qualifier number + unit a measured amount

access expiry

How long access to a digital delivery lasts before it expires — the structural bound, a numeral with a time unit (TimeUnits: days, weeks). A qualifier of `delivery_method` (cardinality one): a streaming-access or cloud-activation delivery often grants time-boxed access ('30 days'), whereas a perpetual download has none. The policy duration only; the realised expiry date is computed downstream from the purchase moment (A10/L1).

Access expiry is a measured figure, given in seconds or minutes.
