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.

Two related fixes surfaced while chasing why St. Gregory Thaumaturgus
appeared to be misdated on Nov 18:
- calendar/commemorations.ts's `ordinary-sunday` case was transferring a
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: 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.

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.

When more than one octave is active on a day with no temporal standing of
its own (St. Lawrence's and the Assumption's genuinely overlap every Aug
16-17), which one governs the day's content/label is now decided by rank
comparison instead of "whichever started first" (an accident of
insertion order). Per direct instruction:
- Highest effective rank wins outright; every other active octave still
gets commemorated, same as a single octave already outranking a weak
rival saint.
- A rank tie goes to whichever octave started more recently -- day 1 of
a new octave needs to be fully present, the whole point of it
starting. No real tied-rank case exists yet to verify this
empirically, unlike everything else here -- documented in TODO.md as
a stated decision, not a live finding.
New OctaveConfig.closingDayRank (default duplex): an octave's own final
day ("in Octava") is elevated above its ordinary in-between rank --
live-verified as a real, general pattern (both St. Lawrence's Aug 17 and
the Assumption's Aug 22 show as Duplex, above their otherwise-Semiduplex
ordinary days), not a one-off. This elevation is *why* Lawrence's octave
beats the Assumption's on their one real overlap day despite the
Assumption being the far higher-ranked feast overall. Feeds both the
existing rival-saint threshold and the new octave-vs-octave comparison.
calendar/octaves.ts gains resolveActiveOctave (+ pickWinningOctave, the
comparison itself factored out for direct unit testing against synthetic
data, since no real tied-rank overlap exists to test against yet).
hours/resolve-common.ts's resolveOfficeWinner and calendar/day-label.ts
both now call it instead of each keeping their own "activeOctavesFor(...)
[0]" logic.
That consolidation surfaced a real, independent bug: getDayLabel never
checked temporalCategory at all before choosing an octave name, unlike
resolveOfficeWinner -- found while testing the real Aug 16 overlap (a
Sunday that year, where the temporal Sunday has standing and should win
outright). Live-verified counterexample: the Christmas Octave's own
stack (Dec 30) was wrongly labeled "3rd Day within the Octave of The Holy
Innocents" instead of the correct plain temporal label -- the real title
never names any of the four stacked octaves there. Fixed by sharing the
exact same ordinary-feria gate resolveOfficeWinner already had, so the
two can no longer disagree.

Today (Aug 12, within St. Lawrence's octave) was resolving as a plain
ferial day: St. Clare wasn't modeled in the calendar at all, and even
once an octave commemoration exists, getDayLabel only ever looked for a
sanctoral commemoration, never an octave one, so the label fell all the
way through to the generic ordinal week label.
Adds St. Clare (Simplex under Monastic 1617, correctly losing to
Lawrence's octave and only commemorated -- live-verified against three
clean years). Extends getDayLabel to show the active octave itself as
the day's primary identity when nothing else has won outright (e.g.
"3rd Day within the Octave of St. Lawrence, Martyr -- St. Clare,
Virgin"), matching what the live reference engine actually titles these
days, rather than falling back to an anonymous ordinal week label.
Also fixes a regression this surfaced: Trinity Sunday is technically
also day 8 of Pentecost's own octave, and the naive octave-first check
was shadowing its own anchor-day name ("8th Day within the Octave of
Pentecost" instead of "Trinity Sunday"). A season's own named anchor day
now always outranks an active octave label.

Adds calendar/octaves.ts: a lookback over the past week collecting every
octave (sanctoral or temporal) still active on a date, stacking multiple
at once (Christmas + St. Stephen + St. John + Holy Innocents all
commemorated together within the Christmas Octave). Declared via an
optional `octave` field on a saint's own record or a new small
TemporalFeastRecord (calendar/temporal-feasts.ts) for temporal ids like
Christmas/Pentecost that didn't have a metadata record before -- data-
driven per user design discussion, with `{ enabled: true }` alone using
sensible defaults (8 days, semiduplex threshold) so a minimal declaration
works without authored content.
Wired into resolveDay as a post-processing layer: doesn't change how a
single day's own precedence contest is decided, just adds commemorations
for active octaves and occasionally overrides the winner when the
occurring saint doesn't clear the strictest active octave's threshold.
Populated so far: St. Lawrence's own octave (the one that repeatedly cost
real saints their spot in August), the three Comites Christi octaves
(Stephen/John/Innocents -- Thomas of Canterbury deliberately excluded,
per discussion), and Pentecost's (duplex threshold, user-specified).
Pentecost's octave offsets are also removed from temporal-categories.yml's
privileged-feria-major classification, letting a real candidate reach the
new octave layer instead of being transferred away first -- with the
side effect that Pentecost's own Ember Saturday no longer forces a
transfer (a sub-threshold saint is now commemorated in place instead, see
tests/calendar/transfer.test.ts's updated case). Assumption, Nativity
BVM, Immaculate Conception, and All Saints' own octaves are not yet
populated with octave data -- deliberately deferred to a follow-up pass.

9 collects, 3 antiphons -- including backfilling the pre-existing All
Saints entry. Also updates two pre-existing tests whose shared date
(2025-11-30, Advent I Sunday) now correctly shows St. Andrew commemorated
alongside it, confirmed against the live reference engine.

Found via real data (the May sanctoral pull): a transfer landing on a day
whose own native winner was temporal blindly took over as winner,
regardless of that day's own precedence category — so a transferred-in
Simplex saint (St. Felix I, impeded by Pentecost's Ember Saturday) was
overwriting Trinity Sunday itself instead of being merely commemorated,
the way a native Simplex candidate on an ordinary Sunday already
correctly is.
Fixes applyIncomingTransfer to run the arriving candidate through
decideOccurrence using the receiving day's own temporalCategory, the same
rules a native occurrence there would use, instead of assuming an empty
temporal slot means automatic victory.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Corrects and completes the occurrence rules, based on a design discussion
plus one concrete data point: St. Anthony Abbot (plain Duplex) was found
outright winning against an ordinary Sunday in the real Monastic 1617
engine, which the old duplex-1-classis-only threshold got wrong.
- FeastClass gains `vigil`, inserted between `simplex` and `semiduplex` —
one ordering that correctly serves both "does this win against a Sunday"
(vigil behaves like simplex there) and "which of two saints wins a
landing-day collision" (vigil beats simplex, loses to semiduplex).
- LiturgicalDay.occurring (a flat OccurringFeast[] that could only ever
express a losing *sanctoral* candidate) is replaced by `winner:
DayWinner` + `commemorations: Commemoration[]` — a discriminated list
that can hold the temporal day itself, one or more sanctoral entries, or
(not built yet, but the shape already accommodates it) a future octave
kind.
- commemorations.ts: ordinary Sundays let Duplex+ win outright (Sunday
commemorated in return), Semiduplex/Vigil transfer elsewhere (too
substantial a feast to cheapen with a bare commemoration), Simplex stays
and is commemorated. Privileged Sundays never displace; Duplex-majus+
commemorated, everything else transfers.
- collision.ts (new): resolves two sanctoral candidates wanting the same
day (a transfer landing on an already-occupied day, or two native
saints sharing a date) — duplex > semiduplex > vigil > simplex, loser
always commemorated, ties favor the native occupant.
- temporal-id.ts (new): maps any date to one of the 52 real Sunday-collect
ids from the previous commit, so a temporal winner/commemoration can
actually be looked up, not just labeled "temporal" in the abstract.
- index.ts's resolveDay orchestrates all of it, including the actual
Monday/Saturday transfer mechanism. Landing on a privileged feria (the
concrete case: Holy Week, right after Palm Sunday) is explicitly
deferred rather than guessed at — it needs its own Easter-keyed lookup
table, the same way the reference engine handles it.
Added the Vigil of St. Lawrence (Aug 9) as real content specifically to
exercise the backward-transfer rule end-to-end: Aug 9, 2026 is a Sunday,
so the vigil transfers cleanly back to Saturday, verified by a new
integration test alongside the unit-level rule and collision tests.
Adds a real label under each hour's heading — "Monday in the 10th week
after Trinity", "The 1st Sunday of Advent" — computed from whichever
LiturgicalDay the hour actually resolved against, which can differ from
the nav date for Compline's evening anticipation.
calendar/day-label.ts combines two things: an ordinal week-within-season
label (pure date arithmetic on the season anchors from calendar/temporal.ts
and calendar/easter.ts — Trinity-counted, not Divinum Officium's own
Pentecost-counted convention; meant to become configurable later via the
same day->id indirection already used for the sanctoral calendar, not
hardcoded forever), and a feast name from calendar/commemorations.ts's
occurrence decision — shown alone if the feast displaces the day outright,
prefixed onto the temporal label if merely commemorated, or omitted
entirely if nothing's occurring.
