Does libn4m match its reference — and do all bindings match the core?

Every method, every language binding, every problem size. Each method answers two distinct questions: binding parity (do Python / R / MATLAB match the C++ core?) and reference parity (does the C++ core match the canonical external library?). Search, filter, and drill into timing curves and the full multi-reference table — or open the full parity matrix for the methods × implementations grid.
