RS5B-CLOSEOUT — Codex/GPT Review Packet — 2026-06-21

For: the next independent (GPT, then Codex) review of RS5B-CLOSEOUT-P2-ENTRY-SCOPING. Verdict under review: RS5B_CLOSEOUT_P2_ENTRY_READY_FOR_GPT_REVIEW (not forced). Gate: REGISTRATION_HOLD · REGISTRATION_CAN_PROCEED = NO · 0 mutations. This packet is self-contained but every claim is traceable to a KB source read directly (file 01).

---

1. Mission (one)

Two jobs, one package: (A) consolidate RS5B + PATCH1 + PATCH2 + Codex acceptances into one corrected-contract view at contract layer only; (B) define a future-only P2 entry gate. No P2 opened, no runtime touched.

2. What to verify

1. Direct-read discipline: file 01 records path/revision/content_length/truncated for all 18 sources (3 Codex + 8 RS5B + 3 PATCH1 + 4 PATCH2). Confirm the three Codex controlling states (ACCEPT_RS5A_PATCH4, NEED_RS5B_PATCH2, ACCEPT_RS5B_PATCH2 / PASS_WITH_CAVEATS).
2. Consolidated contract (file 02): eight required elements present — bootstrap posture (D-on-E), authority source (Constitution+Chairman, design-solved≠runtime-resolved), 13-element packet (item 13 unconditional), pure effect_identity, authorization_binding_digest includes effect, canonical_operation, BI oracle (P / Layer-1 BI-E6 / Layer-2 BI-E1), caveats. WHAT IS / IS NOT ACCEPTED lists complete.
3. Supersession map (file 03): S1 (RS5B-05 item-5 → PATCH1), S2 (PATCH1-02 register_dot → PATCH2 canonical_operation), S3 (PATCH1-04 BI overlap → PATCH2 layered), S4 (rollup "all revision 1" → caveat C1). Confirm nothing else reopened.
4. Caveat ledger (file 04): C1 revision typo (PATCH2-06 = rev 2); C2 classifier-only totality; C3 fixtures not executed; C4 no live runtime verification; C5 no P2/Chairman/runtime authorization. Each has source/risk/handling/blocks-closeout.
5. P2 entry gate (file 05): 12 conjunctive fail-closed requirements; deterministic gate order; future-only; P2_ENTRY_DESIGN_READY_FOR_INDEPENDENT_REVIEW is necessary-not-sufficient.
6. Carrier scope (file 06): C1–C7 each with born/test/change/rollback/join + pre/post-runtime + must-not-inherit; explicit reference-only join graph; no mega-registry.
7. Bad inputs (file 07): XBI-1..XBI-10 each fail closed; no PASS/seal/digest; single-code determinism with RUNTIME_MUTATION_REJECTED short-circuit.

3. Adversarial checks a reviewer should run

• Does any file claim runtime proof, live verification, or executed tests? (Should be none; caveats C2–C4 forbid it.)
• Is BINDING_CHECK_PASS anywhere treated as a registration/authority PASS? (XBI-4 must reject it.)
• Is Codex PATCH2 acceptance anywhere treated as P2 authorization? (Caveat C5, XBI-1/XBI-2 must reject it.)
• Is canonical_operation vocabulary anywhere asserted as runtime-present? (Should remain REQUIRED_NOT_PRESENT; XBI-3.)
• Does any carrier merge with another or lack a rollback? (XBI-6/XBI-7.)
• Does approval authority inherit registration/activation authority anywhere? (R8, XBI-5.)
• Is REGISTRATION_HOLD retained and REGISTRATION_CAN_PROCEED = NO in every file? (Yes.)

4. Allowed verdicts for the reviewer

RS5B_CLOSEOUT_P2_ENTRY_READY_FOR_GPT_REVIEW (this package's claim) · RS5B_CLOSEOUT_HOLD_UNIFIED_CONTRACT_AMBIGUOUS · RS5B_CLOSEOUT_HOLD_PATCH_CAVEATS_NOT_PROPAGATED · RS5B_CLOSEOUT_HOLD_P2_ENTRY_SCOPE_TOO_BROAD · RS5B_CLOSEOUT_HOLD_LEGO_BOUNDARY_INSUFFICIENT · RS5B_CLOSEOUT_REJECT_RUNTIME_MUTATION · RS5B_CLOSEOUT_REJECT_AUTHORITY_OVERCLAIM · RS5B_CLOSEOUT_REJECT_P2_OPENED_EARLY. In all cases REGISTRATION_HOLD carries forward unless a separately-authorized act clears it.

5. What acceptance of this package does and does not authorize

• Does: allow the P2 entry-gate design (file 05) to be treated as a reviewed baseline for a later independent review that decides whether P2 may open.
• Does not: open P2; authorize Chairman execution; create Owner/scope/APR/register_dot/approval/handler; create canonical-operation runtime rows; open RS-VALIDATOR; patch registrar/validator; register; activate; or clear REGISTRATION_HOLD.

6. DO NOT IMPLEMENT

No runtime mutation, DDL/DML, Owner/scope/principal/APR/register_dot/approval/handler, registrar/validator patch, RS-VALIDATOR, implementation, registration, activation, P2 authorization, vocabulary creation, or blocker resolution is performed or authorized by this package. Assembly Gate: PG/Directus/Nuxt = N/A; AgentData KB design-only. Data flow: direct AgentData reads + KB writes of this package only.
