The 1-nocturn ferial branch was rendering a V./R. versicle stuck
mid-list, as if marking a nocturn boundary that doesn't exist in a
single continuous nocturn. Live-verified against the reference engine
(Pofficium.pl, Monastic Tridentinum 1617) for Wednesday and Thursday:
the real office runs straight from the last psalm to the Capitulum,
with no versicle anywhere in the psalmody. The embedded mid-list V./R.
line in the source Psalmi matutinum.txt is inert there and was never
actually emitted by the engine — matins-ferial-antiphons.yml's
versicle field was a documented-but-unverified assumption, not real
content.

Replaced the multi-day cascading queue with the actual intended design:
only candidates at or above duplex-majus are worth carrying out of the
Palm-Sunday-through-Low-Sunday span at all - below that, a candidate
simply lapses for the year. Of those that clear the floor, the Nth day
after Low Sunday celebrates the Nth one (native-date order), winning
outright with no rank fight, demoting whatever's natively there to a
commemoration - one per day, positional, not a free-day search.
Caught a real bug while re-verifying: the ordinary single-hop transfer
check was independently leaking Low Sunday's own signal into the next
day, letting a below-floor candidate bypass the new gate. Fixed by
excluding the whole span from that path.
Inventoried the only duplex-majus+ candidates that can ever fall in the
reachable window (St. Benedict, St. Gabriel the Archangel, the
Annunciation, St. Mark, Ss. Philip & James), then bumped St. Patrick's
own rank to duplex-majus by direct instruction, adding him as the 6th.

The Easter octave cascade built last commit reused the existing
"duplex-majus+ still gets a bare commemoration" branch unchanged,
trusting its own citation (St. Mark within the Easter Octave). That
citation was a misreading. Live-verified: the Annunciation (Duplex I.
classis) transfers with zero commemoration on Holy Thursday itself, and
Chair of St. Peter at Antioch does the same on Ash Wednesday - the
exception was wrong everywhere this category is used, not just Holy
Week. privileged-feria-major now matches privileged-sunday exactly:
unconditional transfer, no exceptions, any rank.

Closes the tabled "Easter's own octave" mechanism gap. resolveDay only
ever checked yesterday/tomorrow for an inbound transfer - a single hop -
so anything impeded in Holy Week just vanished rather than reappearing
after the Octave. Live-verified the real behavior first (2033 proof
year): a candidate skips the whole privileged span and keeps walking
forward, FIFO by native date, until it lands; a transferred-in candidate
never gets the "still gets a nod" commemoration a native occurrence of
the same rank would along the way (confirmed with the Annunciation, zero
commemoration anywhere in the span). Also fixed Low Sunday itself, which
needed the same privileged-sunday treatment as Easter Day.
Built resolveForwardTransferLanding: a bounded queue simulation that
reuses applyIncomingTransfer unchanged per hop - its existing
privileged-feria-major no-op was already the right single-hop refusal,
it just needed a real cascade around it instead of a dead end.

Following the Ascensiontide fix, swept every remaining unverified Sunday/
feria precedence tier against the live reference engine:
- commemorations.ts's privileged-sunday rule was itself wrong: a
duplex-majus+ candidate was given a bare commemoration instead of
transferring, never actually verified. Live-checked the Immaculate
Conception (transfers off Advent II) and the Annunciation (transfers
off Palm/Easter Sunday) - confirmed correct by direct instruction.
privileged-sunday now transfers every rank unconditionally.
- eastertide's own Sunday tier was backwards (privileged-sunday instead
of ordinary-sunday) for the ordinary Sundays after Easter - live-
verified twice (Finding of the Holy Cross, St. Mark both win outright).
Easter Day itself still needs the stronger tier, now special-cased
directly since Sundays never consult the offset table.
Six existing tests updated to reflect real, live-verified behavior - each
had the old wrong "commemorated in place" assumption baked into its
expected value. Remaining unverified entries (Vigil of Pentecost/
Christmas, Corpus Christi/Sacred Heart) documented as such rather than
silently assumed correct.

The Sunday within the Octave of Ascension was letting a Duplex saint win

Every cross-psalm pair previously shared one antiphon under just the
first psalm, which read inconsistently once psalter-distribution.yml's
reslice left some pairs intact and split others. Each pair is now two
single-psalm groups: the psalm whose own words the shared antiphon
actually quoted keeps it, and its former partner gets a real antiphon
borrowed from elsewhere in the reference corpus where one exists, else
one composed fresh from its own opening verse.
The rest-of-year temporal nocturn-readings sweep was testing the Monday
after each named Sunday, relying on the now-removed leak to prove content
reachability for dates with no separately-authored ferial content -
repointed to the actual Sunday date. Updated the 2026-08-24 suppression

keepsOwnSecondVespers used a fixed duplex-2-classis floor on today's rank

tomorrow could still steal First Vespers from a higher-ranked-but-below-the-

Giles on 2026-08-31). The real "De Concurrentia Officii" rubric compares the
two days' ranks directly, with ties going to tomorrow — replace the floor
with that comparison when both sides have a real sanctoral winner, keeping

getDayLabel now surfaces the transfer signal added in the previous
commit: a transferred-in winner gets "(Rank, transferred)" instead of
just "(Rank)"; a transferred-in commemoration gets "(transferred)"
appended to its bare name; and the date a saint transferred away from
gets a trailing "St. X (transferred away)" note so a reader isn't left
wondering why an expected saint is missing that day. Deliberately worded
differently on the two sides (plain "transferred" reads as "arrived via
transfer" next to a rank parenthetical; "transferred away" spells out the
direction on the origin date, where there's no rank alongside it to
anchor that reading) and deliberately omits a landing date on the away
note, per direct instruction, since a real landing can chain further than
the single adjacent day resolveDay actually checks (an unmodeled case,
e.g. a transfer running into Holy Week).

Adds transferredFrom to both DayWinner's sanctoral variant and
Commemoration's sanctoral variant, set in calendar/index.ts's
applyIncomingTransfer whenever a transferred-in candidate actually lands
(wins outright) or ends up merely commemorated (lost a collision, or fell
below the landing day's own threshold) — previously this signal was
discarded after resolveDay used it once to decide the winner, so nothing
downstream could tell a transferred feast apart from a native one.
Also adds transferredAway to LiturgicalDay, set from a date's own native
occurrence when its candidate couldn't be kept there at all, so a UI can
note "this office moved elsewhere" without asserting a specific landing
date (which a later, unmodeled multi-hop chain — e.g. into Holy Week —

Corrected an earlier "no source exists" claim by live-querying real
commemorated instances of the Vigils of St. Lawrence and the Assumption
across six different weekdays. Their source files' own [Rule] block
("Versum Feria") turns out to be a real, sourced mechanism, not an
absence: a mere commemoration doesn't reuse the vigil's own antiphon at
all -- it borrows the plain ferial day's antiphon/versicle instead, and
that antiphon quotes the Benedictus canticle in weekday sequence (same
shape vespers-magnificat-antiphons.yml already uses for the Magnificat).
The versicle is a single fixed text. Sunday has no entry: a Vigil
transfers off an ordinary Sunday rather than ever reaching a
commemoration there, confirmed live as well as already true in this
app's own precedence rules.
sanctoralCommemorationPart now takes weekday and resolves this
dynamically for common-of-a-vigil saints, rather than needing a static
per-saint file. All 218 saints with an authored collect now have a real
commemoration antiphon.

Follow-up to the earlier bulk pass. Sourced the remaining category
templates: BVM feasts (13, reused the already-verified BVM suffrage
versicle plus each feast's own antiphon), angels (4, versicle inferred
from a saint file's own "structural category" note), Confessor-Doctor/
-Pope (7, resolved to C4a/C5a/C4b -- each inheriting its base category's
Ant2/Versum2 unchanged, no new content needed), several confessors and
apostles-plural (2, reusing already-sourced category versicles), and 5
fully-proper feasts (All Saints x2, Finding of the Holy Cross, Most
Precious Blood, Transfiguration, Our Lady of Ransom) given their own
real Ant2/Versum2 straight from their Sancti files.
213 of ~218 real saints now covered. Only the 5 Vigils remain open --
no dedicated Commune template exists for that category in the reference

Found that 217 of 220 saints with an authored collect had no
${propers}-commemoration.yml bundle, so sanctoralCommemorationPart was
silently falling back to a bare collect with no antiphon whenever that
saint was merely commemorated rather than winning outright (user-reported
for St. Raymond Nonnatus and the Decollation of St. John the Baptist).
Bulk-fixed: reused each saint's own proper antiphon where authored, else
the standard de-Communi [Ant 2]/[Versum 2] for that saint's own Common
category. Confirmed via three already live-verified commemorations
(Ss. Felix and Adauctus, St. Clare, St. Sabina) that [Ant 2]/[Versum 2]
are the real tags used for a mere commemoration, not [Ant 1]/[Nocturn 2
Versum] as first assumed -- corrected St. Raymond Nonnatus's file
accordingly. 182 of ~218 real saints now covered; entries not
independently live-verified are marked draft. Remaining ~36 (BVM feasts,
angels, confessor-doctors/popes, vigils) tracked in TODO.md.

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.

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.

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.

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
cycle has no per-feast override and must stay on today's own place in
the rotation regardless of whose office governs the evening's propers.

When already viewing today, clicking Today now snaps the selected hour
to whatever hour would be default for the current wall-clock time
(same as a fresh visit to /vu); when viewing another date it still just
jumps to today while preserving the current hour, as before. The link's
href is built from the same todayTargetHour() decision as the click
handler, so right-click -> open in new tab lands on the same target
instead of following a stale href.

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.

Live-verified byte-identical psalms, antiphons, and versicles against
St. Maurus/St. Gall (Abbot), St. Francis of Assisi/St. Jerome
(Confessor-not-Bishop), and the Octave of Ss. Peter and Paul
(Apostles-plural) — genuine full redirects, not new content. Swaps the
matins.test.ts ferial-fallback proof off St. Anthony Abbot (no longer
unauthored) onto St. Monica (Widow, still unauthored).

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
General/All Saints (C9) turned out to be a mislabeled backlog item (C9 is
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.

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).

Last of the 12-saint individual-Proprio list this session. Live-verified
against Divinum Officium (Monastic Tridentinum 1617), 2025-11-13 (clean
year): own chapter (Isa 8:18, "Ecce ego et púeri mei") and own hymn
("Salvéte, cedri Líbani," same text both hours); responsory and versicle
byte-identical to Common-of-Several-Martyrs's own already-authored
content.
This closes the individual-saint Proprio pass: 10 real saints/feasts
imported, 2 flagged stubs (Ss. Alexander etc., Ss. Machabees) confirmed
to need no new content. Combined with the 10 Common categories and the
Guardian-Angels/Archangels fix earlier this session, resolveOfficeBundle
now has real, live-verified Lauds/Vespers content for every gap the
original audit found.

Live-verified against Divinum Officium (Monastic Tridentinum 1617),
2026-08-06 (fixed date). Fully proper feast: own chapter (Phil 3:20-21),
own distinct responsory/hymn/versicle at each hour ("Amor Jesu
dulcíssime" Lauds, "Quicúmque Christum quǽritis" Vespers), with real
Alleluias baked into the responsories.

Fully proper feast, live-verified against Divinum Officium (Monastic
Tridentinum 1617), 2027-05-03 for the Finding (its own 2026 date
collides with a privileged Sunday) and 2026-09-14 for the Exaltation.
Own chapter (Phil 2:5-7), own distinct responsory/hymn/versicle at each
hour -- Lauds hymn "Lustris sex qui jam peráctis," Vespers hymn "Vexílla
Regis pródeunt," both with real Alleluias baked into their own text
(confirmed permanent via the Vespers hymn's own "In hoc Pascháli gáudio"
line, not seasonal contamination).
Authored under two ids (finding-of-the-holy-cross and proper-to-the-
finding-of-the-holy-cross): Exaltation's own saint file sets common:
proper-to-the-finding-of-the-holy-cross, a different id than its propers
field (a separate day-collect/antiphon lookup) -- without the second
copy, resolveOfficeBundle fell through to the ferial default for her.
