pub const LATCH_CAP: usize = 4;Expand description
How many [latch] entries one preset may declare (ADR-0137).
A chosen constant, and it is chosen rather than measured. There is no
experiment behind four: it is the number of independent armed-and-fired
events a preset can hold in one reader’s head at once, and every slot costs
every preset — declared or not — a float in Variables and a bool plus a
float in the render layer’s bank, because the block is fixed and positional.
A preset asking for more gets a load error naming this number, not a slower
path; raising it is a recompile and nothing else.
