+# 数据流转
+
+## 1. 概念约定
+
+- **物理设备**：真实硬件端口（当前主要是串口），由 `SerialQtDriver` 直接读写。
+- **设备实例**：`SerialDevice`，负责单设备生命周期、驱动回调、上下行数据接入。
+- **原始总线消息**：`RawBusMessage`，包含 `endpoint`、`protocolHint`、`payload`、`traceId`、`direction` 等基础字段。
+- **流水线上下文**：`PipelineContext`，继承 `RawBusMessage`，增加 `frameKind`、`frameSeq` 等管道字段。
+- **业务消息**：经过协议解析和映射后得到 `DOMMessage`（统一语义数据）。
+
+---
+
+## 2. 上行主链路（串口 -> 消息总线）
+
+### 2.1 设备初始化
+
+`SerialDeviceManager` 完成以下动作：
+
+1. 根据配置创建并配置 `SerialQtDriver`（波特率、校验、停止位、流控）。
+2. 创建 `SerialDevice` 并注入 `DeviceInfo`（含协议提示，如 `modbus_rtu`）。
+3. 通过 `bindIngress(...)` 绑定：
+   - `IIngressPort`（当前实现为 `DriverIngressAdapter`）
+   - `MemoryPool`（用于 payload 内存块分配）
+4. 调用 `start()` 打开端口并注册读回调/错误回调。
+
+### 2.2 读回调进入 ingress
+
+当串口收到字节流时，`SerialDevice::onRead(...)` 执行：
+
+1. 从 `MemoryPool` 分配内存块并拷贝原始字节。
+2. 构造 `RawBusMessage`：
+   - `direction = Upstream`
+   - `endpoint = 串口名`
+   - `protocolHint = DeviceInfo.protocol`
+   - `payload/payloadSize = 原始字节数据`
+   - `traceId = serial:<endpoint>:<timestamp>`
+3. 调用 `m_ingress->push(std::move(ctx))` 进入统一入口。
+4. 若内存池不足或 ingress 队列满，通过 `reportError(...)` 记录错误。
+
+### 2.3 ingress 适配为 PipelineContext
+
+`DriverIngressAdapter::push(...)` 负责轻量转换：
+
+1. 新建 `PipelineContext`。
+2. `pipelineCtx.raw() = std::move(ctx)` 将原始消息搬运进管道上下文。
+3. 调用 `PipelineEngine::enqueueIngress(...)` 入总线处理队列。
+
+---
+
+## 3. PipelineEngine 内部流转
+
+### 3.1 入口分流
+
+`enqueueIngress(...)` 分两种模式：
+
+- **并行模式（parallelPipeline=true）**
+  - 按 `endpoint` 创建/复用独立 `EndpointFramingState`（每端点一个分帧线程 + chunk 队列）。
+  - chunk 先进入端点队列，端点线程负责分帧并赋值 `frameSeq`。
+  - 完整帧进入 `m_framedQ`，由解析线程池处理。
+- **单线程模式（parallelPipeline=false）**
+  - 直接进入 `m_ingressQ`，由单 worker 串行处理。
+
+### 3.2 Stage 1：分帧（Framer）
+
+`dispatchFramer(...)` 的选择策略：
+
+1. 优先根据 `protocolHint` 从插件管理器选择协议分帧插件。
+2. 按 `endpoint + pluginId` 复用 framer session（保持协议状态机连续性）。
+3. 若没有可用插件，降级到 `PassthroughFramer`（透传/整包策略）。
+
+输出：`frameKind = CompleteFrame` 的帧批次。
+
+### 3.3 Stage 2/3/4：解析 -> 过滤 -> 校验
+
+`runStages234(...)` 核心流程：
+
+1. **Stage2 Parser**
+   - 选择 `IProtocolPlugin`，复用 parser session。
+   - `parse(rawCtx, envelope)` 产出协议封装 `ProtocolEnvelope`。
+   - 选择 mapper 插件并映射为 `std::vector<DOMMessage>`。
+2. **Stage3 Filter**
+   - 对 `DOMMessage` 执行过滤规则（`ProtocolParseFilter::process`）。
+3. **Stage4 Validator**
+   - 最低校验当前为 `messageId` 非空。
+4. **Transform/Enrich**
+   - 应用动态规则（scale/offset/unit）。
+   - 写入 trace，补充富化字段。
+
+说明：当前 `runStages234` 只返回布尔结果，`EnrichedMessage` 由内部生成，后续可接持久化/发布环节。
+
+### 3.4 出口与有序保证
+
+- 未开启有序出口：解析成功后直接进入 `m_egressQ`。
+- 开启 `orderedEgress`：
+  - 解析线程先写入 `m_mergeQ`。
+  - `mergerLoop` 按 `endpoint + frameSeq` 重排。
+  - 使用 `nextExpected` 保证同端点有序输出。
+  - 超过 `maxReorderDepth` 的乱序缓存上限会丢弃并计数。
+
+---
+
+## 4. 错误与背压点
+
+主要失败点及表现：
+
+1. **内存池分配失败**：`SerialDevice::onRead` 直接 `reportError(memory pool exhausted)`。
+2. **入口队列满**：`enqueueIngress` 返回 false，计入 drop。
+3. **分帧/解析插件缺失或失败**：对应帧在阶段中被丢弃。
+4. **过滤/校验失败**：消息跳过，不进入下游。
+5. **重排深度超限**：`mergeDrop` 增加并告警。
+
+---
+
+## 5. 当前链路时序（上行）
+
+```text
+SerialQtDriver(read callback)
+  -> SerialDevice::onRead
+    -> MemoryPool::allocate + RawBusMessage
+      -> IIngressPort::push (DriverIngressAdapter)
+        -> PipelineEngine::enqueueIngress
+          -> [Framer] dispatchFramer/feedChunk
+            -> [Stage2] parse + map -> DOMMessage
+              -> [Stage3] filter
+                -> [Stage4] validate
+                  -> transform/enrich
+                    -> egressQ (有序模式下先 merge 再 egress)
+```
+
+---
+
+## 6. 下行（现状）
+
+- `RawBusMessage.direction` 已支持 `Downstream` 语义。
+- `SerialDevice` 已提供 `writePayload(...)` 写入能力。
+- 当前代码中 egress 路由到物理设备的绑定仍预留（`SerialDeviceManager` 里相关逻辑已注释），后续可补齐：
+  - egress 消息 -> `EgressRouter` -> endpoint 设备 -> `writePayload`。
+
+---
+
+## 7. 维护建议
+
+1. `traceId` 建议在全链路透传到最终发布侧，便于定位帧级问题。
+2. 为 Stage2/Stage3/Stage4 增加细粒度指标（成功率、耗时、drop 原因）。
+3. 文档后续可新增“协议插件开发约定”章节（framer/parser/mapper 三类插件接口对照）。
