+# 高可靠任务调度协议设计 (High Reliability Task Scheduling Protocol)
+
+**日期**: 2025-11-29  
+**状态**: Implemented (Testing Pending)  
+**优先级**: High  
+**背景**: 当前 Workflow 采用 "Fire-and-Forget" 模式，导致当 Provider 处于降级、网络分区或宕机状态时，Orchestrator 无法感知，造成任务“假死”且无法自动恢复。
+
+## 1. 核心设计理念
+
+将 Orchestrator 从简单的“发令员”升级为“任务监理”，对任务进行全生命周期管理。引入 **握手 (Handshake)**、**心跳 (Heartbeat)** 和 **熔断 (Circuit Breaking)** 机制。
+
+## 2. 协议流程图
+
+### 2.1 正常调度流程 (Happy Path)
+
+```mermaid
+sequenceDiagram
+    participant O as Orchestrator
+    participant P as Provider (Worker)
+    
+    O->>P: Dispatch Task (Request)
+    activate O
+    P->>O: Acknowledgement (Accepted)
+    deactivate O
+    Note over O: Task Status: Running
+    
+    loop Execution
+        P->>P: Processing...
+        P->>O: Heartbeat (Progress Update)
+        Note over O: Reset Watchdog Timer
+    end
+    
+    P->>O: TaskCompleted (Result)
+    Note over O: Task Status: Completed
+```
+
+### 2.2 拒绝调度流程 (Provider Degraded)
+
+Provider 在降级模式下不再通过 Sleep 阻塞，而是保持连接并快速拒绝任务。
+
+```mermaid
+sequenceDiagram
+    participant O as Orchestrator
+    participant P as Provider (Degraded)
+    
+    O->>P: Dispatch Task (Request)
+    activate O
+    P->>O: Acknowledgement (Rejected: "API Key Missing")
+    deactivate O
+    
+    Note over O: Task Status: Failed/Skipped
+    O->>O: Trigger Failure Handling
+```
+
+### 2.3 调度超时 (Dispatch Timeout)
+
+Provider 宕机或网络断连。
+
+```mermaid
+sequenceDiagram
+    participant O as Orchestrator
+    participant P as Provider (Dead)
+    
+    O->>P: Dispatch Task (Request)
+    activate O
+    Note right of O: Wait 5s...
+    O->>O: Timeout Error
+    deactivate O
+    
+    Note over O: Task Status: Failed (Dispatch Error)
+```
+
+### 2.4 执行超时/心跳丢失 (Execution Watchdog)
+
+任务开始执行后，Worker 意外死亡。
+
+```mermaid
+sequenceDiagram
+    participant O as Orchestrator (Monitor Loop)
+    participant P as Provider
+    
+    P->>O: Heartbeat (T=0)
+    P->>P: Crash! 💥
+    
+    loop Every 1s
+        O->>O: Check Active Tasks
+    end
+    
+    Note over O: Now > LastHeartbeat + 30s
+    O->>O: Mark Task Failed (Zombie)
+```
+
+## 3. 实施任务清单 (Implementation Tasks)
+
+### Phase 1: 协议定义 (Common Contracts)
+- [x] **Define `TaskAcknowledgement` DTO**:
+  - `Accepted`
+  - `Rejected { reason: String }`
+- [x] **Define `TaskHeartbeat`**:
+  - 复用 `WorkflowEvent::TaskStateChanged`，当 `status=Running` 时视为心跳。
+
+### Phase 2: 调度器改造 (Orchestrator)
+- [x] **Refactor `dispatch_task`**:
+  - 从 `nats.publish` 改为 `nats.request`。
+  - 设置 strict timeout (e.g., 5s)。
+  - 处理 `Rejected` 响应，立即置为 Failed。
+- [x] **Implement `TaskMonitor`**:
+  - 新增后台 Tokio Task。
+  - 维护 `RunningTasks` 列表，包含 `last_heartbeat_at` 和 `started_at`。
+  - 逻辑:
+    - `if (now - started_at > max_timeout) -> Fail (Timeout)`
+    - `if (now - last_heartbeat_at > heartbeat_timeout) -> Fail (Zombie)`
+
+### Phase 3: 提供者改造 (Provider Services)
+以 `tushare-provider` 为首个改造对象，其他 Provider 后续跟进。
+
+- [x] **Remove Blocking Sleep**:
+  - 即使在 `Degraded` 状态，也要连接 NATS。
+- [x] **Implement Ack Logic**:
+  - 收到 Command 后，先检查自身状态。
+  - 如果 `Degraded`，回复 `Rejected`。
+  - 如果正常，回复 `Accepted` 并开始异步执行。
+- [x] **Implement Heartbeat**:
+  - 在长耗时操作（如 Fetch）中，定期发送进度/心跳事件。
+  - 已在 `WorkflowNodeRunner` 层面统一实现。
+
+### Phase 4: 验证与测试 (Validation)
+- [ ] **Unit Tests (Contracts/Orchestrator)**:
+  - 验证 Ack 序列化/反序列化。
+  - 验证 TaskMonitor 的超时逻辑（Mock 时间/Task）。
+- [ ] **Component Test (Mock Provider)**:
+  - 创建一个 Mock Provider，模拟：
+    - 正常 ACK + 完成。
+    - 正常 ACK + 半路 Crash（测试心跳丢失）。
+    - 拒绝 ACK (Degraded)。
+    - 根本不 ACK (Timeout)。
+  - 验证 Orchestrator 在上述情况下的状态流转是否正确。
+
+## 4. 预期效果
+1. **快速失败**: 系统不再因为配置错误（如缺 Key）而 hang 住 5 分钟，而是毫秒级报错。
+2. **自我修复**: 遇到网络波动导致的丢包，Orchestrator 能感知并（未来）触发重试。
+3. **可观测性**: 能够清晰区分 "调度失败"、"拒绝执行" 和 "执行超时" 三种错误模式。

+# Tushare 报表呈现优化任务 (Report Presentation Refactor)
+
+## 1. 背景与问题
+目前的 Tushare 数据以 `metric_name` + `period_date` 的长表形式存储和展示。
+问题：
+- **可读性差**：无法直观对比同一时间点下的不同指标，也无法直观对比同一指标的历史趋势。
+- **缺乏语义**：原始字段如 `c_pay_acq_const_fiolta` 对普通用户极其晦涩。
+- **精度冗余**：`1420023169.52` 这样的数字难以快速阅读。
+
+## 2. 设计目标 (Design Goal)
+生成一份结构化、人类可读的 Markdown 报告，必须**包含所有原始数据**，无损且清晰。
+
+### 2.1 核心转换逻辑 (Pivot)
+- **全量保留**：所有原始数据中的 `metric_name` 都必须展示，不可遗漏。
+- **行 (Rows)**: 财务指标 (Metrics)，需映射为中文名称，并进行逻辑分组（如利润表、资产负债表）。未匹配到字典的指标显示原始 Key。
+- **列 (Columns)**: 报告期 (Period Date)，按时间倒序排列。
+- **值 (Values)**: 格式化后的数值 (e.g., 亿元、万元、百分比)。
+
+### 2.2 展示结构 (Sectioning)
+采用**“按年份分组”+“指标分组”**的嵌套结构，利用 Markdown 标题层级进行索引。
+- **Data Provider 仅负责数据格式化，不涉及 LLM 摘要生成。**
+- **纯数据展示**：不生成任何自然语言评论或摘要。
+
+**结构示例：**
+
+```markdown
+# 600521.SS 财务数据明细
+
+## 2025年度
+### 关键指标
+| 指标 | 2025-09-30 | ... |
+| :--- | :--- | :--- |
+| 总市值 | 14.20 亿 | ... |
+
+### 资产负债表
+...
+
+## 2024年度
+### 关键指标
+| 指标 | 2024-12-31 | 2024-09-30 | 2024-06-30 | 2024-03-31 |
+| :--- | :--- | :--- | :--- | :--- |
+| ... | ... | ... | ... | ... |
+
+### 资产负债表
+...
+```
+
+*分段策略：按**年份**（Year）进行一级切分。每年包含该年所有已披露的报告期。这种方式索引最清晰，且单表列数固定（通常最多4列），完美适配阅读。*
+
+## 3. 实施步骤 (Implementation Plan)
+
+### Step 1: 数据字典完善 (Data Dictionary)
+- 完善 `docs/5_data_dictionary/` 下的定义。
+- 建立 `metric_name` -> `Display Name (CN)` 的全量映射表。
+
+### Step 2: 数据转换逻辑 (Transformation)
+- **分组算法**: 
+    - 解析 `period_date` 提取年份。
+    - 按年份将数据归类到不同的 `YearBlock`。
+    - 年份倒序排列（2025 -> 2024 -> ...）。
+    - 年份内部按日期倒序排列（12-31 -> 09-30 ...）。
+- **行分类算法**: 将 Metrics 分为 `Snapshot`, `Income`, `Balance`, `CashFlow`, `Ratios`, `Misc`。
+- **格式化**: 
+    - 金额: 除以 10^8 保留 2 位小数 (e.g., "14.20 亿")。
+    - 比例: 乘 100 保留 2 位小数 (e.g., "15.30%").
+    - 人数/户数: 整数或“万”单位。
+
+### Step 3: Markdown 渲染 (Rendering)
+- 实现分层渲染：
+    1.  Level 2 Title: `## 2024年度`
+    2.  Level 3 Title: `### 资产负债表`
+    3.  Table: 渲染该年份内的该类指标。
+
+## 4. 详细设计与映射 (Detailed Design)
+
+### 4.1 字段映射表 (Field Mapping Dictionary)
+
+**A. 摘要与市场 (Snapshot & Market)**
+| Metric Key | 中文显示 | 单位策略 |
+| :--- | :--- | :--- |
+| `total_mv` | 总市值 | 亿 (保留2位) |

+# 任务：Realtime Logs 数据流优化 (缓冲与回放) [已完成]
+
+## 目标
+解决前端 `Realtime Logs` 面板在页面刷新、重新连接或初始加载延迟时丢失日志的问题。
+目标是确保 "First-hand" 服务端日志能够可靠地流向前端，不依赖 NATS 的临时性。
+
+## 实施方案
+
+### 1. 后端：增强 `SyncStateCommand` (Orchestrator)
+我们需要修改 `handle_sync_state` 逻辑，使其在发送状态快照的同时，**也能读取当前的临时日志文件**，并将历史日志作为事件发送给前端。
+
+*   **修改 `workflow.rs` -> `handle_sync_state`**:
+    *   调用 `log_manager.read_current_logs(req_id)` (需要新增此方法，非破坏性读取)。
+    *   读取到的日志内容可能是巨大的字符串。为了不阻塞 NATS 消息，可以分块发送，或者作为 `WorkflowStateSnapshot` 的一部分发送（如果大小允许）。
+    *   **方案选择**: 发送一个新的事件类型 `WorkflowLogHistory` 或者复用 `TaskLog`（批量发送）。
+    *   鉴于前端 `handleEvent` 处理 `TaskLog` 是追加式的，我们可以循环发送 `TaskLog` 事件。
+    *   **更优方案**: 在 `WorkflowStateSnapshot` 结构体中增加 `logs: Vec<String>` 字段。这样前端在恢复快照时一次性填入。
+
+### 2. 定义数据结构变更
+*   **`common-contracts/src/messages.rs`**:
+    *   修改 `WorkflowStateSnapshot`，增加 `logs: Vec<String>`。
+
+### 3. 完善 `LogBufferManager`
+*   **`logging.rs`**:
+    *   新增 `read_current_logs(&self, request_id: &str) -> Result<Vec<String>>`。
+    *   读取文件，按行分割，返回 `Vec<String>`。
+
+### 4. 前端适配
+*   **`useWorkflowStore.ts`**:
+    *   在 `handleEvent` -> `WorkflowStateSnapshot` 分支中，处理 `event.payload.logs`。
+    *   将这些日志合并到 `state.logs` (Global Logs) 或者解析后分发到 `state.tasks` (如果日志格式包含 Task ID)。
+    *   目前日志格式为 `[ISO Time] [Level] Message`，不一定包含 Task ID，所以主要作为 Global Logs 展示。
+
+### 5. 流程梳理
+1.  **前端启动/刷新**: 
+    *   调用 `SSE /events/{id}`。
+    *   API Gateway 收到连接，订阅 NATS，并发送 `SyncStateCommand` 给 Orchestrator。
+2.  **Orchestrator**:
+    *   收到 `SyncStateCommand`。
+    *   生成 DAG 快照。
+    *   **读取 `temp_logs/{id}.log`**。
+    *   构建 `WorkflowStateSnapshot` (包含 logs)。
+    *   发布到 NATS。
+3.  **前端接收**:
+    *   收到 Snapshot。
+    *   恢复 DAG 状态。
+    *   恢复 Logs 面板内容。
+4.  **后续实时日志**:
+    *   Orchestrator 继续运行，Tracing Layer 写入文件。
+    *   **关键点**: 我们之前删除了 `publish_log`。现在需要恢复**实时推送**能力，但不是手动调用。
+    *   **方案**: `FileRequestLogLayer` 除了写文件，还应该有一个机制将日志推送到 NATS 吗？
+    *   **回答**: 是的。之前的重构把推送删了，导致前端**收不到实时更新**了。
+    *   **修正**: `FileRequestLogLayer` 应该同时负责：
+        1.  写文件 (持久化缓冲)。
+        2.  推送到 NATS (实时展示)。
+    *   **技术难点**: Layer 是同步的，NATS 是异步的。
+    *   **解决**: 使用 `tokio::sync::broadcast` 或 `mpsc` 通道。Layer 将日志发送到通道，有一个后台 Task 负责接收通道消息并推送到 NATS。
+
+## 修正后的后端任务列表
+
+1.  **恢复实时推送通道**:
+    *   在 `AppState` 中增加一个 `log_broadcast_tx` (sender)。
+    *   `FileRequestLogLayer` 持有这个 sender。
+    *   在 `main.rs` 启动一个后台任务，监听 receiver，将日志封装为 `WorkflowEvent::TaskLog` 并推送到 NATS。
+2.  **实现历史回放 (Snapshot)**:
+    *   修改 `WorkflowStateSnapshot` 增加 `logs` 字段。
+    *   `LogBufferManager` 增加读取方法。
+    *   `handle_sync_state` 填充 logs。
+
+## 前端任务列表
+1.  更新 `WorkflowStateSnapshot` 类型定义。
+2.  在 Store 中处理 Snapshot 携带的日志。
+
+这个方案兼顾了实时性和可靠性（断线重连）。

+# 任务：重构工作流日志 (基于文件缓冲的持久化方案) [已完成]
+
+## 背景 (Context)
+目前 `workflow-orchestrator-service` 通过 `publish_log` 手动向 NATS 发送日志，这种方式既不规范，也导致了“双重日志”问题（Rust 标准日志 vs 前端 NATS 日志），且无法持久化保存。
+
+我们需要一种方案，能自动捕获 Rust 标准日志（`tracing`），将其暂存，并在工作流结束时归档到全局上下文（VGCS）中。考虑到日志可能非常长，为了避免内存溢出（OOM）和保证数据安全，我们将采用**文件系统**作为临时缓冲区，而不是内存。
+
+## 目标 (Objectives)
+1.  **清理 (Cleanup)**: 删除 `workflow-orchestrator-service` 中所有手动的 `publish_log` 和 `WorkflowEvent::TaskLog` 发送逻辑。
+2.  **捕获 (Capture)**: 实现一个自定义的 `tracing` Layer，能够识别当前的 `request_id`，并将日志实时追加写入到磁盘上的临时文件中。
+3.  **持久化 (Persistence)**: 当工作流结束（无论成功或失败）时，读取对应的临时日志文件，将其存入 VGCS 仓库（`workflow.log`），然后清理临时文件。
+
+## 实施方案 (Implementation Plan)
+
+### 1. 日志管理器 (`LogBufferManager`)
+创建一个新的结构体 `LogBufferManager`，用于管理临时日志文件。
+
+*   **目录**: 在服务根目录下创建 `temp_logs/` 目录。
+*   **路径策略**: 每个请求对应一个文件，例如 `temp_logs/{request_id}.log`。
+*   **功能**:
+    *   `append(request_id, message)`: 以追加模式打开（或创建）文件，写入日志行。为了性能，可以考虑持有活跃文件的句柄缓存（`DashMap<String, File>`），或者简单地每次打开（OS层面对追加写的缓存通常已经很好）。考虑到并发量不大，**每次 Open 追加**是最稳妥且无状态的，不容易出 Bug。
+    *   `finalize(request_id)`: 读取完整文件内容，返回 `String` 或 `Vec<u8>`，然后**删除**该文件。
+
+### 2. 自定义 Tracing Layer (`FileRequestLogLayer`)
+在 `workflow-orchestrator-service` 中新建 `logging` 模块。
+
+*   实现 `tracing_subscriber::Layer`。
+*   **逻辑 (`on_event`)**:
+    1.  从 Span 的 Extensions 中尝试获取 `request_id` (或者从 event 的字段中获取)。
+    2.  如果找到了 `request_id`：
+        *   格式化日志信息 (e.g., `[2025-11-30T10:00:00Z INFO] Message...`).
+        *   调用 `LogBufferManager::append(request_id, line)`.
+
+### 3. 更新 `AppState` 与 `main.rs`
+*   在 `AppState` 中加入 `pub log_manager: Arc<LogBufferManager>`。
+*   在 `main.rs` 中初始化 `LogBufferManager` (确保 `temp_logs` 目录存在)。
+*   配置 `tracing-subscriber`，将 `FileRequestLogLayer` 注册进去。注意：Layer 需要能访问到 `LogBufferManager`（可以通过全局静态变量或者在 Layer 构造时传入 Arc）。
+
+### 4. 重构 `WorkflowEngine` (`workflow.rs`)
+*   **移除旧代码**: 删除所有 `publish_log` 方法及其调用。
+*   **上下文传递**: 确保所有处理逻辑都在带有 `request_id` 的 Span 下运行。
+    *   例如: `let _span = tracing::info_span!("workflow", request_id = %req_id).entered();`
+    *   或者使用 `#[tracing::instrument(fields(request_id = %cmd.request_id))]`。
+*   **归档逻辑**:
+    *   在 `try_finish_workflow` (或处理完成/失败的地方)：
+    *   调用 `self.state.log_manager.finalize(req_id)` 获取完整日志。
+    *   使用 `self.state.vgcs` 将日志内容写入 `workflow.log` (或 `_execution.log`)。
+    *   提交到 VGCS。
+
+## 预期结果
+*   **稳定性**: 即使日志有几百 MB，也不会占用服务内存，只会占用磁盘空间。
+*   **隔离性**: 不同 Request 的日志写入不同的文件，互不干扰，支持高并发。
+*   **可观测性**: 未来通过 History API 可以查看到完整的、包含系统级信息的执行日志。
+
+## 约束与风险
+*   **磁盘空间**: 需定期清理 `temp_logs` 中可能因服务崩溃而残留的僵尸文件（可以在服务启动时清理，或者由 Cron 处理）。目前先在服务启动时打印警告或简单清理。
+*   **性能**: 频繁的文件打开/关闭（Append模式）在 SSD 上通常不是问题，但如果是极高频日志（每秒数千条）可能会有开销。鉴于我们的场景是分析任务，频率可控。

+日期: 2025-11-30
+版本: 2.1
 
 ## 1. 简介
 Fundamental Analysis Platform 是一个基于 AI Agent 的深度基本面投研平台，旨在通过自动化工作流聚合多源金融数据，并利用 LLM（大语言模型）生成专业的财务分析报告。
 
-v2.0 版本采用了全新的 Vite + React SPA 架构，提供了更流畅的交互体验和实时的分析状态可视化。
+v2.1 版本引入了动态配置架构、增强的实时日志流和结构化的数据报表展示，提供了更稳定和可视化的分析体验。

 *   **开始分析**: 点击“生成分析报告”按钮即可启动分析流程。
 
 ### 2.2 分析报告页 (Report View)
-核心工作区，分为左侧状态栏和右侧详情区。
+核心工作区，采用**双栏布局**：左侧为实时状态监控，右侧为多标签页详情展示。
 
-#### 左侧：工作流状态
-*   **可视化 DAG**: 展示当前的分析任务依赖图。
+#### 左侧：工作流状态 (Workflow Status)
+*   **可视化 DAG (Visualizer)**: 
+    *   展示当前的分析任务依赖图。节点显示**人类可读的任务名称** (如 "新闻分析", "财务数据获取")。
     *   **节点颜色**: 灰色(等待)、蓝色(运行中)、绿色(完成)、红色(失败)。
-    *   **动态连线**: 当任务运行时，连接线会有流光动画指示数据流向。
-*   **实时日志**: 滚动展示所有后台任务的执行日志，支持实时查看数据抓取和分析进度。
+    *   **动态连线**: 任务运行时显示流光动画，指示数据流向。
+*   **实时日志 (Real-time Logs)**: 
+    *   位于左侧底部（或独立面板），实时滚动展示所有后台任务的执行日志。
+    *   **历史回放**: 即使刷新页面或断线重连，系统也会自动拉取完整的历史日志，确保信息不丢失。
 
-#### 右侧：详情面板
-*   **Analysis Report**: 展示由 AI 生成的最终分析报告。支持 Markdown 格式（标题、表格、加粗、引用），并带有打字机生成特效。
-*   **Fundamental Data**: (开发中) 展示抓取到的原始财务数据表格。
-*   **Stock Chart**: (开发中) 展示股价走势图。
+#### 右侧：详情面板 (Detail Tabs)
+右侧区域根据分析流程动态生成多个标签页：
+
+*   **Overview (总览)**: 
+    *   展示整体分析进度、任务完成统计和总耗时。
+    *   如果任务失败，会在此处显示具体的错误信息摘要。
+*   **任务详情页 (Task Tabs)**: 
+    *   每个工作流节点（如 "Financial Data", "News Analysis"）都有独立的标签页。
+    *   **智能渲染**: 
+        *   **分析报告**: AI 生成的文本以 Markdown 格式渲染，支持富文本排版。
+        *   **财务数据**: 原始财务数据（特别是 Tushare A股数据）现在自动转换为**结构化 Markdown 表格**，按年份和报表类型分组，数值经过格式化（如 "14.20 亿"），便于阅读。
+    *   **Inspector (调试器)**: 点击右上角的 "Inspector" 按钮，可以打开侧边栏，查看该任务的输入/输出文件差异 (Diff) 和上下文信息，方便调试。
 
 ### 2.3 系统配置 (Config)
 集中管理平台的所有外部连接和参数。
 
 *   **AI Provider**:
     *   管理 LLM 供应商 (OpenAI, Anthropic, Local Ollama 等)。
-    *   配置 API Key 和 Base URL。
-    *   刷新并选择可用的模型 (GPT-4o, Claude-3.5 等)。
-*   **数据源配置**:
-    *   启用/禁用金融数据源 (Tushare, Finnhub, AlphaVantage)。
-    *   输入对应的 API Token。
-    *   支持连接测试。
+    *   支持配置 API Key、Base URL 和模型选择。
+*   **数据源配置 (Dynamic Data Sources)**:
+    *   **动态加载**: 支持的数据源列表（Tushare, Finnhub, AlphaVantage 等）及其配置项由后端动态下发，无需升级前端即可支持新数据源。
+    *   **功能**: 支持输入 Token/Key，并提供 **"Test Connection" (测试连接)** 按钮以验证配置是否有效。
 *   **分析模板**:
-    *   查看当前的分析流程模板（如 "Quick Scan"）。
-    *   查看每个模块使用的 Prompt 模板及模型配置。
+    *   查看当前的分析流程模板及各模块使用的 Prompt。
 *   **系统状态**:
     *   监控微服务集群 (API Gateway, Orchestrator 等) 的健康状态。
