Cultures stop being static one-per-continent blocs. Culture identities are now stateful: the list is append-only (seeded once at the dawn, schism children appended later, records frozen after creation) and the per-settlement culture is mutable state. - stepCulture(year) in the yearly tick (pure hashes, no RNG): assimilation (a conquered settlement adopts its ruler's culture, which drops the Step-5 revolt cultBonus -> assimilation pacifies provinces), border conversion (population x trade-prestige pressure; realm capitals exempt), schism (a far-flung coherent cluster -- typically overseas colonies -- breaks away as a new people with a local-bank NameGen name and ethos/faith re-derived from its own lands). - computeCultures() became a pure derived refresh (seeds only when the list is empty); seedCultures() reproduces the old per-continent peoples byte-identically for the dawn and pre-v23 loads. - Colonies inherit the founder's culture at founding; the Step-3 mono-cultural vassalage rule is culture-matched (regionId fallback) so schism clusters found their own realms -> colonial independence wars. - Per-cell culture view colours by the owning settlement's culture, so a conquered city keeps its colour until it assimilates. - Save v23: culture identities + sSettleCulture + next-id counter, also in the step-back frames; snapshots rewind via truncate-and-replay. Pre-v23 saves re-seed on the next refresh. - Kind-7 world events; Cultures tab hides extinct peoples and shows a schism child's founding year. Knobs cult* in planet.cfg. - New test_cultevo.cpp (30 checks); all 15 existing suites still pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
