One-command drift detection. Composes audit-list + oia-audit + audit-trend into a single primitive — finds the most recent audit in `metaharness-audit` namespace, runs a fresh audit against the current repo, diffs them via ADR-152 §3.1 similarity, and alerts when structural distance crosses `--threshold`. Iter 53 of ADR-150 deep integration.

From the source SKILL.md

The natural ops question after running oia-audit weekly is "did anything drift?" Before this skill, the answer required a three-step sequence:

npx ruflo metaharness audit-list --format json   # → pick a key by hand
npx ruflo metaharness oia-audit --format json > /tmp/curr.json
npx ruflo metaharness audit-trend \
  --baseline-key <picked-key> --current /tmp/curr.json \
  --alert-on-distance-below 0.95
