@@ -346,3 +346,7 @@ Every cold sample has `waterfalls`: proxy request order/start/headers/end times
and page Resource Timing discovery/start/end times. Proxy times start when
tracking begins; page times start at navigation. Compare within each clock,
then use the page FCP to locate the rendering dependency.

response in every cold sample, including worker installation. Omit this assertion
