The final month takes what the months before leave, spread over its days; a disposed asset stops on its disposal day. A skipped month is caught up in the month the run is made; a reversed run un-posts its month. New schedules spread by day; equal-months schedules must start on the 1st. Amounts round to the currency's own minor unit. Kani and Lean proofs; an exhaustive search over runs, reversals and disposals.
