詳しく見る →Earth-domain reasoning grounding for arifOS. Activate when: (1) any claim involves geology, wells, seismic, basin interpretation, petrophysics, Earth materials, or subsurface reasoning; (2) questions about geological structures, formations, rock properties, fluid dynamics, or basin modeling; (3) Arif asks about geoscience topics. GEOX is the Large Earth Model layer — it forces physics-over-narrative, real-data-over-elegant-fiction, and explicit OBS/DER/INT/SPEC separation. NOT optional decoration.
