 ## 服务路由（按关键词定位）
 
-本表只保留定位入口；命中业务后必须用 `rg -n -F '关键词' docs/backend-business-index.md` 读取对应行/段的详细约束，再沿代码引用追踪；不默认全文加载详细索引。已知目标文件时直接定位，并定向核对该业务约束。

+
+### 后端任务最小读取集
+
+- 单服务 Controller/Service/Mapper 任务：本文件、目标服务 `AGENTS.md`、目标类及其直接调用点。
+- 跨服务 API/事件任务：在上述基础上增加直接调用方、被调用方和对应 Gateway/OpenAPI；不因业务关键词自动加载整个业务专题。
+- 只有状态、权限、数据库或验收边界无法从上述入口确定时，才读取 `docs/业务快速索引.md`、专题 README 或完整契约。
+- 后端指引累计超过约 250 行时优先用 `rg` 读取命中段；聚合构建或架构任务才全文读取 `README.md`、`pom.xml` 和目录结构文档。
