+- 项目创建返回的 `signal_sources` 仅作为 AI Steward 创建结果区的内联展示，现阶段不新增独立页面路由；底层持久化统一复用现有 `SignalSourceRegistry`
 - 飞书长连接 websocket 在本地/CI 环境默认使用 `certifi` CA bundle 作为信任链；如需自定义 CA，可通过 `FEISHU_LONG_CONNECTION_SSL_CERT_FILE` 或 `SSL_CERT_FILE` 覆盖
 - 飞书长连接状态分为两层：`last_received_at/last_received_message_id` 表示 SDK 回调已收到事件，`last_event_at` 表示 worker 完成处理；排查“没吃进去”时必须优先看 `last_received_*`
 - 飞书长连接会话应复用 `Integration.config` 中已有的 `encrypt_key/verification_token`；配置保存时若未显式修改这两个字段，必须保留现有值，避免 SDK 因缺失事件密钥而拒收消息
