This household as a sim. Scenario packs include grid-down, heat, water-out, and get-home. The page pulls numbers you already entered in power, vehicle, Deadstock, water, and food, then steps those stocks over time with a stay or go posture.
SITREP is the snapshot. Twin is the time-step. Run the calculators first so Twin is not empty.
It imports other tools. Run Water, Food, Power, Vehicle Profile, and Deadstock first. Empty inputs stay empty.
