-## Development setup
-
-- **Runtime**: [Bun](https://bun.sh) >= 1.2.5
-- **Backend**: Hono (TypeScript)
-- **Frontend**: React + Vite + Tailwind CSS
-- **Database**: SQLite (via Drizzle ORM)
-
-```bash
-bun install                       # install all dependencies
-bun run dev                       # start dev server with hot reload
-```
-
-## Code quality
-
-```bash

-```
-
-Run all checks before pushing:
-
-```bash

-```
-
-## Pull requests
-
-1. Fork the repository and create a feature branch from `main`
-2. Make your changes with clear, atomic commits
-3. Ensure all quality checks pass (lint, build, test)
-4. Open a PR against `main` with a concise description of the change and motivation
-
-### Commit style
-
-Use [Conventional Commits](https://www.conventionalcommits.org/):
-
-```
-type(scope): subject
-
-feat(review): add size-based routing
-fix(webhook): handle missing signature header
-chore(deps): bump hono to 4.x
-docs(config): update env variable table
-```
-
-Common types: `feat`, `fix`, `chore`, `docs`, `refactor`, `test`.
-
-## UI development conventions
-
-The frontend follows a three-layer design token model:
-
-1. **Primitive** — HSL base values, defined only in global CSS tokens
-2. **Semantic** — `background`, `foreground`, `success`, `danger`, etc.
-3. **Component** — Components consume semantic tokens only. Direct primitive references are forbidden
-
-### Theme definition
-
-- Theme file: `frontend/src/index.css`
-- Tailwind mapping: `frontend/tailwind.config.js`
-- Primary palette: **Cobalt Blue**, with light/dark variants tuned for contrast
-
-Available palette presets (`data-palette` attribute): `cobalt` (default), `zinc`, `nord`, `tokyo-night`.
-
-### Hard rules
-
-- **No hardcoded dark-theme classes** in business TSX: `bg-zinc-*`, `text-zinc-*`, `border-white/10`, etc.
-- **No inline color values**: `rgba(...)`, `#xxxxxx`, `rgb(...)`
-- **Status colors use semantic tokens**: `success` / `warning` / `danger` / `info`
-- **Panels use semantic surface tokens**: `card`, `muted`, `popover`, `background`
-- **Interactive glow** uses utility classes: `theme-glow-primary|success|warning|danger`
-- **Non-primary hover** uses `hover:bg-accent*` or `hover:bg-muted*`. Only primary buttons may use `hover:bg-primary/90`
-
-### Recommended class patterns
-
-| Context | Classes |
-|---|---|
-| Text | `text-foreground` / `text-muted-foreground` |
-| Panel | `bg-card` / `bg-muted/50` / `bg-popover` |
-| Border | `border-border` / `theme-border-soft` |
-| Status | `text-success` / `bg-danger/10` / `border-warning/30` |
-| Hover (non-primary) | `hover:bg-accent/60` / `hover:bg-muted/60` |
-| Hover (primary action) | `hover:bg-primary/90` |
-| Page frame | `theme-page-frame` / `theme-page-actions` / `theme-page-content` |
-| Card | `theme-card-shell` / `theme-card-header` / `theme-card-content` |
-| Dialog | `theme-dialog-panel` / `theme-dialog-header` / `theme-dialog-body` / `theme-dialog-footer` |
-| Error state | `theme-error-panel` |
-| Sticky bar | `theme-sticky-bar` |
-| Input surface | `theme-input-surface` |
-| Control pill | `theme-control-pill` |
-
-### `destructive` vs `danger`
-
-- `destructive` — reserved for shadcn built-in destructive variant semantics
-- `danger` — business status semantics (errors, failures, risk indicators)
-
-New business components should prefer `danger` to avoid drift.
-
-### Pre-merge checklist
-
-- [ ] Page renders correctly in both light and dark themes
-- [ ] No `zinc`/`white` hardcoded dark-theme classes
-- [ ] No inline `style` color values
-- [ ] All status colors use semantic tokens
-- [ ] Components do not bypass the semantic layer to access primitive colors
-- [ ] `bun run ui:visual` passes (light/dark visual regression)
-
-### Visual regression
-
-- Generate/update baseline: `bun run ui:visual:update`
-- Verify baseline consistency: `bun run ui:visual`
-- Full UI check: `bun run ui:regression && bun run ui:visual`
-
-Baseline snapshots use Linux CI environment (`*-linux.png`). Cross-system snapshot updates introduce noise and should be avoided.

+## Architecture (high-level)
+
+```
+Gitea Webhook -> Gitea AI Assistant (Hono + Bun) -> LLM Gateway (multi-provider)
+                                 |
+                                 +-> Admin Dashboard (React)
+```
+
+For component-level design, see [Architecture docs](./docs/README.md#architecture--design).
+
+## Quick start (minimal)
+
+### 1) Prerequisites
+
+- Bun >= 1.2.5
+- Reachable Gitea instance
+- At least one LLM provider credential
+
+### 2) Install
 
 ```bash
-git clone https://github.com/jeffusion/gitea-ai-assistant.git
+git clone https://github.com/user/gitea-ai-assistant.git
 cd gitea-ai-assistant
-bun install                       # installs frontend via postinstall
+bun install
 ```
 
-Create `.env`:
+If lifecycle scripts are disabled in your environment, run:
 
 ```bash
-ENCRYPTION_KEY=$(openssl rand -hex 32)
+bun run bootstrap
 ```
 
+### 3) Minimal `.env`
+
+```bash
+PORT=5174
+ENCRYPTION_KEY=   # required, 64 hex chars (openssl rand -hex 32)
+# DATABASE_PATH=./data/assistant.db
+# LOG_LEVEL=info   # dev default; use LOG_LEVEL=error in production
+```
+
+> `ENCRYPTION_KEY` is mandatory. The app refuses to start without it.
+
+### 4) Run
+
 ```bash
 bun run dev
+# or
+bun run start
 ```
 
-Open `http://localhost:5174`, login with default password `password` (change it immediately), then configure Gitea, LLM providers, and webhook in the Admin UI.
+### 5) Configure in Admin UI
 
-See [Getting Started](./docs/getting-started.md) for full setup walkthrough including webhook configuration.
+Open `http://your-server:5174`, login with default `password` (first boot only), then change it immediately.

+| 系统类型 | AI 应用工程 / 后端 Agent Runtime / 审查系统适配层 |
+| 主要代码路径 | `src/agent-kernel/`、`src/review/kernel/` |
+| 相关配置 | `REVIEW_ENGINE=kernel` |
+
+### Assumptions
+
+- 当前项目已选择 **kernel-first** 作为代码审查主路径；旧固定 agent 编排不作为未来运行时主路径。
+- 内置 Agent 当前以 **built-in subagent definition** 的方式注册，后续可演进到 plugin/custom subagent 加载。
+- 一条 PR 对应一个 kernel session，commit 更新、人工反馈和后续恢复都写入同一 session。
+
+### To Be Confirmed
+
+- 是否需要把 built-in subagent 的定义从 TypeScript 代码进一步外置为 YAML/JSON/插件目录。
+- 管理后台是否需要支持逐 subagent 的启用/禁用、版本选择与灰度策略。
+
+---
+
+## 1. 背景与目标
+
+### 1.1 背景
+
+早期审查系统采用固定流程编排：triage 后按审查域派生多个 specialist，再由额外阶段汇总。该方案的问题是：
+
+- 流程扩展需要修改 orchestrator/runtime 代码；
+- 角色能力与执行链路耦合，难以按能力标签选择代理；
+- 缺少独立 subagent identity、delegation boundary 和 invocation trace；
+- 管理后台难以展示“有哪些 Agent、何时被调用、产生了什么结果”；
+- 恢复、压缩、权限、hook 等横切能力难以统一接入。
+
+新的 Kernel 内置 Agent 架构将 review 角色转换为注册式 built-in subagents，由 `AgentKernelRunner` 根据 planner 输出与 session state 推进任务，并通过 `KernelAgentInvoker` 统一委派执行。
+
+### 1.2 核心目标
+
+| 目标 | 说明 |
+|---|---|
+| 注册式扩展 | 内置 Agent 以 `KernelSubagentDefinition` 注册，runtime 不硬编码角色实例 |
+| 能力选择 | planner 通过 tags/capabilities 选择 subagent，而不是写死 agent id |
+| 可恢复执行 | session checkpoint 持久化 state + pendingTasks，支持 feedback 后继续执行 |
+| 委派边界 | 每次 subagent 调用都有 agentId、delegation packet、invocation record、structured result |
+| 上下文压缩 | 大上下文触发 compression，summary 写入 checkpoint 并回注后续 subagent |
+| 工具治理 | 工具调用走统一 orchestration、permission gating 与 hooks |
+| 可观测性 | 管理 API 暴露 task/subagent/hook catalog、session timeline、subagent invocations |
+
+### 1.3 范围与非范围
+
+**范围内**：
+
+- Review Kernel 内置 subagents 的定义、职责、标签、运行链路；
+- Kernel agent registry / invoker / runner 与 session checkpoint 的协作；
+- 内置 Agent 与 tools、hooks、permission、compression 的集成方式；
+- 管理后台需要消费的 catalog 与 session 投影视图；
+- 生产前自动化测试门禁。
+
+**范围外**：
+
+- 前端 UI 视觉设计细节；
+- 旧 `agent` 固定编排引擎兼容；
+- Codex CLI 引擎内部实现；
+- 通用插件市场、远程 agent 执行后端和多租户权限模型。
+
+---
+
+## 2. 设计原则与关键取舍
+
+### 2.1 核心设计原则
+
+| 原则 | 落地方式 |
+|---|---|
+| 高内聚低耦合 | `src/agent-kernel/` 只提供通用 session/runner/registry/invoker/hooks；review 逻辑放在 `src/review/kernel/` |
+| 开闭原则 | 新增流程能力优先增加 subagent、skill、hook 或 tool，而不是修改主循环 |
+| Session 为状态源 | PR/commit session 记录 event、checkpoint、subagent invocation，是恢复与投影的事实来源 |
+| 可观测优先 | 每次 subagent 调用持久化 invocation；每个 task 写入 started/completed/failed event |
+| 安全默认 | 工具执行统一经过 permission gating；高风险 scope 默认 ask/deny |
+| 可测试 | 断言面落在 checkpoint、events、invocations、tool result、admin projection，而不是完整 LLM 文本 |
+
+### 2.2 关键取舍
+
+| 取舍点 | 选择 | 原因 |
+|---|---|---|
+| 内置 Agent 表达方式 | TypeScript built-in definitions | 当前阶段需要强类型、低迁移成本；后续可迁移到 plugin loader |
+| Agent 调用入口 | `KernelAgentInvoker` 统一调用 | 统一 agentId、hook、invocation persistence、structured result |
+| 流程推进方式 | planner + session state | 避免静态任务数组；支持继续执行与人审恢复 |
+| Findings 处理 | 本地归一化、去重、排序与发布 | full review 只产出 findings；后续由 skill/本地逻辑保证确定性 |
+| 压缩策略 | planner 模型窗口 80% 触发 | 使用 tokenlens context window，预留 20% 冗余 |
+| 管理接口 | task/subagent/hook catalog + session detail | 让后台可解释当前能力目录与执行轨迹 |

+## 4. 内置 Agent 详细设计
+
+### 4.1 内置 Agent 目录
+
+| Subagent ID | Source | Model Role | Tags | 职责 | 触发条件 |
+|---|---|---|---|---|---|
+| `review:triage` | `built-in` | `planner` | `review`, `planner`, `triage` | 根据 diff、文件、风险生成自主审查提示、模式和预算 | build context 完成且尚无 triage 结果 |
+| `review:full_review` | `built-in` | `specialist` | `review`, `specialist`, `full-review`, `autonomous-review` | 执行一次完整自主代码审查，模型自行选择工具和调查路径 | triage 完成且尚未完成 full review |
+
+### 4.2 Subagent Definition 契约
+
+每个内置 Agent 必须实现 `KernelSubagentDefinition<TState>`：
+
+```typescript
+interface KernelSubagentDefinition<TState> {
+  kind: 'subagent';
+  name: string;
+  source: 'built-in' | 'custom' | 'plugin';
+  description: string;
+  whenToUse: string;
+  tags?: string[];
+  modelRole?: string;
+  resumable?: boolean;
+  execute(task, context): Promise<KernelHandlerResult<TState> | undefined>;
+}
+```
+
+关键约束：
+
+- `name` 必须稳定，作为 session event、invocation、admin catalog 的统一标识；
+- `tags` 必须包含能力标签，planner 只能按 tag/capability 选择代理；
+- `whenToUse` 既用于管理后台解释，也用于 delegation packet 的 goal；
+- `execute` 不直接控制主循环，只返回 state/enqueue/prepend/stopReason；
+- 内置 Agent 不应越权直接修改 pendingTasks，除非通过标准 `KernelHandlerResult`。
+
+### 4.3 Planner 选择规则
+
+`ReviewKernelRuntime.planTasks()` 根据 checkpoint state 推导下一步：
+
+```mermaid
+flowchart TD
+  A[开始 plan] --> B{有 pendingTasks?}
+  B -- 是 --> Z[不新增任务]
+  B -- 否 --> C{缺 workspace?}
+  C -- 是 --> PW[prepare_workspace skill]
+  C -- 否 --> D{缺 context?}
+  D -- 是 --> BC[build_context skill]
+  D -- 否 --> E{需要压缩?}
+  E -- 是 --> CC[compress_context skill]
+  E -- 否 --> F{缺 triage?}
+  F -- 是 --> T[按 tag=triage 选择 review:triage]
+  F -- 否 --> G{full review 未完成?}
+  G -- 是 --> S[执行 review:full_review]
+  G -- 否 --> P{未 publish?}
+  P -- 是 --> PR[publish_review skill]
+  P -- 否 --> R{未保存 reviewed ref?}
+  R -- 是 --> SR[save_reviewed_ref skill]
+  R -- 否 --> DONE[completed]
+```
+
+### 4.4 Triage Agent
+
+`review:triage` 包装 `TriageAgent`，输出自主审查提示：
+
+- 使用 `planner` 模型角色；
+- 接收 `projectPrompt` 和 `compressedContext.summary`；
+- 生成 `mode`、`reviewSize`、`riskTags`、`suspectedEntrypoints` 与预算提示；
+- 提示只影响 full review 的调查起点，不拆分审查任务。
+
+### 4.5 Autonomous Full Review Agent
+
+`review:full_review` 包装 `AutonomousReviewAgent`：
+
+- 共享 `ToolRegistry` 与 `KernelHookRegistry`；
+- 根据 `ReviewTask` 控制 mode、reviewSize、riskTags、suspectedEntrypoints、maxTurns、maxToolCalls、maxElapsedMs、tokenBudget；
+- 支持压缩 summary 回注到 prompt；
+- 不预拆 correctness/security/quality 子任务，模型在一次自主循环内跨文件调查；
+- 工具调用统一经过 tool orchestration、permission gating、Pre/Post tool hooks。
+
+### 4.6 Aggregate Findings Skill
+
+`aggregate_findings` 是 full review 后的确定性本地步骤：
+
+- 接收 `review:full_review` 产出的 findings；
+- 归一化 category/severity/confidence，补齐 fingerprint；
+- 按 fingerprint 去重，并按 severity/path/line/title 稳定排序；
+- 写回 checkpoint，供后续发布步骤使用。
+
+### 4.7 Publish and Save Skills
+
+`publish_review` 与 `save_reviewed_ref` 负责外部副作用：
+
+- `publish_review` 生成确定性 summary，并发布 PR summary 与 line comments；
+- `save_reviewed_ref` 在本地 mirror 保存已审查 ref，用于后续增量审查；
+- 两个步骤分离，避免评论发布和 ref 保存互相污染，失败时依赖 checkpoint 重试。
+

+## 4.8 Agent工作机制详解
+
+本节详细说明 Kernel Agent 的运转机制、任务调度、工具调用、决策逻辑及边界划分。
+
+### 4.8.1 核心运转架构
+
+Kernel 采用「**事件驱动 + 状态机**」的运行模式：
+
+```mermaid
+flowchart LR
+    Webhook[Gitea Webhook / Feedback] --> Engine[KernelReviewEngine]
+    Engine --> Session[Session Repository]
+    Engine --> Runtime[ReviewKernelRuntime]

+    Runner --> Planner[Turn Planner]
+    Planner --> Tasks[Tasks Queue]
+    Tasks --> Executor[Task Executor]
+    Executor --> State[State Update]
+    State --> Checkpoint[Checkpoint Save]
+    Checkpoint --> Runner
+```
+
+**关键组件职责**:
+
+| 组件 | 文件 | 核心职责 |
+|------|------|----------|
+| **AgentKernelRunner** | `agent-kernel-runner.ts` | 主循环控制器：任务调度、状态流转、checkpoint 管理 |
+| **ReviewKernelRuntime** | `review-kernel-runtime.ts` | Review 业务运行时：封装 skills、subagents、hooks、tools |
+| **KernelTurnPlanner** | `review-kernel-runtime.ts:305-361` | 基于当前 state 决定下一步执行什么任务 |
+
+### 4.8.2 核心运转流程
+
+**1. 启动阶段**:
+```typescript
+// PR webhook 触发
+kernelReviewEngine.enqueuePullRequest(payload)
+  → ensureSession(scopeKey)           // 创建或复用 session
+  → runtime.execute(run, sessionId) // 启动运行时
+  → AgentKernelRunner.run({          // 启动主循环
+      sessionId,
+      initialState: {...},
+      initialTasks: []
+    })
+```
+
+**2. 主循环机制** (`AgentKernelRunner.run`):
+
+```typescript
+async run({ sessionId, initialState, initialTasks, continueExisting }) {
+  // 从 checkpoint 恢复状态（支持继续执行）
+  const persisted = loadCheckpoint(sessionId);
+  let state = persisted?.state ?? initialState;
+  const pendingTasks = [...(persisted?.pendingTasks ?? initialTasks)];
+  
+  // 主循环：直到有 stopReason
+  while (!stopReason) {
+    // 如果没有待执行任务，让 planner 规划新任务
+    if (pendingTasks.length === 0) {
+      const planned = planner.plan({ session, state, pendingTasks });
+      pendingTasks.push(...planned);
+    }
+    
+    // 取出下一个任务
+    const task = pendingTasks.shift();
+    
+    // 执行任务
+    const result = await executeTask(task, context);
+    
+    // 处理执行结果
+    if (result?.state) state = result.state;              // 更新状态
+    if (result?.prepend) pendingTasks.unshift(...result.prepend);  // 前置任务
+    if (result?.enqueue) pendingTasks.push(...result.enqueue);        // 后置任务
+    if (result?.stopReason) stopReason = result.stopReason;          // 停止原因
+    
+    // 保存 checkpoint（支持失败恢复）
+    saveCheckpoint(sessionId, { state, pendingTasks, stopReason });
+  }
+}
+```
+
+**3. 恢复机制** (`continueExisting`):
+- 从 SQLite 加载持久化的 checkpoint
+- 恢复 `state` 和 `pendingTasks`
+- **显式忽略**旧 checkpoint 的 `stopReason`，允许从 feedback 后继续
+- 不 replay events，直接继续执行
+
+### 4.8.3 任务调度与决策
+
+**Planner 是决策中枢**，根据当前 state 动态决定下一步：
+
+```typescript
+private planTasks(context: KernelPlanningContext): KernelTask[] {
+  // 阶段1: 前置条件检查（顺序执行）
+  if (!context.state.workspacePath) {
+    return [{ kind: 'skill', name: 'prepare_workspace' }];
+  }
+  if (!context.state.context) {
+    return [{ kind: 'skill', name: 'build_context' }];
+  }
+  
+  // 阶段2: 上下文压缩决策
+  if (shouldCompress(context)) {
+    return [{ kind: 'skill', name: 'compress_context' }];
+  }
+  
+  // 阶段3: Triage 决策（生成自主审查提示）
+  if (!context.state.triage) {
+    return [{ kind: 'subagent', name: 'review:triage' }];
+  }
+   
+  // 阶段4: 单次完整自主审查
+  if (!context.state.reviewCompleted) {
+    return [{ kind: 'subagent', name: 'review:full_review' }];
+  }
+   
+  // 阶段5: 发布与收尾
+  if (!context.state.published) {
+    return [{ kind: 'skill', name: 'publish_review' }];
+  }
+  
+  return []; // 完成
+}
+```
+
+**决策依据**:
+- **当前 State**: `triage`, `reviewCompleted`, `findings`, `published`, `reviewedRefSaved` 等字段
+- **Tags/Capabilities**: 按标签选择 subagent（`filterByTag('triage')`），非硬编码
+- **Config 开关**: 审查引擎、工作区、命令白名单等运行配置
+
+### 4.8.4 Skills 与 Subagents 调用机制
+
+**Skills - 原子任务**:
+
+```typescript
+// 注册 Skills
+this.skillRegistry.register(createPrepareWorkspaceSkill());
+this.skillRegistry.register(createBuildContextSkill());
+
+// Skill 定义
+{
+  kind: 'skill',
+  name: 'build_context',
+  execute: async (task, context) => {
+    // 执行业务逻辑
+    const reviewContext = await diffExtractor.buildContext(...);
+    
+    return {
+      state: { ...context.state, context: reviewContext },  // 更新状态
+      // 可选控制流
+      prepend: [],      // 在当前任务前插入新任务
+      enqueue: [],      // 在当前任务后追加新任务
+      stopReason: undefined  // 或 'completed', 'failed', 'awaiting_human_feedback'
+    };
+  }
+}
+```
+
+**Subagents - 委派执行**:
+
+```typescript
+// 调用路径
+AgentKernelRunner → KernelAgentInvoker.invoke(task, context)
+  → 创建 invocation record
+  → 执行 subagent.execute(task, agentContext)
+  → 完成 invocation，返回结果
+```
+
+```typescript
+// Subagent 执行上下文
+const agentContext: KernelAgentExecutionContext = {
+  ...context,
+  agent,           // subagent 定义
+  delegation: {    // 委派包
+    goal: agent.whenToUse,
+    parentTaskName: task.name,
+    input: task.input,
+    contextSummary: state.compressedContext?.summary  // 压缩摘要回注
+  }
+};
+
+// 执行（带 AsyncLocalStorage 隔离）
+const result = await runWithKernelAgentContext(
+  { agentId, parentSessionId, agentType: 'subagent', ... },
+  () => agent.execute(task, agentContext)
+);
+```
+
+### 4.8.5 Tools 调用机制
+
+**调用路径**（在 `review:full_review` 内部）:
+
+```mermaid
+sequenceDiagram
+    participant FullReview as AutonomousReviewAgent
+    participant Loop as Autonomous Loop
+    participant Orchestration as ToolOrchestration
+    participant Permission as Permission Gating
+    participant Hook as PreToolUse Hook
+    participant Tool as Tool.execute()
+    participant PostHook as PostToolUse Hook
+
+    FullReview->>Loop: 决定调用 tool
+    Loop->>Orchestration: partitionToolCalls(tools)
+    Orchestration->>Permission: evaluateToolPermission(tool)
+    Permission-->>Orchestration: allow/ask/deny
+    Orchestration->>Hook: runKernelHooks(PreToolUse)
+    Hook-->>Orchestration: additionalContext/updatedInput
+    Orchestration->>Tool: tool.execute(args)
+    Tool-->>Orchestration: result
+    Orchestration->>PostHook: runKernelHooks(PostToolUse)
+    PostHook-->>Orchestration: -
+    Orchestration-->>Loop: toolResult
+    Loop-->>FullReview: 更新 diagnostics/findings
+```
+
+**并发控制**:
+- **并发安全工具** (`isConcurrencySafe: true`): 并行执行
+- **非并发安全工具**: 串行执行
+- **权限拦截**: `PermissionRequest` Hook 可批准/阻断
+
+**权限边界**:
+
+| Scope | 默认行为 | 说明 |
+|-------|----------|------|
+| `read` | `allow` | 安全操作（读文件、搜索代码） |
+| `write` | `ask` | 需审批（写文件） |
+| `command` | `ask` | 需审批（执行命令） |
+| `git_write` | `ask` | 需审批（Git 操作） |
+| `network` | `deny` | 禁止网络访问 |
+| `cross_session` | `deny` | 禁止跨 session 操作 |
+
+### 4.8.6 代码审查结合流程
+
+**完整数据流**:
+
+```
+Webhook → PR/Commit
+  ↓
+prepare_workspace → 克隆仓库、准备 mirror/workspace
+  ↓
+build_context → 提取 diff、文件内容、构建 ReviewContext
+  ↓
+compress_context (可选) → 大上下文自动压缩，生成 summary
+  ↓
+review:triage → 生成自主审查提示、模式和预算
+  ↓
+review:full_review → 单个自主代理跨文件调查，生成 findings
+  ↓
+publish_review → 发布 summary + line comments
+  ↓
+save_reviewed_ref → 保存审查快照（支持增量审查）
+```
+
+**状态流转**:
+
+```mermaid
+stateDiagram-v2
+    [*] --> prepare_workspace: 启动
+    prepare_workspace --> build_context: 成功
+    build_context --> compress_context: 上下文过大
+    build_context --> triage: 正常
+    compress_context --> triage: 完成
+    triage --> full_review: 提示生成完成
+    full_review --> publish_review: findings 聚合完成
+    publish_review --> save_reviewed_ref: 直接完成
+    save_reviewed_ref --> [*]: completed
+```
+
+### 4.8.7 边界划分
+
+**Skills vs Subagents 边界**:
+
+| 维度 | Skills | Subagents |
+|------|--------|-----------|
+| **粒度** | 原子操作（准备环境、构建上下文、发布） | 复杂推理（规划、完整审查） |
+| **模型** | 通常不涉及 LLM | 必须调用 LLM（planner/specialist） |
+| **并发** | 顺序执行 | 通过单个 full review 代理内部自主工具调用实现调查 |
+| **状态** | 修改 state 字段 | 可修改 state，主要产出 hints/findings/diagnostics |
+| **失败** | 阻断整个流程 | 可单独重试或降级 |
+| **示例** | prepare_workspace, publish_review | review:triage, review:full_review |
+
+**Runtime vs Runner 边界**:
+
+| 组件 | 职责 | 不做什么 |
+|------|------|----------|
+| **AgentKernelRunner** | 通用调度、checkpoint、task 循环 | 不感知 Review 业务逻辑 |
+| **ReviewKernelRuntime** | Review 业务封装、skills、subagents、hooks | 不直接调度任务（委托给 runner） |
+
+**Subagents 间边界**:
+
+| Subagent | 输入 | 输出 | 边界限制 |
+|----------|------|------|----------|
+| **triage** | ReviewContext | review hints + budget | 只生成提示，不审查 |
+| **full_review** | ReviewTask + context | findings[] + diagnostics | 一次完整自主审查，不预拆域或文件 |
+
+**Hook 介入边界**:
+
+```typescript
+// 在关键生命周期点介入
+SessionStart       // session 启动时
+SubagentStart      // subagent 启动时
+PreToolUse         // 工具调用前（可修改输入、阻断）
+PermissionRequest  // 权限请求时（决定 allow/ask/deny）
+PostToolUse        // 工具调用成功后
+PostToolUseFailure // 工具调用失败后
+```
+
+**Session 隔离边界**:
+
+- 每个 PR/Commit 对应独立 session
+- session 间 state 不共享
+- tool 默认禁止 cross_session 操作
+- subagent invocation 绑定 parentSessionId
+
+---
+
+## 5. 运行时与状态设计
+
+### 5.1 Session 与 Checkpoint
+
+每条 PR/commit 审查对应一个 kernel session：
+
+| 数据 | 用途 |
+|---|---|
+| `KernelSessionRecord` | 记录 scopeType、scopeKey、metadata、lastRunId |
+| `KernelSessionEventRecord` | append-only 事件流，记录 run/task/hook/feedback 生命周期 |
+| `KernelCheckpoint<TState>` | 持久化 state、pendingTasks、stopReason |
+| `KernelSubagentInvocationRecord` | 记录每次 subagent 委派调用 |
+
+恢复语义：
+
+- `continueExisting=true` 时从 persisted checkpoint 恢复 `state + pendingTasks`；
+- 显式忽略旧 checkpoint 的 stopReason，允许 feedback 后继续推进；
+- 当前不 replay session events 重建 state，event 主要用于投影与审计。
+
+### 5.2 ReviewKernelState
+
+核心状态包括：
+
+| 字段 | 说明 |
+|---|---|
+| `targetSha` | 当前审查目标 commit |
+| `mirrorPath/workspacePath` | 本地仓库与工作区路径 |
+| `context` | `ReviewContext`，包含 diff、changedFiles、fileContents 等 |
+| `projectPrompt` | 仓库级审查 prompt |
+| `compressedContext` | 自动压缩摘要及 token 元数据 |
+| `triage/reviewTask/reviewCompleted` | 自主审查提示、预算与完成状态 |
+| `findings` | subagents 收集到的问题 |
+| `reviewDiagnostics` | full review 工具调用、停止原因、解析计数等诊断信息 |
+| `published/reviewedRefSaved` | 发布与审查快照保存状态位 |
+
+### 5.3 Subagent Invocation
+
+每次 subagent 调用会持久化：
+
+| 字段 | 说明 |
+|---|---|
+| `parent_session_id` | 父 session |
+| `parent_run_id` | 当前 review run |
+| `parent_task_name` | 触发该调用的 task name |
+| `subagent_name` | subagent id，例如 `review:triage` |
+| `agent_id` | 本次调用唯一 agent identity |
+| `status` | running / completed / failed |
+| `input_json` | delegation packet |
+| `result_json` | structured invocation result |
+
+失败处理：
+
+- invoker 将 invocation 标记为 `failed`；
+- runner 写入 `task_failed` event；
+- checkpoint 保存当前 state 与 `[failedTask, ...pendingTasks]`，stopReason=`failed`；
+- 调用方可根据 checkpoint 与错误信息决定重试/人工介入。
+
+### 5.4 上下文压缩与回注
+
+```mermaid
+sequenceDiagram
+  participant P as Planner
+  participant C as ContextCompressionService
+  participant S as Session Checkpoint
+  participant A as Subagent
+
+  P->>C: shouldCompress(context, compressedContext)
+  C-->>P: true when tokenEstimate >= contextWindow * 0.8
+  P->>C: compress(context, projectPrompt)
+  C-->>S: compressedContext(summary, token stats, model, timestamp)
+  P->>A: invoke subagent with contextSummary
+  A-->>A: prompt includes compressed summary
+```
+
+压缩触发阈值：
+
+- 使用 `tokenCounter.getContextWindow(plannerModel)` 获取模型上下文窗口；
+- 取 80% 作为触发阈值，预留 20% 冗余；
+- 若无法获取模型配置，兜底使用默认窗口。
+
+### 5.5 Hooks 与 Permission
+
+内置 hooks：
+
+| Hook | Event | 作用 |
+|---|---|---|
+| `kernel:session-start-audit` | `SessionStart` | 写入 `hook_session_start` event |
+| `kernel:subagent-start-audit` | `SubagentStart` | 写入 `hook_subagent_start` event |
+| `kernel:pre-tool-audit` | `PreToolUse` | 为工具调用追加审计上下文 |
+| `kernel:permission-request-audit` | `PermissionRequest` | 记录权限请求上下文 |
+
+工具权限默认策略：
+
+| Scope | 默认行为 |
+|---|---|
+| `read` | allow |
+| `write` | ask |
+| `command` | ask |
+| `git_write` | ask |
+| `network` | deny |
+| `cross_session` | deny |
+
+---
+
+## 6. API 与管理后台可观测性
+
+### 6.1 Admin API
+
+| API | 说明 |
+|---|---|
+| `GET /admin/api/review/sessions` | 返回 session 列表与 summary |
+| `GET /admin/api/review/sessions/:sessionId` | 返回 session、summary、checkpoint、plan、timeline、events、subagentInvocations、runDetails |
+| `GET /admin/api/review/kernel/tasks` | 返回 skill + subagent task catalog |
+| `GET /admin/api/review/kernel/subagents` | 返回 subagent catalog |
+| `GET /admin/api/review/kernel/hooks` | 返回 hook catalog |
+
+### 6.2 Subagent Catalog 响应字段
+
+```json
+{
+  "kind": "subagent",
+  "name": "review:full_review",
+  "source": "built-in",
+  "description": "执行一次完整自主代码审查",
+  "whenToUse": "当 triage 生成审查提示后执行完整审查",
+  "modelRole": "specialist",
+  "tags": ["review", "specialist", "full-review", "autonomous-review"],
+  "resumable": true
+}
+```
+
+### 6.3 管理后台展示建议
+
+管理后台应采用双层控制面：
+
+- 上层：Kernel Subagents 目录，展示 built-in/custom/plugin subagents；
+- 下层：模型角色路由，配置 `planner / specialist` 到 provider/model。
+
+展示字段建议：
+
+| 区域 | 字段 |
+|---|---|
+| Subagent 目录 | name、source、description、whenToUse、modelRole、tags、resumable |
+| Session 详情 | summary、plan、timeline、findings、comments、subagentInvocations |
+| Invocation 详情 | agentId、status、startedAt、finishedAt、summary、artifacts |
+
+---
+
+## 7. 非功能性设计
+
+### 7.1 安全设计
+
+- 工具调用统一走 permission gating，避免 subagent 绕过权限策略；
+- 高风险工具默认 ask/deny，不允许直接执行网络、跨 session 或写操作；
+- hooks 可作为后续审批、审计、通知与策略扩展点；
+- LLM prompt 不作为安全边界，所有外部副作用必须由 tool/skill/adapters 承载。
+
+### 7.2 高可用与恢复
+
+- 每个 task 完成后保存 checkpoint，降低失败后的重复工作；
+- subagent invocation 失败会记录 failed 状态，便于定位失败代理；
+- feedback 后通过 `continueExisting` 从 checkpoint 继续；
+- publish 与 save reviewed ref 分离，避免评论发布与 ref 保存互相污染；
+- cleanup workspace 放在 runtime finally 中执行，降低资源泄漏风险。
+
+### 7.3 可观测性
+
+- session event 记录 run/task/hook/feedback 生命周期；
+- subagent invocation 记录 parent-child 委派关系；
+- admin projection 汇总 plan/timeline/currentStep/findingCount/pendingTaskCount；
+- compression 记录 sourceTokenEstimate、summaryTokenEstimate、triggerThreshold、model。
+
+### 7.4 性能与容量
+
+- 大 diff 先经 diff extractor/token budget 裁剪，再由 compression service 做会话级摘要；
+- `review:full_review` 在单个自主循环内使用工具逐步调查，避免运行时预拆 domain 或文件；
+- tool orchestration 可并发执行 read-only 工具，非并发安全工具串行；
+- session/event/checkpoint 使用 SQLite，适合当前单体部署；未来高并发可迁移到外部数据库。
+
+### 7.5 可维护性与扩展性
+
+- 新增内置 Agent 应只新增 `KernelSubagentDefinition` 并打 tags；
+- 新增流程副作用应优先实现 skill/adapters；
+- 新增横切逻辑应优先实现 hook；
+- 新增工具必须声明 permissionScope 和 isConcurrencySafe。
+
+---
+
+## 8. 测试与上线验证
+
+### 8.1 自动化测试分层
+
+| 层级 | 测试文件 | 覆盖点 |
+|---|---|---|
+| Unit | `src/review/kernel/__tests__/session-read-model.test.ts` | session summary/plan/timeline 投影 |
+| Unit | `src/review/tools/__tests__/tool-permissions.test.ts` | permission scope 默认策略 |
+| Contract | `src/agent-kernel/hooks/__tests__/kernel-hook-runner.test.ts` | hook 聚合、approve/block、updatedInput |
+| Integration | `src/controllers/__tests__/admin-review-sessions.test.ts` | admin session 与 catalog API |
+| Integration | `src/controllers/__tests__/feedback-kernel-session.test.ts` | feedback approve/reject/rollback/continue |
+| Runtime | `src/review/kernel/__tests__/runtime-happy-path.test.ts` | 完整 runtime happy path |
+| Runtime | `src/review/kernel/__tests__/runtime-feedback-resume.test.ts` | awaiting feedback 后恢复 |
+| Runtime | `src/review/kernel/__tests__/runtime-replay-invariants.test.ts` | checkpoint/resume/replay 不变量 |
+| Runtime | `src/review/kernel/__tests__/runtime-concurrency-idempotency.test.ts` | 并发上限与幂等 |
+| Canary | `src/review/kernel/__tests__/compression-resumability.test.ts` | 压缩恢复与生产关键 canary |
+
+### 8.2 上线前门禁
+
+必须通过：
+
+```bash
+bun run lint
+bun run build
+bun test src/review/kernel/__tests__ src/review/tools/__tests__ src/controllers/__tests__ src/agent-kernel/hooks/__tests__
+bun test
+```
+
+关键验收信号：
+
+- runtime happy path 完成，stopReason=`completed`；
+- feedback resume 从 `awaiting_human_feedback` 恢复到 completed；
+- compression resume 保留 targetSha、pending boundary、invocation boundary、summary；
+- permission deny 不会绕过工具治理；
+- duplicate enqueue/continue/feedback 不产生重复有效工作；
+- admin session detail 能看到 plan/timeline/subagentInvocations。
+
+### 8.3 灰度与回滚
+
+- 配置默认：`REVIEW_ENGINE=kernel`；
+- 若需要回滚，可临时切到 `codex` 引擎，但旧固定 agent 编排不再作为主路径；
+- 灰度期间重点观察 session stopReason 分布、task_failed 事件、subagent failed invocations、feedback resume 成功率。
+
+---
+
+## 9. 风险、待确认与后续演进
+
+### 9.1 风险与应对
+
+| 风险 | 影响 | 应对 |
+|---|---|---|
+| Built-in definitions 仍在代码中 | 扩展仍需发版 | 下一阶段引入 plugin/custom subagent loader |
+| SQLite 单文件并发能力有限 | 高并发 session 下写入竞争 | 当前单体可接受；未来迁移外部 DB 或队列化写入 |
+| Compression summary 可能遗漏细节 | 后续 subagent 判断偏差 | 保留 recent context + summary；测试锁定关键事实不丢 |
+| Hook 阻断策略过强或过弱 | 工具误阻断或越权 | permission matrix 测试 + 审计 event + 管理后台策略展示 |
+
+### 9.2 后续演进计划
+
+1. **Plugin-based Subagent Loading**：支持从目录或配置加载 custom/plugin subagents。
+2. **Child Session Tree**：为长任务或后台 subagent 引入 child session/resume tree。
+3. **Attachment Reinjection**：压缩后恢复文件附件、计划附件和技能附件。
+4. **更细粒度权限模型**：支持仓库级、工具级、用户级策略配置。
+5. **Subagent 版本治理**：为 built-in/custom/plugin subagents 增加 version、enabled、rollout 字段。
+
+### 9.3 评审清单
+
+- [ ] 内置 Agent 是否都通过 registry/invoker 调用，而不是 runtime 硬编码实例？
+- [ ] planner 是否按 tag/capability 选择 subagent？
+- [ ] 每次 subagent 调用是否有 invocation record？
+- [ ] feedback 后 continue 是否从 checkpoint 恢复？
+- [ ] 压缩 summary 是否持久化并回注 triage/full_review？
+- [ ] 工具执行是否经过 permission/hook/orchestration？
+- [ ] 管理后台是否能展示 catalog、timeline、invocations？
+- [ ] 生产测试门禁是否覆盖 happy path、失败恢复、幂等和 canary？

+# 通知服务抽象化重构方案
+
+## 1. 概述
+
+### 1.1 背景
+当前项目中的通知功能仅支持飞书(Feishu/Lark)平台，代码高度耦合飞书特定的API实现。随着业务需求扩展，需要支持企业微信(WeCom)等其他通知渠道。
+
+### 1.2 目标
+- 抽象通用通知服务接口，支持多平台扩展
+- 支持同时配置多个通知服务（如飞书+企业微信同时推送）
+- 统一通知调用入口，避免平台耦合与重复发送
+- 清晰的代码结构，便于后续添加新平台（如Slack、钉钉等）
+
+### 1.3 非目标
+- 不修改通知的业务触发逻辑
+- 不改变现有的Gitea Webhook处理流程
+- 不引入外部通知服务SDK依赖（保持轻量）
+
+---
+
+## 2. 现有架构分析
+
+### 2.1 重构前实现（已下线）
+```
+src/
+├── services/feishu.ts          # 飞书服务实现（156行）
+├── controllers/review.ts       # 通知调用点
+├── config/config-schema.ts     # 配置定义
+└── config/config-manager.ts    # 配置管理
+```
+
+### 2.2 关键代码特征
+- **强耦合**：`review.ts` 直接调用 `feishuService.sendXXXNotification()`
+- **硬编码消息格式**：飞书特定的 `msg_type: 'text'` 结构
+- **签名逻辑**：HMAC-SHA256(timestamp+"\n"+secret)
+- **配置单一**：仅支持一组飞书配置
+
+### 2.3 通知场景
+| 场景 | 方法名 | 触发条件 |
+|------|--------|----------|
+| 工单创建 | `sendIssueCreatedNotification` | Issue opened + 有指派人 |
+| 工单关闭 | `sendIssueClosedNotification` | Issue closed |
+| 工单指派 | `sendIssueAssignedNotification` | Issue assigned |
+| PR创建 | `sendPrCreatedNotification` | PR opened + 有审阅者 |
+| PR指派 | `sendPrReviewerAssignedNotification` | PR review_requested |

+```
+
+### 3.2 核心接口设计
+
+#### 3.2.1 类型定义
+```typescript
+// types.ts
+export type NotificationProvider = 'feishu' | 'wecom' | 'slack' | 'dingtalk';
+
+export interface NotificationContext {
+  // PR相关
+  prTitle?: string;
+  prUrl?: string;
+  prNumber?: number;
+  
+  // Issue相关
+  issueTitle?: string;
+  issueUrl?: string;
+  issueNumber?: number;
+  
+  // 用户相关
+  actor?: string;
+  assignees?: string[];
+  reviewers?: string[];
+  creator?: string;
+  
+  // 仓库相关
+  repository?: string;
+  owner?: string;
+  
+  // 时间戳
+  timestamp?: Date;
+}
+
+export interface NotificationMessage {
+  type: 'text' | 'markdown';
+  title?: string;
+  content: string;
+  atUsers?: string[];
+  url?: string;
+}
+```
+
+#### 3.2.2 服务接口
+```typescript
+// INotificationService
+export interface INotificationService {
+  readonly provider: NotificationProvider;
+  
+  isEnabled(): boolean;
+  sendMessage(message: NotificationMessage): Promise<void>;
+  
+  // 场景特定方法
+  sendIssueCreatedNotification(context: NotificationContext): Promise<void>;
+  sendIssueClosedNotification(context: NotificationContext): Promise<void>;
+  sendIssueAssignedNotification(context: NotificationContext): Promise<void>;
+  sendPrCreatedNotification(context: NotificationContext): Promise<void>;
+  sendPrReviewerAssignedNotification(context: NotificationContext): Promise<void>;
+}
+```
+
+### 3.3 平台差异对照
+
+| 特性 | 飞书(Feishu) | 企业微信(WeCom) | Slack |
+|------|--------------|-----------------|-------|
+| **Webhook格式** | `open.feishu.cn/open-apis/bot/v2/hook/{key}` | `qyapi.weixin.qq.com/cgi-bin/webhook/send?key={key}` | `hooks.slack.com/services/...` |
+| **签名机制** | HMAC-SHA256(timestamp+"\n"+secret) | **无** | HMAC-SHA256(timestamp+":"+secret) |
+| **@用户方式** | `<at user_id="xxx">` 或文本追加 | `mentioned_list: ["userid"]` 或手机号 | `<@user_id>` |
+| **消息类型字段** | `msg_type` | `msgtype` | `type` |
+| **内容字段** | `content.text` | `text.content` | `text` |
+| **频率限制** | 100次/分钟 | 20条/分钟 | 1次/秒 |

+```
+
+### 4.2 基类实现
+
+```typescript
+// base-notification-service.ts
+export abstract class BaseNotificationService implements INotificationService {
+  abstract readonly provider: NotificationProvider;
+  
+  constructor(protected config: NotificationServiceConfig) {}
+  
+  isEnabled(): boolean {
+    return this.config.enabled && !!this.config.webhookUrl;
+  }
+  
+  abstract sendMessage(message: NotificationMessage): Promise<void>;
+  
+  // 通用模板方法
+  async sendIssueCreatedNotification(context: NotificationContext): Promise<void> {
+    const message = this.buildIssueCreatedMessage(context);
+    await this.sendMessage(message);
+  }
+  
+  // 子类实现消息构建
+  protected abstract buildIssueCreatedMessage(context: NotificationContext): NotificationMessage;
+  // ... 其他方法类似
+}
+```
+
+### 4.3 飞书实现要点
+
+```typescript
+// feishu-notification-service.ts
+export class FeishuNotificationService extends BaseNotificationService {
+  readonly provider = 'feishu' as const;
+  
+  async sendMessage(message: NotificationMessage): Promise<void> {
+    const payload: any = {
+      msg_type: 'text',
+      content: {
+        text: message.content,
+      },
+    };
+    
+    // 添加签名
+    if (this.config.webhookSecret) {
+      const timestamp = Math.floor(Date.now() / 1000).toString();
+      payload.timestamp = timestamp;
+      payload.sign = this.generateSign(timestamp, this.config.webhookSecret);
+    }
+    
+    const response = await fetch(this.config.webhookUrl, {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify(payload),
+    });
+    
+    if (!response.ok) {
+      throw new Error(`Feishu notification failed: ${response.statusText}`);
+    }
+  }
+  
+  protected buildIssueCreatedMessage(context: NotificationContext): NotificationMessage {
+    return {
+      type: 'text',
+      content: `📝 新工单已创建\n标题: ${context.issueTitle}\n链接: ${context.issueUrl}`,
+      atUsers: context.assignees,
+    };
+  }
+  
+  private generateSign(timestamp: string, secret: string): string {
+    const stringToSign = `${timestamp}\n${secret}`;
+    const hmac = crypto.createHmac('sha256', stringToSign);
+    return hmac.digest('base64');
+  }
+}
+```
+
+### 4.4 企业微信实现要点
+
+```typescript
+// wecom-notification-service.ts
+export class WeComNotificationService extends BaseNotificationService {
+  readonly provider = 'wecom' as const;
+  
+  async sendMessage(message: NotificationMessage): Promise<void> {
+    const payload: any = {
+      msgtype: 'text',
+      text: {
+        content: message.content,
+      },
+    };
+    
+    // 企业微信使用 mentioned_list
+    if (message.atUsers?.length) {
+      payload.text.mentioned_list = message.atUsers.map(u => 
+        u.toLowerCase() === 'all' ? '@all' : u
+      );
+    }
+    
+    const response = await fetch(this.config.webhookUrl, {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify(payload),
+    });
+    
+    if (!response.ok) {
+      throw new Error(`WeCom notification failed: ${response.statusText}`);
+    }
+  }
+  
+  protected buildIssueCreatedMessage(context: NotificationContext): NotificationMessage {
+    return {
+      type: 'text',
+      content: `📝 新工单已创建\n标题: ${context.issueTitle}\n链接: ${context.issueUrl}`,
+      atUsers: context.assignees,
+    };
+  }
+}
+```
+
+### 4.5 管理器实现
+
+```typescript
+// notification-manager.ts
+export class NotificationManager {
+  private services: INotificationService[] = [];
+  
+  constructor(configs: NotificationServiceConfig[]) {
+    this.services = configs
+      .filter(c => c.enabled && c.webhookUrl)
+      .map(c => NotificationFactory.createService(c));
+  }
+  
+  // 广播到所有服务
+  async broadcast(
+    operation: (service: INotificationService) => Promise<void>
+  ): Promise<void> {
+    const results = await Promise.allSettled(
+      this.services.map(async service => {
+        try {
+          await operation(service);
+        } catch (error) {
+          logger.error(`${service.provider} notification failed:`, error);
+          throw error; // 重新抛出以便Promise.allSettled捕获
+        }
+      })
+    );
+    
+    // 记录失败统计
+    const failures = results.filter(r => r.status === 'rejected');
+    if (failures.length > 0) {
+      logger.warn(`${failures.length}/${this.services.length} notification services failed`);
+    }
+  }
+  
+  // 便捷方法
+  async notifyIssueCreated(context: NotificationContext): Promise<void> {
+    await this.broadcast(s => s.sendIssueCreatedNotification(context));
+  }
+  
+  async notifyIssueClosed(context: NotificationContext): Promise<void> {
+    await this.broadcast(s => s.sendIssueClosedNotification(context));
+  }
+  
+  async notifyIssueAssigned(context: NotificationContext): Promise<void> {
+    await this.broadcast(s => s.sendIssueAssignedNotification(context));
+  }
+  
+  async notifyPrCreated(context: NotificationContext): Promise<void> {
+    await this.broadcast(s => s.sendPrCreatedNotification(context));
+  }
+  
+  async notifyPrReviewerAssigned(context: NotificationContext): Promise<void> {
+    await this.broadcast(s => s.sendPrReviewerAssignedNotification(context));
+  }
+}
+```
+
+---
+
+## 5. 配置改造
+
+### 5.1 新增配置字段
+
+```typescript
+// config-schema.ts
+export const CONFIG_FIELDS: ConfigFieldMeta[] = [
+  // ... 保留原有 ...
+  
+  // 飞书配置（改造为可独立启用）
+  {
+    envKey: 'FEISHU_ENABLED',
+    group: 'notification',
+    label: '启用飞书通知',
+    description: '是否启用飞书通知',
+    type: 'boolean',
+    sensitive: false,
+    defaultValue: true,
+  },
+  {
+    envKey: 'FEISHU_WEBHOOK_URL',
+    group: 'notification',
+    label: '飞书 Webhook 地址',
+    description: '飞书机器人 Webhook URL',
+    type: 'url',
+    sensitive: false,
+  },
+  {
+    envKey: 'FEISHU_WEBHOOK_SECRET',
+    group: 'notification',
+    label: '飞书 Webhook 密钥',
+    description: '飞书 Webhook 签名密钥（可选）',
+    type: 'string',
+    sensitive: true,
+  },
+  
+  // 企业微信配置（新增）
+  {
+    envKey: 'WECOM_ENABLED',
+    group: 'notification',
+    label: '启用企业微信通知',
+    description: '是否启用企业微信通知',
+    type: 'boolean',
+    sensitive: false,
+    defaultValue: false,
+  },
+  {
+    envKey: 'WECOM_WEBHOOK_URL',
+    group: 'notification',
+    label: '企业微信 Webhook 地址',
+    description: '企业微信机器人 Webhook URL',
+    type: 'url',
+    sensitive: false,
+  },
+];
+```
+
+### 5.2 配置组调整
+
+```typescript
+// 将 'feishu' 组改为 'notification' 组
+export type ConfigGroup = 'gitea' | 'notification' | 'security' | 'review' | 'memory';
+
+export const CONFIG_GROUPS: ConfigGroupMeta[] = [
+  // ...
+  {
+    key: 'notification',
+    label: '通知服务',
+    description: '飞书、企业微信等通知渠道配置',
+    icon: 'bell',
+  },
+  // ...
+];
+```
+
+---
+
+## 6. 调用层迁移
+
+### 6.1 review.ts 改造
+
+```typescript
+import { getNotificationManager } from '../services/notification-manager';
+
+// PR事件处理
+async function handlePullRequestEvent(c: Context, body: any): Promise<Response> {
+  // ... 原有逻辑 ...
+  
+  const context: NotificationContext = {
+    prTitle: pullRequest.title,
+    prUrl: pullRequest.html_url,
+    prNumber: pullRequest.number,
+    reviewers: reviewerUsernames,
+    repository: repo.name,
+    owner: repo.owner.login,
+    actor: body.sender?.login,
+  };
+  
+  const notificationManager = getNotificationManager();
+
+  if (body.action === 'opened' && reviewerUsernames.length > 0) {
+    await notificationManager.notifyPrCreated(context);
+  }
+  
+  if (body.action === 'review_requested' && body.requested_reviewer) {
+    context.assignees = [body.requested_reviewer.full_name || body.requested_reviewer.login];
+    await notificationManager.notifyPrReviewerAssigned(context);
+  }
+  
+  // ... 继续原有逻辑 ...
+}
+
+// Issue事件处理
+async function handleIssueEvent(c: Context, body: any): Promise<Response> {
+  // ...
+  
+  const context: NotificationContext = {
+    issueTitle: issue.title,
+    issueUrl: issue.html_url,
+    issueNumber: issue.number,
+    creator: creatorUsername,
+    assignees: assigneeUsernames,
+    repository: repository.name,
+    actor: body.sender?.login,
+  };
+  
+  if (action === 'opened' && assigneeUsernames.length > 0) {
+    await notificationManager.notifyIssueCreated(context);
+  } else if (action === 'closed') {
+    await notificationManager.notifyIssueClosed(context);
+  } else if (action === 'assigned') {
+    await notificationManager.notifyIssueAssigned(context);
+  }
+}
+```
+

+
+## 7. 落地决策（已执行）
+
+### 7.1 旧飞书服务下线
+
+- 已删除 `src/services/feishu.ts`，不再保留兼容层。
+- `src/controllers/review.ts` 中所有通知发送路径已统一到 `NotificationManager`。
+- 通过单一通知入口避免重复发送与配置路径分裂问题。
+
+### 7.2 运行时配置生效策略
+
+- 通知管理器按当前配置即时创建，不再使用长生命周期缓存。
+- 后台保存通知配置后，可立即在后续 webhook 事件生效。
+
+### 7.3 落地检查清单
+
+- [x] 飞书与企业微信通过统一通知抽象发送
+- [x] 旧飞书服务文件已下线
+- [x] 控制器通知链路已去重
+- [x] 前端新增独立“通知管理”菜单与页面
+
+---
+
+## 8. 实施计划
+
+### 8.1 阶段划分
+
+| 阶段 | 任务 | 文件 | 优先级 |
+|------|------|------|--------|
+| 1 | 核心抽象层 | `types.ts`, `base-notification-service.ts` | P0 |
+| 2 | 工厂与管理器 | `notification-factory.ts`, `notification-manager.ts` | P0 |
+| 3 | 飞书实现 | `providers/feishu-notification-service.ts` | P1 |
+| 4 | 企业微信实现 | `providers/wecom-notification-service.ts` | P1 |
+| 5 | 配置改造 | `config-schema.ts`, `config-manager.ts` | P1 |
+| 6 | 调用层迁移 | `review.ts` | P1 |
+| 7 | 前端通知管理页面 | `App.tsx`, `DashboardPage.tsx`, `NotificationConfigPage.tsx` | P1 |
+| 8 | 测试验证 | `config-manager.test.ts` 等 | P0 |
+
+### 8.2 风险与缓解
+
+| 风险 | 影响 | 缓解措施 |
+|------|------|----------|
+| 签名算法变更 | 飞书通知失效 | 保持原有签名实现，单元测试覆盖 |
+| 配置迁移失败 | 服务无法启动 | 添加配置验证和默认值回退 |
+| 多服务并发失败 | 部分通知丢失 | Promise.allSettled 确保独立性 |
+
+---
+
+## 9. 测试策略
+
+### 9.1 单元测试
+
+```typescript
+// __tests__/notification.test.ts
+describe('NotificationService', () => {
+  describe('FeishuNotificationService', () => {
+    it('should generate correct signature', () => {
+      // 测试签名算法
+    });
+    
+    it('should format message correctly', () => {
+      // 测试消息格式转换
+    });
+  });
+  
+  describe('WeComNotificationService', () => {
+    it('should use mentioned_list for @users', () => {
+      // 测试@用户格式
+    });
+  });
+  
+  describe('NotificationManager', () => {
+    it('should broadcast to all enabled services', async () => {
+      // 测试广播逻辑
+    });
+    
+    it('should not fail if one service fails', async () => {
+      // 测试容错
+    });
+  });
+});
+```
+
+### 9.2 集成测试
+
+- 配置真实飞书机器人测试消息发送
+- 配置企业微信机器人测试消息发送
+- 验证同时配置多个服务时的行为
+

+
+### 10.1 飞书与企业微信API对比详情
+
+#### 飞书消息格式
+```json
+{
+  "msg_type": "text",
+  "content": {
+    "text": "Hello <at user_id=\"ou_xxx\">Tom</at>"
+  }
+}
+```
+
+#### 企业微信消息格式
+```json
+{
+  "msgtype": "text",
+  "text": {
+    "content": "Hello World",
+    "mentioned_list": ["wangqing", "@all"],
+    "mentioned_mobile_list": ["13800001111"]
+  }
+}
+```
+
+### 10.2 扩展指南
+
+添加新通知平台步骤：
+
+1. 在 `types.ts` 添加新的 `NotificationProvider` 类型
+2. 在 `providers/` 创建新的服务类，继承 `BaseNotificationService`
+3. 在 `notification-factory.ts` 添加创建逻辑
+4. 在 `config-schema.ts` 添加配置字段
+5. 在 Admin Dashboard 添加UI配置项

+## 0. 设计原则
+
+| 原则 | 说明 |
+|---|---|
+| **UI-Only 配置** | 所有业务配置仅通过 Web 管理后台设置，不再有环境变量覆盖层（仅保留极少数启动参数如 `PORT`、`WEBHOOK_SECRET`、`DATABASE_PATH`） |
+| **4 Provider 并存** | `openai_compatible`（现有兼容格式）、`openai_responses`（Responses API）、`anthropic`（Messages API）、`gemini`（generateContent API） |
+| **SQLite 持久化** | 使用 `bun:sqlite` 零依赖，单文件 `data/assistant.db` |
+| **密钥应用层加密** | API Key 使用 AES-256-GCM 加密后存 DB；主密钥通过环境变量 `ENCRYPTION_KEY` 传入（hex 编码，64 字符 = 32 字节），未设置则拒绝启动 |
+| **不做向前兼容** | 旧 JSON 配置文件方案直接废弃，新版本仅支持数据库配置 |
+

+
+### 4.1 总览对照表
+
+| 特性 | openai_compatible | openai_responses | anthropic | gemini |
+|---|---|---|---|---|
+| **SDK/HTTP** | `openai` npm (`chat.completions`) | `openai` npm (`responses.create`) | `@anthropic-ai/sdk` | `@google/generative-ai` 或 REST |
+| **系统指令** | `messages[0].role='system'` | `instructions` 参数 | `system` 顶层参数 | `systemInstruction` 参数 |
+| **JSON mode** | `response_format: {type:'json_object'}` | `text.format: {type:'json_object'}` | 无原生支持 → prompt 指令 + `JSON.parse` | `responseMimeType: 'application/json'` + `responseSchema` |
+| **工具调用请求** | `tools[].type='function'` + `function.{name,description,parameters}` | `tools[].type='function'` + `function.{name,description,parameters}` | `tools[].name` + `input_schema` | `tools[].functionDeclarations[].{name,description,parameters}` |

+
+### 4.2 各 Adapter 核心转换逻辑
+
+#### 4.2.1 openai_compatible（现有兼容格式）
+
+```typescript
+// 请求转换：几乎直通（这就是现有代码逻辑的抽象）
+// - LLMMessage → OpenAI ChatCompletionMessage (直接映射)
+// - responseFormat='json' → { type: 'json_object' }
+// - tools → tools[].function (直接映射)
+//
+// 响应转换：
+// - choices[0].message.content → content
+// - choices[0].message.tool_calls → toolCalls
+// - choices[0].finish_reason → finishReason (直接映射)
+// - usage.{prompt,completion}_tokens → usage
+```
+
+#### 4.2.2 openai_responses（Responses API）
+
+```typescript
+// 请求转换：
+// - system message 提取为 instructions 参数
+// - 非 system messages 转为 input items
+// - responseFormat='json' → text: { format: { type: 'json_object' } }
+// - tools → tools[].function
+//
+// 响应转换：
+// - output items 中 type='message' → content
+// - output items 中 type='function_call' → toolCalls
+// - status → finishReason 映射
+// - usage.{input,output}_tokens → usage
+```
+
+#### 4.2.3 anthropic（Messages API）
+
+```typescript
+// 请求转换：
+// - system message 提取为 system 顶层参数
+// - 非 system messages → messages（role 直接映射）
+// - responseFormat='json' → 无原生支持，在 system prompt 末尾追加：
+//   "You MUST respond with valid JSON only. No other text."
+// - tools → tools[].{ name, description, input_schema }
+// - tool results → role='user', content: [{ type: 'tool_result', tool_use_id, content }]
+//
+// 响应转换：
+// - content blocks: type='text' → content
+// - content blocks: type='tool_use' → toolCalls (id, name, JSON.stringify(input))
+// - stop_reason: 'end_turn' → 'stop', 'tool_use' → 'tool_calls', 'max_tokens' → 'length'
+// - usage.{input,output}_tokens → usage
+//
+// JSON mode 容错：
+// - JSON.parse(content) 失败时，尝试正则提取 ```json...``` 块
+```
+
+#### 4.2.4 gemini（generateContent API）
+
+```typescript
+// 请求转换：
+// - system message 提取为 systemInstruction: { parts: [{ text }] }
+// - messages → contents[].{ role: 'user'|'model', parts: [{ text }] }
+//   注意：Gemini 用 'model' 而非 'assistant'
+// - responseFormat='json' → generationConfig: {
+//     responseMimeType: 'application/json',
+//     responseSchema: <如果有的话>
+//   }
+// - tools → tools: [{ functionDeclarations: [...] }]
+// - tool results → role: 'function', parts: [{ functionResponse: { name, response } }]
+//
+// 响应转换：
+// - candidates[0].content.parts: type='text' → content
+// - candidates[0].content.parts: functionCall → toolCalls
+// - candidates[0].finishReason: 'STOP' → 'stop', 'FUNCTION_CALL' → 'tool_calls', 'MAX_TOKENS' → 'length'
+// - usageMetadata.{promptTokenCount, candidatesTokenCount} → usage
+```
+
+### 4.3 tool-converter.ts 接口
+
+```typescript
+// ── src/llm/tool-converter.ts ───────────────────────────────
+
+import type { LLMToolDefinition } from './types';
+
+/**
+ * 将内部通用 LLMToolDefinition 转为各 provider 原生格式。
+ * 由各 adapter 在 chat() 中调用。
+ */
+
+/** → OpenAI / OpenAI Compatible 格式 */
+export function toOpenAITools(tools: LLMToolDefinition[]): object[];
+
+/** → Anthropic 格式 */

+
+## 6. 密钥安全设计
+
+### 6.1 Master Key 管理
+
+```
+启动流程:
+  1. 读取环境变量 ENCRYPTION_KEY（hex 编码，64 字符）
+     ├── 未设置或为空 → 抛出错误，拒绝启动
+     ├── 长度不正确   → 抛出错误，提示需要 64 个十六进制字符
+     └── 正确         → 解码为 32 字节 Buffer
+  2. 主密钥常驻内存（进程生命周期）
+  3. 绝对不写入日志、不暴露给 API
+```
+
+### 6.2 加密流程（写 API Key）
+
+```
+输入: plaintext apiKey (string)
+  1. 生成 12 bytes IV: crypto.randomFillSync(new Uint8Array(12))
+  2. 创建 cipher: crypto.createCipheriv('aes-256-gcm', masterKey, iv)
+  3. 加密: ciphertext = Buffer.concat([cipher.update(apiKey, 'utf8'), cipher.final()])
+  4. 获取 auth tag: authTag = cipher.getAuthTag()  // 16 bytes
+  5. 写 DB: INSERT INTO llm_secrets (provider_id, ciphertext, iv, auth_tag, key_version)
+```
+
+### 6.3 解密流程（Gateway 需要调 provider）
+
+```
+输入: provider_id
+  1. 从 DB 读取: { ciphertext, iv, auth_tag, key_version }
+  2. 创建 decipher: crypto.createDecipheriv('aes-256-gcm', masterKey, iv)
+  3. 设置 auth tag: decipher.setAuthTag(authTag)
+  4. 解密: plaintext = Buffer.concat([decipher.update(ciphertext), decipher.final()])
+  5. 返回明文 API Key → 传给 provider factory
+  6. 解密后的 key 随 provider 实例缓存在 Gateway.cache 中
+```
+
+### 6.4 密钥轮换
+
+```
+场景: 管理员更换 ENCRYPTION_KEY
+  1. 启动时读取新的 ENCRYPTION_KEY 环境变量
+  2. 查询所有 llm_secrets WHERE key_version < current_version
+  3. 逐条: 用旧 key 解密 → 用新 key 重加密 → 更新 key_version
+  4. 如果旧 key 不可用（环境变量缺失）→ 启动报错，要求重新设置所有 API Key
+```

+### 7.2 交互规则
+
+| 交互 | 行为 |
+|---|---|
+| **添加 Provider** | 弹出对话框；类型选择后动态显示/隐藏 `base_url` 字段 |
+| **API Key 输入** | 已有 key 时展示 `••••••••`（readonly 占位）；清空内容后保存 = 删除 key；输入新值 = 替换（调用 `PUT /key`）；未修改 = 不发请求 |
+| **测试连接** | 点击后调 `POST /providers/:id/test`；显示 spinner → 成功绿色 toast（延迟+模型）/ 失败红色 toast（错误信息） |
+| **角色分配下拉** | 仅显示 `is_enabled=true` 且 `hasKey=true` 的 provider；选择后自动填充该 provider 的 `default_model`（用户可修改） |
+| **禁用 Provider** | 如果有角色绑定到此 provider → 弹确认对话框："此 Provider 正被以下角色使用：[...]，禁用后这些角色将无法调用 LLM。确定禁用？" |
+| **删除 Provider** | 同上，级联影响提示更强烈 |
+| **模型建议** | 根据 provider type 显示常见模型建议列表（硬编码在前端，仅作参考，不限制输入） |
+
+### 7.3 模型建议列表（前端硬编码参考）
+
+```typescript
+const MODEL_SUGGESTIONS: Record<string, string[]> = {

+## 8. 现有调用点改造清单
+
+### 8.1 后端代码改造
+
+| # | 文件 | 当前代码 | 改造为 | 影响范围 |
+|---|---|---|---|---|
+| 1 | `src/index.ts:69-71` | `const openaiClient = new OpenAI({baseURL, apiKey})` | 删除；初始化 `LLMGateway` 单例并传入业务层 | 入口 |
+| 2 | `src/controllers/review.ts` | 旧版 webhook 存在回退分支 | 删除回退分支，仅保留 `agent` / `codex` 入队逻辑 | 审查主入口 |
+| 3 | `src/review/orchestrator.ts:45,61-63` | `private readonly openai: OpenAI` + `this.openai = new OpenAI(...)` | 构造函数改接收 `LLMGateway`；传给各 agent（任务化分级编排：skip/light/full） | Agent 编排 |
+| 4 | `src/review/agents/specialist-agent.ts:93` | `protected readonly openai: OpenAI` | → `protected readonly gateway: LLMGateway`；`reviewWithOptions()` 与 ReAct 调用改为 `this.gateway.chatForRole('specialist', ...)` | 核心 agent |
+| 5 | `src/review/agents/critic-agent.ts:23` | `private openai: OpenAI` | 同上 | 评审 agent |
+| 6 | `src/review/agents/reflexion-agent.ts:24` | `constructor(openai: OpenAI, ...)` | 构造传 gateway | 反思 agent |
+| 7 | `src/review/agents/debate-orchestrator.ts:17` | `private openai: OpenAI` | 同上 | 辩论 agent |
+| 8 | `src/review/tools/registry.ts:22` | `toOpenAIFunctions()` | → `toToolDefinitions(): LLMToolDefinition[]`（返回内部格式），由 adapter 的 `tool-converter.ts` 负责转换 | 工具注册 |
+| 9 | `src/config/config-schema.ts:120-138` | `OPENAI_BASE_URL/API_KEY/MODEL` 字段定义 | 删除这些字段；`group: 'openai'` → 整个 group 移除 | 配置 schema |
+| 10 | `src/config/config-manager.ts:44-46` | `OPENAI_*` Zod schema 条目 | 删除 | 配置验证 |
+| 11 | `src/config/config-manager.ts:271-273` | `openai: { baseUrl, apiKey, model }` 映射 | 删除整个 `openai` 块 | 配置输出 |
+
+### 8.2 前端代码改造
+
+| # | 文件 | 改造内容 |
+|---|---|---|
+| 1 | `frontend/src/services/configService.ts` | 新增 `llmProviderService.ts`（Provider CRUD + Key 管理 + Role 管理 + Test） |
+| 2 | `frontend/src/components/ConfigManager.tsx` | 添加 "LLM Providers" Tab/Card，引入新组件 |
+| 3 | 新增 | `frontend/src/components/llm/ProviderList.tsx` — Provider 列表表格 |
+| 4 | 新增 | `frontend/src/components/llm/ProviderDialog.tsx` — 添加/编辑对话框 |
+| 5 | 新增 | `frontend/src/components/llm/RoleAssignment.tsx` — 角色分配面板 |
+
+### 8.3 配置层改造
+
+| 变更 | 说明 |
+|---|---|
+| `config-manager.ts` | 精简为只管非 LLM 配置；数据源统一为 `system_settings` 表 |
+| `config-schema.ts` | 移除 `openai` group 及其字段；保留 gitea/feishu/app/admin/review（非模型）字段 |
+| `controllers/config.ts` | LLM 相关接口迁到 `controllers/llm-config.ts`；通用配置接口改读写 DB |
+| `.env.example` | 移除 `OPENAI_*` 和 `REVIEW_MODEL_*`；仅保留启动参数 |
+
+---
+
+## 9. 实施阶段建议
+
+| 阶段 | 内容 | 依赖 | 估时 |
+|---|---|---|---|
+| **Phase 1: 基础设施** | DB 层 (`bun:sqlite` 初始化 + DDL) + crypto 模块 | 无 | 1d |
+| **Phase 2: LLM 抽象层** | `src/llm/` 全部（types + capabilities + errors + gateway + 4 adapters + tool-converter） | Phase 1 | 2d |
+| **Phase 3: 后端 API + 调用点替换** | `controllers/llm-config.ts` + 替换 11 个现有 OpenAI 调用点 + 测试 | Phase 2 | 1.5d |
+| **Phase 4: 前端改造** | Provider 管理 + 角色分配 + 连接测试 UI + 通用设置切 DB | Phase 3 | 1.5d |
+| **Phase 5: 清理与验收** | 删除旧代码 + 更新文档 + E2E 测试 + `.env.example` 精简 | Phase 4 | 0.5d |
+
+**总计约 6.5 人天。**
+
+### 关键里程碑
+
+```
+Day 1:    DB + crypto 就绪，配置写入链路打通
+Day 3:    LLM Gateway 可用，4 个 adapter 通过单元测试
+Day 4.5:  后端 API 完成，所有调用点已替换，`bun test` 全绿
+Day 6:    前端配置页可用，可通过 UI 添加/测试 Provider
+Day 6.5:  旧代码清理完毕，文档更新，Ready for review
+```
+

+
+## 10. 风险与缓解
+
+| 风险 | 影响 | 缓解措施 |
+|---|---|---|
+| **Anthropic 无原生 JSON mode** | `response_format: json_object` 不可用，JSON 解析可能失败 | Adapter 内 prompt 注入 JSON 指令 + `JSON.parse()` 容错（正则提取 \`\`\`json\`\`\` 块 → 重试 parse） |
+| **Gemini function calling 格式差异大** | `functionDeclarations` 包装层级不同；`functionResponse` 嵌套在 `parts` 中 | `tool-converter.ts` 单独处理；finish reason 映射表全覆盖测试 |
+| **Embedding 维度变化导致 Qdrant 不兼容** | `src/review/memory/vector-store.ts` 硬编码 1536 维 | `model_role_assignments.role='embedding'` 变更时，UI 提示用户需重建 collection；或自动检测维度创建新 collection |
+| **ENCRYPTION_KEY 丢失** | 所有加密的 API Key 不可恢复 | 启动时检测密钥版本不匹配 → 报错并要求重新设置所有 API Key（trade-off：安全性 > 便利性） |
+| **SQLite 并发写** | 多请求同时写入可能 SQLITE_BUSY | `bun:sqlite` 开启 WAL mode；写操作走单连接序列化；读可并行 |
+| **Provider SDK 版本冲突** | `openai`、`@anthropic-ai/sdk`、`@google/generative-ai` 三个 SDK 共存 | 各 adapter 独立 import，无交叉依赖；`package.json` 锁定主版本 |
+| **配置热更新** | UI 修改 provider 配置后，正在进行的审查仍用旧配置 | Gateway 缓存按 provider_id 粒度 invalidate；正在执行的请求不受影响（用的是已创建的实例），下次请求用新实例 |
+

+# UI Theme Language（亮/暗双主题统一规范）
+
+## 目标
+
+- 保证浅色/深色主题视觉一致、可读性稳定。
+- 避免组件直接写死颜色，防止后续开发样式漂移。
+- 让新增页面默认遵循同一套语义化设计语言。
+
+## 三层设计语言模型
+
+1. **Primitive（原子值）**：HSL 基础值，仅在全局 token 定义处出现。
+2. **Semantic（语义 token）**：`background`、`foreground`、`success`、`danger` 等，按语义命名。
+3. **Component（组件 token）**：组件只能消费语义 token，不允许跨层引用原子值。
+
+## 当前项目的主题基线
+
+主题定义文件：`frontend/src/index.css`
+
+- 基础语义：`background`、`foreground`、`card`、`muted`、`border`、`ring`
+- 状态语义：`success`、`warning`、`danger`、`info`
+- 补充语义：`surface-muted`、`surface-elevated`、`surface-overlay`、`text-subtle`、`text-soft`、`border-soft`
+
+Tailwind 语义映射：`frontend/tailwind.config.js`
+
+- 已将语义 token 映射为可直接使用的 class（如 `bg-success/10`、`text-danger`、`border-info/20`）。
+
+### 主色方案（当前）
+
+- 主色选择：**Cobalt Blue（钴蓝）**，兼顾 light/dark 的对比度与品牌辨识度。
+- Light：`--primary: 224 76% 52%`，`--primary-foreground: 0 0% 100%`
+- Dark：`--primary: 224 88% 68%`，`--primary-foreground: 224 40% 12%`
+- 焦点环：`--ring` 与 `--primary` 保持同色，确保交互一致性。
+- 设计理由：亮色下避免过“脏”或偏绿感；暗色下提升明度保证可见性，同时用深色前景保证主按钮文字对比。
+
+## 可选整套主题色方案（社区开源复用）
+
+> 要求：切换的是**整套语义 token**，不是只改 `primary`。
+
+当前支持四套（统一冷调科技风）：
+
+1. `cobalt`（默认）
+   - 本项目当前默认冷色科技风（自定义）。
+2. `zinc`
+   - 来源：shadcn/ui themes（MIT）
+   - 参考：<https://github.com/shadcn-ui/ui/blob/main/apps/v4/public/r/themes.css>
+3. `nord`
+   - 来源：Nord（MIT）
+   - 参考：<https://github.com/nordtheme/nord>
+4. `tokyo-night`
+   - 来源：Tokyo Night（Apache-2.0）
+   - 参考：<https://github.com/folke/tokyonight.nvim>
+
+实现方式：
+
+- `cobalt` 作为内置基础主题，直接由 `:root` / `.dark` 提供默认 token。
+- 其余方案（`zinc|nord|tokyo-night`）通过 `data-palette` 覆盖：
+  - `:root[data-palette='*']` 覆盖浅色 token
+  - `.dark[data-palette='*']` 覆盖暗色 token
+- 在根节点写入 `data-palette`（`cobalt|zinc|nord|tokyo-night`）。
+- 组件侧不改业务 class，继续消费语义 token。
+
+## 页面风格骨架（社区方案落地）
+
+> 目标：即使切换配色，页面结构、密度、层级、动效仍保持统一。
+
+本项目采用了三类社区成熟范式，并映射到本仓库 utility：
+
+1. **4px 节奏与密度系统（shadcn/仪表盘实践）**
+   - 基础节奏按 4px 递进，主内容区使用 `theme-page-content`（统一宽度 + 留白节奏）。
+   - 卡片内部与卡片间距默认采用 `p-6 / gap-6` 级别，避免页面“块状松散或拥挤”。
+2. **三层深度系统（卡片/悬浮/遮罩）**
+   - 统一卡片外观：`theme-card-shell` + `theme-card-header` + `theme-card-content`。
+   - 交互抬升统一：`theme-interactive-elevate`（轻微位移 + 阴影，不做夸张动效）。
+   - 页面壳层统一：`theme-shell-gradient` + `theme-sticky-bar`。
+3. **可控动效系统（Linear/Vercel 风格）**
+   - Hover/按钮反馈优先短时平滑动效，避免大幅动画导致“廉价感”。
+   - 表单输入统一 `theme-input-surface`，状态条与统计胶囊统一 `theme-control-pill`。
+
+参考来源：
+
+- shadcn/ui themes 与组件风格实践（MIT）：<https://github.com/shadcn-ui/ui>
+- Vercel Dashboard 设计迭代思路：<https://vercel.com/changelog/dashboard-navigation-redesign-rollout>
+- Nord / Tokyo Night 社区配色体系：
+  - <https://github.com/nordtheme/nord>
+  - <https://github.com/folke/tokyonight.nvim>
+
+## 强制规则（必须遵守）
+
+1. **禁止在业务 TSX 中使用硬编码暗色类**：如 `bg-zinc-*`、`text-zinc-*`、`border-white/10`（历史 UI 基础组件逐步迁移，不作为新增业务代码例外）。
+2. **禁止在组件内写死颜色值**：如 `rgba(...)`、`#xxxxxx`、`rgb(...)`。
+3. **状态色统一语义化**：成功/警告/错误/信息统一用 `success|warning|danger|info`。
+4. **弹窗/卡片/表格优先使用语义表面色**：`card`、`muted`、`popover`、`background`。
+5. **交互阴影统一工具类**：`theme-glow-primary|success|warning|danger`。
+6. **普通 hover 反馈禁止用主色背景**：非主操作控件统一使用 `hover:bg-accent*` 或 `hover:bg-muted*`，避免亮色主题出现重色块。
+
+## 推荐 class 使用方式
+
+- 文字层级：`text-foreground` / `text-muted-foreground`
+- 面板层级：`bg-card` / `bg-muted/50` / `bg-popover`
+- 边框层级：`border-border` / `theme-border-soft`
+- 状态展示：`text-success`、`bg-danger/10`、`border-warning/30`
+- 普通交互 hover：`hover:bg-accent/60`、`hover:bg-accent`、`hover:bg-muted/60`
+- 主操作 hover：仅主按钮可用 `hover:bg-primary/90`
+- 顶部吸附操作栏：`theme-sticky-bar`
+- 页面骨架：`theme-page-frame` / `theme-page-actions` / `theme-page-content`
+- 卡片骨架：`theme-card-shell` / `theme-card-header` / `theme-card-content`
+- 弹窗骨架：`theme-dialog-panel` / `theme-dialog-header` / `theme-dialog-body` / `theme-dialog-footer`
+- 错误态容器：`theme-error-panel`
+- 模态遮罩：`theme-surface-overlay`
+
+## 页面级统一约束（防止布局风格漂移）
+
+1. 页面容器优先使用 `theme-page-frame`，避免每个页面自行定义高度和底部间距。
+2. 顶部操作区统一使用 `theme-sticky-bar + theme-page-actions`，避免按钮栏视觉断层。
+3. 主内容区统一使用 `theme-page-content`，确保横向节奏和留白一致。
+4. 标准业务卡片统一使用 `theme-card-shell/header/content`，避免同类卡片出现不同边框/背景层级。
+5. 错误提示统一使用 `theme-error-panel`，保持状态反馈视觉语言一致。
+
+## destructive 与 danger 的约定
+
+- `destructive`：保留给 shadcn 组件内置 destructive 变体语义。
+- `danger`：业务状态语义（报错、失败、风险提示）统一使用。
+- 新业务组件优先使用 `danger`，避免 `destructive/danger` 混用造成漂移。
+
+## 新功能开发检查清单
+
+- [ ] 页面在 light/dark 下均可读（文本、边框、状态色有对比度）
+- [ ] 无 `zinc/white` 等暗色硬编码 class
+- [ ] 无内联 `style` 颜色值
+- [ ] 状态色全部使用语义 token
+- [ ] 组件未绕过语义层直接访问原子颜色
+- [ ] `bun run ui:visual` 通过（light/dark 关键页面视觉回归）
+
+## 视觉基线截图回归（Playwright）
+
+- 生成/更新基线：`bun run ui:visual:update`
+- 校验基线一致性：`bun run ui:visual`
+- 轻量 UI 全链路：`bun run ui:regression && bun run ui:visual`
+
+约定：
+
+1. PR 默认运行 `ui:visual`，出现 diff 必须人工确认是“预期视觉变更”。
+2. 只有在确认设计变更成立时，才执行 `ui:visual:update` 更新基线并提交快照。
+3. 不允许在未更新设计规范的情况下大量更新视觉基线，避免把漂移“固化为正确”。
+4. 基线快照以 Linux CI 环境为准（当前为 `*-linux.png`），避免跨系统更新导致快照噪声。
+
+## 迁移策略
+
+当新增模块时，按以下顺序处理：
+
+1. 先补充语义 token（如确有新语义，而不是新颜色）。
+2. 在 Tailwind 映射语义 token。
+3. 在组件中只消费语义 class。
+4. 最后做 light/dark 视觉回归。

-The system supports two review engines, selected by `REVIEW_ENGINE` in Admin UI.
+## Overview
+
+The system supports two engines:
+
+- `agent`: native staged review pipeline
+- `codex`: Codex CLI-backed review pipeline
+
+Engine is selected by `REVIEW_ENGINE` runtime configuration.
 
 ## Agent engine
 
-The Agent engine uses a dynamic agent framework. It prepares the workspace and review context, then starts a main agent to perform the review.
-
-### How it works
-
-1. **Main Agent** — the entrypoint agent that coordinates the review. It uses available tools to analyze code changes.
-2. **Dynamic Subagents** — the main agent can autonomously spawn subagents for focused tasks (e.g. searching code, reading files). Subagents are created at runtime through tool calls, not hardcoded in the workflow.
-3. **Deterministic Publishing** — findings and comments are collected and processed outside the agent loop. The system normalizes, deduplicates, and filters findings deterministically before posting to Gitea.
+Agent engine classifies changes and dispatches specialist tasks.
 
 ### Review modes
 
-| Mode | Behavior |
-|---|---|
-| `skip` | Low-risk changes bypass review entirely |
-| `light` | Minimal checks for low-risk code changes |
-| `full` | Complete review for risky or large changes |
+- `skip`: low-risk changes may bypass specialist review
+- `light`: minimal specialist checks for low-risk code changes
+- `full`: full specialist review for risky or larger changes
 
 ### Size policy
 
-Change size determines execution mode and token budgets:
-
-| Size | Typical threshold |
-|---|---|
-| `small` | Few lines changed |
-| `medium` | Moderate change set |
-| `large` | Significant refactoring or many files |
-
-> Size and mode are separate layers: `small/medium/large` classifies how big the change is; `skip/light/full` controls how deeply the engine reviews it.
+`small`/`medium`/`large` thresholds are used by triage to choose mode and token budgets.
 
 ## Codex engine
 
-The Codex engine runs review through Codex CLI with independent runtime settings:
+Codex engine runs review through Codex CLI with independent runtime settings:
 
-| Setting | Description |
-|---|---|
-| `CODEX_API_URL` | Codex API endpoint |
-| `CODEX_API_KEY` | Codex API key |
-| `CODEX_MODEL` | Model to use |
-| `CODEX_TIMEOUT_MS` | Request timeout |
-| `CODEX_REVIEW_PROMPT` | Custom review prompt |
-
-## Agent definitions
-
-Agent definitions are Markdown files with YAML frontmatter stored in the reviewed repository:
-
-```
-.gitea-assistant/agents/*.md
-```
-
-Each file defines:
-
-- **System prompt** — instructions for the agent
-- **Model** — which LLM model to use (optional; falls back to runtime defaults)
-- **Max turns** — limit for the agent loop
-- **Tools** — which tools the agent can access
-
-### Model resolution
-
-When the main agent spawns a subagent, the model is resolved in this order:
-
-1. `spawn` override (explicit in the tool call)
-2. `AgentDefinition.model` (declared in the agent definition file)
-3. `AGENT_DEFAULT_SUBAGENT_MODEL` (runtime config)
-4. `AGENT_MAIN_MODEL` (runtime config)
-
-## Tool permissions
-
-Tool permissions are controlled within each agent's definition file:
-
-| Field | Type | Description |
-|---|---|---|
-| `tools` | Allow list | Tool names the agent is permitted to call. Empty list grants no tools. |
-| `disallowedTools` | Deny list | Tool names the agent is explicitly forbidden from calling. Takes precedence over `tools`. |

 # 审查引擎
 
-系统支持两种审查引擎，通过管理后台的 `REVIEW_ENGINE` 配置选择。
+## 概览
+
+系统支持两种审查引擎：
+
+- `agent`：原生任务化分级审查
+- `codex`：基于 Codex CLI 的审查流水线
+
+通过运行时配置 `REVIEW_ENGINE` 选择引擎。
 
 ## Agent 引擎
 
-Agent 引擎使用动态 Agent 框架执行代码审查。它会准备工作区与审查上下文，然后启动主 Agent 执行审查任务。
-
-### 工作原理
-
-1. **主 Agent** — 协调审查流程的入口 Agent，使用可用工具分析代码变更。
-2. **动态子 Agent** — 主 Agent 可在运行时自主生成子 Agent，执行聚焦任务（如搜索代码、读取文件）。子 Agent 通过工具调用动态创建，而非硬编码在工作流中。
-3. **确定性发布** — 审查发现与评论在 Agent 循环之外收集和处理。系统在发布到 Gitea 之前，对发现进行确定性的规范化、去重和过滤。
+Agent 引擎会先做变更分流，再按领域派发 specialist 任务。
 
 ### 审查模式
 
-| 模式 | 行为 |
-|---|---|
-| `skip` | 低风险改动完全跳过审查 |
-| `light` | 对低风险代码执行最小化检查 |
-| `full` | 对高风险或大规模改动执行完整审查 |
+- `skip`：低风险改动可跳过 specialist
+- `light`：对低风险代码执行最小化专项检查
+- `full`：对高风险或大规模改动执行完整审查
 
 ### 规模策略
 
-变更规模决定执行模式与 Token 预算：
-
-| 规模 | 典型阈值 |
-|---|---|
-| `small` | 少量行变更 |
-| `medium` | 中等变更集 |
-| `large` | 大规模重构或多文件变更 |
-
-> 规模与模式是两个层次：`small/medium/large` 分类变更的大小；`skip/light/full` 控制审查的深度。
+`small` / `medium` / `large` 阈值用于 triage 阶段决策模式与 token 预算。
 
 ## Codex 引擎
 
 Codex 引擎通过 Codex CLI 执行审查，支持独立配置：
 
-| 设置项 | 说明 |
-|---|---|
-| `CODEX_API_URL` | Codex API 端点 |
-| `CODEX_API_KEY` | Codex API 密钥 |
-| `CODEX_MODEL` | 使用的模型 |
-| `CODEX_TIMEOUT_MS` | 请求超时时间 |
-| `CODEX_REVIEW_PROMPT` | 自定义审查提示词 |
-
-## Agent 定义
-
-Agent 定义以带 YAML Frontmatter 的 Markdown 文件形式存储在被审查的仓库中：
-
-```
-.gitea-assistant/agents/*.md
-```
-
-每个文件定义：
-
-- **系统提示词** — Agent 的指令
-- **模型** — 使用的 LLM 模型（可选；未指定时使用运行时默认值）
-- **最大轮数** — Agent 循环上限
-- **工具** — Agent 可使用的工具
-
-### 模型解析
-
-主 Agent 生成子 Agent 时，模型按以下顺序解析：
-
-1. `spawn` 覆盖（工具调用中显式指定）
-2. `AgentDefinition.model`（Agent 定义文件中声明）
-3. `AGENT_DEFAULT_SUBAGENT_MODEL`（运行时配置）
-4. `AGENT_MAIN_MODEL`（运行时配置）
-
-## 工具权限
-
-工具权限在每个 Agent 的定义文件中控制：
-
-| 字段 | 类型 | 说明 |
-|---|---|---|
-| `tools` | 白名单 | 允许该 Agent 调用的工具名称。空列表表示不授予任何工具权限 |
-| `disallowedTools` | 黑名单 | 显式禁止该 Agent 调用的工具名称。优先级高于白名单 |

-# E2E 真实 PR 审查测试指南
-
-本指南记录使用 Docker 运行 Gitea + Assistant 进行真实 PR 代码审查的完整流程，包括踩坑点和修复步骤。
-
-## 前置条件
-
-- Docker & Docker Compose
-- `openssl`（签名计算）
-- `python3`（JSON 解析）
-- 本项目源码
-
-## 架构概览
-
-```
-Gitea (port 3333) ←→ Assistant (port 3334)
-     ↑                    ↑
-  webhook             clone + comment
-  (PR 事件)           (git + API)
-```
-
-- **Gitea**：代码托管，运行在 `gitea:3000`（宿主机 `localhost:3333`）
-- **Assistant**：AI 审查服务，运行在 `assistant:5174`（宿主机 `localhost:3334`）
-- 两者通过 Docker 内部网络 `gitea:3000` 通信（非宿主机地址）
-
-## 一键启动（自动化方式）
-
-```bash
-# 1. 启动容器
-docker compose -f docker-compose.e2e.yml up -d
-
-# 2. 等待 Gitea healthy 后创建用户（Gitea 不允许 root 执行 admin 命令）
-docker exec e2e-gitea su git -c \
-  "gitea admin user create --username e2e-admin --password 'e2ePassword123!' \
-   --email admin@e2e-test.local --admin --must-change-password=false"
-
-# 3. 运行 seed 脚本（创建仓库、推送代码、配置 webhook、创建 PR）
-bash ./e2e/seed.sh
-
-# 4. 用 seed 输出的 token 重启 assistant（使 GITEA_ACCESS_TOKEN 生效）
-#    seed.sh 会在最后打印实际 token 值
-E2E_GITEA_TOKEN=<seed输出的token> docker compose -f docker-compose.e2e.yml up -d assistant
-
-# 5. 通过 Admin API 更新运行时配置
-LOGIN_RESP=$(curl -sf -X POST "http://localhost:3334/admin/api/login" \
-  -H "Content-Type: application/json" -d '{"password": "password"}')
-JWT=$(echo "$LOGIN_RESP" | python3 -c "import sys,json; print(json.load(sys.stdin)['token'])")
-
-curl -sf -X PUT "http://localhost:3334/admin/api/config" \
-  -H "Content-Type: application/json" \
-  -H "Authorization: Bearer $JWT" \
-  -d '{
-    "GITEA_API_URL": "http://gitea:3000/api/v1",
-    "GITEA_ACCESS_TOKEN": "<seed输出的token>",
-    "WEBHOOK_SECRET": "e2e-test-secret"
-  }'
-
-# 6. 运行 E2E 测试
-bash ./e2e/test.sh
-```
-
-## 分步详解与踩坑点
-
-### 1. 启动容器
-
-```bash
-docker compose -f docker-compose.e2e.yml up -d
-```
-
-**踩坑**：`ENCRYPTION_KEY` 和 `WEBHOOK_SECRET` 必须在 `docker-compose.e2e.yml` 中配置，否则 assistant 启动失败（`ENCRYPTION_KEY is required`）。已添加默认值：
-
-```yaml
-assistant:
-  environment:
-    - ENCRYPTION_KEY=${E2E_ENCRYPTION_KEY:-0123456789abcdef...（64位hex）}
-    - WEBHOOK_SECRET=e2e-test-secret
-```
-
-### 2. 创建 Gitea 用户
-
-```bash
-docker exec e2e-gitea su git -c \
-  "gitea admin user create --username e2e-admin --password 'e2ePassword123!' \
-   --email admin@e2e-test.local --admin --must-change-password=false"
-```
-
-**踩坑**：`seed.sh` 中直接 `docker exec e2e-gitea gitea admin user create ...` 会报错 `Gitea is not supposed to be run as root`。必须用 `su git -c` 切换到 git 用户执行。如果用户已存在会输出错误但可忽略。
-
-### 3. Seed 初始化
-
-```bash
-bash ./e2e/seed.sh
-```
-
-Seed 脚本会执行：
-1. 等待 Gitea 就绪
-2. 创建管理员用户（如已存在则跳过）
-3. 生成 API Token
-4. 创建测试仓库并推送含已知 bug 的代码（`src/user-handler.ts` 包含 eval/SQL 注入/硬编码密钥）
-5. 配置 Assistant 设置（需要 assistant 已启动）
-6. 配置 Gitea Webhook（指向 `http://assistant:5174/webhook/gitea`）
-7. 创建 PR #1（`feature/add-user-handler` → `main`）
-
-**踩坑**：seed.sh 第 5 步"配置 Assistant 设置"可能失败（assistant 未启动或 JWT 获取失败），这不影响后续流程——可以手动通过 API 配置。
-
-### 4. 更新 Assistant 运行时配置
-
-```bash
-# 获取 JWT
-JWT=$(curl -sf -X POST "http://localhost:3334/admin/api/login" \
-  -H "Content-Type: application/json" -d '{"password": "password"}' | \
-  python3 -c "import sys,json; print(json.load(sys.stdin)['token'])")
-
-# 更新三个关键配置
-curl -sf -X PUT "http://localhost:3334/admin/api/config" \
-  -H "Content-Type: application/json" \
-  -H "Authorization: Bearer $JWT" \
-  -d '{
-    "GITEA_API_URL": "http://gitea:3000/api/v1",
-    "GITEA_ACCESS_TOKEN": "<token>",
-    "WEBHOOK_SECRET": "e2e-test-secret"
-  }'
-```
-
-**关键**：
-- `GITEA_API_URL` 必须是 `http://gitea:3000/api/v1`（Docker 内部地址），不是 `localhost` 或宿主机地址
-- `GITEA_ACCESS_TOKEN` 是 seed.sh 生成的 token，assistant 用它 clone 仓库和发布评论
-- `WEBHOOK_SECRET` 必须与 Gitea webhook 的 secret 一致，否则签名验证失败
-
-### 5. 触发 PR 审查
-
-PR 创建时 Gitea 会自动触发 webhook。如果需要手动触发：
-
-```bash
-# 获取 PR 信息
-PR_RESP=$(curl -sf "http://localhost:3333/api/v1/repos/e2e-admin/e2e-test-repo/pulls/1" \
-  -H "Authorization: token <token>")
-
-HEAD_SHA=$(echo "$PR_RESP" | python3 -c "import sys,json; print(json.load(sys.stdin)['head']['sha'])")
-BASE_SHA=$(echo "$PR_RESP" | python3 -c "import sys,json; print(json.load(sys.stdin)['base']['sha'])")
-
-# 构造 webhook payload（需包含 head/base SHA）
-cat > /tmp/webhook_payload.json << EOF
-{
-  "action": "opened",
-  "number": 1,
-  "pull_request": {
-    "number": 1,
-    "title": "feat: add user handler",
-    "head": { "ref": "feature/add-user-handler", "sha": "$HEAD_SHA",
-              "repo": { "clone_url": "http://gitea:3000/e2e-admin/e2e-test-repo.git" } },
-    "base": { "ref": "main", "sha": "$BASE_SHA",
-              "repo": { "clone_url": "http://gitea:3000/e2e-admin/e2e-test-repo.git" } }
-  },
-  "repository": {
-    "full_name": "e2e-admin/e2e-test-repo",
-    "name": "e2e-test-repo",
-    "owner": { "login": "e2e-admin" },
-    "clone_url": "http://gitea:3000/e2e-admin/e2e-test-repo.git"
-  },
-  "sender": { "login": "e2e-admin" }
-}
-EOF
-
-# 计算 HMAC 签名（注意：必须基于文件内容计算，避免 shell 变量传递时改变内容）
-SIG=$(cat /tmp/webhook_payload.json | openssl dgst -sha256 -hmac "e2e-test-secret" | awk '{print $NF}')
-
-# 发送 webhook（⚠️ 必须用 --data-binary 而非 -d，否则换行符被剥离导致签名不匹配）
-curl -s -X POST "http://localhost:3334/webhook/gitea" \
-  -H "Content-Type: application/json" \
-  -H "X-Gitea-Event: pull_request" \
-  -H "X-Gitea-Signature: ${SIG}" \
-  --data-binary @/tmp/webhook_payload.json
-```
-
-### 6. 验证审查结果
-
-```bash
-# 等待审查完成
-sleep 10
-
-# 检查 assistant 日志
-docker logs e2e-assistant 2>&1 | grep -E "审查|publish|评论|finding|ERROR" | tail -20
-
-# 通过 API 查看 run 详情
-curl -sf "http://localhost:3334/admin/api/review/runs" \
-  -H "Authorization: Bearer $JWT" | python3 -m json.tool | head -30
-
-# 检查 Gitea PR 评论（summary）
-curl -sf "http://localhost:3333/api/v1/repos/e2e-admin/e2e-test-repo/issues/1/comments" \
-  -H "Authorization: token <token>" | python3 -c "
-import sys,json
-for c in json.load(sys.stdin):
-    print(c['body'][:200])
-"
-
-# 检查 Gitea PR Reviews（行级评论）
-curl -sf "http://localhost:3333/api/v1/repos/e2e-admin/e2e-test-repo/pulls/1/reviews" \
-  -H "Authorization: token <token>"
-```
-
-## 验证检查清单
-
-| # | 检查项 | 验证方式 |
-|---|--------|----------|
-| 1 | Gitea 容器 healthy | `docker ps` 或 `curl localhost:3333/api/v1/version` |
-| 2 | Assistant 容器 healthy | `curl localhost:3334/api/health` |
-| 3 | Webhook 签名验证通过 | assistant 日志无"签名验证失败" |
-| 4 | Git clone mirror 成功 | assistant 日志无"could not read Username" |
-| 5 | Agent 审查执行完成 | run status = `succeeded` |
-| 6 | Subagent 被触发 | sessionTree.invocations 非空 |
-| 7 | Findings 数量 > 0 | run details 中 findings 非空 |
-| 8 | Summary 评论发布到 Gitea | PR issue comments 包含"AI Agent代码审查结果" |
-| 9 | 行级评论发布到 Gitea | PR reviews 包含 COMMENT 类型 |
-| 10 | Finding published=true | DB 中 finding.published = true |
-
-## Mock LLM vs 真实 LLM
-
-| 特性 | E2E_MOCK_LLM=1 | 真实 LLM |
-|------|----------------|----------|
-| 模型 | `RuntimeE2EMockLLM`（脚本驱动） | OpenAI/Anthropic/其他 |
-| Subagent | 必然调用（固定脚本） | 动态决策（根据 diff 复杂度） |
-| Findings | 固定 1 条（eval 安全问题） | 根据实际代码动态发现 |
-| 速度 | <1s | 10-60s |
-| 用途 | 集成链路验证 | 审查质量验证 |
-
-## 常见问题
-
-### `ENCRYPTION_KEY is required`
-**原因**：`docker-compose.e2e.yml` 缺少 `ENCRYPTION_KEY` 环境变量。
-**修复**：已在 compose 文件中添加默认值。
-
-### `Webhook签名验证失败`
-**原因**：请求的 HMAC 签名与 assistant 配置的 `WEBHOOK_SECRET` 不匹配。
-**修复**：确保 webhook payload 的签名计算使用与 Admin API 配置的 `WEBHOOK_SECRET` 相同的密钥。
-
-### `could not read Username for 'http://gitea:3000'`
-**原因**：`GITEA_ACCESS_TOKEN` 未正确配置（默认值 `placeholder`）或 DB 配置中的值不正确。
-**修复**：通过 Admin API 更新 `GITEA_ACCESS_TOKEN` 为 seed.sh 生成的实际 token。
-
-### `Gitea is not supposed to be run as root`
-**原因**：Gitea 容器以 root 运行，但 `gitea admin` 命令不允许 root 执行。
-**修复**：使用 `docker exec e2e-gitea su git -c "gitea admin user create ..."` 格式。
-
-### Gitea API URL 指向 localhost
-**原因**：assistant DB 中 `GITEA_API_URL` 默认值为 `http://localhost:5174/api/v1`（自身地址）。
-**修复**：通过 Admin API 更新为 `http://gitea:3000/api/v1`（Docker 内部地址）。
-
-### 评论未发布到 Gitea
-**原因**：Agent 引擎的 `publishPendingComments` 链路缺失（已修复）。
-**修复**：确保使用包含 `publishPendingComments` 逻辑的版本。
-
-## 清理
-
-```bash
-docker compose -f docker-compose.e2e.yml down -v
-```
-
-`-v` 会删除 Gitea 数据卷，下次启动需要重新 seed。
