hailin 73dee93d19 feat(docling): persist model cache via Docker volume
- Add docling_models volume mounted at /models in container
- Set HF_HOME=/models/huggingface at runtime (via docker-compose env)
- Models download once → persist in volume → survive container rebuilds
- Build-time preload uses || to not block build if network unavailable

hailin 764613bd86 fix(docling): use standalone script for model pre-download
Inline Python one-liner had syntax errors (try/except/finally can't be
single-line). Move to scripts/preload_models.py for reliable execution.

hailin d725864cd6 fix(docling): pre-download models during Docker build
DocumentConverter() constructor only sets up config, models are lazily
downloaded on first convert(). Fix by running an actual PDF conversion
during build to trigger HuggingFace model download and cache.

hailin 57d21526a5 feat(knowledge): add Docling document parsing microservice
Add IBM Docling as a Python FastAPI microservice for high-quality document
parsing with table structure recognition (TableFormer ~94% accuracy) and
OCR support, replacing pdf-parse/mammoth as the primary text extractor.

Architecture:
- New docling-service (Python FastAPI, port 3007) in Docker network
- knowledge-service calls docling-service via HTTP POST multipart/form-data
- Graceful fallback: if Docling fails, falls back to pdf-parse/mammoth
- Text/Markdown files skip Docling (no benefit for plain text)

Changes:
- New: packages/services/docling-service/ (main.py, Dockerfile, requirements.txt)
- docker-compose.yml: add docling-service, wire DOCLING_SERVICE_URL to
  knowledge-service, add missing FILE_SERVICE_URL to conversation-service
- text-extraction.service.ts: inject ConfigService, add extractViaDocling()
  with automatic fallback to legacy extractors
- .env.example: add FILE_SERVICE_PORT/URL and DOCLING_SERVICE_PORT/URL

Inter-service communication map:
  conversation-service → file-service (FILE_SERVICE_URL, attachments)
  conversation-service → knowledge-service (KNOWLEDGE_SERVICE_URL, RAG)
  knowledge-service → docling-service (DOCLING_SERVICE_URL, document parsing)

hailin 5338bdfc0f fix(agents): correct Claude API file size limits (image 5MB, PDF 25MB)
Claude API enforces a hard 5MB limit per image (not 20MB as previously
set). PDFs have a 32MB total request limit; set individual PDF cap to
25MB to leave room for prompt/messages. The downloadAsBase64 method now
accepts a per-type maxSize parameter.

hailin e867ba5529 fix(files): replace MinIO presigned URLs with API proxy + base64 for Claude
MinIO presigned URLs use Docker-internal hostname (minio:9000), making
them inaccessible from both Claude API servers and user browsers.

Changes:
- file-service: add /files/:id/content and /files/:id/thumbnail proxy
  endpoints that stream file data from MinIO
- file-service: toResponseDto now returns API proxy paths instead of
  MinIO presigned URLs
- coordinator: buildAttachmentBlocks now downloads files via file-service
  internal API (http://file-service:3006) and converts to base64 for
  Claude API (images, PDFs) or embeds text content directly
- Configurable FILE_SERVICE_URL env var for service-to-service calls

hailin 8f7b633041 fix(agents): download text file content for Claude instead of passing URL
Claude API cannot fetch arbitrary URLs. Text-based attachments (txt, csv,
json, md) are now downloaded via their presigned MinIO URL and embedded
directly as text blocks. PDF uses Claude's native document block. Added
50KB size limit with truncation for large text files.

buildMessages() is now async to support text content fetching.

hailin 5076e16cc7 feat: add document support for Claude + image thumbnail generation
1. Coordinator now sends all attachment types to Claude:
   - Images → native image blocks (existing)
   - PDF → native document blocks (Claude PDF support)
   - Text files (txt, csv, json, md) → text blocks with filename
   Extracted common buildAttachmentBlocks() helper.

2. File-service generates thumbnails on image upload:
   - Uses sharp to resize to 400x400 max (inside fit, no upscale)
   - Output as WebP at 80% quality for smaller file size
   - Stored in MinIO under thumbnails/ prefix
   - Generated for both direct upload and presigned URL confirm
   - Non-blocking: thumbnail failure doesn't break upload

hailin 6592e72758 fix(agents): filter out internal strategy notes from followUp output
The model was putting internal notes like "引导回移民话题" in the followUp

1. Schema: describe followUp as "必须以?结尾,禁止填写内部策略备注"
2. agent-loop: only yield followUp if it contains ?or ? (question mark)

hailin 9e9865acb0 fix(tools): 修复 coordinator-tools 与 immigration-tools 之间的 input_schema 不一致
## 问题

全链路检查发现 coordinator-tools.ts(Claude 实际使用的工具定义)与
immigration-tools.service.ts(实际执行器)之间有 4 处 input_schema 不一致,
会导致 Claude 发送的参数无法被正确解析。

## 修复

### check_off_topic
- coordinator 发 `query`,handler 读 `question`
- Fix: handler 同时支持 `query` 和 `question` 两个字段名

### collect_assessment_info
- coordinator 发 `{ userId, field, value }`(单字段模式)
- handler 读 `{ category, age, education, ... }`(批量模式)
- Fix: handler 同时支持两种输入格式

### generate_payment
- coordinator 旧 schema: `{ userId, serviceType, amount, description }`
- handler 需要: `{ serviceType, category, paymentMethod }`
- Fix: 更新 coordinator schema 为 `{ serviceType, category, paymentMethod }`
  - serviceType enum 改为 ASSESSMENT/CONSULTATION/DOCUMENT_REVIEW(匹配 payment-service)
  - 添加 category enum 和 paymentMethod enum
  - 移除 userId(从 context 获取)和 amount(由 payment-service 定价)

### save_user_memory
- coordinator 旧 schema 多余 `userId`(handler 用 context.userId)
- coordinator 发 `importance` 但 handler 不读
- handler 支持 `category` 但 coordinator 未定义
- Fix: coordinator schema 移除 userId,移除 importance,添加 category

hailin a3f2be078b feat(payment): P2 — 订单管理增强,支持取消订单和订单详情查询
## 后端改动

### PaymentClientService 增强
- 新增 `getOrderDetail(orderId)` — 获取完整订单信息(含支付详情)
- 新增 `cancelOrder(orderId)` — 取消未支付订单(调用 POST /orders/:id/cancel)

### 新增 cancel_order 工具
- 工具定义: 接收 orderId,取消未支付订单
- 实现: 调用 PaymentClientService.cancelOrder()
- 成功返回 { success, orderId, status, message }
- 失败返回友好错误信息(如"只有未支付的订单才能取消")
- coordinator-tools.ts 注册,concurrency map 标记 false(写操作)

## 前端改动

### cancel_order 结果渲染
- 成功: 绿色卡片 + CheckCircle 图标 + 成功提示
- 失败: 红色卡片 + AlertCircle 图标 + 错误原因
- 显示订单号

## 注意事项
- payment-service 暂无退款 API,cancel_order 仅限未支付订单
- 退款功能待 payment-service 侧实现后再扩展

hailin bb1a1139a3 feat(agents): add 4-layer response quality control — structured outputs, LLM judge, smart truncation
AI回复质量硬约束系统,解决核心问题:AI无法用最少的语言精准回答用户问题。

## 四层防线架构

### Layer 1 — Prompt 优化 (软约束)
- coordinator-system-prompt.ts: 新增"最高优先级原则:精准回答"章节
  - 意图分类表(7种)+ 每种对应长度和回答策略
  - 错误示范 vs 正确示范对比
  - "宁可太短,不可太长"原则
  - 最终提醒三条:精准回答 > 准确性 > 简洁就是专业
- policy-expert-prompt.ts: 精简输出格式
- objection-handler-prompt.ts: 微调

### Layer 2 — Structured Outputs (格式约束)
- 新文件 coordinator-response.schema.ts: Zod schema 定义
  - intent: 7种意图分类 (factual/yes_no/comparison/assessment/objection/detailed/casual)
  - answer: 回复文本
  - followUp: 可选跟进问题
- agent-loop.ts: 通过 output_config 传入 Claude API,强制 JSON 输出
  - 流式模式下抑制 text delta(JSON 片段不展示给用户)
  - 流结束后解析 JSON,提取 answer 字段 yield 给前端
  - JSON 解析失败时回退到原始文本(安全降级)
- coordinator-agent.service.ts: 传入 zodOutputFormat(CoordinatorResponseSchema)
- agent.types.ts: AgentLoopParams 新增 outputConfig 字段

### Layer 3 — LLM-as-Judge (语义质检)
- evaluation-rule.entity.ts: 新增 LLM_JUDGE 规则类型(第9种)
- evaluation-gate.service.ts:
  - 注入 ConfigService + 初始化 Anthropic client (Haiku 4.5)
  - evaluateRule 改为 async(支持异步 LLM 调用)
  - 新增 checkLlmJudge():评估 relevance/conciseness/noise 三维度
  - 可配置阈值:minRelevance(7), minConciseness(6), maxNoise(3)
  - 5s 超时 + 异常默认通过(非阻塞)
  - EvaluationContext 新增 userMessage 字段
- coordinator-agent.service.ts: 传入 userMessage 到评估门控

### Layer 4 — 程序级硬截断 (物理约束)
- coordinator-response.schema.ts:
  - INTENT_MAX_ANSWER_LENGTH: 按意图限制字符数
    factual=200, yes_no=120, comparison=250, assessment=400,
    objection=200, detailed=500, casual=80
  - MAX_FOLLOWUP_LENGTH: 80 字符
  - smartTruncate(): 在句子边界处智能截断(中英文标点)
- agent-loop.ts: JSON 解析后按 intent 强制截断 answer 和 followUp
- max_tokens 从 4096 降至 2048

## Bug 修复
- agent-loop.ts: currentTextContent 在 content_block_stop 时被重置为空字符串,
  导致评估门控收到空文本。改为从 finalMessage.content 提取 responseText。

## 依赖升级
- @anthropic-ai/sdk: 0.52.0 → 0.73.0 (支持 output_config)
- 新增 zod@4.3.6 (Structured Output schema 定义)

## 文件清单 (1 new + 10 modified)
- NEW: agents/schemas/coordinator-response.schema.ts
- MOD: agents/coordinator/agent-loop.ts (核心改造)

hailin 04dbc61131 feat(agents): add capability boundary guardrails — input gate, cascading fallback, output gate rules
Four guardrail improvements to enforce agent capability boundaries:

1. Cascading Fallback (Fix 1+4):
   - Rewrite searchKnowledge() in immigration-tools.service.ts with 3-tier fallback:
     KB (similarity >= 0.55) → Web Search → Built-in Knowledge (clearly labeled)
   - Rewrite executeTool() in policy-expert.service.ts to use retrieveKnowledge()
     with confidence threshold; returns [KB_EMPTY]/[KB_LOW_CONFIDENCE]/[KB_ERROR]
     markers so the model knows to label source reliability

2. Input Gate (Fix 2):
   - New InputGateService using Haiku for lightweight pre-classification
   - Classifications: ON_TOPIC / OFF_TOPIC (threshold >= 0.7) / HARMFUL (>= 0.6)
   - Short messages (< 5 chars) fast-path to ON_TOPIC
   - Gate failure is non-fatal (allows message through)
   - Integrated in CoordinatorAgentService.sendMessage() before agent loop entry
   - OFF_TOPIC/HARMFUL messages get fixed responses without entering agent loop

3. Output Gate Enhancement (Fix 3):
   - Add TOPIC_BOUNDARY and NO_FABRICATION to EvaluationRuleType
   - TOPIC_BOUNDARY: regex detection for code blocks, programming keywords,
     AI identity exposure, off-topic indicators in agent responses
   - NO_FABRICATION: detects policy claims without policy_expert invocation
     or source markers; ensures factual claims are knowledge-backed
   - Both rule types are admin-configurable (zero rules = zero checks)
   - No DB migration needed (ruleType is varchar(50))

Files changed:
- NEW: agents/coordinator/input-gate.service.ts
- MOD: agents/coordinator/coordinator-agent.service.ts (inject InputGate + gate check)
- MOD: agents/agents.module.ts (register InputGateService)
- MOD: agents/coordinator/evaluation-gate.service.ts (2 new evaluators)
- MOD: domain/entities/evaluation-rule.entity.ts (2 new rule types)
- MOD: agents/specialists/policy-expert.service.ts (RAG confidence threshold)
- MOD: claude/tools/immigration-tools.service.ts (cascading fallback)

hailin d81f03d318 feat(agents): persist evaluation gate failures as system experiences for cross-conversation learning
将评估门控的失败教训自动沉淀为全局系统经验,实现跨对话学习闭环:

1. KnowledgeClientService 新增 saveExperience() 方法
   - 封装 knowledge-service 的 POST /memory/experience API
   - 支持保存 experienceType、scenario、content、confidence 等字段
   - 错误处理:失败时返回 null,不影响主流程

2. CoordinatorAgentService 评估门控回调扩展
   - Gate 失败(RETRY/SUPPLEMENT)时,异步将失败教训写入 knowledge-service
   - fire-and-forget 模式:不阻塞重试流程,失败仅打印警告
   - 经验格式:scenario = "阶段 + 规则名",content = "具体要求描述"
   - experienceType = KNOWLEDGE_GAP,confidence = 45(低于默认50,需积累)

3. 学习闭环机制
   - 经验写入后状态为 PENDING,需 admin 审核激活(isActive=true)
   - 激活后 Context Injector 的 searchExperiences() 语义匹配检索
   - 未来对话中注入 prompt → AI 第一次就遵循规则,避免重复犯错
   - knowledge-service 自动去重:0.9 相似度阈值合并,confidence +5/次

4. 零侵入保证
   - 无评估规则时 Gate 直接 PASS → 不保存任何经验 → 原有流程零影响
   - agent-loop.ts 未修改,所有逻辑在 coordinator 回调闭包内完成

The delete conversation endpoint was a no-op — it verified ownership but
never actually modified the record. Users saw conversations disappear
(frontend optimistic removal) but they reappeared on refresh.

Changes:
- conversation.entity.ts: Add DELETED status, softDelete() and isDeleted()
- conversation.service.ts: Call softDelete() + update instead of no-op
- conversation-postgres.repository.ts: Exclude DELETED conversations
  from findByUserId() queries so they don't appear in user's list

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

hailin 714a674818 feat(mcp): add MCP Server management — backend API + admin UI
实现完整的 MCP (Model Context Protocol) 服务器管理功能,包括后端 API 和管理界面。

## 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)

hailin fb811c7cf4 fix(agents): prevent usage events from emitting stream_end to frontend
The mapEventToStreamChunk was mapping both 'usage' (per-turn) and 'end'
(final) events to type 'end', causing the gateway to emit multiple
stream_end events. This made the frontend create a separate message
bubble (with its own bot avatar) for each agent loop turn.

- 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 16cc0e4c08 feat(agents): implement multi-agent collaboration architecture
借鉴 Claude Code 的架构模式,将单一 Agent 重构为 Coordinator + 6 Specialist 多 Agent 协作系统。

## 新增文件 (36个)

### 架构设计文档 (docs/architecture/, 12个)
- 00-overview.md ~ 11-prompt-templates.md: 完整架构设计,覆盖所有 Agent 的详细设计、
  Prompt 模板、协作流程、工具并发系统、动态上下文注入

### 多 Agent 系统 (infrastructure/agents/, 23个)
- coordinator/coordinator-agent.service.ts: 主协调器,替代 ClaudeAgentServiceV2
- coordinator/agent-loop.ts: 核心递归 async generator 循环(参考 Claude Code aM())
- coordinator/context-injector.service.ts: 动态上下文注入(8种上下文类型按优先级注入)
- specialists/base-specialist.service.ts: Agent 基类(封装 Claude API 调用 + prompt 缓存)
- specialists/policy-expert.service.ts: 政策专家 (Sonnet 4, temp=0)
- specialists/assessment-expert.service.ts: 评估专家 (Sonnet 4, temp=0)
- specialists/strategist.service.ts: 策略顾问 (Sonnet 4, temp=0.3)
- specialists/objection-handler.service.ts: 异议处理 (Sonnet 4, temp=0.2)
- specialists/case-analyst.service.ts: 案例分析 (Haiku, temp=0)
- specialists/memory-manager.service.ts: 记忆管理 (Haiku, temp=0)
- prompts/coordinator-system-prompt.ts: 协调器 Prompt(1095行,13章)
- prompts/{policy,assessment,strategist,objection,case,memory}-*-prompt.ts: 各专家 Prompt
- tools/coordinator-tools.ts: 16个工具定义(6 Agent 调用 + 10 直接工具)
- tools/tool-execution-queue.ts: 并发执行队列(isConcurrencySafe 控制并行/串行)
- types/agent.types.ts: Agent 配置、输入/输出类型定义
- types/stream.types.ts: 流式事件类型(含 agent_start/complete/coordinator_thinking)
- types/context.types.ts: 上下文注入类型
- agents.module.ts: NestJS 模块注册

### 前端 Agent 状态展示 (1个)
- AgentStatusIndicator.tsx: 多 Agent 工作状态组件(含动画)

## 修改文件 (15个)

### 后端集成
- conversation.service.ts: 切换到 CoordinatorAgentService
- conversation.gateway.ts: 新增 agent_start/agent_complete/coordinator_thinking 事件
- claude.module.ts: 引入 AgentsModule
- agents.module.ts: 注册 ImmigrationToolsService(复用旧版生产测试的工具实现)
- knowledge-client.service.ts: 新增 search()/getUserContext() 便捷方法

### 旧代码标记 @deprecated
- claude-agent.service.ts, claude-agent-v2.service.ts
- strategy-engine.service.ts, intent-classifier.ts, response-gate.ts

### 前端适配
- chatStore.ts: 新增 ActiveAgent/CompletedAgent/CoordinatorPhase 状态
- useChat.ts: 新增 WebSocket 事件处理
- ChatWindow.tsx: 集成 AgentStatusIndicator
- globals.css: 新增 agentPulse/agentSlideIn 动画

### 共享类型
- conversation.types.ts: 新增 AGENT_START/AGENT_COMPLETE/COORDINATOR_THINKING 事件

## 核心设计决策

1. **新旧结合**: Coordinator 的 10 个直接工具委托给旧版 ImmigrationToolsService
   (经过生产测试的 Google Search、汇率 API、新闻 API 等),6 个 Agent 调用工具
   走新的 Specialist Agent 系统
2. **递归 async generator**: agent-loop 支持流式输出 + 工具递归 + 成本/轮次控制
3. **并行 Agent 执行**: ToolExecutionQueue 根据 isConcurrencySafe 自动并行/串行
4. **Prompt 缓存**: 所有 Agent 的 system prompt 使用 cache_control: ephemeral
5. **速率限制重试**: 429/529 指数退避,最多 2 次
6. **向后兼容**: LegacyConversationContext 类型别名,StreamChunk 扩展不破坏现有结构

hailin eb1cb9c496 fix(orm): add explicit PostgreSQL column types for nullable fields
Fixed TypeORM DataTypeNotSupportedError for "Object" type in PostgreSQL.

## Issues Fixed

1. **user-service/UserORM**
   - fingerprint: varchar(255)
   - phone: varchar(20)
   - nickname: varchar(100)
   - avatar: varchar(500)

2. **payment-service/PaymentORM**
   - transactionId: varchar(255)
   - currency: varchar(10)
   - expiresAt: timestamptz
   - paidAt: timestamptz

3. **conversation-service/MessageORM**
   - inputTokens: int
   - outputTokens: int

## Root Cause
@Column({ nullable: true }) without explicit `type` defaults to Object,
which PostgreSQL doesn't support.

hailin afd707d15f refactor(services): implement 4-layer Clean Architecture for all backend services
Refactored all 6 backend services to 4-layer Clean Architecture pattern
following knowledge-service as reference implementation.

## Architecture Pattern (4-Layer)

```

│   ├── entities/        # Domain entities (no ORM decorators)
│   ├── repositories/    # Repository interfaces + Symbol tokens
│   └── value-objects/   # Enums and value types

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

hailin c768e2aa53 fix(agent): stricter max_tokens calculation for response length control
- Reduce tokensPerChar from 2 to 1.8 for more accurate Chinese token estimation
- Use min() instead of max() to enforce upper limits on token counts
- CHAT: max 200 tokens (was min 256)
- SIMPLE_QUERY: max 600 tokens (was min 512)
- CLARIFICATION: max 300 tokens (was min 256)
- CONFIRMATION: max 400 tokens (was min 384)
- DEEP_CONSULTATION: 800-1600 tokens (was 1024-4096)
- ACTION_NEEDED: 500-1000 tokens (was 768-2048)

This should result in more concise AI responses that better match
the intent classifier's suggested length limits.

hailin d9b4c72894 feat(agent): implement 3-layer architecture for better response quality
Implement a three-layer architecture to improve AI response quality:

Layer 1 - Intent Classifier (intent-classifier.ts):
- Classifies user intent into 6 types: SIMPLE_QUERY, DEEP_CONSULTATION,
  ACTION_NEEDED, CHAT, CLARIFICATION, CONFIRMATION
- Determines suggested response length based on intent type
- Detects follow-up questions and extracts entities (visa types, etc.)
- Uses keyword matching for fast classification (no API calls)

Layer 2 - ReAct Agent (system-prompt.ts):
- Adds ReAct thinking framework to system prompt
- 4-step process: Understand -> Evaluate -> Act -> Generate
- Emphasizes concise responses, avoids redundant phrases
- Injects intent classification results to guide response strategy

Layer 3 - Response Gate (response-gate.ts):
- Quality checks: length, relevance, redundancy, completeness, tone
- Logs gate results for analysis and future optimization
- Can trim responses and remove redundant expressions

Integration (claude-agent.service.ts):
- Integrates all 3 layers in sendMessage flow
- Dynamically adjusts max_tokens based on intent type
- Collects full response for gate analysis

Documentation:
- Added AGENT_THREE_LAYER_ARCHITECTURE.md with detailed design docs

hailin 2069a3cf0a fix(evolution): resolve pgvector type conflict in SystemExperienceORM
The embedding column was declared as float[] but the database uses
VECTOR(1536) from pgvector. TypeORM doesn't natively support pgvector
types, causing 500 errors when querying the system_experiences table.

Fixed by:
- Changed column type to 'text' with select: false
- This prevents TypeORM from trying to select/map the vector column
- The embedding field is only used for similarity searches via raw SQL
