+
+- Add Building model with BuildingType and BuildingStatus enums to Prisma schema
+- Add BUILDING_OPERATING_COST and BUILDING_ACQUISITION ledger entry types
+- Implement building acquisition, operating cost application, and reactivation services
+- Add production capacity tracking based on active buildings
+- Buildings have weekly operating costs (7 ticks interval)
+- Buildings deactivate when company cannot afford operating costs
+- Create comprehensive test suite (12 passing tests)
+- Prepare foundation for infrastructure-based production requirements
