- nocturnReadingIds no longer lets a demoted commemoration's temporal id
(equal to the plain governing-Sunday temporalId) sneak a Sunday's own
homily into an unrelated weekday's pool via the commemorations loop —
a second code path than the one a prior fix gated, affecting 18
days/year.
- Reading pool order now follows id priority (winner first, then every
temporal commemoration, then every sanctoral commemoration) instead of
raw nocturn-tag/array order, matching the day label's own
temporal-then-sanctoral convention.
- gospelReadingPart now falls back to the paired homily's own responsory
when the Gospel entry has none of its own, instead of silently
dropping it.
- Patristic source labels now show "(for <occasion>)" so a reader can
tell which occasion a pooled reading belongs to on a multi-reading day.
- collectCommemorations no longer restates the plain generic temporal
label (e.g. "Saturday in the 15th week after Trinity") once anything
else is already being celebrated — general, not Ember-specific.
Updated 4 day-label tests that encoded the old behavior.

Trinity Sunday wasn't modeled at all: getDayLabel had a purely
cosmetic "Trinity Sunday" label overlay for the Sunday after
Pentecost, but resolveTemporalId just fell back to post-pentecost-01
(ordinary-sunday category), so any Duplex+ saint assigned that date
(e.g. the Queenship of the BVM, fixed May 31) won outright, real
Trinity Sunday content never appearing anywhere.
Added a real temporal-feasts/trinity-sunday.yml record (Easter+56,
Duplex II. classis, live-verified). Per direct instruction,
unconditional: true (same shape as christ-the-king.yml) -- a
principal Sunday shouldn't lose a same-rank fixed-date collision, and
the one real collision case (Queenship of the BVM) isn't
independently verifiable against Monastic 1617 at all (that calendar
doesn't carry the Queenship feast -- May 31 there is St. Petronilla
instead).
Authored the full office and registered trinity-sunday in
ALWAYS_OVERRIDE_TEMPORAL_IDS -- the same generic mechanism already
built for the Pentecost-cluster fix, no new code needed: collect,
Benedictus/Magnificat antiphons, Matins hymn ("Summæ Deus cleméntiæ"),
Lauds/Vespers chapter (shared, Rom 11:33) and hymn (shared, "O lux
beáta Trínitas", already the pre-Urban VIII text), each hour's own
distinct responsory/versicle -- all live-verified 2026-05-31.
Fixed 3 pre-existing tests written around the old cosmetic-label
behavior, two of which had never-verified guesses baked in as if
correct: day-label.test.ts's "names the anchor day itself" test and
its "outranks an active octave" test (was asserting "Duplex I Class",
a guess -- the real live-verified rank is Duplex II);
transfer.test.ts's St. Felix I test.

Same fix as ember-september-friday.yml (already done): each file's
Lectio1-3 turned out to be one continuous, unbroken homily (Bede,
Gregory, or Ambrose's Commentary on Luke for the two Advent cases,
cross-referenced from the Annunciation's own Common and confirmed
contiguous by reading the source file directly), split only to fill
the fixed 3-lesson slot count. Recombined ember-september-wednesday/
-saturday and ember-advent-wednesday/-friday/-saturday into single
readings, keeping each one's first lesson's own responsory.
All 6 Ember days now recombined -- no remaining split-for-no-reason
readings in this family. Updated ember-days.test.ts's lesson-count
table accordingly.

Lectio1-3 in ember-september-friday.yml were one continuous, unbroken

calendar/day-label.ts never surfaced an Ember day's own identity
anywhere: collectCommemorations only matched a temporal commemoration
against resolveTemporalId(day.date), never an Ember-relabeled id, and
the winning-outright fallback used the generic ordinal weekday label
with no id awareness at all. Adds a standalone emberDayLabel lookup,
deliberately kept out of temporal-feasts.ts since that table doubles
as isFerialOrVigil's bareness check and would have silently turned
off Ember days' own ferial Preces.

Live-verified (Monastic Tridentinum 1617) that an Ember day's Lauds
psalmody stays on the plain ferial default throughout -- only the
Benedictus antiphon (and, Wednesday/Friday only, the Magnificat
antiphon) is genuinely proper to the day. Adds the 6 Benedictus +
4 Magnificat antiphon files (Ember Saturday's Second Vespers is
always ceded to the following Sunday on both quarters, so no
Magnificat content exists to author there).

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

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.

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
the floor only as a fallback against a plain Sunday.

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 —
could get wrong).

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.

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.

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.

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.

(Simplex), but didn't. This was the exact untested asymmetry the old
commemorationOf's own doc comment flagged as "inferred by symmetry, not
independently live-verified." Live-verifying now shows the two
directions genuinely differ: a Simplex predecessor losing to tomorrow's
First Vespers is correctly excluded (Aug 7 Donatus case, "nihil de
præcedenti"), but a Simplex successor displaced because today keeps its
own Vespers IS still commemorated (Aug 24->25, "commemoratio de

Researched whether September/Advent Ember days belong in the
movable-feasts.ts table alongside Christ the King/Immaculate Heart of
Mary. Live-verified against the reference engine they don't: Ember days
are privileged ferias (a saint can still win outright against them), not
named feasts contesting the day by rank.
Two smaller pieces instead: calendar/temporal.ts's septemberEmberDayOffset
(Sunday nearest Sept 14, same "nearest" arithmetic adventStart already
used, factored into a shared nearestSunday helper) feeds a new
resolveTemporalCategory check giving those 3 dates privileged-feria-minor
(live-verified correct); calendar/ember-days.ts's applyEmberDay relabels
the day's own temporal id to the Ember day's own (so its real content is
found) when the feria itself wins, or adds a commemoration when a saint
does. Advent Ember days needed no precedence change -- Advent's own
season default already covers them.
Found and fixed a real bug along the way: matins.ts's nocturnReadingIds
only ever pulled a commemorated *sanctoral* id's own readings, never a
commemorated *temporal* one's -- so a commemorated Ember day (the common
case) would never have surfaced its own content. Same root cause as the
day.winner.id gap the IHM relocation fixed earlier, just hiding in the
commemorations loop instead.
Authored all 6 days' real collect + 3 Matins readings each, transcribed
directly from the reference engine (September: Tempora/093-{3,5,6}.txt;
Advent: Tempora/Adv3-{3,5,6}.txt, whose lessons are themselves a
cross-reference to the Annunciation's own Common, followed and
transcribed from there). Kept as 3 separate readings per day rather than
the usual combine-into-one default, since each carries its own
genuinely distinct proper responsory.

The bespoke applyImmaculateHeart function (following the applyMarianSaturday/
applyChristTheKing precedent of one hand-written override function per
feast) doesn't scale: several more feasts are planned that all reduce to
"weekday N days from Easter Sunday" (Ember/Rogation days, more
Sacred-Heart-family Marian devotions, St. Joseph's pre-1955 Eastertide
feast, Lenten Friday Passion devotions), and one-off functions invite
subtle ordering bugs -- applyImmaculateHeart had to be sequenced after
applyMarianSaturday specifically or it would have been silently clobbered.
Replaced with calendar/movable-feasts.ts's generic applyMovableFeasts,
which scans calendar/temporal-feasts.ts's existing per-feast YAML records
for a new optional `easterOffset` field. Adding the next movable feast is
now a new data/calendar/temporal-feasts/<id>.yml file with `rank` and
`easterOffset` set, not a new TypeScript function. Same rank-compared,
commemorate-the-loser semantics as before, just centralized instead of
duplicated per feast.
christ-the-king, marian-saturday, and christmas-octave-sunday stay as
their own functions -- they're structurally different rules (a fixed
month-position search, a date-less fallback default, and a fixed-date-
range Sunday search, respectively), not Easter offsets, so force-fitting
them into this table wouldn't actually simplify anything.
No behavior change -- the existing Immaculate Heart of Mary test suite
passes unchanged through the new generic path.

Saturday after the Feast of the Sacred Heart -- its real diocesan date
from 1914 until Pius XII's 1944 fixed-date decree, and also the date the

Required real new mechanism, not just a data move: a new bespoke
calendar/index.ts override (applyImmaculateHeart, following the existing
applyMarianSaturday/applyChristTheKing precedent), a move from the
sanctoral saints store to the temporal-feasts store (different propers
lookup entirely), and a real bug fix in matins.ts's nocturnReadingIds,

Same `wins: duplex` override as the Assumption's and Pentecost's
octaves, applied to two more common-class octaves. Accepted side
effect: St. Damasus (Dec 11) and St. Nicholas of Tolentino (Sep 10),
both Semiduplex, no longer tie-and-win an ordinary octave day here --
they're now commemorated instead of winning outright.

Demote St. John Eudes (Aug 19) from Duplex to Semiduplex -- too minor
a confessor to keep outranking the Assumption's octave. To make that
demotion actually cede the day, raise the Assumption's octave to
`wins: duplex` (same pattern already used by Pentecost's octave), so an
ordinary-day tie no longer automatically favors the occurring saint.
Promote St. Thomas of Canterbury (Dec 29) to Duplex so he keeps
winning against the Christmas octave stack now that ordinary-day ties
are no longer a given.
Also add a closing-day tie-break to octave-vs-octave precedence
(pickWinningOctave): when two active octaves tie in rank, the one on
its own closing day now wins the label contest, ahead of the existing
"more recently started" tie-break. Needed because Assumption's day 3
and St. Lawrence's own closing day (Aug 17) now tie at Duplex, and the
closing day should still govern that date's label.

Keeps Simplex commemorating in place, but a Semiduplex feast on an
ordinary Sunday goes back to transferring off to the next open day —
this app's own design choice, not a correction against a reference
engine. The transfer mechanism is already generic: this file's `decideOccurrence`
only signals "couldn't hold onto this candidate" for the day itself;
calendar/index.ts's resolveDay is what independently checks each
neighboring day's own native occurrence for an incoming transfer and
claims it — no separate lookback logic needed.

Semiduplex (or lower) saint off the Sunday instead of commemorating it
in place — an earlier, unverified guess. Live-verified against both
Tridentine 1906 and Divino Afflatu 1954 (St. Gregory Thaumaturgus, St.
Clement, St. Apollinaris, St. Thomas Becket, all real cases): the saint
stays and is commemorated on the Sunday itself, same as Simplex, never
pushed to the next open day. This is what was actually moving Gregory
onto Nov 18 — not a data error. `applyChristmasOctaveSunday`'s own
Dec 26-29 special case needed a matching adjustment (per its own
documented intent, the displaced saint there is deliberately *not*
commemorated in place, since he reappears in full on Dec 30 instead).
- getDayLabel had five branches, each hand-assembling its own
filter/format logic for which commemorations to show — which is why
the octave phrasing, the closing-day title, and a missing Sunday
commemoration turned into three separate bugs earlier instead of one.
Replaced with a single shared `collectCommemorations` used by every
branch. This also exposed that the sanctoral-winner branch never
showed any commemorated saint at all, and every other branch only
showed the *first* one (`.find()`), silently dropping real collisions
— both now show every commemorated saint, matching this app's own
generous-commemoration design.

Three related day-label bugs, all found via Aug 19's mislabeled Assumption
octave commemoration:
- A sanctoral winner that displaces the only active octave now shows the
octave's real "Nth Day within the Octave of X" phrasing (no rank, since
it's riding along under the winning feast), not a bare feast name.
- An octave's own closing day now titles itself "Octave of X", matching
the real DO's "in octava" vs. "infra octavam" distinction, instead of
"8th Day within the Octave of X".
- A sufficiently-ranked octave can now outrank a privileged temporal
season (e.g. the Immaculate Conception's octave outright winning several
of its days against Advent, live-verified against Divino Afflatu 1954),
via a new shared octaveGoverningPrivilegedDay helper used by both the
day label and the actual office-content resolver. Deliberately excludes
Christmastide, whose own stacked octaves are structurally already that
season's temporal content rather than a foreign add-on.
Updates a Matins test fixture that had unknowingly relied on the
Dec 15 bug (Advent ferial + a lone commemorated saint) and splits it into
a clean ferial case plus a dedicated commemorated-saint case.

Rank display (added in 1fc4bd7) only fired for a plain sanctoral
winner. Every other case -- an active octave day, a named temporal
feast, a season anchor day (Easter, Trinity Sunday, Epiphany), or the
plain ordinal Sunday/feria fallback -- showed no rank at all, which is
what made today's octave day (Aug 18, day 4 of the Assumption's
octave) show no rank. Octave days use the octave's own already-computed
effective rank; anchor days get a fixed Duplex I Class (Ash Wednesday
excepted -- a privileged feria has no duplex-scale rank); the plain
fallback derives a Semiduplex/Feria label from the day's own
temporalCategory, since Sundays/ferias aren't on the duplex scale at
all.

A tie between an occurring saint's rank and an active octave now favors
the octave only on its own elevated closing day (live-verified: St.
Hyacinth vs. St. Lawrence's own Aug 17 closing day), not on an ordinary
octave day, where a tied saint still wins as before -- confirmed against
two already-tested counterexamples (St. Thomas of Canterbury, St.
Nicholas of Tolentino) that a blanket tie-flip would have broken.
getDayLabel previously dropped every commemoration whenever the day's
winner was a plain saint, and dropped every non-headline active octave
even when an octave itself won -- both fixed. Rank is now shown after
the day's own winner's name (previously not shown anywhere in the UI).
Also authored assumption-octave-day-3.yml, a real content gap (Aug 17,
day 3 of her octave) surfaced while fixing the above.
St. Charles Borromeo (11-04), the Octave Day of All Saints (11-08,
own real Cyprian/Augustine Nocturn 2-3 content, collect reused from
All Saints via cross-id propers), St. Albert the Great (11-15),
St. Gertrude (11-16), St. Felix of Valois (11-20). All Souls' Day
(11-02) deliberately skipped -- a Requiem office, not a normal
saint's office, a genuine mechanism gap.
Several new fixed-date Duplex+ saints displaced existing test
fixtures that had assumed particular dates were clean/ferial/
plain-Sunday: prime.test.ts's MONDAY constant, weekday.test.ts's
clean-Sunday case, and day-label.test.ts's post-Epiphany-overflow
and open-octave-day cases. Fixed by finding genuinely clean
alternate dates/years, never by weakening assertions.

Continues the full-year sanctoral import: the Guardian Angels (Duplex
majus, full proper content), St. Thérèse of Lisieux, St. Bruno, St.
Bridget of Sweden, St. Francis Borgia, the Maternity of the BVM (Duplex
II Classis, instituted 1931 for the 1500th anniversary of the Council
of Ephesus, full proper content), St. Edward the Confessor, St. Teresa
of Avila (distinct from St. Thérèse of Lisieux -- two different
Carmelite saints sharing a name), St. Margaret Mary Alacoque, St. Peter
of Alcantara, St. John Cantius, and St. Raphael the Archangel (own
full proper content, matching st-gabriel-archangel.yml's established
pattern for a Sancti file that redirects wholesale to another date's
file but still carries its own real content).
St. Raphael's new fixed day (Oct 24, Duplex majus) collided with the
"clean, empty Saturday" fixture used by three tests for Marian
Saturday/Lauds-psalmody-override behavior; moved all three to 2026-07-04,
verified genuinely free of any sanctoral entry (not even a commemorated
Simplex).

Continues the full-year sanctoral import: St. Stephen of Hungary, St.
Pius X, St. Lawrence Justinian, Ss. Protus and Hyacinth, the Holy Name
of Mary, the Seven Sorrows of the BVM (Duplex II Classis, own full
proper content except Nocturn 2, a real cross-reference to Passion
Friday's own temporal content), the Impression of the Stigmata of St.
Francis, St. Joseph of Cupertino, Our Lady of Ransom, and St.
Wenceslaus.
Ss. Protus and Hyacinth (Sep 11) were previously excluded under a
stale "real secondary saint blocked by the Nativity's own octave, same
as St. Clare in August" note -- wrong, same class of error already
corrected for St. Tiburtius/Susanna in August: the octave-window
exclusion was never a real rule. Sep 15 (day 8 of the Nativity's own
octave) is now also the Seven Sorrows' own fixed day (Duplex II
Classis), which wins outright with the octave still commemorated
alongside her -- updated september-sanctoral.test.ts's own "excluded
secondary saints" case accordingly, splitting it into the still-valid
Sep 9 (Gorgonius) half and a new Sep 15 case reflecting the real
winner.

Continues the full-year sanctoral import: Ss. Tiburtius and Susanna, Ss.
Hippolytus and Cassian, the Vigil of the Assumption, St. Joachim (Duplex
II Classis, own full proper content), St. Hyacinth, St. John Eudes, St.
Jane Frances de Chantal, the Immaculate Heart of the BVM (Duplex II
Classis, instituted 1942, full proper content), St. Joseph Calasanctius,
and St. Raymond Nonnatus.
Several of the new fixed dates (Aug 16, 17, 21, 22) fall within or
adjacent to St. Lawrence's and the Assumption's overlapping octave
windows and now win outright there under the ordinary-feria/ordinary-
sunday precedence rules, displacing what several existing tests
expected to be bare octave commemorations or ferial fallbacks. Updated:
- august-sanctoral.test.ts: Aug 22 now correctly shows the Immaculate
Heart of Mary as the winner, with the Assumption's octave still
commemorated alongside her.
- day-label.test.ts: the two octave-priority tests pinned to Aug 17
(now St. Hyacinth's own day) moved their "day 8 alone" case to All
Saints' own octave (Nov 8, still open); the two-octaves-overlap
comparison can no longer be demonstrated via any real date in this
app since every day where St. Lawrence's and the Assumption's octaves
genuinely overlap is now real sanctoral content -- the underlying
`pickWinningOctave` mechanism itself stays covered by
tests/calendar/octaves.test.ts's own synthetic-data unit test.
- vespers.test.ts: the Thursday Ps 138 split test moved off Aug 20,
whose own first Vespers is now claimed by St. Jane Frances de
Chantal's fixed day (Aug 21).

Continues the full-year sanctoral import: the Most Precious Blood of Our
Lord (Duplex I Classis, full proper office, elevated by Pius XI for the
1933 Redemption jubilee), the Visitation of the BVM (Duplex II Classis,
full proper office), St. Leo II, St. Anthony Mary Zaccaria, the Octave
Day of Ss. Peter and Paul (own real content, not a bare continuation),
Ss. Cyril and Methodius, St. Elizabeth of Portugal, St. Henry, Our Lady
of Mount Carmel, St. Vincent de Paul, and St. Ignatius of Loyola.
Also fixes a real pre-existing bug surfaced while authoring St. Leo II:
an earlier June sanctoral pull had mapped him to "06-28" (his own vita
text mentions his burial "upon the 28th day of June," but his actual
liturgical feast, per the reference engine's Sancti/07-03.txt, is July
3) with no saints/st-leo-ii.yml ever authored for it -- a wrong-date
stub, same class of artifact as the pre-existing St. Apollinaris
wrong-date bug already documented in july-sanctoral.test.ts. Removed
the stale June 28 entry now that he's correctly authored on July 3.
Two day-label tests pinned to Trinity-Sunday-relative dates that now
collide with new fixed feasts (Jul 6: Octave Day of Ss. Peter and Paul)
were moved to collision-free years/dates, and the July stub test
covering "pure octave-continuation days" was updated to a date (July 4)
that's still genuinely unmapped, since most of that range turned out to
have real content after all.

Continues the full-year sanctoral import: St. Angela Merici, St. Francis
Caracciolo, St. Boniface of Mainz (Bishop and Martyr, Apostle of Germany --
distinct from the earlier, unrelated St. Boniface Martyr already on May 14),
St. Norbert, St. Margaret of Scotland, and St. Aloysius Gonzaga.
Two of the new fixed dates (June 1, June 4) fall on dates used by two
day-label tests pinned to specific Trinity Sunday years; moved those to
years/dates free of the new entries, with explanatory comments.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Continues the full-year sanctoral import (see TODO.md/memory for Jan-Apr):
St. Pius V, St. Antoninus, St. Robert Bellarmine, St. John Baptist de la
Salle, St. Paschal Baylon, St. Venantius, St. Bernardine of Siena, St. John
Baptist de Rossi, St. Augustine of Canterbury, St. Mary Magdalene de Pazzi,
and the Queenship of the BVM (May 31, Duplex II Classis, instituted by Pius
XII's 1954 "Ad cæli Reginam" — full proper content, not a Common fallback).
Adding the Queenship to May 31 surfaces a real collision with Trinity
Sunday in years where Trinity falls on May 31 (2026): since this app
models Trinitytide Sundays as plain ordinary-sunday with no special
first-class standing, a Duplex+ sanctoral feast wins outright there per
the existing precedence rule. Updated the two tests pinned to that date
accordingly, with a third moved to a Trinity Sunday date (2023-06-04)
free of any sanctoral entry to keep testing the octave-vs-anchor-day
interaction in isolation.

Purification of the BVM (Feb 2), St. Andrew Corsini (Feb 4), St. John
of Matha (Feb 8), Apparition of the Immaculate BVM at Lourdes (Feb 11),
Ss. Seven Founders of the Servite Order (Feb 12), St. Gabriel of Our
Lady of Sorrows (Feb 27) -- all had real, complete Matins content in
the reference engine and no exclusion comment; simply never reached
during the earlier month-by-month sanctoral pulls. Continuing the same
sweep as January's St. Francis de Sales/St. Martina/St. John Bosco.
Test update (not a regression): St. Andrew Corsini transfers onto Feb 5
in years where Sexagesima falls on his own Feb 4, outranking St. Agatha
when it does -- february-sanctoral.test.ts's proof year for Agatha
moved from 2029 (now a collision year) to 2025 (clean).
npm test (365 tests) and tsc --noEmit both pass.

Finding of the Holy Cross (May 3), the Transfiguration (Aug 6), the
Exaltation of the Holy Cross (Sep 14), and Dedication of the Basilica of
the Most Holy Savior (Nov 9, the Lateran) were all excluded under the
same stale "fixed feast of the Lord, not modeled" note that turned out
wrong for Our Lady of the Snows. All four have real, complete content in
the reference engine. Presentation of the BVM (Nov 21) was excluded
under the equivalent "fixed BVM feast" note and is added the same way.
- finding-of-the-holy-cross: fully proprium, own collect/antiphon/Matins
throughout; now correctly outranks
ss-alexander-eventius-theodulus-and-juvenal, matching what that
saint's own file already documented as the live reality.
- transfiguration: same proprium shape. Its subordinate saints (Ss.
Xystus/Felicissimus/Agapitus) stay excluded -- blocked by the real,
separate octave/subordination-rendering gap, not by an unmodeled
Transfiguration.
- exaltation-of-the-holy-cross: reuses the Finding of the Holy Cross's
content wholesale (ex Sancti/05-03) -- collect/antiphon via a cross-id
`propers` pointer, Matins nocturn-readings duplicated (no cross-id
lookup exists for that mechanism).
- dedication-of-the-basilica-of-the-most-holy-savior: reuses the
existing Common-of-a-Dedication (collect-c8, benedictus-antiphon-
common-of-a-dedication), real unique Nocturn 2 vita of her own. Her
secondary, St. Theodore, stays excluded for the same
octave/subordination reason as above.
- presentation-of-the-bvm: real unique collect of her own; her
Benedictus antiphon is a substituted Common reference
(truncate-and-add-alleluia edit specific to this feast), authored as
her own file.
Also: our-lady-of-the-snows.yml was missing its own Nocturn 3 (she
defers to Commune/C11's own Gospel-incipit-plus-Bede-homily, same as
Presentation of the BVM) -- added.
Test updates (not regressions): three tests had fixed proof dates
colliding with the newly-added feasts, updated to reflect the new,
correct behavior. npm test (365 tests) and tsc --noEmit both pass.

Post-Pentecost overflow years (early Easter, fewer than 6 Sundays after
Epiphany fit before Septuagesima) previously clamped every excess Sunday
to post-pentecost-24 instead of resuming the skipped post-Epiphany
Sundays' own content, per the traditional rubric. Ported directly from
the reference engine's own DivinumOfficium/Date.pm getweek().
Also adds the Epiphany VI Saturday-before-Septuagesima commemoration
(only when Epiphany V was the last Sunday to actually occur), and fixes
day-label.ts's on-screen display to track the same resumed-Sunday
content instead of a raw elapsed-week count — including a correction so
the fixed final Sunday of the year always reads "23rd Sunday after
Trinity", not a per-year-varying number.

Whichever of today/tomorrow doesn't govern a given evening's Vespers
can still be commemorated there, unless it's Simplex (or a bare
temporal winner with no standing of its own) — live-verified in both
directions against the real Monastic 1617 engine: Ss. Cyriacus/Largus/
Smaragdus (Semiduplex) commemorated when Sunday claims First Vespers
over them; St. Anne commemorated even though St. James (Duplex II.
classis) keeps his own Second Vespers outright; St. Donatus (Simplex)
gets nothing ("nihil de præcedenti") in the same situation Cyriacus/
etc. did get a commemoration. The isMajorFixedFeastOfTheLord override
(Christmas/Epiphany/Candlemas/Easter/Ascension/Corpus Christi/Sacred
Heart) deliberately doesn't inherit this yet — no live data on whether
those suppress it the way privileged-sunday/privileged-feria-major do
during the day.
Also fixes hasFirstVespers's threshold, found wrong while gathering
the above evidence: it required duplex-majus+, but Ss. Cyriacus/etc.
(plain Semiduplex) actually claims First Vespers over St. Donatus in
the live engine. Lowered to semiduplex, matching the sibling
privileged-feria-minor threshold already used just below it.

Follow-up to the previous commit: applies the same "read the fileref
directly, no live query required" fix to St. Frances of Rome and St.
Bibiana, whose own filerefs simply hadn't been derived yet (they predate
the Kalendaria-table work this session built). Both resolve to
common-of-a-virgin, same as several of the 15 fixed previously.
Also swept every saint on the calendar (not just this batch's own
lineage) for any other still-missing collect or Benedictus antiphon,
which turned up a real, older gap: St. Agatha and St. Lucy's own file
comments already documented "resolves honestly missing... despite
propers being set" -- written before collectCommon existed as a
mechanism at all. Agatha's own [Oratio] is a name-substituted reference
confirmed identical to the already-existing collect-c6.yml template, so
collectCommon was simply wired in. Lucy's own [Oratio] references a
different Common formula unedited, with her own [Name] section supplying
the whole descriptive phrase a plain name field would otherwise need the
template for -- written as her own st-lucy-collect.yml rather than a new
single-use template, since she's the only current user of that unedited
form.
St. Clare showed up in the same sweep but is a false positive: her real
content lives in a separate commemoration-bundle file, used via a
different code path the sweep's synthetic-winner methodology doesn't
exercise -- already fully authored, no gap.

Blind per-date source-file reading (Sancti/SanctiM MM-DD.txt) turned out
unreliable for collect authorship: those files are era-merged, carrying
centuries of accumulated saints behind rubric-conditional gating, so a
naive read often returned a saint canonized long after 1617 instead of
the Monastic-Tridentine-era one actually on this calendar (St. Didacus
instead of All Saints of the Benedictine Order, St. Rose of Lima instead
of Ss. Felix and Adauctus, etc).
Fixed by pulling from web/www/Tabulae/Kalendaria/'s own era-specific
calendar tables (1570.txt Tridentine base + M1617.txt's Monastic diffs)
instead, cross-validated against the pre-1955/Divino Afflatu chain
(1888->1906->1939->1954) as a corroborating signal. Cross-referencing all
205 existing saint records against this table confirmed 204/205 were
already correctly placed -- the earlier live-query verification work was
sound, only blind file-reading was flawed -- so no sanctoral-calendar.yml
corrections were needed, just the collect content itself.
Two collect shapes came out of the 94: 34 proper collects (own YAML file,
Latin verified against source, English translated+draft where the source
lacked it) and 60 resolved via a new Common-collect templating mechanism
-- SaintRecord.collectCommon/collectName plus substituteName() in
resolve-common.ts, filling a template's {N} placeholders positionally
from the saint's own declined name, across 21 new common/collect-c*.yml
templates named after the source's own C-numbering.
St. Michael's Sep 29 propers resolved via its whole-file @Sancti/05-08
inheritance (Apparition of St. Michael, May 8). St. Martha's plural-
template default was overridden to the singular collect-c6a since she's
one person, not a pair.
Also fixes a latent bug this surfaced: getDayCollect looked up
`${collectCommon}-collect`, but collect-c*.yml files are id'd as
`collect-c2` etc with no such suffix -- caught by a smoke test where
every one of the 93 non-Michael saints resolved as missing.
4 pre-existing tests updated: they asserted specific saints (St.
Benedict, St. Romanus Abbot, St. Anthony Abbot) had no authored collect,
which is no longer true; resolve-common.test.ts's generic "missing" case
now uses a synthetic day/winner since no real unauthored saint remains
as an example.

Per direct instruction, and explicitly framed as this project's own
departure from Monastic 1617 itself: within Dec 26-30 inclusive (exactly
one real Sunday falls somewhere in that window every year), whichever
date is the actual Sunday always wins as Nat1-0 outright, with no rank
check at all -- even Stephen/John/Holy Innocents (Duplex II. classis)
get fully displaced, not just commemorated. The displaced saint isn't
commemorated in place either; he reappears in full as Dec 30's own
winner instead (the block's one date with no fixed saint of its own).
Rank never matters for this rule -- confirmed with Becket (Semiduplex)
transferring the same way as the Duplex-II-classis saints.
This deliberately diverges both from what Monastic 1617 itself does on
Dec 26-29 (live-verified two commits ago: the saint wins there, Sunday
merely commemorated) and from the general privileged-sunday transfer
rule elsewhere (which only transfers ranks below duplex-majus and
commemorates everything else in place) -- this window transfers every
rank and commemorates nothing in place, a genuinely new, third
behavior specific to this 5-day block.
Implemented as calendar/index.ts's applyChristmasOctaveSunday, a
narrowly-scoped layer in the same spirit as applyMarianSaturday/
applyChristTheKing, rather than by changing the shared
decideOccurrence/transfer machinery every other Sunday relies on. Dec 31
and everything outside Dec 26-30 is untouched -- St. Silvester still
beats the Sunday there via the plain, unchanged ordinary-sunday rule.
Verified against all five possible Sunday positions within the window
(Dec 26/27/28/29/30) plus the "nothing displaces anything" control case,
each with its own dedicated test in the new
tests/calendar/christmas-octave-sunday.test.ts. Updates two existing
tests whose assertions were correct under the old rule and are now
superseded specifically within this window (Stephen/Innocents no longer
win their own Sunday-collision dates there) while confirming the
underlying ordinary-sunday rule is still live and real outside it (Dec
31/St. Silvester).
