Could you build this?
Partial The tray UI and battery/WMI readouts are vibe-codeable. Accurate CPU package power via RAPL, plus NVML GPU telemetry, requires low-level hardware access and driver-level knowledge that is hard to get right.
What it would actually take: The UI and Windows tray app are standard. The hard parts are reading Intel/AMD RAPL energy counters (which may need privileged MSR or driver access) and correctly attributing power across CPU and GPU, plus validating against hardware. This needs Windows driver or hardware-telemetry expertise and test hardware.
