nx_game_companion.nx

nx_game_companion.nx -- the OWNERSHIP core of the beat-Veloren companion-collector. The research (SDT + operator's pillars, gamebench round 14) says Veloren wins on AUTONOMY but has no OWNERSHIP; the endowment effect (Pokemon) is the pillar we can build because our certified parts already hold its substrate. This part composes them into a companion whose OWNERSHIP is STRUCTURALLY REAL and MEASURABLE: - UNIQUE by construction (a per-companion rolled trait vector; no two alike -- the IV/nature equiv), - PERSISTENT (rides nx_gamesave bit-exact -- what you own does not evaporate), - INVESTMENT-DIVERGENT (nx_rpgstats: what you pour XP into grows distinct -- the IKEA effect), - individually addressed (nx_entity_store handle=index+generation; a companion is a THING, not a row). ⚠HONEST SCOPE: these are the measurable PREREQUISITES for the endowment effect, NOT the psychological bond itself (unmeasurable). A game can have all three and still feel hollow; but a game LACKING them cannot produce ownership at all -- so they are necessary, gate-able, and red-teamable. LIB, no main. license_tier: ORIGINAL
