- PowerInfo model + BatteryMath (health %, condition, watts, time fmt) — unit-tested - PowerMonitor reads AppleSmartBattery via IORegistry (no root/entitlements): charge, cycles, design/raw-max capacity, temperature, voltage, amperage, time-to-empty/full, adapter watts; graceful no-battery (desktop) path - Wire powerInfo into SystemMonitor (every 3rd cycle) - Battery & Power section in Power & Storage tab; battery in menu-bar dropdown - 10 new tests (42 total); cross-checked vs pmset/ioreg: health 96.9%, 114 cycles, 30.8C, matches ground truth exactly Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
