 - **范围 = 项目代码**：第三方（`Lib/`、`Middlewares/`、CMSIS、HAL、`lftpd`、`dhara`、`MDK-ARM`）排除；`cppcheck`/`coding-standard` 另排除 `test/`，规范检查再排除 CubeMX 生成的 `Src/`/`Inc/`。**`simulator/` 已纳入全部钩子**（2026-10-11）——生成物只靠 `.gitignore` 挡，**不在 `exclude` 里写目录名**（教训见 `docs/代码规范/pre-commit使用说明.md` §5.5）
 - ⚠ **pre-commit 4.x 已移除 `always: true`**（实测对 `local` 钩子只告警 `Unexpected key(s)` 并跳过）→ 想"总是跑"的钩子**必须让 `files:` 覆盖到所有会触发它的文件**，没有兜底开关
 - **改写型钩子（`trailing-whitespace` + `end-of-file-fixer`）豁免 CubeMX/Keil 生成文件**（配置里 YAML 锚点 `&cubemx-generated`）；⚠ **只读检查不受影响**：`cppcheck` / 乱码 / `cubemx-survival` / `task-table` / `mem-numbers` 仍覆盖 `Src/`、`Inc/`
