P2 paired A/B - per-thread CPU per frame (ms), trailing window, push - pull

pin columns: before/after verdict per run (P=PINNED, D=DRIFT = a cluster clamped by thermal management, U=UNPINNED) @ cpuss temperature C p50/p99: the runner's best-of-N repeat (lowest mean wall frame time), trailing tailFrames window, device median rule / nearest-rank p99; 'best' says which repeat
