RS5B-CLOSEOUT-PATCH1 09 — Decision Packet — 2026-06-21

VERDICT: RS5B_CLOSEOUT_PATCH1_READY_FOR_GPT_REVIEW (not forced) Stop state: dependency-safe rollback contract + rollback-validity oracle + C7 conditionality + two-gate split recorded; awaiting independent review. Closes Codex HOLD RS5B_CLOSEOUT_P2_ENTRY_HOLD_DEPENDENCY_SAFE_ROLLBACK_AND_GATE_SPLIT_REQUIRED. Gate: REGISTRATION_HOLD · REGISTRATION_CAN_PROCEED = NO Mutations: 0 (KB-only, design-only; no live runtime read) PASS level: narrow Job-B patch consolidation + design-review-ready only — not authority / runtime / implementation / registration / activation PASS; not P2 authorization; not rollback-execution authorization. Evidence tier: AgentData KB direct read; controlling Codex HOLD + all closeout files read full; no chat summary/memory/local prose used as proof; NO_RUNTIME_VERIFICATION.

1. What was decided

PATCH1 is a narrow patch to closeout Job B. It does not rewrite Job A (Codex §3 accepted the consolidated contract; §12 "Do not reopen the accepted RS5B consolidated contract"). It fixes exactly the five things Codex §11 required:

  1. Dependency-safe rollback contract (file 02): destructive "drop/disable" replaced by versioned supersession / retire-with-history / compatibility / compensating transition, under invariants I1–I10, for every carrier C1–C7.
  2. Carrier dependency map (file 03): an explicit 8-edge graph with per-edge reference field, destruction impact, safe rollback rule, post-rollback invariant, and a bad input.
  3. Rollback-validity oracle + new XBI (file 04): RBP-0..RBP-9 / RBP-PASS classifier with a total precedence; XBI-11..XBI-25. Destructive-but-present plans are rejected before any PASS.
  4. C7 conditionality (file 05): deterministic approval_mode ∈ {APPROVAL_USED, APPROVAL_NOT_USED_BY_POLICY} rule.
  5. Two-gate split (file 06): Gate A P2_BASELINE_ENTRY_DESIGN_ACCEPTED (permits only preparing a plan) vs Gate B P2_OPEN_AUTHORIZED_FOR_NAMED_CARRIER_PLAN_ONLY (plan + rollback proof + preflight + scoped Chairman token + plan review).

2. Explicit closeout assertions (required by the controlling instruction §3.10)

  • Job A remains accepted. The consolidated RS5B_CONTRACT_AS_CORRECTED_BY_PATCH1_PATCH2 is not reopened; PATCH1 changes only Job-B rollback/C7/gate wording (file 07 §5).
  • Job B patch addresses the Codex HOLD residuals. All eight residuals R1–R8 (file 01 §4) are closed (files 02–06); the rollback-validity oracle closes the "presence-only" defect (R6); the gate split closes the circular R12 (R8).
  • Rollback is dependency-safe by invariant, not by label. Validity = I1–I10 conjunction proven over the explicit dependency graph and enforced by the RBP oracle — not the existence of a "rollback" sentence (file 02, file 03, file 04 §3).
  • C7 conditionality resolved. One approval_mode discriminator; no input is both required and not-required (file 05).
  • Gate A / Gate B split resolved. Two distinct outputs; no transition maps Gate-A acceptance to P2-open (file 06).
  • No P2 opened. P2 remains NOT_OPENED · NOT_AUTHORIZED.
  • No runtime. 0 mutations; RBP-0 short-circuits any observed write.
  • REGISTRATION_HOLD retained.
  • REGISTRATION_CAN_PROCEED = NO.

3. NOT accepted / NOT authorized

No runtime proof; no live runtime verification; no implementation; no Owner / scope / APR / register_dot / approval / handler created; no canonical-operation runtime vocabulary; no registrar/validator patch; no RS-VALIDATOR; no registration; no activation; no rollback execution (contract-validity ≠ execution authorization, I10); no P2-open; no Chairman authorization asserted to exist; no REGISTRATION_CAN_PROCEED.

4. Why this verdict (not another)

  • Not …_HOLD_CODEX_STYLE_RECONSTRUCTION_MISSING: the Codex-mode reconstruction is recorded (file 01 §0) and the residuals reconstructed from governed sections (file 01 §4).
  • Not …_HOLD_SOURCE_READ_FAILED: the Codex HOLD (13156 chars) and all closeout files were read full, truncated=false.
  • Not …_HOLD_ROLLBACK_STILL_DESTRUCTIVE: every C1–C7 destructive line is replaced by a preserve-history pattern (file 02 / file 07 M1–M6); the RBP oracle rejects any residual destructive plan (file 04 §3).
  • Not …_HOLD_DEPENDENCY_MAP_INCOMPLETE: all eight edges carry producer/consumer/reference field/break/safe-rule/invariant/bad-input (file 03 §4).
  • Not …_HOLD_ROLLBACK_VALIDITY_ORACLE_INCOMPLETE: a destructive plan cannot PASS because RBP-2..RBP-9 outrank RBP-1 and RBP-PASS (file 04 §3 proof).
  • Not …_HOLD_C7_CONDITIONALITY_AMBIGUOUS: the approval_mode rule is single-valued per act (file 05 §2).
  • Not …_HOLD_GATE_SPLIT_AMBIGUOUS: Gate A and Gate B have distinct inputs and outputs; no "Gate A → P2 open" transition exists (file 06 §4).
  • Not …_HOLD_XBI_INSUFFICIENT: XBI-11..XBI-25 cover destructive/orphan/erasure/weakening/successor/audit/locality/C7/gate, each single-coded (file 04 §4).
  • Not …_REJECT_SCOPE_DRIFT: PATCH1 touches only Job-B rollback/C7/gate; Job A untouched.
  • Not …_REJECT_RUNTIME_MUTATION: 0 mutations.
  • Not …_REJECT_AUTHORITY_OVERCLAIM: no authority/P2/runtime/rollback-execution claimed; ROLLBACK_CONTRACT_VALID_FOR_REVIEW is necessary-not-sufficient.
  • Not …_REJECT_P2_OPENED_EARLY: P2 not opened; Gate B requires a separate scoped Chairman token.

The verdict is not forced: had any C1–C7 rollback remained destructive, any edge lacked a bad input, C7 stayed ambiguous, the gates not separated, or a runtime write appeared, the corresponding HOLD/REJECT state above would have been emitted.

5. Must-not-do compliance (all 27 held)

No P2 opened; no carrier/Owner/scope/canonical_operation row/APR/approval/register_dot/handler created; no registrar/validator patch; no RS-VALIDATOR; no DDL/DML; no PG/Directus/runtime mutation; no implementation/registration/activation; REGISTRATION_HOLD not cleared; REGISTRATION_CAN_PROCEED not asserted; no claim rollback can execute; no claim P2 can open; no claim Chairman authorization exists; no deletion/suggestion-of-deletion of referenced identities/evidence (the entire patch forbids it); approval authority not inherited into registration/activation; design fixtures not treated as executed tests; classifier totality not treated as runtime totality; no mega-registry/mega-graph/mega-birth pipeline; every carrier born/test/change/rollback/join kept separate; engineering PASS distinguished from authority PASS; rollback-contract validity distinguished from rollback-execution authorization.

6. Carried blockers (UNCHANGED)

G2–G7 + STATUS_DOMAIN_NOT_DB_ENFORCED + U3_PARTIAL_UNIQUE_SURFACE_ABSENT + OWNER_MINT_PATH_FAIL_CLOSED + QUORUM_EFFECT_BINDING_INSUFFICIENT + QUORUM_APPROVER_IDENTITY_UNVERIFIED + BOOTSTRAP_AUTHORITY_UNRESOLVED + CANONICAL_PRINCIPAL_SURFACE_REQUIRED_NOT_PRESENT. No new blocker, no new reject code — the RBP / C7 / gate codes are entry-gate classifier labels, not runtime blockers, and resolve nothing.

8. Single next step

GPT/independent review of this PATCH1 only (dependency-safe rollback + rollback-validity oracle + C7 conditionality + two-gate split). On accept → Codex review. The corrected Job-B wording then carries into the closeout; the accepted closeout becomes the Gate A baseline. Only after a later independent acceptance of a carrier-specific build plan at Gate B, plus an explicit Chairman authorization scoped to that exact plan, may a named P2 design/build lane open. A still-later separate gate decides P3 registration. No P2 / runtime / registration / rollback-execution is authorized here. Residual ⇒ a future RS5B-CLOSEOUT-PATCH2.

Default HOLD. Deletion is not rollback. Rollback validity ≠ rollback presence. Rollback-contract validity ≠ rollback-execution authorization. Baseline acceptance ≠ P2-open authorization. Independent review ≠ Chairman authorization. Engineering PASS ≠ authority PASS. Contract PASS ≠ runtime PASS.
