GitHub repository access check fails for CCR routines after re-authorization

Bug

When creating a scheduled remote agent (CCR) routine with a GitHub repo source, the routine fails with:

GitHub repository access check failed — re-authorize GitHub in settings reason: github_repo_access_denied

Steps to reproduce

1. Create a CCR routine with a git_repository source pointing to a valid GitHub repo
2. Connect GitHub in claude.ai settings (OAuth flow completed successfully)
3. Attempt to run the routine via API or claude.ai/code/routines

Expected behavior

Routine clones the repo and runs successfully.

Actual behavior

Fails immediately with github_repo_access_denied before the session even starts.

Notes

• Repo is public (visibility is not the issue)
• GitHub was re-authorized multiple times
• Routines without a repo source work fine
• Account is newly created (May 2026)
