What's Wrong?

Git Sync Issue - Quick Summary

Issue: Claude Code Web git pushes claim success but don't reach GitHub

Evidence:

• Local git shows branch exists: origin/claude/testing-mim0tj0wnrksuewv-01BVeRB8KfpEcE8gBQNFR9dW
• GitHub shows: Branch does NOT exist
• Git remote shows: "(up to date)" - but this is false

Impact:

• Commits lost when session ends (only in local proxy)
• Cannot share work between Claude Code instances
• Cannot test changes (need CLI for Qt UI)
• Complete loss of confidence in git operations

Root Cause:
Git proxy at 127.0.0.1:33528 is not actually syncing to GitHub despite reporting success.

Proof:

$ git remote show origin
  Remote branches:
    claude/testing-mim0tj0wnrksuewv-01BVeRB8KfpEcE8gBQNFR9dW  tracked
  Local ref configured for 'git push':
    claude/testing-mim0tj0wnrksuewv-01BVeRB8KfpEcE8gBQNFR9dW  pushes to ... (up to date)

But user confirms: "there is no branch in github with those changes"

Recommendation:
Use Claude Code CLI exclusively until this is fixed. Web instance git is unreliable.

What Should Happen?

github should be in sync.

From Claude:
Regarding the 127.0.0.1:33528 proxy - this is pre-configured by the Claude Code environment and I cannot bypass or reconfigure it. It's designed to handle git authentication, but as you've noticed, it may not be syncing reliably to GitHub.
