advent-4's own remaining Magnificat-antiphon gap turned out to be a
mechanism problem, not missing content: Dec 17-23 always carries one of
the seven "O Antiphons" at Vespers, keyed to the calendar date itself,
not to whichever Advent week (advent-3 or advent-4, varies by year)
happens to govern that date -- a single per-week file was structurally
the wrong shape.
Added vespers-o-antiphons.yml (MM-DD keyed) and a new lookup tier in
getMagnificatAntiphon, checked unconditionally ahead of both the
per-week temporal file and a real sanctoral winner's own antiphon --
direct instruction: the O Antiphon wins this one text slot on these
seven dates regardless of who otherwise wins the day (e.g. St. Thomas,
Dec 21, still keeps every other part of his own office). Two of the
seven (O Clavis David/O Oriens, Dec 20-21) couldn't be live-verified --
every reference-engine track routes those two dates through St.
Thomas's Vigil/feast instead, which this app's own vigil-of-st-thomas.yml
already documents diverging from -- so they're marked draft rather than
verified.

getVespersStatusLabel detected First-Vespers anticipation only via
winner.vespersFrom, a tag only ever set for a sanctoral tomorrow-winner
(tagVespersFrom). When Vespers anticipates a Sunday that wins its own
day outright (a temporal winner, e.g. 2026-08-29 anticipating 2026-08-30
since the Decollation of St. John Baptist is below the duplex-2-classis
floor that would let it keep its own evening), the tag never gets set
and the status wrongly read "Second Vespers (of today)" even though the
whole page was showing tomorrow's identity.
Comparing the resolved day's date against the originally-requested date
detects anticipation uniformly regardless of winner kind, so this drops
the vespersFrom dependency entirely.

The anchor-day and plain-temporal-fallback branches were listing any
commemorated saint before the winning identity, so a lower-ranked saint
merely riding along as a commemoration (e.g. St. Andrew on Advent I, or
Ss. Tryphon/Respicius/Nympha on an ordinary Sunday) read as if it were
the day's own winner, with the actual winner's rank label dangling at
the end with no name attached. The winner should always lead.

canticleText() always returned the whole canticle's stored citation
("Deut 32:1-65"), even when only slicing out half its verses -- both
Saturday Lauds pieces showed the same full range regardless of which
half was actually being said. Derive the citation from the slice's own
first/last verse numbers instead, only when slicing; a full canticle's
stored citation is left as-is, since it already matches what's shown
and a formula can't reproduce an irregular one like
canticum-trium-puerorum's "Dan 3:57-88,56" (a non-contiguous liturgical
splice).

Confirms 2026-08-29 Lauds and 2026-08-28 First Vespers both keep the
ferial psalm numbers (Duplex, below duplex-majus) while still layering
on the feast's own proper antiphons -- and that an override group with
no matching ferial slot (Puellae saltanti / Arguebat) is dropped, not

nativity-of-st-john-the-baptist.yml's `common` field (common-of-an-apostle)
was the same mistaken placeholder as the Beheading's, but this feast
needed a different fix: the reference engine assigns it no Commune at
all -- every [Rule] line in Sancti/06-24.txt and SanctiM/06-24.txt points
to proper text, never a Commune category -- so there's no better-fitting
id to swap in either.
Authored the real proper content that was still falling through to the
apostle Common, live-verified against the local Divinum Officium CGI
instance (Monastic Tridentinum 1617):
- Matins invitatory antiphon ("Regem Præcursóris Dóminum")
- Matins hymn ("Antra desérti téneris," with the Monastic doxology
substitution already used by this feast's own Lauds/Vespers hymns)
- Full Matins Nocturn 1-3 psalmody + nocturn versicles (Nocturn 1/2 reuse
St. Lawrence's own shared psalm-number pool per "Psalmi Dominica";
Nocturn 3 reuses St. Lawrence's own canticle scripture files verbatim,
since the citations are identical)
- Vespers psalmody (only 4 psalm slots at this Monastic rank, not 5 as a
naive reading of the raw Ant Vespera list would suggest)
- Nocturn 2/3 responsories on the existing nocturn-readings file
`common: common-of-an-apostle` is left in place as a fully inert
placeholder (a non-optional field with no better id available) with an
updated comment explaining why.

decollation-of-st-john-baptist.yml's `common` field was set to
common-of-an-apostle -- a mistaken placeholder (he isn't an apostle) that
leaked into the Aug 29 Matins invitatory and the Lauds/Vespers office
bundle. Corrected to common-of-a-martyr, matching the file's own already-
correct `minorHoursCommon` field.
Also corrected a stale comment in the feast's own nocturn-readings file
claiming neither Nocturn 2 nor 3 has a proper responsory: Nocturn 2's own
closing responsory is genuine proper text (not a Commune reference like
Nocturn 3's), and is now authored.

compline-preces.yml was already the secular Tridentine 1906/1910 text
word-for-word (verified live against both tracks), so no text change
was needed there. The actual gap: both Monastic and secular tracks drop
Compline's Preces to nothing on a Double-or-higher, unlike Vespers/Lauds
which fall back to a short form. Per explicit request, this is now a
deliberate vu-specific deviation from both tracks: on a Double, Compline
substitutes the same short Kyrie/Pater-Noster litany Vespers already
falls back to on Sundays/feasts, instead of showing nothing.

Covers common-of-an-angel (both hours, via Guardian Angels' First
Vespers/own day), common-of-a-dedication (Vespers, via its own day),
and the common-of-an-evangelist/several-women-martyrs aliases (one
date-based test via St. Mark where a real date is reachable, direct
unit tests where every carrier saint is below this override's rank
threshold or shadowed by an existing per-feast override).
Two pre-existing Vespers test dates had to move again for the same
reason as the previous session's fix: newly-correct category coverage
retroactively changed what a "clean ferial"/"own kept evening" date
actually resolves to. 2026-09-28 (anticipates St. Michael's own First
Vespers) moved to 2026-10-12; Guardian Angels' own day (Oct 2) moved to
Oct 1 (her First Vespers) once tracing resolveEveningDay showed she
doesn't keep her own Second Vespers there.

Vespers psalms on Mon-Sat were silently following the anticipated
First-Vespers day's weekday instead of the actual calendar date's, since
resolvePsalmody reused resolveEveningDay's result (correct for
propers/office, which legitimately borrow tomorrow's identity, but wrong
for the ferial psalm cycle, which has no per-feast override of its own).
Also adds a duplex-majus+ Common-category psalmody override to both
Lauds and Vespers, mirroring Matins' existing saint/category mechanism.
Lauds already had a per-feast-only override; Vespers had none. 8 of 24
Common categories authored for both hours, live-verified against the

Replaces the lesson+isGospel flag with a dedicated 'gospel' ResolvedPart
carrying an optional nested homily. Previously a Gospel pericope and its
patristic homily were two separate pool entries, which the front-light
1/1/rest nocturn slicer could split into different nocturns purely by
index. buildReadingPool now folds an isGospel:true reading and its
immediately-following same-nocturn homily into a single pool entry, so
the pairing is structural rather than a convention the slicer has to
honor. hour-view.ts renders the pair as one visually grouped section.

When tonight anticipates tomorrow's First Vespers, resolvePsalmody was
keying off the borrowed day's weekday instead of today's actual calendar
weekday, silently shifting the fixed 6-day psalm rotation. The psalm

the rotation regardless of whose office governs the evening's propers.

jumps to today while preserving the current hour, as before. The link's

This Duplex I classis feast (instituted by Pius IX, 1847) didn't exist
anywhere in vu's calendar. Dated per the older, pre-1955 reckoning --
Wednesday after the 2nd Sunday after Easter (Easter+17) -- rather than the
1913 Pius X reform's later placement on the 3rd Sunday after Easter
itself, per direct instruction. Mechanism: one new temporal-feast record
plus a new EASTER_OFFSET_STARTS table entry (the only code change --
everything else is the existing generic anchor-driven resolution).
Authored the feast day's own Matins reading and its full 7-day octave
(days 2/3/4/6/7/8; day 5, the Sunday, has no override in the source at
all, correctly left unauthored).
Fixed one real collateral effect: an existing fixed-year calendar test
(St. Pudentiana vs. St. Peter Celestine, 2038-05-19) broke because that
date now falls on this octave's own closing day, tying Celestine's rank
against the octave's threshold -- the app's own documented tie-break
correctly favors the octave that year. Moved the proof date to 2033.
Also bumped the PWA precache file-size cap (6 MiB -> 8 MiB) since this
content pull pushed the main bundle past the previous limit.

lauds-capitulum-st-gabriel-archangel.yml carried Apparition of St.
Michael's own capitulum ("Significávit Deus...") under Gabriel's id --
found in passing while authoring his Matins psalmody. His real
capitulum, read directly from the reference engine's Sancti/03-24.txt
([Capitulum Laudes]), is Daniel's own account of the angel's visitation
(Dan 9:21-22), genuinely proper to Gabriel, not shared with Apparition
despite sharing the same hymn. No separate vespers-capitulum file exists
for this id, so the fix covers both hours via vespersCapitulumForOverride.
Updated tests/hours/lauds.test.ts: removed Gabriel from the shared-
chapter assertion loop (Guardian Angels/Raphael still legitimately share
Apparition's chapter, confirmed via their own saint files' explicit
source cross-references) and added a dedicated test for his own chapter.

resolveMatinsInvitatoryText's Common-category tier existed but only had
Common-of-an-Apostle authored, so every other Common category fell all
the way through to the plain ferial invitatory antiphon regardless of
rank (e.g. St. Joseph Calasanctius, 2026-08-27, Confessor). Adds the
Confessor family (5 duplicated ids, matching the hymn's own precedent),
Martyr family (2 ids + Several Martyrs), Virgin family (2 ids), and
Dedication — all read directly from the reference engine's own
Commune/C-number [Invit] lines. Holy Women (C7) needs a name-template
mechanism this project doesn't have yet for invitatory antiphons, and

actually the Office of the Dead) — both logged in TODO.md instead.

Nocturn count stays rank-based (readings only), but psalm content for an
exactly-Duplex sanctoral winner with no proper now always uses that
weekday's real ferial psalms instead of Common's own psalm numbers (or a
bare mechanical chunk) — so the psalter actually gets prayed rather than
repeating the same dozen Common psalms. Each nocturn's antiphon comes from
the saint's own minorHoursCommon Terce/Sext/None text (real, distinct per
nocturn, already proven non-psalm-specific), with Common's own Matins
versicle per nocturn; falls back to bare only where that content isn't
authored. Duplex-majus+ winners are unaffected.

Adds pre-1955 TemporalFeastRecords (rank duplex-1-classis, real octaves)
for the three "feasts of the Lord" that were previously only referenced
as bare date offsets: Corpus Christi/Sacred Heart's own days already
couldn't lose to a sanctoral candidate, but with no record the day fell
back to the generic Trinity-week feria collect and never displayed its
real name; Ascension had no protection at all against an ordinary saint
winning it outright. Sacred Heart's own record carries the
forbidsSuccessorCommemoration flag added in the prior commit, refusing to
commemorate Most Precious Blood on the rare late-Easter date they fall
adjacent.
octave.wins is set to duplex on all three, matching Pentecost's own
verified threshold, despite a known conflict with a previously
live-verified case (St. Ubald winning First Vespers within Ascension's
own octave) -- kept per direct instruction; the affected tests (Ubald,
St. Margaret of Scotland) were updated to assert the new behavior, and
the tradeoff is documented in ascension.yml and TODO.md. A handful of
unrelated test fixtures that happened to land inside these new octave
windows were moved to nearby clean dates.

Finished the "ferial/other" audit bucket via each saint's own source
file. Vigils (9 saints) are not a gap at all: every vigil's own [Rule]
explicitly says "Responsory Feria"/"Versum Feria" -- deliberate rubric,
matching this app's existing isFerialOrVigil convention. Even the "ex
C1v" tag on the 6 apostle vigils resolves to the same plain ferial text
when live-queried, confirming no override applies to the Lauds/Vespers
bundle for any vigil.
Common-of-the-BVM (5 feasts) is a real category: each source file says
plain "ex C11"/"vide C11". Live-verified votive=C11: chapter Sir 24:14,
Lauds hymn "O gloriósa Dómina" (the same pre-Urban-VIII text as the
Annunciation's own separate proper), Vespers hymn "Ave maris stella,"
same responsory at both hours, distinct versicles per hour.
Surfaced one masked collision: the Annunciation now resolves through
this Common instead of the ferial default (real improvement, still
interim until its own proper content is imported). Moved the
Passiontide-seasonal-office Vespers test off its date (Mar 25) onto the
clean Mar 30.

Read straight from the source (Sancti/02-12.txt, Ss. Seven Holy Founders
of the Servite Order -- the only saint in this category): its own [Rule]
says plain "vide C5," no votive number of its own. Duplicated the same 7
files under common-of-several-confessors.
This closes every Common category this session's audit found with real
users -- resolveOfficeBundle now has real Lauds/Vespers content for
every category, not just the two it started with.

Methodology upgrade this session: read each saint's own Sancti/MM-DD.txt
[Rank]/[Rule] field directly instead of hunting for a per-saint clean
year to live-query -- it states the real Common assignment (or a direct
proper-content inheritance) with zero calendar dependency.
Guardian Angels/St. Gabriel/St. Raphael the Archangels' own files say
"vide C4," but that's a Missal/Mass-propers designation -- their real
Monastic-breviary file (SanctiM/10-02.txt) cross-references St. Michael's
Apparition (Sancti/05-08, already fully authored in this app) directly
for the chapter/responsory at every hour. No common-of-an-angel category
exists in the source at all. Duplicated St. Michael's Apparition's 7
Lauds/Vespers files under each of the three saints' own ids (proper
content, not a Common fallback), live-verified on their own real 2026
days.

Both genuinely distinct from Virgin(-Martyr) -- different chapter
Prov 31:10-11 "Mulíerem fortem," different hymn "Fortem viríli péctore"
-- but share that category's exact responsory pattern and versicle
byte-for-byte in both hours. Live-verified via St. Anne's own real day
(Jul 26). St. Monica's real day (May 4) confirms common-of-a-widow
shares the identical content with common-of-a-holy-woman, so the same 7
files were duplicated under that id too -- first content authored for
either category at all.
Proof: St. Anne's and St. Monica's own days for Lauds, St. Margaret of
Scotland's real First-Vespers anticipation (Jun 9 -> 10) for Vespers.

common-of-a-confessor-doctor (4 saints) is another "same content,
different id" case: live-verified votive=C4a byte-identical to plain
votive=C4 (Common-of-a-Confessor-Bishop), so duplicated verbatim rather
than authored fresh, matching the already-existing matins-hymn-common-
of-a-confessor-doctor.yml precedent.
common-of-an-apostle (3 saints/feasts) is genuinely distinct: chapter
Eph 2:19-20, hymn "Exsúltet cælum láudibus" (byte-identical Lauds/
Vespers), shared versicle "Annuntiavérunt ópera Dei." Also duplicated
under the separate common-of-apostles (plural) id used by the Octave of
Ss. Peter and Paul.
Proofs: St. John Damascene (own day) + St. Robert Bellarmine (First
Vespers) for Confessor-Doctor; Commemoration of St. Paul (own day) + the
Beheading of St. John the Baptist (First Vespers) for Apostle.

Live-verified against Divinum Officium (Monastic Tridentinum 1617)
votive=C6: chapter 2 Cor 10:17-18, hymn "Jesu, coróna Vírginum" (byte-
identical Lauds/Vespers), shared versicle "Diffúsa est grátia in lábiis
tuis" -- only the two responsories differ between the hours. Cross-
checked plain common-of-a-virgin (St. Praxedes) renders the same real
content, matching the already-existing benedictus-antiphon-common-of-a-
virgin.yml precedent -- duplicated the same 7 files under that id too.
Proof: St. Apollonia's own clean year (2029-02-09, her 2026 date collides
with St. John of Matha) for Lauds, St. Praxedes's real First-Vespers
anticipation for Vespers.

Same finding as common-of-a-confessor: live-verified (St. Maurus, Jan 15;
St. Odo, Feb 7) that Common-of-an-Abbot's real Lauds/Vespers content is
identical to Common-of-a-Confessor-Not-Bishop's -- an Abbot isn't
necessarily a bishop, so the traditional rite reuses the plain Confessor
common for them. Duplicated the same 7 files under this id, matching the
existing benedictus-antiphon-common-of-an-abbot.yml precedent. Proof
tests on St. Maurus (Duplex II. classis, own Lauds + real First-Vespers
anticipation Jan 14 -> 15).

Fixed a real audit-methodology bug first: the bulk gap-audit was sampling
each saint's own date via prayVespera, which reflects whatever saint
claims First Vespers that evening (often a neighboring day's), not the
sampled saint's own category. Redid it via prayLaudes (no anticipation).
That surfaced the real finding: common-of-a-confessor (37 saints, this
app's largest remaining gap) isn't a distinct liturgical Common -- it's
common-of-a-confessor-not-bishop under a different label. St. Joseph's
and St. Thomas Aquinas's chapter is byte-identical to the already-
authored Sir 31:8-9 text, and several of the 37 saints' own file comments
already say "vide C5" (Confessor Not a Bishop) directly. Not relabeled
across the 37 saint files, since matins-hymn-common-of-a-confessor.yml
and benedictus-antiphon-common-of-a-confessor.yml already establish this
plain id as the real, working one for those saints' Matins/Benedictus
content -- duplicated the Lauds/Vespers bundle under this id too, to
match that existing convention.
Updates two existing tests whose dates collided with this fix: the
FERIAL_MONDAY constant (moved off St. Raymond Nonnatus's own day) and a
new Vespers proof on St. Joseph's First Vespers.

Third Common category (17 real users) with no Lauds/Vespers bundle
authored. Live-verified against Divinum Officium (Monastic Tridentinum
1617) votive=C4: chapter Sir 44:16-17 "Ecce sacérdos magnus," Lauds hymn
"Jesu Redémptor ómnium," shared versicle "Justum dedúxit Dóminus per vias
rectas." Found the Vespers hymn is byte-identical to Common-of-a-
Confessor-Not-Bishop's own ("Iste Conféssor Dómini sacrátus") even though
the chapter, both responsories, and the Lauds hymn all genuinely differ
between the two categories -- reused that already-authored text verbatim
rather than re-deriving it.
No real Duplex-II-classis+ saint exists in this category, so the Vespers
proof uses St. Ubald's real First-Vespers anticipation instead of a
votive-only proof. Updates one existing test (2026-04-20, Paschaltide
seasonal office) whose date turned out to also anticipate St. Anselm's
First Vespers, previously masked by this same gap.

Next-largest remaining Common category (22 real users) with no Lauds/
Vespers bundle authored, same fix pattern as Confessor-Not-Bishop and
Martyr(-Bishop). Live-verified against Divinum Officium (Monastic
Tridentinum 1617) votive=C3: chapter Sap 3:1-3, Lauds hymn "Rex glorióse
Mártyrum," Vespers hymn "Sanctórum méritis ínclyta gáudia," shared
versicle "Exsultábunt Sancti in glória." Cross-checked votive=C3/C3a/C3b
byte-identical, confirming the Missal-collect split (plain-martyrs vs.
Pope-martyrs) doesn't carry through to this Office bundle. Proof tested
on Ss. Placid and Companions (Duplex II. classis, real un-outranked
Second Vespers).

St. Zephyrinus (Aug 26, common-of-a-martyr-bishop, Simplex) claims First
Vespers over St. Louis's Aug 25, but that evening was showing the plain
ferial hymn instead of a real Common-of-a-Martyr hymn: no content had
been authored yet for this Common category's Lauds/Vespers bundle, so
resolveOfficeBundle's chapter lookup came back missing and the whole
bundle fell through to the ferial default.
Live-verified against Divinum Officium (Monastic Tridentinum 1617)
votive=C2b: chapter Jac 1:12, Lauds hymn "Martyr Dei, qui unicum," Vespers
hymn "Deus tuorum militum," shared versicle "Justus ut palma florebit."
Used the votive-office view rather than a real saint's own day for the
same structural reason as the earlier Confessor-Not-Bishop fix: every
real Common-of-a-Martyr-Bishop saint either has proper content of his own
(St. Lawrence, St. Stephen) or never reaches the rank needed to keep his
own Vespers (St. Zephyrinus, St. Callistus). Cross-checked votive=C2/C2a/
C2b/C2-1 all render identical text, so the same 7 files were duplicated
under the plain common-of-a-martyr id too (St. Hadrian, St. Hermes, St.
Fidelis of Sigmaringen).
Updates one existing Vespers test whose date (2026-03-03) turned out to
also anticipate St. Lucius I's First Vespers, previously masked by this
same content gap; adds two new proof tests and a TODO.md entry.

day-nav.ts's header always resolved via resolveDay(date) regardless of
selected hour, so viewing Vespers/Compline on a day whose evening
anticipates tomorrow's First Vespers (e.g. Aug 25, 2026: St. Louis's day,
but St. Zephyrinus claims First Vespers per calendar/vespers.ts) still
showed today's saint in the header while the hour's actual content had
already switched to tomorrow's. Now uses resolveEveningDay for those two
hours specifically.
Also adds an explicit "First Vespers (of tomorrow)" / "Second Vespers (of
today)" status line to the Vespers header, via new
getVespersStatusLabel(), so the anticipation/commemoration result is
visible rather than only inferable from which saint's name shows up.

Real Monastic 1617 has no Preces at the Little Hours, and that was
previously documented as intentional. Per this project's "not a
reconstruction" design, Prime was recently given Preces in the secular
Tridentine form as a deliberate deviation from Monastic — do the same
here: the reference engine's ferial minor-hour Preces (Kyrie, Pater
Noster, then "Domine Deus virtutum, converte nos..." V/R pairs) is
authored as a single shared common id and wired into all three hours
after the chapter. By explicit choice this is said every day regardless
of rank, mirroring Prime's own "every ferial day" simplification, rather
than importing the reference engine's Sunday/feast form, whose sourcing
(a V/R block reused from Compline) looks like a data quirk rather than
genuine minor-hour content.

isSundayOrFeastOffice treats any sanctoral winner, Vigils included, as a
"feast," so a Vigil day was getting the Sunday/feast Preces. Add a
by-day-kind 'vigilIsFerial' flag, set only on Prime's Preces part (its
capitulum keeps the old behavior), so a Vigil-ranked winner now routes
to the ferial Preces text instead.

Monastic Prime's own Dominicales Preces drop the "Et ego ad te, Domine,
clamavi..." versicle block and shorten the closing "Miserere nostri,
Domine... Fiat misericordia tua..." set. Prefer the secular Tridentine
form instead (live-verified against Divinum Officium's "Tridentine -
1906" version), keeping "beato Patri nostro Benedicto" in the Confiteor
by explicit choice even though the real secular Confiteor omits it.
The Sunday/ferial by-day-kind split stays as-is; the ferial form
(prime-preces-feriales.yml) is unchanged and continues to show on every
ferial day by deliberate choice, more generously than the historical
rubric.

Live-verified against Ss. Fabian and Sebastian's clean date (2029-01-20,
Monastic Tridentinum 1617). Genuinely distinct psalm scheme from
common-of-a-martyr (single martyr), not a duplicate. Adds Wisdom 3:1-6
to the scripture store for Nocturn 3's canticles. Swaps the matins.test.ts
ferial-fallback proof to St. Anthony Abbot now that Fabian/Sebastian
resolve through this new category instead.

resolveMatinsHymn gained a Common-category tier (override -> octave ->
Common category -> season -> ferial), reusing matins-psalmody-
overrides.ts's own getSaintRecord(id)?.common lookup pattern. The
invitatory antiphon (invitatoryParts), previously one hardcoded fixed
text for every day of the year with only full-vs-incipit doubling
varying by rank, now goes through a real resolveMatinsInvitatoryText
(override -> Common category -> season -> ferial, no octave tier) before
the doubling step.
Content authored this pass: Common-of-an-Apostle only, both hymn
(matins-hymn-common-of-an-apostle.yml, "Aeterna Christi munera") and
invitatory antiphon (matins-invitatory-common-of-an-apostle.yml, "Regem
Apostolorum Dominum"), both read directly from the reference engine's
Commune/C1.txt. Live-verified: St. Bartholomew (2026-08-24) and St.
Andrew (2026-11-30) both now resolve to this Common's text.

nocturnReadingIds unconditionally pooled the plain temporal-cycle and
month-week reading ids into every day's nocturn-reading pool, even when
a real feast wins the day outright with zero commemorations
(decideOccurrence's `ordinary-feria` branch, which correctly suppresses
the temporal identity entirely). St. Bartholomew (duplex-2-classis,
2026-08-24, a Monday) has no Nocturn 3 content of his own, so the
leftover 13th-Sunday-after-Pentecost and month-week readings wrongly
filled his Nocturn 3.
Gate the pooling on whether the day's own occurrence decision actually
retained the temporal identity (day.winner.kind === 'temporal', or a
`temporal`-kind entry in day.commemorations) — mirrors getDayCollects's
existing pattern for the same question.

Matins now sings "Te decet laus" (Psalterium/Common/Prayers.txt's [Te
decet]) immediately after the Te Deum on every 3-nocturn day, matching
Rule of Benedict ch. 11's close of Vigils. New common text
te-decet-laus.yml, wired into both matins.ts branches that render a Te
Deum; absent on ferial days along with it.
Also drops Psalm 129 (De profundis) from the Lauds ferial Preces and
Psalm 50 (Miserere) from the Vespers ferial Preces, per direct
instruction — both were embedded inline in the live-transcribed text.
Updated the affected fixture tests to key off a versicle that survives
the removal instead of the now-absent psalm text.
