Explorer Ship Generator

Rooms are generated from a functional inventory and packed into deck cells. Corridors and vertical trunks are reserved before room placement; reachability is checked with graph search. Hull selection is a bounded heuristic, not a proof of global optimality. Space-to-ground propulsion, reactor fuel supply, pressure-shell strength, debris shielding, independently survivable escape paths and fire/disease probabilities are not physically solved. Infeasible constraints are reported.

The watch bill follows a fixed 24-hour cycle: three 8-hour watches with staggered meal relief, eight protected sleep hours and two rest days per week. A seven-day reservation solver checks essential staffing and room capacity every half-hour. Minimum staffing, workload and 60 prepared meal portions per food-service worker-hour are assumptions. Continuous travel, watch handover time, fatigue physiology, caregiver exposure and staff casualties are not yet simulated.

Baseline consumption: 0.84 kg oxygen/person-day; 1.83 kg packaged food/person-day; 0.00472 m³ food/person-day. Model assumptions: 98% water recycling, 80% oxygen recovery, 5 kg daily water throughput, 2 noninfectious illness episodes/person-year initially. Exercise scheduling is 2.5 hours/person-day. Daytime circadian lighting targets ≥250 melanopic EDI lux; presleep 8 ± 2 melanopic EDI lux. Actual equipment and light distribution need independent design.

The outbreak scenario follows shared-room contacts in the exported schedule. Its transmission coefficients are illustrative, not a forecast. Green spaces, privacy and recreation are provided, but no validated psychological-response model is implied. This is a game-world architecture seed, not a certified spacecraft.
