Fits ordinary least squares to log radiance by year, converts the slope to annual radiance change, and applies a caller-supplied economic elasticity. Night lights are an imperfect proxy affected by sensors, saturation, electrification, outages, policy, and conflict; this is not an official economic statistic or causal estimate.

Subtracts committed liabilities at month zero, then projects recurring inflow and operating outflow with caller-supplied monthly growth rates. It is a scenario calculation, not a forecast of prices, token liquidity, exchange rates, or future governance decisions.

Iterates a deterministic daily stock-flow model with a fixed source, fixed sinks, and percentage-of-current-supply sinks. It clamps supply at zero and reports each day; it does not model player adaptation, market prices, distribution, or causal behavior.
