keepsOwnSecondVespers used a fixed duplex-2-classis floor on today's rank
alone, so a lower-ranked but still-real sanctoral winner (e.g. Simplex)
tomorrow could still steal First Vespers from a higher-ranked-but-below-the-
floor winner today (semiduplex St. Raymond Nonnatus losing to simplex St.
Giles on 2026-08-31). The real "De Concurrentia Officii" rubric compares the
two days' ranks directly, with ties going to tomorrow — replace the floor
with that comparison when both sides have a real sanctoral winner, keeping
the floor only as a fallback against a plain Sunday.
