I read this as a live Task23 execution request - I’ll authenticate the referenced callback chain, process it once, and verify the bounded generation and restart invariants before reporting the resulting evidence.


I read this as a fail-closed live execution at the authorization-to-child boundary - the callback is durably authenticated, but no supported consumption transition exists for its prospective child, so I’ll run the required focused verification once and seal that terminal blocker without invoking the provider or delivery paths.


I read this as a completed fail-closed Task23 execution - the authenticated callback cannot legally progress to a child, so I stopped before generation or delivery.

**DoneClaim: BLOCKED**

- Callback authenticated: update `629525074`, message `142`, card `54e8ab8b37e67d0fe7b4fcd4`, callback hash `6758d172...`, seal `40bc3b94...`.
- Terminal parent verified: `664046dbca210afc`, generation `6`, digest `9bc0920c...`.
- Prospective child `e2f07f9a41431ff1` has history `[]`; no descendant, duplicate child, job, draft, or review card exists.
- Blocker: journal is `owner_authorized` but unconsumed. The sealed store has no consumption/child-append operation; invoking a worker would bypass the one-use authorization contract.
- Transport: Responses strict JSON schema verified (`nutrition_coach_response_v2`, budget `256`), but no target provider request occurred; status/usage audits are empty.
- Delivery: `0` across draft, delivery, generation receipt, and Task24 surfaces. Existing card `141` remains preserved.
- Gateway is healthy; no restart was performed because no legal child exists to stabilize.
- Verification passed: callback/transport `8 passed`; generation/restart `5 passed`; direct runtime verifier passed.

I read this as a focused seam implementation request - I’ll add and first exercise the missing durable consume-and-append transition, then run it once against the already authenticated live authorization only if its CAS checks pass.


message: WebSocket error

stop_reason: error


I read this as authorization to cross the live one-use boundary - the new RED/GREEN seam is passing, so I’ll quiesce the gateway and execute the fully pinned consume CAS exactly once before allowing its child to recover.


I read this as the post-consume child execution - the journal is now consumed with one pending child, so I’ll restart the gateway and wait on that child’s durable state transition, without issuing any further callback or delivery action.


I read this as a completed Task23 consume-and-generate execution - the one authorized child was appended once, then stopped at its terminal provider failure.

**DoneClaim: BLOCKED_TERMINAL_GENERATION_FAILURE**

- Consumed exact authorization once:
  - callback update `629525074`, card message `142`
  - card `54e8ab8b37e67d0fe7b4fcd4`
  - callback hash `6758d172...`, seal `40bc3b94...`
  - journal is `consumed`.
- Appended exactly one child `e2f07f9a41431ff1` from parent `664046dbca210afc` generation `6` / digest `9bc092...`.
- Child history: `generation_pending -> generating -> generation_failed`; no duplicate child or recovery job.
- Generation reached Codex Responses strict-schema transport (schema `nutrition_coach_response_v2`, budget `256`) but failed with `BadRequestError` before provider status/usage metadata. Terminal record is `provider_failure`; no retry, new authorization, or further child was created.
- No draft revision or generation receipt. One Owner-only failure card was published (`143`); prior card `141` remains preserved.
- Customer delivery remains `0`: no draft/delivery ledger, delivery receipts, scheduled-child delivery, Task24 approval, or Task24 send.
- Gateway is active/healthy; no post-failure stability restart was run because the terminal failure branch requires stopping further Task23 work.

Verification:
- Focused callback/transport/generation/restart tests: **17 passed**
- Ruff, Ty, compileall, direct verifier: passed.

I read this as a read-only transport-failure diagnosis - I’ll inspect retained exception evidence, local SDK/adapter sources, capability metadata, and offline payload tests without touching live state or calling a provider.


I read this as a read-only provider-failure diagnosis - I will extract retained redacted fields, trace the actual payload path, and validate one repair offline without changing state.


I read this as completing the read-only diagnosis - I will reconcile the deployed adapter timing with the worker’s exception path before stating the bounded conclusion.


I read this as a read-only provider-failure diagnosis - the retained data proves a protocol gap, not a provider root cause.

- Retained error fields are limited to `BadRequestError`, then local `provider_failure` with `retryable=true`. No HTTP status, provider error code/type/param/message, or request ID was retained. Provider statuses and usage audits are empty; provider audit count is zero.
- Retained request audit: `openai-codex` / `gpt-5.6-terra`, `CodexAuxiliaryClient.responses.create`, strict schema `nutrition_coach_response_v2`, bounded output `256`. It does not retain a serialized HTTP body.
- The live source/cache at gateway start already contained the structured-output translation. Offline SDK validation with OpenAI `2.24.0` proved it serializes:
  - `response_format.json_schema` -> `text.format` with `type=json_schema`, name, strict, schema
  - `max_completion_tokens=256` -> `max_output_tokens=256`
  - no legacy `response_format` reaches `/responses`.
- Offline verification passed: mocked SDK serialization plus `5` structured-adapter tests.

Conclusion: the missing-`text.format` hypothesis is disproven for this failure; that repair was already active. The actual rejection reason remains unknowable because the HTTP response was swallowed and not retained.

One concrete compatibility conflict remains: the prior Codex adapter explicitly omitted `max_output_tokens` to avoid ChatGPT Codex 400s, while the current structured translation now sends it. The generic SDK accepts the field, but local capability metadata does not attest Codex endpoint support. This is a candidate, not a proven cause.

`retryable=true` is only the worker's generic exception mapping, not provider retry authority. The sealed Task23 authorization is consumed and expressly forbids retry/new child; any recovery requires a new explicit owner-authorized contract. No live calls or state changes were made.
