Case contract

Input {'items':[[lb,arm]],'main_arm','nose_arm'}. CG at or aft of the main gear -> ['TIP', CG r2]. Otherwise nose reaction = W*(main-CG)/(main-nose), main = W - nose; status 'LIGHT_NOSE' if nose < 5% of total weight else 'OK'. Return [status, nose r1, main r1].

Why this case matters

Ground stability depends on the split of weight between nose and main gear; a CG over or behind the mains tips the aircraft onto its tail.
