Two channels, one pipeline. Live is your phone's real frame-interval jitter. Control is manufactured noise with the same mean and spread — nothing is hiding in it. If both show ghosts, neither is evidence.
real frame intervals, no permission required
synthetic Gaussian noise, matched variance — the null
2000 runs of pure noise through this exact pipeline put the top peak at 2.74× the floor on median and 3.80× at the 99th percentile. Below 3.22 is what noise does by itself. Nothing here ever earns LIT — a periodicity in timing is an echo, never the bus.
