Ordo is Monastic 1617 as a base, with deliberate Tridentine 1906 additions: the "In manus tuas" short responsory, the Nunc Dimittis with its "Salva nos" antiphon, the fuller Preces (Monastic's own is shorter), and Lent's "Christe, qui lux es et dies" hymn replacement (English translation marked draft, pending a real historical one). Psalms 4, 90, 133 are fixed daily with real verified text, unlike Prime's weekday-rotated psalms. The closing Marian antiphon now picks Alma Redemptoris Mater / Ave Regina Caelorum / Regina Caeli / Salve Regina by real season, using the calendar work from the previous commit — except Ave Regina Caelorum's own window (Candlemas through the day before Maundy Thursday) doesn't align to any single season value, so that one case checks the real date directly instead of going through the by-season table. resolve-common.ts extracts the resolve/status/doxology/antiphon helpers Prime already had into something Compline can share; a few propers files lose their "prime-" prefix now that both hours use them.
