Sampling Methodology

Component	Method	macOS Support	Privilege	Accuracy
CPU	Native host_processor_info()	All	none	✅ exact
GPU	IORegistry heuristic (AppleARMPMUPowerSensor)	Apple Silicon 11 → 26 Tahoe	none	⚙️ approximate
ANE	IORegistry heuristic (H11ANE)	Apple Silicon only	none	⚙️ approximate

The app does not use powermetrics or any privileged samplers.

Verification Status

✅ Verified – Git repository public and up to date.
✅ Verified – IORegistry sampling fully functional.
⏳ Pending – Homebrew cask and code-signing.

Roadmap

1. Preferences: refresh rate, theme, position lock
2. Packaging: signed .app + Homebrew cask
3. Optional: per-core CPU display
4. Optional: network / memory panels
