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.

When Advent 4's own Sunday lands on Dec 24, the Vigil of Christmas's
identity (rank, collect, Lauds antiphons, Matins Gospel nocturn) now
governs the day, matching the reference engine's own rule that a
privileged Sunday never displaces it. Unlike the reference engine's own
"no commemoratio" for this exact collision, Advent 4 is deliberately
still commemorated — the Sundays of Advent have real standing of their
own. Matins' three-nocturn Sunday psalmody is untouched either way,
since it's driven by weekday, not by which id wins.
