Recover from Corrupted Git State
When bulk git operations (large commits, background pulls, rebases) fail or leave stale state: (1) Check for lock files and background processes (ps aux | grep git); (2) Detect corrupted rebase state via rebase-merge directory — abort with git rebase --abort and switch to merge; (3) If pre-commit hooks block large files, unstage oversized files and recommit selectively; (4) For untracked file conflicts during pull, move conflicting files to /tmp, pull, then restore; (5) Always verify final state with git status and divergence count (should be 0/0 after sync).
