literally put an integrating current sensor in your device & reset it every time you task-switch

But what if I heat up the cpu to just below fan activation and trick the next process into cooling for me?

if you mean "how do I exclude current used by autonomous cooling system", then you route it around the sensor :)

Delayed kernel tasks/delayed anything? So many power using hardware components I could establish a causal relationship with.

another (somewhat contrived) example: I display a dialog, causing the user to reach for the touchpad, waking it in the process.

touchpad wouldn't be counted towards task usage. the only two hard cases here are non-timeshared resources & asymm. multicore

"asymm multicore" maybe solve with exclusive timesliced execution? Assuming you have the non-timeshared resources pinned down.

I mean more like, how do you attribute SATA GC? Or cellular baseband.

Yeah exactly the problem. But let's assume you have the measurement pinned down, maybe within tolerance in a relaxed model (ct)
Replying to
you could give processes a budget and have them participate in an auction for resources to incentivize low resource usage.

(I think AWS kinda does that? Just bill you for everything? It works at this level.)
