Nocturn 3 previously dropped the bare "Et réliqua" Gospel incipit and kept only the patristic homily, so the Gospel citation and text never appeared. Authors the full pericope before the homily for advent-1 through advent-4 and christmas-octave-sunday, sourced from the reference engine's Missale Gospel files. Authoring Advent 4's Gospel surfaces a genuine second Matins Gospel on the rare Dec-24-as-Advent-4 collision (2023/2028), so the affected test now expects both readings instead of one.
