## Summary

Completed typed Responses protocol-operation admission and its public error contract after three official review verdicts; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G04_02.log` | `code_review_cloud_G04_02.log` | FAIL | The unsupported-profile handler test bypassed production operation admission, and the recorded default Go cache was not reproducible. |
| `plan_cloud_G07_02.log` | `code_review_cloud_G07_02.log` | FAIL | The typed service error, Responses mapping, regression updates, and current-loop verification evidence had not been implemented. |
| `plan_cloud_G06_03.log` | `code_review_cloud_G06_03.log` | PASS | Typed initial/live operation rejection, generic-sentinel compatibility, exact HTTP 400 mapping, faithful handler fake ordering, and deterministic verification all passed. |

## Implementation and Cleanup

- Added `ProviderPoolOperationUnsupportedError` and ordered concrete-profile operation admission before request-local candidate filtering during initial and live provider-pool resolution.
- Preserved terminal queue compatibility through `errors.Is(..., ErrProviderPoolCandidateRejected)` while preventing unsupported operations from reserving a slot or sending a Node request.
- Mapped only the typed Responses rejection to HTTP 400 `invalid_request_error` with the sanitized operation-specific message.
- Aligned the OpenAI handler test double with production admission ordering and added focused initial, mixed-pool, legacy, live re-resolution, public envelope, provider-auth, body, and stream regressions.
