The pairing code check uses constant-time comparison, issue/reissue paths are race-checked, and confirmation is atomically conditioned on `expires_at`.\n\nAn active unconfirmed issuance is still redelivered without creating a second session; a confirmed session still fails closed against re-pairing. Expired confirmation responses are explicitly retryable and require a fresh pairing issuance. Synthetic regression fixtures never use `codex-v4` and are deleted in `finally`.\n\nThis changes bootstrap liveness only. It does not ACK the acceptance challenge, prove a real Codex runtime, grant merge authority, or change `production_go=false`.\n\n## Codex real-runtime acceptance verifier\n\nR4 adds a read-only, fail-closed verifier for the exact lane `CODEX_REAL_RUNTIME_ACCEPTANCE_V1`.\n\nProtected endpoint:\n\n- `GET /v1/acceptance/CODEX_REAL_RUNTIME_ACCEPTANCE_V1` — GPT/admin bearer only.\n\nThe verifier derives its contract from the stored acceptance challenge and never creates an ACK, message, pairing, authorization or production promotion. It reports only evidence-backed states:\n\n`CHALLENGE_NOT_PROVEN -> PENDING_CODEX_ACK -> PENDING_CODEX_RESPONSE -> PENDING_CHATGPT_ACK -> PASS_RUNTIME_ROUNDTRIP`\n\nAmbiguous, malformed or mechanically invalid evidence fails closed. `PENDING_CHATGPT_ACK` explicitly requires semantic review before the final GPT ACK. Even `PASS_RUNTIME_ROUNDTRIP` proves only continuity transport/runtime binding and always returns `production_go=false`.\n\nCurrent authenticated self-test observes `PENDING_CODEX_ACK`, which is consistent with the live ledger: the real Codex runtime has not yet ACKed the exact challenge.\n\n## R2 external authorization guard\n\nR3-GUARD adds an external, fail-closed authorization surface for the RUMBO Continuity R2 control package.\n\nProperties:\n\n- controller bearer is held only as an encrypted Val Town environment variable;\n- target repository is bound by an opaque immutable repository-identity SHA-256;\n- control package is pinned to one exact SHA-256;\n- authorization binds exactly to action, PR number, base SHA, head SHA, package SHA-256 and evidence SHA-256;\n- raw one-time authorization tokens are returned only at issuance;\n- only token SHA-256 values are persisted;\n- authorizations have a 60–900 second TTL;\n- exact request bindings cannot be re-issued because request SHA-256 is unique;\n- consumption is atomic and one-time;\n- replay, token mismatch, binding mismatch and stale/expired authorization fail closed;\n- ledger reads never expose token hashes;\n- guard lifecycle events are added to the existing audit hash chain;\n- `production_go` is always false on this surface.\n\n### Merge gate\n\n`MERGE_PR` issuance **and consumption** are disabled unless the runtime environment explicitly contains:\n\n`R2_ALLOW_MERGE_AUTHORIZATION=true`\n\nThat variable is intentionally absent. Therefore this runtime cannot presently authorize a PR merge.\n\nA green guard receipt is not product GO and cannot substitute for live GitHub-side observation of the exact PR state.\n\n## Guard endpoints\n\nAll guard endpoints require the dedicated R2 guard bearer except public health.\n\n- `POST /v1/guard/authorize`\n- `POST /v1/guard/consume`\n- `POST /v1/guard/revoke`\n- `GET /v1/guard/authorizations/:id`\n- `GET /v1/guard/ledger`\n\nThe temporary self-test route used during branch validation was removed before promotion.\n\n## Guard validation evidence\n\nThe branch implementation was exercised against the live Val Town runtime with an internal bearer self-test that did not expose the bearer or one-time token.\n\nFinal adversarial matrix:\n\n- unauthenticated ledger → 401;\n- merge issuance while disabled → 423;\n- invalid repository binding → 400;\n- TTL below policy → 400;\n- TEST_ONLY issuance → 201;\n- invalid consumer label → 400 with authorization still ISSUED;\n- exact TEST_ONLY consumption → 200;\n- consumed-token replay → 409;\n- duplicate exact authorization request → 409;\n- read of an expired fixture → effective status EXPIRED without mutating on read;\n- revoke of expired authorization → 410 and durable EXPIRED state;\n- pre-existing MERGE_PR fixture consumption while merge gate disabled → 423;\n- revoked merge fixture → 200;\n- ledger read → 200;\n- token-hash leakage check → false.\n\nValidated receipt SHA-256:\n\n`90d2e2fd1691b523e0a0ab182ad2f41dd9a6d8dd6ec2f06d8af19c24a58e82ab`\n\nThe live health endpoint remained 200 after removal of the temporary self-test route.\n\n## Continuity endpoints\n\n- `GET /health`\n- `GET /v1/state/:lane`\n- `GET /v1/inbox?lane=...`\n- `POST /v1/messages`\n- `POST /v1/acks`\n- `GET /v1/acceptance/CODEX_REAL_RUNTIME_ACCEPTANCE_V1` (GPT/admin; read-only)\n- `GET /v1/audit` (admin only)\n\n## Boundary\n\nThe relay is a transport, evidence surface and external fail-closed authorization ledger.
