    "PV lifecycle cost includes acquisition at t = 0, replacements at each service-life multiple strictly before the horizon, annual opex, escalated energy and downtime, less supplied horizon residual.",
    "Energy price in year 1 equals the input price, then compounds annually.",
    "Equivalent annual cost divides lifecycle PV by the ordinary annuity present-value factor.",
    "Savings hurdle divides incremental fixed lifecycle PV (acquisition, replacements and residual) by the annuity factor. Positive values require that much annual operating saving.",
    "Bid totals are ordered by their computed lifecycle present value. A tie warning applies only to the same computed value, with a stable name ordering.",

    "Discounted costs use floating-point arithmetic. A computed tie can result from numerical precision and does not establish exact economic indifference or substantive procurement equivalence.",
