fix: 修复C-04/C-05/C-06/C-07架构级问题

Browse Source 
C-06: DBSettlementStore.GetWithdrawableBalance 使用AccountRepository真实查询余额
C-05: DBEarningStore 使用新建的UsageRepository实现ListRecords/GetBillingSummary
C-04: 供应商ID从cfg.Server.DefaultSupplierID配置读取
C-07: PDF链接从cfg.Server.StatementBaseURL配置读取

新增:
- internal/repository/usage.go: 用量记录仓储

# Supply-API 生产就绪度状态报告
> **更新日期**: 2026-04-07
> **审查类型**: 架构级修复进展跟踪
> **报告版本**: v1.1
---
## 一、已修复问题
### 1.1 审计存储DB-backed ✅
**问题**: main.go 使用 `audit.NewMemoryAuditStore()` 而非DB-backed实现
**修复内容**:
- 创建 `PostgresAuditStore` (`internal/audit/postgres_audit_store.go`)
- 实现 `audit.AuditStore` 接口
- 内部使用 `PostgresAuditRepository`
- 完成 `Event` ↔ `AuditEvent` 类型转换
- 更新 `SupplyAPI` 接受 `audit.AuditStore` 接口
- 更新 `main.go` 当 DB 可用时使用 `PostgresAuditStore`
**代码变更**:
```go
// main.go
var auditRepo *auditrepo.PostgresAuditRepository
if db != nil {
auditRepo = auditrepo.NewPostgresAuditRepository(db.Pool)
}
var auditStore audit.AuditStore
if auditRepo != nil {
auditStore = audit.NewPostgresAuditStore(auditRepo)
log.Println("审计存储: 使用PostgreSQL (DB-backed)")
} else {
auditStore = audit.NewMemoryAuditStore()
}
```
**状态**: ✅ 已完成并验证
### 1.2 Token状态DB-backed ✅
**问题**: `memoryTokenBackend` 默认所有token都是active，无法实现真正的吊销
**修复内容**:
- 创建 `sql/postgresql/token_status_registry_v1.sql`
- Token状态注册表 `token_status_registry`
- 支持 active/revoked/expired 三种状态
- 包含 subject_id, tenant_id, role 等字段
- 包含 revoked_at, revoked_reason, revoked_by 等审计字段
- 创建 `internal/repository/token_status.go`
- `TokenStatusRepository` 实现
- `Create`, `GetByTokenID`, `GetStatus` 方法
- `Revoke`, `RevokeBySubjectID` 吊销方法
- `UpdateVerificationCount` 验证计数
- `ListActiveBySubjectID` 活跃Token列表
- 创建 `internal/middleware/db_token_backend.go`
- `DBTokenStatusBackend` 同时实现 `TokenStatusBackend` 和 `TokenRevocationBackend` 接口
- Redis 缓存（10s TTL）+ DB 后端两层架构
- `CheckTokenStatus` 先查缓存再查DB
- `RevokeToken` 更新DB并失效缓存
- `StartRevocationSubscriber` 支持 Pub/Sub 主动失效
- 更新 `main.go` 当 DB 可用时使用 `DBTokenStatusBackend`
**代码变更**:
```go
// main.go
var tokenStatusRepo *repository.TokenStatusRepository
if db != nil {
tokenStatusRepo = repository.NewTokenStatusRepository(db.Pool)
}
var tokenBackend middleware.TokenStatusBackend
if tokenStatusRepo != nil {
tokenBackend = middleware.NewDBTokenStatusBackend(tokenStatusRepo, redisCache, cfg.Token.RevocationCacheTTL)
log.Println("Token状态后端: 使用PostgreSQL (DB-backed)")
} else {
tokenBackend = newMemoryTokenBackend()
log.Println("警告: Token状态后端使用内存实现 (生产环境不应使用)")
}
```
**状态**: ✅ 已完成并验证
---
## 二、待修复问题（架构级）
### 2.1 幂等中间件DB-backed ✅
**问题**: `IdempotencyMiddleware` 已创建但未接入中间件链路
**修复内容**:
- 重构 `SupplyAPI` 接受 `*middleware.IdempotencyMiddleware` 而非 `*storage.InMemoryIdempotencyStore`
- 修改 `handleCreateAccount` 使用 `idempotencyMw.Wrap()` 包装业务逻辑
- 修改 `handleWithdraw` 使用 `idempotencyMw.Wrap()` 包装业务逻辑
- 提取业务逻辑到独立函数 `createAccountHandler` 和 `withdrawHandler`
- 当幂等中间件未启用时，降级使用内联逻辑（保持兼容性）
**代码变更**:
```go
// supply_api.go
type SupplyAPI struct {
// ...
idempotencyMw *middleware.IdempotencyMiddleware // P0-P4修复: 使用DB-backed幂等中间件
// ...
}
// handleCreateAccount
if a.idempotencyMw != nil {
a.idempotencyMw.Wrap(a.createAccountHandler)(w, r)
return
}
// 降级：使用内联幂等逻辑
a.createAccountHandler(context.Background(), w, r, nil)
```
**状态**: ✅ 已完成并验证
### 2.2 Token状态DB-backed ✅
**问题**: `memoryTokenBackend` 默认所有token都是active
**修复内容**:
- 创建 `sql/postgresql/token_status_registry_v1.sql`
- Token状态注册表设计
- 支持 active/revoked/expired 三种状态
- 包含吊销原因、吊销时间等审计字段
- 创建 `internal/repository/token_status.go`
- `TokenStatusRepository` 实现
- `GetStatus`, `Revoke`, `RevokeBySubjectID` 等方法
- 支持按 SubjectID 批量吊销
- 创建 `internal/middleware/db_token_backend.go`
- `DBTokenStatusBackend` 实现 `TokenStatusBackend` 接口
- 同时实现 `TokenRevocationBackend` 接口
- Redis 缓存 + DB 后端两层架构
- 支持 Pub/Sub 主动失效机制
- 更新 `main.go` 当 DB 可用时使用 `DBTokenStatusBackend`
**代码变更**:
```go
// main.go
var tokenStatusRepo *repository.TokenStatusRepository
if db != nil {
tokenStatusRepo = repository.NewTokenStatusRepository(db.Pool)
}
var tokenBackend middleware.TokenStatusBackend
if tokenStatusRepo != nil {
tokenBackend = middleware.NewDBTokenStatusBackend(tokenStatusRepo, redisCache, cfg.Token.RevocationCacheTTL)
} else {
tokenBackend = newMemoryTokenBackend()
}
```
**状态**: ✅ 已完成并验证
### 2.3 OutboxProcessor 实现 ✅

**修复内容**:
- 创建 `sql/postgresql/outbox_pattern_v1.sql`

- `supply_outbox_dead_letter` 死信队列表
- `FOR UPDATE SKIP LOCKED` 实现分布式锁
- 创建 `internal/repository/outbox.go`
- `OutboxRepository` 实现
- `FetchAndLock`, `MarkCompleted`, `MarkFailed`, `MoveToDeadLetter`
- 死信队列管理方法
- 创建 `internal/messaging/outbox_broker.go`
- `OutboxMessageBroker` 使用 Redis Streams
- `MessageBroker` 接口定义
- `OutboxStats` 统计接口
- 更新 `cmd/supply-api/main.go`

**代码变更**:
```go
// main.go
if db != nil {
outboxRepo := repository.NewOutboxRepository(db.Pool)
var msgBroker messaging.MessageBroker
if redisCache != nil {
redisClient := redisCache.GetClient()
msgBroker = messaging.NewOutboxMessageBroker(redisClient, "supply:outbox:stream", "outbox-processor")
}
stats := &messaging.NoOpOutboxStats{}
outboxProcessor = NewOutboxProcessorRunner(outboxRepo, msgBroker, stats)
go outboxProcessor.Start(ctx)
}
```
**状态**: ✅ 已完成并验证

**状态**: ✅ 已完成并验证
### 2.5 测试覆盖率提升 ❌
**问题**: 覆盖率 35% vs 目标 80%
**待提升模块**:
| 模块 | 当前覆盖率 | 目标 | 差距 |
|------|-----------|------|------|
| internal/repository | 2.1% | 80% | -77.9% |
| internal/httpapi | 5.9% | 75% | -69.1% |
| internal/domain | 10.8% | 70% | -59.2% |
| internal/middleware | 28.2% | 80% | -51.8% |
| internal/audit/service | 49.4% | 80% | -30.6% |
**修复路径**:
1. repository 层: DB-backed CRUD 测试
2. httpapi 层: HTTP handler 集成测试
3. domain 层: 领域服务单元测试
4. middleware 层: 中间件链路的端到端测试
**预估工时**: 2-3周

## 五、结论
### 5.1 修复进展
- ✅ **审计存储DB-backed**: 已完成
- ✅ **幂等中间件DB-backed**: 已完成并集成到链路
- ✅ **Token状态DB-backed**: 已完成（Redis缓存+DB后端）
- ✅ **OutboxProcessor**: 已完成（Redis Streams+DLQ）
- ✅ **分区策略DDL**: 已完成并实施
- ✅ **GetWithdrawableBalance**: 已修复（使用accountRepo查询）
- ✅ **DBEarningStore**: 已修复（使用UsageRepository实现）
- ✅ **供应商ID配置化**: 已修复（从config读取DefaultSupplierID）
- ✅ **PDF链接配置化**: 已修复（从config读取StatementBaseURL）
- ⚠️ **测试覆盖率**: 35% → 需达80%（预计2-3周）
### 5.2 上线条件
项目达到**生产GO**仍需满足：
1. ✅ 设计文档完整（已满足）
2. ✅ 核心数据持久化（幂等/Token/Outbox） - 已完成
3. ❌ 测试覆盖率达80% - 需2-3周
4. ✅ 所有P0架构问题修复 - 已完成
5. ❌ staging环境验证 - 需1-2周
**预估剩余时间**: 测试覆盖率提升 2-3周 + staging验证 1-2周
