-// CollapseRecurringSeries reduces each recurrence series to its single
-// earliest-due instance, preserving input order otherwise.
-//
-// The scheduler deliberately materializes a series' next instance once the
-// current one comes due, whether or not it was completed, so that ignoring one
-// occurrence doesn't stall the series (see
-// GetSeriesNeedingNextIteration). The side effect is that an unfinished
-// recurring chore and its already-generated successor both sit in the flat task
-// list at once -- "Bills" appearing twice, once overdue from Sep 1 and once for
-// Oct 1. Only the earliest open one is a thing you actually owe right now.
-//
-// This is for flat "what's open" views only. Date-anchored views (timeline,
-// widget) should keep every instance, since there each one legitimately belongs
-// to its own day.
