原理图/PCB 已在 EasyEDA 里做到 12 页跨页 0 漏接，固件刚完成骨架包 A1。 这次是把已有的一切一次性纳入版本控制，没有改动任何设计内容。 纳入： - 设计与需求文档、PROGRESS.md、小米8 参考原理图 PDF 与追脚脚本 - .claude/ 下的 EasyEDA 桥接工具链与几何/网表缓存（eda-parts.json、 pcb-parts.json、pcb-pads.json、p2-ch1.json 等，是重画各页的唯一事实来源） - 117 张验证截图（本项目所有方向问题都是靠人眼看截图发现的，属于证据不是垃圾） - firmware/ 的 A1 骨架与 site/ 文档站源码 .gitignore 排除：构建产物（firmware/build、host/build、sdkconfig）、 site/node_modules、__pycache__、桥接日志 _bridge.log、脚本自标的 *.stale。 .gitattributes 默认 `* -text`：现有 .py/.json 大多是 CRLF，原样存， 不让 git 重写行尾。唯一例外是 *.sh 强制 LF —— 带 \r 的 shell 脚本 bash 跑不了。 Co-Authored-By: Claude Opus 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01QYuExfgyYa6DzRRcUso8M8

u"""下板 PCB1 的**环境约束图**：把载板 PCB2 底面的东西折算到下板坐标系。
|
||
|
||
下板 160×125 居中在载板 220×135 下方 ⇒ **下板坐标 = 载板坐标 − (30, 5)**
|
||
（事实来源 `pcb2-header-pads.json` 的 frame 字段 / 设计文档 §25.1）。
|
||
两板净空 **13 mm**（§22.3f：公头塑高 2.5 + 母座塑高 10.5）。
|
||
|
||
产出 `pcb1-env.json`：
|
||
|
||
| 字段 | 含义 |
|
||
|---|---|
|
||
| `anchors` | J24 / J25 的 40 个焊盘在下板坐标下的目标位置（**对位的唯一依据**，别按引脚号推）|
|
||
| `zones` | 一堆矩形，每个带 `hmax` = 下板在这块地方允许的最大元件高度 = 13 − h载板 − 1 |
|
||
| `lanes` | 排线在载板背面占的车道（下板坐标）。排线要平贴着走，这里 `hmax` 取 11.0 |
|
||
| `slots` | 载板的 10 条穿线槽投影（下板边缘 y<1.3 / y>123.9 两条带）|
