Detailed Description

A FluidStateSpec that also exposes the adiabatic index, for solvers (e.g. HLLC) that need gamma directly rather than only through cons_to_prim/prim_to_cons/flux. Satisfied by a state-independent gamma() (a single constant adiabatic index) or a per-state gamma(prim) (e.g. a spatially/species-varying index); see get_adiabatic_index_lr() for how solvers should read it.
