+# FANUC 真机协议 Socket 通信层实现计划
+
+## 上下文
+
+当前 `flyshot-replacement` 项目已完成：
+- 三条 FANUC 通信链路的二进制协议编解码（`FanucCommandProtocol`、`FanucStateProtocol`、`FanucJ519Protocol`）
+- 抓包样本验证的协议测试（5 个 FanucProtocolTests 全部通过）
+- HTTP 兼容层控制器和状态监控页
+- 轨迹规划与飞拍触发编排层
+
+**缺失的关键环节**：`FanucControllerRuntime` 仍是纯内存状态桩，没有实际 Socket 通信。`Connect()` 只记录 IP，`ExecuteTrajectory()` 只修改内存变量，`GetJointPositions()` 返回的是上一次写入值而非真实控制器反馈。
+
+## 目标
+
+将 `FanucControllerRuntime` 从内存桩改造为具备真实 FANUC R30iB 通信能力的运行时，使 HTTP 层的每个指令真正下发到控制柜。
+
+## 架构设计
+
+### 分层结构
+
+```
+LegacyHttpApiController / StatusController  (HTTP 适配层，保持不动)
+    ↓ 调用同步接口
+IControllerRuntime / ControllerClientCompatService  (兼容层，保持不动)
+    ↓ 调用同步接口
+FanucControllerRuntime  (改造：从内存桩 → 委托给三个 Socket 客户端)
+    ↓ 内部持有并调度
+FanucCommandClient   (TCP 10012，Req/Res 同步命令通道)
+FanucStateClient     (TCP 10010，持续接收状态帧后台循环)
+FanucJ519Client      (UDP 60015，8ms 周期发送 + 接收响应)
+    ↓ 使用现有编解码
+FanucCommandProtocol / FanucStateProtocol / FanucJ519Protocol  (已有，不改动)
+```
+
+### 关键设计决策
+
+1. **接口保持同步**：`IControllerRuntime` 现有 18 个方法全为同步签名。内部 Socket I/O 采用 `Task` + `.GetAwaiter().GetResult()` 短时间阻塞，或后台线程 + 锁同步状态快照。避免一次性推翻整个兼容层。
+
+2. **三个独立客户端**：每条物理通道一个类，各自管理连接生命周期，便于单独测试和故障定位。
+
+3. **状态通道后台循环**：`FanucStateClient` 内部启动 `Task` 持续 `ReadAsync(90)`，解析状态帧后写入线程安全的 `ControllerStateSnapshot` 缓存。
+
+4. **J519 周期发送器**：`FanucJ519Client` 内部用 `PeriodicTimer` 或 `Task.Delay` 实现约 8ms 周期的发送循环。命令通过线程安全的队列/缓冲区注入。
+
+5. **RVBUSTSM 程序生命周期隐式管理**：`EnableRobot()` 时自动走 `StopProg→Reset→GetProgStatus→StartProg("RVBUSTSM")` 序列（与抓包一致）。`DisableRobot()` 时发送 `StopProg`。
+
+6. **连接顺序**：`Connect()` 按顺序建立三条通道 — 先 TCP 10010（状态），再 TCP 10012（命令），最后 UDP 60015（运动）。
+
+## 实现步骤
+
+### Phase 1: TCP 10012 命令客户端
+
+**新建文件**：`src/Flyshot.Runtime.Fanuc/Protocol/FanucCommandClient.cs`
+
+职责：
+- `Connect(string ip, int port = 10012)` — 建立 TcpClient 连接
+- `SendCommandAsync(uint messageId, ReadOnlyMemory<byte> body)` — 发送并等待响应
+- `SendProgramCommandAsync(uint messageId, string programName)` — 封装程序名命令
+- `Disconnect()` — 关闭连接
+- 线程安全（单个命令通道同一时间只处理一个请求）
+
+需要封装的具体命令方法：
+- `StopProgramAsync(string name)` → `PackProgramCommand(0x2103, name)`
+- `ResetRobotAsync()` → `PackEmptyCommand(0x2100)`
+- `GetProgramStatusAsync(string name)` → `PackProgramCommand(0x2003, name)`
+- `StartProgramAsync(string name)` → `PackProgramCommand(0x2102, name)`
+- `GetTcpAsync()` / `SetTcpAsync()` — 待解析请求/响应体格式
+- `GetSpeedRatioAsync()` / `SetSpeedRatioAsync()` — 同上
+- `GetIoAsync()` / `SetIoAsync()` — 同上
+
+**测试**：`tests/Flyshot.Core.Tests/FanucCommandClientTests.cs`
+- 用 `TcpListener` 本地模拟控制器，验证帧收发与解析
+
+### Phase 2: TCP 10010 状态客户端
+
+**新建文件**：`src/Flyshot.Runtime.Fanuc/Protocol/FanucStateClient.cs`
+
+职责：
+- `Connect(string ip, int port = 10010)` — 建立 TcpClient 连接
+- 内部启动后台 `Task` 循环 `ReadAsync(FanucStateProtocol.StateFrameLength)`
+- 每收到一帧调用 `FanucStateProtocol.ParseFrame()`
+- 将解析结果写入线程安全的最新状态缓存
+- `GetLatestSnapshot()` — 返回最近一次解析的状态帧
+- `Disconnect()` — 取消后台循环并关闭连接
+
+**测试**：`tests/Flyshot.Core.Tests/FanucStateClientTests.cs`
+- 用 `TcpListener` 本地发送抓包样本 hex，验证后台循环能正确解析
+
+### Phase 3: UDP 60015 J519 运动客户端
+
+**新建文件**：`src/Flyshot.Runtime.Fanuc/Protocol/FanucJ519Client.cs`
+
+职责：
+- `Connect(string ip, int port = 60015)` — 创建 UdpClient
+- 发送 init packet (`PackInitPacket()`)
+- 内部启动发送循环（约 8ms 周期）
+- `UpdateCommand(FanucJ519Command command)` — 原子更新下一周期要发送的命令
+- `StartMotion()` — 启动发送循环
+- `StopMotion()` — 发送 end packet，停止循环
+- 接收线程：持续 `ReceiveAsync()` 解析 132B 响应，更新反馈状态
+- `Disconnect()` — 清理
+
+**测试**：`tests/Flyshot.Core.Tests/FanucJ519ClientTests.cs`
+- 用本地 UDP socket 模拟控制器收发
+
+### Phase 4: 重写 FanucControllerRuntime
+
+**改造文件**：`src/Flyshot.Runtime.Fanuc/FanucControllerRuntime.cs`
+
+将当前内存桩替换为真实运行时：
+
+- 持有三个客户端实例：`FanucCommandClient`、`FanucStateClient`、`FanucJ519Client`
+- `Connect(robotIp)` — 顺序连接 10010 → 10012 → 60015
+- `EnableRobot(bufferSize)` — 走完整 StartProg 序列（Stop→Reset→Status→Start RVBUSTSM），然后启动 J519
+- `DisableRobot()` — 停止 J519，发送 StopProg
+- `Disconnect()` — 断开三条通道
+- `ExecuteTrajectory(result, finalJointPositions)` — 将规划后的稠密路点通过 J519 逐帧发送
+- `StopMove()` — 立即停止 J519 发送循环
+- `GetSnapshot()` — 优先从 `FanucStateClient` 读取最新状态；若状态通道未连接，回退到内存值
+- `GetJointPositions()` / `GetPose()` / `GetTcp()` / `GetSpeedRatio()` / `GetIo()` — 优先从真实通道读取
+- `SetTcp()` / `SetSpeedRatio()` / `SetIo()` — 通过命令通道发送
+
+### Phase 5: 端到端集成测试
+
+**改造/新建测试**：
+- `tests/Flyshot.Server.IntegrationTests/LegacyHttpApiCompatibilityTests.cs` — 补充真实连接流程（可用本地模拟器）
+- `tests/Flyshot.Core.Tests/FanucControllerRuntimeSocketTests.cs` — 用本地 TCP/UDP 模拟器验证完整链路
+
+**验证命令**：
+```bash
+cd flyshot-replacement
+dotnet build FlyshotReplacement.sln -v minimal
+dotnet test tests/Flyshot.Core.Tests/Flyshot.Core.Tests.csproj -v minimal
+dotnet test tests/Flyshot.Server.IntegrationTests/Flyshot.Server.IntegrationTests.csproj -v minimal
+```
+
+## 风险与回退策略
+
+1. **真机连接风险**：第一版 Socket 实现可能有超时/重连问题。`FanucControllerRuntime` 保留 `_simulationMode` 路径，仿真模式下仍走内存桩。
+2. **性能风险**：同步接口内部阻塞 Socket 可能影响 HTTP 并发。若实测有问题，后续将 `IControllerRuntime` 改为 async。
+3. **协议字段不完整风险**：TCP 10012 的 `GetTcp`/`SetTcp`/`GetIo`/`SetIo` 请求/响应体格式尚未完全逆向。先实现已知字段，留 TODO 标记待验证。
