## Difftest (Rust vs C++)

The C++ reference build requires Bash, CMake 3.20 or newer, and a C++17 toolchain.
Ninja is optional: when absent, CMake uses its default generator (typically Unix
Makefiles, which requires `make`). Linux with GNU C++ is the parity reference used
in CI; shell compatibility on macOS does not establish Apple-Clang difftest parity.
