 构建/发布不再改写版本文件，而是读取仓库已提交版本，并在发布前做两件事：
 
 1. 校验五个版本来源一致，不一致会中止，防止漂移。
-2. 通过 `assertVersionNotBelowOss` 读取 OSS `latest.json`：若仓库版本**低于**线上版本会中止，
+2. 校验版本相对 `HEAD` 已提交（`assertVersionCommitted`）：若版本文件存在未提交改动会中止，
+   确保本地发布与 Jenkins 检出的是同一个版本。
+3. 通过 `assertVersionNotBelowOss` 读取 OSS `latest.json`：若仓库版本**低于**线上版本会中止，
    并提示先运行 `bump-version`，避免回退线上版本；OSS 读取失败或清单格式错误同样会中止。
    仓库版本等于或高于线上版本才放行。
