+  ✅ Router: 94.8%
+```
+
+---
+
+## 四、代码安全规范（新增）
+
+### 4.1 日志安全规范
+
+```go
+// ❌ 禁止：日志中打印敏感信息
+log.Printf("connected to database: %s", cfg.DSN())
+
+// ✅ 正确：使用SafeDSN()脱敏
+log.Printf("connected to database: %s", cfg.SafeDSN())
+
+// ❌ 禁止：错误信息中泄露密码
+return nil, fmt.Errorf("failed to parse config: %w", err)
+
+// ✅ 正确：清理错误信息中的密码
+return nil, fmt.Errorf("failed to parse %s: %v", cfg.SafeDSN(), sanitizeErrorPassword(err, password))
+```
+
+### 4.2 正则表达式安全规范
+
+```go
+// ❌ 禁止：MustCompile可能panic
+pattern := regexp.MustCompile(userInput)
+
+// ✅ 正确：使用Compile并处理错误
+pattern, err := regexp.Compile(userInput)
+if err != nil {
+    // fallback或返回错误
+    pattern = regexp.MustCompile("a^") // 永远不匹配
+}
+```
+
+### 4.3 Context值类型规范
+
+```go
+// ❌ 禁止：值类型拷贝导致悬空指针
+ctx.WithValue(ctx, key, value)        // value是值类型
+if v, ok := ctx.Value(key).(Type); ok {
+    return &v  // BUG: 返回指向栈帧的指针
+}
+
+// ✅ 正确：使用指针类型
+ctx.WithValue(ctx, key, &value)       // value是指针
+if v, ok := ctx.Value(key).(*Type); ok {
+    return v  // 正确
+}
+```
+
+### 4.4 并发安全规范
+
+```go
+// ✅ 使用RWMutex保护map
+type SafeMap struct {
+    mu    sync.RWMutex
+    items map[string]*Item
+}
+
+// ✅ 原子操作用于计数器
+index := atomic.AddUint64(&counter, 1) - 1
+
+// ✅ 互斥锁保护临界区
+s.idempotencyMu.Lock()
+defer s.idempotencyMu.Unlock()
+```
+

+
+## 五、问题优先级定义（规范固化）

+| **P0** | 阻塞性问题，导致系统不可用或数据损坏 | 立即修复 | 内存泄漏、竞态条件、安全漏洞 |
+| **P1** | 重要问题，影响核心功能 | 24小时内修复 | 性能下降、边界条件未处理 |
+| **P2** | 轻微问题，不影响核心功能 | 本周修复 | 代码规范、日志完善 |
+| **P3** | 优化项 | 计划修复 | 代码重构、文档完善 |
+
+### 5.2 HIGH/MED安全问题定义
+
+| 级别 | CVSS范围 | 定义 | 示例 |
+|------|----------|------|------|
+| HIGH | 7.0-10 | 高危安全漏洞 | JWT算法验证不严格、SQL注入风险 |
+| MED | 4.0-6.9 | 中危安全漏洞 | 错误信息泄露、日志注入风险 |
+| LOW | 0.1-3.9 | 低危安全问题 | 弱加密算法配置 |
+
+### 5.3 问题修复验证流程
+
+```
+1. 修复代码
+2. 添加/更新测试用例
+3. 运行测试验证
+4. 代码审查
+5. 提交并推送
+6. 更新问题追踪
+```
+
+---
+
+## 六、成功经验总结
+
+### 6.1 证据链驱动
+
+- **所有结论必须附带证据**（报告、日志、截图）
+- 脚本返回码+报告双重校验
+- Checkpoint机制确保逐步验证
+- 测试覆盖率量化验证
+
+### 6.2 TDD开发流程
+
+```
+RED:    编写失败的测试用例
+GREEN:  编写最小代码使测试通过
+REFACTOR: 重构代码，验证测试仍通过
+```
+
+**验证结果**：
+- IAM模块：111个测试，99.0%覆盖率
+- 审计日志模块：40+个测试，75%+覆盖率
+- 路由策略模块：33+个测试，94.8%覆盖率
+
+### 6.3 分层验证策略
+
+```
+local/mock → staging → production
+```
+
+- local/mock用于开发验证
+- staging用于真实环境验证
+- 两者结果不可混用
+
+### 6.4 并行任务拆分
+
+- P0阻塞时识别P1/P2可并行任务
+- 多Agent并行执行提升效率
+- 减少等待浪费
+
+### 6.5 深度审查驱动改进
+
+- **高标准审查**发现47个问题，其中8个P0
+- 通过系统性修复，所有P0/P1/P2问题已解决
+- 审查报告作为知识沉淀，指导后续开发
+
+---
+
+## 七、规范更新
+
+### 7.1 新增规范
+
+| 规范 | 说明 |
+|------|------|
+| 日志安全规范 | SafeDSN、错误信息脱敏 |
+| 正则安全规范 | MustCompile替代方案 |
+| Context类型规范 | 指针类型存储 |
+| 并发安全规范 | RWMutex、原子操作 |
+
+### 7.2 测试覆盖率基线
+
+| 模块类型 | 最低覆盖率 | 目标覆盖率 |
+|----------|------------|------------|
+| 核心业务模块 | 70% | 85%+ |
+| 安全关键模块 | 80% | 95%+ |
+| 基础设施模块 | 30% | 50%+ |
+
+### 7.3 代码审查清单
+
+```
+□ P0问题：无阻塞性Bug
+□ 安全检查：无HIGH/MED漏洞
+□ 测试覆盖：核心模块≥85%
+□ 并发安全：无竞态条件
+□ 日志安全：无敏感信息泄露
+□ 错误处理：所有错误被捕获或返回
+```
+
+---
+
+## 八、后续行动项
+
+| 优先级 | 任务 | 状态 |
+|--------|------|------|
+| P0 | staging环境验证 | IN PROGRESS |
+| P1 | 补充剩余模块集成测试 | TODO |
+| P2 | 合规能力包CI脚本开发 | TODO |
+| P2 | SSO方案实施（Casdoor） | TODO |
+
+---
+
+## 九、附录
+
+### 9.1 关键文档
+
+| 文档 | 路径 |
+|------|------|
+| **深度质量审查报告** | reports/review/deep_quality_review_2026-04-03.md |
+| PRD | docs/llm_gateway_prd_v1_2026-03-25.md |
