Realms stop coexisting peacefully and go to war. Unlike the derived Steps 3-4,
war is stateful & path-dependent, so it adds saved state (allegiance + wars +
a war RNG), extends the step-back snapshot, and bumps the save to v21.
- PlanetConflict.{hpp,cpp}: stepConflict(year) runs once per sim year. Neighbouring
realms (adjacency by settlement proximity) grow hostile from ambition (size gap)
+ ideology (culture/faith difference) + contested frontier + a yearly streak, and
declare wars (cap warMaxConcurrent). Each war-year runs a battle (strength =
totalPop x Warlike bonus x defender home advantage), inflicts casualties on
frontier cities, and the winner conquers a loser frontier city (allegiance flips
to the victor) or sacks it (ruins). Conquered foreign/distant cities revolt over
time; a realm that loses its capital collapses -> empires rise and fall. Separate
sWarRng keeps tectonics deterministic.
- computeTerritory() honours sSettleAllegiance (overriding the mono-cultural rule)
with a chain-resolving capital lookup, so borders move as cities change hands.
- Save v21: allegiance + wars + war RNG (new hasConflict readState param + a
per-frame block in the step-back history); WeatherSnapshot + capture/restoreWeather
extended, so ,/. rewind conquests + revolts.
- Render: red war-front lines + a red at-war marker & active-wars list in the Realms
tab over the Territory view (P), a cell-info AT WAR flag, a HUD war count, and
kind=5 events (declare / capture / sack / revolt / peace).
- war* config knobs; test_conflict.cpp covers wars erupting, conquest moving the
border, revolts, determinism, RNG isolation, save-v21 + snapshot round-trip.
All 13 suites green.
