How many CONSECUTIVE frames isGrowing must hold before a bin confirms — the
time-domain tiebreak for the one shape a single window cannot judge (issue #106): a
smooth musical crescendo. Within one window a +6 dB swell (live corpus: a C6 at
1 049 Hz, [-53.7, -51.4, -50.4, -48, -47.3]) is indistinguishable from slow
feedback — the difference is only visible on the NEXT hop, where a crescendo peaks
and plateaus (the window's rise collapses) while feedback keeps climbing. Requiring
the gate to hold twice in a row costs a clean ramp nothing — its gate is already true
while persistence is still arming — and blocks the swell that peaks the very frame it
would have confirmed.
