  "methods": [
    "Each measure reduces remaining energy demand, adds any new demand, then adds renewable supply. Renewable use is capped at demand; excess supply is curtailed. State updates use the canonical decimal input values before numeric display conversion.",

    "Annualised capex = capex / annuity present-value factor. Incremental annual cost = annualised capex + measure opex − incremental energy-cost saving.",
    "Marginal abatement cost = incremental annual cost / positive incremental annual emissions reduction. Sequence determines the attribution.",
    "Marginal abatement cost is evaluated for each strictly positive canonical decimal emissions reduction, including small positive values, without an absolute floor. A zero or negative reduction has no defined abatement denominator.",

    "Demand, supply, emissions and monetary balances use the canonical decimal representation of validated inputs. The discount annuity factor and displayed Numbers are approximations. Digits lost during JSON parsing cannot be recovered; results outside finite numeric display range are rejected explicitly. Mathematical precision does not establish measurement accuracy, materiality or reporting eligibility.",
