Caller-declared incompatible cargo groups on delivery vans. Two cargo groups in a caller forbidden pair must never share an active route. No hazardous-material legal assessment. Uses the paid-qualified existing VRP planner unchanged, then checks this business rule against the actual proposed route. A rule violation yields dispatch_ready=false, never an assertion that the extra constraint was optimized.

Takes a kind 9735 receipt directly or fetches it from relays by event id, then runs eight named checks and reports each one separately with its reason. The receipt signature and the signature of the zap request enclosed in the description tag are verified per BIP-340. The invoice is decoded and its amount is compared against the amount tag of the zap request, since those two can disagree and only the invoice was payable.

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.
