The four closed recurrence shapes computed in the definition's own IANA zone,
a fourteen-day materialisation horizon with projections beyond it, series as a
managed thing, and the admin calendar that replaces the plugin this feature
exists to replace. An event now happens on its own.
No schema change: Phase 1 built every column this needed.
- events/recurrence.js is the ONE place an occurrence is computed, so the
runner's expansion and the calendar's forecast cannot disagree. No date
library added — Node ships the tzdata one would vendor, behind Intl.
- The runner's materialise leg is now two halves: expand, then sweep. The
window starts at `now - grace`, so an occurrence nobody could have seen is
never invented retroactively; the horizon is what makes the missed sweep
mean anything for a recurrence.
- Publishing is the schedule switch and archiving turns it off, and publishing
re-pins every occurrence that has not started.
- A projection is never drawn over an instant a run occupies, so a cancelled
occurrence does not reappear as a forecast.
54 new tests, incl. the DST fixture set the plan asked for and three new
statements proved against a real MariaDB. Suite 1768/1711/56 skipped/1 fail
(pre-existing CRLF). Walked end to end on the local review stack.
