PowerX CRUD Repository
步骤
- 打开
本文件内嵌规则。
- 按规则执行实现/校对。
- 完成后按核对清单验收。
核对点
- 与 PowerX 当前代码结构、路径与命名一致。
- 仅在传输层/契约层做职责内改动,不跨层越界。

统一 Repository(持久化)层的接口与实现规范:只负责数据访问与映射,
不承载业务逻辑;严格多租户隔离、软删、分页筛选与一致的错误/返回语义。
CoreX 模块仓储统一采用 BaseRepository 泛型封装,便于事务注入与测试。

scope:
codebase:
repo_globs:
- "internal/repository/**/**_repo.go"
- "pkg/corex/db/persistence/repository/**/**_repo.go"
model_globs:
- "pkg/corex/db/persistence/model/**/**.go"
principles:
- 目录规范:CoreX 仓库实现放置于 `pkg/corex/db/persistence/repository/<domain>/`,目录名使用 snake_case,对应的模型位于同层级 `model/`。
- 职责单一:Repository 只做数据访问(SQL/GORM),禁止业务分支与权限判断。
- 多租户强约束:所有查询均带 TenantID 条件;默认忽略软删(GORM 默认生效)。
- 事务注入:方法接受 *gorm.DB(可为 tx),由 Service 层控制 tx 生命周期。
- 上下文贯穿:方法首参为 context.Context,用于 tracing/超时/审计钩子。
- 错误语义:不存在返回 gorm.ErrRecordNotFound(由 Service 翻译成 404);唯一冲突返回 ErrConflict(由 Service 翻译 409)。
- 可测试性:提供接口与实现;实现命名 `XxxRepoImpl`,禁止全局单例。
- 性能:列表查询必须显式选择字段/建立索引,禁止 N+1(注意 Preload 选择性)。

checklist:
- "[ ] 每个仓库文件包含接口 + 实现 + New 构造函数"
- "[ ] 方法签名统一为 (ctx context.Context, db *gorm.DB, ...)"
- "[ ] 所有查询带 TenantID 条件(Where/Scopes/TenantScope)"
- "[ ] 列表查询有分页(Limit/Offset 或 Cursor)"
- "[ ] 不做业务鉴权/分支;错误语义由 Service 统一翻译"
- "[ ] 使用软删;如需硬删必须在 Service 授权并清晰标注"
- "[ ] 可被 DI 装配(由 Deps 提供 *gorm.DB 注入)"
