-## Registry Coverage Check Script
+## Registry Coverage Check
 
-Use the checker script to ensure this registry and frontend code mapping stay aligned:
+当前仓库未内置自动校验脚本，维护流程按以下约束执行：
 
-```bash
-python3 scripts/check_error_code_registry.py
-```
-
-Optional arguments:
-
-- `--doc`: custom registry markdown path
-- `--mapper`: custom frontend mapper path (default: `apps/lib/core/network/error_code_mapper.dart`)
-
-Output always includes three result groups:
-
-- doc has code but frontend has no mapping
-- frontend maps code but doc has no such code
-- duplicate codes
-
-Exit code policy:
-
-- `0`: no inconsistency found
-- non-`0`: at least one inconsistency found or input path invalid
+- 更新本文件错误码时，同步检查前端映射文件：`apps/lib/data/network/error_code_mapper.dart`
+- 任何新增/变更/废弃错误码必须在同一 PR 中完成「协议文档 + 前端映射 + 后端返回码」三方对齐
+- 若后续补充自动校验脚本，需在本节追加命令与输出约定
