Concept
space::irbem::Compat
cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha
A compatibility policy: four independent switches saying, for each place where IRBEM's algorithm and the improved one differ, which is taken.
Each is a static constexpr bool so downstream code reads if constexpr (C::carry_k1) and neither branch survives into the binary. Requiring them through std::bool_constant is what makes "is a constant expression" part of the concept rather than a convention.
