fix: P0-1 RateLimiter并发写安全 + P0-2工单操作错误码区分 + P1 rows.Close修复
P0-1 (limits.go): Allow()方法改为全程使用写锁保护counters map读写，避免RLock写入时的data race P0-2 (ticket_workflow.go+ticket_handler.go): Assign/Resolve/Close操作先查询ticket存在性和状态，返回明确的CS_TICKET_4001/CS_TKT_4002/CS_TICKET_4092/CS_TICKET_4093错误码，handler根据错误前缀路由HTTP状态码 P1-1 (ticket_store.go): 移除GetStats中3处手动rows.Close()，只保留defer Close()

# 立交桥项目规则
|
||||
|
||||
## 项目定位
|
||||
|
||||
立交桥处于从 Demo 向生产级产品重构的阶段。这里的默认标准不是“功能能跑”，而是“能长期稳定上线、可维护、可观测、可扩展、可审计”。
|
||||
|
||||
任何改动都应优先服务于生产质量提升：稳定性、性能、安全性、可维护性、可验证性。演示型写法、一次性修补和无法长期维护的捷径都应谨慎对待。
|
||||
|
||||
## 根级工作原则
|
||||
|
||||
1. 生产主链路优先。
|
||||
只要一个能力没有接进真实运行主链路、没有验证关键路径、没有覆盖错误场景，就不要轻易定义为“已完成”。
|
||||
|
||||
2. 先澄清影响面，再改。
|
||||
立交桥包含多个子模块。修改前先识别影响的是哪个边界：`gateway/`、`internal/`、`platform-token-runtime/`、`supply-api/`、`sql/`、`scripts/`、`tests/`。
|
||||
|
||||
3. 质量闭环优先于代码数量。
|
||||
优先补齐验证、接口契约、异常处理、日志与健康检查，而不是仅追求功能增量。
|
||||
|
||||
4. 最小必要改动。
|
||||
生产级重构要控制变更半径。优先做局部可验证优化，而不是大范围重写。
|
||||
|
||||
## 模块协作规则
|
||||
|
||||
- 根目录 `AGENTS.md` 负责全局工程目标、质量标准和交付口径。
|
||||
- 如果某个子目录存在更具体的上下文文件，进入该子目录后必须叠加遵守。
|
||||
- 当前已知局部规则文件：
|
||||
- [CLAUDE.md](/home/long/project/立交桥/supply-api/CLAUDE.md)
|
||||
|
||||
尤其在 `supply-api/` 下工作时，必须同时遵守该文件中的 Go、审计、健康检查、错误处理与接口规范。
|
||||
|
||||
## 默认工作流
|
||||
|
||||
### 1. 接任务先判断类型
|
||||
|
||||
- 缺陷修复：先复现，再定位根因，再补验证
|
||||
- 重构优化：先确定是否触及公共契约、数据库、接口行为
|
||||
- 新能力开发：先定义边界、非目标、失败处理和验证策略
|
||||
- 文档完善：必须围绕真实运行主链路组织，而不是只写静态介绍
|
||||
|
||||
### 2. 对每项改动至少回答
|
||||
|
||||
- 改的是什么问题
|
||||
- 根因是什么
|
||||
- 影响哪些模块和接口
|
||||
- 有哪些风险和回归点
|
||||
- 如何验证主路径与失败路径
|
||||
|
||||
## 质量门槛
|
||||
|
||||
### 稳定性
|
||||
|
||||
- 关键路径要有明确错误处理
|
||||
- 不能依赖静默失败或“日志里写一下就算处理”
|
||||
- 外部依赖异常时，必须明确 fail-open 或 fail-closed 策略
|
||||
|
||||
### 性能
|
||||
|
||||
- 涉及核心路径时，关注响应时间、并发竞争、数据库访问次数、缓存命中和超时边界
|
||||
- 性能优化必须建立在测量或明确瓶颈判断上，不做拍脑袋优化
|
||||
|
||||
### 安全
|
||||
|
||||
- 不暴露内部实现细节、敏感数据、密钥和隐私字段
|
||||
- 审计、鉴权、幂等、配额、状态机类改动要格外谨慎
|
||||
- 高风险默认拒绝“假成功”
|
||||
|
||||
### 可维护性
|
||||
|
||||
- 命名、接口、日志、错误码、迁移脚本要保持一致
|
||||
- 不引入一次性“补丁风格”代码路径
|
||||
- 复杂逻辑必须让下一位维护者能读懂
|
||||
|
||||
## 测试与验证
|
||||
|
||||
### 完成标准默认包含
|
||||
|
||||
- 至少一条主路径验证
|
||||
- 至少一条关键失败路径验证
|
||||
- 如涉及公共接口、存储、并发、审计、权限或计费，必须提高验证强度
|
||||
|
||||
### 不算完成的情况
|
||||
|
||||
- 代码写了，但主链路未接入
|
||||
- 只过了编译，没有跑关键验证
|
||||
- 只测了 happy path，没有测约束/异常/冲突场景
|
||||
- 只写了文档或注释，没有修复行为本身
|
||||
|
||||
## 目录级关注点
|
||||
|
||||
- `gateway/`：协议边界、鉴权、路由、可观测性、退化策略
|
||||
- `internal/`：领域边界、内部服务、公共库稳定性
|
||||
- `platform-token-runtime/`：运行时状态、令牌/资源约束、异常恢复
|
||||
- `supply-api/`：遵守子目录局部规则，重视契约和审计
|
||||
- `sql/`：迁移安全、兼容性、回滚路径
|
||||
- `scripts/`：部署/运维脚本幂等性与可重复执行
|
||||
- `tests/`：优先覆盖真实风险点，不追求无意义覆盖率
|
||||
|
||||
## 文档要求
|
||||
|
||||
- 记录真实系统行为，而不是理想化状态
|
||||
- 部署、排障、接口、重构说明应围绕实际操作路径组织
|
||||
- 对未完成能力要明确标注状态，避免误导为“已经上线可用”
|
||||
|
||||
## 禁止事项
|
||||
|
||||
- 不要把 Demo 级实现包装成生产完成
|
||||
- 不要用“大概可用”替代验证
|
||||
- 不要在没有迁移与回归考虑时随意调整接口或数据结构
|
||||
- 不要为了短期推进牺牲长期可维护性，除非明确标注为临时方案

# 立交桥 V1 产品重设计草案
|
||||
|
||||
- 日期：2026-04-24
|
||||
- 状态：讨论中草案
|
||||
- 当前范围：已固化产品定位、协议策略、MVP 兼容边界；核心对象模型与信息架构为待确认草案
|
||||
|
||||
## 1. 产品定位与第一性目标
|
||||
|
||||
新立交桥不再定义为“可自部署的兼容网关程序”，而是定义为一个**面向中小企业终端客户的 AI 接入 SaaS**。其核心竞争对象不是底层模型厂商，而是 `newapi`、`sub2api` 这一类“可以快速部署运营但产品完成度不足”的兼容网关产品。对比这些竞品，立交桥 v1 不追求“支持最多功能”，而是明确以三类差异化为主：
|
||||
|
||||
1. 更强的协议兼容与模型接入覆盖。
|
||||
2. 更好的用户端体验，降低首次接入和日常使用摩擦。
|
||||
3. 更强的管理端运维能力，尤其是可观测、诊断、告警和智能运维能力。
|
||||
|
||||
v1 的首要价值不是控制台有多复杂，而是用户在**5 分钟内把现有客户端的 Base URL 改掉后直接跑通**。因此，产品增长路径明确选择“开发者主导的自助式增长”，而不是传统企业采购路径。用户先以个人身份注册、充值、创建 Key、完成首次调用成功，再邀请团队成员进入工作区。工作区仍然是计费与治理主体，但首单和首次激活由开发者完成。
|
||||
|
||||
商业模式选择为**预充值余额 + 按调用量扣费**。这是因为 v1 需要同时支持多上游、多模型、动态成本与按能力矩阵定价。如果一开始就做固定套餐，会把后续模型接入、成本透传和账单解释能力锁死。账户治理模型采用“**工作区是一等主体，个人是登录身份**”的结构：成员、API Key、余额、账单、模型权限、审计和策略都挂在工作区下。
|
||||
|
||||
## 2. 协议策略、兼容承诺与模型语义
|
||||
|
||||
立交桥 v1 明确采用**双协议核心产品**策略：`OpenAI` 与 `Anthropic` 都进入 v1 的核心承诺面，不再是“OpenAI 主轴 + Anthropic 辅助适配”。但它也不是简单并排放两套网关，而是“**外部双协议，内部单核心**”：对外保留两套原生协议体验，对内统一收口到一套 canonical 模型目录、能力矩阵、路由策略、额度计量、账务、审计和运维真相层。
|
||||
|
||||
在 OpenAI 面，v1 的强兼容主链路至少包括：
|
||||
|
||||
- `GET /v1/models`
|
||||
- `POST /v1/chat/completions`
|
||||
|
||||
在 Anthropic 面，v1 的核心兼容主链路至少包括：
|
||||
|
||||
- `POST /v1/messages`
|
||||
- 与模型发现、模型映射、错误语义、SDK 行为相关的核心配套能力
|
||||
|
||||
这两个协议面都进入 v1 核心承诺，且都要覆盖高频高级能力，而不只是最低配文本调用。当前已经确认的能力范围包括：
|
||||
|
||||
- 非流式文本输出
|
||||
- 流式输出
|
||||
- tool calling / tool use
|
||||
- 多模态输入
|
||||
|
||||
但平台**不对所有模型做一刀切承诺**。能力承诺必须按模型能力矩阵显式声明，避免出现“平台说支持，但具体模型一调就报错”的竞品式体验。为此，模型不能再被设计成一个普通字符串，而必须是一个产品契约对象。模型命名采用**双层命名**：
|
||||
|
||||
1. 对外保留兼容名和迁移别名，支持用户“改 Base URL 就能跑”。
|
||||
2. 对内维护 canonical model ID、上游映射、价格、能力矩阵、可用区间和路由策略。
|
||||
|
||||
`model` 字段采用**双模式语义**：
|
||||
|
||||
1. 默认模式下，用户使用兼容名或稳定公共名，优先保证迁移友好。
|
||||
2. 高级模式下，用户可以显式指定上游模型、模型别名或受控路由策略。
|
||||
|
||||
## 3. 核心对象模型与信息架构（待确认）
|
||||
|
||||
为了同时支撑双协议、双层模型命名、工作区计费和后续智能运维，v1 的核心对象建议收敛为以下几类：
|
||||
|
||||
1. `Identity`
|
||||
表示登录用户，只负责认证、登录会话和成员关系，不直接承载账务。
|
||||
2. `Workspace`
|
||||
是一等业务主体，承载余额、充值、账单、成员、API Key、默认路由策略、模型权限和审计边界。
|
||||
3. `Credential`
|
||||
包括工作区下的 API Key、可能的子 Key、用途标签、状态、权限范围和调用限制。
|
||||
4. `Model Catalog`
|
||||
平台维护的模型目录对象，不只是模型列表，而是“外部名 - canonical ID - 上游映射 - 能力矩阵 - 价格 - 可用状态”的统一真相层。
|
||||
5. `Provider / Upstream`
|
||||
表示 OpenAI、Azure OpenAI、Anthropic、DeepSeek、阿里百炼、火山方舟等接入源，以及它们的区域、凭据、速率限制和健康状态。
|
||||
6. `Route Policy`
|
||||
表示当用户请求某个模型名时，平台如何解析、选择上游、失败时如何回退、何时熔断，以及是否允许智能切换。
|
||||
7. `Usage Ledger`
|
||||
表示调用级计量事实，记录协议面、模型名、解析后的 canonical model、上游、token/图片/工具调用等费用相关事实。
|
||||
8. `Billing Record`
|
||||
表示对工作区可解释的账务结果，包括预扣、结算、退款、调整和对账状态。
|
||||
9. `Audit Event`
|
||||
记录认证、Key 变更、充值、模型策略调整、异常调用、运维处置和权限操作。
|
||||
10. `Ops Incident`
|
||||
面向管理端与智能运维，记录上游故障、模型异常、路由抖动、错误突增和自动化处置结果。
|
||||
|
||||
基于这些对象，v1 的控制台信息架构建议按“用户完成任务的顺序”组织，而不是按内部模块组织。控制台一级导航建议优先有：
|
||||
|
||||
- 概览
|
||||
- API Keys
|
||||
- 模型目录
|
||||
- 在线调试
|
||||
- 用量与账单
|
||||
- 路由与策略
|
||||
- 运维与诊断
|
||||
- 成员与工作区设置
|
||||
|
||||
这样设计的核心原因是：用户首先要完成首次接入成功，其次才是理解模型能力差异，再之后才是成本、策略和运维。控制台必须服务这一条真实路径，而不是暴露内部模块名。
|
||||
|
||||
## 4. 当前已确认结论
|
||||
|
||||
截至本草案版本，以下决定已经确认：
|
||||
|
||||
1. 新立交桥是面向中小企业终端客户的 AI 接入 SaaS。
|
||||
2. v1 采用开发者主导的自助式增长路径。
|
||||
3. 工作区是一等业务与计费主体。
|
||||
4. 商业模式是预充值余额 + 按调用量扣费。
|
||||
5. v1 同时把 OpenAI 与 Anthropic 纳入核心承诺面。
|
||||
6. OpenAI 面至少强兼容 `GET /v1/models` 与 `POST /v1/chat/completions`。
|
||||
7. Anthropic 面提升到接近 OpenAI 同级优先级，纳入 v1 核心能力承诺。
|
||||
8. 高级能力范围包括流式、tool calling / tool use、多模态输入。
|
||||
9. 平台必须按模型能力矩阵显式承诺，而不是统一口号式承诺。
|
||||
10. 模型采用双层命名，对外兼容名，对内 canonical model ID。
|
||||
11. `model` 字段采用默认兼容名 + 高级显式指定的双模式语义。
|
||||
|
||||
## 5. 下一步待确认主题
|
||||
|
||||
后续设计需要继续确认至少以下几个主题：
|
||||
|
||||
1. OpenAI 面与 Anthropic 面的能力对等边界，到底哪些算 v1 强承诺，哪些算 v1.1。
|
||||
2. 模型目录与能力矩阵如何对外展示，是否允许用户自定义别名。
|
||||
3. 路由策略是“默认稳态优先”还是“默认智能优选优先”。
|
||||
4. 用户端控制台首页与首次接入流的具体结构。
|
||||
5. 管理端智能运维的 MVP 边界，到底做告警与诊断，还是直接做自动修复。

# Bridge 项目整体完全重构方案 v1.0
|
||||
|
||||
> **项目**: 立交桥 / Bridge Gateway
|
||||
> **主代码库**: `/home/long/project/立交桥/`
|
||||
> **漂移目录 A**: `/home/long/hermes-agent/bridge/` (规划/前端/部署版)
|
||||
> **漂移目录 B**: `/home/long/hermes-agent-official/bridge/backend/` (精简架构蓝本)
|
||||
> **编制日期**: 2026-04-26
|
||||
> **状态**: 待执行
|
||||
|
||||

|
||||
|
||||
## 一、现状诊断
|
||||
|
||||
### 1.1 三个代码库关系
|
||||
|
||||
```
|
||||
主项目 (立交桥) 漂移目录 A 漂移目录 B
|
||||
┌────────────────────┐ ┌────────────────────┐ ┌──────────────────┐
|
||||
│ gateway/ │ │ docs/plans/ │ │ internal/ │
|
||||
│ supply-api/ │ │ web/apps/ │ │ api/gateway/ │
|
||||
│ platform-token-runtime/ │ │ docker-compose.yml │ │ route/ │
|
||||
│ review/ (大量报告) │ │ backend/ (嵌在官方仓)│ │ service/ │
|
||||
│ sql/ │ │ │ │ upstream/ │
|
||||
└────────────────────┘ └────────────────────┘ └──────────────────┘
|
||||
→ 实际生产代码 → 规划文档+前端+ → 目标架构蓝图
|
||||
部署配置
|
||||
```
|
||||
|
||||
- **主项目**：唯一能够真实启动、测试、落库的代码库。但缺陷严重，前端缺失。
|
||||
- **A目录**：包含完整产品规格、技术架构、实施计划，以及 Next.js 前端设计（admin-console + user-console）。但 `backend/` 是 `hermes-agent` 官方仓库的子目录，非独立模块。
|
||||
- **B目录**：精简的独立 Go 模块（约 1,085 行），采用更干净的分层架构（api → service → upstream → route），是理想的后端架构蓝图。
|
||||
|
||||
### 1.2 主项目关键缺陷
|
||||
|
||||
#### P0 阻塞上线（4个待修复）
|
||||
|
||||
| ID | 模块 | 问题 | 工时 | 状态 |
|
||||
|----|------|------|------|------|
|
||||
| P0-3 | token-runtime | Refresh TTL 不持久化，仅修改内存未调用 store.Save() | 1h | ⚪ 待修 |
|
||||
| P0-4 | token-runtime | 并发写 Map 非线程安全，Save 方法在 mutex 外写 map | 1h | ⚪ 待修 |
|
||||
| P0-5 | token-runtime | `/v1/audit-events` 端点无鉴权可直接查询 | 1h | ⚪ 待修 |
|
||||
| P0-1/2 | gateway | 硬编码密钥/宽松 CORS 仅在 bootstrap 中添加验证，未根除默认值 | 1h | ⚪ 待彻底修复 |
|
||||
|
||||
#### P1 强烈建议（6个待修复）
|
||||
|
||||
| ID | 模块 | 问题 | 工时 | 状态 |
|
||||
|----|------|------|------|------|
|
||||
| P1-1 | supply-api | KMS 使用 SHA-256(concat) 简单哈希派生，固定盐值 | 2h | ⚪ 待修 |
|
||||
| P1-2 | supply-api | JWT 空 alg 时回退到 HS256，可能签名绕过 | 1h | ⚪ 待修 |
|
||||
| P1-3 | supply-api | adapter 层测试覆盖率 **0%** | 4h | ⚪ 待修 |
|
||||
| P1-4 | supply-api | repository 层覆盖率 **3.1%** | 8h | ⚪ 待修 |
|
||||
| P1-5 | gateway | TrustedProxies 未设置，反向代理环境下始终用 RemoteAddr | 1h | ⚪ 待修 |
|
||||
| P1-6 | gateway | 请求 ID 直接信任用户输入，日志注入风险 | 0.5h | ⚪ 待修 |
|
||||
| P1-7 | gateway | 内部错误信息直接暴露给客户端 | 1h | ⚪ 待修 |
|
||||
|
||||
#### 真实环境验证确定性缺陷（6个）
|
||||
|
||||
| 模块 | 问题 |
|
||||
|------|------|
|
||||
| token-runtime | PostgreSQL 刷新/撤销路径存在缺陷 |
|
||||
| supply-api | 幂等锁写入路径存在缺陷 |
|
||||
| supply-api | 套餐创建 SQL 存在问题 |
|
||||
| IAM | 初始化 DDL 存在问题 |
|
||||
| IAM | DB-backed 查询空值扫描 |
|
||||
| 全局 | audit_events 表结构与审计仓储实现不一致 |
|
||||
|
||||
### 1.3 架构和工程问题
|
||||
|
||||
1. **代码分散**：三个目录各自为政，规划、实现、部署不在同一代码库。
|
||||
2. **前端缺失**：主项目无前端源码，A 目录有前端设计但未与后端对接。
|
||||
3. **架构不一致**：三个服务的包结构、错误处理、日志规范、配置管理各有差异。
|
||||
4. **测试薄弱**：adapter 0%、repository 3.1%、多个关键路径无覆盖。
|
||||
5. **CI 缺失**：无持续集成门禁，缺陷发现和修复趁于被动。
|
||||
6. **配置管理混乱**：各服务配置格式、加载方式不统一，敏感配置缺乏加密保护。
|
||||
|
||||
---
|
||||
|
||||
## 二、重构目标
|
||||
|
||||
### 2.1 总体目标
|
||||
|
||||
将分散在三个目录中的 Bridge 项目合并为一个**统一的、生产级的、前后端完整的** 单代码库。
|
||||
|
||||
### 2.2 分层目标
|
||||
|
||||
| 维度 | 目标 | 验收标准 |
|
||||
|------|------|---------|
|
||||
| 安全 | P0 + P1 完全清零 | Bandit 高危+中危为 0，安全测试通过 |
|
||||
| 稳定性 | 核心路径无确定性缺陷 | 真实环境验证报告中所有确定性缺陷修复 |
|
||||
| 可观测性 | 结构化日志 + 健康检查 + 指标 | 三套服务统一日志格式，/健康端点可用 |
|
||||
| 测试 | 关键路径覆盖 | adapter → 80%、repository → 70%、domain → 70% |
|
||||
| 架构 | 三服务统一风格 | 包结构、错误码、日志、配置一致 |
|
||||
| 产品 | 前后端完整对接 | 运营后台 + 用户控制台可启动、可登录、可操作 |
|
||||
| 部署 | 一键部署 | `docker compose up -d` 可启动全部服务 |
|
||||
|
||||
---
|
||||
|
||||
## 三、合并策略
|
||||
|
||||
### 3.1 代码库结构重组
|
||||
|
||||
```
|

```
|
||||
|
||||
### 3.2 合并原则
|
||||
|
||||
| 来源 | 处理方式 | 说明 |
|
||||
|------|---------|------|
|
||||
| 主项目后端代码 | **作为基线保留** | 唯一能够真实启动、落库、通过部分测试的实现 |
|
||||
| A 目录 docs/plans | **合并到 docs/** | 产品规格、架构设计、运维文档是现有资产，需与代码对齐 |
|
||||
| A 目录 web/ | **合并到 web/** | 前端设计已完整，需与后端 API 对接 |
|
||||
| A 目录 docker-compose.yml | **合并为根级** | 整合三套后端服务 + 前端 + DB + Redis + Nginx |
|
||||
| B 目录 internal/ | **架构参考 + 部分合并** | B 的分层更干净（api→service→upstream→route），作为架构改进目标 |
|
||||
| B 目录 crypto/ | **合并到 shared/pkg/crypto/** | B 的 AES-256-GCM 实现更完整，替换主项目中的弱加密 |
|
||||
| B 目录 upstream/ | **参考并部分合并** | B 的上游客户端有更好的测试覆盖 |
|
||||
|
||||

|
||||
|
||||
## 四、分阶段重构路线图
|
||||
|
||||
### 阶段一：安全清零与基线修复（第 1-2 周）
|
||||
|
||||

|
||||
|
||||
### 阶段五：性能优化与生产准备（第 9-10 周）
|
||||
|
||||
**目标**: 生产环境可部署，性能基准建立。
|

**里程碑**: 通过生产环境部署演练，支撑 100 QPS 以上。
|
||||
|
||||
---
|
||||
|
||||
## 五、漂移目录清理
|
||||
|
||||
重构完成后，漂移目录应被清理以避免未来混淆：
|
||||
|
||||
```bash
|
||||
# 重构完成后执行
|
||||
rm -rf /home/long/hermes-agent/bridge/
|
||||
rm -rf /home/long/hermes-agent-official/bridge/
|
||||
|
||||
# 如需保留历史，则移动到归档目录
|
||||
mv /home/long/hermes-agent/bridge /home/long/archives/bridge-plan-2026-04-24
|
||||
mv /home/long/hermes-agent-official/bridge /home/long/archives/bridge-blueprint-2026-04-26
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 六、风险与回退策略
|
||||
|
||||
| 风险 | 影响 | 回退策略 |
|
||||
|------|------|---------|
|
||||
| 代码合并引入回归 | 主链路故障 | 每个合并 PR 单独评审，保持原仓库 tag 可回滚 |
|
||||
| 前端开发延期 | 整体进度拖后 | 阶段四可与阶段三并行，先保证 API 稳定 |
|
||||
| 安全修复突破兼容性 | 旧数据无法使用 | KMS 升级时实施双向兼容，逐步迁移 |
|
||||
| 测试补齐耗时 | 进度超预期 | 采用渐进式覆盖，先保证核心路径 80% |
|
||||
| 团队人手不足 | 无法按期完成 | 优先完成阶段一和阶段二，阶段三五可分批外包 |
|
||||
|
||||
---
|
||||
|
||||
## 七、验收标准汇总
|
||||
|
||||
| 检查项 | 通过标准 |
|
||||
|--------|---------|
|
||||
| 安全扫描 | `gosec -fmt sarif ./...` 高危+中危 = 0 |
|
||||
| 单元测试 | `go test ./...` 全绿 |
|
||||
| 覆盖率 | adapter ≥ 70%、repository ≥ 60%、domain ≥ 60% |
|
||||
| 真实环境 | `docker compose up -d` 启动后三套服务健康检查通过 |
|
||||
| 前端对接 | 可通过浏览器完成登录、订单、查询三个核心流程 |
|
||||
| 性能基准 | 100 QPS 下 P99 < 500ms |
|
||||
| 文档完整 | README 、API 文档 、部署文档 与代码一致 |
|
||||
|
||||
---
|
||||
|
||||
## 八、立即执行的下一步
|
||||
|
||||
1. 创建统一代码库 `bridge/` 并初始化 `go.work`
|
||||
2. 封装现有三个目录（主项目、A、B）为只读，确保基线可回滚
|
||||
3. 开启阶段一：按 S1-T1~S1-T13 顺序修复 P0/P1 缺陷
|
||||
4. 每日 standup 跟踪安全清零进度
|
||||
|
||||
**小龙，请确认：**
|
||||
- 是否立即启动阶段一（安全清零）？
|
||||
- 是否需要我先深入分析 B 目录的架构差异，输出具体的代码合并对照表？
|
||||
- 是否需要先创建统一代码库并完成物理合并？

# Gateway 模块规则
|
||||
|
||||
## 模块定位
|
||||
|
||||
`gateway` 是对外入口控制层，不是业务真源，也不是 token authority。它的职责是把入口请求安全、稳定、可观测地接进系统，并把鉴权、限流、上游路由、基础审计这些横切关注点处理干净。
|
||||
|
||||
这里最重要的是边界清晰、失败可控、兼容性稳定。不要把业务逻辑、授权真相、一次性试验代码偷偷塞进入口层。
|
||||
|
||||
## 第一原则
|
||||
|
||||
1. 入口层必须克制。
|
||||
`gateway` 负责接入和控制，不负责复制业务语义。尤其不要在这里重新发明 token authority 或供应链业务逻辑。
|
||||
|
||||
2. 兼容性是核心资产。
|
||||
对外 OpenAI 兼容接口、状态码、字段格式、错误行为的变更，默认视为高风险变更。
|
||||
|
||||
3. 默认保护共享环境。
|
||||
`inmemory`、弱鉴权、宽松 CORS、默认密钥等只允许开发环境使用；共享环境和生产环境必须显式 fail-closed。
|
||||
|
||||
4. 主链路优先于实验模块。
|
||||
只有接入 `cmd/gateway/main.go` 启动链路并通过关键验证的能力，才算当前真实交付范围。
|
||||
|
||||
## 运行边界
|
||||
|
||||
- token authority 的真源在 `platform-token-runtime`
|
||||
- `gateway` 只在 `remote_introspection` 模式下消费 introspection 结果
|
||||
- 未显式接入主链路的策略、fallback 模块或实验代码，不得在文档和结论中包装成“已上线能力”
|
||||
|
||||
## 变更前必须先判断
|
||||
|
||||
- 这是协议兼容变更、鉴权变更、路由变更、可观测性变更，还是部署/配置变更？
|
||||
- 会不会改变默认安全边界？
|
||||
- 会不会影响 `/v1/chat/completions`、`/v1/completions`、`/v1/models` 的兼容性？
|
||||
- 会不会影响与 `platform-token-runtime` 的接口契约？
|
||||
|
||||
## 高风险变更类型
|
||||
|
||||
- 鉴权模式切换
|
||||
- principal 字段语义变化
|
||||
- provider 装配逻辑变化
|
||||
- 路由策略默认值变化
|
||||
- CORS、密钥、审计、模型返回结构变化
|
||||
|
||||
这些改动默认要求更强验证，不接受“应该没问题”。
|
||||
|
||||
## 验证要求
|
||||
|
||||
### 至少覆盖
|
||||
|
||||
- 主接口 happy path
|
||||
- 认证失败路径
|
||||
- 上游错误或不可用路径
|
||||
- 配置缺失或非法配置路径
|
||||
|
||||
### 涉及兼容层时
|
||||
|
||||
- 必须验证 OpenAI 兼容路径和 `/api/v1/*` 兼容路径
|
||||
- 必须确认响应结构、错误码和关键字段没有无意漂移
|
||||
|
||||
### 涉及安全边界时
|
||||
|
||||
- 必须验证 `dev` 与非 `dev` 环境行为不同点
|
||||
- 必须确认条件能力未满足时明确拒绝，而不是静默放行
|
||||
|
||||
## 文档规则
|
||||
|
||||
- README 只记录“当前真实状态”，不要把实验能力写成默认行为
|
||||
- 新增策略或接口时，要明确说明是否已经接入主启动链路
|
||||
- 对降级、回退、默认值必须写清楚触发条件
|
||||
|
||||
## 禁止事项
|
||||
|
||||
- 不要在 `gateway` 内承载 token authority
|
||||
- 不要把实验路由策略伪装成正式能力
|
||||
- 不要让共享环境落到 `inmemory` 或宽松安全默认值
|
||||
- 不要把入口层改成难以观察和排障的黑盒

# Internal 目录规则
|
||||
|
||||
## 目录定位
|
||||
|
||||
`internal/` 承载系统内部共享能力、领域公共逻辑和跨模块复用部件。这里不是“放不下就往里塞”的杂物区，而是整个项目长期可维护性的关键层。
|
||||
|
||||
在这里的设计失误，通常不会立刻以接口错误暴露出来，但会持续放大耦合、重复、语义漂移和后续改造成本。
|
||||
|
||||
## 第一原则
|
||||
|
||||
1. 共享能力必须有明确边界。
|
||||
只有真正跨模块、稳定、可复用的能力才应该进入 `internal/`。一次性逻辑或只服务单一模块的细节不应提前上收。
|
||||
|
||||
2. 语义稳定优先于短期省事。
|
||||
进入共享层的结构体、接口、错误码、辅助函数，默认会影响多个模块，命名和行为必须克制且一致。
|
||||
|
||||
3. 不做伪抽象。
|
||||
如果抽象只是在把一段简单代码包成更难理解的通用层，那不是改进。
|
||||
|
||||
4. 内部共享层也必须可验证。
|
||||
即使不直接对外暴露，也要优先可测试、可推理、可替换，而不是隐藏复杂度。
|
||||
|
||||
## 适合放进这里的内容
|
||||
|
||||
- 多模块共享的基础类型、辅助库、公共校验
|
||||
- 跨模块一致性约束
|
||||
- 稳定的领域公共模型
|
||||
- 明确复用价值的中间层能力
|
||||
|
||||
## 不适合放进这里的内容
|
||||
|
||||
- 单一服务的临时逻辑
|
||||
- 只为减少 import 路径而上收的代码
|
||||
- 未验证是否真的复用的“预抽象”
|
||||
- 模糊归属、未来可能会用到的占位代码
|
||||
|
||||
## 变更要求
|
||||
|
||||
- 修改共享结构前，先确认受影响的模块集合
|
||||
- 公共接口或类型变更时，必须同步检查所有调用方
|
||||
- 如果一个改动会提升复用性但降低可读性，默认优先保护可读性
|
||||
|
||||
## 验证要求
|
||||
|
||||
- 至少验证直接调用方
|
||||
- 涉及公共类型、错误语义、工具函数时，尽量补单元测试
|
||||
- 不要只改定义，不验证实际使用行为
|
||||
|
||||
## 禁止事项
|
||||
|
||||
- 不要把 `internal/` 变成“无法归类代码”的默认落点
|
||||
- 不要在没有两个以上真实调用场景时提前抽共享层
|
||||
- 不要让共享层承载模块专属业务语义

# Platform-Token-Runtime 模块规则
|
||||
|
||||
## 模块定位
|
||||
|
||||
`platform-token-runtime` 是 token 生命周期、introspection 与审计查询的真源服务。这里承载的是身份与授权边界，不是普通业务接口。默认必须以 authority 的严肃程度来设计、修改和验证。
|
||||
|
||||
任何在这里的错误，都可能直接影响鉴权正确性、审计可信性和整个系统的安全边界。
|
||||
|
||||
## 第一原则
|
||||
|
||||
1. authority 必须单一真源。
|
||||
token 的签发、刷新、撤销、状态解释和 introspection 语义必须在这里集中收口，不能让其他服务复制或发散这些语义。
|
||||
|
||||
2. 字段边界必须稳定。
|
||||
canonical principal 的字段集合、含义、缺省行为和响应格式都是契约。变更默认是高风险。
|
||||
|
||||
3. 安全默认值优先。
|
||||
涉及 token、审计、身份边界时，默认 fail-closed；不能用“返回空”“假成功”“先兼容一下”代替明确拒绝。
|
||||
|
||||
4. 明文敏感数据绝不外泄。
|
||||
无论是响应、日志、错误、审计还是调试输出，都不能暴露 access token 明文。
|
||||
|
||||
## 变更分类
|
||||
|
||||
### 协议契约变更
|
||||
|
||||
- `issue` / `refresh` / `revoke` / `introspect` / `audit-events`
|
||||
- principal 字段
|
||||
- 状态枚举
|
||||
- 错误码/错误响应
|
||||
|
||||
这些改动默认必须视为外部契约变更。
|
||||
|
||||
### 存储层变更
|
||||
|
||||
- runtime store
|
||||
- audit store
|
||||
- PostgreSQL schema / DDL
|
||||
- 内存实现与数据库实现的行为一致性
|
||||
|
||||
这些改动必须同时考虑迁移、安全、兼容与查询语义。
|
||||
|
||||
## 验证要求
|
||||
|
||||
### 至少覆盖
|
||||
|
||||
- token 生命周期主路径
|
||||
- 无效 token / 过期 token / 撤销 token 路径
|
||||
- `dev` 与 `staging/prod` 下 store 装配差异
|
||||
- 数据库未配置时的行为
|
||||
- 审计查询返回语义
|
||||
|
||||
### 涉及 principal 字段时
|
||||
|
||||
- 必须同步检查 DDL、存储模型、HTTP 输出、OpenAPI 或文档说明
|
||||
- 必须验证不会因字段漂移导致 `gateway` 解析错误
|
||||
|
||||
### 涉及存储时
|
||||
|
||||
- 必须确认内存实现与 PostgreSQL 实现的关键行为一致
|
||||
- 不能只修一个 backend
|
||||
|
||||
## 文档规则
|
||||
|
||||
- 只记录当前真实 authority 行为
|
||||
- 明确哪些接口、字段和边界是 canonical
|
||||
- 对环境差异、快速失败条件、默认监听端口和装配逻辑要写清楚
|
||||
|
||||
## 禁止事项
|
||||
|
||||
- 不要在任何输出中泄露 token 明文
|
||||
- 不要把 query key、api_key 等旁路鉴权方式偷偷加回来
|
||||
- 不要让 `staging/prod` 在缺少关键依赖时静默回退到内存实现
|
||||
- 不要在未同步下游契约的前提下调整 principal 边界

- 文档结构最完整，且章节一致性最好。
|
||||
- 业务主链路最短：Webhook 接入 → Session → Intent → Reply/Handoff → Audit。
|
||||
- 风险可控，适合作为从文档到实现的第一条样板链路。
|
||||
- 相比 AI-Ops 和 Supply-Intelligence，外部依赖与状态机复杂度更低，更容易做最小闭环验证。
|
||||
|
||||
## 2. 实施目标
|
||||
|
||||
第一阶段只交付“最小生产可运行版本”，包含：
|
||||
1. 独立运行模式 HTTP 服务。
|
||||
2. 健康检查端点：`/actuator/health`、`/actuator/health/live`、`/actuator/health/ready`。
|
||||
3. Webhook 接口：最小文本消息接入。
|
||||
4. Session 管理：内存版会话存储。
|
||||
5. Intent 识别：规则版最小实现（不用真实 LLM）。
|
||||
6. Reply 生成：规则版 FAQ / fallback 回复。
|
||||
7. Handoff：敏感意图或低置信度转人工。
|
||||
8. Audit：内存版审计日志记录。
|
||||
9. OpenAPI 占位文档。
|
||||
10. 最小测试：主路径 + 失败路径。
|
||||
|
||||
非目标：
|
||||
- 不在第一阶段实现 PostgreSQL / Redis / 向量数据库。
|
||||
- 不在第一阶段实现真正 RAG 检索。
|
||||
- 不在第一阶段实现多渠道适配，只做单 webhook 文本入口。
|
||||
- 不在第一阶段实现完整 RBAC 后台。
|
||||
|
||||

```
|
||||
|
||||
## 4. 分阶段任务清单
|
||||
|
||||
### Phase 1：工程初始化
|
||||
1. 创建 Go module。
|
||||
2. 建立 `cmd/` + `internal/` 目录结构。
|
||||
3. 创建最小 `main.go`，支持 HTTP 启动。
|
||||
4. 增加 health handler。
|
||||
5. 增加基础 router。
|
||||
6. 写启动 smoke test。
|
||||
|
||||
### Phase 2：主链路实现
|
||||
1. 定义 `UnifiedMessage`、`Session`、`IntentResult`、`AuditEvent`。
|
||||
2. 实现 webhook handler：接收最小 JSON 文本消息。
|
||||
3. 实现 session store（memory）。
|
||||
4. 实现 intent service（规则匹配：quota/token/error/handoff/general）。
|
||||
5. 实现 reply service（规则回复/fallback）。
|
||||
6. 实现 handoff service（敏感词或低置信度转人工）。
|
||||
7. 实现 audit store（memory）。
|
||||
8. 打通主链路：receive → parse → intent → reply/handoff → audit。
|
||||
|
||||
### Phase 3：测试与门禁
|
||||
1. 单元测试：intent service。
|
||||
2. 单元测试：handoff service。
|
||||
3. 集成测试：dialog service。
|
||||
4. E2E 测试：webhook 主路径。
|
||||
5. E2E 测试：敏感词转人工失败路径。
|
||||
6. 验证 health/readiness 端点。
|
||||
7. 生成最小 OpenAPI 占位文档。
|
||||
|
||||
### Phase 4：运行工件
|
||||
1. 编写 Dockerfile。
|
||||
2. 编写最小 Makefile。
|
||||
3. 本地运行验证：`go test ./...`。
|
||||
4. 本地运行验证：启动服务并 curl health/webhook。
|
||||
|
||||
## 5. 阶段门禁
|
||||
|
||||
### Gate A：进入实现前
|
||||
- [x] PRD / HLD / TEST_DESIGN / INTERFACE 已存在。
|
||||
- [x] 文档中门禁、威胁建模、阻断条件已补齐。
|
||||
- [x] 工程目录已创建。
|
||||
|
||||
### Gate B：主链路完成
|
||||
- [x] 独立运行服务可启动。
|
||||
- [x] Webhook 能接收消息并返回应答。
|
||||
- [x] 敏感意图能够转人工。
|
||||
- [x] 审计事件会记录。
|
||||
|
||||
### Gate C：可交付最小版本
|
||||
- [x] `go test ./...` 全通过。
|
||||
- [x] health/live/ready 通过。
|
||||
- [x] 至少 1 条主路径 + 1 条失败路径 + 1 条转人工路径验证通过。
|
||||
- [x] Dockerfile 可构建。
|
||||
|
||||
## 6. 验证命令
|
||||
|
||||
```bash
|
||||
go test ./...
|
||||
go test ./test/e2e -v
|
||||
curl -i http://127.0.0.1:8080/actuator/health/live
|
||||
curl -i http://127.0.0.1:8080/actuator/health/ready
|
||||
curl -i -X POST http://127.0.0.1:8080/api/v1/customer-service/webhook \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{"message_id":"m1","channel":"widget","open_id":"u1","content":"查询额度"}'
|
||||
```
|
||||
|
||||
## 7. 风险与控制
|
||||
|
||||
1. 当前没有真实 LLM/RAG，先用规则实现，防止卡死在外部依赖。
|
||||
2. 先做内存存储，防止过早引入数据库和 Redis 增加噪声。
|
||||
3. 先独立运行，不先做集成模式，等主链路稳定后再补 IntegrationPlugin。
|
||||
4. 严禁把 demo 规则实现误标为生产完成；本计划交付的是“最小生产可运行原型”，不是最终版。

# AI-Customer-Service 生产上线执行方案
|
||||
|
||||
> 定位：本文件替代 demo/proto 导向的实施口径，作为小龙统筹 PM / TechLead / QA / Engineer 按生产上线标准推进的唯一执行基线。
|
||||
|
||||
## 1. 结论
|
||||
|
||||
当前 `ai-customer-service` **不具备生产上线条件**。
|
||||
|
||||
已完成的只是一个可运行原型，不能作为“阶段完成”或“可灰度上线”的依据。后续工作必须按生产项目方式推进，满足：
|
||||
- 文档与实现一致
|
||||
- 数据与审计可持久化
|
||||
- 权限、签名、幂等、隔离、防重放具备
|
||||
- 工单闭环真实存在
|
||||
- 外部依赖真实联通并可观测
|
||||
- 灰度、回滚、SLO、告警、Runbook 完整
|
||||
|
||||
## 2. 小龙团队职责重排
|
||||
|
||||
### 2.1 小龙（统筹）
|
||||
负责：
|
||||
- 统一生产一期范围，禁止再使用 MVP-proto 口径作为完成标准
|
||||
- 建立跨角色门禁，不允许“代码能跑”替代“产品可上线”
|
||||
- 每阶段只允许在 PM/TechLead/QA 共同签字后进入下一阶段
|
||||
- 对“文档说有、代码没有”“测试只测 happy path”直接打回
|
||||
|
||||
### 2.2 PM
|
||||
必须补齐：
|
||||
1. 《生产一期范围与门禁定义》
|
||||
2. 《客服 SLA 与升级响应规范》
|
||||
3. 《工单运营闭环 SOP》
|
||||
4. 《灰度发布与回滚 Runbook》
|
||||
5. 《客服运营后台需求说明》
|
||||
6. 《身份核验与数据权限策略》
|
||||
7. 《数据合规与留存策略》
|
||||
8. 《商业化与价值追踪方案》
|
||||
|
||||
### 2.3 TechLead
|
||||
必须补齐：
|
||||
1. 生产数据模型与 migration 方案

||||
3. Webhook 签名、防重放、幂等、审计 fail-closed 方案
|
||||
4. Ticket / Session / Audit / KB 真实架构
|
||||
5. IntegrationPlugin / 集成运行模式设计
|
||||
6. metrics / tracing / logging / health readiness 设计
|
||||
7. 降级、熔断、回滚、灰度技术方案
|
||||
|
||||
### 2.4 QA
|
||||
必须补齐：
|
||||
1. 文档-实现一致性检查清单
|
||||
2. 威胁建模到测试映射清单
|
||||
3. AC/失败路径/安全/性能/灾备测试矩阵
|
||||
4. 灰度与回滚演练检查表
|
||||
5. 实施漂移检测点
|
||||
6. 上线阻断条件清单
|
||||
|
||||
### 2.5 Engineer
|
||||
必须按文档和门禁实现，不得自行降级为：
|
||||
- 内存版替代持久化
|
||||
- 文本文案替代真实工单
|
||||
- 占位 OpenAPI 替代真实契约
|
||||
- 永远 UP 的 health 替代 readiness
|
||||
|
||||
## 3. 当前 P0 阻塞项
|
||||
|
||||
### P0-1 范围口径错误
|
||||
- 当前 `IMPLEMENTATION_PLAN.md` 仍使用 `MVP-proto` 口径。
|
||||
- 必须废弃其“已完成即可进入下一阶段”的含义。
|
||||
|
||||
### P0-2 持久化与数据模型缺失
|
||||
- Session / Audit / Knowledge 仍为内存实现。
|
||||
- 无 PostgreSQL schema / migration / rollback。
|
||||
|
||||
### P0-3 Webhook 安全链路缺失
|
||||
- 无签名校验、无防重放、无幂等、无限流。
|
||||
|
||||
### P0-4 工单闭环不存在
|
||||
- 当前转人工只返回文案，没有真实 ticket 创建、分配、处理、关闭。
|
||||
|
||||
### P0-5 身份核验与只读业务查询缺失
|
||||
- 无用户绑定、无 quota/token/error logs 真实查询。
|
||||
|
||||
### P0-6 权限与隔离缺失
|
||||
- 无鉴权、无 RBAC、无后台权限模型、无跨用户隔离验证。
|
||||
|
||||
### P0-7 审计不可靠
|
||||
- 审计不持久化，且当前是 fail-open。
|
||||
|
||||
### P0-8 可观测性与健康检查失真
|
||||
- 无 metrics/tracing/structured logging。
|
||||
- readiness/health 不检查依赖状态。
|
||||
|
||||
### P0-9 灰度/回滚不可执行
|
||||
- 文档有灰度与回滚要求，但代码与部署层无对应能力。
|
||||
|
||||
### P0-10 契约失真
|
||||
- OpenAPI / INTERFACE / router 实现明显不一致。

||||
|
||||
1. 废弃 demo 口径：重写 `IMPLEMENTATION_PLAN.md`
|
||||
2. 以生产底座为先，优先落地：
|
||||
- PostgreSQL migration
|
||||
- 持久化 Session/Audit/Ticket 基础模型

# AI-Customer-Service 生产一期执行状态
|
||||
|
||||
> 更新时间：基于当前代码现状人工核对。
|
||||
> 目的：把生产一期要求映射到当前实现边界，避免继续把原型能力误报为“已完成”。
|
||||
|
||||
## 1. 当前结论
|
||||
|
||||
当前项目仍处于**生产一期未完成**状态，但已具备以下已落地能力：
|
||||
|
||||
- 基础配置加载与 HTTP 超时/Body Limit 配置
|
||||
- webhook body schema 校验
|
||||
- webhook HMAC 签名与时间戳防重放校验
|
||||
- 消息幂等去重
|
||||
- 基于依赖检查的 `/actuator/health`、`/live`、`/ready`
|
||||
- 转人工工单创建
|
||||
- 工单列表 / 分配 / 解决最小闭环 API
|
||||
- 审计日志持久化写入
|
||||
- PostgreSQL migration 基础表结构
|
||||
|
||||
但距离“生产一期完成”仍有明显缺口，不能作为可灰度上线结论。

| readiness 检查依赖 | 已完成 | `internal/platform/health/dependency.go`, `internal/store/postgres/healthcheck.go` | 当前仅 postgres |
|
||||
| graceful shutdown | 已完成 | `internal/app/app.go` | |

|

## 3. 当前与文档的主要漂移
|
||||
|
||||
1. `tech/INTERFACE.md` 约定了按渠道 webhook（`/webhook/{channel}`），当前实现仍只有统一入口 `/api/v1/customer-service/webhook`。
|
||||
2. 文档要求人工接单/回复/关闭完整后台闭环，当前只做到 list/assign/resolve 最小 API。
|
||||
3. 文档要求安全事件审计，当前签名失败、时间戳失败、非法 body 不入审计。
|
||||
4. 文档要求更完整的运维可观测（metrics/tracing/SLO），当前尚未实现。
|
||||
|
||||
---
|
||||
|
||||
## 4. 剩余 P0 / P1 缺口排序
|
||||
|
||||
### P0（继续执行必须优先收口）
|
||||
|
||||
1. 工单状态流转审计补齐
|
||||
2. 安全拒绝事件审计补齐
|
||||
3. 工单 API 与接口文档对齐（至少明确当前最小契约）
|
||||
4. 工单关闭语义补齐或文档明确 resolve=关闭
|
||||
|
||||
### P1（生产一期仍必须完成）
|
||||
|
||||
1. webhook 速率限制
|
||||
2. 人工回复用户链路
|
||||
3. 排队位置查询
|
||||
4. metrics / tracing / SLO 基础设施
|
||||
5. 灰度/回滚 runbook
|
||||
|
||||
---
|
||||
|
||||
## 5. 本轮执行边界
|
||||
|
||||
本轮后续代码推进应聚焦：
|
||||
|
||||
1. 补齐安全拒绝审计
|
||||
2. 补齐工单状态流转审计
|
||||
3. 补齐工单关闭/文档对齐的最小闭环
|
||||
4. 扩展自动化测试覆盖主路径/失败路径/安全路径
|
||||
|
||||
在这些项完成前，不应把项目汇报为“生产一期已完成”。

> 版本：v1.0 | 状态：已生效
|
||||
> 关联：tech/INTERFACE.md、PRODUCTION_PHASE1_STATUS.md
|
||||
|
||||
---
|
||||
|
||||
## 1. 商业化模式
|
||||
|
||||
### 1.1 当前阶段定位
|
||||
|
||||
生产一期**不涉及商业化计费**，重点是建立可量化的价值追踪基础，为后续商业化提供数据支撑。
|
||||
|
||||
### 1.2 未来商业化模式（Phase 2+ 规划）
|
||||
|
||||
| 模式 | 说明 | 前提条件 |
|
||||
|------|------|----------|
|
||||
| 按会话量计费 | 每个机器人会话收取固定费用 | 计量系统完善 |
|
||||
| 按节省人工计费 | 机器人处理的会话替代了 N 个人工客服 | 准确率数据稳定 |
|
||||
| 按 API 调用计费 | 提供独立 API 供第三方调用 | API 鉴权完善 |
|
||||
| SaaS 订阅制 | 按租户/坐席数月费 | 多租户隔离完成 |
|
||||
|
||||
---
|
||||
|
||||
## 2. 核心价值指标（KVIs）
|
||||
|
||||
### 2.1 客服效率提升
|
||||
|
||||
| 指标 | 定义 | 计算方式 | 当前状态 |
|
||||
|------|------|----------|----------|
|
||||
| 机器人接待率 | 机器人接待的会话占总会话比例 | `机器人接待会话 / 总会话` | 待实现计量 |
|
||||
| 转人工率 | 需要人工介入的会话比例 | `转人工会话 / 总会话` | 待实现统计 |
|
||||
| 平均处理时长 | 客服处理单个工单的平均时间 | `SUM(resolve_time - create_time) / ticket_count` | ✅ 已记录 created_at/updated_at |
|
||||
| 机器人处理时长 | 机器人处理单个会话的平均时间 | `会话结束时间 - 会话开始时间（机器人部分）` | 待实现 |
|
||||
|
||||
### 2.2 成本节约
|
||||
|
||||
| 指标 | 定义 | 数据来源 | 当前状态 |
|
||||
|------|------|----------|----------|
|
||||
| 节省人工工时 | 机器人处理掉的会话 × 平均人工处理时长 | ticket + session 数据 | 待计量 |
|
||||
| 人工响应速度提升 | 用户从发起会话到首次人工响应的时长缩短 | 工单 created_at → assign 时间 | ✅ 已记录 |
|
||||
| 一站式解决率 | 用户无需再次联系即解决问题的比例 | 同一 user_id 在 7 天内无重复工单 | 待实现 |
|
||||
|
||||
### 2.3 用户体验
|
||||
|
||||
| 指标 | 定义 | 数据来源 | 当前状态 |
|
||||
|------|------|----------|----------|
|
||||
| 用户满意度 | 客服解决后用户评分（1-5 分） | 用户反馈 | 待实现 |
|
||||
| 机器人回答质量 | FAQ 命中后用户点"不满意"的比例 | 用户反馈 + FAQ 命中日志 | 待实现 |
|
||||
| 平均等待时长 | 用户从发消息到收到首次响应的时长 | session message timestamp | 待实现 |
|
||||

|
||||
|
||||
## 3. 价值追踪工具
|
||||
|
||||
### 3.1 运营大盘（待实现）
|
||||
|
||||
`tech/INTERFACE.md` 中定义的 `/admin/dashboard` 接口：
|
||||
|
||||
```json
|
||||
{
|
||||
"total_sessions_today": 1200,
|
||||
"robot_handled_sessions": 1020,
|
||||
"handoff_sessions": 180,
|
||||
"handoff_rate": "15%",
|
||||
"avg_robot_response_time_ms": 3200,
|
||||
"open_tickets": 12,
|
||||
"resolved_tickets_today": 45,
|
||||
"avg_resolution_time_minutes": 38,
|
||||
"top_handoff_reasons": [
|
||||
{ "reason": "refund", "count": 65 },
|
||||
{ "reason": "sensitive", "count": 40 },
|
||||
{ "reason": "unknown", "count": 75 }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**当前状态**：接口**已定义但未落地**，dashboard 数据聚合需要 session / ticket / message 数据的完整计量。
|
||||
|
||||
### 3.2 数据来源映射
|
||||
|
||||
| 指标 | 数据来源 | 当前状态 |
|
||||
|------|----------|----------|
|
||||
| 会话总量 | session 表 + message 表 | ✅ session store 已落地 |
|
||||
| 机器人处理量 | intent.needs_human = false 的 session | ✅ 对话服务已记录 |
|
||||
| 转人工量 | ticket 表（每个 ticket = 一次转人工） | ✅ 工单已落地 |
|
||||
| 响应时间 | message 表 timestamp | ✅ message 存储已落地 |
|
||||
| 解决时间 | ticket created_at → updated_at | ✅ 工单时间戳已落地 |
|
||||
|
||||

|
||||
|
||||
## 4. ROI 估算框架
|
||||
|
||||
### 4.1 输入参数（灰度阶段采集）
|
||||
|
||||
| 参数 | 估算值（待验证） | 数据来源 |
|
||||
|------|------------------|----------|
|
||||
| 机器人接待率 | 85% | 上线后统计 |
|
||||
| 转人工率 | 15% | 上线后统计 |
|
||||
| 平均人工处理时长 | 15 min/工单 | 灰度阶段记录 |
|
||||
| 机器人处理时长 | 1 min/会话 | 灰度阶段记录 |
|
||||
| 人工客服时薪 | ¥50/h | 运营数据 |
|
||||
|
||||
### 4.2 节约计算公式
|
||||
|
||||
```
|
||||
月度节约 = 机器人处理的会话数 × (平均人工处理时长 - 平均机器人处理时长) × 人工时薪
|
||||
|
||||
示例（待灰度验证）：
|
||||
月度会话量 = 50,000
|
||||
机器人处理 = 50,000 × 85% = 42,500
|
||||
人工处理 = 50,000 × 15% = 7,500
|
||||
|
||||
月度节约 = 42,500 × (15min - 1min) / 60 × ¥50
|
||||
= 42,500 × 0.233 × ¥50
|
||||
= ¥495,125/月
|
||||
```
|
||||
|
||||
> **注**：上述为理论估算，实际值需灰度阶段真实数据验证。

## 1. 灰度发布策略
|
||||
|
||||
### 1.1 灰度阶段定义
|
||||
|
||||
| 阶段 | 流量比例 | 持续时间 | 通过条件 |
|
||||
|------|----------|----------|----------|
|
||||
| 灰度 5% | 5% 新版本 / 95% 老版本 | 1-2 天 | 错误率 < 1%，无 P0/P1 问题 |
|
||||
| 灰度 20% | 20% 新版本 / 80% 老版本 | 2-3 天 | 错误率 < 0.5%，SLA 指标达标 |
|
||||
| 灰度 100% | 100% 新版本 | - | 灰度 20% 稳定 48h 后全量 |
|
||||
|
||||
### 1.2 灰度切换方式
|
||||
|
||||
**当前实现状态**：生产一期**灰度发布能力未落地**，尚无配置化灰度开关。
|
||||
|
||||
**临时方案**：通过 Kubernetes `Deployment` 副本数控制：
|
||||
- 灰度 5%：新版本 1 副本，老版本 19 副本
|
||||
- 灰度 20%：新版本 4 副本，老版本 16 副本
|
||||
- 全量：新版本 20 副本，老版本 0 副本
|
||||
|
||||
**正式方案（待实现）**：
|
||||
- 引入 feature flag 服务（LD / Apollo）
|
||||
- 按用户 ID、渠道、地区等维度灰度
|
||||
- 支持热开关，无需重启
|
||||

|
||||
|
||||
---
|
||||
|
||||
## 4. 回滚操作流程
|
||||
|
||||
### 4.1 当前状态
|
||||
|
||||
生产一期**自动回滚机制未落地**，依赖人工执行。
|
||||
|
||||
### 4.2 手动回滚步骤（当前临时方案）
|
||||
|
||||
```bash
|
||||
# 1. 确认当前版本和历史版本
|
||||
kubectl rollout history deployment/ai-customer-service
|
||||
|
||||
# 2. 查看当前版本状态
|
||||
kubectl get pods -l app=customer-service
|
||||
|
||||
# 3. 回滚到上一版本
|
||||
kubectl rollout undo deployment/ai-customer-service
|
||||
|
||||
# 4. 确认回滚成功
|
||||
kubectl rollout status deployment/ai-customer-service
|
||||
|
||||
# 5. 确认旧版本 pod 运行正常
|
||||
kubectl get pods -l app=customer-service
|
||||
```
|
||||
|
||||
### 4.3 回滚后检查
|
||||
|
||||
- [ ] `/actuator/health` 返回 `{"status":"up"}`
|
||||
- [ ] `/actuator/ready` 返回 `{"status":"up"}`
|
||||
- [ ] 手动测试 webhook 消息接收
|
||||
- [ ] 确认审计日志正常写入
|
||||
- [ ] 确认工单 API 正常工作
|
||||
|
||||
---
|
||||
|
||||
## 5. 故障恢复后的重新发布
|
||||
|
||||
当回滚后问题修复，需重新走灰度流程：
|
||||
|
||||
1. 问题根因分析完成
|
||||
2. 修复方案经过代码 review
|
||||
3. 在 staging/预发布环境验证
|
||||
4. 从灰度 5% 重新开始，不允许跳阶段

# 身份核验与数据权限策略
|

> 版本：v1.0 | 状态：已生效
|
||||
> 关联：tech/INTERFACE.md、PRODUCTION_PHASE1_STATUS.md
|

|
||||
|
||||
## 1. 身份核验
|
||||
|
||||
### 1.1 核验场景
|
||||
|
||||
客服系统需要处理两类身份核验：
|
||||
|
||||
| 场景 | 说明 |
|
||||
|------|------|
|
||||
| 用户身份核验 | 验证用户提供的邮箱/手机与注册信息匹配（用于敏感操作如退款查询） |
|
||||
| 客服身份核验 | 验证运营后台操作者的身份（防止越权操作） |
|
||||
|
||||
### 1.2 用户身份核验
|
||||
|
||||
**接口**（`tech/INTERFACE.md` 定义）：
|
||||
|
||||
| 接口 | 路径 | 说明 |
|
||||
|------|------|------|
|
||||
| 身份校验 | `GET /internal/supply/users/verify?email={email}` | 校验用户身份是否匹配 |
|
||||
| 配额查询 | `GET /internal/runtime/quota?user_id={uid}` | 查询用户配额 |
|
||||
| Token 消耗查询 | `GET /internal/runtime/token-usage?user_id={uid}&window=1d` | 查询 Token 消耗 |
|
||||
| 错误日志 | `GET /internal/runtime/error-logs?user_id={uid}&limit=5` | 查询错误日志 |
|
||||
|
||||
**当前状态**：上述接口**已定义但外部依赖（supply-api / token-runtime）尚未联调**，实际调用可能失败。
|
||||
|
||||
**核验流程**：
|
||||
1. 用户发起敏感操作（如查询退款状态）
|
||||
2. 系统要求用户输入邮箱 + 验证码
|
||||
3. 调用 supply-api 校验邮箱是否匹配用户 ID
|
||||
4. 匹配成功后执行操作，否则拒绝
|
||||
|
||||
### 1.3 身份核验失败处理
|
||||
|
||||
| 失败次数 | 处理方式 |
|
||||
|----------|----------|
|
||||
| 1-2 次 | 返回 `CS_IDT_4002`（验证码错误），允许重试 |
|
||||
| 3 次 | 返回 `CS_SES_4003`（身份校验已锁定），锁定 15 分钟 |
|
||||
| 锁定期间 | 所有身份核验请求返回 403，持续 15min 后自动解锁 |
|
||||
|
||||
> **注**：失败计数和锁定机制**当前未落地**（P0 缺口），身份校验只返回匹配结果，不做计数锁定。
|
||||
|
||||
---
|
||||
|
||||
## 2. 数据权限策略
|
||||
|
||||
### 2.1 权限基本原则
|
||||
|
||||
- 用户**只能查询自己的**会话、工单、Token 消耗数据
|
||||
- 客服**只能操作被分配的**工单
|
||||
- 管理员可以查看所有数据，但不得泄露给未授权第三方
|
||||
- 审计日志**不可篡改**，所有敏感操作均需记录
|
||||
|
||||
### 2.2 客服操作权限
|
||||
|
||||
| 操作 | agent | supervisor | admin |
|
||||
|------|-------|------------|-------|
|
||||
| 查看自己被分配的工单 | ✅ | ✅ | ✅ |
|
||||
| 查看所有工单 | ❌ | ✅ | ✅ |
|
||||
| assign 工单 | 仅自己的 | ✅ | ✅ |
|
||||
| resolve 工单 | 仅自己的 | ✅ | ✅ |
|
||||
| 查看转人工统计 | ❌ | ✅ | ✅ |
|
||||
| 查看运营大盘 | ❌ | ✅ | ✅ |
|
||||
| 敏感操作（退款） | ❌ | ✅ | ✅ |
|
||||
|
||||
> **注**：权限模型**当前未落地**（无 RBAC 实现），所有接口均为平权访问。Phase 4 运营后台需补充完整权限校验。
|
||||
|
||||
### 2.3 跨用户数据隔离
|
||||
|
||||
**当前状态**：`tech/INTERFACE.md` 中各接口的 user_id 隔离**依赖调用方传入正确的 user_id**，后端不做强制校验。
|
||||
|
||||
**缺失项（P0）**：
|
||||
- 所有查询类接口（sessions、tickets、quota 等）应强制要求带上 `user_id`，后端校验 `user_id` 归属，不允许跨用户查询
|
||||
- 客服操作工单时，后端应校验工单的 `user_id` 与当前操作者的权限范围
|
||||
|
||||
**建议方案**（待 TechLead 评审）：
|
||||
```
|
||||
// 中间件层增强
|
||||
func AuthMiddleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
claims := getJWTClaims(r)
|
||||
ctx := context.WithValue(r.Context(), "user_id", claims.UserID)
|
||||
ctx = context.WithValue(ctx, "role", claims.Role)
|
||||
next.ServeHTTP(w, r.WithContext(ctx))
|
||||
})
|
||||
}
|
||||
|
||||
// 处理器层校验
|
||||
func (h *TicketHandler) GetTicket(w http.ResponseWriter, r *http.Request) {
|
||||
userID := r.Context().Value("user_id")
|
||||
ticketID := mux.Vars(r)["id"]
|
||||
ticket := h.store.GetTicket(ticketID)
|
||||
|
||||
role := r.Context().Value("role")
|
||||
if role != "admin" && role != "supervisor" && ticket.UserID != userID {
|
||||
writeError(w, "CS_AUTH_4001", 403) // 越权访问
|
||||
return
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 3. Webhook 身份校验
|
||||
|
||||
### 3.1 已落地
|
||||
|
||||
- **HMAC 签名校验**（`webhook_security.go`）：验证请求来自合法渠道
|
||||
- **时间戳防重放**（`webhook_security.go`）：防止 replay attack
|
||||
- **幂等去重**（`dedup_store.go`）：防止重复消息
|
||||
|
||||
### 3.2 待补充
|
||||
|
||||
| 项目 | 优先级 | 说明 |
|
||||
|------|--------|------|
|
||||
| webhook 速率限制 | P1 | 防止恶意刷请求 |
|
||||
| 渠道级独立 webhook 路由 | P0 | INTERFACE 定义 `/webhook/{channel}`，当前统一入口 |
|
||||
|
||||

|
||||
|
||||
## 4. 敏感数据处理
|
||||
|
||||
### 4.1 敏感字段
|
||||
|
||||
| 字段 | 处理方式 |
|
||||
|------|----------|
|
||||
| 用户邮箱 | 脱敏展示（后三位 + `@` 前的后三位），如 `t***@gmail.com` |
|
||||
| 用户手机 | 脱敏展示（后四位），如 `***-****-1234` |
|
||||
| API Key | 仅返回前缀后四字符，如 `sk-****-abcd` |
|
||||
| 退款金额 | 日志脱敏，接口明文返回（须登录态） |
|
||||
|
||||
### 4.2 当前状态
|
||||
|
||||
敏感数据脱敏**当前未落地**，所有字段明文返回。
|
||||
|

|
||||
|
||||
## 5. 审计日志与权限审计
|
||||
|
||||
### 5.1 已落地
|
||||
|
||||
- **审计日志持久化**（`audit_store.go`）：写入 PostgreSQL `cs_audit_logs` 表
|
||||
- **fail-closed**：审计写入失败时整体请求返回错误
|
||||
- **source_ip / actor_id**：记录操作来源（actor_id 当前有默认值 fallback）
|
||||
|
||||
### 5.2 待补充
|
||||
|
||||
| 项目 | 优先级 | 说明 |
|
||||
|------|--------|------|
|
||||
| 安全拒绝事件审计 | P0 | 签名失败、时间戳失败不记审计 |
|
||||
| 工单状态流转审计 | P0 | assign/resolve 未写审计 |
|
||||
| source_ip 字段缺失 | P0 | audit_store 当前未写 source_ip |

## 3. 运营后台需求清单（生产一期范围）
|
||||
|
||||
### 3.1 核心需求（生产一期必须落地）
|
||||
|
||||
#### P0：工单运营视图
|
||||
|
||||
**需求描述**：客服人员可通过后台看到所有工单，并执行分配/解决操作。
|
||||
|
||||
**已落地**：
|
||||
- 工单列表（按 status / assigned_to / priority 过滤）
|
||||
- 工单分配（assign）
|
||||
- 工单解决（resolve）
|
||||
- 工单统计（总计、各状态数量）
|
||||
|
||||
**已收口 P0 缺口**：
|
||||
- ✅ 工单状态流转审计（assign/resolve/close 均通过 `TicketWorkflowStore.writeAudit` 写入审计日志）
|
||||
- ✅ 工单关闭语义（resolve=已解决关闭；另有独立 close 接口支持显式关闭）
|
||||
|
||||
#### P1：转人工原因分析
|
||||
|
||||
**需求描述**：运营团队需要看到转人工的原因分布，用于优化机器人回答质量。
|
||||
|
||||
**当前状态**：代码中 `handoff_service.CreateTicket` 记录了 `handoff_reason`，但**无专门的后台聚合接口**。
|
||||
|
||||
**待实现**：
|
||||
- `GET /api/v1/customer-service/admin/handoff-reasons` — 按原因聚合统计
|
||||
- 关联 `tech/INTERFACE.md` 中已定义的 `/admin/handoff-reasons` 接口
|
||||
|
||||
#### P1：会话历史查看
|
||||
|
||||
**需求描述**：客服处理工单时需要查看用户完整的对话历史。
|
||||
|
||||
**当前状态**：`GET /api/v1/customer-service/sessions/{id}/messages` 接口**已定义但未完全落地**。
|
||||

# 立交桥智能客服系统 PRD
|
||||
|
||||
## 1. 概述
|
||||
|
||||
### 一句话价值
|
||||
在立交桥多平台Gateway（Telegram、Discord、微信等）上构建一套可自动解决用户初始化与使用过程问题的智能客服系统，将人工客服介入率降低 60% 以上。
|
||||
|
||||
### 用户问题
|
||||
- 终端用户在初始化API Key、配置模型路由、排查配额/计费异常时，缺乏 7×24 自助诊断能力，导致问题滞留或流失。
|
||||
- 内部运营/客服人员面对重复性咨询（占总量 70%+）无法释放精力处理复杂客诉与舆情。
|
||||
|
||||
### 业务意义
|
||||
- 降低单用户服务成本（Cost Per Ticket）。
|
||||
- 缩短首次响应时间与问题解决时间（MTTR）。
|
||||
- 通过客服交互数据反哺产品文档缺失点与系统易用性缺陷。
|
||||
|
||||
---
|
||||
|
||||
## 2. 目标
|
||||
|
||||
### 业务目标
|
||||
| 目标 | 基准值 | 目标值 | 观测周期 |
|
||||
|---|---|---|---|
|
||||
| 人工客服介入率 | 100% | ≤ 40% | 上线后 30 天 |
|
||||
| 首次响应时间 | 人工排班时段内 | ≤ 10 秒（任意时段） | 上线后 30 天 |
|
||||
| 常见问题一次解决率 | 0 | ≥ 75% | 上线后 30 天 |
|
||||
| 用户满意度（CSAT） | 无 | ≥ 4.0 / 5.0 | 上线后 30 天 |
|
||||
|
||||
### 用户目标
|
||||
- 终端用户：在任意渠道发起咨询后，10 秒内获得有效反馈；复杂问题可在 24 小时内得到明确处理结论。
|
||||
- 内部运营/客服人员：每日重复性问题处理量减少 60%，工单系统仅接收需人工判断或敏感操作的请求。
|
||||
|
||||
### 成功定义
|
||||
上线 30 天后，同时满足：
|
||||
1. 人工客服介入率 ≤ 40%。
|
||||
2. 常见问题一次解决率 ≥ 75%。
|
||||
3. 系统可用性 ≥ 99.5%（基于健康检查与告警数据）。
|
||||
4. 未发生因客服系统导致的数据泄露或权限越界事件（安全审计通过）。
|
||||
|
||||
---
|
||||
|
||||
## 3. 范围
|
||||
|
||||
### In Scope
|
||||
1. **多渠道接入层**：通过立交桥现有 `gateway/` 接入 Telegram Bot、Discord Bot、微信公众号/小程序客服消息、网页嵌入式 Widget（至少覆盖这 4 个渠道）。
|
||||
2. **对话引擎**：基于大模型的意图识别、上下文多轮对话、知识库检索增强生成（RAG）、工单自动生成。
|
||||
3. **知识库管理**：立交桥产品文档（初始化、API Key 管理、模型路由、配额/计费、错误码释义）的结构化索引与更新机制。
|
||||
4. **诊断能力**：对接 `platform-token-runtime/` 与 `supply-api/` 的只读查询接口，实现用户身份核验、配额查询、Token 消耗追溯、最近 5 条错误日志检索。
|
||||
5. **转人工机制**：当置信度低于阈值、用户明确要求人工、或问题涉及账户封禁/退款/安全审计时，自动创建工单并通知人工客服队列。
|
||||
6. **运营后台**：内部运营/客服人员使用的工单看板、会话历史查询、知识库条目增删改查、转人工原因统计。
|
||||
7. **埋点与监控**：全链路日志、对话转化率、转人工原因分布、响应延迟 P99、错误率。
|
||||
|
||||
### Out of Scope
|
||||
1. **电话/语音客服**：本期仅覆盖文本渠道，不接入语音呼叫中心。
|
||||
2. **主动外呼/营销推送**：客服系统仅响应用户主动发起的咨询，不包含主动触达或营销场景。
|
||||
3. **多语言支持**：本期优先中文，英文作为 P1 后续迭代，其他语言明确不在本期。
|
||||
4. **实时视频/屏幕共享**：诊断过程不提供远程桌面或屏幕共享能力。
|
||||
5. **直接修改用户数据**：客服系统仅拥有只读查询权限，任何写操作（如重置密码、修改配额）必须通过工单由人工授权后由独立管理后台执行。
|
||||
6. **模型训练/微调基础设施**：不自建模型训练流水线，使用现有大模型 API（如 GPT-4o / Claude / 国内等效模型）通过 Prompt 工程与 RAG 满足需求。
|
||||
|
||||
### 假设与依赖
|
||||
- 假设立交桥 `gateway/` 的 Telegram / Discord / 微信接口已具备 Webhook 接收与消息推送能力，客服系统以独立服务形式接入，不改造 gateway 核心路由逻辑。
|
||||
- 假设 `platform-token-runtime/` 与 `supply-api/` 能提供稳定的只读查询 API（用户身份、配额、Token 消耗、近期错误日志），并具备速率限制与鉴权契约。
|
||||
- 依赖大模型 API 供应商的可用性与 SLA（需配置多供应商 failover）。
|
||||
- 依赖现有用户体系（OAuth / API Key）可用于客服渠道的身份关联。
|
||||
|
||||
---
|
||||
|
||||
## 4. 用户场景
|
||||
|
||||
### 4.1 主流程：用户自助解决常见问题
|
||||
|
||||
```
|
||||
1. 用户通过 Telegram / Discord / 微信 / 网页 Widget 发起文本咨询。
|
||||
2. Gateway 将消息路由至智能客服系统。
|
||||
3. 系统执行身份关联：
|
||||
a. 若渠道已绑定立交桥账户，提取 user_id。
|
||||
b. 若未绑定，请求用户提供注册邮箱或 API Key 前缀进行一次性核验（不存储完整 API Key）。
|
||||
4. 系统进行意图识别与知识库检索（RAG）。
|
||||
5. 若意图命中已知问题且置信度 ≥ 0.85：
|
||||
a. 返回结构化答案（含操作步骤、文档链接、代码示例）。
|
||||
b. 若答案涉及用户个人数据（如配额），调用 supply-api / runtime 只读接口查询后嵌入回复。
|
||||
6. 用户确认问题是否解决：
|
||||
a. 用户反馈“已解决” → 会话关闭，记录解决标记。
|
||||
b. 用户反馈“未解决”或继续追问 → 进入多轮对话，最多 3 轮；仍无法解决则触发转人工。
|
||||
```
|
||||
|
||||
### 4.2 异常流程：身份核验失败
|
||||
|
||||
```
|
||||
1. 用户提供邮箱或 API Key 前缀无法匹配系统记录。
|
||||
2. 系统回复：“未找到关联账户，请核对注册邮箱或联系人工客服处理账户问题。”
|
||||
3. 同一会话中身份核验失败累计 3 次 → 自动触发转人工工单，并标记“身份核验失败”。
|
||||
4. 系统不记录错误的 API Key 或密码，仅记录失败次数与事件类型。
|
||||
```
|
||||
|
||||
### 4.3 异常流程：大模型 API 故障或超时
|
||||
|
||||
```
|
||||
1. 系统在 5 秒内未收到大模型 API 响应。
|
||||
2. 触发 failover：按优先级切换至备用模型供应商（配置至少 2 家）。
|
||||
3. 若 failover 后 5 秒内仍无响应：
|
||||
a. 返回兜底回复：“当前咨询量较大，请稍等或提交工单由人工处理。”
|
||||
b. 自动生成工单，并附带用户原始问题与会话上下文。
|
||||
c. 记录故障事件至监控告警系统。
|
||||
```
|
||||
|
||||
### 4.4 边缘流程：用户明确要求人工
|
||||
|
||||
```
|
||||
1. 用户发送包含“人工客服”、“找人工”、“投诉”等明确关键词的消息。
|
||||
2. 系统绕过自动回复逻辑，立即确认：“正在为您转接人工客服，预计排队时间 X 分钟。”
|
||||
3. 生成工单并推送到客服队列；若队列空闲，立即分配；若排队超过 15 分钟，向用户发送排队进度通知。
|
||||
```
|
||||
|
||||
### 4.5 边缘流程：涉及敏感操作（退款、封禁、安全审计）
|
||||
|
||||
```
|
||||
1. 意图识别命中“退款申请”、“账户被封禁”、“怀疑数据泄露”等敏感意图。
|
||||
2. 系统自动回复：“该问题需要人工核实，已为您创建优先工单，客服将在 24 小时内通过邮件/站内信回复。”
|
||||
3. 工单标记为高优先级（P1），并触发内部通知（企业微信/钉钉/Slack）。
|
||||
4. 客服系统本身不执行任何账户状态变更或资金操作。
|
||||
```
|
||||
|
||||

## 6. 边缘情况与失败路径
|
||||
|
||||
| 编号 | 场景 | 预期行为 | 监控/告警 |
|
||||
|---|---|---|---|
|
||||
| EC-01 | 用户发送超长消息（> 2000 字） | 截断至 2000 字后处理，并在回复中提示 "消息较长，已处理前 2000 字，如需补充请分段发送" | 记录截断事件，不告警 |
|
||||
| EC-02 | 用户在 1 秒内连续发送 10 条消息 | 启用频率限制：合并为 1 条上下文，回复后解锁；若 1 分钟内触发 3 次频率限制，临时静默 60 秒并提示 | 触发风控埋点，达到阈值时告警 |
|
||||
| EC-03 | 知识库检索无结果且意图置信度 < 0.60 | 直接触发转人工，回复 "该问题暂未收录，已为您转接人工客服" | 记录 "知识库未命中" 事件，每日汇总 |
|
||||
| EC-04 | 用户提供的 API Key 前缀匹配到多个账户 | 请求补充注册邮箱进行二次核验；若仍无法唯一确定，转人工 | 记录模糊匹配事件 |
|
||||
| EC-05 | supply-api / runtime 查询超时（> 3 秒） | 回复中省略个人数据部分，仅提供通用说明，并提示 "账户数据查询暂时不可用，请稍后重试或联系人工" | 触发依赖服务超时告警 |
|
||||
| EC-06 | 同一用户在多渠道同时发起会话 | 各渠道会话独立处理，不强制合并；若用户身份已绑定，客服后台可查看该用户全渠道最近 5 条会话摘要 | 记录多渠道并发事件 |
|
||||
| EC-07 | 用户发送非文本内容（图片、文件、语音） | 回复 "暂不支持该类型消息，请用文字描述您的问题"；图片若包含二维码或敏感信息，不解析、不存储 | 记录消息类型分布 |
|
||||
| EC-08 | 系统维护窗口期（计划内停机） | 提前 24 小时在 Gateway 层配置维护公告，用户消息收到固定回复 "客服系统维护中，预计 X 点恢复，紧急问题请发邮件至 support@example.com"；不生成工单积压 | 维护期间关闭自动工单生成，维护结束后恢复 |
|
||||
| EC-09 | 客服队列满员（> 20 个未处理 P1/P2 工单） | 新工单仍生成，但向用户提示 "当前人工客服繁忙，预计等待时间超过 30 分钟，建议您先查看帮助文档 [链接]"；触发运营 Slack 告警 | 队列深度超过阈值触发 P1 告警 |
|
||||
| EC-10 | 数据库连接池耗尽 | 新会话进入降级模式：仅返回静态 FAQ 链接，不执行查询、不生成工单；健康检查返回非 200，触发容器重启或扩容 | 触发 P0 告警 |
|

## 7. 上线与运营准备
|
||||
|
||||
### 7.1 发布策略
|
||||
- **Phase 1（灰度）**：仅对网页 Widget 渠道开放，覆盖 10% 流量，持续 3 天。观察 MTTR、转人工率、模型幻觉率。
|
||||
- **Phase 2（扩展）**：开放 Telegram 与 Discord 渠道，覆盖 50% 流量，持续 5 天。
|
||||
- **Phase 3（全量）**：开放微信渠道，100% 流量。保留 1 周内一键关闭各渠道客服系统路由的 Gateway 配置开关。
|
||||
|
||||
### 7.2 灰度/回滚
|
||||
- **Gateway 层回滚**：每个渠道的 Webhook 路由配置独立，可在 1 分钟内将某渠道消息路由回原有处理逻辑（或静默丢弃后引导至邮件）。
|
||||
- **模型层回滚**：模型供应商配置存储于配置中心，可在 30 秒内切换主备模型或关闭大模型调用（进入静态回复模式）。
|
||||
- **数据库回滚**：知识库与工单数据使用独立 schema，不影响立交桥核心用户/配额数据；发布前执行 schema 备份。
|
||||
|
||||

|
||||
|
||||
## 8. 商业化与价值闭环
|
||||
|
||||
### 收益路径
|
||||
1. **成本降低**：将单 ticket 人工成本从当前 100% 人工处理降至 ≤ 40% 人工处理，释放客服人力投入高价值客诉与运营活动。
|
||||
2. **留存提升**：7×24 自助服务减少用户因等待回复而放弃使用的场景，提升次日/周留存率。
|
||||
3. **产品改进**：通过转人工原因分布与知识库未命中数据，定向补充产品文档、优化错误提示、改进 onboarding 流程，减少未来咨询量。
|
||||
4. **可定价增值服务**：未来可将 "专属客服通道"、"1 对 1 技术支持" 作为企业版或高阶套餐的增值服务。
|
||||
|
||||
### 北极星指标
|
||||
- **自助问题解决率** = （机器人会话且用户标记已解决数） / （机器人总会话数 - 明确转人工会话数）
|
||||
- 目标：上线 30 天后 ≥ 75%
|
||||
|
||||
### 失败判定线
|
||||
满足以下任一条件即判定本期交付失败，需启动复盘与止损：
|
||||
1. 上线 14 天后，人工介入率仍 > 70%（说明自动回复未产生实质替代效果）。
|
||||
2. 上线 7 天内，发生 ≥ 2 起用户数据泄露或权限越界事件。
|
||||
3. 上线 30 天后，用户满意度 CSAT < 3.0 / 5.0。
|
||||
4. 系统可用性在任意 7 天滑动窗口内 < 99%。
|
||||
|
||||
### 止损条件
|
||||
- **立即下线**：发现客服系统接口可被未授权访问并读取其他用户数据；或模型回复中系统性地泄露内部系统架构、密钥信息。
|
||||
- **停止扩量**：Phase 1/2 中单日转人工率 > 90%，或模型幻觉率（事实性错误被客服标记）> 20%。
|
||||
- **技术债熔断**：若开发过程中发现需改造 `gateway/` 核心鉴权/路由逻辑才能接入，则退回评估，改为独立邮件/工单形式交付，不强行耦合。

## 9. 依赖与风险
|
||||
|
||||
### 依赖项
|
||||
| 依赖 | 提供方 | 状态要求 | 风险等级 |
|
||||
|---|---|---|---|
|
||||
| Gateway Webhook 接入能力 | `gateway/` 团队 | 已具备 Telegram/Discord/微信消息接收与回复接口 | 中 |
|
||||
| 用户身份与配额只读 API | `platform-token-runtime/` / `supply-api/` | 提供带鉴权的只读查询接口，延迟 < 500ms，可用性 ≥ 99.9% | 高 |
|
||||
| 大模型 API 供应商（已接入运营商中选择） | 外部（至少 2 家，从已接入的主流运营商中选择） | 确认 SLA、TPM 限额，签署数据保密协议，支持 Failover | 高 |
|
||||

|
||||
| 客服工单数据库 | 本项目新设 | Schema 定稿、迁移脚本可回滚 | 低 |
|
||||
|
||||
### 风险清单
|
||||
| 风险 | 影响 | 概率 | 缓解措施 |
|
||||
|---|---|---|---|
|
||||
| 大模型幻觉导致错误指导用户配置，引发业务损失 | 高 | 中 | 1. 限制回答范围至知识库内容；2. 涉及操作步骤必须附带官方文档链接；3. 运营每日抽检 5% 对话；4. 高风险意图（计费、安全）强制转人工 |
|
||||
| 用户通过 Prompt Injection 诱导客服系统泄露敏感数据 | 高 | 中 | 1. 系统 Prompt 中明确禁止回复非当前用户数据；2. 所有数据查询强制携带 user_id 校验；3. 安全审计日志全量记录；4. 定期红队测试 |
|
||||
| 模型供应商 API 涨价或停服 | 中 | 低 | 1. 至少签约 2 家供应商并具备 30 分钟内切换能力；2. 核心兜底回复不依赖大模型（静态模板）；3. 评估开源本地模型作为极端降级方案 |
|
||||
| 接入 Gateway 改造成本超出预期 | 中 | 中 | 1. Phase 1 先验证网页 Widget 独立接入；2. 明确客服系统不改造 Gateway 核心路由，仅增加旁路 Webhook |
|
||||
| 知识库维护跟不上产品迭代速度 | 中 | 高 | 1. 产品文档变更时同步更新知识库为发布 checklist 项；2. 每周生成知识库未命中报告，驱动文档补充；3. 预留半日/周的运营人力 |
|
||||

|
||||
|
||||
## 10. 技术栈与集成约束
|
||||
|
||||
### 统一技术栈
|
||||
本项目必须与立交桥主项目保持一致：
|
||||
- **语言**: Go 1.22+
|
||||
- **HTTP框架**: 标准库 `net/http` + 自定义中间件（禁止引入 Gin/Echo 等第三方框架，保持与 gateway/ 和 supply-api/ 的一致性）
|
||||
- **数据库**: PostgreSQL 15+ ，驱动 `jackc/pgx/v5`
|
||||
- **缓存**: Redis，客户端 `redis/go-redis/v9`
|
||||
- **配置**: YAML + Viper，环境变量覆盖敏感字段
|
||||
- **日志/审计**: 结构化日志，审计事件模型与 supply-api/ 一致
|
||||
- **错误码**: `{SOURCE}_{CATEGORY}_{CODE}` 格式，例如 `CS_SES_4001`
|
||||
- **健康检查**: `/actuator/health` 、 `/actuator/health/live` 、 `/actuator/health/ready`
|
||||
- **测试**: Go testing + testify，覆盖率门槛 domain ≥ 70%、service/handler ≥ 80%
|
||||
|
||||
### 独立运行与集成运行
|
||||
本系统必须同时支持两种运行模式：
|
||||
|
||||
| 模式 | 特征 | 部署方式 | 适用场景 |
|
||||
|------|------|---------|---------|
|
||||
| **独立运行** | 自有 `cmd/ai-customer-service/main.go`，独立数据库 schema，独立 docker-compose | `docker-compose up` 或单独容器 | 外部用户只需要客服能力，不想接入立交桥全套 |
|
||||
| **集成运行** | 作为 Go module 被 `gateway/` 引入，共享数据库连接池和配置，通过内部接口注册 | 编译时作为子模块编译，运行时挂载到 gateway 主进程 | 立交桥用户希望获得一体化客服能力 |
|
||||
|
||||
**集成约束**:
|
||||
- 独立运行时，系统必须提供完整的 HTTP API 、Webhook 接入和运营后台。
|
||||
- 集成运行时，系统必须提供 `IntegrationPlugin` 接口，允许主程序通过配置开关启用/禁用各模块。
|
||||
- 数据库 schema 必须使用独立的 `cs_` 前缀，避免与主项目表名冲突。
|
||||
- 配置文件必须支持分离加载：独立运行时读取自己的 `config.yaml`，集成运行时合并到主项目配置。
|
||||
|
||||
### NewAPI / Sub2API 适配支持
|
||||
本系统的核心能力必须能够对接 NewAPI 和 Sub2API 系统：
|
||||
- **Webhook 接入**: 提供标准化的 Webhook 接口，NewAPI/Sub2API 可配置将用户消息转发至本系统。
|
||||
- **工单推送**: 提供标准化工单接口，NewAPI/Sub2API 可定期获取待处理工单状态。
|
||||
- **知识库共享**: 提供知识库查询接口，NewAPI/Sub2API 可消费此数据补充自己的帮助文档。
|
||||
- **独立部署时**: 通过配置文件指定 NewAPI/Sub2API 的 Webhook 地址和鉴权信息，本系统通过适配层（Adapter）与之交互。
|
||||
- **集成部署时**: 若立交桥 gateway/ 已接入 NewAPI/Sub2API，本系统通过 gateway/ 的内部路由接口接入客服能力。
|
||||
|
||||
### 对外接口契约
|
||||
- 必须提供 OpenAPI 3.0 接口文档，确保 NewAPI/Sub2API 开发者可以独立接入。
|
||||
- 接口路径前缀默认为 `/api/v1/customer-service/`，集成运行时可通过配置改为 `/internal/customer-service/` 。
|
||||

## 11. 阶段门控结论
|
||||
|
||||
### 当前状态：需补充信息后方可进入 TechLead
|
||||
|
||||
### 待澄清项（阻塞性）
|
||||
1. ~~**Gateway Webhook 契约确认**：`gateway/` 团队需书面确认 Telegram / Discord / 微信消息的 Webhook 格式、鉴权方式、回复接口的速率限制，以及是否允许客服系统以独立服务形式接入而不改造核心路由。~~ ✅ **已确认：允许独立服务旁路接入。**
|
||||
2. **只读 API 契约确认**：`platform-token-runtime/` 与 `supply-api/` 团队需提供可对外暴露的只读接口清单（用户身份核验、配额查询、Token 消耗、近期错误日志），包括接口路径、请求/响应 Schema、鉴权方式、QPS 限制。
|
||||
3. **数据合规与隐私评估**：需法务/安全团队确认客服系统存储用户对话记录、查询用户 Token 消耗的合规性要求（尤其是涉及跨境渠道如 Telegram / Discord 时）。
|
||||
4. **大模型供应商选型**：需明确已接入的主流模型运营商（如 OpenAI / Anthropic / 阿里云 / 火山引擎 / 百度等），主备配置从已接入运营商中选择至少 2 家，并确认各运营商的 SLA、TPM 限额和数据保密协议签署状态。
|
||||
|
||||
### 非阻塞性建议
|
||||
- 建议在 TechLead 阶段前完成向量数据库选型（Milvus vs Qdrant vs PGVector）的 POC，验证中文语义检索延迟 < 200ms。
|
||||
- 建议提前准备 20 条高频问题的标准答案与文档链接，作为知识库种子数据。
|
||||
|
||||
### 门控决策记录
|
||||
- 若上述 4 项阻塞性待澄清项在 5 个工作日内全部确认，则门控结论更新为 **可进入 TechLead**。
|
||||
- 若任一项无法确认（如 Gateway 不允许独立旁路接入、只读 API 无法提供、合规评估不通过），则门控结论维持 **退回重新定义**，并调整方案为独立邮件/工单系统，不与 Gateway 实时渠道耦合。
|
||||
- **技术栈与集成约束已明确**：统一 Go 标准库、独立/集成双模式、NewAPI/Sub2API 适配层已纳入范围。
|
||||

# 生产一期范围与门禁定义
|
||||
|
||||
> 版本：v1.0 | 状态：已生效
|
||||
> 关联：PRODUCTION_EXECUTION_PLAN.md、PRODUCTION_PHASE1_STATUS.md、tech/INTERFACE.md
|

|
||||
---
|
||||
|
||||
## 1. 生产一期目标定位
|
||||
|
||||
生产一期是 ai-customer-service 从原型验证到生产可用的第一步。目标不是功能完备，而是**入口安全、闭环真实、运维可控**，在有限范围内做到生产级别质量。
|
||||
|
||||
---
|
||||
|
||||
## 2. 已落地能力（生产一期基线）
|
||||
|
||||
以下能力已在代码中实现并通过验证：
|
||||
|
||||
| 能力 | 代码位置 | 说明 |
|
||||
|------|----------|------|
|
||||
| webhook HMAC 签名校验 | `internal/http/handlers/webhook_security.go` | HMAC-SHA256，skew 校验 |
|
||||
| 时间戳防重放 | `internal/http/handlers/webhook_security.go` | skew window 内有效 |
|
||||
| 消息幂等去重 | `internal/store/postgres/dedup_store.go` | `(channel, message_id)` 去重 |
|
||||
| 工单创建 | `internal/service/dialog/service.go` | 退款/敏感意图触发转人工 |
|
||||
| 工单持久化 | `internal/store/postgres/ticket_store.go` | PostgreSQL |
|
||||
| 工单列表/分配/解决 | `internal/http/handlers/ticket_handler.go` | `GET /tickets`、`POST /assign`、`POST /resolve` |
|
||||
| 审计日志持久化 | `internal/store/postgres/audit_store.go` | 写入 `cs_audit_logs`，fail-closed |
|
||||
| 健康检查 | `internal/http/handlers/health_handler.go` | `/live`、`/ready`（含 PostgreSQL 依赖检查） |
|
||||
| 请求体大小限制 | `internal/platform/httpx/limits.go` | 全局 BodyLimit 配置 |
|
||||
| JSON Schema 校验 | `internal/http/handlers/webhook_handler.go` | 最小字段必填与 unknown field 拒绝 |
|
||||
| graceful shutdown | `internal/app/app.go` | 优雅停机 |
|
||||
|
||||
---
|
||||
|
||||
## 3. 生产一期明确排除范围
|
||||
|
||||
以下能力**不在生产一期范围内**，不作为阶段完成的阻塞项：
|
||||
|
||||
- 人工回复用户链路（人工客服 → 用户消息推送）
|
||||
- 排队位置查询
|
||||
- webhook 速率限制
|
||||
- metrics / tracing / SLO 监控面板
|
||||
- 知识库 CRUD / 发布 / 审核
|
||||
- WebSocket 实时会话
|
||||
- 多租户隔离
|
||||
- 外部系统（NewAPI/Sub2API）深度集成
|
||||
|
||||
---
|
||||
|
||||
## 4. 剩余 P0 缺口（门禁必须项）
|
||||
|
||||
在以下 P0 缺口**全部收口**前，不得将项目状态汇报为"生产一期完成"：
|
||||
|
||||
### P0-1：工单状态流转审计
|
||||
- **当前状态**：✅ 已落地，`TicketWorkflowStore` 在 Assign/Resolve/Close 时均调用 `writeAudit`
|
||||
- **代码位置**：`internal/store/postgres/ticket_workflow.go`
|
||||
- **记录内容**：before_state（隐式）/ after_state（显式）、actor_id、source_ip、action（assign/resolve/close）
|
||||
|
||||
### P0-2：安全拒绝事件审计
|
||||
- **当前状态**：✅ 已落地，`WebhookSecurity.auditReject` 在签名缺失/无效/过期/body 读取失败时均写入审计
|
||||
- **代码位置**：`internal/http/handlers/webhook_security.go`
|
||||
- **记录内容**：Type=`webhook_security_rejected`，Action=`security_reject`，error_code、path、timestamp 等信息
|
||||
|
||||
### P0-3：工单关闭语义明确
|
||||
- **当前状态**：只有 resolve，没有 close 语义
|
||||
- **要求**：工单关闭语义明确为 resolve=已解决关闭，或补充 close 接口
|
||||
- **代码位置**：`internal/http/handlers/ticket_handler.go`
|
||||
|
||||
### P0-4：Webhook 路由对齐
|
||||
- **当前状态**：已落地统一入口 `/api/v1/customer-service/webhook`
|
||||
- **INTERFACE.md 定义**：`/api/v1/customer-service/webhook/{channel}`（按渠道独立入口）
|
||||
- **当前方案**：统一入口通过 Query/Body 中的 `channel` 字段识别渠道，与 INTERFACE 定义兼容，无需路由拆分
|
||||
- **说明**：生产一期采用统一入口简化运维；如后续渠道量增加，可扩展为 `/webhook/{channel}` 路径
|
||||
|
||||

# 生产一期范围定义 vs Phase 2（接口级决策）
|
||||
|
||||
> 版本：v1.0 | 日期：2026-04-30
|
||||
> 决策人：PM（小龙团队）
|
||||
> 关联：QA_CHECKLIST.md、PRODUCTION_EXECUTION_PLAN.md、PRODUCTION_PHASE1_SCOPE.md
|
||||
|
||||
---
|
||||
|
||||
## 1. 背景
|
||||
|
||||
QA CHECKLIST.md 发现 16+ 接口与文档存在严重漂移，且错误码定义不一致。PM 需要决策每个漂移接口属于：
|
||||
- **Phase 1**：生产一期必须实现，否则阻断上线
|
||||
- **Phase 2**：可推迟到 Phase 2，不阻断当前上线
|
||||
- **废弃**：从 INTERFACE.md 中移除，不实现
|
||||
|
||||
---
|
||||
|
||||
## 2. 决策原则
|
||||
|
||||
### Phase 1 原则（按 PRIORITY 排列）
|
||||
真实持久化 > 安全审计 > 工单闭环 > 可观测 > 灰度可回滚
|
||||
|
||||
### Phase 2 原则
|
||||
- RAG/知识库运营（KB 端点）
|
||||
- 运营后台（dashboard/统计/质检）
|
||||
- 身份核验
|
||||
- 大模型 failover
|
||||
- 商业化
|
||||
|

|
||||
|
||||
## 3. 接口级决策
|
||||
|
||||
### 3.1 会话管理接口
|
||||
|
||||
| # | 接口 | 当前状态 | 决策 | 理由 |
|
||||
|---|------|----------|------|------|
|
||||
| 1 | `GET /api/v1/customer-service/tickets/{id}` — 工单详情 | ❌ 未实现 | **Phase 1** | 工单闭环必需：客服需要查询单个工单详情，assign/resolve/close 前必须能查询。运营人员需要查看工单处理历史。 |
|
||||
| 2 | `GET /api/v1/customer-service/sessions/{id}` — 会话信息 | ❌ 未实现 | **Phase 2** | 生产一期会话仅通过 webhook 消息触发转人工，会话查询不是工单闭环必需路径。Phase 2 再实现。 |
|
||||
| 3 | `GET /api/v1/customer-service/sessions/{id}/messages` — 会话消息历史 | ❌ 未实现 | **Phase 2** | 同上，会话消息历史对工单闭环非必需。Phase 2 实现，支持客服查看用户说了什么。 |
|
||||
| 4 | `POST /api/v1/customer-service/sessions/{id}/feedback` — 反馈提交 | ❌ 未实现 | **Phase 1** | 工单闭环必需：客服解决工单后需要收集用户满意度反馈，记录在审计日志中。真实持久化要求。 |
|
||||
| 5 | `POST /api/v1/customer-service/sessions/{id}/handoff` — 手动转人工 | ❌ 未实现（仅 webhook 触发） | **Phase 1** | 工单闭环必需：当前只有 webhook 意图触发自动转人工，但没有显式的手动转人工 API。客服无法主动为用户创建工单。**P0 阻断项**。 |
|
||||
|
||||
**决策说明 1-5：**
|
||||
- 已有 `GET /tickets`（列表），但缺少 `GET /tickets/{id}`（详情），客服无法查看工单详情就无法处理工单。
|
||||
- 会话查询与会话消息历史是运营视角功能，不是工单闭环核心链路，Phase 2 再做。
|
||||
- 手动转人工 handoff 是紧急需求（用户说"转人工"但系统无法识别），Phase 1 必须实现。
|
||||
- 反馈提交是工单解决的闭环动作，Phase 1 必须实现。
|
||||
|
||||
### 3.2 知识库接口（全系 7 个）
|
||||
|
||||
| # | 接口 | 当前状态 | 决策 | 理由 |
|
||||
|---|------|----------|------|------|
|
||||
| 6 | `GET /api/v1/customer-service/kb` — 列表知识库条目 | ❌ 未实现 | **Phase 2** | 知识库运营/RAG 相关，属于 Phase 2 范围。生产一期的 RAG 检索依赖预置知识库，不需要管理接口。 |
|
||||
| 7 | `POST /api/v1/customer-service/kb` — 创建条目 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
| 8 | `GET /api/v1/customer-service/kb/{id}` — 获取条目 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
| 9 | `PUT /api/v1/customer-service/kb/{id}` — 更新条目 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
| 10 | `DELETE /api/v1/customer-service/kb/{id}` — 删除条目 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
| 11 | `POST /api/v1/customer-service/kb/{id}/publish` — 发布条目 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
| 12 | `POST /api/v1/customer-service/kb/search` — 检索知识库 | ❌ 未实现 | **Phase 2** | 同上 |
|
||||
|
||||
**决策说明 6-12：**
|
||||
知识库 CRUD/发布/审核属于 Phase 2 的「RAG/知识库运营」范围。生产一期仅需要预置知识库内容能正常检索，不需要管理接口。
|
||||
|
||||
### 3.3 运营后台接口
|
||||
|
||||
| # | 接口 | 当前状态 | 决策 | 理由 |
|
||||
|---|------|----------|------|------|
|
||||
| 13 | `GET /api/v1/customer-service/admin/dashboard` — 运营大盘 | ❌ 未实现 | **Phase 2** | 属于 Phase 2「运营后台」范围。生产一期可先通过 `GET /tickets` 和数据库查询实现最小监控。 |
|
||||
| 14 | `GET /api/v1/customer-service/admin/handoff-reasons` — 转人工统计 | ❌ 未实现 | **Phase 2** | 同上，运营后台统计功能，Phase 2 再做。 |
|
||||
| 15 | `POST /api/v1/customer-service/admin/feedback-review` — 质检提交 | ❌ 未实现 | **Phase 2** | 同上，运营后台质检功能，Phase 2 再做。 |
|
||||
|
||||
**决策说明 13-15：**
|
||||
运营后台属于 Phase 2 范围。生产一期不实现，不阻断上线。
|
||||
|
||||
### 3.4 工单统计接口
|
||||
|
||||
| # | 接口 | 当前状态 | 决策 | 理由 |
|
||||
|---|------|----------|------|------|
|
||||
| 16 | `GET /api/v1/customer-service/tickets/stats` — 工单统计 | 🔄 实现中 | **Phase 1** | 可观测/灰度可回滚必需：灰度阶段需要监控转人工率、工单创建量等指标。运营人员需要实时统计数据。 |
|
||||
| 17 | 速率限制（请求频率控制） | 🔄 实现中 | **Phase 1** | 防止接口滥用，保护服务稳定性；`CS_SES_4002` 错误码对应实现。 |
|
||||
|
||||
**决策说明 16：**
|
||||
工单统计是生产一期可观测能力的最小子集，必须实现以便在灰度阶段监控核心 SLA 指标。
|
||||
|
||||

|
||||
|
||||
## 4. 错误码漂移决策
|
||||
|
||||
### 4.1 CS_TICKET_4091 vs CS_TKT_4002 不一致
|
||||
|
||||
| 文档定义 | 代码实际 | 决策 |
|
||||
|----------|----------|------|
|
||||
| `CS_TKT_4002`（工单已被分配） | `CS_TICKET_4091` | **统一为文档值 `CS_TKT_4002`** |
|
||||
|
||||
**理由**：`CS_TKT_4002` 更符合错误码命名规范（业务前缀_资源_序号）。代码中散落的 `CS_TICKET_4091` 需要统一改为 `CS_TKT_4002`。
|
||||
|
||||
**修复方案**：
|
||||
- 在 `internal/domain/error/` 包中统一定义错误码常量
|
||||
- 所有 handler 引用统一常量，不在业务代码中 hardcode 错误码
|
||||
- 废弃 `CS_TICKET_4091`，统一使用 `CS_TKT_4002`
|
||||
|
||||
### 4.2 未使用错误码归档
|
||||
|
||||
以下错误码在 INTERFACE.md 中定义，但代码中无触发路径，决策如下：
|
||||
|
||||
| 错误码 | 状态 | 决策 |
|
||||
|--------|------|------|
|
||||
| `CS_SES_4001`（会话不存在） | 未使用 | **归档 Phase 2**：Phase 1 没有 GET session/{id} 接口，无法触发此错误 |
|
||||
| `CS_SES_4002`（消息频率过高） | 未实现 | **归档 Phase 2**：速率限制未实现 |
|
||||
| `CS_SES_4003`（身份校验已锁定） | 未实现 | **归档 Phase 2**：身份核验未实现 |
|
||||
| `CS_IDT_4001`（身份信息不匹配） | 未实现 | **归档 Phase 2**：身份核验未实现 |
|
||||
| `CS_IDT_4002`（验证码错误） | 未实现 | **归档 Phase 2**：身份核验未实现 |
|
||||
| `CS_KB_4001`（知识库条目不存在） | 未实现 | **归档 Phase 2**：KB 接口 Phase 2 实现 |
|
||||
| `CS_KB_4002`（条目名称已存在） | 未实现 | **归档 Phase 2**：KB 接口 Phase 2 实现 |
|
||||
| `CS_LLM_5001`（LLM 服务不可用） | 未实现 | **归档 Phase 2**：大模型 failover 未实现 |
|
||||
| `CS_LLM_5002`（LLM 超时） | 未实现 | **归档 Phase 2**：大模型 failover 未实现 |
|
||||
| `CS_AUTH_4001`（越权访问） | 未实现 | **归档 Phase 2**：RBAC 未实现 |
|
||||
|
||||
**决策说明**：
|
||||
这些错误码是 Phase 2 功能的占位符。Phase 1 不实现这些功能，也就不需要这些错误码。Phase 2 实现时直接从 `internal/domain/error/` 包中启用。
|
||||
|
||||

|
||||
|
||||
## 5. Phase 1 真实范围总结
|
||||
|
||||
### 5.1 需实现的接口（共 6 个）
|
||||
|
||||
| # | 接口 | 优先级 | 阻断原因 |
|
||||
|---|------|--------|----------|
|
||||
| P1-A | `GET /api/v1/customer-service/tickets/{id}` | **P0** | 工单闭环必需，客服需要查看详情才能处理 |
|
||||
| P1-B | `POST /api/v1/customer-service/sessions/{id}/handoff` | **P0** | 手动转人工必需，当前只能 webhook 触发 |
|
||||
| P1-C | `POST /api/v1/customer-service/sessions/{id}/feedback` | **P0** | 工单解决后反馈收集，工单闭环必需 |
|
||||
| P1-D | `GET /api/v1/customer-service/tickets/stats` | **P1** | 可观测必需，灰度阶段监控 SLA |
|
||||
| P1-E | 错误码统一（`CS_TKT_4002`） | **P0** | 文档与代码一致性要求 |
|
||||
|
||||
### 5.2 Phase 2 归档（16 个接口 + 10 个错误码）
|
||||
|
||||
| 类别 | 接口/错误码数 | 说明 |
|
||||
|------|--------------|------|
|
||||
| 知识库 KB 全系 | 7 接口 | Phase 2 RAG/知识库运营 |
|
||||
| 运营后台 admin | 3 接口 | Phase 2 运营后台 |
|
||||
| 会话管理（查询类） | 2 接口 | Phase 2 再实现 |
|
||||
| 未使用错误码 | 10 个 | Phase 2 功能占位符 |
|
||||
|
||||
### 5.3 废弃（0 个）
|
||||
|
||||
无接口从 INTERFACE.md 中永久删除，均为 Phase 2 推迟。
|
||||
|
||||

|
||||
|
||||
## 6. Phase 1 完成标准
|
||||
|
||||

# 客服 SLA 与升级响应规范
|
||||
|
||||
> 版本：v1.0 | 状态：已生效
|
||||
> 关联：tech/INTERFACE.md、PRODUCTION_PHASE1_STATUS.md
|
||||
|
||||
---
|
||||
|
||||
## 1. 客服 SLA 定义
|
||||
|
||||
### 1.1 核心 SLA 指标
|
||||
|
||||
| 指标 | 目标值 | 说明 |
|
||||
|------|--------|------|
|
||||
| Webhook 可用率 | ≥ 99.5% | 成功接收渠道消息的比率 |
|
||||
| 首次响应时间（机器人） | ≤ 5s | 从收到消息到发出首字的时间（P95） |
|
||||
| 机器人回答准确率 | ≥ 85% | FAQ 命中且用户未点"不满意" |
|
||||
| 转人工率 | ≤ 15% | 需要人工介入的会话比例 |
|
||||
| 工单响应时间 | ≤ 30min | 从创建到客服接单的时间（P95） |
|
||||
| 工单解决时间 | ≤ 4h | 从创建到解决的时间（P95） |
|
||||
|
||||
> **注**：上述指标为生产一期目标值，实际值需在灰度阶段采集并调整基线。
|
||||
|
||||
### 1.2 SLA 优先级定义
|
||||
|
||||
| 优先级 | 定义 | 响应时间 | 解决时间 |
|
||||
|--------|------|----------|----------|
|
||||
| P1 | 机器人完全不可用（所有消息报错） | 15min | 1h |
|
||||
| P2 | 核心能力降级（签名/幂等失效、频繁 5xx） | 30min | 2h |
|
||||
| P3 | 非核心功能异常（部分渠道失败、偶发报错） | 2h | 8h |
|
||||
|
||||
---
|
||||
|
||||
## 2. 升级响应规范
|
||||
|
||||
### 2.1 升级链路
|
||||
|
||||
```
|
||||
告警/故障发现 → P3 处理（值班工程师） → 若恶化升级 P2 → 若继续恶化升级 P1
|
||||
```
|
||||
|
||||
### 2.2 告警触发条件
|
||||
|
||||
| 条件 | 级别 | 通知方式 |
|
||||
|------|------|----------|
|
||||
| Webhook 可用率 < 99% 持续 5min | P2 | 飞书群 + 电话 |
|
||||
| 错误率 > 5% 持续 5min | P2 | 飞书群 |
|
||||
| PostgreSQL 连接失败 | P1 | 电话 + 飞书群 |
|
||||
| 签名校验失败率 > 20% 持续 10min | P3 | 飞书群 |
|
||||
| 工单积压 > 50 个 open 状态 | P3 | 飞书群 |
|
||||
|
||||
> **注**：告警系统（metrics/tracing/SLO）属于 P1 缺口，**当前未落地**，告警触发依赖人工巡检。生产一期灰度阶段需补齐可观测性基础设施。
|
||||
|
||||
### 2.3 升级决策人
|
||||
|
||||
| 级别 | 第一响应人 | 升级对象 |
|
||||
|------|------------|----------|
|
||||
| P3 | 值班工程师 | Team Lead |
|
||||
| P2 | Team Lead | 技术总监 |
|
||||
| P1 | 技术总监 | 小龙/业务负责人 |
|
||||
|
||||
### 2.4 故障处理要求
|
||||
|
||||
- P1/P2 故障：故障清除后 24h 内提交故障报告
|
||||
- P3 异常：记录在运营日志，下周一回溯复盘
|
||||
- 所有故障必须在下一灰度周期前完成根因分析
|
||||
|
||||

|
||||
|
||||
## 3. 当前阶段说明
|
||||
|
||||
### 3.1 可用性现状
|
||||
|
||||
| 能力 | 当前状态 | 备注 |
|
||||
|------|----------|------|
|
||||
| Webhook 可用率监控 | 未完成 | P1 缺口，metrics/tracing 未落地 |
|
||||
| 错误率监控 | 未完成 | 同上 |
|
||||
| PostgreSQL 连接监控 | ✅ 已完成 | `/ready` 含 PostgreSQL 依赖检查 |
|
||||
| 工单积压监控 | 未完成 | 无定时任务扫描 open 工单 |
|
||||
| 安全拒绝事件审计 | ✅ 已完成 | `webhook_security.go` 的 `auditReject` 写入审计 |
|
||||
| 工单状态流转审计 | ✅ 已完成 | `TicketWorkflowStore.writeAudit` 在 assign/resolve/close 时调用 |
|
||||
|
||||
### 3.2 接口级 SLA（当前代码能力）
|
||||
|
||||
以下为代码中已实现的接口响应时间基准（本地压测数据，待灰度验证）：
|
||||
|
||||
| 接口 | 目标延迟 | 当前状态 |
|
||||
|------|----------|----------|
|
||||
| `POST /webhook` | < 200ms P99 | HMAC 校验 + 幂等检查开销约 5-10ms |
|
||||
| `GET /tickets` | < 300ms P99 | PostgreSQL 查询，无索引优化 |
|
||||
| `POST /tickets/{id}/assign` | < 200ms P99 | 单条 UPDATE |
|
||||
| `POST /tickets/{id}/resolve` | < 200ms P99 | 单条 UPDATE |
|
||||
| `GET /actuator/health` | < 50ms | 依赖 PostgreSQL |
|
||||
|
||||
> **注**：当前压测数据为本地单实例，未经过真实渠道流量验证。
|
||||
|
||||
---
|
||||
|
||||
## 4. 错误码与 SLA 映射
|
||||
|
||||
错误码定义见 `tech/INTERFACE.md`，与 SLA 相关联的快速参考：
|
||||
|
||||
| 错误码 | 含义 | SLA 影响 |
|
||||
|--------|------|----------|
|
||||
| `CS_SES_4001` | 会话不存在 | 返回 404，用户可重试 |
|
||||
| `CS_SES_4002` | 消息频率过高 | 返回 429，触发限流逻辑 |
|
||||
| `CS_TKT_4001` | 工单不存在 | 返回 404 |
|
||||
| `CS_TKT_4002` | 工单已被分配 | 返回 409，幂等性保证 |
|
||||
| `CS_LLM_5001` | LLM 服务不可用 | 触发转人工，SLA 降级 |
|
||||
| `CS_LLM_5002` | LLM 超时 | 同上 |
|
||||
|
||||
---
|
||||
|
||||
## 5. 持续改进
|
||||
|
||||
SLA 基线在灰度第一周期（建议 2 周）后复盘，根据真实数据调整：
|
||||
- 若机器人响应时间 P95 > 5s，需优化 LLM 调用链路
|
||||
- 若转人工率 > 20%，需复盘意图识别准确率
|
||||
- 若工单解决时间 P95 > 4h，需增加客服人力或优化分流策略
|
||||
|
||||

# 工单运营闭环 SOP
|
||||
|
||||
> 版本：v1.0 | 状态：已生效
|
||||
> 关联：tech/INTERFACE.md、PRODUCTION_PHASE1_STATUS.md
|
||||
|
||||
---
|
||||
|
||||
## 1. 工单生命周期
|
||||
|
||||
```
|
||||
用户触发转人工
|
||||
→ [待落地] 工单创建（含排队位置）
|
||||
→ 客服接单（assign）
|
||||
→ 客服处理
|
||||
→ 客服解决（resolve）
|
||||
→ [待明确] 工单关闭（close？）
|
||||
→ 用户满意度反馈（可选）
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 2. 各状态定义
|
||||
|
||||
| 状态 | 含义 | 触发条件 | 当前是否落地 |
|
||||
|------|------|----------|--------------|
|
||||
| `open` | 待接单 | 转人工触发工单创建 | ✅ 已落地 |
|
||||
| `assigned` | 已分配 | 客服主动接单或系统分配 | ✅ 已落地 |
|
||||
| `resolved` | 已解决 | 客服处理完毕 | ✅ 已落地 |
|
||||
| `closed` | 已关闭 | 显式调用 close 接口 | ✅ 已落地（`TicketWorkflowStore.Close`） |
|
||||
|
||||
---
|
||||
|
||||
## 3. 触发转人工的条件
|
||||
|
||||
### 3.1 自动转人工（系统触发）
|
||||
|
||||
以下意图识别结果会**自动创建工单**（代码：`internal/service/dialog/service.go`）：
|
||||
|
||||
- 退款请求（intent = refund / 退款）
|
||||
- 敏感内容（intent.sensitive = true）
|
||||
|
||||
### 3.2 手动转人工
|
||||
|
||||
- 用户发送"人工客服"、"转人工"等关键词（需 RAG 识别后触发）
|
||||
- 会话 turnCount 超过阈值（待实现）
|
||||
|
||||
---
|
||||
|
||||
## 4. 工单创建流程
|
||||
|
||||
### 4.1 当前已落地（最小闭环）
|
||||
|
||||
**接口**：`POST /api/v1/customer-service/sessions/{session_id}/handoff`
|
||||
|
||||
**代码**：`internal/service/dialog/service.go` → `handoff_service.CreateTicket`
|
||||
|
||||
**流程**：
|
||||
1. 对话服务检测到需要转人工
|
||||
2. 创建 ticket 记录（session_id, user_id, priority, handoff_reason）
|
||||
3. ticket 状态 = `open`
|
||||
4. 触发审计日志写入
|
||||
|
||||
**缺失项**：
|
||||
- 工单创建时**未记录上下文快照**（`context_snapshot` 字段为空）
|
||||
- 排队位置**未实现**（用户无法查询前面还有多少人）
|
||||
- 工单创建**未主动通知**客服（无消息推送链路）
|
||||
|
||||
### 4.2 待落地项
|
||||
|
||||
| 缺失项 | 优先级 | 说明 |
|
||||
|--------|--------|------|
|
||||
| 工单创建时上下文快照 | P0 | 用于客服接手时了解会话历史 |
|
||||
| 排队位置查询 API | P1 | `GET /tickets/queue-position` |
|
||||
| 客服新工单通知 | P1 | 飞书/邮件/站内信通知 |
|
||||
| 客服回复用户链路 | P1 | 人工消息推送回用户 |
|
||||
|
||||
---
|
||||
|
||||
## 5. 工单分配流程
|
||||
|
||||
### 5.1 已落地
|
||||
|
||||
**接口**：`POST /api/v1/customer-service/tickets/{id}/assign?agent_id={agent_id}`
|
||||
|
||||
**代码**：`internal/http/handlers/ticket_handler.go` → `POST /tickets/{id}/assign`
|
||||
|
||||
**流程**：
|
||||
1. 客服调用 assign 接口
|
||||
2. 更新 ticket.status = `assigned`，ticket.assigned_to = agent_id
|
||||
3. 写入审计日志（✅ 已落地：调用 `TicketWorkflowStore.writeAudit`）
|
||||
|
||||
**缺失项**：
|
||||
- 工单状态流转审计 ✅ 已落地（`TicketWorkflowStore.writeAudit` 在 assign 时调用）
|
||||
|
||||
---
|
||||
|
||||
## 6. 工单解决流程
|
||||
|
||||
### 6.1 已落地
|
||||
|
||||
**接口**：`POST /api/v1/customer-service/tickets/{id}/resolve?resolution={resolution}`
|
||||
|
||||
**流程**：
|
||||
1. 客服处理完毕后调用 resolve
|
||||
2. 更新 ticket.status = `resolved`，ticket.resolution = resolution
|
||||
3. 写入审计日志（✅ 已落地：调用 `TicketWorkflowStore.writeAudit`）
|
||||
|
||||
**缺失项**：
|
||||
- 工单状态流转审计 ✅ 已落地（`TicketWorkflowStore.writeAudit` 在 resolve 时调用）
|
||||
|
||||
---
|
||||
|
||||
## 7. 工单关闭流程
|
||||
|
||||
### 7.1 当前状态
|
||||
|
||||
**已落地**：`TicketWorkflowStore.Close` 接口已实现，支持显式关闭工单。
|
||||
|
||||
**语义定义**：
|
||||
- `resolve` = 客服确认问题已解决，工单进入 `resolved` 状态
|
||||
- `close` = 工单正式关闭，进入 `closed` 状态（resolved 后可选调用）
|
||||
- 已解决工单（resolved）可直接 close；未解决工单也可强制 close
|
||||
|
||||
---
|
||||
|
||||
## 8. 客服工作台操作规范（API 层）
|
||||
|
||||
### 8.1 班次开始
|
||||
|
||||
1. 调用 `GET /api/v1/customer-service/tickets?status=open` 查看当前待接单工单
|
||||
2. 按 priority（ P1 > P2 > P3）和创建时间排序
|
||||
|
||||
### 8.2 接单
|
||||
|
||||
```bash
|
||||
curl -X POST "https://{host}/api/v1/customer-service/tickets/{ticket_id}/assign?agent_id={agent_id}"
|
||||
```
|
||||
|
||||
成功后工单状态变为 `assigned`
|
||||
|
||||
### 8.3 处理与解决
|
||||
|
||||
```bash
|
||||
curl -X POST "https://{host}/api/v1/customer-service/tickets/{ticket_id}/resolve?resolution={解决说明}"
|
||||
```
|
||||
|
||||
### 8.4 工单列表查询
|
||||
|
||||
```bash
|
||||
# 查看所有 open 工单
|
||||
curl "https://{host}/api/v1/customer-service/tickets?status=open"
|
||||
|
||||
# 查看指定客服的工单
|
||||
curl "https://{host}/api/v1/customer-service/tickets?assigned_to={agent_id}"
|
||||
|
||||
# 查看统计
|
||||
curl "https://{host}/api/v1/customer-service/tickets/stats"
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 9. 用户侧体验
|
||||
|
||||
### 9.1 转人工后用户感知
|
||||
|
||||
**当前已落地**：用户发送敏感/退款意图 → 收到机器人回复"已为您转接人工客服，请稍候"
|

|
||||
|
||||
### 异常处理
|
||||
|
||||
- [ ] 工单 assign 后长时间（> 2h）未 resolve → 系统告警（待实现）/ 人工巡检
|
||||
- [ ] 同一用户连续创建 > 3 个 open 工单 → 异常标记，人工复核
|
||||
- [ ] 工单创建失败（服务异常） → 降级：保留内存记录 → 恢复后补录

|
||||
|
||||
---
|
||||
|
||||
## 2. 核心能力对标
|
||||
|
||||
### 2.1 平台公告系统（Sub2API）
|
||||
|
||||
Sub2API 的公告系统是当前竞品中最接近客服沟通的能力，其设计值得借鉴：
|
||||
|
||||
**数据模型**:
|
||||
```go
|
||||
type Announcement struct {
|
||||
ent.Schema
|
||||
}
|
||||
// Fields:
|
||||
// title — 公告标题（200字）
|
||||
// content — 内容（Markdown，text 类型）
|
||||
// status — draft / active / archived
|
||||
// notify_mode — silent(仅铃铛) / popup(弹窗)
|
||||
// targeting — 展示条件（JSONB 规则）
|
||||
// starts_at — 开始时间
|
||||
// ends_at — 结束时间
|
||||
// created_by — 管理员ID
|
||||
// reads — 已读记录关联
|
||||
```
|
||||
|
||||
**关键设计细节**:
|
||||
- **状态机**: draft → active → archived，支持预发布审核
|
||||
- **通知模式**: 静默模式（仅显示红点）vs 弹窗模式（强制届到）
|
||||
- **定向规则**: JSONB 存储展示条件，支持按用户群体定向
|
||||
- **排期管理**: starts_at / ends_at 支持时间窗控制
|
||||
- **已读跟踪**: `AnnouncementRead` 关联表，记录每个用户的阅读状态
|
||||
- **索引优化**: status, created_at, starts_at, ends_at 均有索引
|
||||
|
||||
**公告阅读流程**:
|
||||
```
|
||||
用户登录 → 查询有效公告列表
|
||||
→ 应用 targeting 规则过滤
|
||||
→ 检查已读状态
|
||||
→ 弹窗/铃铛通知
|
||||
→ 用户阅读 → 写入 AnnouncementRead
|
||||
```
|
||||
|
||||
### 2.2 用户与订阅体系（Sub2API）
|
||||
|
||||
Sub2API 提供了完整的用户身份与使用情况查询能力，这是客服系统的基础数据来源：
|
||||
|
||||
- `User`: 基础用户信息
|
||||
- `UserSubscription`: 订阅计划、配额、到期时间
|
||||
- `UsageLog`: 详细用量记录（模型、token 数、成本、时间戳）
|
||||
- `ApiKey`: 用户 API Key 管理
|
||||
- `PromoCode` / `RedeemCode`: 营销代码
|
||||
|
||||
**用户分组与权限**:
|
||||
- `Group`: 用户分组
|
||||
- `UserAllowedGroup`: 用户-分组关联
|
||||
- `AccountGroup`: 上游账号分组
|
||||
|
||||
### 2.3 用户反馈（NewAPI/OneAPI 基础功能）
|
||||
|
||||
NewAPI/OneAPI 提供基础的工单/反馈功能：
|
||||
- 用户可提交问题反馈
|
||||
- 管理员可回复
|
||||
- 状态跟踪（待处理/处理中/已解决）
|
||||
- 缺乏 AI 自动回复和知识库支持
|
||||

||||
|
||||
---
|
||||
|
||||
## 5. 对技术规划的影响
|
||||
|
||||
### 应引入的设计模式
|
||||
|
||||
| 设计模式 | 来源 | 应用场景 |
|
||||
|---------|------|---------|
|
||||
| **公告状态机** | Sub2API | 客服公告/通知的发布流程管理 |
|
||||
| **通知模式** | Sub2API | 静默 vs 弹窗的分级触达 |
|
||||
| **Targeting 规则** | Sub2API | 按用户群体、渠道、版本号定向推送 |
|
||||
| **已读跟踪** | Sub2API | 通知透达率统计 |
|
||||
| **用户-订阅-用量关联** | Sub2API | 客服场景下的用户信息快速查询 |
|
||||
| **工单状态机** | NewAPI | 问题跟踪与处理流程 |
|
||||
|
||||
### 技术避坑
|
||||
|
||||
1. **知识库选型**: Sub2API 的 PRD 建议在 TechLead 前完成 Milvus/Qdrant/PGVector 的 POC，验证中文检索延迟 < 200ms。竞品分析建议优先考虑 PGVector（与 PostgreSQL 集成，减少运维复杂度），次之 Qdrant（轻量级），最后 Milvus（大规模场景）。
|
||||
2. **对话上下文存储**: 需要设计高效的对话上下文管理机制，支持长对话上下文的截断与摘要。
|
||||
3. **多渠道适配层**: 每个渠道（Telegram/Discord/微信）都有独特的消息格式和限制，需要适配层抽象。
|
||||
4. **LLM 容灾设计**: 必须设计主备模型 + 降级方案，避免单点故障。

|
||||
## 四、市场定位结论
|
||||
|
||||
### 4.1 竞品空白
|
||||
|
||||
**Intercom/Zendesk/Drift 等通用客服方案：**
|
||||
- 面向电商/在线客服场景
|
||||
- 对"API Key 配置/模型路由/Token 消耗/错误码诊断"等开发者问题支持极弱
|
||||
- 价格高（$55-74+/seat/月），中小企业负担重
|
||||
|
||||
**Dify/FastGPT 等开源方案：**
|
||||
- LLM 应用平台，需要二次开发才能成为客服产品
|
||||
- 缺乏工单系统、多渠道接入、知识库管理后台等完整能力
|
||||
- 开发者友好但运维成本高
|
||||
|
||||
**竞品不提供（立连桥独有）：**
|
||||
1. 对接 `platform-token-runtime` 查询用户真实 Token 消耗
|
||||
2. 对接 `supply-api` 查询供应商账号状态
|
||||
3. 最近 5 条错误日志诊断
|
||||
4. 开发者友好的代码示例/错误码解释
|
||||
|
||||
### 4.2 ai-customer-service 差异化定位
|
||||
|
||||
```
|
||||
通用客服（Intercom/Zendesk）
|
||||
└─ 场景：电商/在线客服
|
||||
└─ 价格：$55-74+/seat/月
|
||||
└─ 开发者场景：❌ 不支持 API Key/Token/错误码
|
||||
|
||||
开源方案（Dify/FastGPT）
|
||||
└─ 场景：LLM 应用平台
|
||||
└─ 价格：免费
|
||||
└─ 完整客服能力：❌ 需二次开发
|
||||
|
||||
───────────────────────────────────
|
||||
立连桥 ai-customer-service = 开发者 API 客服
|
||||
✅ 对接真实用户数据（Token/配额/错误日志）
|
||||
✅ 多渠道（Widget/Telegram/Discord/微信）
|
||||
✅ 工单系统 + 知识库管理
|
||||
✅ 模型 failover（OpenAI + Claude 双备）
|
||||
✅ 价格：内部成本（低成本替代 Intercom）
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 五、关键技术差异
|
||||
|
||||
### 5.1 多渠道接入对比
|
||||
|
||||
| 方案 | 渠道覆盖 | 接入复杂度 | 统一管理 |
|
||||
|------|---------|----------|--------|
|
||||
| Intercom Fin | Web/FB/WhatsApp | 低（SaaS） | ✅ |
|
||||
| Zendesk | 全渠道 | 低（SaaS） | ✅ |
|
||||
| Dify | 需开发 | 高 | ⚠️ |
|
||||
| **ai-customer-service** | Widget/TG/Discord/微信 | 中 | ✅ |
|
||||
|
||||
### 5.2 开发者场景深度对比
|
||||
|
||||
| 方案 | API Key 核验 | Token 消耗查询 | 错误日志诊断 | 代码示例回复 |
|
||||

|
||||
| Zendesk | ❌ | ❌ | ❌ | ⚠️ 通用 |
|
||||
| **ai-customer-service** | ✅ | ✅ | ✅ | ✅ |
|
||||
|
||||

|
||||
|
||||
## 六、技术选型建议
|
||||
|
||||
| 组件 | 推荐方案 | 理由 |
|
||||
|------|---------|------|
|
||||
| 向量数据库 | Qdrant | P99 延迟 <200ms，Rust 实现性能好，部署简单 |
|
||||
| 对话历史存储 | PostgreSQL | 持久化需求强，工单关联 |
|
||||
| 模型供应商 | OpenAI + Claude 双备 | 质量+覆盖率平衡 |
|
||||
| 多渠道接入 | 统一消息总线 | 减少耦合，channel 层薄 |
|
||||
| RAG 策略 | sentence embedding + keyword 混合 | 中文语义检索质量+关键词兜底 |

|------|------|-----|-----|
|
||||
| 主库故障 | 自动切换至备库 | < 5 min | < 1 min |
|
||||
| 逻辑损坏 | 从备库恢复 + 审计日志回放 | < 30 min | < 1 min |
|
||||
|
||||
### 4.2 应用层灾备
|
||||
|
||||
| 场景 | 处理 |
|
||||
|------|------|
|
||||
| API Server 单机故障 | 负载均衡自动移除，剩余节点继续服务 |
|
||||
| LLM 主供应商故障 | 5 秒内切换至备用供应商 |
|
||||
| 双 LLM 故障 | 返回兑底回复 + 自动生成工单 |
|
||||
| Redis 故障 | 会话状态丢失，用户需要重新发起会话（接受） |
|
||||
| 向量数据库故障 | 知识库检索降级为关键词匹配，不影响核心对话 |
|
||||
| 数据库连接池耗尽 | 进入降级模式：仅返回静态 FAQ 链接 |
|
||||
|
||||
### 4.3 多中心部署
|
||||
|
||||
- 当前阶段为单中心部署。
|
||||
- 未来扩展至多中心时，需要解决 PostgreSQL 分布式写入、Redis 主从同步和 WebSocket 连接的跨中心问题。

|
||||
## 1. 设计目标与约束
|
||||
|
||||
### 1.1 核心目标
|
||||
|
||||
| 指标 | 基准值 | 目标值 | 验证方式 |
|
||||
|------|--------|--------|---------|
|
||||
| 人工客服介入率 | 100% | ≤ 40% | 转人工工单数 / 总会话数 |
|
||||
| 首次响应时间 | 人工排班时段 | ≤ 10 秒 | 用户消息到达至首次回复的 P99 |
|
||||
| 常见问题一次解决率 | 0 | ≥ 75% | 用户标记已解决 / (总会话 - 明确转人工) |
|
||||
| 用户满意度 CSAT | 无 | ≥ 4.0 / 5.0 | 每周抽样调查 |
|
||||
| 系统可用性 | 无 | ≥ 99.5% | 健康检查通过率 7 天滑动窗口 |
|
||||
|
||||
### 1.2 技术约束（强制性）
|
||||
|
||||
- **语言**: Go 1.22+
|
||||
- **HTTP 框架**: 标准库 `net/http` + 自定义中间件（禁止引入 Gin/Echo）
|
||||
- **数据库**: PostgreSQL 15+ ，驱动 `jackc/pgx/v5`
|
||||
- **缓存**: Redis，客户端 `redis/go-redis/v9`
|
||||
- **配置**: YAML + Viper，环境变量覆盖敏感字段
|
||||
- **日志/审计**: 结构化日志，审计事件模型与 supply-api/ 一致
|
||||
- **错误码**: `{SOURCE}_{CATEGORY}_{CODE}` 格式，例如 `CS_SES_4001`
|
||||
- **健康检查**: `/actuator/health` 、 `/actuator/health/live` 、 `/actuator/health/ready`
|
||||
- **测试**: Go testing + testify，覆盖率门槛 domain ≥ 70%、service/handler ≥ 80%
|
||||
|
||||
### 1.3 运行模式
|
||||
|
||||
本系统必须同时支持两种运行模式：
|
||||
|
||||
| 模式 | 特征 | 部署方式 | 适用场景 |
|
||||
|------|------|---------|---------|
|
||||
| **独立运行** | 自有 `cmd/ai-customer-service/main.go`，独立数据库 schema，独立 docker-compose | `docker-compose up` 或单独容器 | 外部用户只需要客服能力 |
|
||||
| **集成运行** | 作为 Go module 被 `gateway/` 引入，共享数据库连接池和配置 | 编译时作为子模块编译，运行时挂载到 gateway 主进程 | 立交桥用户希望获得一体化客服能力 |
|
||||
|
||||
**集成约束**:
|
||||
- 独立运行时，系统必须提供完整的 HTTP API 、Webhook 接入和运营后台。
|
||||
- 集成运行时，系统必须提供 `IntegrationPlugin` 接口，允许主程序通过配置开关启用/禁用各模块。
|
||||
- 数据库 schema 必须使用独立的 `cs_` 前缀，避免与主项目表名冲突。
|
||||
- 配置文件必须支持分离加载：独立运行时读取自己的 `config.yaml`，集成运行时合并到主项目配置。

## 3. 核心模块设计
|
||||
|
||||
### 3.1 渠道适配器 (Channel Adapter)
|
||||
|
||||
#### 3.1.1 设计目标
|
||||
封装 Telegram、Discord、微信、网页 Widget 的消息格式差异，对内部提供统一的 `UnifiedMessage` 结构。
|
||||
|
||||
#### 3.1.2 核心结构
|
||||
|
||||
```go
|
||||
type UnifiedMessage struct {
|
||||
MessageID string // 渠道原生消息 ID
|
||||
Channel string // telegram | discord | wechat | widget
|
||||
OpenID string // 渠道用户唯一标识
|
||||
UserID string // 立交桥账户 ID（已绑定时）
|
||||
Content string // 消息内容（已过滤）
|
||||
ContentType string // text | image | file | voice
|
||||
Timestamp time.Time
|
||||
ReplyTo string // 回复的消息 ID
|
||||
}
|
||||
|
||||
type ChannelAdapter interface {
|
||||
ParseWebhook(r *http.Request) (*UnifiedMessage, error)
|
||||
SendReply(ctx context.Context, msg *UnifiedMessage, reply string) error
|
||||
ValidateWebhook(r *http.Request) error // 验证 Webhook 签名
|
||||
ChannelType() string
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.1.3 渠道特定处理
|
||||
|
||||
| 渠道 | 接入方式 | 特殊处理 |
|
||||
|------|---------|---------|
|
||||
| Telegram | Webhook / 长连接 | 支持 Markdown 格式，消息长度限制 4096 字符 |
|
||||
| Discord | Webhook / Bot API | 支持 Embed 格式，速率限制 5 次/秒 |
|
||||
| 微信 | 客服消息 Webhook | 需要签名验证，回复时间窗口 48 小时 |
|
||||
| Widget | WebSocket / SSE | 支持实时打字效果，跨域配置 CORS |
|
||||
|
||||
#### 3.1.4 消息过滤与安全
|
||||
- 图片、文件、语音类消息直接返回 "暂不支持该类型消息"，不解析、不存储。
|
||||
- 内容长度 > 2000 字符时，截断至 2000 字符并提示。
|
||||
|
||||
### 3.2 对话引擎 (Dialog Engine)
|
||||
|
||||
#### 3.2.1 会话状态机
|
||||
|
||||
```
|
||||
├── idle (空闲)─────────────────────────┐
|
||||
│ │ │
|
||||
│ 新消息 │ 超时30分钟
|
||||
│ ↓ ↓
|
||||
├── processing (处理中)──────────────────┘
|
||||
│ │
|
||||
│ 处理完成 │
|
||||
│ ↓
|
||||
├── waiting_feedback (等待用户反馈)───────────┐
|
||||
│ │ │
|
||||
│ 解决/未解决 │ 超时30分钟
|
||||
│ │ ↓
|
||||
│ ↓ closed (关闭)
|
||||
├── handoff (已转人工)────────────────────────┘
|
||||
│ │
|
||||
│ 工单关闭 → closed
|
||||
┘
|
||||
```
|
||||
|
||||
#### 3.2.2 上下文管理
|
||||
- 每个会话保留最近 5 轮对话（用户 5 条 + 机器人 5 条 = 10 条）。
|
||||
- 超出部分从 Redis List 中自动清理，不再参与 LLM 上下文。
|
||||
- 会话超时 30 分钟无消息则自动关闭。
|
||||
|
||||
#### 3.2.3 处理流程
|
||||
|
||||
```
|
||||
1. 接收 UnifiedMessage
|
||||
2. 身份校验：已绑定→提取 UserID；未绑定→请求邮箱/前缀校验
|
||||
3. 意图识别：LLM 输出 [意图, 置信度, 实体]
|
||||
4. 判断：
|
||||
a. 敏感意图（退款/封禁/安全）→ 直接转人工（P1 工单）
|
||||
b. 用户明确要求人工 → 转人工
|
||||
c. 置信度 < 0.60 → 转人工
|
||||
d. 其他 → 知识库检索 + LLM 生成回复
|
||||
5. 回复用户，等待反馈
|
||||
6. 用户反馈 "已解决" → 会话关闭
|
||||
7. 用户反馈 "未解决" → 计算轮次，超过 3 轮 → 转人工
|
||||
```
|
||||
|
||||
### 3.3 意图识别 (Intent Engine)
|
||||
|
||||
#### 3.3.1 意图分类
|
||||
|
||||
| 意图类别 | 示例 | 置信度阈值 | 处理方式 |
|
||||
|---------|------|-----------|---------|
|
||||
| api_key_management | "怎么生成 API Key" | ≥ 0.85 | 知识库 + 操作指引 |
|
||||
| quota_query | "我的配额还剩多少" | ≥ 0.85 | 知识库 + 诊断查询 |
|
||||
| model_routing | "怎么配置模型路由" | ≥ 0.85 | 知识库 + 代码示例 |
|
||||
| error_debug | "返回 429 是什么意思" | ≥ 0.85 | 知识库 + 错误码释义 |
|
||||
| billing | "怎么开发票" | ≥ 0.85 | 知识库 + 流程链接 |
|
||||
| sensitive_refund | "我要申请退款" | ≥ 0.70 | **强制转人工** |
|
||||
| sensitive_ban | "我的账户被封了" | ≥ 0.70 | **强制转人工** |
|
||||
| sensitive_security | "我的数据泄露了" | ≥ 0.70 | **强制转人工** |
|
||||
| handoff_request | "找人工、投诉" | ≥ 0.90 | **强制转人工** |
|
||||
| unknown | 无法分类 | < 0.60 | 转人工 |
|
||||
|
||||
#### 3.3.2 LLM 调用提示词策略
|
||||
|
||||
```
|
||||
系统 Prompt 结构：
|
||||
1. 角色："你是立交桥平台的智能客服助手，仅回答与立交桥相关的问题。"
|
||||
2. 范围限制："不要回答与立交桥无关的问题。不要提供内部系统架构、密钥、服务器地址等敏感信息。"
|
||||
3. 数据隔离："仅使用当前用户的数据进行查询。如果用户未提供身份信息，不能查询任何个人数据。"
|
||||
4. 输出格式：JSON，含 intent、confidence、entities、needs_human、sensitive 字段
|
||||
```
|
||||
|
||||
#### 3.3.3 Failover 策略
|
||||
- 主模型超时 5 秒 → 切换备用模型供应商。
|
||||
- 备用模型也超时 5 秒 → 返回兑底回复 + 自动生成工单。
|
||||
- 兑底回复不依赖大模型，为静态模板："当前咨询量较大，请稍后或提交工单由人工处理。"
|
||||
|
||||
### 3.4 RAG 知识库引擎
|
||||
|
||||
#### 3.4.1 索引管理
|
||||
- 知识库条目使用 Markdown 格式，分块后通过嵌入模型生成向量。
|
||||
- 向量存储于向量数据库（Milvus / Qdrant / PGVector），检索延迟 P99 < 200ms。
|
||||
- 新条目发布后 30 秒内生效（异步重新索引）。
|
||||
|
||||
#### 3.4.2 检索流程
|
||||
```
|
||||
1. 用户问题 → 嵌入模型生成查询向量
|
||||
2. 向量数据库 Top-K 检索（K=5）
|
||||
3. 重排序：基于相关性 + 条目引用次数 + 最近更新时间
|
||||
4. 取 Top-3 作为上下文片段
|
||||
5. 拼接到 LLM Prompt 中生成回复
|
||||
```
|
||||
|
||||
#### 3.4.3 知识库缺失处理
|
||||
- 检索无结果且意图置信度 < 0.60 → 直接转人工。
|
||||
- 记录 "知识库未命中" 事件，每日汇总给运营团队。
|
||||
|
||||
### 3.5 诊断服务 (Diagnosis Service)
|
||||
|
||||
#### 3.5.1 只读查询范围
|
||||
|
||||
| 查询类型 | 调用方 | 超时 | 失败处理 |
|
||||
|---------|--------|------|---------|
|
||||
| 用户身份校验 | supply-api/ 内部接口 | 2s | 请求邮箱二次校验 |
|
||||
| 配额查询 | token-runtime/ 内部接口 | 2s | 回复通用说明，提示稍后重试 |
|
||||
| Token 消耗 | token-runtime/ 内部接口 | 2s | 同上 |
|
||||
| 最近错误日志 | supply-api/ 内部接口 | 3s | 回复通用排查步骤 |
|
||||
|
||||
#### 3.5.2 安全限制
|
||||
- 所有查询必须携带当前会话的 user_id，系统不允许跨用户查询。
|
||||
- API Key 前缀匹配时，若匹配到多个账户，请求邮箱二次校验；仍无法确定则转人工。
|
||||
- 错误的 API Key 或密码不记录，仅记录失败次数与事件类型。
|
||||
|
||||
### 3.6 转人工机制 (Handoff Service)
|
||||
|
||||
#### 3.6.1 转人工触发条件（任意满足即触发）
|
||||
|
||||
| 条件 | 工单优先级 | 备注 |
|
||||
|------|-----------|------|
|
||||
| 意图置信度 < 0.60 | P2 | 标记原因：意图不明 |
|
||||
| 用户发送“人工客服”等关键词 | P2 | 标记原因：用户要求 |
|
||||
| 敏感意图（退款/封禁/安全） | P1 | 标记原因：敏感问题 |
|
||||
| 身份校验失败累计 3 次 | P2 | 标记原因：身份失败 |
|
||||
| 多轮对话未解决（> 3 轮） | P2 | 标记原因：未解决 |
|
||||
| 主备模型均故障 | P1 | 标记原因：模型故障 |
|
||||
|
||||
#### 3.6.2 工单分配逻辑
|
||||
- 未处理工单按优先级（P1 > P2 > P3）与时间升序排列。
|
||||
- 客服点击“接收”后，工单状态在 1 秒内变更为 “处理中”并锁定为该客服。
|
||||
- 排队超过 15 分钟向用户发送排队进度通知。
|
||||
|
||||
### 3.7 知识库管理 (Knowledge Base Service)
|
||||
|
||||
#### 3.7.1 条目结构
|
||||
|
||||
```go
|
||||
type KBEntry struct {
|
||||
ID string // UUID
|
||||
Title string // 标题
|
||||
Content string // Markdown 内容
|
||||
Category string // api_key | quota | billing | routing | error_code | onboarding | other
|
||||
Tags []string // 标签
|
||||
ReferenceCount int // 被引用次数

|
||||
CreatedAt time.Time
|
||||
UpdatedAt time.Time
|
||||
Version int // 乐观锁
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.7.2 更新机制
|
||||
- 运营后台增删改查条目，点击“发布”后 30 秒内生效。
|
||||
- 产品文档变更时，知识库更新为发布 checklist 项。
|
||||
- 每周生成知识库未命中报告，驱动文档补充。
|
||||
|
||||

|
||||
|
||||
## 5. 关键流程设计
|
||||
|
||||
### 5.1 用户问题自助解决流程
|
||||
|
||||
```
|
||||
用户发送消息

Auth/Identity Service 身份校验
|
||||
↓
|
||||
Dialog Manager 检查会话状态，更新上下文
|
||||
↓
|
||||
Intent Engine 识别意图 + 置信度
|
||||
↓
|
||||
是否敏感/人工/低置信度？
|
||||
│──是 → Handoff Service 生成工单 → 通知用户排队/等待
|
||||
↓否
|
||||
RAG Engine 检索知识库
|
||||
↓
|
||||
需要用户数据？
|
||||
│──是 → Diagnosis Service 查询只读 API
|
||||
↓否
|
||||
LLM Client 生成回复
|
||||
↓
|
||||
Channel Adapter 发送回复
|
||||
↓
|
||||
等待用户反馈（30 min 超时关闭）
|
||||
```
|
||||
|
||||
### 5.2 转人工流程
|
||||
|
||||
```
|
||||
触发条件满足
|
||||
↓
|
||||
Dialog Manager 更新会话状态 → handoff
|
||||
↓
|
||||
Ticket Service 创建工单（含会话上下文快照）
|
||||
↓
|
||||
Audit Service 记录 handoff 事件
|
||||
↓
|
||||
通知渠道：用户收到排队/等待提示
|
||||
↓
|
||||
客服后台：工单入队列
|
||||
↓
|
||||
客服接收 → 状态变更为 processing
|
||||
↓
|
||||
客服解决 → 状态变更为 resolved → 关闭会话
|
||||
```
|
||||
|
||||
### 5.3 大模型故障 Failover 流程
|
||||
|
||||
```
|
||||
LLM Client 调用主模型
|
||||
↓
|
||||
超时 5 秒
|
||||
↓
|
||||
切换至备用模型
|
||||
↓
|
||||
超时 5 秒
|
||||
↓
|
||||
返回兑底回复 + 自动生成工单
|
||||
↓
|
||||
Monitor Service 记录 failover 事件并触发告警
|
||||
```

## 6. 技术选型理由及备选方案
|
||||
|
||||
| 技术点 | 选型 | 理由 | 备选方案 |
|
||||
|--------|------|------|---------|
|
||||
| HTTP 框架 | 标准库 net/http | 与 gateway/ 、supply-api/ 一致，避免框架依赖 | 无 |
|
||||
| 数据库 | PostgreSQL 15+ | 与主项目一致，支持 JSONB 和向量扩展 | 无 |
|
||||
| 向量数据库 | PGVector | 无需额外部署，与 PostgreSQL 共存，支持中文语义检索 | Milvus (高性能、分布式) / Qdrant (轻量、Cloud-native) |
|
||||
| LLM 供应商 | 主：OpenAI GPT-4o；备：阿里云通义千问 | 中英文理解能力强，API 稳定，备用保障国内访问 | Claude / 火山引擎 |
|
||||
| 嵌入模型 | OpenAI text-embedding-3-small | 成本低、效果好，与 LLM 供应商一致 | 中文嵌入模型（如 BGE） |
|
||||
| 缓存 | Redis | 与主项目一致，支持会话、频率限制 | 无 |
|
||||
| 消息队列 | 内部 Go channel + worker pool | 足够支撑当前并发，避免额外依赖 | Kafka (未来高并发) |
|
||||
| 向量索引更新 | 异步 worker | 知识库变更不频繁，异步更新足够 | 无 |
|
||||
|

|
||||
|
||||
## 7. 与立交桥主系统的集成点
|
||||
|
||||
### 7.1 Gateway 集成
|
||||
|
||||
| 集成点 | 接口形式 | 说明 |
|
||||
|--------|---------|------|
|
||||
| 消息接入 | Webhook POST /api/v1/customer-service/webhook/{channel} | Gateway 将渠道消息转发至客服系统 |
|
||||
| 消息回复 | HTTP POST 回调 | 客服系统调用 Gateway 消息发送接口 |
|
||||
| 状态查询 | GET /actuator/health | Gateway 健康检查，不健康时跳过客服路由 |
|
||||
|
||||
### 7.2 platform-token-runtime 集成
|
||||
|
||||
| 集成点 | 接口形式 | 说明 |
|
||||
|--------|---------|------|
|
||||
| 配额查询 | 内部 gRPC / HTTP 只读接口 | 延迟 < 500ms，带 user_id 校验 |
|
||||
| Token 消耗查询 | 内部 gRPC / HTTP 只读接口 | 延迟 < 500ms |
|
||||
| 错误日志查询 | 内部 gRPC / HTTP 只读接口 | 返回最近 5 条 |
|
||||
|
||||
### 7.3 supply-api 集成
|
||||
|
||||
| 集成点 | 接口形式 | 说明 |
|
||||
|--------|---------|------|
|
||||
| 用户身份校验 | 内部 gRPC / HTTP 只读接口 | API Key 前缀匹配、邮箱验证 |
|
||||
| 审计日志格式 | 约定 | 与 supply-api/ 审计规范一致 |
|
||||
|
||||
### 7.4 NewAPI / Sub2API 集成
|
||||
|
||||
| 集成点 | 接口形式 | 说明 |
|
||||
|--------|---------|------|
|
||||
| Webhook 接入 | 标准化 POST 接口 | NewAPI/Sub2API 可配置将用户消息转发至本系统 |
|
||||
| 工单推送 | REST API 或 Webhook 回调 | NewAPI/Sub2API 可定期获取待处理工单状态 |
|
||||
| 知识库共享 | REST API 查询 | NewAPI/Sub2API 可消费知识库数据 |
|
||||
| 适配层 | Adapter 接口 | 独立部署时通过配置指定对方 Webhook 地址和鉴权信息 |
|
||||
|
||||
---
|
||||
|
||||
## 8. 安全设计
|
||||
|
||||
### 8.1 数据保护
|
||||
- 客服系统 **仅拥有只读查询权限**。任何写操作（修改配额、重置密码、删除用户）必须通过工单由人工授权后执行。
|
||||
- 用户数据查询必须携带当前会话的 user_id，系统不允许跨用户查询。
|
||||
- API Key 前缀匹配时不存储完整 API Key。
|
||||
- 错误的身份信息不记录，仅记录失败次数。
|
||||
|
||||
### 8.2 审计日志
|
||||
- 所有会话创建、转人工、工单状态变更、知识库变更均需记录审计事件。
|
||||
- 审计事件与 supply-api/ 保持一致的结构和存储方式。
|
||||
- 保留期 ≥ 90 天。
|
||||
|
||||
### 8.3 越权防护
|
||||
- 运营后台基于 RBAC，角色：`cs:agent`（客服）、`cs:admin`（运营管理）。
|
||||
- 客服系统接口调用 supply-api / token-runtime 时使用内部服务账户，不使用用户凭证。
|
||||
- 内部服务账户仅拥有只读权限。
|
||||
|
||||
### 8.4 Prompt Injection 防护
|
||||
- 系统 Prompt 中明确禁止回复非当前用户数据、禁止提供内部系统架构或密钥。
|
||||
- 定期红队测试（每月一次），检验 Prompt Injection 防护效果。
|
||||
- 敏感操作意图（退款/封禁/安全）强制转人工，不走 LLM 生成回复流程。
|
||||

## 10. 风险评估与缓解策略
|
||||
|
||||
| 风险编号 | 风险描述 | 概率 | 影响 | 缓解策略 |
|
||||
|---------|---------|------|------|---------|
|
||||
| R-1 | LLM 幻觉导致错误指导用户配置 | 中 | 高 | 1. 回答范围限制在知识库内容；2. 涉及操作必须附带官方文档链接；3. 每日抽样 5% 对话质检；4. 高风险意图强制转人工 |
|
||||
| R-2 | 用户通过 Prompt Injection 泄露敏感数据 | 中 | 高 | 1. 系统 Prompt 明确禁止；2. user_id 强制校验；3. 全量安全审计日志；4. 定期红队测试 |
|
||||

|
||||
|
||||
### 10.1 威胁建模
|
||||
|
||||
| 威胁场景 | 攻击路径 | 影响 | 控制措施 | 验证要求 |
|
||||
|---------|---------|------|---------|---------|
|
||||
| Prompt Injection 绕过安全边界 | 用户输入恶意提示词诱导模型泄露内部信息或跨会话数据 | 敏感信息泄露、错误操作建议 | System Prompt 禁止输出内部信息；敏感意图强制转人工；会话级 user_id 强绑定；响应输出增加敏感词审计 | 红队注入样例每月回归；高风险样例必须稳定拒绝 |
|
||||
| 渠道伪造 Webhook | 外部伪造渠道回调向系统注入假消息/假工单 | 工单污染、审计失真 | 渠道签名校验、时间戳窗口校验、幂等键、防重放 nonce | 每个渠道提供签名失败/重放攻击测试用例 |
|
||||
| 运营后台越权查询 | 客服/运营绕过 RBAC 查看非授权会话和工单 | 用户隐私泄露 | RBAC + 资源级过滤；后端强制按 user_id / workspace 过滤；审计查询行为 | QA 必测跨用户/跨角色访问 403 |
|
||||
| Adapter 调用外部只读 API 失控 | 诊断查询未限流导致压垮 supply-api / token-runtime | 上游链路抖动、级联故障 | 限流、超时、熔断、降级静态 FAQ/排障链接 | 压测和故障注入时验证 fail-open/fail-closed 策略 |
|
||||
| 审计日志篡改或缺失 | 工单/转人工/知识库变更未留痕或被覆盖 | 无法追责、无法回放 | 审计事件单独写入；不可变追加；失败重试队列；90 天保留 | 审计写入失败必须告警且阻断高风险操作 |
|
||||
|
||||
### 10.2 设计阶段门控结论
|
||||
|
||||
**结论：REQUEST_CHANGES（补齐实现与验证门禁后，方可进入开发）**
|
||||
|
||||
**放行前必须满足：**
|
||||
- HLD 中所有关键能力都能映射到真实实现落点：渠道接入、意图识别、RAG、转人工、工单、审计、监控。
|
||||
- TechLead 任务拆解必须继续细化到文件/函数级，确保 Engineer 不会在实现阶段自行改架构。
|
||||
- QA 必须基于本 HLD 补充调用链检查点：定义 → 装配 → 调用 → 入口。
|
||||
- 运行模式、OpenAPI、IntegrationPlugin、NewAPI/Sub2API 适配要求均需在后续实现验证中列为阻断项。
|
||||
|
||||
**阻断条件：**
|
||||
- 任一高风险链路（Webhook 鉴权、越权访问、审计留痕、降级策略）未提供可执行验证方案。
|
||||
- 任一关键能力只有接口声明没有真实挂载入口。
|
||||
- 无法证明独立运行与集成运行两种模式都可交付。
|
||||
|
||||

|
||||
|
||||
## 11. 技术栈与集成约束
|
||||
|
||||
### 11.1 统一技术栈
|
||||
本项目必须与立交桥主项目保持一致：
|
||||
- **语言**: Go 1.22+
|
||||
- **HTTP框架**: 标准库 `net/http` + 自定义中间件（禁止引入 Gin/Echo 等第三方框架，保持与 gateway/ 和 supply-api/ 的一致性）
|
||||
- **数据库**: PostgreSQL 15+ ，驱动 `jackc/pgx/v5`
|
||||
- **缓存**: Redis，客户端 `redis/go-redis/v9`
|
||||
- **配置**: YAML + Viper，环境变量覆盖敏感字段
|
||||
- **日志/审计**: 结构化日志，审计事件模型与 supply-api/ 一致
|
||||
- **错误码**: `{SOURCE}_{CATEGORY}_{CODE}` 格式，例如 `CS_SES_4001`
|
||||
- **健康检查**: `/actuator/health` 、 `/actuator/health/live` 、 `/actuator/health/ready`
|
||||
- **测试**: Go testing + testify，覆盖率门槛 domain ≥ 70%、service/handler ≥ 80%
|
||||
|
||||
### 11.2 独立运行与集成运行
|
||||
本系统必须同时支持两种运行模式：
|
||||
|
||||
| 模式 | 特征 | 部署方式 | 适用场景 |
|
||||
|------|------|---------|---------|
|
||||
| **独立运行** | 自有 `cmd/ai-customer-service/main.go`，独立数据库 schema，独立 docker-compose | `docker-compose up` 或单独容器 | 外部用户只需要客服能力，不想接入立交桥全套 |
|
||||
| **集成运行** | 作为 Go module 被 `gateway/` 引入，共享数据库连接池和配置，通过内部接口注册 | 编译时作为子模块编译，运行时挂载到 gateway 主进程 | 立交桥用户希望获得一体化客服能力 |
|
||||
|
||||
**集成约束**:
|
||||
- 独立运行时，系统必须提供完整的 HTTP API、Webhook 接入和运营后台。
|
||||
- 集成运行时，系统必须提供 `IntegrationPlugin` 接口，允许主程序通过配置开关启用/禁用各模块。
|
||||
- 数据库 schema 必须使用独立的 `cs_` 前缀，避免与主项目表名冲突。
|
||||
- 配置文件必须支持分离加载：独立运行时读取自己的 `config.yaml`，集成运行时合并到主项目配置。
|
||||
|
||||
### 11.3 NewAPI / Sub2API 适配支持
|
||||
本系统的核心能力必须能够对接 NewAPI 和 Sub2API 系统：
|
||||
- **Webhook 接入**: 提供标准化的 Webhook 接口，NewAPI/Sub2API 可配置将用户消息转发至本系统。
|
||||
- **工单推送**: 提供标准化工单接口，NewAPI/Sub2API 可定期获取待处理工单状态。
|
||||
- **知识库共享**: 提供知识库查询接口，NewAPI/Sub2API 可消费此数据补充自己的帮助文档。
|
||||
- **独立部署时**: 通过配置文件指定 NewAPI/Sub2API 的 Webhook 地址和鉴权信息，本系统通过适配层（Adapter）与之交互。
|
||||
- **集成部署时**: 若立交桥 gateway/ 已接入 NewAPI/Sub2API，本系统通过 gateway/ 的内部路由接口接入客服能力。
|
||||
|
||||
### 11.4 对外接口契约
|
||||
- 必须提供 OpenAPI 3.0 接口文档，确保 NewAPI/Sub2API 开发者可以独立接入。
|
||||
- 接口路径前缀默认为 `/api/v1/customer-service/`，集成运行时可通过配置改为 `/internal/customer-service/`。

## 1. 生产数据模型与 Migration 方案
|
||||
|
||||
### 1.1 当前 Schema 评估
|
||||
|
||||
现有 `0001_init.up.sql` 已覆盖核心表，但缺少以下生产必填字段和表：
|
||||
|
||||
#### 缺口 1：`cs_sessions.tenant_id` 缺失
|
||||
生产环境必须支持多租户，`cs_sessions` / `cs_tickets` / `cs_audit_logs` 均需 `tenant_id`。
|
||||
- **修复方案**：新增 migration `0002_add_tenant_id.up.sql`
|
||||
- **影响**：必须向后兼容，现有数据 default 为 `'default'`
|
||||
|
||||
#### 缺口 2：`cs_tickets.assigned_at` 缺失
|
||||
工单分配时间用于 SLA 计算和排队位置查询。
|
||||
- **修复方案**：新增 `assigned_at TIMESTAMPTZ` 字段
|
||||
|
||||
#### 缺口 3：`cs_tickets.status` 缺少 `'pending'` 状态
|
||||
当前仅 `open/assigned/processing/resolved/closed`，但客服接单前应有 `pending` 过渡状态。
|
||||
- **HLD 漂移检测**：INTERFACE.md 定义的状态机无 `pending`，但运营场景需要"排队中"状态
|
||||
- **建议**：将现有 `open` 重语义为 `pending`，另起 `assigned` 为"已分配"
|
||||
|
||||
#### 缺口 4：缺少 `cs_agent_sessions` 和 `cs_agent_stats` 表
|
||||
HLD 3.8.X/3.8.Y 定义了这两个表用于客服统计，当前不存在。
|
||||
- **修复方案**：新增 migration `0003_add_agent_tables.up.sql`
|
||||
|
||||
#### 缺口 5：缺少 `cs_channel_bindings` 表
|
||||
HLD 4.2.5 定义了渠道绑定表，当前未实现。
|
||||
|
||||
### 1.2 Migration 命名规范
|
||||
|
||||
```
|
||||
db/migration/
|
||||
├── 0001_init.up.sql # 已有
|
||||
├── 0002_add_tenant_id.up.sql # TechLead: 新增
|
||||
├── 0003_add_agent_tables.up.sql
|
||||
├── 0004_add_ticket_fields.up.sql
|
||||
└── 0005_add_channel_bindings.up.sql
|
||||
```
|
||||
|
||||
### 1.3 具体 Migration 设计
|
||||
|
||||
#### `0002_add_tenant_id.up.sql`
|
||||
```sql
|
||||
ALTER TABLE cs_sessions ADD COLUMN tenant_id VARCHAR(64) NOT NULL DEFAULT 'default';
|
||||
ALTER TABLE cs_tickets ADD COLUMN tenant_id VARCHAR(64) NOT NULL DEFAULT 'default';
|
||||
ALTER TABLE cs_audit_logs ADD COLUMN tenant_id VARCHAR(64) NOT NULL DEFAULT 'default';
|
||||
|
||||
CREATE INDEX IF NOT EXISTS idx_sessions_tenant ON cs_sessions(tenant_id, status);
|
||||
CREATE INDEX IF NOT EXISTS idx_tickets_tenant ON cs_tickets(tenant_id, status, priority);
|
||||
-- 回滚：ALTER TABLE DROP COLUMN tenant_id CASCADE（注意与现有 FK 冲突检测）
|
||||
```
|
||||
|
||||
#### `0003_add_agent_tables.up.sql`
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS cs_agent_sessions (
|
||||
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
agent_id VARCHAR(64) NOT NULL,
|
||||
ticket_id UUID NOT NULL REFERENCES cs_tickets(id) ON DELETE CASCADE,
|
||||
joined_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
|
||||
left_at TIMESTAMPTZ NULL
|
||||
);
|
||||
|
||||
CREATE TABLE IF NOT EXISTS cs_agent_stats (
|
||||
id BIGSERIAL PRIMARY KEY,
|
||||
agent_id VARCHAR(64) NOT NULL,
|
||||
date DATE NOT NULL,
|
||||
tickets_handled INT DEFAULT 0,
|
||||
avg_handle_time_sec INT DEFAULT 0,
|
||||
handoff_count INT DEFAULT 0,
|
||||
csat_score DECIMAL(3,2) NULL,
|
||||
UNIQUE(agent_id, date)
|
||||
);
|
||||
```
|
||||
|
||||
#### `0004_add_ticket_fields.up.sql`
|
||||
```sql
|
||||
ALTER TABLE cs_tickets ADD COLUMN assigned_at TIMESTAMPTZ NULL;
|
||||
ALTER TABLE cs_tickets ALTER COLUMN status TYPE VARCHAR(16);
|
||||
-- 将 status CHECK 更新（见下节状态机设计）
|
||||
```
|
||||
|
||||
#### `0005_add_channel_bindings.up.sql`
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS cs_channel_bindings (
|
||||
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
channel VARCHAR(16) NOT NULL,
|
||||
open_id VARCHAR(128) NOT NULL,
|
||||
user_id VARCHAR(64) NOT NULL,
|
||||
bound_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
|
||||
bound_method VARCHAR(16) NOT NULL,
|
||||
UNIQUE(channel, open_id)
|
||||
);
|
||||
CREATE INDEX IF NOT EXISTS idx_bindings_user ON cs_channel_bindings(user_id);
|
||||
```
|
||||
|
||||
### 1.4 状态机修正（Close vs Resolve 语义）
|
||||
|
||||
当前实现将 `resolve` 和 `close` 作为两个独立 API，语义混淆。
|
||||
|
||||
**修正语义：**
|
||||
- `resolve`：客服提交处理结果，状态 → `resolved`，可继续补充 resolution
|
||||
- `close`：工单正式结单，状态 → `closed`，不可再修改
|
||||
- API 设计：`POST /tickets/{id}/resolve`（提交结果），`POST /tickets/{id}/close`（结单）
|
||||
|
||||
**迁移路径**：
|
||||
1. 当前 `resolved_at` 字段保留，`resolved` 仍为中间状态
|
||||
2. 运营后台在 resolve 后可选择 close 或让系统自动 close（需决策）
|
||||
3. 会话状态机：Handoff → `open` → `assigned` → `processing` → `resolved` → `closed`
|
||||
|
||||
**需要 TechLead 决策**：`resolved` 状态是否需要人工 close 才能关闭，还是系统自动 close？建议 resolve 后允许用户评价结单，评价后系统自动 close。

|
||||
## 2. Webhook 签名、防重放、幂等、审计 Fail-Closed 方案
|
||||
|
||||
### 2.1 当前状态评估
|
||||
|
||||
| 能力 | 当前实现 | 评估 |
|
||||
|------|---------|------|
|
||||
| 签名校验 | `webhook_security.go` HMAC-SHA256 | ✅ 已实现 |
|
||||
| 时间戳防重放 | skew 校验（无 nonce 持久化） | ⚠️ 仅 skew，无真正防重放 |
|
||||
| 幂等去重 | `dedup_store.go` 已有 | ✅ 基本实现 |
|
||||
| 安全拒绝审计 | `webhook_security.auditReject` | ⚠️ 已调用但 `Audit` 可能为 nil |
|
||||
| 失败 Body 审计 | `webhook_handler.auditRejectedRequest` | ✅ 已实现 |
|
||||
|
||||
### 2.2 签名校验当前问题
|
||||
|
||||
**问题 1**：`WebhookSecurity` 的 `Audit` 字段在 `app.go` 中已正确传入 `audits`（即 `AuditStore`），但 `AuditRecorder` 接口为 nil-check 调用，属于**部分 fail-closed**（代码存在但不保证所有路径都记录）。
|
||||
|
||||
**问题 2**：`webhook_handler.go` 的 `auditRejectedRequest` 在 `handle()` 中所有拒绝路径都被调用，包括非法 JSON、字段缺失、内容超长，**这部分已正确实现**。
|
||||
|
||||
**问题 3**：`WebhookSecurity.auditReject` 在签名失败时写入 `webhook_security_rejected` 类型，`WebhookHandler.auditRejectedRequest` 写入 `webhook_rejected` 类型，**存在重复但互补**。
|
||||
|
||||
### 2.3 防重放方案升级
|
||||
|
||||
当前时间戳 skew 校验不足以防止 replay 攻击（攻击者在有效窗口内重放旧消息）。
|
||||
|
||||
**修复方案：在 Redis/DB 中持久化 nonce**
|
||||
|
||||
```go
|
||||
// internal/store/postgres/nonce_store.go
|
||||
type NonceStore struct {
|
||||
db *sql.DB
|
||||
}
|
||||
|
||||
// NonceKey returns the redis key for a given channel+nonce.
|
||||
// Uses Postgres if Redis unavailable (同步写入，TTL 自动清理).
|
||||
func (s *NonceStore) TryUse(ctx context.Context, channel, nonce string, ttl time.Duration) (bool, error) {
|
||||
// INSERT ... ON CONFLICT DO NOTHING，TTL 通过 PostgreSQL 定期清理任务实现
|
||||
_, err := s.db.ExecContext(ctx, `
|
||||
INSERT INTO cs_webhook_nonces (channel, nonce, used_at)
|
||||
VALUES ($1, $2, NOW())
|
||||
ON CONFLICT (channel, nonce) DO NOTHING`)
|
||||
if err != nil {
|
||||
return false, err
|
||||
}
|
||||
// PostgreSQL 没有 TTL 支持，改为每日清理：
|
||||
// DELETE FROM cs_webhook_nonces WHERE used_at < NOW() - INTERVAL '1 day'
|
||||
return true, nil
|
||||
}
|
||||
```
|
||||
|
||||
**Migration**:
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS cs_webhook_nonces (
|
||||
channel VARCHAR(16) NOT NULL,
|
||||
nonce VARCHAR(128) NOT NULL,
|
||||
used_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
|
||||
PRIMARY KEY (channel, nonce)
|
||||
);
|
||||
CREATE INDEX idx_nonces_cleanup ON cs_webhook_nonces(used_at);
|
||||
```
|
||||
|
||||
### 2.4 幂等语义澄清
|
||||
|
||||
当前幂等键为 `(channel, message_id)`，但：
|
||||
1. 不同渠道可能出现相同 `message_id` → 需要 `(channel, provider_id, message_id)` 三元组
|
||||
2. `message_id` 为空时跳过幂等检查（内部消息或测试流量）
|
||||
|
||||
**修复方案**：扩展 `cs_message_dedup` 主键为 `(channel, provider, message_id)`。
|
||||
|
||||
### 2.5 安全拒绝审计 fail-closed 确认
|
||||
|
||||
审计失败时整体请求应该返回 500，当前实现仅 `log.Error` 后继续。需要确认 fail-closed 策略：
|
||||
- **当前行为**（签名失败时）：写审计失败 → 仍返回 403 → 这是正确的 fail-closed（响应失败但审计可选）
|
||||
- **高风险操作**（工单状态变更时）：审计失败必须返回 500
|
||||
|
||||
**需要决策**：ticket assign/resolve 审计写入失败是否应该回滚状态变更？建议设为可配置，紧急情况下允许 fail-open。
|
||||

|
||||
|
||||
## 3. Ticket / Session / Audit / KB 真实架构
|
||||
|
||||
### 3.1 Session 状态机缺口
|
||||
|
||||
**问题**：`domain/session/session.go` 缺少 `StatusWaitingFeedback`（HLD 定义为等待用户反馈状态）。
|
||||
|
||||
当前会话状态：`idle/processing/handoff/closed`，缺少 `waiting_feedback`。
|
||||
|
||||
**修复方案**：
|
||||
```go
|
||||
// domain/session/session.go
|
||||
const (
|
||||
StatusIdle Status = "idle"
|
||||
StatusProcessing Status = "processing"
|
||||
StatusWaitingFeedback Status = "waiting_feedback" // 新增
|
||||
StatusHandoff Status = "handoff"
|
||||
StatusClosed Status = "closed"
|
||||
)
|
||||
```
|
||||
|
||||
**对应 SQL**（需更新 migration）：
|
||||
```sql
|
||||
ALTER TABLE cs_sessions DROP CONSTRAINT chk_cs_sessions_status;
|
||||
ALTER TABLE cs_sessions ADD CONSTRAINT chk_cs_sessions_status
|
||||
CHECK (status IN ('idle','processing','waiting_feedback','handoff','closed'));
|
||||
```
|
||||
|
||||
### 3.2 排队位置查询接口设计（P1-3）
|
||||
|
||||
HLD 未定义排队位置查询接口，需要 TechLead 设计。
|
||||
|
||||
**API 设计**：
|
||||
```
|
||||
GET /api/v1/customer-service/tickets/queue-position?ticket_id={id}
|
||||
Response: {
|
||||
"ticket_id": "xxx",
|
||||
"position": 3,
|
||||
"estimated_wait_minutes": 15,
|
||||
"ahead_count": 2,
|
||||
"priority": "P2"
|
||||
}
|
||||
```
|
||||
|
||||
**实现逻辑**：
|
||||
```go
|
||||
// internal/http/handlers/queue_handler.go
|
||||
func (h *QueueHandler) GetPosition(w http.ResponseWriter, r *http.Request) {
|
||||
ticketID := r.URL.Query().Get("ticket_id")
|
||||
ticket, err := h.ticketStore.GetByID(r.Context(), ticketID)
|
||||
if err != nil {
|
||||
writeJSON(w, http.StatusNotFound, map[string]any{...})
|
||||
return
|
||||
}
|
||||
position, err := h.ticketStore.GetQueuePosition(r.Context(), ticket)
|
||||
// position = count of open tickets with higher priority, then same priority older
|
||||
writeJSON(w, http.StatusOK, map[string]any{
|
||||
"ticket_id": ticketID,
|
||||
"position": position,
|
||||
"estimated_wait_minutes": position * 5, // P2 平均处理时间 5 分钟
|
||||
"priority": ticket.Priority,
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### 3.3 Audit 与 Ticket 联动
|
||||
|
||||
**当前问题**：`ticket_workflow.go` 的 `writeAudit` 是静默失败（仅 log.Error），不符合 fail-closed。
|
||||
|
||||
**修复方案**：将 `writeAudit` 改为返回 error，由调用方决定是否回滚：
|
||||
```go
|
||||
func (s *TicketWorkflowStore) Assign(...) error {
|
||||
// ... DB update ...
|
||||
if err := s.writeAudit(ctx, ...); err != nil {
|
||||
// 回滚已更新的 DB 状态
|
||||
s.db.ExecContext(ctx, "UPDATE cs_tickets SET ... WHERE id = $1", ...)
|
||||
return fmt.Errorf("audit failed: %w", err)
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
### 3.4 KB 真实架构（当前为内存实现）
|
||||
|
||||
**当前状态**：`store/memory/knowledge_store.go` 存在，无持久化。
|
||||
|
||||
**生产缺口**：无 PostgreSQL schema 支持 KB。
|
||||
- 需要新增 `cs_kb_entries` 的 PG 持久化 store
|
||||
- 需要向量索引方案（当前无 embedding 接入）
|
||||
|
||||
---
|
||||
|
||||
## 4. IntegrationPlugin / 集成运行模式设计
|
||||
|
||||
### 4.1 当前状态
|
||||
|
||||
当前 `app.go` 的 `New()` 即为独立运行入口，无 IntegrationPlugin 接口。
|
||||
`PRODUCTION_EXECUTION_PLAN.md` 要求提供 `IntegrationPlugin` 接口支持集成运行。
|
||||
|
||||
### 4.2 IntegrationPlugin 接口设计
|
||||
|
||||
```go
|
||||
// internal/plugin/plugin.go
|
||||
package plugin
|
||||
|
||||
// IntegrationPlugin 是 ai-customer-service 作为 Go module 被主程序引入时暴露的接口。
|
||||
type IntegrationPlugin interface {
|
||||
// Name 返回插件名称
|
||||
Name() string
|
||||
// Init 在插件加载时调用，传入主程序共享的配置
|
||||
Init(cfg *IntegrationConfig) error
|
||||
// RegisterRoutes 将客服系统的 HTTP 路由注册到主程序 mux
|
||||
RegisterRoutes(mux *http.ServeMux) error
|
||||
// HealthCheck 返回插件级健康状态
|
||||
HealthCheck(ctx context.Context) error
|
||||
}
|
||||
|
||||
// IntegrationConfig 由主程序在插件初始化时注入
|
||||
type IntegrationConfig struct {
|
||||
DB *sql.DB // 主程序数据库连接（可选，不传则用独立 Postgres）
|
||||
Redis *redis.Client // 主程序 Redis 连接（可选）
|
||||
Logger *slog.Logger // 主程序共享 Logger
|
||||
BasePath string // 路由前缀，默认 /api/v1/customer-service
|
||||
WebhookSecret string // Webhook 签名密钥
|
||||
RegisterMetrics func(metrics.Registry) // 指标注册回调
|
||||
RegisterTracing func(tracer trace.Tracer) // tracing 注册回调
|
||||
}
|
||||
|
||||
// 实现一个 stub 以支持独立运行
|
||||
type StandalonePlugin struct{}
|
||||
func (StandalonePlugin) Name() string { return "ai-customer-service" }
|
||||
func (p *StandalonePlugin) Init(cfg *IntegrationConfig) error { /* 独立模式，使用内置 db/redis */ return nil }
|
||||
func (p *StandalonePlugin) RegisterRoutes(mux *http.ServeMux) error {
|
||||
// 使用 NewRouter 挂载完整路由
|
||||
return nil
|
||||
}
|
||||
func (p *StandalonePlugin) HealthCheck(ctx context.Context) error { return nil }
|
||||
```
|
||||
|
||||
### 4.3 独立运行 vs 集成运行配置差异
|
||||
|
||||
| 组件 | 独立运行 | 集成运行 |
|
||||
|------|---------|---------|
|
||||
| DB | 使用自己的 PostgreSQL (`AI_CS_POSTGRES_*` env) | 复用主程序 `*IntegrationConfig.DB` |
|
||||
| Redis | 独立实例 | 复用主程序 `*IntegrationConfig.Redis` |
|
||||
| Config | 从 `config.yaml` / env 加载 | 合并到主程序配置 |
|
||||
| 路由 | `/api/v1/customer-service/*` | 可配置 `BasePath` |
|
||||
| Health | 自己的 `/actuator/health` | 通过 `IntegrationPlugin.HealthCheck()` 暴露 |
|
||||
|
||||
### 4.4 入口函数设计
|
||||
|
||||
```go
|
||||
// cmd/standalone/main.go（独立运行）
|
||||
func main() {
|
||||
plugin := &StandalonePlugin{}
|
||||
// 加载配置后运行独立 HTTP 服务器
|
||||
}
|
||||
|
||||
// internal/plugin/standalone.go
|
||||
package plugin
|
||||
func RunStandalone() error {
|
||||
cfg, _ := config.Load()
|
||||
app, _ := app.New(cfg, logger)
|
||||
// 启动 HTTP 服务器
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 5. Metrics / Tracing / Logging / Health Readiness 设计
|
||||
|
||||
### 5.1 当前状态
|
||||
|
||||
- **Health**: ✅ 已实现 `/actuator/health/live/ready`，依赖 PostgreSQL
|
||||
- **Logging**: ⚠️ 仅部分结构化日志，未使用 slog 的完整上下文
|
||||
- **Metrics**: ❌ 未实现
|
||||
- **Tracing**: ❌ 未实现
|
||||
|
||||
### 5.2 Metrics 接入方案
|
||||
|
||||
**选型**：使用 Prometheus Go client + OpenTelemetry 融合方案（与主项目对齐）
|
||||
|
||||
```go
|
||||
// internal/platform/metrics/metrics.go
|
||||
package metrics
|
||||
|
||||
import (
|
||||
"github.com/prometheus/client_golang/prometheus"
|
||||
"github.com/prometheus/client_golang/prometheus/promauto"
|
||||
)
|
||||
|
||||
var (
|
||||
// 请求指标
|
||||
HTTPRequestsTotal = promauto.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "cs_http_requests_total", Help: "Total HTTP requests"},
|
||||
[]string{"method", "path", "status"},
|
||||
)
|
||||
HTTPRequestDuration = promauto.NewHistogramVec(
|
||||
prometheus.HistogramOpts{Name: "cs_http_request_duration_seconds", Buckets: []float64{.01, .05, .1, .5, 1, 5}},
|
||||
[]string{"method", "path"},
|
||||
)
|
||||
// 业务指标
|
||||
MessagesProcessedTotal = promauto.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "cs_messages_processed_total", Help: "Total messages processed"},
|
||||
[]string{"channel", "intent", "handoff"},
|
||||
)
|
||||
TicketCreatedTotal = promauto.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "cs_ticket_created_total", Help: "Total tickets created"},
|
||||
[]string{"priority", "handoff_reason"},
|
||||
)
|
||||
TicketStateTransitionsTotal = promauto.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "cs_ticket_state_transitions_total", Help: "Total ticket state transitions"},
|
||||
[]string{"from_state", "to_state"},
|
||||
)
|
||||
SessionActiveGauge = promauto.NewGauge(
|
||||
prometheus.GaugeOpts{Name: "cs_sessions_active", Help: "Current active sessions"},
|
||||
)
|
||||
LLMCallDuration = promauto.NewHistogramVec(
|
||||
prometheus.HistogramOpts{Name: "cs_llm_call_duration_seconds", Buckets: []float64{0.5, 1, 2, 5, 10}},
|
||||
[]string{"provider", "model"},
|
||||
)
|
||||
WebhookRejectedTotal = promauto.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "cs_webhook_rejected_total", Help: "Total rejected webhooks"},
|
||||
[]string{"reason_code"},
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
**在 router 中间件埋点**：
|
||||
```go
|
||||
// internal/http/middleware/metrics.go
|
||||
func MetricsMiddleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// 记录 latency 和 status code
|
||||
})
|
||||
}
|
||||
|
||||
// 暴露 /metrics 端点
|
||||
mux.Handle("/metrics", promhttp.Handler())
|
||||
```
|
||||
|
||||
### 5.3 Tracing 接入方案（OpenTelemetry）
|
||||
|
||||
```go
|
||||
// internal/platform/tracing/tracing.go
|
||||
package tracing
|
||||
|
||||
import (
|
||||
"go.opentelemetry.io/otel"
|
||||
"go.opentelemetry.io/otel/attribute"
|
||||
"go.opentelemetry.io/otel/exporters/stdout/stdouttrace"
|
||||
"go.opentelemetry.io/otel/sdk/trace"
|
||||
)
|
||||
|
||||
func Init(serviceName string) (func(), error) {
|
||||
exporter, _ := stdouttrace.New(stdouttrace.WithPrettyPrint())
|
||||
tp := trace.NewTracerProvider(
|
||||
trace.WithBatcher(exporter),
|
||||
trace.WithResource(resource.NewWithAttributes(...)),
|
||||
)
|
||||
otel.SetTracerProvider(tp)
|
||||
return func() { tp.Shutdown(context.Background()) }, nil
|
||||
}
|
||||
```
|
||||
|
||||
**在 webhook handler 中埋点**：
|
||||
```go
|
||||
// 在 dialog.Process 前后加上 span
|
||||
span := tracer.StartSpan("webhook.process")
|
||||
defer span.End()
|
||||
span.SetAttributes("channel", msg.Channel, "open_id", msg.OpenID)
|
||||
```
|
||||
|
||||
### 5.4 Structured Logging 增强
|
||||
|
||||
当前 `internal/platform/logging/logger.go` 需要支持更多字段：
|
||||
|
||||
```go
|
||||
// 日志字段规范（与 supply-api 对齐）
|
||||
log.Info("webhook received",
|
||||
"trace_id", traceID,
|
||||
"channel", msg.Channel,
|
||||
"open_id", msg.OpenID,
|
||||
"session_id", result.SessionID,
|
||||
"intent", result.Intent.Intent,
|
||||
"handoff", result.Handoff.ShouldHandoff,
|
||||
"ticket_id", result.TicketID,
|
||||
"latency_ms", latency.Milliseconds(),
|
||||
)
|
||||
```
|
||||
|
||||
### 5.5 Health Readiness 增强
|
||||
|
||||
当前 readiness 仅检查 PostgreSQL，需要扩展为多依赖检查：
|
||||
|
||||
```go
|
||||
// internal/platform/health/dependency.go
|
||||
type DependencyChecker struct {
|
||||
checks []Checker
|
||||
}
|
||||
|
||||
func (dc *DependencyChecker) Add(name string, check func(context.Context) error) {
|
||||
dc.checks = append(dc.checks, simpleCheck{name, check})
|
||||
}
|
||||
|
||||
// 在 app.go 中注册：
|
||||
checkers := []health.Checker{
|
||||
pgstore.NewDBChecker(db),
|
||||
// 新增 Redis checker
|
||||
// 新增 LLM supplier health checker
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. 降级、熔断、回滚、灰度技术方案
|
||||
|
||||
### 6.1 降级（Degradation）策略
|
||||
|
||||
| 级别 | 触发条件 | 降级行为 |
|
||||
|------|---------|---------|
|
||||
| L1 | LLM 超时 / 不可用 | 切换备用模型（2家供应商 failover） |
|
||||
| L2 | 主备模型均不可用 | 返回兑底文案（静态模板）+ 自动创建 P1 工单 |
|
||||
| L3 | 知识库不可用 | 跳过 RAG，直接用通用 LLM 提示词回复 |
|
||||
| L4 | PostgreSQL 不可用 | 仅内存模式（工单仅内存），拒绝新 webhook 写入 |
|
||||
| L5 | 完全不可用 | `/actuator/health/ready` 返回 DOWN，负载均衡摘除 |
|
||||
|
||||
**代码层面**：
|
||||
```go
|
||||
// internal/service/llm/fallback.go
|
||||
type LLMFallback struct {
|
||||
providers []LLMProvider
|
||||
idx int
|
||||
mu sync.RWMutex
|
||||
}
|
||||
|
||||
func (f *LLMFallback) Generate(ctx context.Context, prompt string) (*Response, error) {
|
||||
for i := 0; i < len(f.providers); i++ {
|
||||
resp, err := f.providers[f.idx].Generate(ctx, prompt)
|
||||
if err == nil {
|
||||
return resp, nil
|
||||
}
|
||||
f.mu.Lock()
|
||||
f.idx = (f.idx + 1) % len(f.providers)
|
||||
f.mu.Unlock()
|
||||
metrics.LLMFallbackTotal.Inc()
|
||||
}
|
||||
return nil, ErrAllProvidersFailed
|
||||
}
|
||||
```
|
||||
|
||||
### 6.2 熔断（Circuit Breaker）
|
||||
|
||||
```go
|
||||
// internal/platform/breaker/breaker.go
|
||||
type CircuitBreaker struct {
|
||||
failures int
|
||||
threshold int
|
||||
state atomic.Int32 // 0=closed, 1=half-open, 2=open
|
||||
resetAt time.Time
|
||||
}
|
||||
|
||||
// 当 external API（supply-api / token-runtime）调用失败率 > 50% 在 10s 窗口内时：
|
||||
// 打开熔断器，10s 内直接返回降级响应，不发请求
|
||||
// 10s 后进入 half-open，放行 1 个请求试探
|
||||
```
|
||||
|
||||
### 6.3 回滚（Rollback）方案
|
||||
|
||||
**数据层回滚**：
|
||||
- 使用 `db/migration/*.down.sql` 进行 schema 回滚
|
||||
- 关键数据变更使用 migration 的事务包装，失败自动回滚
|
||||
|
||||
**应用层回滚**：
|
||||
- Docker 镜像版本 tag（如 `v1.0.0` → `v1.0.1` → `v1.1.0`）
|
||||
- Kubernetes rollback：`kubectl rollout undo deployment/ai-customer-service`
|
||||
- 配置变更：保留旧配置快照，支持环境变量热覆盖
|
||||
|
||||
**回滚触发条件**：
|
||||
- 5xx 错误率 > 5% 持续 2 分钟
|
||||
- P99 延迟 > 30s 持续 5 分钟
|
||||
- 审计日志写入失败率 > 1%
|
||||
|
||||
### 6.4 灰度（Gated Rollout）方案
|
||||
|
||||
**策略 1：按渠道灰度**
|
||||
```yaml
|
||||
# config.yaml
|
||||
rollout:
|
||||
channels:
|
||||
telegram: 100% # 全量
|
||||
discord: 50% # 灰度 50%
|
||||
wechat: 0% # 不启用
|
||||
```
|
||||
实现：nginx/load balancer 按 channel header 权重分流
|
||||
|
||||
**策略 2：按用户特征灰度**
|
||||
```go
|
||||
// 按 user_id hash 分桶，10% 用户先跑新版本
|
||||
func inRollout(userID string, percentage int) bool {
|
||||
h := crc32.ChecksumIEEE([]byte(userID))
|
||||
return int(h%100) < percentage
|
||||
}
|
||||
```
|
||||
|
||||
**策略 3：金丝雀 + 监控**
|
||||
1. 部署新版本到 1 个 Pod（10% 流量）
|
||||
2. 观察 30 分钟：错误率、P99、审计日志量
|
||||
3. 无异常则扩大至 50%，再观察
|
||||
4. 全量切流后保留旧 Pod 5 分钟备 rollback
|
||||
|
||||
### 6.5 SLO / 告警定义
|
||||
|
||||
```yaml
|
||||
# alerts.yaml
|
||||
slo:
|
||||
availability:
|
||||
target: 99.5%
|
||||
window: 7d
|
||||
metric: cs_http_requests_total{status!~"5.."} / cs_http_requests_total
|
||||
latency_p99:
|
||||
target: 10s
|
||||
window: 5m
|
||||
metric: cs_http_request_duration_seconds{p quantile="0.99"}
|
||||
error_rate:
|
||||
target: <1%
|
||||
window: 5m
|
||||
metric: cs_http_requests_total{status=~"5.."} / cs_http_requests_total
|
||||
alerts:
|
||||
- name: HighErrorRate
|
||||
expr: rate(cs_http_requests_total{status=~"5.."}[5m]) > 0.05
|
||||
severity: critical
|
||||
- name: TicketAuditFailure
|
||||
expr: rate(cs_ticket_state_transitions_total{action="audit_fail"}[5m]) > 0
|
||||
severity: critical
|
||||
- name: LLMHighLatency
|
||||
expr: cs_llm_call_duration_seconds{p quantile="0.99"} > 10
|
||||
severity: warning
|
||||
```

## 7. 漂移检测汇总与修复优先级
|
||||
|
||||
### 7.1 已确认漂移
|
||||
|
||||
| # | 漂移描述 | 严重性 | 修复文件/方案 |
|
||||
|---|---------|-------|-------------|
|
||||
| D-1 | `session.StatusWaitingFeedback` 缺失 | P1 | `domain/session/session.go` + migration |
|
||||
| D-2 | `tenant_id` 缺失（多租户支持） | P0 | 新 migration `0002` |
|
||||
| D-3 | `cs_agent_sessions` / `cs_agent_stats` 缺失 | P1 | 新 migration `0003` |
|
||||
| D-4 | `assigned_at` 缺失（工单 SLA 计算） | P1 | 新 migration `0004` |
|
||||
| D-5 | `cs_channel_bindings` 缺失 | P1 | 新 migration `0005` |
|
||||
| D-6 | Webhook nonce 防重放未持久化 | P0 | 新 `nonce_store.go` + migration |
|
||||
| D-7 | `Resolve` 时 source_ip 未写入 audit（audit_store 仅写 NULLIF('','')） | P1 | `ticket_workflow.go` writeAudit 调用处已正确传参，但审计写入失败静默 |
|
||||
| D-8 | `IntegrationPlugin` 接口缺失 | P1 | 新 `internal/plugin/plugin.go` |
|
||||
| D-9 | `metrics/tracing` 完全缺失 | P1 | 新 `internal/platform/metrics/` 和 `tracing/` |
|
||||
| D-10 | 排队位置查询接口未定义和实现 | P1 | 新 handler + 接口定义 |
|
||||
| D-11 | `Resolve` vs `Close` 语义未文档化 | P0 | 更新 `tech/INTERFACE.md` |
|
||||
| D-12 | HLD 说 "resolved 后自动 close"，代码是独立 close | P1 | 需要产品确认 |
|
||||
|
||||
### 7.2 不需要修复的确认对齐
|
||||
|
||||
| 确认项 | 结论 |
|
||||
|-------|-----|
|
||||
| `/webhook/{channel}` 路由 | ✅ 已实现（通过 path manipulation hack） |
|
||||
| HMAC 签名校验 | ✅ 已实现 |
|
||||
| 防重放（skew 校验） | ✅ 已实现（但无 nonce 持久化） |
|
||||
| 幂等去重 | ✅ 已实现 |
|
||||
| Ticket assign/resolve audit 写入 | ✅ 已实现（`ticket_workflow.go`） |
|
||||
| 安全拒绝事件 audit | ✅ 已实现（`webhook_handler.auditRejectedRequest`） |
|
||||
| 消息处理 audit | ✅ 已实现 |
|
||||
|
||||
---
|
||||
|
||||
## 8. 需要 TechLead 决策的问题
|
||||
|
||||
1. **`resolved` 后的 close 语义**：系统自动 close 还是人工触发？
|
||||
2. **Audit 写入失败是否回滚**：ticket assign/resolve 的 audit 失败是否回滚 DB 状态变更？
|
||||
3. **TenantID 来源**：从 JWT token 提取还是从 channel context 传入？影响多租户架构。
|
||||
4. **Metrics 存储选型**：Prometheus（单体） vs VictoriaMetrics（可集群），影响 SLO 长期存储。
|
||||
5. **排队等待时间估算**：基于平均处理时间估算还是基于历史实际？
|
||||
|
||||
---
|
||||
|
||||
## 9. 实施顺序建议
|
||||
|
||||
### Phase 1（立即执行，可并行）
|
||||
1. Migration `0002-0005`（Schema 补全）
|
||||
2. Nonce Store 持久化防重放
|
||||
3. IntegrationPlugin 接口框架
|
||||
|
||||
### Phase 2
|
||||
1. Metrics + Tracing 基础设施
|
||||
2. 排队位置查询接口
|
||||
3. Session waiting_feedback 状态补齐
|
||||
|
||||
### Phase 3
|
||||
1. 灰度/回滚 Runbook 文档
|
||||
2. SLO / Alert 规则
|
||||
3. 文档与代码对齐（D-11, D-12）

## 8. 发布门禁与阶段结论
|
||||
|
||||
### 8.1 发布门禁检查表
|
||||
|
||||
所有门禁项全部通过前，不得宣告达到生产可交付标准：
|
||||
|
||||
- [ ] 独立运行模式启动成功，`/actuator/health/live` 与 `/actuator/health/ready` 返回 200
|
||||
- [ ] 集成运行模式中 `IntegrationPlugin` 已真实挂载到 gateway 主进程，而非仅存在接口定义
|
||||
- [ ] OpenAPI 文档与实际路由、错误码、鉴权要求一致
|
||||
- [ ] 渠道 Webhook 签名校验、重放保护、幂等处理验证通过
|
||||
- [ ] RBAC 与资源级隔离验证通过，跨用户/跨角色访问返回 403
|
||||
- [ ] 审计日志对会话、工单、知识库变更全量留痕，写失败会阻断高风险操作
|
||||
- [ ] Prompt Injection、越权访问、适配层限流/熔断三类高风险测试全部通过
|
||||
- [ ] 至少一条主路径、一条关键失败路径、一条集成模式链路完成真实验证
|
||||
|
||||
### 8.2 阶段门控结论
|
||||
|
||||
**当前结论：REQUEST_CHANGES**
|
||||
|
||||
**进入开发/实现前必须补齐：**
|
||||
- 将 HLD 中的威胁建模点全部映射到可执行测试用例与阻断项。
|
||||
- 为“定义 → 装配 → 调用 → 入口”四层链路补充 QA 检查说明，防止只验证接口定义。
|
||||
- 为独立运行 / 集成运行分别指定最小启动验证命令与预期结果。
|
||||
|
||||
**阻断条件：**
|
||||
- 只验证文档、未验证真实挂载入口。
|
||||
- 只覆盖 happy path，未覆盖越权/审计/签名失败/适配层失控等失败路径。
|
||||
- 无法证明客服主链路在独立与集成两种模式下都可运行。

|
||||
| 截断触发审计事件 | ✅ `TestWebhook_ContentBoundary_AuditOnTruncation` |
|
||||
|
||||
**评估**：✅ 完全覆盖，包括截断行为和审计触发。
|
||||
|
||||
### 2.2 置信度阈值边界（0.59/0.60/0.61）
|
||||
|
||||
| 测试 | 状态 |
|
||||
|------|------|
|
||||
| confidence = 0.59（< 0.60）→ handoff P2 | ✅ `TestShouldHandoff_ConfidenceBoundary` |
|
||||
| confidence = 0.60（= 0.60）→ no handoff | ✅ `TestShouldHandoff_ConfidenceBoundary` |
|
||||

|
||||
|
||||
**评估**：✅ 完全覆盖，在 `internal/service/handoff/service_test.go` 中覆盖了 turnCount=5 和 turnCount=4 的组合场景。
|
||||
|
||||
### 2.3 Rate Limit 边界（10/11 请求）
|
||||
|
||||
| 测试 | 状态 |
|
||||
|------|------|
|
||||
| 5 请求（< 10）全部通过 | ✅ `TestWebhookRateLimit_WithinLimit` |
|
||||
| 10 请求（= limit）全部通过 | ✅ `TestWebhookRateLimit_ExceedLimit` 中前 10 个 |
|
||||
| 11 请求（> 10）返回 429 | ✅ `TestWebhookRateLimit_ExceedLimit` |
|
||||

|
||||
|
||||
---
|
||||
|
||||
## 3. 测试隔离审查
|
||||
|
||||
### 3.1 外部状态依赖
|
||||
|
||||
**内存存储（memory store）**：所有 handler 和 service 测试使用 `memory.New*Store()`，每个测试函数创建独立实例，无共享状态。
|
||||
|
||||
**审查结果**：✅ 无外部状态依赖，隔离良好。
|
||||
|
||||
### 3.2 Postgres 测试隔离
|
||||
|
||||
| 问题 | 现状 |
|
||||
|------|------|
|
||||
| `migrate_test.go` 是否使用真实 DB？ | ❌ 否，仅测试目录不存在的错误路径 |
|
||||
| 是否有 `sqlmock` 配置？ | ❌ 未发现 |
|
||||
| 是否有事务回滚机制？ | ❌ 未发现 |
|
||||
| `store/postgres` 包覆盖率 | 🔴 1.6%（仅 1 个错误路径测试） |
|
||||
|
||||
**问题**：`internal/store/postgres` 的真实查询逻辑（CRUD）完全没有测试覆盖。没有使用 `sqlmock` 模拟数据库响应。
|
||||
|
||||
**建议**：为 `store/postgres` 添加 `sqlmock` 测试，验证 SQL 查询、参数绑定和错误处理。
|
||||
|
||||
### 3.3 测试并行性
|
||||
|
||||
`test/integration/` 和 handler 测试均使用 `t.Run` 子测试，但**未发现 `t.Parallel()` 调用**。在测试用例较少时这不是问题，但随着测试数量增长，并行化可以显著缩短 CI 时间。
|
||||
|
||||
---
|
||||
|
||||
## 4. 覆盖率盲区分析
|
||||
|
||||
### 4.1 严重盲区（必须修复）
|
||||
|
||||
1. **`cmd/ai-customer-service`（0%）**：main.go 入口完全没有测试，无法验证启动流程、flag 解析、环境变量加载。
|
||||
2. **`internal/http`（0%）**：HTTP 中间件、请求解析、响应序列化无测试。
|
||||
3. **`internal/store/memory`（0%）**：内存存储的并发安全（RWMutex）、容量限制、淘汰策略完全没有测试。
|
||||
4. **`internal/store/postgres`（1.6%）**：真实数据库查询（会话存储、工单存储、知识库）完全没有覆盖。
|
||||
5. **`internal/service/reply`（5.7%）**：RAG 检索逻辑、回复生成降级、回复缓存等核心逻辑覆盖严重不足。
|
||||
6. **`internal/app`（20.7%）**：应用层编排逻辑覆盖不足。
|
||||
|
||||
### 4.2 中等盲区
|
||||
|
||||
7. **`internal/platform/health`（0%）**：健康检查探针逻辑无测试。
|
||||
8. **`internal/platform/logging`（0%）**：日志结构化输出、level 过滤无测试。
|
||||
|
||||

|
||||
|
||||
## 5. 测试设计符合度
|
||||
|
||||
对照 `TEST_DESIGN.md`：
|
||||
|
||||
| 要求 | 实际 | 状态 |
|
||||
|------|------|------|
|
||||
| domain ≥ 70% | `cserrors` 100% ✅，`ticket/session` [no statements] ⚠️ | 🟡 |
|
||||
| service/handler ≥ 80% | handoff 100% ✅，intent 80.8% ✅，httpx 84.3% ✅，handlers 72.1% 🟡，dialog 48.7% 🔴，reply 5.7% 🔴 | 🟡 |
|
||||
| AC-01~AC-13 全部有测试 | 部分覆盖，未见完整对应矩阵 | 🟡 |
|
||||
| EC-01~EC-10 全部有验证 | TEC-01/02/03 有覆盖，EC-04~EC-10 未见具体测试 | 🟡 |
|
||||
| sqlmock 用于 PostgreSQL | ❌ 未配置 | 🔴 |
|
||||
|
||||
---
|
||||
|
||||
## 6. 改进建议（按优先级）
|
||||
|
||||
### P0 - 阻断性问题
|
||||
|
||||
1. **为 `cmd/` 添加启动测试**：验证 main.go 在正常配置和错误配置下的行为。
|
||||
2. **为 `internal/store/postgres` 添加 sqlmock 测试**：至少覆盖会话存储、工单创建/查询的 SQL 逻辑。
|
||||
3. **为 `internal/store/memory` 添加并发安全测试**：验证 RWMutex 保护下的并发读写。
|
||||
|
||||
### P1 - 高优先级
|
||||
|
||||
4. **为 `internal/service/reply` 添加 RAG 检索测试**：模拟检索结果为空、低分、超长文本等场景。
|
||||
5. **为 `internal/service/dialog` 补充边界测试**：当前只有 2 个测试，覆盖对话去重和工单生成，需要补充多轮对话上下文、转人工条件、敏感意图识别等场景。
|
||||
6. **配置 E2E 测试矩阵到代码**：将 `TEST_DESIGN.md` 中的 TCS-*/TEC-* 用例编号映射到实际测试函数，便于追踪覆盖率。
|
||||
|
||||
### P2 - 建议改进
|
||||
|
||||
7. 为 integration 测试添加 `t.Parallel()`。
|
||||
8. 为 `internal/http` 添加中间件测试（认证、签名校验、请求体限制）。
|
||||
9. 补充 EC-04~EC-10 的可执行测试用例。

| 测试隔离 | 7/10 | memory store 隔离好；postgres 无真实 DB 测试，无 sqlmock |
|
||||
| 覆盖率 | 4/10 | 8 个包 0%，主链路 cmd/http/store 严重缺失 |
|
