feat: 全12服务DDD重构 + 公告定向推送系统 (移植自rwadurian)
## 一、DDD + Clean Architecture 重构 (全12服务)
对全部12个微服务(9 NestJS + 3 Go)实施严格的DDD分层:
### NestJS 服务 (9个):
- auth-service: JWT策略已在domain层
- user-service: 新增 5 个 repository interface + implementation,
5 个 value objects (Email/Phone/KycLevel/Money), 3 组 domain events
- issuer-service: 新增 5 个 repository interface + implementation,
3 个 value objects, 2 组 domain events, external AI client port
- clearing-service: 新增 5 个 repository interface + implementation,
2 个 value objects, domain events
- compliance-service: 新增 7 个 repository interface + implementation,
2 个 value objects, domain events, audit logger service
- ai-service: 新增 conversation repository + TypeORM entity,
AI agent client port 移至 domain/ports/
- notification-service: 新增 notification repository interface +
implementation, channel providers, value objects
- telemetry-service: 新增 3 个 repository interface + implementation
- admin-service: 新增 app-version repository interface + implementation
### Go 服务 (3个):
- trading-service: 重构为 domain/application/infrastructure 分层,
新增 repository interface + postgres 实现, matching engine 移入
application/service, 新增 value objects (Price/Quantity/OrderSide/OrderType),
Kafka event publisher
- translate-service: 新增 repository interface + postgres 实现,
value objects (Address/ChainType)
- chain-indexer: 新增 repository interface + postgres 实现,
value objects (BlockHeight/TxHash), Kafka event publisher
### 关键模式:
- NestJS: Symbol token DI (provide: Symbol → useClass: Impl)
- Go: compile-time interface check (var _ Interface = (*Impl)(nil))
- TypeORM entity 保留 domain methods (pragmatic DDD)
- Repository interface 在 domain/, 实现在 infrastructure/persistence/
## 二、公告定向推送系统 (ported from rwadurian)
在 notification-service 中新增 Announcement 公告体系,
支持管理端向全体/标签/指定用户推送消息:
### 数据库:
- 038_create_announcements.sql: 5张新表
- announcements (公告主表)
- announcement_tag_targets (标签定向)
- announcement_user_targets (用户定向)
- announcement_reads (已读记录)
- user_tags (用户标签)
### 三种定向模式:
- ALL: 推送给全体用户
- BY_TAG: 按标签筛选用户 (用户标签与公告标签有交集)
- SPECIFIC: 指定用户ID列表
### 新增文件 (15个):
- 5 个 TypeORM entity (Announcement + Read + TagTarget + UserTarget + UserTag)
- 2 个 repository interface (IAnnouncementRepository 11方法, IUserTagRepository 6方法)
- 2 个 repository 实现 (TypeORM QueryBuilder, targeting filter SQL)
- 2 个 application service (AnnouncementService, UserTagService)
- 2 个 DTO 文件 (announcement.dto.ts, user-tag.dto.ts)
- 1 个 controller 文件 (含3个controller: AdminAnnouncement/AdminUserTag/UserAnnouncement)
- 1 个 migration SQL
### API 端点:
管理端:
POST /admin/announcements 创建公告(含定向配置)
GET /admin/announcements 公告列表
GET /admin/announcements/:id 公告详情
PUT /admin/announcements/:id 更新公告
DELETE /admin/announcements/:id 删除公告
GET /admin/user-tags 所有标签(含用户数)
POST /admin/user-tags/:userId 添加用户标签
DELETE /admin/user-tags/:userId 移除用户标签
PUT /admin/user-tags/:userId/sync 同步用户标签
用户端:
GET /announcements 用户公告(按定向过滤+已读状态)
GET /announcements/unread-count 未读数
PUT /announcements/:id/read 标记已读
PUT /announcements/read-all 全部已读
### 设计决策:
- Announcement 与现有 Notification 并存 (双轨):
Notification = 事件驱动1:1通知, Announcement = 管理端广播/定向
- rwadurian accountSequences → gcx userIds (UUID)
- rwadurian Prisma → gcx TypeORM
