## 错误码

| HTTP | 类型                      | 触发条件                                 |
| ---- | ----------------------- | ------------------------------------ |
| 401  | `authentication_error`  | PAT 无效或过期                            |
| 404  | `not_found_error`       | Session 或 thread 不存在                 |
| 409  | `invalid_request_error` | 协调器主线程不可归档、线程不在 `idle` 状态，或其它版本/状态冲突 |

**HTTP 404 Not Found**

```json theme={null}
{
  "type": "error",
  "request_id": "cb80235f-76a2-4ff3-9e28-5aa2da12dc14",
  "error": {
    "type": "not_found_error",
    "message": "Session thread 'sthr_fakefakefake_xxxxxxxxxxxxxxxx' was not found."
  },
  "request_id": "b5822072-f264-48da-9d61-6d48ffb07551"
}
```

**HTTP 409 Conflict**

```json theme={null}
{
  "type": "error",
  "request_id": "cb80235f-76a2-4ff3-9e28-5aa2da12dc14",
  "error": {
    "type": "invalid_request_error",
    "message": "Version or state conflict."
  }
}
```

无论冲突来自协调器角色、线程非 `idle` 状态还是其它并发冲突，409 响应都使用统一的 `"Version or state conflict."` 文案。需要进一步定位时，请通过 `GET /api/v1/cloud/sessions/{session_id}/threads/{thread_id}` 查看线程状态。
