- 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

- ProcessItem: disk read/write rate + cumulative bytes, energy-impact score,
executable path; equality now tracks energy/disk so the table refreshes
- ProcessMonitor: disk I/O + idle-wakeup rates from rusage_info_v4; full path
capture; on-demand KERN_PROCARGS2 args + PROC_PIDLISTFDS open-file count
- EnergyModel heuristic + pure ProcArgs parser (both unit-tested)
- ProcessView: sortable Energy + Disk I/O columns (icon folded into Name to stay
within SwiftUI's 10-column limit); Get Info (double-click / ⌘I) opens inspector
- ProcessInspectorSheet: live stats, path, args, open files, Reveal/Copy Path
- 10 new tests (32 total green); smoke: stable under CPU+disk load

- MetricsStore: thread-safe on-disk ring buffer (Application Support), throttled
background saves, flush on quit/background, 24h/20k cap
- MetricsMath: pure trim + downsample (unit-tested)
- HistoryRange (Live/5m/30m/1h/24h) + HistoryRangePicker + MetricTrendChart
- Wire recording into SystemMonitor; range picker in CPU/Memory/Network tabs
- Fix durability: flush history on applicationWillTerminate + scenePhase.background
- 8 new tests (30 total green); runtime smoke: no crash, 7 samples persisted
