# Ordo verified against Divinum Officium (Monastic Tridentinum 1617),
# 2026-08-25 run — see src/hours/prime.ts for how each part resolves.
#
# Deliberately deviates from that verified source in several places, all by
# explicit decision:
#   - The opening Pater/Ave/Credo (said silently before "Deus in adiutorium")
#     is dropped entirely, to keep the hour shorter.
#   - The Regula reading and the generic Lectio Brevis are both said, in
#     sequence — historically these are alternatives (Regula in choir, OR
#     Lectio Brevis alone outside choir), not both.
#   - A short responsory ("Christe, Fili Dei vivi") is said after the
#     chapter — Monastic Prime doesn't actually have one (it goes straight
#     from chapter to versicle); this is the Roman/secular breviary's,
#     added by choice. See hours/chapter-responsory.ts for its seasonal
#     (and eventually per-feast) variants.
#   - The Athanasian Creed is included on qualifying Sundays even though
#     Monastic Prime doesn't traditionally have it either — see
#     hours/prime.ts's 'creed' case for the inclusion rule (a deliberate
#     simplification of the real, much more tangled rubric).
#   - The Pretiosa (the versicle/response said right after the Martyrology
#     in choir) is dropped — a deliberate cut, not an oversight.
#
# The capitulum and Preces both use calendar/isSundayOrFeast to pick between
# a Sunday/feast form and a ferial form (see hours/types.ts's 'by-day-kind').
# By explicit choice, the ferial Preces are said on *every* ferial day, not
# just Advent/Lent/vigils/Ember days the way later rubrics restricted them.
#
# The dead-commemoration psalm (129, De profundis) is dropped by explicit
# choice — a deliberate time-saving cut, not an oversight. The intro/close
# responsory and collect around it are kept.
