Share publicly disclosable structures, observations, and method limitations. No actual professional responses are available yet.

Which power / temperature values are measured, estimated, or unobservable by layer?
How are timing, cooling / TIM boundaries, and stack models calibrated?
Can switching be replayed with other loads / throttling fixed to compare cross-location responses?
