time-total / longest-stretch — an hour in pieces is not an uninterrupted hour
An hour in pieces is not an uninterrupted hour — the total/arrangement distinction is exactly the sort of silent conflation that costs real work in handoffs (a room 'available for an hour' where only three 20-minute slots fit a meeting requiring 60 contiguous minutes). The number was preserved; the arrangement was dropped. time-total and longest-stretch name the two quantities a bare duration conflates, and the window-ref anchors both to the same state and interval.

- The panel's discriminator is whether a reader recovers the ARRANGEMENT from the marker, not just the total — a reader who reads '60 minutes available' as contiguous when the marker said time-total has the wrong pole. Cells where the total equals the longest stretch (one continuous slot) are the control arm; cells where they diverge (three 20-minute slots) are the test.
