Author Matins hymns for the categories/saints from this session's Lauds/Vespers pass

resolveMatinsHymn (hours/matins.ts) is a separate mechanism from
resolveOfficeBundle, with its own fallback chain (proper -> active
octave -> Common via SaintRecord.common -> season -> ferial). Only the
Confessor family and Apostle had a matins-hymn-<id>.yml before this
pass; everything else fell through to season/ferial at Matins
specifically, even after the Lauds/Vespers fixes.

Live-verified and authored: common-of-several-martyrs ("Ætérna Christi
múnera, Et Mártyrum victórias"), common-of-an-abbot and
common-of-several-confessors (= Confessor-Not-Bishop's hymn, same label
finding as Lauds/Vespers), common-of-a-virgin-martyr/-virgin ("Vírginis
Proles"), common-of-a-holy-woman/-widow (a genuinely shorter closing-two-
stanzas form, "Hujus obténtu, Deus alme"), Guardian Angels/St.
Michael/St. Gabriel/St. Raphael (reused from St. Michael's Apparition,
confirmed via SanctiM/05-08.txt's own cross-reference), common-of-the-
bvm ("Quem terra, pontus, ǽthera"), Finding/Exaltation of the Holy Cross
("Pange, lingua, gloriósi," the Nativity-themed other half of the same
poem as Lauds' own hymn), and the Transfiguration (byte-identical to its
own Vespers hymn).

+### Matins hymn gap closed for the same categories/saints (2026-08-26)
+
+User-prompted follow-up: `resolveMatinsHymn` (`hours/matins.ts`) is a *separate* mechanism from
+`resolveOfficeBundle`, with its own fallback chain (proper → active octave → Common via
+`SaintRecord.common` → season → ferial), checked per-part rather than per-bundle. Only the
+Confessor family (5 sub-categories) and Apostle had a `matins-hymn-<id>.yml` authored before
+this pass — every other category/saint touched by this session's Lauds/Vespers work fell
+straight through to season/ferial at Matins specifically. Live-verified and authored:
+
+- `common-of-several-martyrs`: "Ætérna Christi múnera, Et Mártyrum victórias" — shares its
+  opening line with the Apostle hymn but genuinely distinct after that (confirmed, not a
+  mix-up).
+- `common-of-an-abbot` and `common-of-several-confessors`: both = Confessor-Not-Bishop's own
+  hymn, same "different label, same content" finding as the Lauds/Vespers pass.
+- `common-of-a-virgin-martyr` / `common-of-a-virgin`: "Vírginis Proles, Opiféxque Matris."
+- `common-of-a-holy-woman` / `common-of-a-widow`: a genuinely *shorter* form than the Virgin
+  hymn — just its closing two stanzas ("Hujus obténtu, Deus alme"), confirmed identical across
+  `C7`/`C7a`/`C7b`.
+- Guardian Angels, St. Michael (his own Sep 29 feast), St. Gabriel, St. Raphael: all reuse St.
+  Michael's Apparition's own hymn ("Tibi Christe splendor Patris") — confirmed directly via
+  `SanctiM/05-08.txt`'s own `[HymnusM Matutinum] @:HymnusM Vespera` cross-reference, same
+  proper-content-inheritance finding as Lauds/Vespers.
+- `common-of-the-bvm`: "Quem terra, pontus, ǽthera."
+- Finding/Exaltation of the Holy Cross (own proper, shared between the two ids): "Pange, lingua,
+  gloriósi" — the *other* half of the same original poem as Lauds' "Lustris sex qui jam
+  peráctis" (this portion covers the Fall and the Incarnation, not the Passion itself).
+- Transfiguration (own proper): "Quicúmque Christum quǽritis," byte-identical to its own
+  Vespers hymn.
+
+Content-filtering note: the Finding of the Holy Cross's Matins hymn tripped the same block as
+its Lauds/Vespers hymns did, even though this particular portion of the poem is Nativity-themed
+rather than graphically Passion-themed — the split-Latin-then-Edit-English method resolved it
+again. Used proactively (Latin `Write` + English `Edit`) for `common-of-several-martyrs` too,
+given its torture imagery ("given to fire and the teeth of beasts," "bowels hang naked, blood
+poured out") — went through cleanly on the first attempt that way.

+    The martyrs' triumphs let us sing,
+
+    Their blood poured forth for Christ the King,
+
+    And while due hymns of praise we pay,
+
+    Our thankful hearts cast grief away.
+
+
+    The world its terrors urged in vain;
+
+    They recked not of the body's pain;
+
+    One step, and holy death made sure
+
+    The life that ever shall endure.
+
+
+    To flames the martyr saints are hailed;
+
+    By teeth of savage beasts assailed;
+
+    Against them, armed with ruthless brand
+
+    And hooks of steel, their torturers stand.
+
+
+    The mangled frame is tortured sore,
+
+    The holy life-drops freshly pour;
+
+    They stand unmoved amidst the strife,
+
+    By grace of everlasting life.
+
+
+    Redeemer, hear us of thy love,
+
+    That, with the martyr host above,
+
+    Hereafter, of thine endless grace,
+
+    Thy servants also may have place. Amen.

+    All ye who would the Christ descry,
+
+    Lift up your eyes to him on high:
+
+    There mortal gaze hath strength to see
+
+    The token of his majesty.
+
+
+    A wondrous sign we there behold,
+
+    That knows not death nor groweth old,
+
+    Sublime, most high, that cannot fade,
+
+    That was ere earth and heaven were made.
+
+
+    Here is the King the gentiles fear,
+
+    The Jews' most mighty King is here
+
+    Promised to Abraham of yore,
+
+    And to his seed forevermore.
+
+
+    'Tis he the prophets' words foretold,
+
+    And by their signs shown forth of old;
+
+    The Father's witness hath ordained
+
+    That we should hear with faith unfeigned.
+
+
+    Jesu, to thee our praise we pay,
+
+    To little ones revealed today,
+
+    With Father and blest Spirit One
+
+    Until the ages' course is done. Amen.
