post(upstream-rewrite): the wipe is verifiable in git — master is one 2026-06-22 commit ('deleted'), no common ancestor with main

Re-checked against the actual repo rather than the API summary: the old branch
survives as a single commit whose README is the word 'deleted', and it shares no
common ancestor with main's 233 commits. Sharper and fully verifiable, EN+ZH.

 And the code behind those 233 commits is not my app's codebase continued. It
 is a different application that happens to keep the name:

-2021 年那段历史没了。`created_at` 还显示 2021-08-13，只是因为 GitHub 在仓库被重新填充后保留了这个字段，但 git 历史是从 2026-09-16 一条空仓库提交开始的。被删除的痕迹还留在旧分支上：去取 `master` 的 README，全文只有两个字——`deleted`。
+2021 年那段历史还在，但已经断开了。`main` 上是 233 个提交，最早一条的日期是 2026-09-16；旧分支仍然存在，但只剩**一个提交，日期 2026-06-22**，提交信息就是 `commit`，而它的 README 全文只有一个词——`deleted`。两个分支**没有共同祖先**——这就是「先清空、再重来」在 git 里的样子。
 
 而这 233 个提交里的代码，不是我原来那个代码库的延续。它是另一个应用，只是恰好沿用了同一个名字：
