Detailed Description

template<class Model>
struct pops::detail::InvStabilityDtKernel< Model >

InvStabilityDtKernel: max over cells of 1/model.stability_dt.

We reduce the INVERSE (a frequency) because the seam only provides a MAX reduction initialized to 0 (reduce_max_cell): min(dt) == 1/max(1/dt) for dt > 0. A stability_dt <= 0 or non-finite is ignored (does not constrain) – the model signals "no bound here" by returning +inf.
