+## SystemService ActionQueue
+
+`SystemService/ExecuteActionQueue` 接收一个完整的有限动作序列，在边缘端排队并
+逐步串行执行，所有步骤结束后返回最终结果。平台只需要提交一次请求，因此连续机械臂
+动作不会再受到每个单独 gRPC 往返和 Wi-Fi 抖动的影响。
+
+当前 v1 仅允许以下 `ActionStep.command`：
+
+- 机械臂同步 `MoveJ`、`MoveL`；
+- AGV 同步 `navigateToPose`、`navigateToStation`、`followPath`；
+- 边缘端本地 `delay`。
+
+机械臂和 AGV 请求复用各自已有的类型化 Request，目标设备仍由每一步的
+`header.device_id` 指定。所有运动步骤必须设置 `asynchronous=false`；`MoveL` v1 仅接受
+Base frame；AGV 后端还必须明确支持同步导航终态确认。`speedJ`、`speedL`、`servoJ`、
+AGV `translate`、速度控制、查询和流式 RPC 都不属于 ActionQueue v1。
+
+ActionQueue 遵循以下执行语义：
+
+- 平台先调用 `GetSystemInfo` 读取 `action_service_instance_id`，并在每次提交和重试中填入
+  `expected_service_instance_id`。ActionQueue 账本随服务实例重建；若断线期间边缘服务重启，
+  旧实例 ID 会被拒绝，平台必须先对账，不能用新 ID 自动重放不确定的动作；
+- `action_id` 是必填的全局唯一幂等键；同一服务实例内，相同内容的已受理请求不会重复下发
+  设备命令，相同 ID 但内容不同的请求必须拒绝。服务端缓存最近 4096 个完整结果，更早的
+  已执行 ID 由精确 retired-ID 账本 fail-closed 拒绝、不会重跑；单实例最多记录
+  262144 个已受理 ID，达到容量后仅拒绝新 ID，已有 ID 仍可查询；
+- 入队前校验全部步骤、设备、参数和同步能力，校验失败时不会执行任何步骤；
+- v1 每个请求最多 256 步、序列化大小最多 512 KiB、排队或执行中的 Action 最多 64 个、
+  同时提交或等待结果的 RPC 最多 256 个；Action 与单步超时上限均为 24 小时，
+  `total_timeout_ms=0` 使用 30 分钟默认值，AGV 路径最多 4096 段；
+- `total_timeout_ms` 包含排队与执行时间，单步 `timeout_ms=0` 时继承 Action 剩余时间
+  或服务端默认值；所有超时值均由服务端施加上限；
+- 任一步失败、取消或超时后立即停止序列，不再执行后续步骤；`completed_steps` 表示此前
+  成功完成的步骤数，`failed_step_index` 仅在存在对应失败步骤时出现；
+- Action 一旦受理，不因平台连接中断而自动取消；断线只结束该 RPC waiter，边缘动作继续。
+  平台可用相同 `action_id` 重试并取得仍在缓存中的同一次执行结果；
+- `StopAll`、机械臂 `stopMotion`、AGV `cancelNavigation` 和软件急停不进入 FIFO，必须
+  作为高优先级安全/抢占路径执行。它们仍不具备功能安全等级。
+- 机械臂步骤超时会立即走 typed `stopMotion` 并等待停车确认；若无法确认停车，设备控制权
+  保持隔离，不会继续后续步骤或接受新的普通控制命令；需先按设备安全流程确认状态，再
+  重启边缘服务恢复控制。
+- AGV 的取消 ACK、零速度 ACK 均不等于停稳；ActionQueue 和安全停止 RPC 只有在导航任务
+  终态且底盘连续零速度采样确认后才释放控制权，否则同样保留隔离。
+
+已知的执行完成、业务失败、取消、超时和预校验拒绝由 `ActionResultCode` 与
+`CommandHeader.Feedback` 表达。`ActionDeduplicationStatus` 结构化区分新受理、合并等待、
+缓存结果、已淘汰结果、账本耗尽、ID 冲突和服务实例不匹配；平台不得通过解析错误字符串
+判断动作是否执行过。
+`ACTION_RESULT_CODE_UNSPECIFIED` 不得作为服务端最终结果。
+
