- HealthModel (pure): 0-100 score + plain-language diagnosis + rating - SystemAlert/AlertKind/AlertThresholds + pure AlertEvaluator (sustained-breach) - AlertCenter (@MainActor): per-cycle health + alert evaluation, de-dup by kind, inbox (capped), native UserNotifications on transition into a condition - Covers: sustained high CPU, critical memory pressure, disk full, thermal, runaway process, low battery - Wire evaluate() into SystemMonitor; request notif auth on launch - HealthCardView (score ring + diagnosis) + AlertsInboxView in Power & Storage; health score + alert badge in menu bar - Renamed model Alert->SystemAlert to avoid SwiftUI.Alert shadowing - 10 new tests incl. AlertCenter de-dup integration (52 total green) - Visual smoke: Energy + Disk I/O columns render with live data under load Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
