任务规划目录从 5 个文件收敛到 3 个：只留导航（README）、待办（登记簿）、 暂缓专项（暂缓-RS485）。 删除的两个文件都不再有现行读者： - UI补齐.md 执行清单 2026-10-28 清空、上板判据 2026-11-06 台架轮已复核； 叶数口径迁 docs/UI设计/菜单页面设计.md §3.9，三条内容页硬规矩迁 docs/UI设计/内容页架构.md §7.1，两条未闭环待办迁登记簿 §7/§8。 - 数据可信.md 不是完成记录，而是被约 130 处代码头注释引用的设计约束， 因此按内容分三处落位后删除，不整篇丢弃。 数据可信内容的新归属（旧节号 → 新家）： - §2/§4 设计口径 → docs/算法/采集与算法层设计说明.md 新增 §13（13 小节）， §7 前置决策表 → §13.12 已定案的前置决策。 - §3 台阶与波次退出判据 → docs/硬件平台/ADC通道映射说明.md 新增 §9。 - §5 任务卡 → docs/任务规划/登记簿.md §7（拆成变比确认 / 两点标定两行）。 引用改写 34 文件 77 处路径引用 + 14 文件 24 处昵称引用 + 双重节号 35 处， 覆盖代码头注释、测试、生成器与文档；归档区历史路径改纯文本提及。 四个 SVG 生成器文案同步并重跑，产物随脚本同批提交。 同批处理两件事： - 9 个 UTF-16 LE 证据文件转 UTF-8。end-of-file-fixer 按字节判末尾换行， UTF-16 的换行是 0A 00、末字节 00，钩子会追加裸 0x0a 使文件变奇数长度， 8 个已实际损坏。转码后逐文件比对 HEAD 原文验证正文零丢失。 - 修回 App/cfg/cfg_file.c 被剥掉的 UTF-8 BOM（补 3 字节，未整文件重写）。 验证：/keil-build 0 错误 0 警告（Code=255160）；check_doc_links --all --sections-strict 221 篇全通过、无法判定 0；pre-commit 全量全 Passed。

"""生成 docs/images/交流定数取中位数.svg —— 交流轮为什么必须「连取 10 行心跳、取中位数」：
|
||
左半讲机理（全周窗逐拍滑动 → 单行带拍频跳动），右半讲操作（10 行里任何单行都可能撞
|
||
波峰波谷、毛刺行拖偏算术平均，中位数对两头都钝感）。
|
||
|
||
为什么不用 Mermaid：本图是两幅带刻度的数值示意图（正弦 + 窗框、散点 + 三条水平基准线），
|
||
坐标与数值就是语义本身；Mermaid 只能画盒子和箭头，画不出「中位数线贴着密集簇、
|
||
平均线被毛刺拽走」这个高度差对比。
|
||
|
||
用法（仓库根目录，任意 python3）：
|
||
python tools/arch_diagram/gen_ac_median_svg.py
|
||
输出：
|
||
docs/images/交流定数取中位数.svg
|
||
改内容：`vals` / 文案变了才重跑；调坐标编辑下方常量。数值一律硬编码，保证逐字节幂等。
