| `409` | Conflict — either the creation ceiling was reached for this organization (`agent_limit_reached`), or a request with the same Idempotency-Key is still in flight (`idempotency_in_progress`); retry the latter after the first attempt settles. |
| `422` | The Idempotency-Key was already used with a DIFFERENT request body (`idempotency_key_reused`). Reuse a key only to retry the identical request.                                                                                                |
