18 saints for May (16 real + 2 stubs). Both stubs this month are
genuinely unwinnable in the real historical calendar in any year (their
competing observances are fixed-date, not movable) — flagged explicitly
in their own files as distinct from the usual "just an artifact of the
year checked" caveat.
A second, distinct feast of St. Michael (his Apparition, May 8) is kept
as its own record separate from st-michael.yml's Sept 29 dedication
feast, same precedent as the two Chair-of-Peter feasts.

12 saints for April (11 real + St. Catherine of Siena as a stub), all
winning outright on a clean per-annum date.
Two real methodological findings this month:
- St. Mark (Apr 25, Duplex II. classis) directly confirms the
privileged-feria-major behavior from the previous fix: he only ever
gets commemorated within the Easter Octave, never wins there.
- St. Robert/St. Catherine of Siena (Apr 29) is a genuine, year-stable
monastic-calendar reassignment — this app's own base Latin source data
files that date's Roman-calendar content under a different saint (Peter
Martyr) entirely, which a naive raw-file lookup by MM-DD would have
missed; the live per-date query resolved it correctly regardless, and
is what these records are actually built from. Worth remembering for
future months.
New common category: common-of-an-evangelist (St. Mark, an Evangelist
but not an Apostle).

7 saints for March, all winning outright on a clean per-annum date. Notably
St. Benedict himself (Mar 21, Duplex I. classis, the founder — "S. P. N."
in the source) turns out to have no unique Oratio/Antiphon at all in this
date's source file, only Common-of-an-Abbot cross-references — flagged in
his own file to check his second (July) feast when that month comes up.
Two Benedictine-oblate saints (Frances of Rome, Gregory the Great) are
marked "O. N." (Ordinis Nostri) in the source — real significance for a
monastic calendar. St. Frances also needed a new common category,
common-of-a-widow (she's neither virgin nor martyr).

13 saints for February (12 real + the Vigil of St. Matthias), all
verified winning outright on a clean per-annum date — no secondary/
commemorated stubs needed this month, unlike January.
Two new scope exclusions found this month, beyond the usual octave/
temporal-continuation and fixed Lord/BVM feast ones: the generic
"Sanctae Mariae Sabbato" Saturday votive (not a real saint) and Feb 29's
leap-year redirect of the Vigil of St. Matthias (a real but not-yet-
modeled leap-day date shift).

20 saints for January, verified per-day against Divinum Officium (Monastic
Tridentinum 1617): 13 that actually win their day outright (rank pulled
from a live per-date query, since the static 1570/M1617 calendar text
files turned out unreliable once monastic-specific overrides apply) and
7 stubs for saints that only ever get commemorated, with an explicitly
flagged, unverified simplex rank guess pending correction.
Deliberately out of scope: pure octave-continuation days (In Octava S.
Stephani, the Epiphany-octave ferias) and fixed-date feasts of the
Lord/BMV (Circumcision, Epiphany) — sanctoral only, not temporal.

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.
Replaces the FeastRank placeholder with a real ordered FeastClass (the old
pre-1955 six-level scale) and a new TemporalCategory (privileged/ordinary
Sunday/feria). calendar/commemorations.ts's decideOccurrence encodes the
actual precedence rules as explicit, commented branches per category
rather than the reference engine's own opaque numeric weights — this app
targets one ruleset, so the readability trade-off is worth it. Category
membership (data/calendar/temporal-categories.yml) is a best-effort
reconstruction of the pre-1955 tradition, not sourced from a primary text;
expect corrections.
calendar/feasts.ts resolves real sanctoral candidates, and resolveDay()
wires it all together — occurring/temporalCategory are no longer stubs.
isDoubleOrHigher (hours/antiphon.ts) is now a real comparison instead of
a hardcoded false.
Seeded 7 real saints/feasts, each verified directly against Divinum
Officium's own rank data (not reconstructed from memory) as a small,
growable start: St. Lawrence, the Assumption, St. Augustine, the Nativity
of the BVM, St. Michael, All Saints, the Immaculate Conception.
Client-side-first PWA (Vite/TS, no backend) per the approved plan: day-
navigable shell listing all 8 hours, Prime fully resolves via the
calendar -> psalter -> ordo pipeline, the other 7 hours are registered
but flagged not-implemented. Sanctoral/temporal calendar data uses a
day -> id indirection layer (saints, easter-offsets, fixed-date-calendar)
so reassigning a feast to a different day is a data edit, not a code
change. Docker (Caddy-serving-static) + Gitea CI workflow scaffolded to
match the eec/drip/bookshop operational pattern.
