helix-backup-vs-live-audit-method

To audit helix GitHub backup vs live /root/.claude/skills/: clone repo to /tmp/helix-backup, run diff -rq for file-path identity verification, byte-level comparison per file for content, then run fusion-invariants-lint.py. Clean up /tmp/helix-backup immediately at audit close. 107 identical + 14 enhanced + editorial compression is the expected healthy distribution.
