Repo homepage sidebar shows stale contributor not present in Contributors API or /graphs/contributors

Bug

Body

I'm seeing a discrepancy on three of my repositories where the homepage sidebar "Contributors" widget shows an extra contributor that doesn't exist anywhere else in the actual data:

• https://github.com/erhnysr/basedrop
• https://github.com/erhnysr/coliseum
• https://github.com/erhnysr/tipping-base

What I've verified:

1. The official REST API (GET /repos/{owner}/{repo}/contributors) returns only me as a contributor for all three repos.
2. The /graphs/contributors page (live-computed) also correctly shows only me.
3. git log --all on the local clone of each repo shows zero references to the extra contributor in author, committer, or commit message fields.
4. For one repo (basedrop), I rewrote history with git filter-branch to remove an old co-authored-by trailer and force-pushed clean history — the sidebar still shows the stale entry days later.

This suggests the repo homepage sidebar widget is using a separate cache/render path that isn't syncing with the actual Contributors API or graphs data, and isn't invalidating even after a force-push.

Has anyone else run into this? Is there a known way to force a refresh of this specific widget, short of deleting and recreating the repo?

(I did open a support ticket — #4533166 — but was told this level of support requires a paid plan. Posting here in case anyone in the community has hit the same thing or a maintainer can take a look.)

No that's happens when you co-author a commit using an AI coding assistant (like it would do that itself) if you're referring to the Claude ones. It's not a bug and it's completely normal. Tho idk how to get rid of it. I think try clearing the git history by switches branches and replacing that one with the main one would fix it. And if I answer your questions por favor pick this comment as the answer since I need the badge 🙏🙏🙏.

The same bug affects my repository: https://github.com/yabtesfu/gan-lab-tensorflow.The official contributors API returns only @yabtesfu with 172 contributions: https://api.github.com/repos/yabtesfu/gan-lab-tensorflow/contributors. The contributor statistics endpoint also returns only @yabtesfu: https://api.github.com/repos/yabtesfu/gan-lab-tensorflow/stats/contributors. However, the repository homepage Contributors widget still incorrectly shows @claude. Current main is: 343a80fb606e0e9ed31f91f57eabde52fd2fdf92

No reachable branch, tag, author, committer, or co-author trailer contains
Claude. Please invalidate/rebuild the stale homepage contributors widget.
