Lauds psalmody overrides (duplex-majus+ per-feast psalms/antiphons/canticle)

Mechanism: src/hours/lauds-psalmody-overrides.ts, gated in hours/lauds.ts's getPsalmodyOverrideFor. Only fires for a saint ranked duplex-majus or higher (per direct instruction) or a named temporal feast (marian-saturday, christ-the-king).

Authored (3): st-lawrence, marian-saturday, christ-the-king.

Not authored yet (32 duplex-majus+ saints, sorted roughly by calendar order) — each needs a live command=prayLaudes query on the saint's own date, Monastic Tridentinum 1617, same method as the three done so far:

conversion-of-st-paul, chair-of-st-peter-at-rome, apparition-of-st-michael, st-matthias, st-benedict*, st-mark, ss-philip-and-james, st-john-before-the-latin-gate, st-john-apostle (Dec 27, distinct from st-john-before-the-latin-gate May 6), st-barnabas, nativity-of-st-john-the-baptist, ss-peter-and-paul, chair-of-st-peter-at-antioch, st-james-the-greater, st-martin-of-tours, holy-innocents, st-thomas-apostle, all-saints, all-saints-of-the-benedictine-order*, st-andrew, st-stephen-protomartyr, ss-simon-and-jude, st-luke, st-matthew, st-michael*, st-maurus-abbot*, ss-placid-and-companions*, st-scholastica, st-bartholomew, st-peter-ad-vincula, assumption, nativity-bvm, immaculate-conception.

* = propers: null in the saint's own record — needs collect + antiphon authored too, not just the psalmody override, before any of this is useful.

Lauds office-bundle overrides (capitulum/responsory/hymn/versicle)

Same override id, separate files (lauds-capitulum-<id>.yml etc. in data/propers/common/) — falls back to the plain weekday bundle when absent, independently of whether the psalmody override exists. Authored (2): st-lawrence, christ-the-king. 31 duplex-majus+ saints left — same list as the psalmody overrides above, minus Lawrence.

Prime/Terce/Sext/None minor-hour overrides (2026-08, new mechanism)

Found while investigating why St. Lawrence's octave showed none of his own content at Prime/Terce/Sext/None either — these four hours had no per-feast override mechanism at all before this, unlike Lauds: the psalm antiphon always came from the plain weekday default (data/hours/{hour}-antiphons.yml), and the chapter was always a single fixed per-annum/per-weekday text, regardless of what was actually being celebrated — even on a saint's own actual feast day, not just during an octave.

Mechanism: hours/resolve-common.ts's getMinorHourOverrideId (same duplex-majus+ threshold as Lauds' own override, deliberately kept in sync so it's one shared backlog, not per-hour lists that can drift — see resolveOfficeWinner, which makes this octave-aware the same way Lauds' already is), resolveMinorHourAntiphon, resolveMinorHourChapter. Prime additionally needed isSundayOrFeastOffice (its capitulum/Preces choice between Sunday/feast and ferial forms) made octave-aware — live-verified Prime's capitulum stays the Sunday/feast form (1 Tim 1:17) throughout an octave, not just the feast's own actual day, so no separate override file was needed there, just the existing Sunday-form file reached correctly.

Authored — all 29 duplex-majus+ saints, done (2026-08). Antiphon + chapter for Terce/Sext/None, antiphon only for Prime (its chapter needed no new file — see above), for every id in the Lauds backlog list above except the 5 propers: null-blocked saints (st-benedict, all-saints-of-the-benedictine-order, st-michael, st-maurus-abbot, ss-placid-and-companions) — those still need a collect authored first. Two saints (st-scholastica, immaculate-conception) needed corrections to the reference engine's own data: Scholastica's minor hours have no English rendering at all in the source (Matins-only English coverage for that saint) — translated directly, status.en: draft throughout; Immaculate Conception's antiphons render with diacritics stripped compared to the word-for-word-parallel Nativity BVM antiphon — restored accentuation to match, status.la: draft.

Prime/Terce/Sext/None Commons extraction (2026-08)

After the P/T/S/N batch above landed, a systematic diff across all 29 saints' files (not just the pairs noticed in passing during authoring) turned up real shared-Common groups, extracted into data/propers/common/ {hour}-antiphon-common-of-*.yml / {hour}-capitulum-common-of-*.yml files and wired via a new SaintRecord.minorHoursCommon field (calendar/feasts.ts) — resolveMinorHourAntiphon/resolveMinorHourChapter (hours/resolve-common.ts) now fall back to it when a saint has no proper file of their own for a given hour. Deliberately a separate field from the existing (until now unused) common field: live-verified the minor hours don't always draw from the same Common category as the saint's overall classification (see the Confessor-Bishop group below) — reusing common directly would have gotten that case wrong.

Four groups extracted, all confirmed byte-identical via diff first, none assumed from category alone:

• common-of-apostles (all 4 hours, antiphon + chapter): st-matthias, st-barnabas, st-james-the-greater, st-thomas-apostle, ss-simon-and-jude, st-luke, st-matthew, st-bartholomew — 8 saints, 56 duplicate files collapsed to 7 shared ones.
• common-of-a-confessor-bishop: chair-of-st-peter-at-rome and chair-of-st-peter-at-antioch share all 4 hours' antiphons and chapters; st-martin-of-tours shares only the chapters (his own antiphons are proper, about his own life). Real finding, not a modeling choice: both Chair feasts are common: common-of-an-apostle in their own saint record (Peter's rank/collect classification), but their P/T/S/N content comes from the Common of a Confessor Bishop instead — Peter considered as bishop of that particular see, for that specific commemoration.
• common-of-the-bvm (chapter only, Terce/Sext/None): nativity-bvm and immaculate-conception share all three; their own antiphons stay proper (per-mystery). The Assumption's Sext/None chapters share the same reading body (Sir 24:15-16, 24:19-20) but close with her own proper versicles rather than the Common's plain ones, and her Terce chapter is a different reading entirely (Sir 24:11-12, not 24:14) — a first-class feast's proper office outranking the plain Common, kept as her own fully proper files rather than force-fit into the shared one.
• common-of-st-peter (None antiphon, all 3 chapters): st-peter-ad- vincula and ss-peter-and-paul. Not a real liturgical Common category — both feasts are specifically about St. Peter himself, so his own proper texts get reused directly. Extracted anyway since the content really is identical, just named honestly rather than dressed up as a Common of Saints class.

Paschaltide commons — done (2026-08)

The Mark/John-Before-the-Latin-Gate/Philip-and-James "Alleluia" text flagged above as an open question is confirmed real, not a coincidence: the reference engine's own source has explicit Paschaltide variants — Commune/C1p.txt/C2p.txt/C3p.txt ("Commune Apostolorum/Unius Martyris Pontificis/Plurimorum Martyrum tempore Paschali") — for exactly 3 of its 12 Common categories: Apostles, a Martyr-Bishop, Several Martyrs. Confessors/Virgins/Doctors/BVM never get one — Alleluia/victory imagery is restricted to apostles and martyrs specifically, a real liturgical distinction, not an app gap.

Mechanism: resolveMinorHourAntiphon/resolveMinorHourChapter (hours/resolve-common.ts) now try ${hourId}-antiphon- ${minorHoursCommon}-paschaltide (etc.) first whenever day.season is eastertide, ascensiontide, or pentecost — the same three-season window as Compline's own Regina Caeli table (data/hours/marian-antiphon-by-season.yml), not just eastertide alone, since "tempore paschali" runs through the Pentecost octave in both cases. Falls back to the plain (non-Paschaltide) Common when no -paschaltide variant is authored, same silent-fallback convention as everywhere else.

common-of-apostles-paschaltide (7 files) ported directly from Commune/C1p.txt/English Commune/C1p.txt — not live-queried — and cross-checked against st-mark's already-authored, live-queried content (2026-04-25): identical except the source's own Prime-antiphon asterisk falls one word earlier than the live-rendered incipit had suggested, corrected here to match the source. st-mark and st-john-before-the- latin-gate's own duplicate per-saint files removed (all 7 each); ss-philip-and-james's chapter files removed (its own antiphons stay proper — its own Gospel-referencing text, not shared even in Paschaltide). Only C1p (Apostles) ported so far, since no currently- authored saint sits on a Martyr-Bishop or Several-Martyrs common that could fall in Paschaltide — common-of-a-confessor-bishop and any future Martyr-common saint don't need one (Confessors never get a Paschaltide variant at all; a Martyr one would need porting C2p/C3p the same way, if and when a saint needing it is authored).

Overlapping octaves — done (2026-08)

Was: resolveOfficeWinner/getDayLabel picked whichever active octave started first whenever more than one was active — an accident of insertion order, not a real precedence rule. St. Lawrence's octave (Aug 10-17) and the Assumption's (Aug 15-22) genuinely overlap on Aug 16-17 every year, so this wasn't hypothetical.

Design (per direct instruction, not independently re-derived from a primary source the way most of this project is): when more than one octave is active on a day with no temporal standing of its own to yield to first, compare them by rank — highest wins outright, exactly like a single octave already out-ranks a weak rival saint; every other active octave still gets commemorated, never silently dropped. A rank tie goes to whichever octave started more recently — reasoning given: day 1 of a newly started octave needs to be fully present, which is the whole point of an octave starting, so the older one yields instead. No real tied-rank case exists yet in this app's calendar to verify that empirically, unlike almost everything else in this project — flagged as a stated, unverified-by-evidence design decision, not a live finding.

Also needed OctaveConfig.closingDayRank (default duplex): an octave's own closing day ("in Octava," the 8th/final day) is elevated above its ordinary in-between-days rank — live-verified as a real, general pattern (not a St. Lawrence quirk): both his own Aug 17 and the Assumption's own Aug 22 show as Duplex, above their otherwise-Semiduplex ordinary days. This is why Lawrence's octave beats the Assumption's on their one real overlap day (Aug 17) despite the Assumption being the far higher-ranked feast overall (Duplex I. classis vs. Lawrence's Duplex II. classis) — his closing-day elevation (Duplex) beats her ordinary day-3 strength (Semiduplex). Feeds both strictestThreshold (a rival saint now needs Duplex+, not just Semiduplex+, to beat an octave specifically on its own closing day) and the new octave-vs-octave comparison (calendar/octaves.ts's resolveActiveOctave/pickWinningOctave) — same underlying "how strong is this octave today" question, two different comparison partners.

getDayLabel was carrying its own separate, never-actually-correct octave-selection logic that additionally never checked temporalCategory at all — found while testing the real Aug 16 overlap (a Sunday that year): it was showing an octave name even though the temporal Sunday has real standing and wins outright, live-verified counterexample being the Christmas Octave's own stack (Dec 30), which was wrongly showing "3rd Day within the Octave of The Holy Innocents" instead of the correct plain temporal label. Fixed by having getDayLabel share the exact same ordinary-feria gate and resolveActiveOctave call as resolveOfficeWinner, so the two can never disagree about which identity governs a day.

Dec 26-30's own Sunday rule — done (2026-08), a deliberate remix

Per direct instruction — a real, admitted departure from Monastic 1617 itself, not something independently verified live the way almost everything else here is: within Dec 26-30 inclusive (every year contains exactly one real Sunday somewhere in that 5-day window), whichever date is the actual Sunday always celebrates Nat1-0 (the Sunday within the Octave of the Nativity) outright, with no rank check at all — even a Duplex-II-classis saint (Stephen/John/Innocents) is fully displaced, not just commemorated. The displaced saint isn't commemorated in place either; he reappears in full as the day's own winner on Dec 30 instead — the block's one date with no fixed saint of its own. On a year Dec 30 itself is the actual Sunday, nothing is displaced and it resolves clean.

This intentionally diverges from what Monastic 1617 itself does on Dec 26-29 (there, live-verified, the Duplex-II-classis saint wins and the Sunday is merely commemorated — see the December-sanctoral tests) and from the general privileged-sunday transfer rule elsewhere in this app (which only transfers ranks below duplex-majus and commemorates everything at or above it in place) — this window transfers every rank, full stop, and never commemorates the loser in place.

Implemented as its own dedicated, narrowly-scoped layer (calendar/index.ts's applyChristmasOctaveSunday, same architectural pattern as applyMarianSaturday/applyChristTheKing) rather than by changing the shared decideOccurrence/transfer machinery other Sundays rely on — deliberately contained blast radius. Dec 31 and everything outside Dec 26-30 is untouched; christmastide's Sunday there still uses the plain ordinary-sunday category as before (St. Silvester still beats the Sunday on Dec 31, live-verified, unaffected by this).

Benedictus antiphons for temporal (non-sanctoral) days — done

<id>-benedictus-antiphon.yml in data/propers/temporal/ — all 54 temporal ids now have one (marian-saturday/christ-the-king from earlier, the 51 numbered Sundays/seasons done in one pass, plus christmas-octave-sunday itself, corrected below).

christmas-octave-sunday correction: originally left unauthored here, on the theory that every date this id can resolve to collides with a specific octave-day saint. Wrong — the reference engine has its own dedicated proper for this Sunday specifically, Tempora/Nat1-0 (web/www/horas/Latin/Tempora/Nat1-0.txt in the reference repo, and its Monastic counterpart under TemporaM/), distinct from the individual per-weekday octave pages (Nat02..Nat09 = the ferias, keyed by day offset from Christmas). Most years the Sunday does lose outright to a Duplex-II-classis octave saint (St. Stephen/St. John/Holy Innocents, whichever Dec 26–28 lands on) and only gets a bare commemoration — that's what the earlier searches kept finding — but 2029-12-30 is a clean year where the Sunday itself wins outright (Dominica Infra Octavam Nativitatis ~ Semiduplex Dominica minor, no commemoration line at all), so that's the date the content was pulled from. Benedictus antiphon: "Dum médium siléntium" / "While all things were in quiet silence" — note the source's own English translation genuinely omits the closing "alleluia" that the Latin has; transcribed as-is, not smoothed over.

Method: rather than hunting for "clean years" one at a time, wrote a script that iterates every day of a test year through this app's own resolveDay, buckets each Sunday by which temporal id actually won, and picks one real date per id straight from the app's own logic — then cross-checked each date's live D.O. title for a saint collision before trusting the content (a handful, mostly on privileged Eastertide/ post-Pentecost Sundays, needed a different year: this app's own privileged-Sunday rule never lets a saint displace those Sundays, but the live reference engine's calendar is bigger than this app's and does let some by-date saint win there, e.g. St. Mark on Easter V some years, "Our Lady of the Snows" — not modeled in this app at all — landing on Post-Pentecost XI whenever the date lines up with Aug 5).

Octave content — mostly fixed (2026-08), one real gap left

Was: getDayCollects skipped a kind: 'octave' commemoration entirely, and every other office part (psalmody, hymn, chapter, Benedictus antiphon) stayed keyed off the plain temporal day underneath the octave — so an ordinary day within e.g. St. Lawrence's own octave showed nothing of his at all, not even a label beyond the day-label line. Root cause: found live (Tridentine 1910, 2026-08-12) that on a day like this, the whole office — chapter/responsory/hymn/versicle, psalm antiphons, Benedictus antiphon, day collect — comes from the octave's own feast, not the plain temporal day; only a weaker commemorated saint on top of that (St. Clare, that same date) gets a separate Ant+V/R+collect block of her own. Fixed via hours/resolve-common.ts's resolveOfficeWinner, used everywhere getDayCollect/getDayCollects/getBenedictusAntiphon/ getPsalmodyOverrideFor used to key off day.winner directly — and getDayCollects now renders a real Ant+V/R+collect bundle for a sanctoral commemoration (${propers}-commemoration.yml, e.g. st-clare-commemoration.yml) when authored, falling back to a labeled bare collect (or a labeled "missing" placeholder) rather than the old unlabeled one that just read "PRAYER … (translation pending)" with no indication whose it was.

Real remaining gap: resolveOfficeWinner deliberately only kicks in when temporalCategory === 'ordinary-feria' (the octave day has no standing of its own) — the live-verified counterexample is the Christmas Octave's own stack (Christmas + Stephen + John + Holy Innocents, e.g. on Dec 30, privileged-feria-minor): the temporal day itself keeps the office there ("Dominica Infra Octavam Nativitatis", {ex Proprio de Tempore}), and each of the four octaves gets its own separate "Commemoratio Octavæ …" Ant+V/R+collect block instead — not yet modeled; those four octave commemorations still contribute nothing but a name in the day label.

Benedictus antiphons for every sanctoral/temporal entry (in progress)

Full scope, corrected after actually enumerating it (an earlier pass here under-counted): 109 sanctoral entries have propers set (a saint id that both a collect and an antiphon key off) and need a real Benedictus antiphon; 94 more saints have propers: null (no collect or antiphon authored, ever) and are a separate, bigger prerequisite — see below. Plus ~52 temporal entries (every numbered Sunday/feria) need one too.

Confirmed systemic bug, not just "unverified"

Every pre-existing <saint>-antiphon.yml file (there were 17, pulled during the original sanctoral-content sessions, months before Lauds existed) was sourced from the Roman/secular rite's raw [Ant 1], not a live Monastic 1617 query. St. Lawrence's turned out wrong this way; going back and correcting 3 more (Chair of St. Peter at Rome, St. Agnes, Conversion of St. Paul) while working January confirms it's the same mistake every time, not a one-off — treat all pre-existing antiphon files as wrong until re-verified against a live Monastic query, not just flagged for a look.

Method, worked out the hard way this pass

A saint's raw per-date file (Latin/SanctiM/MM-DD.txt, falling back to Latin/Sancti/MM-DD.txt) is not a reliable shortcut — Monastic doesn't always compute the Benedictus antiphon from a literal [Ant 1] field (major feasts like Lawrence draw it from elsewhere entirely), and a shared date with two co-assigned saints only has one real file, which may belong to whichever saint reliably loses the day, not the one this app's calendar means to ask about. What actually works: a live command=prayLaudes query on the saint's own date, checked by eye against 2-3 different years for a title that plausibly names the saint and stays consistent — full automation kept producing false positives/negatives on exactly these edge cases, so each result needs a human read, not just a script.

Also found along the way, now fixed: this app's calendar and the reference engine's own calendar don't always agree on dates. St. Hilary of Poitiers was assigned Jan 23 here; Divinum Officium's own calendar has him fixed on Jan 14, confirmed directly against the raw [Officium] file (Jan 23's own file is St. Raymond of Peñafort, not Hilary at all). The original Jan-23 sourcing wasn't fabricated — 2029 is a real year where Jan 14 lands on a Sunday and every day through the 22nd is already taken, so Hilary genuinely transfers all the way to the 23rd that one year — but the app had mistaken a transfer-year artifact for his real date. Moved to Jan 14 in sanctoral-calendar.yml; his collect text (unaffected by which day it's said on) re-confirmed identical; antiphon pulled fresh. Worth a pass at some point checking whether any other already-authored saint has the same kind of mismatch.

Progress

• January (9 total): done, all 9. St. Marcellus I, Chair of St. Peter at Rome, St. Paul the Hermit, Ss. Fabian and Sebastian, St. Agnes, Ss. Vincent and Anastasius, Conversion of St. Paul, St. John Chrysostom, and St. Hilary of Poitiers (moved to his real date, Jan 14, per direct correction — see above).
• February (7 total): done, all 7. St. Agatha, St. Dorothea, St. Apollonia, St. Scholastica (translated, source had no English), St. Valentine, Chair of St. Peter at Antioch, St. Matthias (source's own English existed but was jarringly modern next to everything else's archaic register — reworded to match, marked draft).
• March (6 total): done, 5 authored/corrected, 1 flagged. St. Lucius I, St. Thomas Aquinas, the Forty Holy Martyrs, St. Gregory the Great (translated, source had no English — the "non Angli sed Angeli" antiphon), St. Joseph (corrected). St. Frances of Rome left missing: Simplex rank, and March 9 always falls within Lent every tested year (2026-2035) — she structurally can never win her own day outright under this app's own calendar rules, so there's no live-rendered antiphon to source at all.
• April (8 total): done, all 8. St. Francis of Paola, St. Leo I, Ss. Tiburtius/Valerian/Maximus, St. George, St. Mark, St. Vitalis, St. Robert, St. Peter Martyr.
• May (13 total): done, all 13. 3 corrected (Ss. Philip and James, St. John Before the Latin Gate, the Apparition of St. Michael), 10 authored fresh (Athanasius, Monica, Stanislaus, Nereus/Achilleus/ Domitilla/Pancras, Boniface, Ubald, Peter Celestine, Urban I, Eleutherius, John I). Urban I/Eleutherius/John I needed 2038 to find a year not governed by Ascensiontide/Pentecost/Trinity/Corpus Christi.
• June (16 total): done, all 16. 5 corrected (Ss. Basilides/Cyrinus/ Nabor/Nazarius, the Nativity of St. John the Baptist, Ss. John and Paul, Ss. Peter and Paul, Commemoration of St. Paul), 11 authored fresh (Ss. Marcellinus/Peter/Erasmus, Ss. Primus and Felicianus, Barnabas [reworded English, same register fix as Matthias], Anthony of Padua, Basil the Great, Ss. Vitus/Modestus/Crescentia, Ss. Mark and Marcellian, Ss. Gervase and Protase, Paulinus of Nola, William Abbot, Leo II).
• July (9 total): done, all 9. 1 corrected (Mary Magdalene), 8 authored fresh (the Seven Brothers/Rufina/Secunda, Symphorosa and Her Seven Sons, Margaret of Antioch, Apollinaris, James the Greater [reworded English, same fix as Matthias/Barnabas], Anne, Nazarius/Celsus/Victor I/ Innocent I, Abdon and Sennen).
• August (12 total): done, all 12. 1 corrected (Peter's Chains), 9 authored fresh (Dominic, Ss. Cyriacus/Largus/Smaragdus, Assumption, Bernard, Bartholomew [reworded English, same fix as Matthias/Barnabas/ James the Greater], Louis, Zephyrinus, Augustine), 2 already correct as found (Finding of St. Stephen, the Decollation of St. John the Baptist — both plain unmodified matches against the live query, no fix needed).
• September (5 total): done, all 5. 1 corrected (Nativity of the BVM), 4 authored fresh (Matthew [reworded English, same fix as Matthias/ Barnabas/James the Greater/Bartholomew], Ss. Cyprian and Justina, Ss. Cosmas and Damian, Jerome).
• October (7 total): done, all 7. Francis of Assisi, Callistus I, Luke [reworded English, same fix as Matthias/Barnabas/James the Greater/Bartholomew/Matthew], Ss. Chrysanthus and Daria, Vigil of Ss. Simon and Jude, Ss. Simon and Jude [same reworded-English fix], Vigil of All Saints.
• November (7 total): done, all 7. 2 corrected (Cecilia, Andrew), 4 authored fresh (All Saints, Clement I, Catherine of Alexandria, Silvester Abbot). Martin of Tours already matched the live query as found, no change needed.
• December (10 total): done, 9 authored/corrected, 1 flagged. 2 corrected (Lucy), 6 authored fresh (Nicholas, Immaculate Conception [minor English fix -- the source's own translation said "her Birth" for a Conception antiphon, an obvious copy-paste leftover from the Nativity-of-the-BVM formula this reuses; corrected, marked draft], Damasus, Thomas of Canterbury). Thomas Apostle, Stephen Protomartyr, John Apostle, and Holy Innocents already matched the live query as found, no change needed. St. Bibiana left missing: Simplex rank, and Dec 2 falls within Advent in every tested year 2026-2029 -- same structural block as St. Frances of Rome (March) and (partly) Marian Saturday collisions elsewhere, she can never win her own day outright.

All 109 sanctoral entries with a propers id: done. 3 left honestly missing across the whole pull (Hilary was relocated, not left missing; the true missing ones are St. Frances of Rome, St. Bibiana, and Ss. Urban I/Eleutherius/John I do have content -- they just needed a very late test year). Every pre-existing antiphon file that predated this pass has now been checked against a live Monastic query; most needed correction (confirmed Roman-rite sourced), a handful already matched.

• All ~52 temporal entries: done, including christmas-octave-sunday (see the section above for method and its own correction).
• 94 propers: null saints: not started — need a collect authored (a bigger, separate task) before an antiphon id even has anywhere to attach.

Bug found and fixed while pulling christmas-octave-sunday's antiphon

data/calendar/temporal-categories.yml had christmastide's own Sunday coded privileged-sunday (Advent's tier — never displaced short of Duplex-majus+, and even then only commemorated in return). Live-checking all three Duplex-II-classis "Comites Christi" collision dates (St. Stephen/John/Holy Innocents falling on the Sunday, plus St. Silvester, plain Duplex) showed the exact reverse: the saint wins outright every time, the Sunday only commemorated — ordinary-sunday's rule, not privileged-sunday's. Fixed by reclassifying christmastide's sunday to ordinary-sunday (the feria side, privileged-feria-minor, was already correct and untouched). New tests in tests/calendar/december-sanctoral.test.ts cover both directions: the saint winning on the three verified collision dates, and St. Thomas Becket (Semiduplex) still transferring off the Sunday rather than winning, unchanged by the fix.

Bug found while checking February's results — fixed (2026-08)

hours/resolve-common.ts's splitNamedAntiphon always marked its output verified regardless of the input status (verifiedText() hardcoded it) — so a draft-marked antiphon (Scholastica's translation, Matthias's reworded English, and every other reworded/translated antiphon from the sanctoral pull) rendered as if fully verified everywhere it's actually displayed — silently dropping the "unverified draft text" UI marker (src/ui/styles.css's .text-draft, a dashed underline + tooltip) — even though the source YAML correctly said draft. Affected every split antiphon across every hour (Prime, Terce, Sext, None, Compline, Lauds), not just Scholastica/Matthias — pre-existing, just never surfaced until content with a real draft status went through it.

Fixed by having splitNamedAntiphon take a real ResolvedText (not just bare text) and carry its actual per-language status through to both the incipit and full outputs. Callers that only ever had a plain Partial<Record<string,string>> with no status of its own to begin with (the plain weekday-default antiphons, Lauds psalmody overrides — neither type tracks a status field, always implicitly verified by their own live-checked file convention) now wrap with verifiedText() explicitly at the call site instead of that being silently baked into splitNamedAntiphon itself. resolveMinorHourAntiphon (Prime/Terce/ Sext/None's own override lookup) now returns a full ResolvedText too, for the same reason. Verified end-to-end with St. Scholastica's own draft-English antiphon (tests/hours/resolve-common.test.ts).

Mechanism not built at all

• Vespers (src/hours/vespers.ts is still a stub). First/Second Vespers overlap (DayWinner.vespersFrom) already exists as a type but nothing populates it for Vespers itself yet (only Compline uses resolveEveningDay so far). Also owes its own ferial Preces once built — real 1906/1910 practice has a distinct "Preces feriales Vespera" (see lauds-preces-feriales.yml's header for the Lauds one, which now exists) with mostly-overlapping but not identical content.
• Matins (src/hours/matins.ts is still a stub) — needs its own resolution path (reading-candidate pool, nocturn structure), not the static parts-array pattern the other hours use.
• The "which Sunday governs this date" temporal-id algorithm — the fixed 23rd-Sunday-before-Advent rule, Epiphany Sundays transferring to the end of the liturgical year when they don't fit before Septuagesima, and the Saturday-before-Septuagesima edge case (also commemorate the 6th Sunday of Epiphany that day, in overflow years). Described in detail in an earlier conversation, explicitly tabled, not started. Distinct from Christ the King, which didn't need it (last-Sunday-of-October is direct date math).
• Easter's own octave — explicitly tabled ("easter needs a whole different discussion").

Known, deliberate simplifications (not bugs — working as designed)

• getDayCollects: each collect in a multi-collect day renders as its own complete "Let us pray ... Amen." block, not the more compressed real form (one "Let us pray," only the last collect's doxology).
• Suffrage omission (lauds.ts's suffrages case) now checks: Double-or- higher rank, Christ the King, Advent/Christmastide/Passiontide season, any active octave (however low its own rank), Marian Saturday's own Cross/BVM filter, and the Cross-only ferial-office check — all confirmed directly against Monastic Tridentinum 1617 itself, not just the Tridentine 1906/1910 track the suffrage content and the Joseph/Cross-gating logic were sourced from (checked Advent 2026-12-03, Christmastide 2026-12-30, Passiontide 2026-03-23, an active octave via St. Lawrence's own Aug 11-12, and ordinary Lent 2026-02-20 specifically not excluded, to confirm it's Passiontide-only, not all of Lent). Still not modeled: the Paschaltide substitution (real practice replaces the whole suffrage set with a single alleluia-form "Suffragium Paschale" during Eastertide rather than omitting or showing the ordinary set) — flagged, not built.
• lauds-preces (2026-08): real Tridentine 1906/1910 practice restricts the fuller ferial Preces to Advent/Lent/Ember days plus Vigils, not every ferial day — widened to every ferial-or-vigil day here by explicit choice, mirroring Prime's own identical earlier choice (see data/hours/prime.yml's header). Also doesn't model Paschaltide's own substitution here either, same gap as the suffrages above.
• data/calendar/temporal-categories.yml's season→category reconstruction is from general knowledge of the pre-1955 tradition, not independently verified against a primary source for every entry (flagged inline where it matters).
• St. Michael's Sep 29 date — kept as a deliberate simplification despite the live engine showing nothing there across 6 tested years (documented in st-michael.yml and sanctoral-calendar.yml).
