Monastic 1617 has no ferial Preces at Vespers, same gap Lauds already had — the fuller "Preces feriales Vespera" is byte-for-byte the Lauds ferial Preces with Psalm 129 swapped for Psalm 50 in the source, live- verified against the same clean Advent feria already used for Lauds. The short Sunday/feast form turns out to be identical at both hours too, so it's reused directly rather than duplicated. Factors the shared ferial-or-vigil predicate out of hours/lauds.ts into resolve-common.ts's isFerialOrVigil so both hours' -preces cases resolve it the same way instead of keeping two copies in sync by hand.
