Repository homepage shows a stale contributor

Bug

Body

Repository:
https://github.com/Jwz-git/my-knowledge-base

The repository homepage has incorrectly displayed the user "claude" as a contributor for more than one month.

However:

• All 29 commits on the current main branch belong to Jwz-git.
• There are no Claude/Anthropic authors or Co-authored-by trailers.
• The contributors API only returns Jwz-git:
  https://api.github.com/repos/Jwz-git/my-knowledge-base/contributors
• The Contributors graph also only shows Jwz-git:
  https://github.com/Jwz-git/my-knowledge-base/graphs/contributors

Only the repository homepage sidebar still shows "claude".

Could GitHub staff please rebuild or invalidate the stale contributor sidebar index for this repository?

Your evidence points pretty strongly to a stale repository-homepage sidebar cache rather than real Git history attribution.

The important checks are the ones you already did:

current default branch commits -> only Jwz-git
contributors API -> only Jwz-git
Contributors graph -> only Jwz-git
homepage sidebar -> still shows claude

Those surfaces are not always backed by the same cache/index. The Contributors graph and contributors API are closer to the commit history view, while the repository homepage sidebar can lag or hold stale repository metadata longer.

A few low-risk things that sometimes nudge repository metadata recalculation:

1. Push a normal small commit to the default branch, or an empty commit if you are comfortable doing that:

   git commit --allow-empty -m "Refresh repository metadata"
   git push

2. Temporarily edit repository metadata that affects the homepage, such as the description/topics/homepage URL, save it, then restore it.

3. Confirm there are no tags/releases/branches still pointing to old commits authored by claude:

   git fetch --all --tags
   git log --all --format='%an <%ae>%n%B' | grep -i claude -n

   The contributors API usually focuses on the default branch, but checking all refs helps rule out an old branch/tag confusing a UI cache.

4. Check whether the sidebar changes in a logged-out/private window. That separates browser/CDN cache from the repository metadata itself.

If all refs are clean and the sidebar is still stale after another default-branch push, I do not think there is a public API to force-rebuild just that homepage contributor sidebar. At that point Support/GitHub staff would need to invalidate or rebuild the repository metadata cache. I would include exactly the comparison you listed, because it shows this is not a commit-attribution problem:

• repo URL
• contributors API URL returning only Jwz-git
• contributors graph showing only Jwz-git
• screenshot of homepage sidebar still showing claude
• output of the all-refs grep if it finds no claude authors/trailers
