helix-backup-audit-methodology-via-temp-clone
Verified pattern for auditing live skills against a GitHub backup: clone repo to a temp location (e.g. /tmp/helix-backup), run diff -rq per file, compare byte counts with du, then run fusion-invariants-lint.py against live. Clean up temp clone immediately after. This produces a reproducible, zero-ambiguity audit trail without polluting workspace state.
