 > **为什么内嵌时区库**：Windows 没有 `/usr/share/zoneinfo`，为了 `timezone = Asia/Shanghai` 在任何机器上都可用，引入了 `time/tzdata`（约 0.5 MB）。
 
+> 改了依赖之后，请在 Windows 上额外跑一次 `GOOS=linux go build ./...` 再提交 `go.sum`：
+> 有些依赖（例如 `modernc.org/libc` 的 Linux 专用文件）只在 Linux 构建路径下被编译，
+> 只在本机 Windows 构建会漏掉它们的 `go.sum` 条目，导致 CI 报 `missing go.sum entry`。
