Every temporal id had its Lauds (Benedictus) antiphon authored, but only
3 of 57 had the Vespers (Magnificat) counterpart -- a whole-calendar
gap exposed by 2026-08-29's Vespers rendering with no Magnificat
antiphon at all. Sourced from the reference engine's static Tempora/
Sancti files, same convention and per-id reference dates already
established for the Benedictus antiphons.
advent-4 and marian-saturday are the only two ids still missing one
(neither resolves from the static files alone) -- follow-up commit.
