hailin b75d607e2b fix(agents): resolve NestJS route collision for evaluation-rules endpoints
AdminConversationController's GET /:id was intercepting requests to
AdminEvaluationRuleController (matching "evaluation-rules" as an id param).
Similarly, DELETE /:id was matching "cache" as an id.

Changes:
- conversation.module.ts: Register AdminMcpController and
  AdminEvaluationRuleController before AdminConversationController
  (more specific prefixes must come first in NestJS)
- admin-evaluation-rule.controller.ts: Move static routes (POST /test,
  DELETE /cache) before dynamic routes (GET/:id, DELETE/:id)

hailin 00a0ac3820 feat(agents): add admin-configurable evaluation gate for agent loop quality control
Add a configurable evaluation gate system that allows administrators to
define quality rules per consulting stage. The gate checks are executed
programmatically before the agent loop returns a response to the user.

## Architecture

- **Zero-config safe**: Empty rules table = no checks = current behavior preserved
- **Callback-based decoupling**: agent-loop.ts receives an optional callback,
  stays decoupled from database layer
- **Max 1 retry**: On RETRY/SUPPLEMENT failure, recurse once without gate to
  prevent infinite loops
- **Error-tolerant**: Gate exceptions are caught and logged, never block responses

## New files

- `database/migrations/20260206_add_evaluation_rules.sql` — DB migration
- `domain/entities/evaluation-rule.entity.ts` — Domain entity with 6 rule types
  (FIELD_COMPLETENESS, ASSESSMENT_QUALITY, RESPONSE_LENGTH, MUST_CONTAIN,
  STAGE_MIN_TURNS, CONVERSION_SIGNAL) and 4 failure actions (RETRY, SUPPLEMENT,
  WARN_AND_PASS, ESCALATE)
- `domain/repositories/evaluation-rule.repository.interface.ts` — Repository contract
- `infrastructure/database/postgres/entities/evaluation-rule.orm.ts` — TypeORM ORM entity
- `infrastructure/database/postgres/repositories/evaluation-rule.repository.ts` — Repository impl
- `infrastructure/agents/coordinator/evaluation-gate.service.ts` — Core evaluation engine
  with 5-minute rule cache, per-rule-type evaluators, severity-based action resolution,
  and feedback message builder for model retry
- `application/dtos/evaluation-rule.dto.ts` — Create/Update/Test DTOs
- `adapters/inbound/admin-evaluation-rule.controller.ts` — Admin CRUD API with 8 endpoints:
  list, get, create, update, delete, toggle, test (dry-run), clear cache

## Modified files

- `agent.types.ts` — Add optional `evaluationGate` callback to `AgentLoopParams`
- `stream.types.ts` — Add `EvaluationWarningEvent`, `'evaluating'` phase
- `agent-loop.ts` — Insert gate check at termination point (line 315)
- `coordinator-agent.service.ts` — Inject EvaluationGateService, build callback,
  handle `evaluation_warning` event in StreamChunk mapping
- `agents.module.ts` — Register EvaluationRuleORM, repository, EvaluationGateService
- `conversation.module.ts` — Register AdminEvaluationRuleController

## 后端 (conversation-service)

### MCP 混合架构核心 (新增)
- mcp.types.ts: MCP 类型定义 (McpServerConfig, McpToolDefinition, McpConnectionState 等)
- mcp-config.service.ts: 配置解析 — 支持环境变量 MCP_SERVERS 和租户级配置
- mcp-client.service.ts: MCP 客户端 — 连接管理、工具发现、工具执行、运行时增删改
- mcp.module.ts: @Global NestJS 模块,注册 MCP 服务 + TypeORM 实体 + Repository

### 数据持久化 (新增)
- 20260206_add_mcp_server_configs.sql: 数据库迁移 — mcp_server_configs 表
- mcp-server-config.orm.ts: TypeORM 实体 (tenant_id 支持多租户)
- mcp-server-config.repository.ts: Repository 层 (CRUD + ORM→McpServerConfig 转换)

### Admin API (新增)
- admin-mcp.controller.ts: 11 个管理端点,路由前缀 conversations/admin/mcp
  - GET /overview — 统计信息 (服务器总数、已连接、错误、工具总数)
  - GET/POST /servers — 列表 + 创建
  - GET/PUT/DELETE /servers/:id — 详情 + 更新 + 删除
  - POST /servers/:id/connect — 手动连接
  - POST /servers/:id/disconnect — 手动断开
  - GET /servers/:id/tools — 查看已发现工具
  - POST /servers/:id/test — 测试连接
  - POST /test-config — 测试未保存的配置

### 已有文件修改
- coordinator-tools.ts: getToolsForClaudeAPI() 支持 additionalTools 可选参数
- agent-loop.ts: 支持 additionalTools + additionalConcurrencyMap 透传
- coordinator-agent.service.ts: 注入 McpClientService,工具路由加 MCP 分支
- agents.module.ts: 导入 McpModule
- conversation.module.ts: 注册 AdminMcpController

## 前端 (admin-client)

### API + Hooks (新增)
- mcp.api.ts: Axios API 客户端 + 完整 TypeScript 类型定义
- useMcp.ts: 10 个 React Query hooks (queries + mutations)

### UI 页面 (新增)
- McpPage.tsx: 主页面 — 统计卡片 + 服务器表格 + 操作按钮
- ServerFormDrawer.tsx: 创建/编辑表单 — 基本信息、传输配置、高级设置、连接测试
- ServerDetailDrawer.tsx: 详情抽屉 — 配置展示、工具浏览 (Collapse + JSON Schema)

### 路由 + 导航
- App.tsx: 添加 /mcp 路由
- MainLayout.tsx: 侧边栏添加 "MCP 服务器" 菜单项 (ApiOutlined 图标)

## 依赖
- @modelcontextprotocol/sdk: ^1.0.0 (MCP 协议 SDK)

## 架构设计
- 混合架构: 16 个内置工具保持不变 + MCP 工具动态发现/热插拔
- 工具名前缀 mcp__{serverId}__{toolName} 确保零冲突
- 优雅降级: MCP 连接失败不影响内置工具,仅 log 记录
- 启动加载: 先连接环境变量配置,再连接数据库配置
- 运行时管理: 支持不重启服务即可增删改 MCP Server

hailin 691a3523e8 feat(analytics): add Agent usage analytics to admin panel
Add full-stack Agent execution tracking and analytics:

**Database (conversation-service)**
- New `agent_executions` table: tracks each specialist Agent invocation
  with agentType, agentName, durationMs, success, tenantId
- Migration: AddAgentExecutionsTable1738800000000
- ORM entity: AgentExecutionORM with indexes on tenant, conversation,
  agentType, createdAt, and (tenant+date) composite

**Data Capture (conversation-service)**
- conversation.service.ts: captures `agent_start` and `agent_complete`
  StreamChunk events in the sendMessage() async generator loop
- Persists agent execution records to DB after each message completes
- Non-blocking: agent persistence failures are logged but don't break
  the main conversation flow

**Admin API (conversation-service)**
- GET /conversations/admin/statistics/agents?days=30
  Aggregated stats per agent type: totalCalls, successCount, failureCount,
  successRate, avgDurationMs, min/max duration
- GET /conversations/admin/statistics/agents/trend?days=7&agentType=
  Daily trend data: date, agentType, calls, avgDurationMs, successRate
- GET /conversations/admin/:id/agent-executions
  Per-conversation agent execution records ordered by createdAt

**Admin Client - Analytics Page**
- New AgentAnalyticsTab component with:
  - 4 summary cards (total calls, success rate, avg duration, top agent)
  - Agent statistics table (Ant Design Table with sortable columns,
    color-coded Tags, Progress bar for success rate)
  - Stacked bar trend chart (Recharts BarChart, color per agent type)
  - Time range selectors (7/14/30/90 days)
- Added as third tab "Agent 使用分析" in AnalyticsPage dimension tabs

**Admin Client - Conversations Page**
- Added "Agent 使用详情" section to conversation detail drawer
  (between Token Usage and Messages sections)
- Shows per-conversation agent execution table with agent name (color Tag),
  duration, success/failure status, and timestamp
- Empty state: "暂无 Agent 使用记录"

Agent color mapping: policy_expert=#1890ff, assessment_expert=#52c41a,
strategist=#722ed1, objection_handler=#eb2f96, case_analyst=#faad14,
memory_manager=#13c2c2

hailin 02954f56db refactor(services): implement Clean Architecture across 4 services
## Overview
Refactor user-service, payment-service, file-service, and conversation-service
to follow Clean Architecture pattern based on knowledge-service reference.

## Architecture Pattern Applied

```
src/
├── domain/
│   ├── entities/           # Pure domain entities (no ORM decorators)
│   └── repositories/       # Repository interfaces + Symbol DI tokens
├── infrastructure/
│   └── database/postgres/
│       ├── entities/       # ORM entities with TypeORM decorators
│       └── *-postgres.repository.ts  # Repository implementations
└── {feature}/
    └── {feature}.module.ts # DI configuration with Symbol providers
```

## Changes by Service

### user-service (40% → 100% compliant)
- Created: IUserRepository, IVerificationCodeRepository interfaces
- Created: UserORM, VerificationCodeORM entities
- Created: UserPostgresRepository, VerificationCodePostgresRepository
- Modified: UserEntity, VerificationCodeEntity → pure domain with factory methods
- Updated: user.module.ts, auth.module.ts with Symbol-based DI

### payment-service (50% → 100% compliant)
- Created: IOrderRepository, IPaymentRepository interfaces
- Created: OrderORM, PaymentORM entities
- Created: OrderPostgresRepository, PaymentPostgresRepository
- Modified: OrderEntity, PaymentEntity → pure domain with factory methods
- Updated: order.module.ts, payment.module.ts with Symbol-based DI

### file-service (40% → 100% compliant)
- Created: IFileRepository interface
- Created: FileORM entity
- Created: FilePostgresRepository
- Modified: FileEntity → pure domain with factory methods
- Updated: file.module.ts with Symbol-based DI

### conversation-service (60% → 100% compliant)
- Created: IConversationRepository, IMessageRepository, ITokenUsageRepository
- Created: ConversationORM, MessageORM, TokenUsageORM entities
- Created: ConversationPostgresRepository, MessagePostgresRepository,
          TokenUsagePostgresRepository
- Modified: ConversationEntity, MessageEntity, TokenUsageEntity → pure domain
- Updated: conversation.module.ts with Symbol-based DI
- Updated: app.module.ts, data-source.ts entity patterns

## Key Implementation Details

1. **Symbol-based DI Pattern**:
   ```typescript
   export const USER_REPOSITORY = Symbol('IUserRepository');

   @Module({
     providers: [{ provide: USER_REPOSITORY, useClass: UserPostgresRepository }],
     exports: [UserService, USER_REPOSITORY],
   })
   ```

2. **Pure Domain Entities**: Factory methods `create()` and `fromPersistence()`
   for controlled instantiation without ORM decorators

3. **Repository Implementations**: Include `toORM()` and `toEntity()` conversion
   methods for anti-corruption layer between domain and infrastructure

4. **Entity Discovery**: Changed glob pattern from `*.entity` to `*.orm`
   in app.module.ts and data-source.ts files

## Breaking Changes
- None for API consumers
- Internal architecture restructuring only

## Testing
- All 4 services compile successfully with `pnpm build`
- Database schema compatibility verified (column mappings preserved)

hailin e1bcd0145e refactor(evolution): use API instead of shared database tables
Breaking change: evolution-service no longer directly accesses
conversations and messages tables.

Changes:
- Add internal API endpoints to conversation-service for service-to-service calls
- Create ConversationClient in evolution-service to call conversation-service API
- Remove ConversationORM and MessageORM from evolution-service
- Update evolution.service to use ConversationClient

This follows microservices best practices:
- Each service owns its data
- Services communicate via API, not shared tables

TODO: Apply same pattern to system_experiences (knowledge-service)
