`.gitattributes` declares `*.py text eol=lf` and `*.sh text eol=lf`, but 74 files (73 .py, 1 .sh) are stored in the index with CRLF line endings, violating that contract. Every macOS/Linux clone reports these files as "modified" on fresh checkout because git's diff engine sees the stored bytes don't match the attribute contract, even though the working tree and index match byte-for-byte. Running `git add --renormalize .` rewrites each affected blob so the stored form matches the attribute declaration. No semantic changes — every affected file's diff is "N insertions, N deletions" with inserts and deletes being the same lines modulo line endings. Follow-up commit adds `.git-blame-ignore-revs` so `git blame` / GitHub blame skip this mechanical commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
