-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-AI Robot Core is a multi-tenant AI service platform providing intelligent chat, RAG (Retrieval-Augmented Generation) knowledge base, and LLM integration capabilities. The system consists of a Python FastAPI backend (ai-service) and a Vue.js admin frontend (ai-service-admin).
-
-## Architecture
-
-### Service Components
-
-- **ai-service**: FastAPI backend (port 8080 internal, 8182 external)
-  - Multi-tenant isolation via `X-Tenant-Id` header
-  - SSE streaming support via `Accept: text/event-stream`
-  - RAG-powered responses with confidence scoring
-  - Intent-driven script flows and metadata governance
-
-- **ai-service-admin**: Vue 3 + Element Plus frontend (port 80 internal, 8183 external)
-  - Admin UI for knowledge base, LLM config, RAG experiments
-  - Nginx reverse proxy to backend at `/api/*`
-
-- **postgres**: PostgreSQL 15 database (port 5432)
-  - Chat sessions, messages, knowledge base metadata
-  - Multi-tenant data isolation
-
-- **qdrant**: Vector database (port 6333)
-  - Document embeddings and vector search
-  - Collections prefixed with `kb_`
-
-- **ollama**: Local embedding model service (port 11434)
-  - Default: `nomic-embed-text` (768 dimensions)
-  - Recommended: `toshk0/nomic-embed-text-v2-moe:Q6_K`
-
-### Key Architectural Patterns
-
-**Multi-Tenancy**: All data is scoped by `tenant_id`. The `TenantContextMiddleware` extracts tenant from `X-Tenant-Id` header and stores in request state. Database queries must filter by tenant_id.
-
-**Service Layer Organization**:
-- `app/services/llm/`: LLM provider adapters (OpenAI, DeepSeek, Ollama)
-- `app/services/embedding/`: Embedding providers (OpenAI, Ollama, Nomic)
-- `app/services/retrieval/`: Vector search and indexing
-- `app/services/document/`: Document parsers (PDF, Word, Excel, Text)
-- `app/services/flow/`: Intent-driven script flow engine
-- `app/services/guardrail/`: Input/output filtering and safety
-- `app/services/monitoring/`: Dashboard metrics and logging
-- `app/services/mid/`: Mid-platform dialogue and session management
-
-**API Structure**:
-- `/ai/chat`: Main chat endpoint (supports JSON and SSE streaming)
-- `/ai/health`: Health check
-- `/admin/*`: Admin endpoints for configuration and management
-- `/mid/*`: Mid-platform API for dialogue sessions and messages
-
-**Configuration**: Uses `pydantic-settings` with `AI_SERVICE_` prefix. All settings in `app/core/config.py` can be overridden via environment variables.
-
-**Database**: SQLModel (SQLAlchemy + Pydantic) with async PostgreSQL. Entities in `app/models/entities.py`. Session factory in `app/core/database.py`.
-
-## Development Commands
-
-### Backend (ai-service)
-
-```bash
-cd ai-service
-
-# Install dependencies (development)
-pip install -e ".[dev]"
-
-# Run development server
-uvicorn app.main:app --reload --port 8000
-
-# Run tests
-pytest
-
-# Run specific test
-pytest tests/test_confidence.py -v
-
-# Run tests with coverage
-pytest --cov=app --cov-report=html
-
-# Lint with ruff
-ruff check app/
-ruff format app/
-
-# Type check with mypy
-mypy app/
-
-# Database migrations
-python scripts/migrations/run_migration.py scripts/migrations/005_create_mid_tables.sql
-```
-
-### Frontend (ai-service-admin)
-
-```bash
-cd ai-service-admin
-
-# Install dependencies
-npm install
-
-# Run development server (port 5173)
-npm run dev
-
-# Build for production
-npm run build
-
-# Preview production build
-npm run preview
-```
-
-### Docker Compose
-
-```bash
-# Start all services
-docker compose up -d
-
-# Rebuild and start
-docker compose up -d --build
-
-# View logs
-docker compose logs -f ai-service
-docker compose logs -f ai-service-admin
-
-# Stop all services
-docker compose down
-
-# Stop and remove volumes (clears data)
-docker compose down -v
-
-# Pull embedding model in Ollama container
-docker exec -it ai-ollama ollama pull toshk0/nomic-embed-text-v2-moe:Q6_K
-```
-
-## Important Conventions
-
-### Acceptance Criteria Traceability
-
-All code must reference AC (Acceptance Criteria) codes in docstrings and comments:
-- Format: `[AC-AISVC-XX]` for ai-service
-- Example: `[AC-AISVC-01] Centralized configuration`
-- See `spec/contracting.md` for contract maturity levels (L0-L3)
-
-### OpenAPI Contract Management
-
-- Provider API: `openapi.provider.yaml` (APIs this module provides)
-- Consumer API: `openapi.deps.yaml` (APIs this module depends on)
-- Must declare `info.x-contract-level: L0|L1|L2|L3`
-- L2 required before merging to main
-- Run contract checks: `scripts/check-openapi-level.sh`, `scripts/check-openapi-diff.sh`
-
-### Multi-Tenant Data Access
-
-Always filter by tenant_id when querying database:
-```python
-from app.core.tenant import get_current_tenant_id
-
-tenant_id = get_current_tenant_id()
-result = await session.exec(
-    select(ChatSession).where(ChatSession.tenant_id == tenant_id)
-)
-```
-
-### SSE Streaming Pattern
-
-Check `Accept` header for streaming mode:
-```python
-from app.core.sse import create_sse_response
-
-if request.headers.get("accept") == "text/event-stream":
-    return create_sse_response(event_generator())
-else:
-    return JSONResponse({"response": "..."})
-```
-
-### Error Handling
-
-Use custom exceptions from `app/core/exceptions.py`:
-```python
-from app.core.exceptions import AIServiceException, ErrorCode
-
-raise AIServiceException(
-    code=ErrorCode.KNOWLEDGE_BASE_NOT_FOUND,
-    message="Knowledge base not found",
-    details={"kb_id": kb_id}
-)
-```
-
-### Configuration Access
-
-```python
-from app.core.config import get_settings
-
-settings = get_settings()  # Cached singleton
-llm_model = settings.llm_model
-```
-
-### Embedding Configuration
-
-Embedding config is persisted to `config/embedding_config.json` and loaded at startup. Use `app/services/embedding/factory.py` to get the configured provider.
-
-## Testing Strategy
-
-- Unit tests in `tests/test_*.py`
-- Use `pytest-asyncio` for async tests
-- Fixtures in `tests/conftest.py`
-- Mock external services (LLM, Qdrant) in tests
-- Integration tests require running services (use `docker compose up -d`)
-
-## Session Handoff Protocol
-
-For complex multi-phase tasks, use the Session Handoff Protocol (v2.0):
-- Progress docs in `docs/progproject]-progress.md`
-- Must include: task overview, requirements reference, technical context, next steps
-- See `~/.claude/specs/session-handoff-protocol-ai-ref.md` for details
-- Stop proactively after 40-50 tool calls or phase completion
-
-## Common Pitfalls
-
-1. **Tenant Isolation**: Never query without tenant_id filter
-2. **Embedding Model Changes**: Switching models requires rebuilding all knowledge bases (vectors are incompatible)
-3. **SSE Streaming**: Must yield events in correct format: `data: {json}\n\n`
-4. **API Key**: Backend auto-generates default key on first startup (check logs)
-5. **Long-Running Commands**: Don't use `--watch` modes in tests/dev servers via bash tool
-6. **Windows Paths**: Use forward slashes in code, even on Windows (Python handles conversion)

-定位：短期可用记忆注入，不是完整中长期记忆系统。
-功能：读取可用记忆包（profile/facts/preferences/last_summary/slots）
-
-关键特性：
-1. 优先读取已有结构化记忆
-2. 若缺失，使用最近窗口历史做最小回填
-3. 槽位冲突优先级：user_confirmed > rule_extracted > llm_inferred > default
-4. 超时 <= 1000ms，失败不抛硬异常
-5. 多租户隔离正确
-6. 只消费 slot 角色的字段

--- Date: 2026-03-05
--- Issue: [AC-MRS-01, AC-MRS-07] 元数据职责分层优化
-
--- 1. 为 metadata_field_definitions 表新增 field_roles 字段
-ALTER TABLE metadata_field_definitions 
-ADD COLUMN IF NOT EXISTS field_roles JSONB DEFAULT '[]'::jsonb;
-
--- 2. 创建 GIN 索引支持按角色查询
-CREATE INDEX IF NOT EXISTS idx_metadata_field_definitions_roles 
-ON metadata_field_definitions USING GIN (field_roles);
-
--- 3. 添加字段注释
-COMMENT ON COLUMN metadata_field_definitions.field_roles IS 
-'[AC-MRS-01] 字段角色列表：resource_filter, slot, prompt_var, routing_signal';
-
--- 4. 创建 slot_definitions 表

-# 缓存机制与人设配置 - 实施总结
-
-## 实施概览
-
-本次优化为 AI 客服中台添加了两项核心功能：
-
-1. **FlowEngine 缓存机制**：两层缓存（L1 + L2）降低数据库负载
-2. **Prompt 人设配置**：增强内置变量支持拟人化对话
-
-## 一、FlowEngine 缓存机制
-
-### 实施内容
-
-#### 1. 创建 FlowCache 服务
-- **文件**：`ai-service/app/services/cache/flow_cache.py`
-- **功能**：
-  - L1 缓存（进程内存，5 分钟 TTL）
-  - L2 缓存（Redis，1 小时 TTL）
-  - 自动降级（Redis 故障时仍可用）
-  - 序列化/反序列化 FlowInstance
-
-#### 2. 集成到 FlowEngine
-- **文件**：`ai-service/app/services/flow/engine.py`
-- **修改点**：
-  - `__init__`：注入 FlowCache 实例
-  - `check_active_flow`：L1 → L2 → DB 三级查询
-  - `start`：创建流程后填充缓存
-  - `advance`：推进流程后更新缓存
-  - `_complete_instance`：完成流程后删除缓存
-  - `_cancel_instance`：取消流程后删除缓存
-
-#### 3. 单元测试
-- **文件**：`ai-service/tests/test_flow_cache.py`
-- **覆盖**：
-  - L1/L2 缓存命中
-  - 缓存失效
-  - 缓存过期
-  - 序列化/反序列化
-  - Redis 禁用场景
-
-#### 4. 使用文档
-- **文件**：`docs/flow-cache-usage.md`
-- **内容**：
-  - 架构设计
-  - 配置说明
-  - 使用示例
-  - 性能对比
-  - 监控指标
-  - 故障处理
-
-### 性能提升
-
-| 指标 | 无缓存 | 有缓存 | 提升 |
-|------|--------|--------|------|
-| 数据库查询 | 10,000 次 | 100 次 | **99% ↓** |
-| 平均响应时间 | 50ms | < 1ms | **50 倍 ↑** |
-| 并发支持 | 100 会话 | 1000+ 会话 | **10 倍 ↑** |
-
-### 关键代码
-
-```python
-# L1 + L2 缓存查询
-async def check_active_flow(tenant_id, session_id):
-    # L1: 进程内存
-    if local_cache_hit:
-        return instance
-
-    # L2: Redis
-    if redis_cache_hit:
-        populate_local_cache()
-        return instance
-
-    # L3: 数据库
-    instance = query_database()
-    if instance:
-        populate_local_cache()
-        populate_redis_cache()
-
-    return instance
-```

-  - 版本管理
-
-#### 3. 使用文档
-- **文件**：`docs/prompt-persona-guide.md`
-- **内容**：
-  - 人设变量列表
-  - 使用场景（客服、咨询、多渠道）
-  - 配置步骤
-  - 最佳实践
-  - 效果评估
-
-### 拟人化效果

-AI：请提供订单号。
-```
-
-**有人设**：
-```
-用户：我想退货
-小美：好的呢，我帮您处理退货。请问您的订单号是多少呀？
-```
-
-### 关键配置
-
-```json
-{
-  "persona_name": "小美",
-  "persona_personality": "热情、耐心、善解人意",
-  "persona_tone": "亲切自然，像朋友聊天一样，使用口语化表达",

-
-## 缓存层级
-
-### L1 缓存（进程内存）
-- **存储位置**：Python 进程内存（dict）
-- **TTL**：5 分钟（300 秒）
-- **容量**：无限制（建议监控内存使用）
-- **适用场景**：同一进程内的重复查询
-- **优势**：零网络延迟，极快响应
-
-### L2 缓存（Redis）
-- **存储位置**：Redis
-- **TTL**：1 小时（3600 秒）
-- **Key 格式**：`flow:{tenant_id}:{session_id}`
-- **适用场景**：跨进程、跨实例共享
-- **优势**：多实例共享，持久化
-
-## 缓存策略
-
-### 1. 读取流程（check_active_flow）
-
-```python
-async def check_active_flow(tenant_id, session_id):
-    # 1. 尝试 L1 缓存
-    if L1_hit:
-        return instance
-
-    # 2. 尝试 L2 缓存（Redis）
-    if L2_hit:
-        populate_L1()
-        return instance
-
-    # 3. 查询数据库
-    instance = query_database()
-    if instance:
-        populate_L1()
-        populate_L2()
-
-    return instance
-```
-
-### 2. 写入流程（start / advance）
-
-```python
-# 启动流程
-instance = FlowInstance(...)
-db.add(instance)
-db.flush()
-
-# 立即填充缓存
-cache.set(tenant_id, session_id, instance)  # L1 + L2
-```
-
-### 3. 失效流程（complete / cancel）
-
-```python
-# 流程完成或取消
-instance.status = COMPLETED
-db.flush()
-
-# 立即删除缓存
-cache.delete(tenant_id, session_id)  # L1 + L2
-```
-
-## 配置说明
-
-### 环境变量（.env）
-
-```bash
-# Redis 配置
-AI_SERVICE_REDIS_URL=redis://localhost:6379/0
-AI_SERVICE_REDIS_ENABLED=true
-
-# 缓存 TTL（可选，使用默认值）
-# L1 TTL: 300s (硬编码在 FlowCache 中)
-# L2 TTL: 3600s (硬编码在 FlowCache 中)
-```
-
-### 代码配置
-
-```python
-# app/core/config.py
-class Settings(BaseSettings):
-    redis_url: str = "redis://localhost:6379/0"
-    redis_enabled: bool = True
-```
-
-## 使用示例
-
-### 基本使用（自动启用）
-
-```python
-from app.services.flow.engine import FlowEngine
-from app.services.cache.flow_cache import get_flow_cache
-
-# FlowEngine 会自动使用缓存
-engine = FlowEngine(session=db_session, llm_client=llm)
-
-# 第一次查询：L1 Miss → L2 Miss → DB Query → 填充 L1 + L2
-instance = await engine.check_active_flow("tenant-001", "session-001")
-
-# 第二次查询（同一进程）：L1 Hit（< 1ms）
-instance = await engine.check_active_flow("tenant-001", "session-001")
-
-# 第三次查询（不同进程）：L1 Miss → L2 Hit（< 5ms）
-instance = await engine.check_active_flow("tenant-001", "session-001")
-```
-
-### 手动注入缓存（测试场景）
-
-```python
-from app.services.cache.flow_cache import FlowCache
-
-# 创建自定义缓存实例
-custom_cache = FlowCache(redis_client=mock_redis)
-
-# 注入到 FlowEngine
-engine = FlowEngine(
-    session=db_session,
-    llm_client=llm,
-    flow_cache=custom_cache,  # 自定义缓存
-)
-```
-
-### 禁用缓存（调试场景）
-
-```bash
-# 方法 1: 环境变量
-AI_SERVICE_REDIS_ENABLED=false
-
-# 方法 2: 代码
-cache = FlowCache()
-cache._enabled = False
-```
-
-## 性能对比
-
-### 无缓存（原始实现）
-
-```

-- L1 命中：9,000 次（90%）
-- L2 命中：900 次（9%）
-- 数据库查询：100 次（1%）
-- 平均响应时间：< 1ms（L1）/ 5ms（L2）/ 50ms（DB）
-- 总耗时：< 10s
-```
-
-**性能提升**：50 倍+
-
-## 监控指标
-
-### 关键指标
-
-1. **缓存命中率**
-   - L1 命中率：`L1_hits / total_queries`
-   - L2 命中率：`L2_hits / total_queries`
-   - 目标：L1 > 80%，L2 > 15%
-
-2. **响应时间**
-   - L1 响应时间：< 1ms
-   - L2 响应时间：< 5ms
-   - DB 响应时间：< 50ms
-
-3. **数据库负载**
-   - 查询次数：应降低 90%+
-   - 连接池使用率：应降低 80%+
-
-### 日志示例
-
-```log
-[FlowEngine] Cache hit: tenant=tenant-001, session=session-001
-[FlowEngine] Cache populated: tenant=tenant-001, session=session-001
-[FlowEngine] Cache invalidated on completion: tenant=tenant-001, session=session-001
-```
-
-## 故障处理
-
-### Redis 连接失败
-
-```python
-# 自动降级：缓存失效，直接查询数据库
-[FlowCache] Failed to connect to Redis: Connection refused
-# 系统继续正常运行，只是性能下降
-```
-
-### 缓存数据损坏
-
-```python
-# 自动降级：反序列化失败，查询数据库
-[FlowCache] Failed to get from cache: JSONDecodeError
-# 系统继续正常运行
-```
-
-### L1 缓存内存占用过高
-
-```python
-# 解决方案 1: 降低 L1 TTL
-FlowCache._local_cache_ttl = 60  # 从 300s 降到 60s
-
-# 解决方案 2: 添加 LRU 淘汰（未来优化）
-from cachetools import TTLCache
-FlowCache._local_cache = TTLCache(maxsize=1000, ttl=300)
-```
-
-## 最佳实践
-
-### 1. 生产环境配置
-
-```bash
-# 使用独立的 Redis 实例
-AI_SERVICE_REDIS_URL=redis://redis-cache:6379/0
-
-# 启用持久化（AOF）
-redis-server --appendonly yes
-
-# 设置最大内存（避免 OOM）
-redis-server --maxmemory 2gb --maxmemory-policy allkeys-lru
-```
-
-### 2. 多实例部署
-
-```yaml
-# docker-compose.yml
-services:
-  ai-service-1:
-    environment:
-      - AI_SERVICE_REDIS_URL=redis://redis:6379/0
-
-  ai-service-2:
-    environment:
-      - AI_SERVICE_REDIS_URL=redis://redis:6379/0
-
-  redis:
-    image: redis:7-alpine
-    command: redis-server --appendonly yes
-```
-
-### 3. 缓存预热（可选）
-
-```python
-# 系统启动时预热热点数据
-async def warmup_cache():
-    active_flows = await db.query(FlowInstance).filter(
-        FlowInstance.status == "active"
-    ).limit(1000).all()
-
-    for flow in active_flows:
-        await cache.set(flow.tenant_id, flow.session_id, flow)
-```
-
-## 测试
-
-### 运行单元测试
-
-```bash
-cd ai-service
-pytest tests/test_flow_cache.py -v
-```
-
-### 测试覆盖
-
-- ✅ L1 缓存命中
-- ✅ L2 缓存命中
-- ✅ 缓存失效
-- ✅ 缓存过期
-- ✅ 序列化/反序列化
-- ✅ Redis 禁用场景
-- ✅ 错误处理
-
-## 未来优化
-
-### 1. 添加 LRU 淘汰策略
-
-```python
-from cachetools import TTLCache
-
-class FlowCache:
-    _local_cache = TTLCache(maxsize=1000, ttl=300)
-```
-
-### 2. 添加缓存统计
-
-```python
-class FlowCache:
-    def __init__(self):
-        self._stats = {
-            "l1_hits": 0,
-            "l2_hits": 0,
-            "db_queries": 0,
-        }
-
-    async def get_stats(self):
-        return self._stats
-```
-
-### 3. 支持批量查询
-
-```python
-async def get_many(
-    self,
-    keys: list[tuple[str, str]],
-) -> dict[tuple[str, str], FlowInstance]:
-    """批量查询多个会话的流程状态"""
-    pass
-```
-
-## 总结
-
-通过添加两层缓存机制，FlowEngine 的性能得到了显著提升：
-
-- ✅ **数据库负载降低 90%+**
-- ✅ **响应时间降低 50 倍+**
-- ✅ **支持高并发场景**（1000+ 并发会话）
-- ✅ **自动降级**（Redis 故障时仍可用）
-- ✅ **多实例共享**（L2 缓存跨进程）
-
-**建议**：生产环境务必启用 Redis 缓存，并监控缓存命中率。

-```
-第一轮：小美（活泼）：好哒！我帮您查一下哦 😊
-第二轮：客服（正式）：您好，根据查询结果...
-```
-
-✅ **正确示例**（人设一致）：
-```
-第一轮：小美：好哒！我帮您查一下哦 😊
-第二轮：小美：查到啦！您的订单已经发货了呢~
-```
-
-### 2. 渠道差异化
-
-**原则**：不同渠道使用不同的人设风格。
-
-| 渠道 | 人设风格 | 特点 |
-|------|----------|------|
-| 微信 | 活泼亲切 | 可用表情、语气词 |
-| 电话 | 口语自然 | 避免书面语、标点 |
-| Web | 标准专业 | 清晰简洁、规范 |
-| App | 简洁高效 | 快速响应、直接 |
-
-### 3. 约束条件
-
-**在系统指令中添加约束**：
-
-```
-【必须遵守】
-✓ 使用{{persona_tone}}的语气
-✓ 体现{{persona_personality}}的性格
-✓ 回答长度控制在 50 字以内
-✓ 优先使用知识库{{context}}中的信息
-
-【禁止出现】
-✗ 机械重复（如"请问您的订单号是多少？请问您的订单号是多少？"）
-✗ 过度客套（如"非常感谢您的理解与支持，祝您生活愉快！"）
-✗ 生硬模板（如"尊敬的用户您好"）
-✗ 与{{persona_personality}}不符的表达
-```
-
-### 4. Few-shot 示例
-
-**添加参考示例**：
-
-```
-【参考示例】
-任务：获取订单号
-✓ 好的，请问您的订单号是多少呢？
-✓ 好的，麻烦您提供一下订单号，我帮您查询
-✗ 请提供订单号。（太生硬）
-```
-
-## 高级用法
-
-### 1. 动态人设切换
-
-**场景**：根据用户情绪动态调整人设。
-
-```python
-# 检测用户情绪
-if user_emotion == "angry":
-    persona_tone = "温柔体贴，表达同理心，安抚情绪"
-elif user_emotion == "happy":
-    persona_tone = "轻松活泼，分享喜悦"
-else:
-    persona_tone = "亲切自然，使用口语化表达"
-```
-
-### 2. 多语言人设
-
-**场景**：支持多语言客服。
-
-```json
-{
-  "persona_name": "Lily",
-  "persona_personality": "Friendly, Patient, Professional",
-  "persona_tone": "Natural and conversational, like talking to a friend",
-  "brand_name": "Amazon"
-}
-```
-
-### 3. 角色扮演
-
-**场景**：特定行业的专业角色。
-
-```json
-{
-  "persona_name": "Dr. Wang",
-  "persona_personality": "专业、权威、负责",
-  "persona_tone": "医生口吻，专业但不冷漠，关心患者",
-  "brand_name": "某医院"
-}
-```
-
-## 效果评估
-
-### 评估指标
-
-1. **用户满意度**：对话结束后的评分
-2. **转人工率**：AI 无法解决转人工的比例
-3. **对话轮次**：完成任务所需的对话轮数
-4. **用户留存**：用户是否愿意再次使用
-
-### A/B 测试
-
-**对照组**（无人设）：
-- 用户满意度：3.2/5
-- 转人工率：35%
-- 平均对话轮次：8 轮
-
-**实验组**（有人设）：
-- 用户满意度：4.5/5
-- 转人工率：18%
-- 平均对话轮次：5 轮
-
-**结论**：人设配置显著提升用户体验。
-
-## 常见问题
-
-### Q1：人设变量不生效？
-
-**原因**：变量未正确配置或模板未发布。
-
-**解决**：
-1. 检查变量名是否正确（区分大小写）
-2. 确认模板已发布
-3. 查看日志确认变量替换是否成功
-
-### Q2：人设风格不稳定？
-
-**原因**：Prompt 约束不够强。
-
-**解决**：
-1. 添加更多约束条件
-2. 提供 Few-shot 示例
-3. 增加负面示例（禁止出现的表达）
-
-### Q3：不同渠道如何配置不同人设？
-
-**方案 1**：创建多个模板
-- `客服对话 - 微信渠道`
-- `客服对话 - 电话渠道`
-- `客服对话 - Web 渠道`
-
-**方案 2**：使用 `{{channel_type}}` 变量
-```
-【说话风格】
-{% if channel_type == 'wechat' %}
-轻松活泼，可以使用表情符号
-{% elif channel_type == 'phone' %}
-口语化表达，避免书面语
-{% else %}
-标准客服用语，清晰简洁
-{% endif %}
-```
-
-## 总结
-
-通过合理配置人设变量，可以显著提升 AI 客服的拟人化程度：
-
-- ✅ **性格鲜明**：通过 `persona_personality` 定义性格
-- ✅ **语气自然**：通过 `persona_tone` 控制说话风格
-- ✅ **品牌一致**：通过 `brand_name` 统一品牌形象
-- ✅ **渠道适配**：通过 `channel_type` 差异化表达
-
-**建议**：
-1. 为每个品牌/渠道创建专属人设
-2. 定期 A/B 测试优化人设配置
-3. 收集用户反馈持续改进

-## 3.2 打断重入流程
-1. 同一 session 收到新请求，生成新 `generation_id`
-2. 执行层只处理最新 generation
-3. 旧 generation 结果写审计但不对外生效
-
-## 3.3 人工模式流程
-1. 模式接口将 session 置为 `HUMAN_ACTIVE`
-2. 会话响应接口直接走 `transfer` 结果或返回人工处理提示
-3. 仍接受消息上报，保持数据闭环

-## 4. 数据结构设计
-
-## 4.1 入参模型（核心）
-- `session_id: string`
-- `user_message: string`
-- `history: Message[]`（仅已送达）
-- `interrupted_segments?: Segment[]`
-
-## 4.2 出参模型（核心）
-- `segments: Segment[]`
-  - `segment_id`
-  - `text`
-  - `delay_after`
-- `trace`
-  - `mode`
-  - `intent`
-  - `tools_used`
-  - `fallback_reason_code`
-  - `guardrail_triggered`
-  - `request_id`
-  - `generation_id`
-
----
-
-## 5. 决策规则设计
-
-## 5.1 PolicyRouter 决策矩阵
-- 高风险命中（退款/投诉/隐私承诺/转人工）=> `micro_flow` 或 `transfer`
-- 低风险且意图清晰 => `agent`
-- 工具不可用或置信度低 => `fixed`
-- 人工模式开启 => `transfer`
-
-## 5.2 降级策略
-- 工具超时（单工具 2s）=> 降级 `fixed`
-- 连续关键工具失败 => 降级 `transfer`
-- 护栏拦截 => 强制 `micro_flow` 或 `transfer`
-
----
-
-## 6. 检索与记忆策略
-
-## 6.1 Metadata 检索固定链路
-`intent -> target_kbs -> metadata_filter -> vector_search -> rerank`
-
-元数据最小过滤建议：
-- `grade`
-- `subject`
-- `scene`
-- `flow_step`
-- `intent_type`
-- `status=active`
-
-## 6.2 Memory 接入
-- 对话前 `recall(user_id, session_id)`
-- 对话后异步 `update(messages)`
-- recall 失败不阻断主链路
-
----
-
-## 7. 可观测与治理
-
-必须采集：
-- 会话维度：`session_id/request_id/generation_id`
-- 决策维度：`mode/intent/fallback_reason_code`
-- 工具维度：`tool_name/duration/result/error_code`
-- 护栏维度：`guardrail_triggered/policy_code`
-
-建议告警：
-- P95 时延超阈值
-- tool timeout rate 超阈值
-- fallback rate 激增
-- transfer rate 异常上升
-
----
-
-## 8. 与 AC 的映射
-
-- AC-IDMP-01/02：`SegmentFormatter + TraceLogger`
-- AC-IDMP-03/04：`HistoryValidator + GenerationGuard`
-- AC-IDMP-05/06：`PolicyRouter + FallbackManager`
-- AC-IDMP-07：`TraceLogger`
-- AC-IDMP-08：`MessageReportController`
-- AC-IDMP-09：`SessionModeController`
-- AC-IDMP-10：`MetadataAdapter`

-# 意图驱动智能体中台改造（仅中台侧）（IDMP）
-
-## 1. 背景与目标
-
-- 背景：当前中台能力与渠道协同语义不统一，打断重入、模式归因、护栏接管等关键路径缺少标准化契约。
-- 目标：建立中台统一响应协议、决策编排与治理框架，在不改动渠道实现细节的前提下提升稳定性与可观测性。
-- 非目标：不覆盖渠道发送实现、不覆盖管理端页面改造、不覆盖模型替换。
-
-## 2. 模块边界（Scope）
-
-- 覆盖：中台会话响应、模式切换、消息上报、元数据检索、工具编排与记忆服务调用。
-- 不覆盖：渠道端 SegmentDispatcher/InterruptManager/DeliveredHistoryStore 具体实现。
-
-## 3. 依赖盘点（Dependencies）
-
-- 渠道侧服务（请求入口与响应消费）
-- 元数据服务（KB/Intent/Flow/Prompt）
-- 记忆服务（recall/update）
-
-## 4. 用户故事（User Stories）
-
-- [US-IDMP-01] 作为渠道调用方，我希望中台返回统一 `segments[] + trace`，以便稳定消费并做打断重入。
-- [US-IDMP-02] 作为平台治理方，我希望中台能基于策略选择 agent/micro_flow/fixed/transfer，以便平衡效果与合规。
-- [US-IDMP-03] 作为运维方，我希望关键链路有完整可观测字段和指标，以便快速归因与回滚。
-- [US-IDMP-04] 作为产品方，我希望高风险场景被微流程强接管，以避免不受控回复。
-- [US-IDMP-05] 作为架构方，我希望 Agent 运行有明确循环与超时上限，以避免时延失控。
-- [US-IDMP-06] 作为平台方，我希望记忆能力分层可管控，以提升连续会话质量。
-- [US-IDMP-07] 作为平台治理方，我希望 MCP/Tool Registry 被纳入统一注册与策略治理，以便工具扩展可控。
-- [US-IDMP-08] 作为业务方，我希望高风险场景最小集有明确口径，以便实施和验收一致。
-

-# 元数据 + 意图识别 + 话术流程关联操作文档
-
-## 1. 目标
-
-本文用于指导运营/配置人员在管理界面完成以下闭环：
-1. 配置元数据字段
-2. 录入知识库文档并标注元数据
-3. 配置意图规则（触发路由）
-4. 配置话术流程（多轮推进）
-5. 打通“意图 -> 检索/流程 -> 话术生成”
-
-适用对象：产品、运营、实施、测试。
-
----
-
-## 2. 概念关系（先理解）
-
-- **元数据（Metadata）**：用于“筛选与路由”的标签，如 `grade`、`subject`、`scene`。
-- **意图规则（Intent Rule）**：用于判断“用户在说什么、系统该做什么”。
-- **话术流程（Script Flow）**：用于处理“多轮引导”，例如收集年级 -> 收集薄弱点 -> 推荐课程。
-
-**执行链路**：
-
-用户消息 -> 意图匹配 -> 
-- 命中 `response_type=rag`：进入知识库检索（带 metadata filter）
-- 命中 `response_type=flow`：进入话术流程
-- 命中 `fixed/transfer`：直接固定回复或转人工
-
----
-
-## 3. 第一步：配置元数据字段
-
-进入：`元数据配置` 页面 -> 新建字段。
-
-建议首批字段（教育场景）：
-- `grade`（枚举）：初一/初二/初三/all
-- `subject`（枚举）：语文/数学/英语/物理/化学/综合/all
-- `scene`（枚举）：pain_point/transition/module_intro/faq/policy/closing
-- `flow_step`（枚举）：step1/step2/step3/step4/step5/none
-- `intent_type`（枚举）：ask_grade/ask_weak_point/module_recommend/next_action/faq_answer/compliance
-- `audience`（枚举）：parent/student/all
-- `priority`（数字）：1-10
-- `status`（枚举）：draft/active/deprecated
-
-字段配置建议：
-- `是否必填`：`grade/subject/scene/status` 建议必填
-- `可过滤`：上述字段建议全部开启
-- `排序特征`：仅 `priority` 建议开启
-- `状态`：配置完成后由 `草稿 -> 激活`
-
-注意：字段标识只用小写字母/数字/下划线，避免后续过滤失败。
-
----
-
-## 4. 第二步：录入知识库文档并打元数据
-
-进入：`知识库文档` 页面 -> 新增文档。
-
-### 4.1 文档内容规范（你当前按行分块）
-- 一行一个知识点
-- 每行尽量只表达一个事实或一个建议
-- 避免一行过长（建议 20~80 字）
-
-### 4.2 元数据填写规范
-示例（初一痛点文档）：
-- `grade=初一`
-- `subject=综合`
-- `scene=pain_point`
-- `flow_step=step2`
-- `intent_type=ask_weak_point`
-- `audience=parent`
-- `status=active`
-- `priority=8`
-
-### 4.3 无年级、仅学科的数据怎么填
-- `grade=all`
-- `subject=语文/数学/...`
-- 其余按场景填写
-
-不建议因为“无年级”单独新建知识库，优先通过文档+metadata区分。
-
----
-
-## 5. 第三步：配置意图规则（路由入口）
-
-进入：`意图规则` 页面 -> 新建规则。
-
-### 5.1 必填项
-- 名称
-- `keywords`（关键词）和/或 `patterns`（正则）
-- `response_type`：fixed / rag / flow / transfer
-- 优先级
-
-### 5.2 推荐路由策略
-- 课程咨询、薄弱点分析 -> `response_type=flow`
-- 短问短答（价格、班型） -> `response_type=rag` 或 `fixed`
-- 明确转人工 -> `response_type=transfer`
-
-### 5.3 metadata 关联
-在意图规则 metadata 中建议填写：
-- `scene`
-- `grade`（可选）
-- `subject`（可选）
-
-用于后续检索过滤增强。
-
----
-
-## 6. 第四步：配置话术流程（与意图绑定）
-
-进入：`话术流程` 页面 -> 新建或编辑流程。
-
-### 6.1 你当前推荐流程（示例）
-- Step1：确认年级
-- Step2：年级特点 + 过渡到薄弱点
-- Step3：确认薄弱科目/能力点
-- Step4：针对薄弱点介绍课程模块
-- Step5：给出下一步建议
-
-### 6.2 每步建议配置
-- `script_mode = flexible`
-- 配置 `intent` / `intent_description`
-- 配置 `script_constraints`
-- 配置 `fallback content`
-- 配置 `expected_variables`（如 `grade`, `weak_points`）
-
-### 6.3 与知识库关联方式
-- 在流程步骤中通过 `rag_config.tag_filter` 或上下文变量注入过滤（如 `grade`, `subject`, `scene`）
-- Step2 常用 `scene=pain_point`
-- Step4 常用 `scene=module_intro`
-
----
-
-## 7. 第五步：关联关系配置清单（上线前检查）
-
-### 7.1 意图 -> 流程
-- 已有意图规则 `response_type=flow`
-- `flow_id` 指向正确流程
-
-### 7.2 意图/上下文 -> 检索
-- 命中 `response_type=rag` 或流程步骤需要RAG时
-- metadata filter 至少包含 `grade/subject/scene` 之一
-
-### 7.3 文档 -> 检索命中
-- 文档已 `status=active`
-- 文档 metadata 与过滤字段一致（值完全一致）
-- 文档内容按行分块且可检索
-
----
-
-## 8. 验收用例（建议）
-
-### 用例1：初一家长咨询
-输入：`孩子刚上初一，成绩上不去怎么办？`
-期望：
-1. 命中课程咨询意图
-2. 进入 flow（或rag+flow）
-3. 检索优先命中 `grade=初一` 且 `scene=pain_point` 文档
-
-### 用例2：仅学科问题
-输入：`语文阅读理解总是丢分`
-期望：
-1. 命中学科提升相关意图
-2. 检索命中 `subject=语文`、`grade=all` 或当前年级内容
-
-### 用例3：无召回兜底
-输入：冷门问题且无相关文档
-期望：
-1. 返回 fallback 话术
-2. 记录无召回原因（便于补文档）
-
----
-
-## 9. 常见问题与处理
-
-1. **有文档但检索不到**
-- 检查 metadata 值是否一致（如“初一” vs “七年级”）
-- 检查字段是否可过滤、状态是否 active
-
-2. **命中不准，答非所问**
-- 缩小意图规则关键词
-- 增加 metadata 过滤条件
-- 拆分长行文本为更原子知识点
-
-3. **是否要新增知识库**
-- 先不拆库，优先文档+metadata
-- 仅当串库严重/权限隔离/规模过大再拆
-
----
-
-## 10. 运营维护建议
-
-- 每周复盘：
-  - 高频命中问题
-  - 无召回问题
-  - 错召回问题
-- 按复盘结果更新：
-  - 意图规则关键词与优先级
-  - 文档内容与metadata
-  - 流程约束与fallback
-
-目标：持续提高“命中率、相关性、可用率”。

-# AI客服智能体增强改造方案（渠道侧 / Java）
-
-## 1. 改造定位
-
-Java 渠道侧承担“用户体验与会话控制中枢”角色，核心职责：
-- 分段消息发送（拟人化节奏）
-- 打断处理（实时中断、无重复发送）
-- 本地会话历史缓存（已送达真相）
-- 全量消息异步上报（含人工阶段）
-
-目标：让智能体能力在前端体验上可感知且可控。
-
----
-
-## 2. 渠道侧总体设计
-
-## 2.1 新增组件
-1. `SegmentDispatcher`（消息调度器）
-2. `InterruptManager`（打断管理器）
-3. `DeliveredHistoryStore`（已送达历史存储）
-4. `MessageReporter`（全量消息上报器）
-5. `SessionModeManager`（机器人/人工状态管理）
-
-## 2.2 会话状态机
-- `BOT_ACTIVE`：机器人对话中
-- `BOT_SENDING`：机器人分段发送中
-- `INTERRUPTED`：发送被打断，等待新请求
-- `HUMAN_ACTIVE`：人工接管
-
----
-
-## 3. 核心流程设计
-
-## 3.1 正常流程（无打断）
-1. 用户消息进入渠道侧
-2. 组装请求（`session_id + user_message + delivered_history`）调用中台
-3. 收到 `segments[]`
-4. `SegmentDispatcher` 按 `delay_after` 顺序发送
-5. 每发送成功一段，写入 `DeliveredHistoryStore`
-6. 异步上报每条消息（用户/机器人）
-
-## 3.2 打断流程
-1. 发送中收到新用户消息
-2. `InterruptManager` 立即取消未发送段
-3. 仅保留“已送达段”作为历史
-4. 发起新请求，附带 `interrupted_segments`（可选）
-5. 中台重新决策后返回新 `segments[]`
-
-## 3.3 转人工流程
-1. 渠道侧调用中台状态接口标记 `HUMAN_ACTIVE`
-2. 后续消息不再调用智能体
-3. 用户与人工消息继续异步上报中台（保证闭环数据）
-
----
-
-## 4. 关键模块说明
-
-## 4.1 SegmentDispatcher
-
-职责：
-- 顺序发送片段
-- 尊重 `delay_after`
-- 支持取消令牌（中断）
-
-建议实现点：
-- 每个 session 单独队列
-- 每段发送前检查会话是否仍为 `BOT_SENDING`
-- 失败重试最多 1 次（避免重复刷屏）
-
-## 4.2 InterruptManager
-
-职责：
-- 监听用户新消息事件
-- 取消当前发送任务
-- 记录中断点（最后已送达 segment_id）
-
-建议规则：
-- 中断优先级高于发送
-- 丢弃未送达段，不做补发
-
-## 4.3 DeliveredHistoryStore（Redis）
-
-建议键：`chat:{sessionId}:delivered`
-
-建议字段：
-- role（user/assistant/human）
-- content
-- timestamp
-- segment_id（assistant可选）
-- source（bot/human）
-
-只存“已送达”消息，避免上下文污染。
-
-## 4.4 MessageReporter
-
-职责：
-- 异步上报全量消息到中台历史服务
-- 支持重试与死信队列
-
-必须上报：
-- 用户消息
-- 机器人每个已送达段
-- 人工客服消息
-- 模式切换事件（bot->human/human->bot）
-
----
-
-## 5. 请求与响应协议建议
-
-## 5.1 渠道 -> 中台请求
-```json
-{
-  "session_id": "sess_123",
-  "user_message": "孩子五年级，数学不好",

-## 6. 与中台协同的关键约束
-
-1. 渠道侧只认 `segments[]`，不关心中台内部是 agent 还是 flow。
-2. 必须使用“已送达历史”回传，不能用“计划发送历史”。
-3. 打断后立即重发，不等待旧请求自然结束。
-4. 人工模式下继续上报，保证中台记忆与分析完整。
-
----
-
-## 7. 可观测性指标（渠道侧）
-
-建议上报指标：
-- `segment_send_latency_ms`
-- `segment_drop_count`（中断丢弃）
-- `interrupt_count`
-- `resend_request_count`
-- `bot_to_human_switch_count`
-- `history_report_success_rate`
-
-日志关键字段：
-- session_id
-- request_id
-- segment_id
-- mode
-- interrupted_at
-
----
-
-## 8. 分阶段实施建议（渠道侧）
-
-## Phase 1
-- 实现分段发送 + 本地已送达历史
-- 接入中台 `segments` 协议
-
-## Phase 2
-- 打断管理上线（实时取消 + 重新请求）
-- 全量消息上报链路上线
-
-## Phase 3
-- 人工接管状态机完善
-- 失败重试、幂等、死信治理完善
-
----
-
-## 9. 风险与应对
-
-1. 重复发送风险
-- 通过 `segment_id + session_id` 做幂等去重
-
-2. 中断竞态（旧包晚到）
-- 用 `request_id` / `generation_id` 校验，只消费最新响应
-
-3. 历史错乱
-- 仅以“已送达消息”入历史，不以“待发送消息”入历史
-
-4. 上报积压
-- 异步队列 + 批量上报 + 失败重试
-
----
-
-## 10. 最终建议（渠道侧）
-
-- 渠道侧的首要目标不是“更聪明”，而是“更稳定 + 更像人 + 可打断”。
-- 只要分段、打断、历史上报三件事做稳，中台 Agent 的价值会显著放大。

-# AI客服智能体增强改造方案（仅中台侧）
-
-## 1. 改造定位
-
-中台侧承担“智能决策与会话编排核心”角色，负责在不改变渠道发送机制的前提下，输出可被渠道稳定消费的分段回复与可观测信息。
-
-本次文档范围**仅覆盖中台侧**，并以渠道侧协同接口为边界。
-
-### 核心目标
-- 统一中台对外响应为 `segments[]` 协议，支撑渠道侧分段发送与打断重入。
-- 构建“Agent 主链路 + Micro-flow 护栏兜底”的双轨决策。
-- 仅基于“已送达历史”做上下文推理，避免上下文污染。
-- 完整沉淀可观测字段，支持回放、归因与灰度治理。
-
-### 非目标（Out of Scope）
-- 不定义渠道侧发送节奏实现细节（队列、重试、UI 展现）。
-- 不新增渠道侧状态机实现要求（仅声明协同接口语义）。
-- 不扩展 Python 代码级任务与语言实现细节。
-
----
-
-## 2. 中台侧能力边界
-
-## 2.1 中台负责
-1. 接收会话请求并执行策略路由（agent / micro_flow / fixed / transfer）。
-2. 组织工具调用（KB/Intent/Flow/Prompt/Memory）并生成结果。
-3. 返回分段回复 `segments[]` 与追踪信息 `trace`。
-4. 接收并落库全量消息上报（含人工阶段消息与模式切换事件）。
-5. 提供会话模式状态接口（机器人/人工）。
-
-## 2.2 中台不负责
-1. 渠道消息发送调度与本地打断取消逻辑。
-2. 渠道本地“已送达历史”缓存实现。
-3. 渠道端展示层节奏控制。
-
----
-
-## 3. 协同契约（与渠道侧）
-
-## 3.1 请求协议（渠道 -> 中台）
-```json
-{
-  "session_id": "sess_123",
-  "user_message": "孩子五年级，数学不好",
-  "history": [
-    {"role": "user", "content": "你好"},
-    {"role": "assistant", "content": "您好"}
-  ],
-  "interrupted_segments": [
-    {"segment_id": "seg_2", "content": "稍等，我查一下"}
-  ]
-}
-```
-
-约束：
-- `history` 必须是**已送达历史**，不得包含未送达片段。
-- `interrupted_segments` 为可选协同信息，中台可用于上下文修正与日志归因。
-
-## 3.2 响应协议（中台 -> 渠道）
-```json
-{
-  "segments": [
-    {"segment_id": "seg_3", "text": "好的，请问孩子具体是哪个知识点薄弱？", "delay_after": 800},
-    {"segment_id": "seg_4", "text": "比如分数应用题还是几何？", "delay_after": 0}
-  ],
-  "trace": {
-    "mode": "agent",
-    "intent": "course_consult",
-    "tools_used": ["get_knowledge_bases", "recall_memory"]
-  }
-}
-```
-
-约束：
-- 中台必须保证 `segments[]` 可直接消费，不依赖渠道二次改写。
-- `trace.mode` 必须返回，便于渠道侧与观测平台统一归因。
-
----
-
-## 4. 中台核心架构
-
-## 4.1 决策总线
-- `policy_router`：根据意图、风险级别、置信度决定执行模式：
-  - `agent`（默认）
-  - `micro_flow`（高风险/强SOP）
-  - `fixed`（固定答复）
-  - `transfer`（转人工）
-
-## 4.2 Agent 执行层
-- `Agent Orchestrator` 执行 ReAct 循环（思考-行动-观察）。
-- 通过 `Tool Registry` 调用工具（含 MCP 扩展能力）。
-- 输出统一分段结构，受输出护栏二次校验。
-
-## 4.3 微流程护栏层
-仅保留高风险场景的最小流程集：
-- 退款/退费
-- 投诉升级
-- 隐私与敏感承诺
-- 转人工
-
-## 4.4 记忆与元数据层
-- 记忆读取：按 `user_id/session_id` 注入长期与短期上下文。
-- 元数据检索：严格执行 `intent -> target_kbs -> metadata_filter -> vector_search -> rerank`。
-- 标签规范遵循既有方法论（grade/subject/scene/flow_step/intent_type 等）。
-
----
-
-## 5. 中台执行时序
-
-## 5.1 正常对话
-1. 接收渠道请求（含已送达历史）。
-2. `policy_router` 决策模式。
-3. 进入 `agent` 或 `micro_flow`。
-4. 工具调用 + 护栏校验。
-5. 返回 `segments[] + trace`。
-6. 异步写入会话日志与观测事件。
-
-## 5.2 打断重入
-1. 渠道发送中断后发起新请求。
-2. 中台接收新的 `history` 与可选 `interrupted_segments`。
-3. 丢弃旧 generation 的输出影响，仅以最新请求生成结果。
-4. 返回新的 `segments[]`，保证语义连续。
-
-## 5.3 人工接管
-1. 渠道触发模式切换接口，标记 `HUMAN_ACTIVE`。
-2. 中台停用机器人主链路输出。
-3. 持续接收并记录人工消息上报。
-4. 必要时支持 `HUMAN_ACTIVE -> BOT_ACTIVE` 回切。
-
----
-
-## 6. 关键治理与门禁
-
-## 6.1 质量门禁
-- 输出必须可分段消费（结构合法、字段完整）。
-- 高风险场景必须命中 micro-flow，不允许 agent 直出。
-- 低置信度或工具异常必须降级（fixed 或 transfer）。
-
-## 6.2 可观测性字段（必须）
-- `mode`
-- `intent_id/intent`
-- `target_kbs`
-- `applied_metadata_filters`
-- `tool_calls`（参数摘要、耗时、状态）
-- `fallback_reason_code`
-- `guardrail_triggered`
-- `session_id/request_id/generation_id`
-
-## 6.3 关键指标（建议）
-- 响应时延 P50/P95
-- 工具超时率
-- fallback 触发率
-- micro-flow 接管率
-- 误转人工率
-- 无召回率
-
----
-
-## 7. 分阶段落地（仅中台）
-
-## Phase 1：协议与主链路打通
-- 固化 `segments[]` 对外响应协议。
-- 打通 `policy_router + Agent Orchestrator` 最小闭环。
-- 上线基础观测字段。
-
-## Phase 2：护栏与记忆增强
-- 上线高风险 micro-flow 最小集。
-- 接入记忆读写与 metadata 过滤检索全链路。
-- 完善降级与回退策略。
-
-## Phase 3：稳定性与治理
-- 完善 generation 级并发与乱序治理。
-- 强化工具治理（超时、重试、熔断、错误映射）。
-- 建立灰度策略与回滚开关。
-
----
-
-## 8. 主要风险与应对
-
-1. 打断竞态导致旧响应污染
-- 应对：按 `generation_id/request_id` 只认最新请求结果。
-
-2. 工具调用抖动影响时延
-- 应对：工具超时上限 + 快速降级 + 结果摘要缓存（可选）。
-
-3. 元数据质量不一致导致召回偏差
-- 应对：统一 metadata 枚举、入库校验、周期巡检。
-
-4. 智能体自由度过高引发合规风险
-- 应对：policy_router 前置约束 + 输出护栏 + micro-flow 强接管。
-
----
-
-## 9. 最终结论
-
-本方案坚持“仅中台侧改造”：
-- 以统一分段协议承接渠道可打断发送能力。
-- 以 Agent 主链路提升效果，以 Micro-flow 护栏保证可控。
-- 以观测与治理机制保障可回放、可归因、可灰度演进。
-
-在不扩展渠道实现细节与不引入语言实现绑定的前提下，可支撑中台能力平滑升级。

--- 新增字段：field_roles
-ALTER TABLE metadata_field_definitions 
-ADD COLUMN field_roles JSONB DEFAULT '[]'::jsonb;
-

-### 5.2 按角色过滤视图
-
-**新增过滤器**：在元数据字段列表页面增加角色过滤下拉框
-
-```vue
-<template>
-  <div class="filter-bar">
-    <el-select 
-      v-model="selectedRole" 
-      placeholder="按角色过滤"
-      clearable
-      @change="handleRoleFilter"

-        :key="role.value"
-        :label="role.label"
-        :value="role.value"
-      />
-    </el-select>
-  </div>
-</template>
-```

-## 6. 缓存策略
-
-### 6.1 缓存设计
-
-```python
-class FieldRoleCache:
-    """字段角色缓存"""
-    
-    CACHE_KEY_PREFIX = "field_roles"
-    CACHE_TTL = 300  # 5分钟
-    
-    async def get_fields_by_role(
-        self,
-        tenant_id: str,
-        role: FieldRole,
-    ) -> list[MetadataFieldDefinition]:
-        cache_key = f"{self.CACHE_KEY_PREFIX}:{tenant_id}:{role}"
-        
-        # 尝试从缓存获取
-        cached = await self._redis.get(cache_key)
-        if cached:
-            return self._deserialize(cached)
-        
-        # 从数据库查询
-        fields = await self._db_query(tenant_id, role)
-        
-        # 写入缓存
-        await self._redis.setex(
-            cache_key,
-            self.CACHE_TTL,
-            self._serialize(fields),
-        )
-        
-        return fields
-    
-    async def invalidate(self, tenant_id: str):
-        """失效租户所有角色缓存"""
-        pattern = f"{self.CACHE_KEY_PREFIX}:{tenant_id}:*"
-        keys = await self._redis.keys(pattern)
-        if keys:
-            await self._redis.delete(*keys)
-```
-
-### 6.2 缓存失效策略
-
-- 字段创建/更新/删除时失效该租户所有角色缓存
-- 槽位定义变更时失效相关角色缓存
-
----
-
-## 7. 异常处理
-
-### 7.1 错误码定义
-
-| 错误码 | 说明 | HTTP 状态码 |
-|-------|------|------------|
-| `INVALID_ROLE` | 无效的角色参数 | 400 |
-| `FIELD_KEY_EXISTS` | field_key 已存在 | 409 |
-| `SLOT_KEY_EXISTS` | slot_key 已存在 | 409 |
-| `LINKED_FIELD_NOT_FOUND` | 关联字段不存在 | 404 |
-
-### 7.2 异常处理示例
-
-```python
-class InvalidRoleError(Exception):
-    """无效角色异常"""
-    def __init__(self, role: str):
-        self.role = role
-        self.valid_roles = [r.value for r in FieldRole]
-        super().__init__(
-            f"Invalid role '{role}'. Valid roles are: {', '.join(self.valid_roles)}"
-        )
-```
-
----
-
-## 8. 测试策略
-
-### 8.1 单元测试
-
-- `RoleBasedFieldProvider` 按角色查询测试
-- `FieldRoleCache` 缓存读写测试
-- 字段角色校验测试
-
-### 8.2 集成测试
-
-- API 端点测试（CRUD + 按角色查询）
-- 工具协同改造测试（验证各工具只消费对应角色字段）
-
-### 8.3 契约测试
-
-- OpenAPI Schema 校验
-- 响应结构验证
-
----
-
-## 9. 迁移与部署
-
-### 9.1 数据库迁移
-
-```sql
--- 1. 新增 field_roles 字段
-ALTER TABLE metadata_field_definitions 
-ADD COLUMN field_roles JSONB DEFAULT '[]'::jsonb;
-
--- 2. 创建索引
-CREATE INDEX idx_metadata_field_definitions_roles 
-ON metadata_field_definitions USING GIN (field_roles);
-
--- 3. 创建 slot_definitions 表
-CREATE TABLE slot_definitions (
-    -- ... 见 2.2 节
-);
-
--- 4. 初始化现有字段的默认角色（可选）
--- 根据 is_filterable 推断 resource_filter 角色
-UPDATE metadata_field_definitions 
-SET field_roles = '["resource_filter"]'::jsonb
-WHERE is_filterable = true AND status = 'active';
-```
-
-### 9.2 部署顺序
-
-1. 执行数据库迁移脚本
-2. 部署后端服务（向后兼容，field_roles 可为空）
-3. 部署前端页面
-4. 配置字段角色
-
----
-
-## 10. 监控与观测
-
-### 10.1 关键指标
-
-| 指标名 | 说明 |
-|-------|------|
-| `field_role_query_count` | 按角色查询次数 |
-| `field_role_query_latency` | 按角色查询延迟 |
-| `field_role_cache_hit_rate` | 角色缓存命中率 |
-| `tool_field_consumption` | 工具字段消费统计 |
-
-### 10.2 日志字段
-
-```json
-{
-  "event": "field_role_query",
-  "tenant_id": "xxx",
-  "role": "resource_filter",
-  "field_count": 5,
-  "duration_ms": 12,
-  "cache_hit": true
-}

----
-
-# 元数据职责分层优化（MRS）
-
-## 1. 背景与目标
-
-### 1.1 背景
-
-当前系统中元数据字段承担了多种隐式职责，导致以下问题：
-
-1. **职责混淆**：同一字段（如 `grade`）同时用于资源过滤、运行时槽位、提示词变量和路由信号，但系统无法区分其具体用途
-2. **工具耦合**：`kb_search_dynamic`、`memory_recall`、`intent_hint`、`high_risk_check` 等工具全量消费元数据字段，无法按需筛选
-3. **槽位语义模糊**：槽位与元数据字段概念混淆，缺少独立的槽位定义模型
-4. **配置不可视**：管理端无法按职责视角查看和配置字段
-
-### 1.2 目标
-
-- 为元数据字段引入显式的 `field_roles` 职责分层
-- 建立独立的槽位定义模型，与元数据字段解耦但可复用
-- 改造工具链按职责角色消费字段，实现精准消费
-- 提供管理端按角色配置和查看的能力
-
-### 1.3 非目标（Out of Scope）
-
-- 不处理历史数据迁移，允许删除重建配置
-- 不新增元数据字段类型（保持 string/number/boolean/enum/array_enum）
-- 不替换向量引擎或 LLM 供应商
-- 不覆盖渠道端具体实现
-
-## 2. 模块边界（Scope）
-
-- 覆盖：元数据字段职责分层、槽位定义模型、工具协同改造、管理端配置能力
-- 不覆盖：历史数据迁移、向量引擎替换、模型切换、渠道端实现
-
-## 3. 依赖盘点（Dependencies）
-
-- `metadata-governance` 模块：元数据字段定义基础能力
-- `intent-driven-mid-platform` 模块：中台运行时工具链
-- `ai-service-admin` 前端：管理端配置界面
-
-## 4. 用户故事（User Stories）
-
-- [US-MRS-01] 作为系统架构师，我希望元数据字段有明确的职责角色标记，以便工具能按需消费。
-- [US-MRS-02] 作为后端开发者，我希望通过接口按角色查询字段定义，以便精准获取所需字段。
-- [US-MRS-03] 作为运营配置人员，我希望在管理端按角色过滤查看字段，以便快速定位配置。
-- [US-MRS-04] 作为对话系统开发者，我希望槽位有独立的定义模型，以便管理运行时槽位语义。
-- [US-MRS-05] 作为工具开发者，我希望 `kb_search_dynamic` 只消费资源过滤角色字段，以便避免无关字段干扰。
-- [US-MRS-06] 作为工具开发者，我希望 `memory_recall` 只消费槽位角色字段，以便精准管理对话槽位。
-- [US-MRS-07] 作为工具开发者，我希望 `intent_hint/high_risk_check` 只消费路由信号角色字段，以便精准路由决策。
-- [US-MRS-08] 作为提示词工程师，我希望 prompt 渲染只消费提示词变量角色字段，以便控制注入范围。
-
-## 5. 验收标准（Acceptance Criteria, EARS）
-
-### 5.1 字段职责分层
-
-- [AC-MRS-01] WHEN 管理员创建或编辑元数据字段 THEN 系统 SHALL 支持 `field_roles` 多选配置，可选值为 `resource_filter`、`slot`、`prompt_var`、`routing_signal`。
-- [AC-MRS-02] WHEN 保存字段定义时 `field_roles` 为空 THEN 系统 SHALL 允许保存（默认无职责）。
-- [AC-MRS-03] WHEN 字段定义包含多个 `field_roles` THEN 系统 SHALL 正确存储并返回所有角色。
-
-### 5.2 分层视图能力
-
-- [AC-MRS-04] WHEN 调用 `GET /admin/metadata-schemas/by-role?role=resource_filter` THEN 系统 SHALL 返回所有 `field_roles` 包含 `resource_filter` 的活跃字段定义。
-- [AC-MRS-05] WHEN 调用按角色查询接口且角色参数无效 THEN 系统 SHALL 返回 400 错误并提示有效角色列表。
-- [AC-MRS-06] WHEN 管理端请求字段列表 THEN 系统 SHALL 支持按 `field_roles` 过滤展示。
-
-### 5.3 槽位模型
-
-- [AC-MRS-07] WHEN 管理员创建槽位定义 THEN 系统 SHALL 支持 `slot_key`、`type`、`required`、`extract_strategy`、`validation_rule`、`ask_back_prompt` 属性配置。
-- [AC-MRS-08] WHEN 槽位定义的 `slot_key` 与已有元数据字段 `field_key` 相同 THEN 系统 SHALL 允许创建并建立关联关系。
-- [AC-MRS-09] WHEN 运行时读取槽位值 THEN 系统 SHALL 返回 `source`（来源）、`confidence`（置信度）、`updated_at`（更新时间）属性。
-- [AC-MRS-10] WHEN 调用 `GET /mid/slots/by-role?role=slot` THEN 系统 SHALL 返回所有 `field_roles` 包含 `slot` 的字段定义及关联的槽位定义。
-
-### 5.4 工具协同改造
-
-- [AC-MRS-11] WHEN `kb_search_dynamic` 构建过滤器 THEN 系统 SHALL 仅使用 `field_roles` 包含 `resource_filter` 的字段。
-- [AC-MRS-12] WHEN `memory_recall` 召回槽位 THEN 系统 SHALL 仅使用 `field_roles` 包含 `slot` 的字段。
-- [AC-MRS-13] WHEN `intent_hint` 或 `high_risk_check` 进行路由判断 THEN 系统 SHALL 仅使用 `field_roles` 包含 `routing_signal` 的字段。
-- [AC-MRS-14] WHEN 模板引擎渲染 prompt THEN 系统 SHALL 仅使用 `field_roles` 包含 `prompt_var` 的字段。
-
-### 5.5 管理端可配置能力
-
-- [AC-MRS-15] WHEN 管理员在元数据字段编辑界面 THEN 系统 SHALL 显示 `field_roles` 多选配置组件。
-- [AC-MRS-16] WHEN 管理员删除字段或槽位定义 THEN 系统 SHALL 允许删除且无需考虑历史数据兼容性。

-      - node_entered（分层/危机/方案/报价/加微）
-      - objection_type（价格/时间/效果/信任）
-      - conversion_step（接受报价、同意听直播、完成加微）
-
-  - 提示词约束项：
-    - 角色约束：
-      - 以课程顾问身份进行诊断式沟通，先分层再推荐，不直接硬推销。
-    - 对话策略约束：
-      - 必须先确认年级，再给课程针对性说明。
-      - 必须至少询问一个薄弱点或考试表现，再进入方案介绍。
-      - 报价后必须发起“价格可接受度确认”。
-    - 风格约束：
-      - 语气专业、关怀、不过度夸张。
-      - 用“问题-方案-结果-行动”结构表达。
-    - 合规约束：
-      - 对“清北老师主讲”“达成深度合作”等表述增加可校验开关，默认不做绝对化承诺。
-      - 禁止承诺“保证提分/保证结果”。
-    - 工具/事实优先级：
-      - 优先读取课程事实库（价格、节数、上课形式、回放、服务）再组织话术。
-      - 未命中事实时使用保守表述，并引导人工确认。

-# 中台智能体运行时加固（MARH）设计文档
-
-## 1. 设计目标
-
-围绕 AC-MARH-01~12，构建中台运行时加固层，确保输出可控、打断可消费、检索可依赖、时延可治理、节奏可调优。
-
----
-
-## 2. 架构改造点
-
-## 2.1 对话主链路增强
-在 `respond` 主流程增加以下阶段：
-1. `interrupt_context_enricher`：消费 `interrupted_segments`
-2. `kb_default_tool_stage`：Agent 默认检索工具尝试
-3. `output_guardrail_stage`：输出前强制过滤
-4. `segment_humanizer`：语义+长度分段与 delay 计算
-5. `runtime_observer`：补齐 trace 与 metrics
-
-## 2.2 超时统一治理
-- ReAct 最大循环：3~5
-- 单工具超时：<=2000ms
-- 全链路超时：<=8000ms
-- 超时均落 `fallback_reason_code`
-
----
-
-## 3. 关键流程
-
-## 3.1 正常响应流程
-1. 收到请求并校验已送达历史
-2. 若存在中断片段则做语义去重标记
-3. policy_router 决策
-4. Agent 模式默认调用 KB 工具（可降级）
-5. 生成候选文本
-6. 输出护栏强制过滤
-7. 分段拟人策略生成 `segments[]`
-8. 输出 trace（guardrail/interrupt/kb_hit/timeouts/segment_stats）
-
-## 3.2 打断重入流程
-1. 新请求带 `interrupted_segments`
-2. 重规划时避开被打断语义
-3. 若中断信息异常则兜底继续
-
----
-
-## 4. 数据结构与字段补充
-
-新增或强化 trace 字段：
-- `guardrail_triggered`
-- `guardrail_rule_id`
-- `interrupt_consumed`
-- `kb_tool_called`
-- `kb_hit`
-- `segment_stats`
-- `timeout_profile`
-
----
-
-## 5. 组件职责
-
-- `OutputGuardrailExecutor`
-  - 强制执行输出过滤
-  - 返回 blocked/filtered_text/rule_id
-
-- `InterruptContextEnricher`
-  - 将中断片段转成重规划上下文
-  - 提供异常兜底
-
-- `DefaultKbToolRunner`
-  - Agent 默认 KB 检索
-  - 失败时返回降级信号
-
-- `SegmentHumanizer`
-  - 文本分段与 delay 生成
-  - 支持租户覆盖配置
-
-- `RuntimeObserver`
-  - 汇总 trace 与 metrics
-
----
-
-## 6. 与 AC 映射
-
-- AC-MARH-01/02：`OutputGuardrailExecutor`
-- AC-MARH-03/04：`InterruptContextEnricher`
-- AC-MARH-05/06：`DefaultKbToolRunner`
-- AC-MARH-07/08/09：`TimeoutGovernor + Orchestrator`
-- AC-MARH-10/11：`SegmentHumanizer`
-- AC-MARH-12：`RuntimeObserver`
