬RBP3 ∧ ¬RBP4 ∧
¬RBP5 ∧ ¬RBP6 ∧ ¬RBP7 ∧ ¬RBP8 ∧ ¬RBP9 ∧ ¬RBP10

Plan absence, destructive rollback, authority weakening, unsafe successor, unauditable rollback, and non-local rollback cannot reach PASS. PASS remains necessary-not-sufficient and grants no execution authority.

5. I6 Assessment

PASS. I6 now maps directly to RBP-8 ROLLBACK_FORWARD_FAIL_CLOSED_VIOLATED.

The discriminator Q separates:

  • no successor rule → RBP-7;
  • successor exists but retired value remains admissible → RBP-8;
  • successor exists and retired value is rejected for new use → neither, continue evaluation.

XBI-26 proves the PATCH1 fail-open input now rejects before PASS.

6. Predicate and Precedence Assessment

PASS. RBP-2/RBP-3/RBP-4 are separated by what survives:

  1. identity missing → RBP-2;
  2. identity exists but edge cannot resolve → RBP-3;
  3. identity and edge resolve but evidence payload is unreadable → RBP-4;
  4. reference and payload exist but meaning changed → RBP-5;
  5. authority requirement reduced → RBP-6.

The hash-deletion counterexample now returns RBP-2, consistent with precedence. No explanatory prose overrides the classifier order.

RBP-6 and RBP-8 may describe adjacent forward failures, but precedence and predicates distinguish authority reduction from retired-value admissibility. PASS is independent of precedence because any reject match falsifies the complete conjunction.

7. XBI Assessment

PASS. The required fixtures are single-input/single-code:

  • XBI-13A/B distinguish identity deletion from payload erasure.
  • XBI-14A/B distinguish orphaned reference from changed meaning.
  • XBI-19A/B distinguish non-local equivalent rewrite from meaning-changing rewrite.
  • XBI-26 covers present-but-unsafe successor.
  • XBI-27 covers forward C2 authority weakening.

Every fixture states one input, one expected code, tested invariant, no-competing-code explanation, no PASS/seal/digest, and REJECTED. The prior multi-outcome fixtures are explicitly superseded.

Classifier totality remains scoped to declared contract inputs, not arbitrary malformed serialization or runtime implementation.

8. C2 / I5 Assessment

PASS. C2 is now directly subject to I5 because C2 controls which authority references are required in authorization_binding_digest.

A successor C2 schema cannot silently drop or optionalize:

  • owner scope/head;
  • authority policy;
  • founding authority;
  • approval_mode;
  • approval/quorum/principal evidence when approval is used;
  • nonce/window evidence where replay policy requires it.

Forward weakening yields RBP-6. Old packets remain readable under their original protocol version. Any separately governed authority-policy transition remains a separate authorized act and cannot be smuggled in as schema rollback.

9. Gate B Wording

PASS. The controlling distinction is now unambiguous:

  1. this PATCH2 package does not open P2;
  2. Gate A does not open P2;
  3. only a future, actually satisfied Gate B may authorize the named P2 design/build lane;
  4. Gate B does not authorize registration, activation, real register_dot, P3, rollback execution, or ungated runtime writes;
  5. no Gate B is satisfied by this package.

No Chairman token, carrier-specific plan, current preflight, or named-lane authorization is asserted to exist.

10. LEGO #1 Readiness Seal

PASS_WITH_CAVEAT. L1–L7 provide proof source, attack, expected rejection, and status for identity, dependency edge, rollback, tests, gates, authority, and non-overclaim.

The seal is accepted only with this controlling interpretation:

  • it certifies the baseline criteria/template are coherent enough to prepare a future carrier-specific Gate B plan;
  • it does not establish that a concrete first carrier already has a selected name, stable runtime ID, or version;
  • no C1–C7 carrier is selected as “first”;
  • no carrier is created;
  • no P2 or named lane opens;
  • no write or rollback is authorized.

Thus LEGO1_ASSEMBLY_READY_FOR_GATE_A_BASELINE means ready-for-plan only. L1’s “name/purpose/stable ID/version” is a requirement for the future plan, not evidence of an already instantiated carrier.

11. Adversarial Self-Review

PASS_WITH_CAVEAT. A1–A14 and A16–A19 correctly reject their invalid inputs before PASS. A15 is a positive scope-control case: a hypothetical satisfied Gate B returns the legitimate named-lane-only output while refusing registration/runtime authority. It is not itself a reject-code fixture. A20 is a registration-gate assertion rather than an RBP code fixture.

The package’s phrase “every A1–A20 is rejected and single-coded” is therefore read narrowly: every invalid escalation is blocked; A15 verifies bounded positive output, and A20 verifies no hold-clearing transition exists. This editorial precision does not create a fail-open path.

No invalid input reaches PASS, seal, authority token, registration-ready output, runtime mutation, or rollback execution.

12. Scope and Non-Overclaim

PASS. PATCH2 performs and authorizes none of the following:

  • P2 opening or named-lane opening;
  • runtime mutation or DDL/DML;
  • rollback execution;
  • Chairman authorization existence;
  • Owner/scope/APR/register_dot/approval/handler creation;
  • canonical-operation runtime rows;
  • registrar/validator patch or RS-VALIDATOR;
  • implementation, registration, or activation.

Package “0 mutations” remains an attestation, not independent live verification.

REGISTRATION_HOLD remains active. REGISTRATION_CAN_PROCEED = NO. P2 remains closed.

13. Accepted Points

  1. Complete additive package.
  2. B1–B9 closed at contract level.
  3. PASS formula complete.
  4. I6 has a dedicated predicate and fixture.
  5. Predicate definitions and precedence agree.
  6. XBI fixtures are single-input/single-code.
  7. C2 forward schema evolution is covered by I5.
  8. Gate B wording is sealed.
  9. LEGO readiness is bounded to readiness-for-plan.
  10. Job A and accepted carrier patterns are not reopened.
  11. Registration HOLD and all carried blockers remain.
  12. No runtime or execution authority is inferred.

14. Rejected or Overclaimed Points

  1. Rejected: LEGO readiness means a carrier is selected, instantiated, or ready to write.
  2. Rejected: Gate A or this acceptance opens P2.
  3. Rejected: Gate B authorizes registration/runtime without later separate gates.
  4. Rejected: oracle PASS authorizes rollback execution.
  5. Rejected: design fixtures are executed runtime proof.
  6. Not independently verified: package zero-mutation and runtime-state attestations.
  7. Editorial caveat: A15 is a positive control, not a rejected bad input; A20 has no dedicated RBP code.

15. Final Verdict

VERDICT: ACCEPT_RS5B_CLOSEOUT_PATCH2_LEGO_READINESS_SEAL

The rollback-validity oracle is now complete and internally consistent for its declared contract domain. B1–B9 are closed: plan absence participates in PASS, I6 has RBP-8, precedence and fixtures agree, C2 schema evolution cannot weaken authority silently, and Gate B’s named-lane scope is explicit.

The LEGO #1 readiness seal is accepted strictly as readiness-for-plan. It does not select or create a carrier, open P2, authorize a named lane now, permit runtime mutation, or clear any registration prerequisite.

Stop state: RS5B_CLOSEOUT_PATCH2_ACCEPTED_LEGO1_READY_FOR_PLAN_REGISTRATION_HOLD.

Single next step: the corrected closeout may serve as the Gate A baseline for preparing a future carrier-specific Gate B plan. Any Gate B evaluation remains a separate future review requiring named carriers, dependency-safe rollback proof, current read-only preflight, exact-scoped Chairman authorization, and independent plan acceptance.

REGISTRATION_HOLD remains active. REGISTRATION_CAN_PROCEED = NO. P2 remains CLOSED, NOT_OPENED, and NOT_AUTHORIZED. NO NAMED LANE IS OPEN.

DO NOT IMPLEMENT: Confirmed. No runtime mutation, DDL/DML, P2 or named-lane opening, rollback execution, Owner/scope/principal/APR/approval/register_dot/handler, runtime row, registrar/validator patch, RS-VALIDATOR, implementation, registration, activation, or blocker resolution was performed or authorized.

16. Three Declarations and Compliance

  • Permanent: one closed predicate system governs rollback validity; precedence and fixtures agree.
  • Mistake-resistant: every declared invalid rollback falsifies at least one explicit PASS conjunct.
  • 100% automatic: not yet a runtime claim; the contract is ready to translate into future plan-specific tests, but no executable implementation exists.

Assembly Gate: PG/Directus/Nuxt = N/A; AgentData KB contract-only review. Data flow: direct AgentData reads plus one official Codex report write. OR/TD/handoff update is not required because no runtime or implementation state changed.
