+# 重构任务：动态数据提供商配置架构 (Dynamic Data Provider Configuration)
+
+## 1. 背景与目标 (Background & Objective)
+
+目前系统的前端页面 (`DataSourceTab`) 硬编码了支持的数据源列表（Tushare, Finnhub 等）及其配置表单。这导致每增加一个新的数据源，都需要修改前端代码，违反了“单一来源”和“开闭原则”。
+
+本次重构的目标是实现 **“前端无知 (Frontend Agnostic)”** 的架构：
+1.  **后端驱动**：各 Provider 服务在启动注册时，声明自己的元数据（名称、描述）和配置规范（需要哪些字段）。
+2.  **动态渲染**：前端通过 Gateway 获取所有已注册服务的元数据，动态生成配置表单。
+3.  **通用交互**：测试连接、保存配置等操作通过统一的接口进行，不再针对特定 Provider 编写逻辑。
+
+## 2. 核心数据结构设计 (Core Data Structures)
+
+我们在 `common-contracts` 中扩展了服务注册的定义。
+
+### 2.1 配置字段定义 (Config Field Definition)
+
+不使用复杂的通用 JSON Schema，而是定义一套符合我们 UI 需求的强类型 Schema。
+
+```rust
+/// 字段类型枚举
+#[derive(Debug, Clone, Serialize, Deserialize, ToSchema)]
+pub enum FieldType {
+    Text,       // 普通文本
+    Password,   // 密码/Token (前端掩码显示)
+    Url,        // URL 地址
+    Boolean,    // 开关
+    Select,     // 下拉选框 (需要 options)
+}
+
+/// 单个配置字段的定义
+#[derive(Debug, Clone, Serialize, Deserialize, ToSchema)]
+pub struct ConfigFieldSchema {
+    pub key: String,          // 字段键名 (如 "api_key")
+    pub label: String,        // 显示名称 (如 "API Token")
+    pub field_type: FieldType,// 字段类型
+    pub required: bool,       // 是否必填
+    pub placeholder: Option<String>, // 占位符
+    pub default_value: Option<String>, // 默认值
+    pub description: Option<String>,   // 字段说明
+}
+```
+
+### 2.2 服务元数据扩展 (Service Metadata Extension)
+
+修改 `ServiceRegistration` 并增加了 `ProviderMetadata` 结构。
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, ToSchema)]
+pub struct ProviderMetadata {
+    pub id: String,           // 服务ID (如 "tushare")
+    pub name_en: String,      // 英文名 (如 "Tushare Pro")
+    pub name_cn: String,      // 中文名 (如 "Tushare Pro (中国股市)")
+    pub description: String,  // 描述
+    pub icon_url: Option<String>, // 图标 (可选)
+    
+    /// 该服务需要的配置字段列表
+    pub config_schema: Vec<ConfigFieldSchema>,
+    
+    /// 是否支持“测试连接”功能
+    pub supports_test_connection: bool,
+}
+```
+
+## 3. 架构交互流程 (Architecture Flow)
+
+### 3.1 服务注册 (Registration Phase)
+1.  **Provider 启动** (如 `tushare-provider-service`):
+    *   构建 `ProviderMetadata`，声明自己需要 `api_key` (必填, Password) 和 `api_url` (选填, Url, 默认值...)。
+    *   调用 API Gateway 的 `/register` 接口，将 Metadata 发送给 Gateway。
+    
+2.  **API Gateway**:
+    *   在内存 Registry 中存储这些 Metadata。
+
+### 3.2 前端渲染 (Rendering Phase)
+1.  **前端请求**: `GET /v1/registry/providers` (网关聚合接口)。
+2.  **网关响应**: 返回所有活跃 Provider 的 `ProviderMetadata` 列表。
+3.  **前端请求**: `GET /v1/configs/data_sources` (获取用户已保存的配置值)。
+4.  **UI 生成**:
+    *   前端遍历 Metadata 列表。
+    *   对每个 Provider，根据 `config_schema` 动态生成 Input/Switch 组件。
+    *   将已保存的配置值填充到表单中。
+
+### 3.3 动作执行 (Action Phase)
+1.  **保存 (Save)**:
+    *   前端收集表单数据，发送标准 JSON 到 `POST /v1/configs/data_sources`。
+    *   后端持久化服务保存数据。
+
+2.  **测试连接 (Test Connection)**:
+    *   前端发送 `POST /v1/configs/test` (注意：Gateway已有通用接口)。
+    *   Payload: `{ type: "tushare", data: { "api_key": "..." } }`。
+    *   网关将请求路由到对应的 Provider 微服务进行自我检查。
+
+## 4. 任务拆解 (Task Breakdown)
+
+### 4.1 后端开发 (Backend Development) - [已完成/Completed]
+1.  **Common Contracts**: 更新 `registry.rs`，添加 `ProviderMetadata` 和 `ConfigFieldSchema` 定义。 (Done)
+2.  **API Gateway**:
+    *   更新注册逻辑，接收并存储 Metadata。 (Done)
+    *   新增接口 `GET /v1/registry/providers` 供前端获取元数据。 (Done)
+    *   **移除旧版接口**: 已删除 Legacy 的静态 schema 接口，强制转向动态机制。 (Done)
+    *   **单元测试**: 实现了 `ServiceRegistry` 的单元测试 (`registry_unit_test.rs`)，覆盖注册、心跳、发现、注销等核心逻辑。 (Done)
+3.  **Provider Services** (Tushare, Finnhub, etc.):
+    *   实现 `ConfigSchema` 的构建逻辑。 (Done)
+    *   更新注册调用，发送 Schema。 (Done for Tushare, Finnhub, AlphaVantage, YFinance)
+
+### 4.2 后端验证测试 (Backend Verification) - [已完成/Completed]
+在开始前端重构前，已进行一次集成测试，确保后端服务启动后能正确交互。
+
+1.  **启动服务**: 使用 `tests/api-e2e/run_registry_test.sh` 启动最小化服务集。
+2.  **API 验证**:
+    *   调用 `GET /v1/registry/providers`，验证返回的 JSON 是否包含所有 Provider 的 Metadata 和 Schema。
+    *   使用 `tests/api-e2e/registry_verifier.py` 脚本验证了 Tushare 的 Schema 字段正确性。
+3.  **结果确认**:
+    *   ✅ Tushare 服务成功注册。
+    *   ✅ Schema 正确包含 `api_token` (Password, Required)。
+    *   ✅ E2E 测试集 (`tests/end-to-end`) 也已更新并验证通过。
+
+### 4.3 前端重构 (Frontend Refactor) - [待办/Pending]
+1.  **API Client**: 更新 Client SDK 以支持新的元数据接口。
+    *   **自动化更新脚本**: `scripts/update_api_spec.sh`
+    *   **执行逻辑**: 
+        1.  调用 `cargo test ... generate_openapi_json` 生成 `openapi.json`。
+        2.  调用 `npm run gen:api` 重新生成前端 TypeScript 类型定义。
+    *   **输出位置**: `frontend/src/api/schema.gen.ts`
+2.  **State Management**: 修改 `useConfig` hook，增加获取 Provider Metadata 的逻辑。
+3.  **UI Refactor**:
+    *   废弃 `supportedProviders` 硬编码。
+    *   创建 `DynamicConfigForm` 组件，根据 `ConfigFieldSchema` 渲染界面。
+    *   对接新的测试连接和保存逻辑。

+# 重构任务：统一 Data Provider 工作流抽象
+
+## 1. 背景 (Background)
+
+目前的 Data Provider 服务（Tushare, YFinance, AlphaVantage 等）在架构上存在严重的重复代码和实现不一致问题。每个服务都独立实现了完整的工作流，包括：
+- NATS 消息接收与反序列化
+- 缓存检查与写入 (Cache-Aside Pattern)
+- 任务状态管理 (Observability/Task Progress)
+- Session Data 持久化
+- NATS 事件发布 (Success/Failure events)
+
+这种"散弹式"架构导致了以下问题：
+1.  **Bug 易发且难以统一修复**：例如 Tushare 服务因未执行 NATS Flush 导致事件丢失，而 YFinance 却因为实现方式不同而没有此问题。修复一个 Bug 需要在每个服务中重复操作。
+2.  **逻辑不一致**：不同 Provider 对缓存策略、错误处理、重试机制的实现可能存在细微差异，违背了系统的统一性。
+3.  **维护成本高**：新增一个 Provider 需要复制粘贴大量基础设施代码（Boilerplate），容易出错。
+
+## 2. 目标 (Objectives)
+
+贯彻 "Rustic" 的设计理念（强类型、单一来源、早失败），通过控制反转（IoC）和模板方法模式，将**业务逻辑**与**基础设施逻辑**彻底分离。
+
+- **单一来源 (Single Source of Truth)**：工作流的核心逻辑（缓存、持久化、通知）只在一个地方定义和维护。
+- **降低耦合**：具体 Provider 只需关注 "如何从 API 获取数据"，而无需关心 "如何与系统交互"。
+- **提升稳定性**：统一修复基础设施层面的问题（如 NATS Flush），所有 Provider 自动受益。
+
+## 3. 技术方案 (Technical Design)
+
+### 3.1 核心抽象 (The Trait)
+
+在 `common-contracts` 中定义纯粹的业务逻辑接口：
+
+```rust
+#[async_trait]
+pub trait DataProviderLogic: Send + Sync {
+    /// Provider 的唯一标识符 (e.g., "tushare", "yfinance")
+    fn provider_id(&self) -> &str;
+
+    /// 检查是否支持该市场 (前置检查)
+    fn supports_market(&self, market: &str) -> bool {
+        true
+    }
+
+    /// 核心业务：从外部源获取原始数据并转换为标准 DTO
+    /// 不涉及任何 DB 或 NATS 操作
+    async fn fetch_data(&self, symbol: &str) -> Result<(CompanyProfileDto, Vec<TimeSeriesFinancialDto>), anyhow::Error>;
+}
+```
+
+### 3.2 通用工作流引擎 (The Engine)
+
+实现一个泛型结构体或函数 `StandardFetchWorkflow`，封装所有基础设施逻辑：
+
+1.  **接收指令**：解析 `FetchCompanyDataCommand`。
+2.  **前置检查**：调用 `supports_market`。
+3.  **状态更新**：向 `AppState` 写入 "InProgress"。
+4.  **缓存层**：
+    *   检查 `persistence_client` 缓存。
+    *   HIT -> 直接返回。
+    *   MISS -> 调用 `fetch_data`，然后写入缓存。
+5.  **持久化层**：将结果写入 `SessionData`。

+# 重构任务：统一 Data Provider 工作流抽象
+
+## 1. 背景 (Background)
+
+目前的 Data Provider 服务（Tushare, YFinance, AlphaVantage 等）在架构上存在严重的重复代码和实现不一致问题。每个服务都独立实现了完整的工作流，包括：
+- NATS 消息接收与反序列化
+- 缓存检查与写入 (Cache-Aside Pattern)
+- 任务状态管理 (Observability/Task Progress)
+- Session Data 持久化
+- NATS 事件发布 (Success/Failure events)
+
+这种"散弹式"架构导致了以下问题：
+1.  **Bug 易发且难以统一修复**：例如 Tushare 服务因未执行 NATS Flush 导致事件丢失，而 YFinance 却因为实现方式不同而没有此问题。修复一个 Bug 需要在每个服务中重复操作。
+2.  **逻辑不一致**：不同 Provider 对缓存策略、错误处理、重试机制的实现可能存在细微差异，违背了系统的统一性。
+3.  **维护成本高**：新增一个 Provider 需要复制粘贴大量基础设施代码（Boilerplate），容易出错。
+
+## 2. 目标 (Objectives)
+
+贯彻 "Rustic" 的设计理念（强类型、单一来源、早失败），通过控制反转（IoC）和模板方法模式，将**业务逻辑**与**基础设施逻辑**彻底分离。
+
+- **单一来源 (Single Source of Truth)**：工作流的核心逻辑（缓存、持久化、通知）只在一个地方定义和维护。
+- **降低耦合**：具体 Provider 只需关注 "如何从 API 获取数据"，而无需关心 "如何与系统交互"。
+- **提升稳定性**：统一修复基础设施层面的问题（如 NATS Flush），所有 Provider 自动受益。
+
+## 3. 技术方案 (Technical Design)
+
+### 3.1 核心抽象 (The Trait)
+
+在 `common-contracts` 中定义纯粹的业务逻辑接口：
+
+```rust
+#[async_trait]
+pub trait DataProviderLogic: Send + Sync {
+    /// Provider 的唯一标识符 (e.g., "tushare", "yfinance")
+    fn provider_id(&self) -> &str;
+
+    /// 检查是否支持该市场 (前置检查)
+    fn supports_market(&self, market: &str) -> bool {
+        true
+    }
+
+    /// 核心业务：从外部源获取原始数据并转换为标准 DTO
+    /// 不涉及任何 DB 或 NATS 操作
+    async fn fetch_data(&self, symbol: &str) -> Result<(CompanyProfileDto, Vec<TimeSeriesFinancialDto>), anyhow::Error>;
+}
+```
+
+### 3.2 通用工作流引擎 (The Engine)
+
+实现一个泛型结构体或函数 `StandardFetchWorkflow`，封装所有基础设施逻辑：
+
+1.  **接收指令**：解析 `FetchCompanyDataCommand`。
+2.  **前置检查**：调用 `supports_market`。
+3.  **状态更新**：向 `AppState` 写入 "InProgress"。
+4.  **缓存层**：
+    *   检查 `persistence_client` 缓存。
+    *   HIT -> 直接返回。
+    *   MISS -> 调用 `fetch_data`，然后写入缓存。
+5.  **持久化层**：将结果写入 `SessionData`。
+6.  **事件通知**：
+    *   构建 `FinancialsPersistedEvent`。
+    *   发布 NATS 消息。
+    *   **关键：执行 `flush().await`。**
+7.  **错误处理**：统一捕获错误，发布 `DataFetchFailedEvent`，更新 Task 状态为 Failed。
+
+## 4. 执行步骤 (Execution Plan)
+
+1.  **基础设施准备**：
+    *   在 `services/common-contracts` 中添加 `DataProviderLogic` trait。
+    *   在 `services/common-contracts` (或新建 `service-kit` 模块) 中实现 `StandardFetchWorkflow`。
+
+2.  **重构 Tushare Service**：
+    *   创建 `TushareFetcher` 实现 `DataProviderLogic`。
+    *   删除 `worker.rs` 中的冗余代码，替换为对 `StandardFetchWorkflow` 的调用。
+    *   验证 NATS Flush 问题是否自然解决。
+
+3.  **重构 YFinance Service**：
+    *   同样方式重构，验证通用性。
+
+4.  **验证**：
+    *   运行 E2E 测试，确保数据获取流程依然通畅。
+
+## 5. 验收标准 (Acceptance Criteria)
+
+- `common-contracts` 中包含清晰的 Trait 定义。
+- Tushare 和 YFinance 的 `worker.rs` 代码量显著减少（预计减少 60%+）。
+- 所有 Provider 的行为（日志格式、状态更新频率、缓存行为）完全一致。
+- 即使不手动写 `flush`，重构后的 Provider 也能可靠发送 NATS 消息。

+# 设计方案 0: 系统总览与开发指南 (Overview & Setup)
+
+## 1. 项目背景 (Context)
+
+本项目是一个 **金融基本面分析系统 (Fundamental Analysis System)**。
+目标是通过自动化的工作流，从多个数据源（Tushare, YFinance）抓取数据，经过处理，最终生成一份包含估值、风险分析的综合报告。
+
+本次重构旨在解决原系统调度逻辑僵化、上下文管理混乱、大文件支持差的问题。我们将构建一个基于 **Git 内核** 的分布式上下文管理系统。
+
+## 2. 系统架构 (Architecture)
+
+系统由四个核心模块组成：
+
+1.  **VGCS (Virtual Git Context System)**: 底层存储。基于 Git + Blob Store 的版本化文件系统。
+2.  **DocOS (Document Object System)**: 逻辑层。提供“文档树”的裂变、聚合操作，屏蔽底层文件细节。
+3.  **Worker Runtime**: 适配层。提供 SDK 给业务 Worker（Python/Rust），使其能读写上下文。
+4.  **Orchestrator**: 调度层。负责任务分发、依赖管理和并行结果合并。
+
+```mermaid
+graph TD
+    subgraph "Storage Layer (Shared Volume)"
+        Repo[Git Bare Repo]
+        Blob[Blob Store]
+    end
+
+    subgraph "Library Layer (Rust Crate)"
+        VGCS[VGCS Lib] --> Repo & Blob
+        DocOS[DocOS Lib] --> VGCS
+    end
+
+    subgraph "Execution Layer"
+        Orch[Orchestrator Service] --> DocOS
+        Worker[Python/Rust Worker] --> Runtime[Worker Runtime SDK]
+        Runtime --> DocOS
+    end
+
+    Orch -- NATS (RPC) --> Worker
+```
+
+## 3. 技术栈规范 (Tech Stack)
+
+### 3.1 Rust (VGCS, DocOS, Orchestrator)
+*   **Version**: Stable (1.75+)
+*   **Key Crates**:
+    *   `git2` (0.18): libgit2 bindings. **注意**: 默认开启 `vendored-openssl` feature 以确保静态链接。
+    *   `serde`, `serde_json`: 序列化。
+    *   `thiserror`, `anyhow`: 错误处理。
+    *   `async-nats` (0.33): 消息队列。
+    *   `tokio` (1.0+): 异步运行时。
+    *   `sha2`, `hex`: 哈希计算。
+
+### 3.2 Python (Worker Runtime)
+*   **Version**: 3.10+
+*   **Package Manager**: Poetry
+*   **Key Libs**:
+    *   `nats-py`: NATS Client.
+    *   `pydantic`: 数据验证。
+    *   (可选) `libgit2-python`: 如果需要高性能 Git 操作，否则通过 FFI 调用 Rust Lib 或 Shell Out。
+
+## 4. 开发环境搭建 (Dev Setup)
+
+### 4.1 目录准备
+在本地开发机上，我们需要模拟共享存储。
+```bash
+mkdir -p /tmp/workflow_dev/repos
+mkdir -p /tmp/workflow_dev/blobs
+export WORKFLOW_DATA_PATH=/tmp/workflow_dev
+```
+
+### 4.2 Docker 环境
+为了确保一致性，所有服务应在 Docker Compose 中运行，挂载同一个 Volume。
+```yaml
+volumes:
+  workflow_data:
+
+services:
+  orchestrator:
+    image: rust-builder
+    volumes:
+      - workflow_data:/mnt/workflow_data
+    environment:
+      - WORKFLOW_DATA_PATH=/mnt/workflow_data
+```
+
+## 5. 模块集成方式
+*   **VGCS & DocOS**: 将实现为一个独立的 Rust Workspace Member (`crates/workflow-context`)。
+*   **Orchestrator**: 引用该 Crate。
+*   **Worker (Rust)**: 引用该 Crate。
+*   **Worker (Python)**: 通过 `PyO3` 绑定该 Crate，或者（MVP阶段）重写部分逻辑/Shell调用。**建议 MVP 阶段 Python SDK 仅封装 git binary 调用以简化构建**。
+
+## 6. 新人上手路径
+1.  阅读 `design_1_vgcs.md`，理解如何在不 clone 的情况下读写 git object。
+2.  阅读 `design_2_doc_os.md`，理解“文件变目录”的逻辑。
+3.  实现 Rust Crate `workflow-context` (包含 VGCS + DocOS)。
+4.  编写单元测试，验证 File -> Blob 的分流逻辑。
+5.  集成到 Orchestrator。

+# 设计方案 1: VGCS (Virtual Git Context System) [详细设计版]
+
+## 1. 定位与目标
+
+VGCS 是底层存储引擎，提供版本化、高性能、支持大文件的分布式文件系统接口。
+它基于 **git2-rs (libgit2)** 实现，直接操作 Git Object DB。
+
+## 2. 物理存储规范 (Specification)
+
+所有服务共享挂载卷 `/mnt/workflow_data`。
+
+### 2.1 目录结构
+```text
+/mnt/workflow_data/
+  ├── repos/
+  │   └── {request_id}.git/     <-- Bare Git Repo
+  │         ├── HEAD
+  │         ├── config
+  │         ├── objects/        <-- Standard Git Objects
+  │         └── refs/
+  └── blobs/
+      └── {request_id}/         <-- Blob Store Root
+            ├── ab/
+            │   └── ab1234...   <-- Raw File (SHA-256 of content)
+            └── cd/
+                └── cd5678...
+```
+
+### 2.2 Blob 引用文件格式 (.ref)
+当文件 > 1MB 时，Git Blob 存储如下 JSON 内容：
+```json
+{
+  "$vgcs_ref": "v1",
+  "sha256": "ab1234567890...", 
+  "size": 10485760,
+  "mime_type": "application/json",
+  "original_name": "data.json"
+}
+```
+
+## 3. 核心接口定义 (Rust Trait)
+
+### 3.1 ContextStore Trait
+
+```rust
+use anyhow::Result;
+use std::io::Read;
+
+pub trait ContextStore {
+    /// 初始化仓库
+    fn init_repo(&self, req_id: &str) -> Result<()>;
+
+    /// 读取文件内容
+    /// 自动逻辑：读取 Git Blob -> 解析 JSON -> 如果是 Ref，读 Blob Store；否则直接返回
+    fn read_file(&self, req_id: &str, commit_hash: &str, path: &str) -> Result<Box<dyn Read>>;
+
+    /// 读取目录
+    fn list_dir(&self, req_id: &str, commit_hash: &str, path: &str) -> Result<Vec<DirEntry>>;
+
+    /// 获取变更
+    fn diff(&self, req_id: &str, from_commit: &str, to_commit: &str) -> Result<Vec<FileChange>>;
+    
+    /// 三路合并 (In-Memory)
+    /// 返回新生成的 Tree OID，不生成 Commit
+    fn merge_trees(&self, req_id: &str, base: &str, ours: &str, theirs: &str) -> Result<String>;
+    
+    /// 创建写事务
+    fn begin_transaction(&self, req_id: &str, base_commit: &str) -> Result<Box<dyn Transaction>>;
+}
+
+#[derive(Debug)]
+pub struct DirEntry {
+    pub name: String,
+    pub kind: EntryKind, // File | Dir
+    pub object_id: String,
+}
+
+#[derive(Debug)]
+pub enum FileChange {
+    Added(String),
+    Modified(String),
+    Deleted(String),
+}
+```
+
+### 3.2 Transaction Trait (写操作)
+
+```rust
+pub trait Transaction {
+    /// 写入文件
+    /// 内部逻辑：
+    /// 1. 计算 content SHA-256
+    /// 2. if size > 1MB: 写 Blob Store，构造 Ref JSON
+    /// 3. 写 Git Blob (Raw 或 Ref)
+    /// 4. 更新内存中的 Index/TreeBuilder
+    fn write(&mut self, path: &str, content: &[u8]) -> Result<()>;
+
+    /// 删除文件
+    fn remove(&mut self, path: &str) -> Result<()>;
+
+    /// 提交更改
+    /// 1. Write Tree Object
+    /// 2. Create Commit Object (Parent = base_commit)
+    /// 3. Return new Commit Hash
+    fn commit(self, message: &str, author: &str) -> Result<String>;
+}
+```
+
+## 4. 实现细节规范
+
+### 4.1 读操作流程 (read_file)
+1.  Open Repo: `/mnt/workflow_data/repos/{req_id}.git`
+2.  Locate Tree: Parse `commit_hash` -> `tree_id`.
+3.  Find Entry: 在 Tree 中查找 `path`.
+4.  Read Blob: 读取 Git Blob 内容。
+5.  **Check Ref**: 尝试解析为 `BlobRef` 结构。
+    *   **Success**: 构建 Blob Store 路径 `/mnt/workflow_data/blobs/{req_id}/{sha256[0..2]}/{sha256}`，打开文件流。
+    *   **Fail** (说明是普通小文件): 返回 `Cursor::new(blob_content)`.
+
+### 4.2 写操作流程 (write)
+1.  Check Size: `content.len()`.
+2.  **Large File Path**:
+    *   Calc SHA-256.
+    *   Write to Blob Store (Ensure parent dir exists).
+    *   Content = JSON String of `BlobRef`.
+3.  **Git Write**:
+    *   `odb.write(Blob, content)`.
+    *   Update in-memory `git2::TreeBuilder`.
+
+### 4.3 合并流程 (merge_trees)
+1.  Load Trees: `base_tree`, `our_tree`, `their_tree`.
+2.  `repo.merge_trees(base, our, their, opts)`.
+3.  Check Conflicts: `index.has_conflicts()`.
+    *   If conflict: Return Error (Complex resolution left to Orchestrator Agent).
+4.  Write Result: `index.write_tree_to(repo)`.
+5.  Return Tree Hash.
+
+## 5. Web UI & Fuse
+*   **Web**: 基于 Axum，路由 `GET /api/v1/repo/:req_id/tree/:commit/*path`。复用 `ContextStore` 接口。
+*   **Fuse**: 基于 `fuser`。
+    *   Mount Point: `/mnt/vgcs_view/{req_id}/{commit}`.
+    *   `read()` -> `store.read_file()`.
+    *   `readdir()` -> `store.list_dir()`.
+    *   只读挂载，用于 Debug。
+
+## 6. 依赖库
+*   `git2` (0.18): 核心操作。
+*   `sha2` (0.10): 哈希计算。
+*   `serde_json`: Ref 序列化。
+*   `anyhow`: 错误处理。

+# 设计方案 2: DocOS (Document Object System) [详细设计版]
+
+## 1. 定位与目标
+
+DocOS 是构建在 VGCS 之上的逻辑层，负责处理文档结构的演进（裂变、聚合）。
+它不操作 Git Hash，而是操作逻辑路径。它通过 `ContextStore` 接口与底层交互。
+
+## 2. 数据结构定义
+
+### 2.1 逻辑节点 (DocNode)
+
+这屏蔽了底层是 `File` 还是 `Dir` 的差异。
+
+```rust
+#[derive(Debug, Serialize, Deserialize)]
+pub enum DocNodeKind {
+    Leaf,       // 纯内容节点 (对应文件)
+    Composite,  // 复合节点 (对应目录，含 index.md)
+}
+
+#[derive(Debug, Serialize, Deserialize)]
+pub struct DocNode {
+    pub name: String,
+    pub path: String, // 逻辑路径 e.g., "Analysis/Revenue"
+    pub kind: DocNodeKind,
+    pub children: Vec<DocNode>, // 仅 Composite 有值
+}
+```
+
+## 3. 核心接口定义 (DocManager Trait)
+
+```rust
+pub trait DocManager {
+    /// 基于最新的 Commit 重新加载状态
+    fn reload(&mut self, commit_hash: &str) -> Result<()>;
+
+    /// 获取当前文档树大纲
+    fn get_outline(&self) -> Result<DocNode>;
+
+    /// 读取节点内容
+    /// 逻辑：
+    /// - Leaf: 读 `path`
+    /// - Composite: 读 `path/index.md`
+    fn read_content(&self, path: &str) -> Result<String>;
+
+    // --- 写入操作 (Buffer Action) ---
+    
+    /// 写入内容 (Upsert)
+    /// 逻辑：
+    /// - 路径存在且是 Leaf -> 覆盖
+    /// - 路径存在且是 Composite -> 覆盖 index.md
+    /// - 路径不存在 -> 创建 Leaf
+    fn write_content(&mut self, path: &str, content: &str);
+
+    /// 插入子章节 (Implies Promotion)
+    /// 逻辑：
+    /// - 如果 parent 是 Leaf -> 执行 Promote (Rename Leaf->Dir/index.md) -> 创建 Child
+    /// - 如果 parent 是 Composite -> 直接创建 Child
+    fn insert_subsection(&mut self, parent_path: &str, name: &str, content: &str);
+
+    /// 提交变更
+    fn save(&mut self, message: &str) -> Result<String>;
+}
+```
+## 4. 关键演进逻辑 (Implementation Specs)
+
+### 4.1 裂变 (Promote Leaf to Composite)
+假设 `path = "A"` 是 Leaf (对应文件 `A`).
+Action `insert_subsection("A", "B")`:
+1.  Read content of `A`.
+2.  Delete file `A` (in transaction).
+3.  Write content to `A/index.md`.
+4.  Write new content to `A/B`.
+*注意*: Git 会将其视为 Delete + Add，或 Rename。VGCS 底层会处理。
+
+### 4.2 聚合 (Demote Composite to Leaf) - *Optional*
+假设 `path = "A"` 是 Composite (目录 `A/`).
+Action `demote("A")`:
+1.  Read `A/index.md`.
+2.  Concatenate children content (Optional policy).
+3.  Delete dir `A/`.
+4.  Write content to file `A`.
+
+### 4.3 路径规范
+*   **Root**: `/` (对应 Repo Root).
+*   **Meta**: `_meta.json` (用于存储手动排序信息，如果需要).
+*   **Content File**:
+    *   Leaf: `Name` (No extension assumption, or `.md` default).
+    *   Composite: `Name/index.md`.
+
+## 5. 实现依赖
+DocOS 需要持有一个 `Box<dyn Transaction>` 实例。
+所有的 `write_*` 操作都只是在调用 Transaction 的 `write`。
+只有调用 `save()` 时，Transaction 才会 `commit`。
+
+## 6. 错误处理
+*   `PathNotFound`: 读不存在的路径。
+*   `PathCollision`: 尝试创建已存在的文件。
+*   `InvalidOperation`: 尝试在 Leaf 节点下创建子节点（需显式调用 Promote 或 insert_subsection）。
