Compute the bill under a linear, 2-part, or 3-part tariff

I give a usage volume and a tariff schedule and get the exact amount owed, with the right block selected and overage applied only above included units.

You receive: A pure function computing {blockIndex, platformFee, unitCharge, overageCharge, total} from a block schedule and a usage figure, graded on hidden input->output cases.

What's verified: STUD verifies the billing function selects the correct block (the first block, ascending by included units, whose bound covers the usage; above the top bound the top block applies) and computes the fee, per-unit, and overage charges exactly against hidden usage cases. STUD does NOT verify that the tariff is well designed or that the usage figure is what a real customer would consume.
