ical.sx parses VEVENT/VCALENDAR text back into events (ev/ical-lines->event,
ev/parse-vcalendar): DTSTART/DURATION/RRULE (ordinal BYDAY, BYMONTHDAY, UNTIL/
COUNT/INTERVAL) + EXDATE/RDATE. Round-trip is occurrence-exact — export->import
expands to the identical occurrence set. Completes bidirectional interop.
360/360 green.
