nx_caplab_cities.nx -- Capitalism Lab R6: cities + retail presence (the MAP). Capitalism Lab is geographic. Each CITY is its own market, sized by population; a firm only competes in a city where it has RETAIL PRESENCE (capacity > 0 there); a product's total sales = the sum across cities. Expanding to more / bigger cities reaches more demand. Composes R4 (quality/brand split) + R5 (per-market capacity) across geography. MODEL: city_M = base_M * population / pop_ref (bigger city = more demand) per city = split among PRESENT firms by appeal, capped by retail capacity product total = sum over cities of that firm's per-city sales nx_safety_envelope: intended_use: capitalism-lab geography (pure functions, no I/O) sil_target: SIL1 verdict: NOT_YET_EVALUATED genealogy_id: capitalism_lab_cities_map_canon lineage_id: nx_caplab_cities_v1
