  skipped by auto-assign, counts as complete, tap again to unmark
- Rule violations panel: access via wand long-press context menu when conflicts exist;
  shows all isRuleOverridden slots with Fix (clear) or Ignore (acknowledge) actions

  isPremium property tracked per session
- PremiumSyncService: extracted premium state machine, StoreKit Transaction.updates
  listener, isPremium no longer synced via iCloud to avoid stale state
