Drift detection
Conditional Access policies are snapshotted on every resync and nightly backup. Drift is compared to the tenant's chosen comparison baseline (imported snapshot by default) with per-policy diffs.
- Snapshots on every resync - unchanged policies do not create noise
- Per-policy diff against the tenant comparison baseline (imported snapshot or workspace baseline)
- Critical drift on the dashboard; warnings on tenant detail
- Portal-side edits surfaced on manual resync or nightly backup
