"""两遍构建：表盘源码 + 资源 -> dist/S5ePAnim.face / dist/S5ePAnimRestore.face
|
|||
|
|
|
|||
|
|
main.lua <- **源码**，含 __UIIMG__ / __PAY__ / __RB__ / __ROLE__ 占位符
|
|||
|
|
.work/overlay/<NAME> <- 中间产物（回填后的 Lua 落在这里）
|
|||
|
|
.work/build/<NAME> <- 编译工作区（Compiler.exe 的输入）
|
|||
|
|
dist/<NAME>.face <- 交付物
|
|||
|
|
|
|||
|
|
为什么两遍
|
|||
|
|
----------
|
|||
|
|
.face 里各资源的偏移取决于打包顺序；我们靠在 .face 里**搜字节**来定位它们。
|
|||
|
|
Lua 源码排在所有资源之后，所以回填（Lua 变长）不会移动前面的资源 —— 脚本最后逐条校验 0 漂移。
|
|||
|
|
|
|||
|
|
为什么最终产物要"再裸编一次"
|
|||
|
|
----------------------------
|
|||
|
|
两遍构建走的是 vendor 的 scripts/build_face.ps1，它在编译后调 set_face_id.ps1，
|
|||
|
|
把**头里第 5 字节写成 id 长度 10**，而固件自带表盘的 b5 是 0。
|
|||
|
|
所以交付物改从裸 `Compiler.exe -b` 的输出取（b5=0），只覆盖 40..49 = id。
|
|||
|
|
断言：裸产物与 toolchain 产物必须"只差 b5 + id 这 8 个字节"，否则直接拒绝交付。
|
|||
|
|
|
|||
|
|
两份盘共用同一个 watchface id（462150102）：装一份就顶掉另一份，设备上只占一份空间。
