`armor/` 是它的 Rust 改写版，这一份留着当参考：ADC 阈值的 2000 就是从它标定出来的 （`.env.example` 里那句 "same as the reference firmware" 指的就是它），而且它的 README 记着实测设备与 MAC，换硬件时是有用的现场记录。 只收了 20 个源文件。它自带的 `.gitignore` 已经排掉 `build/`（211 MB 的 ESP-IDF 构建产物） 与生成的 `sdkconfig`，所以仓库里不会多出这些东西。 两处顺带处理： - `reference/armor/.git` 是一个**空的**仓库壳（`git init` 过，零提交、零 remote、零 ref）， 而外层 git 正因为它的存在而拒绝索引 `reference/` 下的任何文件 （`error: 'reference/armor/' does not have a commit checked out`）。它被挪到 `desktop/.dev/backup/reference-armor-git`（可逆，且该目录已被忽略），不是删除。 - 它的 README 指着 `../armor-platformio-backup/`，那份备份并不存在。改成明说"没有进仓库"， 免得以后有人照着找一个不存在的目录。 另外把 `/docs/` 加进 .gitignore：那是工作区里另起的一个 Astro 文档站，与本仓库无关。
