A multi-step verifiable reasoning benchmark that evaluates whether models can solve pencil puzzles with unique solutions. Every genuine source row stays tied to its exact model label, configuration, benchmark version and evaluation system. The summary chart shows one best compatible score per canonical product; Score 2.0 admits only explicitly mapped, frozen protocols and keeps incompatible configurations separate.
