Record that lowering the noise floor to 8s is wrong
The 12s floor cut real detection on shows with verified ads -- LeVar
Burton Reads fell from 19.0 to 10.5 minutes found against a 26.6 minute
gap -- so 8s looked like the fix. Measured on an isolated copy of the
live data it is not: Sleepy History at 8s finds 174 minutes of
"advertising" in a show that has 48 seconds of it, worse than the 4s
floor that produced Peter's original complaint.
MinRunSamples and MergeGapMs interact and cannot be tuned separately. A
low floor lets noise fragments survive and the 60s bridging then welds
them into enormous spans.
Had only LeVar been measured the floor would have been lowered.
Also re-pins .coverage-baseline, which the hook left modified after
d96c876 deleted covered readout code.
