nx_rewards.nx -- LIB: REAL-REWARD gamification (operator: "we want gamification for lots of these popular activities but not dumb rewards but real rewards and real positives and real capabilities"). A GENERAL gamification substrate (works for ANY activity -- swap, garden, compost, cook, ...) where every reward is REAL, never a meaningless point or cosmetic badge. A reward is REAL iff it pays out in at least one of: VALUE -- measured money saved / value gained (cents, grounded in real data e.g. store prices). CAPABILITY -- a real unlocked ability the ecosystem HONORS (rw_can gates real features on it). PROVISION -- a real good earned (seeds, a tool), with its real worth. ANTI-DUMB BY CONSTRUCTION: rw_def_achievement REFUSES any achievement with no real backing (value<=0 AND no capability). So a "dumb reward" cannot exist in the system -- proven mechanically, not promised. Sovereign seg-store (knowledge/store/reward-*, NO TSV), integer cents. license_tier: ORIGINAL
