Here is a list of all documented concepts with brief descriptions:

[detail level 123]

Nsham	Namespace for backends this one is named only sham since shambackends is too long to write
Ndetails
Rkernel_invocable
Nshamalgs	Namespace to contain everything implemented by shamalgs
RHasCustomDefaults	Detects whether Alt opts into exposing more than one default instance of itself (e.g. the same alternative with different tunable field values) via a static variant_custom_defaults() method, for example:
Nshambase	Namespace for basic c++ utilities
Ris_mdspan
Ris_mdspan_rank
Rsame_mdspan_value_t
Nshammath	Namespace for math utility
Ndetails
RHasGlobalGamma	True if T exposes a single, state-independent adiabatic index via gamma()
RHasPerStateGamma	True if T exposes a per-primitive-state adiabatic index via gamma(prim)
RFluidStateSpec	An equation of state paired with the flux/wave-speed operations a Riemann solver needs, so that solvers (see riemann_rusanov.hpp, riemann_hll.hpp) can be written once and instantiated for any fluid state satisfying this interface
RDustFluidStateSpec	The flux operations a dust (pressureless) Riemann solver needs, so that solvers (see riemann_dust_hll.hpp, riemann_dust_huang_bai.hpp) can be written once and instantiated for any dust state satisfying this interface. Analogous to FluidStateSpec but without an equation of state, hence no sound_speed()
RFluidStateAdiabaticSpec	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
Nshamrock	Namespace for the main framework
Nsolvergraph
RJsonDeserializable	Concept for types that can be registered for polymorphic JSON deserialization
