 - 当前已补 Codex App Server 受控线程回滚：`POST /api/v1/projects/[projectId]/thread-rollback` 会创建 `intentCategory=thread_rollback` 任务，`local-agent` 调用 `thread/rollback` 回滚目标线程最近 N 轮；该链路不启动新 turn，不把 thread/turn/items 原文写回 APP，只提示“线程历史已回滚”，且不会自动还原本地文件变更。

 - 当前 boss-agent 已支持 Mac OTA：`local-agent/boss-agent-ota-runner.mjs` 默认开启，每 5 分钟检查服务端最新包；状态页可手动检查或下载并安装，安装时保留原绑定配置，只更新版本号和本机 runtime 路径。最新验证版本为 `20260516221619`，已在 MacBook Air `macbook-air` 上确认 OTA 下载校验、暂存、覆盖安装后不会误切到默认 `config.cloud.json`。正式分发脚本已预留 Developer ID 公证路径：`BOSS_AGENT_NOTARIZE=1` 配合 notary profile 或 Apple ID 凭据。
 - 当前量产治理已补设备撤权和任务可靠性底座：`revoke_device` 会清空设备 token、标记离线并阻断 heartbeat / 任务认领 / Skill 同步 / 日志上报 / boss-agent OTA；`MasterAgentTask` claim 会记录 attempt 和 lease，运行中任务可按租约重试，超过上限转 `timed_out`，用户或管理员可通过 cancel 接口转 `canceled` 且迟到 complete 不覆盖终态。
 - 当前群聊 `dispatch_execution` 完成回写已补幂等，重复完成不会再向群聊重复追加结果
