# Git Blob Size Filter Cleanup
When a file (e.g., `cost-tracking.jsonl`) grows beyond 100 MB in unpushed commits and blocks GitHub push, use `git filter-branch` to strip the oversized blob. Add the file to `.gitignore`, then run `git filter-branch --tree-filter 'rm -f <filepath>' HEAD~N..HEAD` to rewrite commits. This is safe only for unpushed commits not yet in origin. After rewriting, commit the `.gitignore` change and push normally.
