A Meta-internal coding benchmark of 440 tasks derived from the Meta codebase and evaluated in an internal harness. 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.
