Recover a file Claude Code overwrote

Claude Code edited or overwrote a file and you need a previous version, but the project has no git history for it.

Claude Code keeps per-session file snapshots.

1. Look in ~/.claude/file-history/{session-id}/ — find the session folder by date.
2. Files are stored as {sha256(absolute-path)[:16]}@vN — hash the file's absolute path to locate its snapshots.
3. Copy the @vN version you need back into place.
