how it works
Each metric carries a Rate in minor units per unit. Your usage becomes a Quantity, and price(quantity, rate) rounds once, half-to-even, keeping the exact pre-rounding value (the exact ¢ chip). Settling builds an accrualPosting: customer_balance +X / revenue_accrued −X, asserted to net to zero before it is ever recorded.
