Yes. For pure-JS hot paths, literal instruction counts: run the benchmark under Valgrind with node --predictable and compare to a checked-in baseline — one run, no statistics needed. For browser paths there's no instruction counting under Chromium, but there's a ladder of other deterministic counts: React commits per interaction, function call counts from V8's precise coverage, layout and style-recalc counts, DOM mutations. Which do you want first?

please prove that hill climbing against each of these can result in measurable wall clock perf wins. we'll unship the benches for any candidates that cannot prove that

Found it in your recording — it is Chrome's resizing the page, not the handoff from the static composer to the real one (that measured 0 px on all 49 of your loads today).

Right, today's rig ticks at 60 Hz because headless Chromium does by default. I believe it can be driven at 120 (uncapped) via vsync or DevTools frame control) — confirming that first, then I'll re-run the eval against an 8.3 ms frame budget. Update on the 120 Hz rig: it works. Deterministic 120 Hz frame stepping in headless Chrome via DevTools begin-frame control — exactly 240 frames for 240 begin-frames at 8.33 ms, so "did this frame fit the 120 Hz budget" becomes an exact read rather than a noisy one.
