The first publicly published macOS-native computer-use benchmark. 369 task slots across 15 categories (Finder, Safari, Mail, Notes, Calendar, Reminders, Settings, Terminal, Pages, Numbers, Keynote, Music, Photos, Maps, Multi-app), agent-agnostic Go runner, dual scoring (IMPLEMENTED + STRICT), per-task PID-snapshot isolation. First reference run: kinclaw v1.15.0 + Kimi-K2.5 = 67.3% IMPLEMENTED. Documents the full 49.3 -> 62 -> 67.3 debugging trajectory as methodology contribution.
