`is_consteval` and the `static_prop` concept split one question into two checks that every call site had to run in sequence, once to confirm the member had the exact declared type and again to confirm its value was a constant expression. `static_prop_probe<T, V>` answers both at once. Passing `X::member` as an `auto` non-type argument already requires a constant expression, and `is_same_v<T, decltype(V)>` pins the type exactly, since `auto` deduction drops the `const` that an implicit conversion would otherwise hide. Each call site loses a nested `if constexpr`. `is_is_direct_well_formed` reduced to a single requirement and folded into the `requires` blocks of `basic_convention` and `basic_reflection`, its only two callers.

is_constevaland thestatic_propconcept withstatic_prop_probe<T, V>, which answers in one requirement what previously took two sequential checks. PassingX::memberas an auto non-type argument already demands a constant expression, andis_same_v<T, decltype(V)>pins the type exactly, sinceautodeduction drops theconstthat an implicit conversion would otherwise hide.No functional changes.
