 - 使用模块路径 `senlinai-agent/backend`。
 - 业务逻辑包统一放在 `backend/internal/logic` 下，例如 `ai`、`auth`、`files`、`inbox`、`notes`、`projects`、`search`、`tasks`。
 - Gorm 模型和数据库连接入口统一放在 `backend/internal/models`，不要恢复独立的 `domain` 或 `db` 包。
-- 模型结构体使用 `SenlinAgent` 前缀，数据库表名使用 `senlin_agent_` 前缀。
+- 模型结构体使用 `Sa` 前缀，数据库表名使用 `sa_` 前缀。
 - 所有服务端本地文件路径构造必须集中在文件服务中。
 - 不允许 HTTP handler 直接构造存储路径。
 - 项目标签必须限定在项目内；MVP 阶段不要引入全局标签体系。
