+`windows-arm64` is the one row documented but **not in the current release**: the CI ARM64 runner is
+missing the Windows SDK's ARM64 import libraries — the cause is located and the fix is in progress.
+The row stays because the architecture is still supported and the slot still builds (unpublished) in
+the matrix; what decides whether a slot reaches a Release is `PUBLISH_SLOTS` in
+`.github/workflows/release.yml`, which today names `windows-x64` only — so `windows-x64` is the
+only downloadable Windows asset.

 Each UNIX archive contains the executable plus `LICENSE`, `NOTICE` and `README.md`, in one top-level
 directory. Windows ships a bare `.exe` (a single file cannot carry the texts), so those three
 documents are attached to the release next to it — downloading the Windows binary does not strip the

+`windows-arm64` 是表里唯一「写了但**本次未发布**」的一行：CI 的 ARM64 runner 上缺 Windows SDK 的
+ARM64 导入库——原因已定位，正在修。这一行不删，是因为架构仍然要支持、槽位也仍在矩阵里构建（只是不进
+Release）；决定一个槽位能否进 Release 的是 `.github/workflows/release.yml` 里的 `PUBLISH_SLOTS`，
+它现在只写了 `windows-x64`——所以 `windows-x64` 是当前唯一可下载的 Windows 资产。

 UNIX 归档里是二进制加 `LICENSE`、`NOTICE`、`README.md`，都在一个顶层目录下。Windows 发的是裸 `.exe`
 （一个文件装不下这三份文本），所以这三份作为并列资产挂在 Release 上——下 Windows 二进制不会把许可条款
 弄丢。下载链接里不带实现细节字样，归档里的二进制名永远是 `unlucky-launcher`。
