bernoulli_gate()

MAYAFLUX_API bool MayaFlux::Kinesis::Discrete::bernoulli_gate ( double  input, std::span< double >  coefs  )

noexcept

Probabilistic gate: each pulse passes with the given probability.

coefs: [threshold, latched, probability, state, pass]. The draw happens once per rise with xorshift32, so a clone with the same array repeats the same decisions.
