## 一、模式与凭据

### 1.1 三种执行模式

| 模式      | 说明                                 | 所需环境变量                                                                                               | ASR 方式           |
| --------- | ------------------------------------ | ---------------------------------------------------------------------------------------------------------- | ------------------ |
| **apig**  | SkillHub 网关代理，Bearer Token 认证 | `ARK_SKILL_API_BASE` + `ARK_SKILL_API_KEY`（容器注入）+ `VOLC_SPACE_NAME` + `ASR_API_KEY` + `ASR_BASE_URL` | 豆包语音大模型     |
| **cloud** | 直连火山引擎 OpenAPI，HMAC 签算      | `VOLC_ACCESS_KEY_ID` + `VOLC_ACCESS_KEY_SECRET` + `VOLC_SPACE_NAME` + `ASR_API_KEY` + `ASR_BASE_URL`       | 豆包语音大模型     |
| **local** | 完全本地执行，无需云端服务           | 无（可选 `EXECUTION_MODE=local`）                                                                          | Qwen3-ASR 本地推理 |

**优先级**：`apig > cloud > local`。自动检测按此顺序依次检查环境变量，缺参时打印 `.env` 路径与缺失变量列表并自动降级。
