Clear the court of everything that is neither the puzzle nor the threat

"remove the mob boy - make the normal zombies rarer and not so close to the
color gang".

sendBoy refuses during a drill, guarded at the function rather than at the
call sites — same shape as its existing G.interlude guard, so every present
and future caller inherits it. He is one more body crossing the lanes you are
reading colours down, and unlike everything else out there he is neither the
puzzle nor the threat. Measured: 0 boy-frames in 90 seconds. Gore no longer
gets mopped in this mode; the existing 40/30 caps are what bound it.

The eaters are rarer — every 12s falling to 5s, capped at 3 on court. At the
old rate they were a second crowd rather than an interruption, and a threat
you break off to deal with only works if breaking off is occasional. 8
arrivals in 90s where the old numbers gave ~13.

And they enter wide of the colour gang: best-of-9 lane sampling against the
bibbed bodies, the same trick the batch uses. Narrowest clearance measured
across 8 spawns was 0.91 m. They still converge on you afterwards — that is
what they are for — this only decides where they walk in, so they stop
screening the bodies you are trying to read.
