Fetching the history for computing the branch diff can fail with "fatal: shallow file has changed since we read it", a git 2.54 bug which is hit especially often for old pull requests, which have a lot of history to fetch. Retry the fetch up to 3 times, and annotate the run with a warning on every retry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

With manual re-runs, it sometimes fails after even 7 retries. Shall we try 10 here? |

Downgrading Git sounds like a more reliable solution: #155495. |

Agreed. I also think that #155495 would be preferred. |

fatal: shallow file has changed since we read it, a git 2.54 bug (fixed in git 2.55, which is not yet in the runner images) which is hit especially often for old pull requests, which have a lot of history to fetch.Retry the fetch up to 5 times, and annotate the run with a warning on every retry.
