feat: troops & armies (existence phase, no combat) - #12
Merged
Conversation
Add troops and armies as a new 5th actor kind. Barracks train troops (4 tier-1 types) which spawn as armies at the barracks tile; armies carve out a capped military share of city population, add food upkeep to the nearest owned city, march tile-by-tile with 8-directional (Chebyshev) movement, and can merge when co-located. Combat is out of scope. - domain.Army + TroopType; constants troop stat table + barracks training capacity + MilitaryPopulationFraction - armies table (JSONB troops) with sqlc queries + write-behind flush - proto: ArmyId/TroopType, Army/TroopStack, EntityBag armies, ArmyService - army actor: create/get/move/merge/delete, movement ticker, nearest-city upkeep attribution, tile occupancy - barracks producer: FIFO per-barracks training queue + completion timer - city: MilitaryPopulation reserve/release, army upkeep map, civilian + army food upkeep in the food tick - tile army occupancy; stream/GetMap/StreamState army wiring; setup restore
…ev script GetArmy now bypasses the vision check when the caller owns the army, so a player can always inspect an army they've marched out of sight (ListArmies already returns all owned armies). Adds scripts/troops.py, a Connect JSON-over-HTTP helper to exercise ArmyService locally without grpcurl.
