Open work

A real backlog, not scattered code comments. Update this file when something here gets done, and add to it when new gaps turn up — don't let it drift back into "only findable by reading commit messages."

Priority

Work in this file follows one methodology, repeated every time a new hour or content type gets built: mechanism first, then a minimal live-verified proof (1-2 clean dates/entries authored fully, end-to-end) to confirm the mechanism is right, then bulk content authoring/import against the whole calendar once it's trusted. A section marked "mechanism built" but not yet "full sweep" or "all N done" is mid-pipeline, not stalled — its next work is more content in the same already-proven shape, not a design change. This file's dated build log (below "Open work, in priority order") is the record of that pipeline running across every hour and content type in this app.

Open work, in priority order

1. Mechanism gaps — a real design/code piece not built yet, blocking any content pass on it from starting:

   • (none currently open — the last one, Paschaltide's "Suffragium Paschale" substitution, was closed 2026-09-04, see the dated log below)

2. Minimal-proof-done, bulk content pending — mechanism is built and trusted (a proof date/entry already resolves correctly end-to-end); what's left is authoring/importing more content in that same shape across the rest of the calendar:

   • Matins Nocturn 2/3 responsory pools (both new, 2026-09-04 — see "Matins responsory pools: per-book expansion + new per-Common-category pool" below, and its own follow-up entry): the per-book pool now covers 11 of ~66 books (isa, gen, jer, exod, prov, sir, sap, tob, ezek, dan, 1macc); the new per-Common-category pool covers 19/19 real Commune categories (every category actually used by a saint except angel/evangelist/vigil, which have no Commune responsory file to source from) — this is the one that closes most of the 272-of-355 nocturn-readings files that had no responsory at all. Bible-plan TSV content also isn't yet in a test table (see "Bible-plan TSV — bulk conversion done" below).
   • Lauds/Vespers duplex-majus+ Common-category psalmody: all 24 SaintRecord.common categories are resolved (Vespers 10/10 real category files, Lauds 9/10 — see "Lauds/Vespers duplex-majus+ Common-category psalmody" below and its follow-up entry) with one genuine gap left: common-of-a-dedication's Lauds file specifically (Vespers' is done) — blocked on a real content gap, not a mechanism gap: its OT canticle ("Canticum Ieremiæ") has never been transcribed anywhere in this app (the 7 existing Lauds canticles, hours/lauds-canticles.ts, are only the plain weekday rotation) — needs sourcing before that one file can be authored without guessing.

3. New features (not content mechanism) — genuinely new product surface, not something a content pass is blocked on; each needs its own design pass, not just implementation:

   • Date picker: day-nav.ts currently only steps a day at a time (prev/next); there's no way to jump to an arbitrary date without walking there one day at a time or editing the URL. Needs a calendar-grid picker UI — open, not started.
   • Audio ("read it to me") interface: a button per hour/text that plays the office aloud instead of requiring reading — e.g. via the Web Speech API (SpeechSynthesis), which would keep this offline-first (no server-side TTS call, no added deploy dependency) but needs bilingual voice selection (La/En) worked out, and quality for Latin pronunciation is an open question. Open, not started — needs its own design pass before content/UI work begins.

4. Known, deliberate simplifications — intentional, not bugs, no plan to revisit unless priorities change:

   • temporal-categories.yml's bySeason mapping is fully live-verified (2026-09-01 sweep); what's still not independently re-verified is the privileged-period tier classification for a handful of specific stretches: Ash Wednesday and Holy Week are privileged-feria- major on strong prior knowledge, not directly re-checked; the Vigil of Christmas and Pentecost's own Ember days default to that same major tier as a guess pending verification; Pentecost's Ember days' actual precedence is flagged in-file as a genuinely unverified gap, not a guess dressed up as one (Lent's own Ember days are verified).

Everything from here down is the dated build log this priority list is drawn from — kept for the sourcing/verification detail behind each decision, not itself in priority order.

Content gaps — mechanism built, data incomplete

Lauds psalmody overrides + office-bundle overrides — done (2026-08)

Mechanism: src/hours/lauds-psalmody-overrides.ts, gated in hours/lauds.ts's getPsalmodyOverrideFor; office bundle (lauds-capitulum-/-responsory-/-hymn-/-versicle-<id>.yml in data/propers/common/) falls back to the plain weekday bundle independently of whether the psalmody override exists. Fires for a saint ranked duplex-majus or higher, or a named temporal feast (marian-saturday, christ-the-king, christmas-octave-sunday).

Authored — all 28 non-propers: null duplex-majus+ saints/temporal ids, plus the 4 already done going in (st-lawrence, marian-saturday, christ-the-king, christmas-octave-sunday) — full 32/32. Same methodology as the P/T/S/N batch: one live command=prayLaudes query per saint's own already-established clean date, Monastic Tridentinum 1617. Extraction automated this time via a purpose-built HTML parser (scratchpad/parse_lauds_html.py, not committed — a one-off tool, not application code) after manual grep/sed proved too slow at this volume; cross-validated against 5 saints' worth of already-known-correct content before trusting it for the rest, then spot-checked further plus an automated la==en/HTML-leftover sweep across all 28 outputs. Verified end-to-end with a runtime smoke test resolving each id's actual getLaudsPsalmodyOverride + all four bundle parts through the real mechanism, not just checking the YAML files exist.

The 5 antiphons cycle through a fixed pool matching the psalm scheme every one of these major feasts uses ("Psalmi Dominica"): psalms 92/99/62, the Canticle of the Three Young Men, then the Laudate group (Ps 148-150, one shared antiphon) — confirmed via the reference engine's own psalm-number labels, not assumed. This is the same 5-antiphon pool Prime/Terce/Sext/None draw from (Prime=group 1, Terce=2, Sext=3, None=5, skipping the canticle's own group 4) — real, confirmed structurally (see St. Scholastica below), not a coincidence.

St. Scholastica needed the same treatment as her P/T/S/N content: no English exists in the reference engine's data for her Lauds antiphons, capitulum, versicle, or hymn. Four of her five antiphons and her capitulum reuse the exact English already translated and verified for her Terce/Sext/None content (confirmed same Latin, since Lauds and the minor hours share this pool); the canticle antiphon, versicle, and 6-stanza hymn ("Jam noctis umbræ cóncidunt") are newly translated here. Real gap surfaced by this: the Lauds psalmody-override schema (hours/lauds.ts's BilingualText) has no per-language status field the way hours/resolve-common.ts's ResolvedText does — psalmParts unconditionally wraps every psalmody antiphon in verifiedText(), so her self-translated antiphon English can't carry the "draft" marker (.text-draft) the same content does at Prime/Terce/Sext/None. Flagged here, not fixed — would need BilingualText (or the override schema generally) to carry a status field through to psalmParts/resolvePsalmody.

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).

94 propers: null saints — collects authored (2026-08)

The reference engine's per-date Sancti//SanctiM/MM-DD.txt files are era-merged, not era-specific — blind extraction from them is unreliable. Live-querying (version=Monastic Tridentinum 1617) always resolved this correctly elsewhere in this project because the engine itself applies the right rubric filtering; reading a raw Sancti/MM-DD.txt file directly bypasses that filtering entirely. Those files accumulate centuries of saints assigned to the same calendar date across different eras, gated behind (rubrica ...)-tagged conditional blocks — reading the file's own untagged/default content silently returns whichever saint is currently primary there (often a post-1617, sometimes post-1888 addition), not necessarily the one relevant to this app's target era. Confirmed the hard way: an initial blind pull returned St. Didacus's collect for All Saints of the Benedictine Order, St. Rose of Lima's for Ss. Felix and Adauctus, St. Josaphat's for St. Martin I, and 9 more wrong matches out of 13 "clean, unambiguous" test cases — all real saints, just centuries later than 1617, and none of them what this app's own calendar actually intends for that date.

The fix: web/www/Tabulae/Kalendaria/ has real, era-specific calendar tables (not per-date files) — 1570.txt (Tridentine base) and M1617.txt (Monastic 1617's own diffs against it) — giving a direct, unambiguous answer for "which saint(s), what rank, commemorated with whom" on every date this app cares about, plus a fileref field (e.g. 01-15t, 08-23o, sometimes pointing at a wholly different MM-DD) identifying exactly which source file variant actually holds that entry's content — including cross-file (ex Sancti/05-08, Commune/C1v:Oratio 2 loco) and whole-file (@Sancti/05-08 as the file's own first line, no [Section] around it) inheritance, all resolved by a purpose-built parser (scratchpad/parse_kalendaria.py + extract_final.py, not committed — see the P/T/S/N and Lauds batches' own parser scripts for the established one-off-tool convention).

Cross-referencing all ~205 saints in data/calendar/saints/*.yml against this table (not just the 94) found the existing calendar data essentially sound — 204/205 confirmed correctly dated (only the deliberate example-confessor placeholder didn't match, as expected); the earlier wrong-saint problem was specific to this extraction method, not a systemic issue with the app's own calendar. No corrections to sanctoral-calendar.yml were needed.

Resolved St. Michael's own long-flagged uncertainty (st-michael.yml used to carry a "FLAGGED" comment about Sep 29 showing nothing live across 6 tested years): the table confirms Sep 29 genuinely is his day under Monastic 1617, rank 3 — it just never won outright in any tested year. His own source file is a whole-file cross-reference to the Apparition of St. Michael's (ex Sancti/05-08), confirmed word-for-word identical live — propers now points directly at apparition-of-st-michael's own id rather than duplicating content.

Two collect shapes, both now complete for all 94:

• 34 have a genuine proper collect — Latin pulled directly from source ({id}-collect.yml in data/propers/common/), English translated and marked status.en: draft for the ~11 where no source rendering exists at all (same convention as St. Scholastica's content earlier this session), verified/reused where the source does have one.
• 60 draw from a Common template — a real architectural addition, not a workaround: SaintRecord.collectCommon/collectName (calendar/feasts.ts) plus a substitution step in getDayCollect (hours/resolve-common.ts) fill a Common collect's literal {N} placeholder(s) with the saint's own name(s), positionally — most templates need one name, a few (two co-named saints sharing a collect, e.g. Ss. Cornelius and Cyprian) need two. 21 distinct Common-collect templates now exist (collect-c*.yml), named after the reference source's own C-numbering (C2, C2-1, C2a-1, C3b, etc.) rather than an invented semantic label, since no clean after-the-fact explanation was recoverable for why the tradition splits e.g. "Common of a Martyr Bishop" into five differently-worded variants. Each saint's own [Name] section supplies its declined form already in the exact grammatical case that saint's specific template needs (confirmed empirically — Ambrose's own [Name] is accusative, matching his template's own accusative {N} slot). One real wrinkle: Ss. Popes among the Martyr-Bishop groups (Cletus & Marcellinus, Soter & Caius, Anacletus, Anicetus) need the second, "(sed communi Summorum Pontificum)"-tagged declension in their own [Name] section, not the first — a real, source-documented distinction (Popes get their own template variant), not a parsing quirk to work around.

One genuine judgment call, flagged rather than silently resolved: St. Martha's own Monastic-specific source file (SanctiM/07-29.txt) overrides her base Tridentine assignment (collect-c6a, one name) with collect-c6b (two names) instead — a plural "Several Virgins and Martyrs" template that doesn't fit a single saint. Kept the singular collect-c6a assignment as the more sensible reading (see her own file's comment), treating the Monastic override as likely an inconsistency in that one file rather than a real joint-commemoration convention this app doesn't otherwise model.

Verified end-to-end: a runtime smoke test resolving getDayCollect for all 94 ids via a synthetic sanctoral-winner day, confirming a real (non-missing, no leftover {N}) collect for every one — not just that the YAML files parse.

94 propers: null saints — Benedictus antiphon + P/T/S/N Commons (2026-08)

The natural next step the collects batch unblocked. Two more real gaps found and fixed along the way, both explained below.

Raw Commune/*.txt fields don't reliably match what the engine actually renders per hour, same lesson as the collects pass but for antiphons this time. Commune/C2.txt's (Martyr-Bishop) own [Ant 1]/ [Ant 2]/[Ant 3] fields don't correspond 1:1 to Prime/Terce/Sext/None the way a naive reading would suggest, and no CommuneM/*.txt file defines explicit [Ant Prima]/[Ant Tertia]/[Ant Sexta]/[Ant Nona] fields for any of the categories this batch needed (only C10, BVM Saturday, has them). Confirmed independently: the already-authored common-of-a-confessor-bishop P/T/S/N content (from the original 29-saint pass) doesn't match Commune/C4.txt's own raw [Ant 1] either — it was live-query-sourced from Chair of St. Peter/St. Martin's own rendered pages, not read from the Commune file directly, which is exactly why. Fix: queried web/cgi-bin/horas/officium.pl directly (local Perl, not a network fetch — prayPrima/prayTertia/praySexta/ prayNona/prayLaudes, version=Monastic Tridentinum 1617) for one representative propers: null saint per Common category, parsing the antiphon (incipit + full, reconstructing the * split point) and chapter (citation, text, closing versicles) out of the rendered HTML — new scratchpad tool query_hours.py/batch_hours.py, not committed, same one-off-tool convention as the rest of this project's extraction scripts. Caught its own version of the collects batch's "wrong saint" bug this way too: St. Emerentiana's stored clean-year comment (2029-01-23) actually rendered St. Hilary of Poitiers's office by that year (a stale date after his own earlier Jan 23 → Jan 14 correction, see above) — every representative's title is now verified against an accent-insensitive name-stem match before its content is trusted, with a fallback year search when the stored date doesn't check out.

The real liturgical categories are coarser than SaintRecord.common's naming suggests — verified by cross-querying multiple saints per category, not assumed. common-of-a-martyr-bishop and common-of-a-martyr render byte-identical P/T/S/N and Benedictus antiphon content (confirmed: St. Anacletus, St. Simeon, St. Blaise, St. Pantaleon — four different collect-template variants, one shared minor- hour Common); so do common-of-an-abbot, common-of-a-confessor-not- bishop, and common-of-a-confessor (St. Odo, St. John Gualbert, St. Nicholas of Tolentino, St. Alexius); so do common-of-a-virgin-martyr, common-of-a-virgin, and common-of-a-holy-woman (St. Justina, St. Emerentiana, St. Praxedes, St. Martha). common-of-several-martyrs splits further than its own name suggests, though: plain groups of martyrs (Ss. Cornelius and Cyprian, Ss. Faustinus and Jovita, Ss. Placid and Companions — the last a real Duplex II. classis feast, not just a low-rank stub, confirming the fallback isn't only reached by minor saints) share one Common, but groups of Pope-martyrs (Ss. Cletus and Marcellinus, Ss. Soter and Caius) render distinct, more triumphal, allelúja-toned text of their own — a real category the collect templates already knew about (collect-c3b) that the common field alone doesn't surface. One saint, the Dedication of the Basilicas of Ss. Peter and Paul, turned out not to share its common field's nominal category (common-of-an-apostle) at all: live-verified its P/T/S/N and Benedictus antiphon are the Dedication-of-a-Church Common instead (about the building, matching its own collect-c8), not shared with any apostle content. Net result: 7 new shared Common categories (common-of-a-martyr, common-of-an-abbot, common-of-several- martyrs, common-of-pope-martyrs, common-of-a-vigil, common-of-a- virgin, common-of-a-dedication) plus the pre-existing common-of-a- confessor-bishop cover 66 of the 94 saints; the 7th confessor-bishop saint's own Benedictus antiphon Common file was also new (the original 29-saint pass never needed it — Chair of St. Peter/St. Martin both have their own proper Lauds antiphon, only their chapters were shared).

New mechanism: SaintRecord.benedictusCommon (calendar/feasts.ts) — getBenedictusAntiphon (hours/resolve-common.ts) now falls back to benedictus-antiphon-${benedictusCommon}.yml when a saint has neither a proper collect-antiphon pair nor... (see below) — deliberately no name- substitution mechanism built for it (unlike collectCommon): every Common category in current use renders name-free Benedictus-antiphon text; only the Doctor Common (C4a, not used by any saint here) has a {N}-shaped placeholder in the source.

Real bug found and fixed while wiring this in: getMinorHourOverrideId gated all Prime/Terce/Sext/None lookup — both the per-saint proper file and the shared-Common fallback — behind the same duplex-majus+ threshold Lauds' own psalmody override uses, on the assumption that only a strong feast carries its own minor-hour content at all. Live-querying this batch proved that wrong: a winning Semiduplex saint (St. Anacletus) still renders its own proper/Common antiphons at Prime/Terce/Sext/None, not the plain ferial default — the majus+ gate was only ever a proxy for "this app has authored proper content," not a real liturgical rule, and became actively wrong once Common-category content started covering lower ranks too. Fixed by making getMinorHourOverrideId eligible for any sanctoral winner; Lauds' own psalmody override (hours/lauds.ts's getPsalmodyOverrideFor) is unaffected and correctly stays majus+-gated, since that's a real, much bigger per-saint authored commitment (the whole psalm-antiphon block), not something this batch adds a Common fallback for.

One saint, Ss. Ursula and Companions, deliberately left without minorHoursCommon/benedictusCommon: her collect template (collect-c6b, plural Virgins and Martyrs) has no other member on this app's calendar to verify a shared minor-hour text against, and she can never be queried directly herself (a genuinely unwinnable stub, always commemorated under St. Hilarion) — left honestly unauthored rather than guessed from the singular common-of-a-virgin category, moot in practice since a commemoration's own minor hours are never rendered.

Verified end-to-end: a runtime smoke test (folded into tests/hours/resolve-common.test.ts) resolving getBenedictusAntiphon/ resolveMinorHourAntiphon/resolveMinorHourChapter for a sample across categories, including the Duplex II. classis case to confirm the majus+-gate fix isn't just a low-rank special case.

Not done in this pass: the other 26 of the 94 (propers now set to their own id, from the collects batch's proper-collect saints) still need their own individual Benedictus antiphon authored — same shape as the original 109-saint pass (own [Ant 1]/live-rendered text, not a shared Common), since a saint with a genuine proper collect usually has a genuine proper antiphon too. Not yet started.

The other 26 propers-set saints' Benedictus antiphons — done (2026-08)

Turned out most of these don't have unique antiphon text either — a genuine proper collect doesn't imply a genuine proper antiphon, same finding as St. Martin of Tours's mixed proper-antiphon/shared-chapter split from the original 29-saint pass. Live-queried Lauds (prayLaudes) for each of the 26, same title-verified method as the Common-category batch above.

15 of the 26 are genuinely unwinnable stubs (already documented as such from the collects pass — always commemorated, never the day's own title, so nothing to query) — same "honestly missing" treatment as St. Frances of Rome/St. Bibiana in the original 109-saint pass, not guessed at.

Of the 11 that do win outright, 7 turned out to share existing Common-category text — benedictusCommon wired directly to the already- authored files from the section above, no new content needed: Ss. Dionysius and Companions, Ss. Felix and Adauctus, Ss. Maurice and Companions, Ss. Tryphon and Companions (common-of-several-martyrs, despite Dionysius's own common field saying common-of-a-martyr- bishop — another case, like Chair of St. Peter earlier, where the two fields genuinely diverge), St. Chrysogonus and St. Donatus (common-of-a-martyr), the Vigil of St. Lawrence (common-of-a-vigil).

The remaining 4 have real, unique proper text — new {id}-antiphon.yml files: All Saints of the Benedictine Order ("Vos qui reliquístis ómnia..."), St. Agnes (secunda) ("Ecce, quod concupívi..."), St. Benedict ("Sanctíssime Conféssor Dómini..." — no English in the source, same gap as St. Scholastica's, translated and marked draft), and the Vigil of St. John the Baptist ("Eréxit nobis

• Dóminus cornu salútis..." — deliberately echoing the Benedictus canticle's own opening words, fitting for the Vigil of the saint whose father, Zechariah, first spoke that canticle).

P/T/S/N for these 26 not attempted in this pass — a further layer on top, same as how the original 109 got Benedictus antiphons long before their own later, separate P/T/S/N pass (duplex-majus+ subset only). Done in a later pass, see "minorHoursCommon gap swept across the whole calendar" below — it covers these 26 too, not just the original 109.

The 15 "unwinnable" stubs' Benedictus antiphons, resolved from source (2026-08)

Direct feedback on the section above: "unwinnable" was describing an artifact of Divinum Officium's own single-winner precedence model, not a real content gap — the app doesn't need a saint to win a live query to have real content, since this app already renders commemorated saints on their own terms (day.commemorations) rather than only ever showing the day's outright winner. The fix: read each of the 15 saints' own already-validated fileref directly (extract_final.py's load_file/resolve, the exact same fileref their collect was already sourced from during the Kalendaria-table pull — no live query, no "does this saint ever win" requirement at all) for its [Ant 1] section, falling back to whatever Common its own [Rule]/[Rank] "vide/ex CXX" reference names when there isn't one — the same proper-then-Common shape getDayCollect/collectCommon already uses, just applied to the Benedictus antiphon too.

14 of the 15 had no [Ant 1] of their own at all — clean Common fallback, and every one of their [Rule]/[Rank] C-numbers (C2a, C2a-1, C3, C3a, C3a-1, C4b, C6, C6-1, C6a, C7) falls inside a family already live-query-verified in the section above, so minorHoursCommon/benedictusCommon were wired directly with full confidence, no new content needed: St. Marcus (C4b — a whole-file @Commune/C4 inherit, just the title relabeled "of the Popes" — into common-of-a-confessor-bishop); St. Felix (Presbyter), St. Hermes, St. Saturninus (C2a/C2a-1 into common-of-a-martyr); St. Prisca, St. Thecla, St. Catherine of Siena (C6/C6-1/C6a into common-of-a-virgin); Ss. Machabees, Ss. Marius/Martha/Audifax/Abachum, Ss. Twelve Brothers, Ss. Alexander/Eventius/Theodulus/Juvenal, Ss. Felix/Simplicius/Faustinus/Beatrix, Ss. Nabor and Felix (C3/C3a/C3a-1 into common-of-several-martyrs). St. Felicitas is the one genuine new finding: her file points to C7 ("Commune Unius non Virginis Martyris"), which isn't a category this project had touched yet — but C7's own [Ant 1] is itself a cross-reference (@Commune/C6:Ant 2) that resolves to text byte-identical to common-of-a-virgin's own already-verified Benedictus antiphon, so no new Common file was needed even there.

The 1 remaining (Ss. Euphemia, Lucy, and Geminian) does have her own real [Ant 1] — but marked status.la: draft, not verified, on principle: a real counterexample turned up in the same pass while double-checking a winnable saint for comparison — St. Alexius's own file also has a genuine [Ant 1] ("Similábo eum..."), yet his actual live-rendered Benedictus antiphon (already confirmed in the section above) uses common-of-an-abbot's text instead, not his own [Ant 1] at all. So a raw [Ant 1] read is demonstrably not sufficient proof by itself that it's what the Benedictus canticle actually uses (Vespers' Magnificat is a live candidate for what it's actually for), even for a saint that can be live-checked — and for one that never can be, that uncertainty can't be resolved at all. Used the text anyway (better than nothing, and plausibly correct), just honestly flagged rather than claimed as confirmed.

All 15 now have real content — none left "honestly missing." Ss. Ursula and Companions (the section above) is the one case that's actually different in kind: no other calendar member shares her C6b/plural-Virgins-and-Martyrs category to cross-check a Common against, so even a clean file read wouldn't have anything solid to verify itself against.

A full sweep for the same pattern elsewhere, and 2 more real fixes (2026-08)

Same feedback, applied more broadly: swept every saint in data/calendar/saints/*.yml (not just the 94-batch's own lineage) for a still-missing collect or Benedictus antiphon, via a synthetic-winner smoke test. Found 4 hits; 2 were real, 2 were false positives from the sweep's own synthetic-day methodology (forcing a saint to be day.winner when in reality it's never the winner doesn't correctly exercise its real content path):

• St. Frances of Rome and St. Bibiana (Benedictus antiphon) — exactly the fix from the section above, just predating the Kalendaria-table work (no fileref had been derived for either yet). Both resolve to common-of-a-virgin once one is: Bibiana's file points to C6-1 directly; Frances of Rome's points to C7a (a whole-file inherit of C7, just the [Officium] title relabeled "of a Widow" — fitting, since she's a widow, not a virgin — with no override of the same [Ant 1] cross-reference, so it resolves identically).
• St. Agatha and St. Lucy (collect) — a real, older gap, from before collectCommon existed at all: both saints' own file comments already documented "no unique collect... resolves honestly missing... despite propers being set," written back when that was the only option. Agatha's own [Oratio] is @Commune/C6::s/N\./Agathæ/ — confirmed identical to the already-existing collect-c6.yml template — so collectCommon: collect-c6 was simply wired in. Lucy's own [Oratio] is @Commune/C7a, unedited (unlike collect-c6a.yml's own C7a-derived text, which has a "Vírginis tuæ" insertion baked in) — her own [Name] section supplies the whole descriptive phrase instead ("Lúciæ Vírginis et Mártyris tuæ", not just her bare name), making her resolved text effectively proper even though the underlying formula is a shared Common one; written as her own st-lucy-collect.yml (she already had propers: "st-lucy" set) rather than a new single-use collect-c7a template. No English [Oratio] in the source for either saint's own unedited form, so Lucy's stays status.en: draft.
• St. Clare (false positive) — the sweep's synthetic day forced her to be day.winner, but she never actually is one (always commemorated under St. Lawrence's octave); her real content lives in st-clare-commemoration.yml, used via a completely different code path (sanctoralCommemorationPart, not getBenedictusAntiphon) that the sweep doesn't exercise. Already fully authored and live-verified; no gap.
• Ss. Ursula and Companions (already covered above) — the one genuine, currently-irresolvable case.

Two vigils (Vigil of St. John the Baptist, Vigil of St. Lawrence) didn't resolve via this file-based method at all (their particular file format wasn't handled by this pass's parser) — no impact, both already had real content from the live-query batch above.

minorHoursCommon gap swept across the whole calendar (2026-08)

The pieces above all fixed Benedictus-antiphon/collect gaps. This pass does the same thing for Prime/Terce/Sext/None specifically, and widens scope from just the 94-saint batch to the whole calendar — the original 29-saint P/T/S/N pass (an earlier session) only ever covered duplex-majus+ saints; every below-majus saint from the original, pre-94-batch 109-saint pass had never had P/T/S/N attempted at all, same gap as the one already found and fixed for the 94-batch's own below-majus saints.

Method: reused the Kalendaria-table-validated fileref approach (same as the collects pass), not a blind Sancti/MM-DD.txt read — a real near-miss caught this early: St. Apollonia's Sancti/02-09.txt is currently St. Cyril of Alexandria's (a 19th-century addition to that filename slot); blind reading would have silently attributed his Doctor-of-the-Church Common to her. The Kalendaria table's own validated fileref (02-09o) gives her real content instead. Also fixed a second, unrelated regex bug the same pass turned up: the original "vide/ex CXX" pattern matched the bare word "Commune" (no number) and reading-specific sub-references like "ex C4 in 2 loco" (which only says where that nocturn's readings come from, not the overall antiphon Common) — found via St. Clement, whose Monastic-specific [Rule] override has neither a clean vide CXX nor a number after "Commune." Fixed by requiring a digit right after C and skipping any match immediately followed by "in N loco".

90 below-majus saints swept, ~82 wired directly into the categories already established above (mostly common-of-a-martyr and common-of-several-martyrs, the two largest families) — no new content needed, since every C-number variant found (C2/C2-1/C2a/C2a-1/ C2b/C2b-1/C2-1b, C3/C3a/C3a-1, C5/C5-1/C5a/C5b, C6/C6-1/C6a/C7a, C4/C4b, C1, C1v) already falls inside a family live-query-verified earlier.

A real bug this pass caught and fixed: Ss. Ursula and Companions (deliberately left minorHoursCommon-unwired, see her own section above) got swept up and wrongly wired to common-of-an-abbot by this pass's own script, since she has collectCommon set (making her look like a normal, resolvable batch member) despite propers: null and being a genuine commemoration-only stub — the underlying Kalendaria-table lookup silently defaulted to St. Hilarion's own primary slot at her shared date rather than her own (nonexistent) one. Caught by cross-checking every swept saint's propers field for this exact null-but-collectCommon-set pattern before trusting a default-to-primary assumption; reverted, she's still correctly unwired.

A real, new category found: Doctors of the Church are not one thing. 7 saints' own [Rule] says "vide C4a" (Commune Doctoris Pontificis) — but live-querying showed this doesn't mean what it looks like it means. St. Athanasius, St. Augustine, St. Basil the Great, St. Hilary of Poitiers, St. John Chrysostom, and St. Leo I all render P/T/S/N byte-identical to common-of-a-confessor-bishop's already-verified text (their own C4a reference just inherits C4's content underneath, per the same "the referenced file's raw fields don't reliably predict the live-rendered text" lesson from every other category this session) — wired directly, no new content. St. Gregory the Great is the one genuine exception: his own live-rendered P/T/S/N is real, unique proper text (alluding to his own election, his Liber Regulæ Pastoralis, the dove-and-quill legend, and the "non Angli sed Angeli" episode already known from his Benedictus antiphon) — 7 new files ({hour}-antiphon-st-gregory-the-great.yml, {terce,sext,none}-capitulum-st-gregory-the-great.yml), no minorHoursCommon needed at all (getMinorHourOverrideId already tries his own id first). English wasn't rendered at all for any of his 6 new texts (same Latin-duplicated-into-English gap as St. Scholastica/ St. Benedict), so all 6 are status.en: draft.

A loose thread noticed, then chased down and fixed (2026-08): St. Athanasius (May 2) and St. Leo I (April 11), both tested in years that happened to fall within Eastertide, rendered their shared common-of-a-confessor-bishop text with a trailing "allelúja" appended to every antiphon — but the other 4 Doctor saints (tested in non-Paschaltide months) didn't. Live-querying further (a full sweep of Common categories across the Easter/Ascension/Pentecost octaves and the ordinary weeks around them, reading the reference source's raw Commune/*p.txt chains directly rather than guessing from rendered pages) settled it precisely:

• A handful of categories (Apostles, Martyr, Martyr-Bishop, Several Martyrs, Pope-Martyrs) have their own dedicated Cxxp.txt source chain — a genuinely different text for Paschaltide, not the same text plus a suffix (confirmed by reading the raw files: e.g. the "Fíliæ Jerúsalem..." Pope-Martyrs Benedictus antiphon comes from a Matins responsory reused for Lauds specifically during this window, nowhere near the non-Paschaltide chain's own "Mártyrum chorus..." text). Only common-of-apostles has this wholesale text actually authored into this app's data (*-paschaltide.yml, from an earlier pass) — the other four still fall through to the mechanical suffix below until someone authors their real text, which is a strictly better approximation than the unmodified default.
• Every other category (Confessor-Bishop/Doctor, Abbot, Virgin, and presumably Dedication/Vigil/Angel, untested but structurally the same) has no dedicated chain at all — the reference engine just mechanically appends a single ", allelúja"/", alleluia" to the otherwise-unchanged base text, for the whole Eastertide → Ascensiontide → Pentecost-octave-week span. Live-verified across three unrelated categories (St. Athanasius/Confessor-Bishop, St. Robert/Abbot, St. Catherine of Siena/Virgin) — never doubled.
• The "sometimes 1, sometimes 2" appearance wasn't actually the same category flipping — it was different ranks of saint getting different octave privileges. Only martyr-class saints (already in the dedicated-chain group above) are ever eligible for even a commemoration inside a true privileged octave (confirmed: St. Anicetus, commemorated on a Semiduplex day inside the actual Easter octave, correctly showing the doubled dedicated-chain text). Confessor/Abbot/Virgin-class saints never get that far — checked St. Leo I and St. Basil the Great both landing on/near a real octave in some year, and both are fully transferred, no commemoration at all — so the plain-suffix categories structurally can never be observed inside a real octave, only in the ordinary weeks around it.
• One practical check this settled without needing a code change: common-of-pope-martyrs (Ss. Soter & Caius, Ss. Cletus & Marcellinus) is itself one of the dedicated-chain categories, so its one stored file is technically the Paschaltide-only text, not a universal default — but tracing both saints' fixed dates against every possible Easter date confirms this is harmless: whenever their date would fall outside Eastertide, it lands inside the Sacred Triduum instead (always fully transferred, never rendered), so the stored text is correct for every real occurrence.

Built: hours/resolve-common.ts's appendPaschaltideAlleluia/ withPaschaltideAlleluia, applied to the Common-category fallback branch of getBenedictusAntiphon and resolveMinorHourAntiphon (not the -paschaltide-file branch, which already had its own correct wholesale text; not a saint's own unique ${propers}-antiphon, which would need its own live-requery to confirm one way or the other rather than assuming the Common-category finding transfers; not capitula, whose closing versicles get the same suffix in the reference engine too — confirmed, St. Robert's Terce capitulum — but whose text is one embedded R./V. blob per language rather than a clean appendable tail, not attempted this pass). Guards against double-appending on a category whose stored text already ends in "allelúja" (common-of-pope-martyrs, per above). 4 new tests in tests/hours/resolve-common.test.ts (Paschaltide alleluia suffix on Common-category antiphons), 300 tests passing.

Verified end-to-end: a runtime smoke test (folded into tests/hours/resolve-common.test.ts) covering the same-person reuse case (Finding of St. Stephen → St. Stephen Protomartyr's own files), Gregory's unique content, and a shared-Doctor case, plus 8 more spot checks across the newly-wired families during the pass itself.

The last 2 duplex-majus+ P/T/S/N gaps, and a final-sweep bug (2026-08)

Closes out minorHoursCommon/P/T/S/N entirely: the original 29-saint pass held back 5 saints for lacking a collect at the time (st-benedict, all-saints-of-the-benedictine-order, st-michael, st-maurus-abbot, ss-placid-and-companions) — the latter two already got Common fallbacks wired in earlier sections above, and St. Michael redirects to Apparition of St. Michael's own content (see below). That left St. Benedict and All Saints of the Benedictine Order as the only two duplex-majus+ saints on the whole calendar with no P/T/S/N at all. Live-queried both the same way the original 29 were: real, unique proper text for each (Benedict's own Prime antiphon is the opening line of St. Gregory the Great's Life of St. Benedict; All Saints of the Benedictine Order draws on Matt 13:43, Luke 6:22-23, and a well-known All Saints antiphon) — 14 new files total, English translated throughout (status.en: draft) since the source rendered none for either saint's own texts.

A final calendar-wide sweep (every saint's resolveMinorHourAntiphon/ resolveMinorHourChapter, synthetic-winner methodology) turned up one more real gap: St. Michael himself. His propers field points at Apparition of St. Michael's own id (the two feasts are word-for-word identical, already established), and getDayCollect/ getBenedictusAntiphon both explicitly follow propers when looking up their own content — but getMinorHourOverrideId doesn't; it keys off the day's own winner id directly ("st-michael", not "apparition-of-st-michael"), so resolveMinorHourAntiphon was looking for a prime-antiphon-st-michael.yml that was never going to exist. Fixed the same way as Finding of St. Stephen: minorHoursCommon: apparition-of-st-michael on his own record, reusing his delegate's already-authored proper files directly. A real, narrow gap in the mechanism itself (not just missing data) — worth remembering if any other saint's propers ever points somewhere other than its own id.

Every real saint on this app's calendar now has real P/T/S/N content. The only remaining absence is Ss. Ursula and Companions (deliberately left unwired, no way to verify a category of one) and the example-confessor test placeholder, which was never meant to have any.

Christmas-Octave Sunday content — done (2026-08)

Was: only the Benedictus antiphon existed for christmas-octave-sunday (christmas-octave-sunday-benedictus-antiphon.yml) — no collect (a separate, older file, christmas-octave-sunday-collect.yml, did already exist and was untouched here), no Lauds psalmody override or office bundle, no Prime/Terce/Sext/None content at all.

Real code gap found and fixed along the way: getMinorHourOverrideId (hours/resolve-common.ts) only ever checked the sanctoral branch of resolveOfficeWinner's result — a named temporal feast in ALWAYS_OVERRIDE_TEMPORAL_IDS (marian-saturday, christ-the-king) got a Lauds psalmody override via getPsalmodyOverrideFor's own separate check of that set, but silently never a Prime/Terce/Sext/None one, however much content got authored for it — nothing had actually exercised that path until now. Fixed by mirroring getPsalmodyOverrideFor hours/lauds.ts's own temporal-id branch.

Content itself needed a different source than every other pull this session: Monastic Tridentinum 1617 has no real "Dominica Infra Octavam Nativitatis" identity of its own under its own calendar rules on most Dec 26-29 Sundays (verified live: 2026-12-27 renders as "S. Joannis Apostoli," not the Sunday, under version=Monastic Tridentinum 1617 — only the collect happens to be old enough to have been pulled from a date, 2029-12-30, where 1617 did render it outright). Lauds psalmody, office bundle, and Prime/Terce/Sext/None content instead pulled live under version=Divino Afflatu 1954 (2026-12-27), consistent with this app's own stated precedent of following D.A. for the calendar/precedence layer even while keeping Monastic 1617's shape for the hours themselves — this is one of the rare days where that split genuinely can't be maintained, since 1617 has nothing of its own to shape. christmas- octave-sunday-collect.yml's existing 1617-sourced text was kept as-is (cross-checked identical against both the new D.A. query and the raw Monastic Tridentinum 1617 source file, Tempora/Nat1-0.txt's own [Oratio]) rather than replaced.

Files: lauds-psalmody-overrides/christmas-octave-sunday.yml (3 psalms + Canticle of the Three Young Men + Laudate, all distinct antiphons), lauds-capitulum-/-versicle-/-hymn-christmas-octave-sunday.yml ("A solis ortus cardine"). No lauds-responsory-christmas-octave-sunday.yml authored — genuinely absent from the live rendering (hymn leads straight into the versicle, no short responsory in between), not an oversight; left "missing" honestly rather than invented. Prime/Terce/Sext/None all four get a proper antiphon (a short "Allelúia, ..." set drawn from the day psalter, distinct per hour); Terce/Sext/None each get a proper chapter (Gal 4:1-2/4:4-5/4:7, matching the raw 1617 source's own Nat1-0.txt exactly) with its own versicle per the D.A. live rendering (not the 1617 source's own versicle, which reuses one versicle across all three hours — a cross-era mismatch flagged here, not silently papered over, since this whole day's content already mixes eras out of necessity).

Not attempted: Nat2-0 (Feast of the Holy Name of Jesus) isn't in this app's sanctoral/temporal calendar at all yet — a separate, bigger ask if wanted (see the original scoping discussion this session).

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 — done (2026-08)

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.

Remaining gap, now closed (2026-08): resolveOfficeWinner deliberately only kicks in when temporalCategory === 'ordinary-feria' (the octave day has no standing of its own) — the live-verified counterexample was 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. Fixed by adding a kind === 'octave' branch to getDayCollects (gated on day.temporalCategory !== 'ordinary-feria', the same condition resolveOfficeWinner uses, so an ordinary octave day's already-rendered primary content never gets a redundant repeat), plus one new ${id}-octave-commemoration.yml proper file per octave for the four Christmas-stack ids (christmas-day, st-stephen-protomartyr, st-john-apostle, holy-innocents), sourced from each Sancti file's own [Octava 3] section in ../divinum-officium-reference (Second Vespers' own variant — the reference engine has three slightly different Octava 1/2/3 texts per octave, roughly Vespers I/Lauds/Vespers II, but this app's getDayCollects renders one shared block regardless of hour, matching the pre-existing "one Orémus per commemoration, not chained" simplification already noted above). The Holy Innocents' own English Octava 3 block turned out to carry a mismatched antiphon in the reference engine itself (the Common-of-Many-Martyrs "Isti sunt" text, not a translation of the Latin antiphon printed beside it) — worked around by sourcing the correct English from that same file's own [Ant 3]/ [Versum 3] sections instead (same Latin text, correctly paired translation) — see that file's own comment. Live-verified end-to-end via tests/hours/vespers.test.ts's 2033-12-30 stacking case (all four blocks resolve verified in both languages, not missing). This closes the octave-content gap listed at the top of this file's "Open work" section — no octave content work remains open.

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: done (2026-08) — see the dedicated section below for the collect-authoring pass and the era-specific- calendar discovery it took to do reliably. Benedictus antiphon: real content for all of them except the deliberate example-confessor test placeholder and Ss. Ursula and Companions (left honestly unset, no way to verify a category of one — see her own file's comment) — 66 via a shared Common (own dedicated section below); of the other 26 (own proper collect), 21 share an existing Common (7 live-query-verified directly, 14 more resolved straight from source once "unwinnable" stopped being treated as a content blocker — see that section's own note) and 5 have real unique text (one, Ss. Euphemia/Lucy/Geminian, honestly marked draft rather than verified since it can never be checked against a live rendering). P/T/S/N: done for all 94, and for the whole rest of the calendar besides — see "minorHoursCommon gap swept across the whole calendar" and "The last 2 duplex-majus+ P/T/S/N gaps" below; every real saint on this app's calendar has real P/T/S/N content now except Ss. Ursula and Companions, same reason as above.

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 ordo — built (2026-08): src/hours/vespers.ts now resolves a full ordo (opening versicle, weekday/seasonal psalmody with the 115+116 join and 138 split, chapter/responsory/hymn/versicle bundle with Advent/Lent/Passiontide/Paschaltide overrides, Magnificat with weekday- default antiphon fallback, day-collects) off resolveEveningDay, so First/Second Vespers precedence and the cross-day commemoration (commemorationOf — "the loser is commemorated unless the loser is simplex", live-verified) both apply before any part runs. See data/hours/vespers.yml's header and tests/hours/vespers.test.ts.

• Vespers cross-day commemoration now labeled, and feast-side privilege now has a mechanism (2026-08-26): a cross-day commemoration (Commemoration's vespersNote: 'today' | 'tomorrow', set only by calendar/vespers.ts's two commemorationOfDisplaced* functions) now renders as "(of today)"/"(of tomorrow)" in English, "de præcedenti"/"de sequenti" in Latin (calendar/day-label.ts) — the real Divino Afflatu phrasing, per horascommon.pl. Also added forbidsSuccessorCommemoration to both SaintRecord (calendar/feasts.ts) and TemporalFeastRecord (calendar/temporal-feasts.ts) — the feast-side mirror of the day-side privilege calendar/commemorations.ts already modeled (a privileged Sunday/major-feria can refuse a weak commemoration back; nothing previously let a high-ranked feast refuse to commemorate forward at its own kept Second Vespers). Deliberately a flag, not a ported rank-threshold formula (the reference engine's own version is a messy fractional-rank matrix) — set only after checking a specific date against the live engine, same convention as vigilOf.

  • The concrete case that motivated this: Most Precious Blood (July 1, Duplex I classis) vs. the Feast of the Sacred Heart (Easter + 68 days), which only ever fall adjacent in a very-late-Easter year (Easter in late April). Read the Perl variables carefully (initial pass here got this backwards): it's Sacred Heart's own kept Second Vespers that refuses to commemorate Precious Blood the next evening ("Vespera de præcedenti; nihil de sequenti", $winner = Sacred Heart/Pent02-5 = today at that point in the branch, $cwinner = Precious Blood/07-01 = tomorrow), not the reverse. The other direction — Precious Blood's own Vespers commemorating a Sacred Heart that happens to fall the day after it, the other rare late-Easter arrangement — has no matching carve-out in the reference engine at all, so forbidsSuccessorCommemoration is deliberately set only on sacred-heart.yml, not most-precious-blood.yml.
  • Still open, separately: the reverse gap remains in daytime decideOccurrence (calendar/commemorations.ts) — a sanctoral winner there unconditionally gets its displaced Sunday/feria commemorated back, regardless of the winner's own rank. Not addressed here; this pass only covered the Vespers cross-day direction.

• Ascension, Corpus Christi, and the Feast of the Sacred Heart now modeled as real temporal feasts (2026-08-26): none of the three had a TemporalFeastRecord at all — only referenced as bare date offsets in easter-offsets.yml/temporal-categories.yml/ isMajorFixedFeastOfTheLord. Corpus Christi/Sacred Heart's own days were already blocked from any sanctoral winner (privileged-feria- major), but with no record, resolveTemporalId fell back to whatever Sunday collect governs that week (post-pentecost-01 for both), so the day displayed as generic Trinity-week feria content, never "Corpus Christi"/"Sacred Heart" by name. Ascension (Easter+39) was worse: ascensiontide's own temporal-categories.yml entry is plain ordinary-feria for every day in the season including Ascension Thursday itself, so nothing stopped an ordinary sanctoral candidate from winning that day outright had one ever been scheduled there. All three now have data/calendar/temporal-feasts/{ascension,corpus- christi,sacred-heart}.yml (rank: duplex-1-classis, an easter anchor, octave: {enabled: true, wins: duplex}) — the pre-1955 calendar specifically (each carries a real octave; the reference engine's own "(rubrica 196)"-tagged variant strips it, later-reform text this project doesn't follow, per CLAUDE.md). Sacred Heart's own record also carries forbidsSuccessorCommemoration (see the previous entry above) — the live-sourced Precious Blood exclusion this whole pass started from.

  • octave.wins: duplex is matched to pentecost-sunday.yml's own verified threshold as the closest analogue for all three, and was kept despite a known, direct counter-example already in this codebase: tests/hours/vespers.test.ts's St. Ubald case was previously live-verified against Divinum Officium (Monastic Tridentinum 1617) to have him — Semiduplex — win First Vespers within Ascension's own octave window, which a strict duplex threshold contradicts. Real octaves come in three privilege "orders"; Ascension/Sacred Heart are the weakest (Order III), historically permissive enough for an ordinary Semiduplex saint to still occur inside them, unlike Pentecost's own (Order I) octave this threshold is borrowed from. Kept at duplex anyway per direct instruction — the Ubald test (and St. Margaret of Scotland's equivalent First Vespers case, inside Corpus Christi's own window) were updated to assert the new behavior instead of the old live-verified one. Revisit if this turns out to misfire elsewhere; see ascension.yml's own comment for the full note.
  • No propers content (collects/antiphons/hymns/lessons) authored yet for any of the three — this pass is calendar/occurrence mechanics only, same "content vs. mechanism" split as everywhere else in this file; an hour resolving one of these ids will correctly show status: 'missing' text until that's authored.

Matins ordo — mechanism built, small content slice (2026-08)

src/hours/matins.ts was the last stub hour. Built as a genuinely different shape from every other hour: no static data/hours/matins.yml parts list — the ordo is assembled programmatically per day, since the real structure (1 nocturn on a plain ferial day, 3 on a Sunday or Duplex-and-higher feast, with a variable number of readings) doesn't fit the static-array pattern every other hour uses.

Explicit, direct-instruction departures from the historical office (see memory vu-not-a-reconstruction/vu-matins-design — this app was never meant to reconstruct any one historical form, Matins least of all):

• Nocturn 1 is always the user's own continuous scripture-reading plan (src/propers/bible-plan.ts, sourced from a personal TSV outside this repo), never the historical per-day lectionary — a variable number of readings per day, and deliberately not the Rule of Benedict's own "summer" reading contraction (Low Sunday–1st Sunday of November): this app reads in full year-round, live-confirmed the reference engine's own Monastic 1617 data does apply that contraction (monastic.pl's brevis_monastic/legend_monastic) before deciding not to reproduce it.
• Recombine, don't reproduce the historical lesson split: where the source splits one continuous work across several numbered lessons purely to fill a fixed lesson-count slot, this app joins them into one reading (src/propers/octave-readings.ts's resolvePassages, now reused outside the octave-day store it was built for — extended via the new src/propers/nocturn-readings.ts). Split only kept where the underlying source genuinely changes (e.g. a Gospel pericope vs. the homily on it).
• Nocturn 3 gated at Duplex-and-higher, plus every Sunday unconditionally — the user's own chosen threshold (real Monastic 1617 is more permissive), reusing the already-existing isDoubleOrHigher (which already means rank ≥ duplex, so no new rank helper was needed).
• Generous multi-source reading inclusion, not winner-takes-all: every commemorated saint (not just the office winner) and every active octave contributes its own Nocturn 2/3 reading when authored — mirrors getDayCollects's existing "one collect per commemoration" pattern, applied to readings. Wired src/propers/octave-readings.ts's getOctaveReading into a real caller for the first time — it had zero callers anywhere in the codebase before this, clearly built ahead of Matins and left unwired until now.
• Gospel sourcing has exactly two allowed sources: the user's own plan (flagged via isGospel, book-derived — confirmed the user's plan never assigns one on a Sunday, a deliberate editorial choice, not a gap) and the day's own genuine proper Gospel+homily. A Common-of-Saints fallback Gospel is never used — nocturn-readings.ts has no Common-fallback mechanism at all (unlike collectCommon/ benedictusCommon elsewhere), so the exclusion falls out of the store's own shape rather than needing special-case code.
• Invitatory (Ps 94) framed like an ordinary antiphoned psalm — one opening (incipit-or-full), one full repeat after — not the historical interspersed-refrain shape (confirmed live: real practice repeats the antiphon between every verse group). Direct instruction, not an oversight.
• Responsories matched loosely by scriptural book, not exact citation — per the user's own description of how they actually worked historically. New seeded pool, data/hours/matins-responsories-by-book.yml + src/propers/matins-responsories.ts (currently just isa, from a live Advent-ferial query — a real seed, not a full pool).

Sunday's fixed 12-psalm/3-canticle psalmody (data/hours/matins-sunday- antiphons.yml) — Nocturn 1 = Ps 20-21/22-23/24-25, Nocturn 2 = Ps 26-27/28-29/30-31 (Rule of Benedict ch. 18's own arrangement, distinct from Roman Matins' 9-psalm Sunday scheme), Nocturn 3 = 3 OT canticles (Isa 33:2-10, Isa 33:13-18, Sir 36:14-19) under one shared antiphon. Transcribed from the reference engine's own Monastic-labeled block (Psalterium/Psalmi/ Psalmi matutinum.txt's [Daym0]), then live-verified end-to-end (command=prayMatutinum, 2026-09-06) — psalm numbers, canticle citations, and the 12-lesson/Te Deum sequence all matched exactly. Real gap found along the way: the reference engine's own UI flags Monastic 1617 Matins as "still incomplete and under construction" — the pieces actually queried checked out regardless, but worth remembering if a future pull comes back looking wrong.

Real content authored for two clean proof dates (one per branch, per this project's usual "mechanism first, minimal live-verified proof, content later" build order):

• Ferial: 2026-12-15 (Tuesday of Advent III) — the user's own plan's "Isa 36-37, Wis 14" (citation-only for now; full Vulgate/Douay-Rheims import is a deferred separate project, see below), matched against the seeded Isaiah responsory pool.
• Sunday: 2026-09-06 ("14th Sunday after Trinity", post-pentecost-15 — the Trinity-counted display label and the Pentecost-offset storage id are a fixed, already-computed one-off relationship, not something new built here) — Nocturn 1 from the user's plan ("Tob 1-2, Sir 45", citation-only), Nocturn 2 a real, fully-translated patristic reading (St. Gregory the Great, Moralia in Job, Bk. 9 — live-transcribed, both languages), Nocturn 3 the day's own proper Gospel (Luke 7:11-16, the raising of the widow's son at Naim) plus St. Augustine's homily on it (Sermon 44), also fully transcribed. Real seam flagged, not papered over: this Sunday's real historical Nocturn 1 is the Book of Job (confirmed live) — Nocturn 2's Job commentary is kept as-is even though this app's own Nocturn 1 no longer reads Job that week, since it's real, valuable, season-proper patristic content, not tied to any specific saint.
• Two Isaiah chapters actually populated in src/data/scripture/ (33, live-transcribed for the Sunday canticles) — small, real progress against the eventual bulk Bible import, not just placeholders.

Verified end-to-end: tests/hours/matins.test.ts, both branches, resolving real dates through the actual resolveOrdo mechanism (psalm/canticle counts, Te Deum presence, reading citations and statuses, Gospel flagging and its Common-fallback exclusion, responsory matching) — not just checking the YAML files exist. npm test (359 tests) and npm run build both pass.

Reading-pool redesign — done (2026-08)

Corrected a miscommunication in the original mechanism build above: readings are now pool-assembled, not fixed-slotted. Every source that can contribute for a day — the office winner, every commemorated saint, a transferred-in feast (already folded into day.winner by resolveDay, no separate lookup needed), every active octave, the plain temporal id, and the user's own scripture-plan reading — is gathered into one ordered pool (buildReadingPool in src/hours/matins.ts), then sliced into however many nocturns the day's psalmody has (distributeIntoNocturns, ceiling division, pool order preserved). No reading kind is pinned to a specific nocturn anymore — scripture is no longer reserved for Nocturn 1, patristic content no longer reserved for Nocturns 2-3.

The 1-vs-3-nocturn psalmody gate (Duplex+/Sunday) is unchanged — it governs psalm/canticle/ Te Deum structure only. It no longer limits which days get patristic content authored or shown: a sub-Duplex ferial day's single nocturn now pools in patristic/hagiographic content whenever it's been sourced, alongside the scripture-plan reading — direct instruction, "we want patristic readings for every saint where we can source one, not just duplex+."

src/propers/bible-plan.ts's getBiblePlanReadings is now dual-keyed: most rows still key off (temporalId, weekday), but the source TSV's Dec 25 - Jan 13 stretch keys off a fixed MM-DD calendar date instead (read straight through regardless of which temporal Sunday governs the day) — a date can match both keys at once (e.g. a Sunday after Epiphany landing inside Jan 1-13), and both are pooled rather than one overriding the other. No calendar-date rows are authored yet (mechanism only); see memory vu-matins-design for the full design writeup. npm test (359 tests, unchanged — the two proof dates still resolve the same content, just via the new pool/distribute path) and npm run build both pass.

Not done in this pass — explicitly deferred, not silently dropped:

• Full Sunday/feast-calendar patristic-reading authoring — now framed as "every saint where a reading can be sourced," not just the ~75 Duplex+ saints that get their own Nocturn 3 slot (see the reading-pool redesign above: content is no longer rank-gated, only nocturn count is). Update (2026-08): the post-Pentecost season side of this is now done — see "Temporal-cycle nocturn-readings sweep" below.
• The per-book responsory pool beyond its one seeded book (isa).
• The bulk Vulgate (Latin) + Douay-Rheims (English) import into src/data/scripture/ — in scope for the project long-term, explicitly deferred past this pass per direct instruction.

Temporal-cycle nocturn-readings sweep — post-Pentecost season done (2026-08)

The user noticed 2026-08-23's Matins (a plain Sunday, post-pentecost-13) was missing its Nocturn 2/3 patristic reading entirely. Root cause: post-pentecost-15 (above) was the only temporal id with any nocturn-readings content authored — every other ordinary Sunday/week across the whole year had none, a gap distinct from (and larger than) the sanctoral-saint gaps tracked elsewhere in this file.

Scope turned out bounded: calendar/temporal-id.ts's resolveTemporalId maps every day in a liturgical week (Sunday and its ferias alike) to the same id, and hours/matins.ts's buildReadingPool already keys nocturn-readings lookup by that shared id — so one file per temporal id covers its entire week, not one file per date. Authored all 23 remaining post-pentecost-NN ids (01-14, 16-24; -15 already existed) from the reference engine's own Tempora/PentNN-0.txt (Latin) / English/Tempora/PentNN-0.txt files:

• post-pentecost-01 (Trinity Sunday, Duplex I classis): has its own full 9-lesson proper office, unlike every other Sunday in the season — Nocturn 2 (St. Fulgentius on the Trinity) plus two separate Nocturn 3 readings (St. Gregory Nazianzen's homily on Matt 28, and a distinct "Commemoratio Dominicæ" — St. Augustine's homily for the displaced First Sunday after Pentecost's own Gospel, Luke 6:36-42, which the Duplex I classis feast bumps into a commemoration rather than dropping — consistent with this project's generous-commemorations principle).
• post-pentecost-02 through -11: each has real, unique proper content for both Nocturn 2 (a patristic/theological excerpt, one continuous author per week — St. John Chrysostom, St. Augustine, Pius XI, St. Ambrose, St. Jerome, St. Gregory the Great, etc.) and Nocturn 3 (that week's own Gospel pericope + homily). -11 is the last week in the source with its own proper Nocturn 2; every week after it has Nocturn 3 only.
• post-pentecost-12 through -14, -16 through -24: Nocturn 3 only (no proper Nocturn 2 in the source from here on — the historical Nocturn 1/2 for these weeks is a continuous Old Testament book reading with commentary that isn't written out per-Sunday in the static files the way the Gospel+homily slot is; sourcing that properly would need live-CGI queries per date, out of scope for this pass, left as a known gap rather than guessed at). Every week's Lectio7 in the source is a bare "Et réliqua" Gospel incipit, not a full pericope — per this project's standing convention, not authored as its own Gospel reading; only the homily (Lectio7's own opening paragraph plus Lectio8-9, one continuous work) is authored, isGospel: false.
• Responsory reuse discovered and followed: the source itself cross-references the same two responsories for the Nocturn 2 and Nocturn 3 homily slots in nearly every week (@Tempora/Pent01-2:ResponsoryN for Nocturn 2, @Tempora/Pent01-0:Responsory8 — "Duo Séraphim" — for the Nocturn 3 homily), rather than a fresh responsory each week. Resolved those cross-references once (from Pent01-2/Pent01-3/Pent01-0) and reused the resulting text verbatim across every file that points at them, rather than re-deriving per week.
• A genuine authoring bug found and fixed mid-pass: three of the first Nocturn-3-only files (post-pentecost-13, -14, -16) initially omitted the homily's own opening paragraph — it lives inside the source's [Lectio7] section (right after the bare Gospel incipit), not [Lectio8], and an early extraction pass started from Lectio8 by mistake. Caught by re-diffing each file's opening sentence against the source before moving on; fixed by prepending the missing paragraph (Latin + English) to all three. Worth remembering for any future pass over this same source shape: always check that a Nocturn 3 homily reading's first sentence matches Lectio7's own prose, not Lectio8's.

Live-verified via npx tsc --noEmit, npm test (452 tests, up from 447 — 5 new cases in tests/hours/matins.test.ts's new "post-Pentecost season nocturn-readings sweep" describe block, including a spot-check of 2026-08-23 itself), and npm run build. No fixture collisions from this pass (pure content addition under already-existing ids, no calendar changes).

Not done in this pass — explicitly deferred, not silently dropped:

• The rest of the temporal cycle: Advent (advent-1..4), Christmastide (christmas-octave-sunday), post-Epiphany (post-epiphany-1..6), Septuagesima through Lent (septuagesima, sexagesima, quinquagesima, lent-1..4), Passiontide/Holy Week (passion-sunday, palm-sunday), and Eastertide (easter-sunday, easter-octave, easter-3..6, sunday-after-ascension, pentecost-sunday) — same shape of gap, same pipeline, just not yet worked through season by season.
• Sourcing real Nocturn 2 content for post-pentecost-12 onward via the Pentecost-offset id itself — resolved differently, not left open, see "Calendar-month/week nocturn-readings import" immediately below: that content turned out to be keyed by civil calendar month, not Pentecost offset, at the source, so it needed a second id scheme, not a live-CGI lookup.
• Ferial-specific (non-Sunday) content within a post-Pentecost week — not applicable here, since the whole week already shares one temporal id/file by design (see above); flagged only so a future reader doesn't go looking for post-pentecost-13-tuesday.yml-style files that were never meant to exist.

Temporal-cycle nocturn-readings sweep — rest of the year done (2026-08)

Extended the post-Pentecost sweep above to the other 26 temporal ids — Advent (advent-1..4), christmas-octave-sunday, post-Epiphany (post-epiphany-1..6), Septuagesima through Lent (septuagesima, sexagesima, quinquagesima, lent-1..4), Passiontide/Holy Week (passion-sunday, palm-sunday), and Eastertide (easter-octave, easter-3..6, sunday-after-ascension) — using the reference engine's own per-season Tempora files (Adv1-0.txt..Adv4-0.txt, Nat1-0.txt, Epi1-0a.txt/Epi2-0.txt..Epi6-0.txt, Quadp1-0.txt..Quadp3-0.txt, Quad1-0.txt..Quad6-0.txt, Pasc0-0.txt..Pasc7-0.txt). 24 of 26 ids got real, sourced Nocturn 2/3 content on the first pass; the remaining 2 temporal ids in this season range (easter-sunday, pentecost-sunday) were initially misdiagnosed as genuine source gaps (see below) — corrected the same day, both now authored too.

• post-epiphany-1's real source is Epi1-0a.txt, not Epi1-0.txt: the reference engine reassigns Epi1-0.txt to the later (1893/1921) feast of the Holy Family, which this project doesn't model (see the temporal-cycle survey note on Holy Family as a still-open pre-1955 gap, elsewhere in this file). Epi1-0b.txt (a thin Dominica I post Epiphaniam wrapper cross-referencing Epi1-0a for its own Nocturn 1) confirmed Epi1-0a.txt carries the real older "Dominica infra Octavam Epiphaniæ" office underneath. That file also has a real structural gap of its own: its [Rule] reads "Initia cum responsory" and it carries no [Responsory4]-[Responsory9] tags at all — its Nocturn 2/3 responsories come from a continuous weekly "Historia" cycle not transcribed per-Sunday in the static files (same class of gap as the post-Pentecost season's un-sourced Nocturn 2 weeks). post-epiphany-1.yml's two readings are authored without a responsory field for this reason, not with an invented one.
• sunday-after-ascension's source file (Pasc6-0.txt) has no responsories of its own either (only [Responsory8], proper to a single lesson) — its own [Rank]/[Rule] say "ex Tempora/Pasc5-4" (Ascension Thursday itself), meaning the whole office, responsories included, is inherited from that day. Resolved by pulling the representative responsories directly from Pasc5-4.txt rather than leaving them unauthored.
• easter-sunday (Pasc0-0.txt) and pentecost-sunday (Pasc7-0.txt) were initially (wrongly) called source-level gaps, then corrected same day. Both files' own [Rule] really does read "1 nocturn" (their whole night office collapses to 3 lessons, straight to Te Deum) — true, and unlike every other Sunday in this sweep. But "1 nocturn instead of 3" is not the same claim as "no Nocturn 2/3 content exists": Lectio1 in both files opens with a bare Gospel incipit ("Et réliqua") immediately followed by a full patristic homily (Easter: Pope St. Gregory the Great, Homily 21 on the Gospels, on Mark 16:1-7; Pentecost: the same, Homily 30, on John 14:23-31) continuing through Lectio2-3 — real, substantial, translatable content, just compressed into one nocturn rather than split across three the way an ordinary Sunday's 9 lessons are. hours/matins.ts already supports single-nocturn source content tagged nocturn: 1 (the Ember days' own nocturn-readings files do exactly this), and this app's own threeNocturns rule (every Sunday renders 3 nocturns regardless of the historical rubric for this particular feast) reslots the pool across 3 rendered nocturns anyway — the nocturn: 1 tag only affects pool-ordering relative to other same-day contributors, not final placement. Authored easter-sunday.yml/pentecost-sunday.yml the same way as every other Nocturn-3-style entry in this sweep: incipit dropped, Lectio1's homily portion combined with Lectio2-3 into one reading, Responsory1 (the only nocturn-proper responsory transcribed in either source — Responsory3 doesn't exist, the office runs straight to the Te Deum after Responsory2's Gloria repeat).
• Cross-reference reuse continues the post-Pentecost pattern: several Sundays' [Responsory4]/[Responsory7] tags are themselves cross-references to a different file (e.g. post-epiphany-3 through -6 all point back to post-epiphany-2's own Responsory4/7; easter-6 points back to easter-5's Pasc4-0 responsories) rather than fresh text — resolved and transcribed directly, same as before, not left as unresolved pointers.
• The "homily begins inside Lectio7 itself" pattern, not just at Lectio8, held for nearly every Sunday in this pass (not only the few post-Pentecost weeks that showed it) — every file's Nocturn 3 combines Lectio7's homily portion (dropping only the bare Gospel incipit) with Lectio8-9, using Lectio7's own responsory to represent the combined reading.

Live-verified via npx tsc --noEmit, npm run build, and npm test (806 tests, up from 777 — a "rest-of-year temporal nocturn-readings sweep" describe block in tests/hours/matins.test.ts covering all 28 ids end-to-end, easter-sunday/pentecost-sunday included; two pre-existing tests in the ferial-branch describe block also needed a small filter update, since Advent I's own ferial dates now legitimately pool in advent-1.yml's patristic content alongside the user's bible-plan readings). No fixture collisions (pure content addition under already-existing ids, no calendar changes) except one real interaction the new content surfaced: 2026-02-23, initially picked as a lent-1 proof date, turned out to actually be the Vigil of St. Matthias transferred onto that Sunday and winning outright — swapped for 2031-03-03, a clean lent-1 date.

Temporal-cycle nocturn-readings sweep, all 52 ids, is now fully complete — no remaining gaps. The lesson from the easter-sunday/pentecost-sunday misdiagnosis: "the source's own [Rule] says 1 nocturn" is a claim about nocturn count, not about whether content exists — always check whether [Lectio1]-[Lectio3] (or whichever lessons exist) carry real prose before calling a short nocturn structure a content gap.

Calendar-month/week nocturn-readings import — done (2026-08)

Follow-up to the post-Pentecost sweep above: the user asked about the "Nocturn 3 only, from post-pentecost-12 onward" gap it left open, correctly guessing that the reference engine's real Nocturn 2 content for those later Sundays lives in older, month-labeled files rather than being genuinely absent.

Confirmed: Tempora/08N-0.txt through 11N-0.txt (N = 1-5, August-November, ~20 files) — the old "Scriptura occurrens" reading cycle, "Dominica I-V Augusti/Septembris/Octobris/Novembris." Each has [Lectio1]-[Lectio3] (Nocturn 1 scripture — not imported, the user's own bible-plan store already owns that slot) and [Lectio4]-[Lectio6] (Nocturn 2 patristic commentary — the actual target).

The real complication, and why this needed a mechanism addition, not just content files: which month-week file governs a given Sunday is not a fixed post-pentecost-NN correspondence — it's computed straight from the civil calendar (first Sunday of each month, with irregularities), and shifts every year with Easter's date. Ported the reference engine's own Date.pm::monthday() sub faithfully into src/calendar/month-week-id.ts (monthWeekId), using this app's pre-1955/Tridentine rubric baseline (Date.pm's own $modernstyle = false): no 1960-rubric October week-III vanishing (skipped entirely, since that whole adjustment is modernstyle-gated); November's backward-from-Advent renumbering for week > 0 does still apply (that part of the source isn't modernstyle-gated). Live-verified against the localhost CGI instance across 3 different years (2026, 2027, 2028) including the August 1st-falls-on-a- Saturday skip case and November's real week-II-vanishes case (2026: Nov 1/8/15/22 render "I. /III./IV./V. Novembris" — II is genuinely skipped that year, matching the ported algorithm exactly).

Wired in as a third, independent pooling source in hours/matins.ts's nocturnReadingIds/buildReadingPool — month-week-<id> (e.g. month-week-081), pooled alongside (not replacing) the ordinary temporalId-keyed lookup, same dual-key precedent as propers/bible-plan.ts's Dec25-Jan13 calendar-date stretch. All 20 ids authored as data/propers/nocturn-readings/month-week-<MMN>.yml; each file's 3 lessons are one continuous work (recombined per the standing rule), so one NocturnReading per file. month-week-092 turned out to cite the exact same Moralia-in-Job passage already authored for post-pentecost-15 — reused that existing translation rather than re-transcribing it.

Live-verified via npx tsc --noEmit, npm test (460 tests, up from 452 — a new "calendar- month/week nocturn-readings import" describe block in tests/hours/matins.test.ts spanning 2026-2028 to prove the date-driven lookup, not a hardcoded id), and npm run build. No fixture collisions (pure content + one new pooling source, no calendar changes).

Not done in this pass: the same month-week treatment for whatever Sundays this pass didn't reach (there are none within Aug-Nov — all 20 files are authored); the rest of the temporal cycle (Advent through Eastertide, per the post-Pentecost sweep's own "not done" list above) remains open and is unrelated to this particular gap.

Ordering bug found and fixed same day: pooling a temporalId's own file (Nocturn 3 only, for a late post-Pentecost Sunday) alongside a separately-sourced month-week-<id> file (Nocturn 2 only) put the Nocturn 3 reading ahead of the Nocturn 2 reading in the pool — the two sources were being concatenated in nocturnReadingIds set order, not grouped by each reading's own nocturn tag, so distributeIntoNocturns's front-light positional slotting (1st pool reading -> Nocturn 1, 2nd -> Nocturn 2, rest -> Nocturn 3) put the Nocturn-3-tagged reading into the Nocturn 2 slot and vice versa. Confirmed live on the date that surfaced the whole month-week gap in the first place (2026-08-23, post-pentecost-13 + month-week-084): St. Gregory's Moralia commentary (tagged nocturn: 2) was showing up after St. Augustine's homily (tagged nocturn: 3) instead of before it. Fixed in buildReadingPool (hours/matins.ts) by bucketing every contributing id's readings by reading.nocturn and emitting the buckets in ascending numeric order — not hardcoded to [2, 3], since Ember days' own nocturn-readings files use nocturn: 1 for their single-nocturn structure, and an initial [2, 3]-only version of this fix silently dropped those (caught by tests/calendar/ember-days.test.ts failing). Within each bucket, id order (and each file's own reading order) is preserved, matching this pool's usual priority rule. npm test green at 460 tests — no fixture changes needed, since every previously-authored id's own file already had its readings correctly ordered internally; only the cross-source case this pass introduced was actually broken.

Nocturn-readings responsory marker fix — done (2026-08-23)

Every data/propers/nocturn-readings/*.yml responsory with a responsory: field (53 files: all 24 post-pentecost-*, all 20 month-week-*, the 6 Ember-day files, plus st-monica, st-marcellus-i, apparition-of-st-michael) started straight into the Latin/English text with no leading marker, unlike data/propers/octave-readings/*.yml's own convention of an explicit ℟./℣. at the start of each line. User flagged this via the Augustine reading on 2026-08-23's date and explicitly chose to fix it in content, not by injecting a marker at render time. Given each file already uses plain V./R. (not the ℣./℟. glyphs) for the versicle and the mid-responsory repeat, R. was prepended to just the opening la/en text of each responsory to match that same plain-letter convention already used internally by these same files — not a switch to octave-readings' Unicode-glyph convention, which remains a separate, still-open reconciliation between the two stores if it's ever wanted. Mechanical, scripted edit (53 files, idempotent — skips any responsory already starting R. ), verified no unexpected format by having the script flag anything it couldn't parse (none found). npm test (460), tsc, and npm run build all still green — pure content edit, no code/mechanism change.

Pre-1955-but-post-1617 saints' Matins readings — done (2026-08)

Resolved the former "mechanism gap" above into a concrete, scoped content pass — no new mechanism was actually needed, since nocturn-readings.ts/buildReadingPool already accept content from any source once authored (see the reading-pool redesign above); this was a sourcing gap, not a design gap.

Method: read the reference engine's own files directly on disk (../divinum-officium-reference), not live queries — web/www/horas/Latin/Sancti/MM-DD.txt is the Tridentine track (Sancti, no M), web/www/horas/Latin/SanctiM/MM-DD*.txt the Monastic track. A saint with a Sancti/ file but no SanctiM/ file at all (any suffix) never existed in Monastic 1617, confirming the pre-1955-but-post-1617 case. Critical wrinkle found and now memory'd (see memory vu-reference-engine-file-layout, vu-matins-pre1955-saints): the plain, unsuffixed Sancti/MM-DD.txt is very often the wrong saint — the general/Tridentine calendar keeps piling later canonizations onto the same date slot in that file, displacing the older saint into a suffixed sibling file (01-23o.txt, 03-04cc.txt, etc.) or, in one case (St. Paul the Hermit), an entirely different date. Every one of the ~52 candidates was individually verified by [Officium] match, not assumed from the filename.

Scope, computed against sanctoral-calendar.yml's 204 saint-day entries: 52 pre-1955-only candidates (Sancti/ present, no SanctiM/ at all, any suffix); of these, 43 had real proper lesson content to author, 9 turned out to be pure Common-of-X with no proper text in the source at all (st-lucius-i, vigil-of-st-james, st-christina, vigil-of-st-bartholomew, ss-twelve-brothers, vigil-of-ss-simon-and-jude, st-saturninus, st-sabbas, vigil-of-st-thomas — correctly left unauthored, not a gap). All 43 authored as src/data/propers/nocturn-readings/<id>.yml, same shape and combine-where-sensible rule as the two original proof dates. A few readings reuse already-verified text from post-pentecost-15.yml where the source file itself cross-references another day's lessons (e.g. st-monica's Nocturn 3 Gospel, the same Luke 7:11-16 pericope). A handful of bare Gospel pericopes were left unauthored where the source gives only an incipit ("Et réliqua") and no full text was available to transcribe (flagged per-file, not silently dropped) — same deferral as the bulk Vulgate/Douay-Rheims import. One saint (st-anicetus) has an English-source transcription bug (Latin duplicated under the English heading) — this project's own translation used instead, marked draft.

npm test (365 tests, all passing — none of the new saints are in a test table yet, same as the bible-plan bulk conversion) and npm run build/tsc --noEmit both pass.

Not done in this pass: the larger pool of saints that do have a Monastic 1617 (SanctiM/) track — same authoring shape, separate/older backlog item (see priority §2 above).

SanctiM (Monastic 1617)-track saints' Matins readings — done, all 12 months (2026-08)

The complementary pool to the pre-1955 pass above: saints with a SanctiM/MM-DD*.txt file. Method finding, worth recording: a SanctiM/MM-DD.txt file almost always turns out to be a thin rule override (@Sancti/MM-DD plus tweaks to psalmody/lesson-count/antiphons), not independent content — when it doesn't override the Nocturn 2/3 [LectioN] sections, that saint's Monastic-office vita reading is the same text as the Tridentine Sancti/MM-DD.txt file, sourced exactly as in the pre-1955 pass above. Only a real Monastic-only saint (one with no Sancti/MM-DD*.txt at all, e.g. st-maurus-abbot, who isn't on the general Tridentine calendar) needs content read directly out of the SanctiM/ file itself.

A second wrinkle, on top of the pre-1955 pass's "don't trust the plain file" one: the "does a SanctiM/MM-DD*.txt exist for this date" scope check has to be done per saint, not per date — a shared calendar date (two ids mapped to the same MM-DD) can have a SanctiM file for one saint's own Tridentine slot while the other saint has no Monastic office at all. Naively globbing "any SanctiM/MM-DD*.txt exists for this date" over-counts: found this by hand for Jan 18 (chair-of-st-peter-at-rome has SanctiM/01-18.txt; st-prisca, sharing the date, does not — she was actually a missed pre-1955-pool candidate) and Jan 14 (st-hilary-of-poitiers has SanctiM/01-14.txt; st-felix-presbyter, sharing the date via Sancti/01-14cc.txt, does not — likewise a missed pre-1955-pool candidate). Both were authored this pass using the pre-1955 pattern instead. The 52/117 pre-1955/SanctiM split recorded above is therefore an undercount on the pre-1955 side by at least these two; the true per-saint (not per-date) recomputation used for this pass found 152 ids with a genuine, correctly-suffix-matched SanctiM file — see memory vu-matins-pre1955-saints for the running correction note.

A third finding: a Sancti/SanctiM date landing inside the Christmas or Epiphany octave (e.g. st-telesphorus Jan 5, st-hyginus Jan 11 — both early popes commemorated on octave days) can have its entire Nocturn 2/3 given over to octave-of-the-season homiletic content (a Nativity/Epiphany sermon), with no proper vita text for the saint at all in either track. Correctly left unauthored for these two — not a gap, same category as the pre-1955 pass's 9 pure-Common exceptions, just a different underlying reason (octave-absorbed, not Common-of-X).

January done (11 saints, 2 left unauthored per the octave finding above): st-hilary-of-poitiers, st-felix-presbyter, st-maurus-abbot (Monastic-only; no English source translation exists in the reference engine at all for this file, so en is this project's own translation, marked draft), st-anthony-abbot, chair-of-st-peter-at-rome (Nocturn 2 patristic + Nocturn 3 genuine Gospel-and-homily, both authored), st-prisca, ss-fabian-and-sebastian, st-agnes, ss-vincent-and-anastasius, conversion-of-st-paul, st-john-chrysostom. st-telesphorus, st-hyginus (octave-absorbed, see above) were originally left unauthored here — since authored, see "Octave-absorbed and Vigil-only readings" below. npm test/tsc --noEmit both pass; none of these are in a test table yet, same as the pre-1955 pass.

February done (8 saints, 1 left unauthored as Common-only, 1 vigil left unauthored as Common-only): st-ignatius-of-antioch (Nocturn 2 patristic vita + Nocturn 3 homily-only, bare Gospel incipit not transcribed per convention), st-agatha, st-dorothea (turned out to be a missed pre-1955-pool candidate, not a real SanctiM case — the SanctiM file for this date belongs to St. Titus, who shares Feb 6 and isn't on vu's own calendar), st-romuald, st-scholastica, st-simeon (also a missed pre-1955-pool candidate — the SanctiM file at this date is unrelated content for St. Bernadette Soubirous, not Simeon), chair-of-st-peter-at-antioch (Nocturn 2 patristic + Nocturn 3 homily-only), st-matthias (Nocturn 3 homily-only; Nocturn 2's own Lectio4-6 falls back to Common of an Apostle, not proper text). Left unauthored: st-valentine (Lectio93 itself is @Commune/C2:Lectio4 — Common-only, no proper text in the source at all) and vigil-of-st-matthias (Vigilia rank, ex C1v, no Lectio content at all — Common-only). npm test/tsc --noEmit both pass.

A fourth SanctiM-pass finding, from this month: a bare Gospel incipit ("Et réliqua") with a genuine patristic homily following it (st-ignatius-of-antioch's Nocturn 3, chair-of-st-peter-at-antioch's Nocturn 3, st-matthias's Nocturn 3) is now authored as the homily alone, isGospel: false, not combined with the bare incipit line and not marked isGospel: true — cleaner than chair-of-st-peter-at-rome's January file, which included the incipit line under isGospel: true despite not having the full pericope text. That January file is left as-is (not wrong, just an earlier, less clean judgment call) — this convention applies going forward.

March done (6/6 saints): st-thomas-aquinas, st-frances-of-rome, forty-holy-martyrs, st-gregory-the-great (Lectio7-9's Gospel+homily is generic Chair-of-Peter content copied verbatim into this file, unrelated to Gregory — same lessons as chair-of-st-peter-at-rome.yml's own sourcing, not proper to this feast, so not authored here), st-joseph, st-benedict (Duplex I class patronal feast — the richest SanctiM case yet: Nocturn 2 sourced from Sancti/03-21.txt's own vita per the usual pattern, but Nocturn 3 is genuinely Monastic-only content not found in Sancti/ at all — a St. Peter Damian sermon preached specifically for Benedict's own feast; no English/SanctiM/03-21.txt exists in the reference engine, so en for that reading is this project's own translation, marked draft). npm test/tsc --noEmit both pass.

April done (9/9 saints): st-leo-i, ss-tiburtius-valerian-and-maximus (missed pre-1955-pool candidate — the date's only SanctiM file belongs to St. Justin, who shares Apr 14 and isn't sourced this way), st-george (a reference-engine data bug: Sancti/04-23.txt's own [Lectio94] Latin section actually contains English prose — same kind of bug as st-anicetus in the pre-1955 pass — so la here is this project's own translation, marked draft; en is the source text, genuinely present just filed under the wrong heading, verified), st-mark, ss-cletus-and-marcellinus, st-vitalis, st-robert (genuinely Monastic-only, no Sancti/04-29*.txt at all; no English source translation exists either, so en is this project's own translation, draft), st-catherine-of-siena and st-peter-martyr (a newly found date-swap wrinkle: this app's calendar has Catherine on Apr 29 and Peter Martyr on Apr 30, the opposite of the general Tridentine calendar's own Apr 29/Apr 30 pair — both sourced from their real, off-date Tridentine files, the same off-date pattern as St. Paul the Hermit in the pre-1955 pass; Peter Martyr in particular has no genuine SanctiM match at either date, so also a missed pre-1955-pool candidate). npm test/tsc --noEmit both pass.

May done (12/13 saints, 1 left unauthored as Common-only): ss-philip-and-james (Nocturn 3 has a full Gospel pericope, John 14:1-13, not a bare incipit — the first case since chair-of-st-peter-at-rome in January where isGospel: true was actually warranted), st-athanasius, ss-alexander-eventius-theodulus-and-juvenal (missed pre-1955-pool candidate — SanctiM's own suffix-matched file just narrows the joint feast, same pattern as ss-vincent-and-anastasius/ss-cletus-and-marcellinus), st-john-before-the-latin-gate, st-gregory-nazianzen, ss-nereus-achilleus-domitilla-and-pancras, st-boniface (missed pre-1955-pool candidate — the date's only SanctiM file is a different, later saint), st-ubald (same), st-peter-celestine, st-pudentiana (missed pre-1955-pool candidate — shares its date with Peter Celestine, whose SanctiM file the naive per-date check matched instead), st-urban-i and st-john-i (both missed pre-1955-pool candidates via the "plain file is the wrong, later saint" wrinkle). Left unauthored: st-romanus-abbot — turns out to have a real SanctiM/05-22M.txt file after all (resolving the earlier "neither file" mystery from the pre-1955 pass), but it carries no Lectio content at all, only vide C5b (Common of a Confessor) — Common-only, not a gap. npm test/tsc --noEmit both pass.

June done (12/13 saints, 1 left unauthored as no-proper-content): ss-marcellinus-peter-and-erasmus, ss-primus-and-felicianus, st-barnabas, st-basil-the-great, ss-vitus-modestus-and-crescentia, ss-mark-and-marcellian (missed pre-1955-pool candidate), nativity-of-st-john-the-baptist, st-william-abbot (a genuine Monastic-only vita exists too, but its content is essentially identical to the Tridentine track's own account and only the Tridentine track has an English translation, so sourced from there instead), ss-john-and-paul, st-leo-ii (off-date, like St. Paul the Hermit in the pre-1955 pass — the general calendar keeps him on Jul 3, not Jun 28), ss-peter-and-paul (Duplex I class), commemoration-of-st-paul. vigil-of-st-john-the-baptist was originally left unauthored here as "only a Nocturn 1, no content" — wrong: Lectio1-3 turned out to be real homiletic content, just filling the Vigil's simpler single-nocturn slot; since authored, see "Octave-absorbed and Vigil-only readings" below. npm test/tsc --noEmit both pass.

July done (13/18 saints, 5 left unauthored as Common-only): ss-seven-brothers-rufina-and-secunda, st-pius-i, st-john-gualbert, st-anacletus, st-alexius, ss-symphorosa-and-seven-sons (the last four missed pre-1955-pool candidates — see the ninth finding below), st-bonaventure (a reference-engine translation-misalignment bug — its English section boundaries don't line up with the Latin, so en here is this project's own translation, draft), st-mary-magdalene, st-apollinaris, st-james-the-greater, st-anne, st-martha, ss-abdon-and-sennen. Left unauthored (Common-only, no proper text at all in the source): ss-nabor-and-felix, st-margaret-of-antioch, st-liborius, st-christopher, ss-felix-simplicius-faustinus-and-beatrix. npm test/tsc --noEmit both pass.

A ninth finding, from July: the Monastic calendar keeps a full Octave of St. Benedict (Jul 11-18, since his own feast is Mar 21 but his Monastic-only "Transitus" observance sits in July) — every SanctiM file at these dates that isn't a saint's own real match turns out to be "Nth day within the Octave of St. Benedict" content, not a genuine candidate mismatch to puzzle over. Recognize this pattern (In Octava S. P. N. Benedicti Abbatis) and move on quickly rather than re-investigating it saint by saint.

August done (13/16 saints, 3 left unauthored as no-proper-content): st-peter-ad-vincula, ss-machabees (missed pre-1955-pool candidate), st-stephen-i (missed pre-1955-pool, "plain file is a different, later saint" trap), st-dominic, ss-cyriacus-largus-and-smaragdus, st-clare (missed pre-1955-pool candidate), st-lawrence (Duplex I class), st-bernard, st-bartholomew, st-augustine, decollation-of-st-john-baptist, st-sabina (missed pre-1955-pool candidate), and assumption — the Duplex I class feast of the B.V.M. itself, confirming this app's calendar does map the Assumption despite the parent CLAUDE.md's older note that fixed BVM/Lord feasts were "not modeled by this app at all yet"; Nocturn 1's own scripture (Song of Songs) left to the bible-plan store per this project's usual split, only Nocturn 2/3 patristic/Gospel content authored here. Left unauthored (no proper content at all in the source, same category as prior Common-only/Vigil exceptions): ss-nabor-and-felix-style st-romanus and st-hermes (both Common-only). vigil-of-st-lawrence was originally left unauthored here as "Nocturn 1 only, no content" — wrong, same correction as vigil-of-st-john-the-baptist; since authored, see "Octave-absorbed and Vigil-only readings" below. npm test/tsc --noEmit both pass.

September done (9/9 saints, full month): nativity-bvm, st-hadrian (missed pre-1955-pool candidate), st-matthew, ss-maurice-and-companions (missed pre-1955-pool), st-linus, st-thecla (missed pre-1955-pool), ss-cosmas-and-damian, st-michael (Dedication of St. Michael the Archangel — its SanctiM file structurally borrows from his own separate May 8 Apparition file but the actual Lectio content resolves back to this day's own Sancti file), st-jerome. npm test/tsc --noEmit both pass.

October done (9/13 saints, 4 left unauthored as Common-only or no-content): st-remigius, st-francis, ss-placid-and-companions, st-marcus (missed pre-1955-pool candidate), st-callistus, st-luke, st-hilarion, ss-chrysanthus-and-daria, ss-simon-and-jude. Left unauthored: st-justina and st-gall (both genuinely Monastic-only — no Sancti/ file at all — but their own SanctiM files are themselves Common-only, vide C6/vide C5b, no proper Lectio content to source), ss-ursula-and-companions (Common-only, no proper content — matches this file's own earlier flag in the "individually-flagged content gaps" section), and vigil-of-all-saints (re-checked per "Octave-absorbed and Vigil-only readings" below: its Lectio1-3 are genuinely a bare @Commune/C3:Lectio7-9 in 2 loco rubric, not real content like the other two vigils below turned out to be — correctly still unauthored). npm test/tsc --noEmit both pass.

November done (14/16 saints, 2 left unauthored as Common-only): all-saints, st-martin-of-tours, st-menna (missed pre-1955-pool), st-martin-i (off-date, like St. Paul the Hermit — general calendar keeps him Nov 12, this app's own Nov 12 goes to St. Emilian), all-saints-of-the-benedictine-order (genuinely Monastic-only, and unusually one of the few such cases with both rich content and an available English translation), dedication-of-the-basilicas-of-ss-peter-and-paul (missed pre-1955-pool; one sentence of the source's own English translation was left untranslated, so en for that reading is draft), st-pontian (missed pre-1955-pool), st-cecilia, st-clement, st-felicitas (missed pre-1955-pool), st-chrysogonus (missed pre-1955-pool), st-silvester-abbot, st-peter-of-alexandria (missed pre-1955-pool), st-andrew. Left unauthored (Common-only, no proper text at all in the source): st-emilian, st-odo — both genuinely Monastic-only but with no Lectio content in their own SanctiM files, the same wrinkle as st-justina/st-gall in October. npm test/tsc --noEmit both pass.

December done (13/15 saints, 2 left unauthored as Common-only) — final month, pass complete: st-bibiana, st-nicholas, st-ambrose, immaculate-conception (two genuinely distinct Nocturn 2 sources kept as separate readings — St. Jerome's sermon, and the Acts of Pius IX defining the dogma in 1854), st-damasus, st-lucy, st-thomas-apostle, st-stephen-protomartyr, st-john-apostle, holy-innocents, st-thomas-becket, st-silvester-i, st-eusebius-of-vercelli (off-date, missed pre-1955-pool candidate — vu places him Dec 15 via Monastic 1617's own same-day redirect, but his real proper content is at the general Tridentine calendar's Dec 16; no SanctiM file exists for him at either date). Left unauthored (Common-only, no proper text at all in the source): st-barbara (correct file Sancti/12-04o.txt) and st-melchiades (correct file Sancti/12-10o.txt — this also corrects an earlier wrong "neither Sancti nor SanctiM file" claim about him in memory vu-matins-pre1955-saints, the same "verify by opening the file, not just checking existence" lesson as November's St. Romanus Abbot correction). Adding st-eusebius-of-vercelli's content surfaced a 3rd Matins lesson on the fixed Advent III Tuesday proof date (tests/hours/ matins.test.ts, Dec 15 falls under his commemoration) — updated that test's expected lesson count from 2 to 3, not a regression: exactly the "commemorations get their own reading" design working as intended once real content exists to surface. npm test (365 tests) and tsc --noEmit both pass.

Pass complete: all 12 months (January-December) of the SanctiM-track saints' Matins readings are now done — 133 saints authored across the whole year, the rest correctly left unauthored as Common-only/no-content cases. See memory vu-matins-sanctim-saints for the full per-month record and the twelve method findings this pass turned up.

Octave-absorbed and Vigil-only readings — corrected policy, 4 saints authored (2026-08)

Direct instruction, correcting this pass's own earlier judgment call: "octave-absorbed" (the day's Nocturn 2/3 given over to a Nativity/Epiphany homily instead of the saint's own vita) and "Vigil, Nocturn 1 only" were both being treated as "no content, correctly left unauthored" — wrong. This app pools readings first and figures out how/where to display them later (see hours/matins.ts's own buildReadingPool header); real, sourceable text at a saint's own calendar slot should go into that pool even when it isn't proper to that particular saint, rather than being withheld because it came from "a different rubric variant." Four saints previously left unauthored for these two reasons are now authored, flagged in each file's own header as not-proper-to-the-saint:

• st-telesphorus (Jan 5) — St. Augustine's Christmas-octave sermon (Nocturn 2) + St. Jerome's homily on Matt 2:19-23 (Nocturn 3), neither proper to Telesphorus himself.
• st-hyginus (Jan 11) — St. Fulgentius's Epiphany sermon (Nocturn 2) + St. Ambrose's homily on Matt 2:1-12 (Nocturn 3), neither proper to Hyginus himself.
• vigil-of-st-john-the-baptist (Jun 23) — St. Ambrose's homily on Zachary and Elisabeth (Luke 1:5-17), authored from Lectio1-3, the Vigil's own single 3-lesson nocturn (not the usual Lectio4-9 Nocturn 2/3 slot a full feast uses).
• vigil-of-st-lawrence (Aug 9) — Pope St. Gregory the Great's homily on self-denial (Matt 16:24-27), same Lectio1-3 single-nocturn source.

vigil-of-all-saints (Oct 31) was re-checked under this same corrected policy and confirmed still genuinely contentless — its Lectio1-3 are a bare @Commune/C3:Lectio7-9 in 2 loco rubric with no proper text at all, unlike the two Vigils above. Not every "left unauthored" case from this pass needs revisiting — only the octave-absorbed and Vigil-only categories were affected by this policy correction; genuine Common-only cases (a bare @Commune rubric with no Lectio text anywhere) are unaffected and remain correctly unauthored.

Adding these introduced no new lesson-count regressions in tests/hours/matins.test.ts (none of its fixed proof dates fall on Jan 5/11 or Jun 23/Aug 9). npm test (365 tests) and tsc --noEmit both pass.

Octave-readings audit — two real gaps found and closed, scope of the rest recorded (2026-08-28)

Prompted by the user pointing out that the reference source keys octave-day content by calendar date (e.g. 08-11oct.txt through 08-16oct.txt for St. Lawrence's octave), not grouped by octave-day-number the way data/propers/octave-readings/<feast>-octave-day-N.yml is — a genuinely different question from the saint-level sweep above, not covered by it. Audited every fixed-date octave (st-lawrence, assumption, all-saints, immaculate-conception, nativity-bvm) for missing days: most gaps in the existing files (IC days 4/6, Nativity-BVM day 7, Lawrence days 6/7) turned out to be days where the source's own [Rank] says vide Sancti/ MM-08 with no Lectio override at all — genuinely no distinct content to author, matching the existing precedent already set by St. Lawrence's own correctly-unauthored days. Two, however, were real gaps with genuine, un-authored Lectio content:

• immaculate-conception-octave-day-8.yml (Dec 15, the octave's own closing/"In Octava" day) — Pope Pius IX's dogmatic bull (a different excerpt than any other day in the octave) + a homily of St. Epiphanius of Salamis on the BVM (Lectio7-9, bare Gospel incipit dropped per the usual rule). Both languages present and verified in the source.
• nativity-bvm-octave-day-3.yml (Sep 10) — St. Jerome's homily on Matthew's genealogy (Matt 1:1-17, bare incipit dropped). No usable English exists in the reference engine for this file — English/Sancti/09-10bmv.txt is a verbatim Latin duplicate, the same reference-engine data-bug class as st-anicetus/st-george — so en is this project's own translation, draft.

Both live-resolved correctly (resolveOrdo on 2026-12-15 and 2026-09-10) and tsc --noEmit/ npm test (522 tests) both pass.

Christmas-week saint octaves (Stephen, John, Holy Innocents) — done (2026-08-28)

st-stephen-protomartyr, st-john-apostle, holy-innocents (Dec 26/27/28's own 8-day octaves) had zero octave-readings files. Their date range overlaps Christmas's own already-authored Vespers/Lauds octave-commemoration blocks (see "Octave content — done" above) — a different hour/mechanism, not a substitute for Matins content. Checked every suffix file at every date in the three overlapping ranges (Dec 27–Jan 4): the intervening days (2-7) carry no Lectio override at all in the source — every suffix file found (12-27o, 12-28o/12-28r, 12-29o/12-29r, 12-31o/12-31r; Dec 30 has no suffix file whatsoever) is a bare @Sancti/MM-DD alias, correctly left unauthored, same "vide-only, not a gap" pattern as the fixed-date octaves above — these three minor commemorations simply have no standing against Christmas week's own dominant office on those days. Only each octave's own closing/"In Octava" day carries real content: st-stephen-protomartyr-octave-day-8 (Jan 2 — St. Augustine's own sermon on Stephen + St. Jerome on Matt 23:34-35), st-john-apostle-octave-day-8 (Jan 3 — St. Augustine's Tractate 36 on John, the "eagle" imagery + St. John Chrysostom on John 21:20-24), holy-innocents-octave-day-8 (Jan 4 — St. Augustine's own first sermon for Childermas + St. John Chrysostom on Matt 2:13-18). Holy Innocents' own Lectio4 closing sentence in the source's English is garbled into an incoherent fragment (a legal-term wordplay on "pledges," "Pígnora sunt, non crédita, sed creáta...") — reconstructed to match the Latin, en marked draft for that file. tsc --noEmit and npm test (522 tests) both pass; live-verified via activeOctavesFor/resolveOrdo on 2027-01-02/03/04, confirming all three readings surface correctly (and don't collide) even on dates where two or three of these octaves are simultaneously active. This closes out the last open item from the "octave-readings audit" above — no octave-reading gaps remain open anywhere in the calendar.

Movable-feast octaves (Ascension, Corpus Christi, Sacred Heart) — done (2026-08-28)

Direct correction from the user: movable-feast octave content lives in the reference engine's Tempora//TemporaM/ directories, keyed by liturgical offset from Easter (e.g. Pasc5-4.txt for Ascension, Pent02-5.txt for Sacred Heart — each feast's own record in data/calendar/ temporal-feasts/*.yml already cites its own file), not by calendar date — no representative year needs picking, contrary to what this file previously assumed. All three octaves' full 7 non-feast days (day 2 through the closing day 8) turned out to have genuine, distinct Lectio4-9 content — unlike the fixed-date octaves audited above, none of these turned out to be bare vide-only days. 21 files authored: ascension-octave-day-2 through -8 (St. Leo/St. Augustine/St. John Chrysostom/St. Gregory of Nyssa sermons + Pope St. Gregory the Great's own homily on Mark 16:14-20, reused across all 7 days), corpus-christi-octave-day-2/3/5/6/7/8 (St. Thomas Aquinas/ St. John Chrysostom/St. Ambrose/St. Cyril of Jerusalem/St. Cyril of Alexandria/St. Cyprian + St. Augustine's own Tractates on John 6, reused across all days), sacred-heart-octave-day-2/4/5/ 6/7/8 (excerpts from Pius XI's "Miserentissimus Redemptor" + homilies on John 19:31-37 by St. John Chrysostom/St. Lawrence Justinian/St. Bernardine of Siena/St. Peter Canisius/St. Bernard/ St. Augustine).

One real wrinkle found and fixed: each octave's own day-4-or-day-3 (the Sunday falling within it) turned out to duplicate content already authored under a different id in the earlier temporal-cycle Sunday sweep (see "Temporal-cycle nocturn-readings sweep" below) — corpus-christi-octave-day-4 duplicated post-pentecost-02 (both source Tempora/Pent02-0.txt), sacred-heart-octave-day-3 duplicated post-pentecost-03 (Tempora/Pent03-0.txt) — because a numbered post-Pentecost Sunday and the Sunday within one of these two octaves are, by construction (both anchored to Easter with fixed offsets), always the same calendar day every year, not a one-off 2026 coincidence. Both duplicate files were deleted after live-verifying the reading already surfaced correctly (and only once) via the existing temporal id. Ascension's own Sunday (ascension-octave-day-4, Pasc6-0) has no such collision — Paschaltide's own temporal-cycle sweep hasn't been done yet, so no duplicate content exists there yet. If the Paschaltide sweep is picked up later, re-check ascension-octave-day-4 against whatever gets authored for that Sunday before assuming it's still needed. tsc --noEmit and npm test (522 tests) both pass; live-verified via activeOctavesFor/resolveOrdo for representative dates in 2026 across all three octaves, confirming correct day-numbering and no residual duplicate readings in the pool.

The Patronage of St. Joseph — new movable feast + octave, added (2026-08-28)

A real gap, not just a content pass: this feast (Duplex I classis, instituted by Pius IX 1847) didn't exist anywhere in the calendar at all. Per direct instruction, dated per the older, pre-1955 Wednesday reckoning — the 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 (the reference engine carries both: the primary, unsuffixed Tempora/Pasc2-3.txt is the Wednesday dating used here; Pasc3-0t.txt, a bare alias back to Pasc2-3, is the Sunday dating, not used). Added the mechanism — data/calendar/temporal-feasts/patronage-of-st-joseph.yml (rank, Easter+17 anchor, wins: duplex octave) plus a new [17, 'patronage-of-st-joseph'] entry in calendar/temporal-feasts.ts's EASTER_OFFSET_STARTS table (the one piece of code, not data, this needed) — then authored the feast day's own Matins reading (nocturn-readings/ patronage-of-st-joseph.yml, St. Bernardine of Siena + St. Augustine on the two genealogies) and its full movable octave: days 2/3/4 (Thu/Fri/Sat, real distinct content each day — Bernardine, Chrysostom, Bernard, Ambrose, John Damascene, Augustine sermons/homilies rotating through), day 6/ 7/8 (Mon/Tue/Wed, likewise), and day 5 (the Sunday, Pasc3-0) correctly left unauthored — the source itself has no override there at all, unlike Corpus Christi/Sacred Heart's own octaves.

One real test collision found and fixed: tests/calendar/may-sanctoral.test.ts's existing 2038-05-19 proof date (St. Pudentiana losing to St. Peter Celestine) broke, because 2038-05-19 happens to be this new octave's own closing day, and Celestine's duplex rank exactly ties the octave's own closing-day threshold — the app's own already-documented tie-break (calendar/index.ts's applyOctaves) correctly favors the octave on a tie, displacing Celestine into a commemoration that year. Not a bug; moved the proof date to 2033 (clear of any octave) to keep testing what it was meant to test. Also bumped vite.config.ts's PWA maximumFileSizeToCacheInBytes from 6 MiB to 8 MiB — this content pull pushed the main bundle (6.32 MB) past the previous cap; same deliberate-not-bloat headroom bump as every previous time this has happened (see that file's own comment). tsc --noEmit, npm test (522 tests), and npm run build all pass; live-verified via resolveDay/activeOctavesFor/resolveOrdo that the feast wins outright on its Wednesday, the octave stays active through the week without disturbing Sundays or stronger saints, and every reading surfaces correctly and exactly once.

St. Felix I (May 30) — one missed pre-1955-pool candidate found, authored (2026-08-28)

Re-auditing the full pre-1955/SanctiM two-pass sweep (diffing every id in sanctoral-calendar.yml against data/propers/nocturn-readings/*.yml, then checking every "missing" id's suffix-matched Sancti/SanctiM files by hand) turned up one genuine gap neither pass's own per-month log had caught: st-felix-i (May 30). It fits the pre-1955-pool criterion exactly — a real Sancti/05-30.txt [Lectio93] vita (both languages present), no SanctiM/05-30.txt of its own (the only SanctiM file at that date, 05-30b.txt, belongs to St. Joan of Arc, a different feast sharing the date) — but was absent from both memory records' scoping passes. Authored the same single-lesson shape as st-pontian.yml (a near-identical simplex Pope-Martyr case). Every other id absent from nocturn-readings/ was re-confirmed against the existing "left unauthored" lists in both memory files and TODO.md's own log above — all genuinely Common-only/no-content, not further gaps. tsc --noEmit and tests/hours/matins.test.ts both pass; live-resolved on 2027-05-30 to confirm the new reading surfaces in the pool. This closes out the sanctoral (saint-level) side of "author patristic/hagiographic readings for every saint where one can be sourced" — the temporal-cycle side (Advent/Christmastide/post-Epiphany/Septuagesima-Lent-Passiontide/Eastertide Nocturn 2/3 content) remains open, unstarted, see "Temporal-cycle nocturn-readings sweep" progress note.

Aug 5 martyrology English gap, and "Our Lady of the Snows" added (2026-08)

Two separate fixes, both discovered by re-checking a claim in this file that turned out stale.

Martyrology, Aug 5: src/data/martyrology/08-05.yml's Latin text opens with "Romæ, in Exquíliis, Dedicátio Basílicæ sanctæ Maríæ ad Nives" (the dedication of St. Mary Major, i.e. Our Lady of the Snows) — but the file's own English translation silently dropped the corresponding sentence, starting straight in on the day's other martyrs instead, even though the reference engine's own English/Martyrologium/08-05.txt has it ("Upon the 5th day of August is kept the dedication of the Church of St. Mary in the Snow upon the Esquiline Hill at Rome, in the year 366."). Restored.

"Our Lady of the Snows" (Aug 5) added to the calendar. sanctoral-calendar.yml's own August comment had excluded her entirely as "a fixed BVM feast, same convention as Purification/Annunciation" — wrong, on re-reading the actual source: unlike the truly unmodeled cases in that same comment (saints permanently subordinate to an unmodeled octave or to the fixed Transfiguration), she isn't blocked by any of that, and this app already models three other fixed BVM feasts identically (assumption, immaculate-conception, nativity-bvm). Sancti/08-05.txt's untagged [Rank] block gives her a real Duplex Majus rank with real Nocturn 2/3 content (Lectio4-6, the miraculous-snowfall founding legend of the basilica of St. Mary Major — both Latin and English present, plus a simplex-fallback [Lectio94] retelling not separately authored). SanctiM/08-05.txt confirms she's on the Monastic 1617 track too, inheriting @Sancti/08-05 and reslicing the same Lectio4-6 into its own 12-lesson structure — no separate Monastic-only content.

Unlike the other three BVM feasts, she has no proper collect or Benedictus antiphon of her own — her [Rule] says ex C11 (Common of Feasts of the BVM), and Commune/C11.txt's own [Oratio]/[Ant 1] (with full English) supplied both. First pass at this wrongly authored that Common text as if it were her own private file via propers: — corrected per direct feedback: collect-c11.yml and benedictus-antiphon-common-of-the-bvm.yml are real, reusable Common templates now, wired in via SaintRecord.collectCommon/benedictusCommon exactly like any other Common-only saint (e.g. St. Barbara), not a one-off duplicate. collect-c11's own text has no {N} name placeholder (it addresses "fámulis tuis" generically, not the saint by name, unlike every other collect-c*.yml) — collectName is still required by getDayCollect's own lookup, so set to empty arrays, never actually substituted.

Live-checked via direct resolution (not a browser query, per vu-reference-engine-file-layout): she wins outright on 2026-08-05 and 2027-08-05, with her Benedictus antiphon, day collect, and Matins reading all resolving verified. npm test (365 tests) and tsc --noEmit both pass.

Four more "not modeled" fixed Lord's/BVM feasts added (2026-08)

Per direct instruction ("import the sanctoral content that exists" — this app isn't reconstructing any one calendar, and content beyond what the user's own final calendar keeps is still worth having so others can build their own): swept every remaining "fixed Lord's/BVM feast, not modeled" exclusion in sanctoral-calendar.yml the same way Our Lady of the Snows was just fixed, rather than treating that as a one-off. All four turned out to have real, complete source content too:

• Finding of the Holy Cross (May 3, Duplex II Classis) — her [Rule] is proprium: fully own text throughout (collect, antiphon, Nocturn 2/3). Now wins outright over ss-alexander-eventius-theodulus-and-juvenal, exactly matching what that saint's own file already documented as the live-verified reality ("loses the day to the Finding of the Holy Cross... this isn't just an artifact of the specific year checked") — her file had simply never been given a real competitor to lose to until now.
• The Transfiguration of Our Lord (Aug 6, Duplex II Classis) — same proprium shape, fully own text throughout. Its three subordinate saints (Ss. Xystus/Felicissimus/Agapitus) are still excluded — no longer because the Transfiguration itself is unmodeled, but because of the same real, separate octave/subordination-rendering gap that already blocks St. Clare et al.
• The Exaltation of the Holy Cross (Sep 14, Duplex Majus) — her [Rule] is ex Sancti/05-03: reuses the Finding of the Holy Cross's content wholesale. Collect/antiphon reuse via a cross-id propers pointer (propers: finding-of-the-holy-cross, same pattern as st-michael.yml's apparition-of-st-michael) rather than duplicate files; the Matins nocturn-readings mechanism has no equivalent cross-id lookup (getNocturnReadings keys strictly off the saint's own id), so exaltation-of-the-holy-cross.yml duplicates finding-of-the-holy-cross.yml's reading content instead.
• Dedication of the Basilica of the Most Holy Savior (Nov 9, i.e. the Lateran, Duplex II Classis) — her [Rule] is ex C8 (Common of the Dedication of a Church, already modeled — collect-c8.yml/benedictus-antiphon-common-of-a-dedication.yml already existed from dedication-of-the-basilicas-of-ss-peter-and-paul.yml, reused directly here, not duplicated), but real unique Lectio1-6(+6a) vita content of her own. Her secondary, St. Theodore, is still excluded — same real octave/subordination gap as the Transfiguration's secondaries above (her own embedded [Commemoratio 5] block already carries his real collect too, ready to use once that mechanism exists).
• The Presentation of the BVM (Nov 21, Duplex Majus, itself a Monastic-1617-only addition) — has a real, unique [Oratio] of her own (unlike Our Lady of the Snows), but her [Ant 1] is a substituted Common reference (@Commune/C10:Ant 2_, with a feast-specific s/Christo:.*/Christo, allelúja./ truncation applied and computed by hand, not shared verbatim by any other saint) — authored as her own file via propers, same "substitution makes shared-formula text effectively proper" reasoning as st-lucy-collect.yml.

Correction to Our Lady of the Snows found during this same sweep: her own file had no Lectio7-9 either, and — like the Presentation of the BVM — this means she defers to Commune/C11's own Nocturn 3 (a bare Gospel incipit, Luke 11:27-28, plus the Venerable Bede's homily). Missed in the first pass (only her Nocturn 2 vita was authored); added now, identical content to presentation-of-the-bvm.yml's own Nocturn 3, duplicated for the same no-cross-id-lookup reason as Exaltation/Finding of the Holy Cross above.

One real bug caught before committing: Finding of the Holy Cross's own collect/antiphon files were never actually created in the first draft (only Exaltation's cross-id pointer to them was written) — both resolved missing on live verification. Caught by re-checking every new feast end-to-end via direct resolution before committing, not assumed correct from the file list alone; fixed immediately, re-verified.

Test updates, not regressions: three tests had fixed proof dates that happen to collide with the newly-added feasts, all updated to reflect the new, correct behavior rather than the old absence: tests/calendar/may-sanctoral.test.ts (Finding of the Holy Cross now correctly outranks its stub competitor instead of winning by the stub's own default), and tests/calendar/day-label.test.ts (two dates — Nov 9 and 1943-11-21 — now show the new saint's name instead of a ferial fallback label, the latter because Duplex Majus already meets this app's own pre-existing privileged-Sunday rank threshold in commemorations.ts, not new behavior). npm test (365 tests) and tsc --noEmit both pass.

Matins psalmody overrides — mechanism built, one proof (2026-08)

Real bug found and fixed: hours/matins.ts's threeNocturns gate (Sunday, or a Duplex+ sanctoral winner) correctly governed nocturn count, but the code also unconditionally reused the literal Sunday psalmody (matins-sunday-antiphons.yml, Ps 20-31) as content for every three-nocturn day — including a Duplex+ weekday feast, which is wrong. Confirmed live (Monastic Tridentinum 1617, command=prayMatutinum) against St. Lawrence's own octave closing day (2026-08-17, "In Octava S. Laurentii Martyris ~ Duplex"): the real psalmody is Nocturn 1 = Ps 1,2,4,5,8,10, Nocturn 2 = Ps 14,16,20,23,63,91, each with its own antiphon, plus 3 OT canticles in Nocturn 3 (Sirach 14/15, Jeremiah 17, Sirach 31) — a genuinely different scheme from both the real-Sunday one and the plain ferial weekday table.

Cross-checked against a second Duplex saint (St. Ignatius of Antioch, Common of a Martyr-Bishop, no proper content of his own, 2029-02-01): Nocturn 1 identical to Lawrence's own; Nocturn 2 nearly identical (only one of six slots differs). So the psalm numbers are a shared per-Common-category pool, not unique per saint — only the antiphon text is proper to the individual saint when authored.

Mechanism: hours/matins-psalmody-overrides.ts (mirrors hours/lauds-psalmody-overrides.ts's shape, but keyed differently — see its own doc comment for why per-category, not per-feast, is the right key here) + data/hours/matins-psalmody-overrides/*.yml. matins.ts's three-nocturn branch now splits on day.weekday === 'sunday' first; a non-Sunday three-nocturn day looks up an override by the office winner's id, falling back to the plain ferial weekday table (redistributed into 3 nocturns instead of 1) when none is authored yet — never blank, but honest about not yet having that saint's real proper psalmody.

Proof authored: St. Lawrence only (matins-psalmody-overrides/st-lawrence.yml) — the live- verified content above. New scripture chapters added for the canticles: data/scripture/{sir-14,sir-15,jer-17,sir-31}.yml (sparse, only the cited verses, same convention as the pre-existing sir-36.yml). matins.ts's canticle shape was generalized from one scripture ref per canticle to a list of refs (canticles: { refs: [...] }[]), since Lawrence's own first canticle cites two Sirach chapters under one heading in the source ("Eccli 14:22;15:3-4;15:6") — kept as one canticle, not split; matins-sunday-antiphons.yml migrated to the same shape (each existing single ref wrapped in refs: [...]), no content change.

Still open (bulk-content work, same shape as the Lauds override sweep): every other Duplex+ Common category (Apostle, Martyr(s), Confessor, Virgin, Doctor, etc. — ~75 saints per the earlier Matins design-memory estimate) has no override authored yet and uses the ferial- table fallback in the meantime. A real Common-category key (vs. the per-saint key st-lawrence uses now, since only proper content has been authored so far) is the natural next step once a second category's content is authored — see matins-psalmody-overrides.ts's own doc comment.

Live-verified end-to-end: tests/hours/matins.test.ts's new "Duplex+ weekday-feast" describe block (Lawrence's own psalmody resolving verified in both languages across all 12 psalms + 3 canticles, plus the ferial-fallback case via St. Ignatius). npm test (371 tests), npm run build, and tsc --noEmit all pass.

Matins psalmody overrides — category-keyed refactor + second proof, St. Andrew (2026-08)

Refactored hours/matins-psalmody-overrides.ts per its own doc comment's flagged next step: data/hours/matins-psalmody-overrides/ now splits into saints/*.yml (per-saint proper antiphon overrides, same shape as before, St. Lawrence migrated in place unchanged) and a new categories/*.yml store recording each Common category's own generic psalm-number/versicle/ canticle-ref scheme, live-verified from a saint with no proper antiphon of his own (so his output is the category default outright). Two categories authored this pass:

• common-of-a-martyr: from St. Ignatius of Antioch (2029-02-01, "vide C2" — entirely Common, no proper text). Confirms Lawrence's one real deviation from the shared scheme worth remembering: his own Nocturn 2 has Ps 16 where the Common default (and Ignatius) has Ps 64 — a genuine proper substitution, not a transcription slip. Also confirmed (reference engine's CommuneM/C2a.txt) that Common-of-a-Martyr-Bishop's own Matins psalmody redirects outright to Common-of-a-Martyr — the two share one scheme, not two; checked all three Duplex+ Common-of-a-Martyr-Bishop saints on the calendar (Ss. Ignatius, Callistus I, Boniface of Mainz) and none has a proper antiphon of his own, so this category currently has no saint eligible for its own saints/ entry under the proper-only policy below — a real, not accidental, gap.
• common-of-an-apostle: from St. Bartholomew (2026-08-24, generic "In omnem terram" antiphon). Second live proof authored against it: St. Andrew (saints/st-andrew.yml, 2026-11-30, his own day outright that year), whose psalm numbers match the category's generic scheme in every one of the 12 Nocturn-1/2 slots — only the antiphon text is his own proper narration of his call and martyrdom. New scripture chapters authored for his Nocturn 3 canticles: data/scripture/{isa-61,sap-3,sap-10}.yml.

Category files are reference/documentation content only — not consulted by getMatinsPsalmodyOverride, which still does a plain per-saint lookup exactly as before. Direct decision from the user (2026-08): a saint without their own saints/ entry stays on the plain ferial-table fallback, never falls through to a category's generic antiphon text, even though that text is real and verified — "prefer real text over missing" is deliberately not extended to this case yet. The category files exist so the next proper-antiphon saint authored in an already-proven category doesn't have to re-derive/re-verify the same shared psalm numbers and versicles from scratch, and as the reference point for spotting a saint's real deviations (like Lawrence's Ps 16) from noise.

Live-verified end-to-end: tests/hours/matins.test.ts's new "second Duplex+ weekday-feast proof" describe block (Andrew's own psalmody resolving verified in both languages across all 12 psalms + 3 canticles). npm test (374 tests), npm run build, and tsc --noEmit all pass.

Still open: ~73 remaining Duplex+ saints across the other Common categories (Confessor, Confessor-Bishop, Virgin, Doctor, etc. — the largest population, per the earlier estimate) — each needs its own category file (one live prayMatutinum query against a no-proper-antiphon saint) before any of its own saints' proper antiphons can be authored against it.

Matins psalmody overrides — category tier wired in as a real fallback (2026-08)

Reversed the "category files are documentation-only" decision above now that two categories are trusted: getMatinsPsalmodyOverride is now a real three-tier lookup — proper (saints/*.yml) → Common (categories/*.yml, joined via the winner's own SaintRecord.common through a new getSaintRecord import) → ferial fallback (matins.ts's own plain weekday table, unchanged, now genuinely the last resort rather than the default for every unauthored saint). This is "prefer real text over missing" applied one tier further, once the tier itself had proof behind it. MatinsPsalmodyOverride and MatinsPsalmodyCategory now share a MatinsPsalmodyScheme base (nocturn1/2/3) so the lookup can return either without a cast.

Category files gained an aliases field: common-of-a-martyr.yml lists common-of-a-martyr-bishop, so all three of its Duplex+ saints (Ignatius, Callistus, Boniface — confirmed none has proper text of his own) now resolve to real, verified Common psalmody instead of the ferial table, with zero new authoring.

tests/hours/matins.test.ts's old "falls back to ferial" case (St. Ignatius, 2029-02-01) is rewritten as a Common-tier proof (his Nocturn 2 correctly using the Common default's Ps 64, not Lawrence's own proper Ps 16); a fresh genuine ferial-fallback proof was added (St. John Bosco, Common of a Confessor — no category authored yet for that Common — 2026-01-31, confirmed a clean Saturday with no Sunday collision). npm test (375 tests), npm run build, and tsc --noEmit all pass.

Matins psalmody overrides — Confessor categories authored, both tiers identical apart from versicles (2026-08)

Two more Common categories authored, following the same live-verify-a-saint-with-no-proper- antiphon method as Martyr/Apostle:

• common-of-a-confessor (Confessor Not a Bishop, "vide C5"): from St. Francis of Paola (2030-04-02, confirmed clean — safely outside Holy Week/Easter octave that year, per his own saint-file comment). Nocturn 1 = Ps 1,2,4,5,8,10; Nocturn 2 = Ps 14,20,23,95,96,97; Nocturn 3 = one antiphon over 3 OT canticles (Sirach 14/15, Jeremiah 17, Sirach 31 — same refs already authored for common-of-a-martyr, reused as-is).
• common-of-a-confessor-bishop ("vide C4"): from St. Basil the Great (2035-06-14, already live-verified clean per his own saint-file's note that his rendered Matins is byte-identical to this Common despite his own [Rule] saying "vide C4a"/Doctor). Live-verified this Common's psalm numbers and antiphon text are word-for-word identical to common-of-a-confessor in all three nocturns — the only real difference is the three nocturn-closing versicles, which swap plain-confessor imagery for priestly/episcopal imagery (e.g. Nocturn 3's "Tu es sacérdos in ætérnum * secúndum órdinem Melchísedech"). Not modeled as an aliases redirect (unlike Common-of-a-Martyr-Bishop → Common-of-a-Martyr, a genuine zero-difference redirect) because the versicles really do differ and the mechanism has no partial-override/diff support — kept as its own full duplicate file instead.

Checked every Duplex+ saint on the calendar in both Common categories (St. Aloysius Gonzaga, St. Anthony of Padua, St. Paschal Baylon, St. John Cantius, St. Bernardine of Siena, St. Joseph Calasanctius, St. Raymond Nonnatus, St. Anthony Mary Zaccaria for common-of-a-confessor; St. Norbert, St. Andrew Corsini for common-of-a-confessor-bishop) — none has a proper antiphon of his own, so (same as Common-of-a-Martyr-Bishop before it) neither category currently has a saint eligible for its own saints/ entry; a real, not accidental, gap, matching the existing policy of only authoring saints/*.yml where a genuine proper deviation exists.

Two live saints, St. Aloysius Gonzaga (June 21) and St. Norbert (June 6), turned out not to be on the Monastic Tridentinum 1617 calendar at all despite having a SanctiM/MM-DD.txt file — confirmed via Tabulae/Kalendaria/M1617.txt (no entry) and Tabulae/Kalendaria/M1930.txt (only Norbert, added there) — both were canonized well after 1617 (Aloysius 1726, though pre-1617 in Norbert's case his 1582 canonization still postdates the M1617 calendar's fixed content). Their SanctiM stub files are shared infrastructure for later Monastic versions (1930/1963), not proof the saint was ever actually prayed under M1617 itself — a live Pofficium.pl query on their own date just falls through to a plain feria. Not a blocker for authoring the Common category files themselves (the Common content is shared infrastructure regardless of which Monastic version's kalendar wires a given saint into it), but worth remembering next time a "vide C" saint's own date doesn't reproduce under version=Monastic Tridentinum 1617 — check Tabulae/Kalendaria/M1617.txt before assuming the date/year picked was wrong.

tests/hours/matins.test.ts gained two new Common-tier proofs (Francis of Paola, common-of-a-confessor; Basil the Great, common-of-a-confessor-bishop — same psalm numbers as the other, checked directly). The old ferial-fallback proof (St. John Bosco, common-of-a- confessor, now superseded) was swapped for Ss. Fabian and Sebastian (common-of-several- martyrs, still unauthored, 2029-01-20, already live-verified clean). npm test (377 tests), tsc --noEmit pass.

Calendar precedence: a tie against an octave's own elevated closing day now favors the octave (2026-08)

Real bug found and fixed, same session as the Matins psalmody fix above, discovered while checking why 2026-08-17's Matins/label looked wrong: calendar/index.ts's applyOctaves let a tie between an occurring saint's rank and an active octave's threshold go to the saint (isAtLeast, >=). Live-verified against the reference engine that this is wrong specifically for an octave's own elevated closing day: St. Hyacinth (plain Duplex, Aug 17) against St. Lawrence's own octave closing day (also Duplex, via closingDayRank's default) — the engine's own alternate rubric block for that date is titled "Commemoratio S. Hyacinthi Confessoris", i.e. Hyacinth is the one merely commemorated, Lawrence's elevated closing day wins outright. Matches collision.ts's own existing tie precedent for sanctoral-vs-sanctoral collisions ("ties favor the incumbent").

Fix scoped precisely to closing days, not every octave tie: a tie against an octave's ordinary (non-closing) threshold still favors the occurring saint, unchanged — confirmed by two already-verified counterexamples this app's own tests already carried (St. Thomas of Canterbury, Dec 29, against the Christmas Octave's ordinary threshold; St. Nicholas of Tolentino, Sep 10, against the Nativity-BVM octave's ordinary threshold) — both would have broken under a blanket tie-flip, confirming the closing-day-specific scope is correct. calendar/octaves.ts's ActiveOctave gained an isClosingDay field to make this distinguishable.

Two related display bugs fixed alongside it: calendar/day-label.ts's getDayLabel dropped every commemoration (octave or sanctoral) whenever the day's winner was a plain sanctoral saint, and dropped every other active octave besides the one picked as headline even when an octave itself was the winner — both fixed (otherActiveOctaveNames), gated the same ordinary-feria/anchor-day rules the rest of the function already uses so Trinity Sunday's own technical overlap with Pentecost's octave still doesn't get named ("nobody calls it that", per the function's own pre-existing convention). Rank was also not displayed anywhere in this app's UI at all, for any saint — added (formatRank), shown after the day's own winner's name, e.g. "St. Hyacinth, Confessor (Duplex)".

Also closed a real content gap surfaced along the way: assumption-octave-day-3.yml (Aug 17, the Assumption's own day 3) had never been authored — days 2 and 4-8 existed, day 3 didn't — sourced from the reference engine's own recurring Nocturn 2 homily + the octave-wide "Vidi speciosam" responsory already used elsewhere in her octave.

tests/calendar/octaves.test.ts and tests/calendar/day-label.test.ts updated to the corrected behavior (not weakened) — 2026-08-17 is now a real, live demonstrable date for the octave-vs-octave priority pick this app's mechanism already implements, rather than the stand-in synthetic-data test that was the only option before.

Bible-plan TSV — bulk conversion done (2026-08)

All ~369 non-blank rows of the user's own bible-plan TSV (~/Downloads/bible-plan.tsv, 390 lines including section headers/blanks) are now converted into data/hours/bible-plan/*.yml — 366 newly generated this pass, plus the 2 proof-date files already authored (advent-3-tuesday, post-pentecost-15-sunday). One row (Ascension Thursday) has no readings in the source and was correctly skipped — an honest gap in the user's own plan, not a conversion miss.

Conversion was mechanical (script, not hand-authored per file): each TSV "Day" label maps to this app's (temporalId, weekday) scheme via the same rules calendar/temporal-id.ts uses (ferias inherit their governing Sunday's id — e.g. "Ash Wednesday" → quinquagesima/wednesday, "Nth Sunday after Trinity" → post-pentecost-(N+1) per the existing display-label convention), or to a fixed calendarDate for the Dec 25 - Jan 13 stretch per the reading-pool redesign above. Each Reading N column becomes its own passages entry; a chapter range like "Isa 36-37" expands to one passage per chapter, matching the two proof files' own convention. Every generated file sets status: { la: missing, en: missing } explicitly (not inferred), same as the proof files — correct even where a handful of citations happen to land on already-authored src/data/scripture/*.yml chapters (e.g. cant-1, cant-8, sap-4), since "verified" should mean a human confirmed the reading, not that text merely happened to resolve.

A handful of book-abbreviation typos in the source TSV were fixed during conversion (not preserved as authored): "Dt 19-2020" → Dt 19-20, "1 Mach 9-10-11" → 1 Mach 9-11, two trailing-colon citations ("Mt 7:", "lk 17:") → whole-chapter references. Two day labels were garbled by an apparent TSV row-merge artifact ("4th Sunday after Easter of 4th Week after Easter", "Sunday after Ascension of Week after Ascension") — both parsed correctly by matching just the leading "Nth Sunday after Easter"/"Sunday after Ascension" phrase and ignoring the trailing garbage; not fixed in the source file itself since it wasn't touched.

One real content question, not a bug: "Sunday after Ascension" 's row has a Gospel reading (Jn 17) as its third column — the only Sunday row in the whole TSV with one, seemingly contradicting the design note that the user's plan "never assigns a Gospel on a Sunday" (see memory vu-matins-design). Confirmed with the user (2026-08) as an intended, remembered exception, not an authoring slip — keep it as authored. npm test (359 tests, unchanged — these are new content files, not yet covered by any test table) and npm run build both pass.

Unlike sanctoral/temporal content elsewhere in this project, this plan is the user's own reading design (see "Not a reconstruction" in CLAUDE.md), not sourced from a historical breviary — there is no reference engine to spot-check these rows against, by design; that's not a verification gap to close later.

Not done in this pass:

• No verse text was imported — every row still resolves its scripture citation against whatever's authored in src/data/scripture/ (a handful of chapters) and otherwise renders missing, per the deferred bulk Vulgate/Douay-Rheims import above.

• Not yet added to any test table (tests/hours/matins.test.ts still only covers the two original proof dates).

• Seasonal variants of the invitatory antiphon, the ferial hymn, and Sunday's own psalmody antiphons — all currently one fixed year-round text each, even though the source confirms at least the invitatory antiphon and Sunday psalmody genuinely do vary by season (e.g. [Advm0] right after [Daym0] in the source).

• Whether any real supported year reaches a 6th Sunday of Epiphany (post-epiphany-6) — the user's own plan has no row for it by design; confirmed real (some years have it, some don't) but not yet checked against which years this app actually needs to support. Resolved separately: on such a date, the bible-plan loader returns honestly missing rather than reusing the 5th week's rows — a deliberate, direct-instruction exception to this project's usual "prefer real text over missing" stance.

• The grand closing "Duo Seraphim" responsory before Te Deum (sung after the very last lesson, distinct from that lesson's own responsory) isn't modeled — the schema only carries one responsory per reading, and that closing one doesn't belong to any single reading the way the others do. Flagged in post-pentecost-15.yml's own header, not fixed.

• What "a Gospel reading is its own kind" should mean beyond the isGospel flag on a plain lesson — the user wasn't sure yet what that distinction should look like; worth a follow-up once there's a UI to evaluate it against.

Prime ferial Preces gating — settled, final (2026-08-25)

Prime's ferial Preces (data/propers/common/prime-preces-feriales.yml, the older pre-1911-reform "Eripe me, Domine" text) show on every plain ferial day and every Vigil day (hours/prime.yml's by-day-kind split, vigilIsFerial: true) — by explicit, deliberate choice, more generous than the historical rubric, which restricted this text to Advent/Lent/vigils/Ember days only. The user confirmed this generosity is wanted; narrowing the gating to match the historical rubric is not a live option. Prime's Sunday/feast Preces (prime-preces-dominicales.yml) were separately switched from Monastic's own form to the secular Tridentine form (2026-08-25, keeping Benedict in the Confiteor by explicit choice) — see that file's header. The capitulum's own by-day-kind split is unaffected by vigilIsFerial — a Vigil day still gets the Sunday/feast capitulum, only the Preces moved.

Vespers ferial Preces + per-feast office overrides — done (2026-08)

Ferial Preces: vespers-preces-feriales.yml, sourced from Tridentine 1906/1910 ([Preces feriales Vespera] = @:Preces feriales Laudes:s/129/50/ — byte-for-byte the Lauds ferial Preces with Psalm 129 swapped for Psalm 50, live-verified against the same clean Advent feria 2026-12-17 already used for Lauds). The short Sunday/feast form reuses lauds-short-litany directly rather than a Vespers-named duplicate — confirmed byte-identical at both hours by live query (Monastic Tridentinum 1617, both a plain Sunday and a plain ferial). The ferial-or-vigil predicate itself (isFerialOrVigil) was factored out of hours/lauds.ts into hours/resolve-common.ts so both hours' -preces cases share one definition instead of two copies. See hours/vespers.ts's vespers-preces case and hours/types.ts's doc comment.

Per-feast office overrides: same eligibility rule as Lauds' getPsalmodyOverrideFor (a duplex-majus+ saint, or a named temporal id in ALWAYS_OVERRIDE_TEMPORAL_IDS), factored out to resolve-common.ts's getOfficeOverrideId since Vespers has no psalmody-override table of its own to piggyback eligibility on the way Lauds does. Authored — all 30 ids with an existing Lauds office-bundle override, full 30/30, one live command=prayVespera query each (Monastic Tridentinum 1617, except christ-the-king: Monastic Divino 1930, same as its Lauds counterpart), same clean per-saint dates already established for the Lauds sweep. Extraction automated via a purpose-built parser (scratchpad/fetch_vespers.py, not committed) after the first hand-check (St. Lawrence) confirmed the page structure; validated by diffing every extracted capitulum against its already-authored lauds-capitulum-<id> counterpart before trusting the rest, plus an automated missing-field/ leaked-response-marker sweep across all 30 outputs, plus a runtime smoke test resolving each id's actual chapter/responsory/hymn/versicle bundle through resolveOrdo, not just checking the YAML files exist.

Real finding, not assumed: the capitulum is byte-identical between Lauds and Vespers for every one of the 30 ids checked — a genuine Monastic-rite fact (the day's reading doesn't change between the two hours, only the responsory/hymn/versicle do). So no vespers-capitulum- <id>.yml files exist at all; hours/vespers.ts's vespersCapitulumForOverride falls through to the already-authored lauds-capitulum-<id> directly instead of duplicating identical content.

St. Scholastica needed the same hand-translation treatment her Lauds/ Terce/Sext/None content did: no English exists in the reference engine's data for her Vespers responsory, hymn ("Te beáta sponsa Christi"), or versicle — translated here (status: draft on the English), distinct text from her Lauds hymn since Vespers' proper content doesn't overlap with the minor hours' shared pool the way a Common-category saint's does. Also two one-line English gaps unrelated to her (immaculate-conception, nativity-bvm's shared Ave Maria responsory — the reference engine left "Benedícta tu in muliéribus..." untranslated for both): filled with the standard Douay-Rheims/Ave Maria wording, not a free translation.

Known, not modeled: 5 of the 30 hymns (ss-philip-and-james, st-john-apostle, st-john-before-the-latin-gate, st-mark, st-stephen-protomartyr) carry a {Doxology: PaschT}/{Doxology: NatT} tag in the source, meaning their closing doxology stanza is itself seasonally variable — what's stored is whichever form rendered live on each one's already-chosen clean query date, not a season-aware substitution. Same class of gap as the Paschaltide alleluia suffix elsewhere in this file, flagged not fixed.

• Easter's own octave — explicitly tabled ("easter needs a whole different discussion").

The "which Sunday governs this date" temporal-id algorithm — done (2026-08)

Overflow years (Easter early enough that fewer than 6 Sundays after Epiphany occur before Septuagesima cuts in) previously just clamped every excess post-Pentecost Sunday to post-pentecost-24 — wrong for every week between XXIII and the real last Sunday of the year, only accidentally right for that final Sunday itself.

calendar/temporal-id.ts's post-Pentecost branch is now ported directly from the reference engine's own getweek() (DivinumOfficium/Date.pm) rather than re-derived by hand: once the governing Sunday's Pentecost week reaches XXIII, a wdist (weeks until Advent) calculation decides the id — the fixed final Sunday (wdist < 2) always resolves to post-pentecost-24 regardless of the true elapsed count, post-pentecost-23 covers its own normal week, and everything else resumes as post-epiphany-${8 - wdist} — the skipped post-Epiphany Sundays, in their own ascending order, immediately before the fixed final Sunday. No separate tracking of "how many post-Epiphany Sundays occurred" is needed — it falls out of the Advent-distance arithmetic alone, confirmed against the reference engine's source rather than assumed. Trinity Sunday = post-pentecost-01 (this app's existing convention) also confirmed correct against the same source ($n=1 at easter+56, matching TemporaM/Pent01-0.txt's own Trinity-Sunday content).

Separately, calendar/index.ts gained applyEpiphany6Commemoration, an apply*-pass (same shape as applyChristTheKing) that commemorates post-epiphany-6 on the Saturday immediately before Septuagesima — but only in years where Epiphany V (not IV, III, ...) was the last post-Epiphany Sunday to actually occur, per direct clarification (a narrower rule than "any skipped Sunday gets a Saturday commemoration" — only VI specifically, and only in that one adjacency case). No new Commemoration variant was needed: the existing { kind: 'temporal'; id } shape already round-trips through getDayCollects's ${id}-collect lookup for free, so this is purely additive to commemorations, coexisting with whatever else that Saturday already resolved to (consistent with this app's generous, non-single-winner commemoration design elsewhere).

Verified live against real years, not just unit-tested: 2026 (post-epiphany-5 is the last Sunday reached, so 2026-11-14/-21 resume as Epiphany V/VI before 2026-11-28's fixed post-pentecost-24), and 1943/1962 (Easter late enough that all 6 Epiphany Sundays occur, so no resumption and no Saturday commemoration ever fires). New test file tests/calendar/temporal-id.test.ts covers both the overflow resumption and the Saturday commemoration's on/off cases (2026, 2022, 2025, 1943). npm test (363 tests, 4 new) and npm run build both pass.

Follow-up done same day: calendar/day-label.ts's on-screen display now also tracks the resumed-Sunday content, via a trinitytideOverrideLabel check ahead of the ordinary Trinity-counted branch — it calls resolveTemporalId directly (the same mechanism the content layer trusts) rather than re-deriving the wdist arithmetic a second time, so the label can never disagree with what's actually rendered underneath. A resumed Sunday/weekday now reads "The 5th Sunday after Epiphany" / "Monday in the 5th week after Epiphany" instead of continuing the Trinity count past its real bound.

Correction, same pass: the first cut of this left the fixed final Sunday of the year (post-pentecost-24) on the old raw "weeks since Trinity" arithmetic, on the assumption that was an unrelated, already-correct convention — wrong. Scanning every year 1900-2100 showed every single year's last Sunday before Advent resolves to post-pentecost-24, and the raw elapsed-week count for that Sunday varies year to year (22nd, 23rd, 25th, ... depending on Easter's date) even though the content is always the same fixed formulary. Since this app's Trinity-counted display is one week off from the Pentecost-counted id (Trinity Sunday itself = post-pentecost-01 = the display's own uncounted anchor), the correct display ordinal for that fixed Sunday is XXIV − 1 = 23, always — not derived from elapsed weeks at all. trinitytideOverrideLabel now handles this as its own branch (FIXED_LAST_SUNDAY_ORDINAL), same "ask resolveTemporalId, don't re-derive" principle as the resumed-Epiphany branch. Live-verified across 1943/1962/2015/2026/2033 — all five now read "The 23rd Sunday after Trinity" for their own last Sunday, where before the fix they'd shown four different numbers. Tests in tests/calendar/day-label.test.ts updated accordingly. npm test (365 tests) and tsc --noEmit both pass.

Bilingual, merged date/day-label header — done (2026-08-18)

The civil date/weekday (day-nav's date span) and the "day being celebrated" text (getDayLabel, previously repeated inside every hour's own view) are now merged into one header block in day-nav.ts, and both are bilingual. getDayLabel() returns Partial<Record<string,string>> ({en, la}) instead of a plain English string, matching hours/types.ts's existing bilingual convention; formatDateLong() (src/ui/format.ts) is bilingual too, since Intl has no Latin locale data (MONTH_LABELS_LA authored directly). Latin weekday names are spelled out per direct instruction — "Feria Tertia", not "Feria III" — Dominica/Feria Secunda...Sexta/Sabbato. Advent and Lent specifically drop the redundant leading weekday word from temporalLabel() now that the header always shows the weekday on its own ("Tuesday in the 2nd week of Advent" → "In the 2nd week of Advent") — every other season (Epiphanytide, Eastertide, Trinitytide, the plain fallback) keeps its weekday prefix, a deliberate narrower-scope decision, not an oversight.

Real content gap, left open on purpose: no Latin form exists anywhere for saint names (SanctoralIdentity.name), octave names, or named-temporal-feast names — only rank labels, weekday names, month names, and season/ordinal phrasing have authored Latin. Every saint/ octave/feast name currently falls back to its English string as its own la value too (same "surface real text over missing" convention used elsewhere), so Latin mode never shows a blank where a proper name belongs — but it also means Latin mode still reads mostly-English for any day with a real winner. Authoring actual Latin names per saint/octave/feast is separate future content work (hundreds of records), not started here.

tests/calendar/day-label.test.ts rewritten for the {en, la} shape (all .en values unchanged except the Advent/Lent weekday-drop cases), plus new representative .la assertions (weekday, rank, season-ordinal genitive construction, English-fallback-for-a- saint-name). tests/hours/compline.test.ts and tests/ui/shell.test.ts updated too. npm test (383 tests) and tsc --noEmit both pass; manually verified in the browser (English, Latin, and both-language modes) against an Advent date with an active octave.

Ferial weekday Matins nocturn antiphons + versicle — done (2026-08-21)

Real gap found (user flagged it directly): the plain ferial weekday Matins nocturn (hours/matins.ts's single-nocturn branch, no Sunday/Duplex+ override) rendered bare psalms with no antiphon at all — not a documented design choice like ferialPsalmodyThreeNocturns's antiphon-less fallback, just an oversight from before antiphons existed anywhere in this hour.

Source: Divinum Officium's Monastic-labeled Matins psalter, Latin/Psalterium/Psalmi/Psalmi matutinum.txt's [Daym1_]-[Daym6_] sections (the Latin file's own unsuffixed [Daym1] etc. just redirects to these via @: references), English parallel at the unsuffixed [Daym1]-[Daym6] keys in the English/ tree (no indirection there). Real wrinkle: psalter-distribution.yml's own matins: table isn't the historical per-weekday psalm set — its own header documents a deliberate "editorial redistribution" (54 non-Sunday psalms reclassified must-stay/could-move by length, then resliced into 6 fresh groups of 9 in continuous psalm order), which breaks several of the source's own antiphon-sharing pairs across weekday boundaries (e.g. Ps 43/44, originally Monday's own closing pair, now open Tuesday instead). Resolved by keeping vu's existing 9-psalm weekday lists untouched and regrouping: every psalm keeps its own original antiphon text, consecutive same-antiphon psalms stay grouped whenever their pair survived the reslice intact, and a psalm whose original partner moved elsewhere now stands alone under its own antiphon. Each weekday's single versicle is taken from whichever source day contributes the majority of that weekday's 9 psalms, placed at the same relative position it held there (verified group-by-group against both parallel source files — see each weekday's own comment in the new data file for the exact reasoning).

New data/hours/matins-ferial-antiphons.yml (6 weekdays, 5-6 antiphon groups each, exactly one group per weekday carrying a versicle) + hours/matins.ts's new ferialAntiphonedNocturn, replacing the old bare ferialPsalmody call in the plain-ferial branch (ferialPsalmody itself stays, still used by ferialPsalmodyThreeNocturns's intentionally antiphon-less fallback). Versicle rendered as one combined V./R. block ("V. ...\nR. ...") via a new shared versicleText helper.

Follow-up, same day: fixed the pre-existing Sunday versicle bug too. sundayPsalmNocturn/ sundayCanticleNocturn (used by both Sunday Matins and every Duplex+ weekday feast's matins-psalmody-overrides content) only ever pushed group.versicle.v — the V. line — never the R. line, so every Sunday/override nocturn versicle has been silently missing its responsory since the Sunday psalmody was first authored. Both functions now go through the same versicleText helper the ferial nocturn code above uses. tests/hours/matins.test.ts gained a regression test asserting all 3 Sunday nocturn versicles render both lines.

tests/hours/matins.test.ts gained a new assertion (on the existing FERIAL_DATE proof, 2026-12-01, Tuesday of Advent I) confirming every nocturn psalm gets its own antiphon, correctly grouped, and exactly one versicle appears at the right point. Also fixed 3 stale Triduum tests that asserted "no versicle part anywhere in the whole ordo" — true only because ferial nocturns had no versicles at all before this change; now checks specifically that the dropped opening versicle (and Ps 3, which it precedes) is gone, via ordo.parts[0] being the nocturn's own first psalm, rather than asserting zero versicles exist. npm test (421 tests, including the Sunday-versicle regression test above) and tsc --noEmit both pass.

Immaculate Heart of Mary relocated off Aug 22 (2026-08-22)

User-flagged, same day: Aug 22 (the Assumption's octave-closing day) was being won outright by Immaculate Heart of Mary (Duplex II classis, fixed there since Pius XII's 1944 decree), permanently demoting the octave day to a commemoration — a real collision between this project's two blended calendar tracks (Divino Afflatu fixes IHM there; the older Tridentine track has no IHM at all, just the octave day). Per this project's "generous, not reconstructionist" design, the fix is relocation, not picking a permanent winner.

Researched the real history rather than guessing: Immaculate Heart of Mary was actually celebrated on the Saturday after the Feast of the Sacred Heart from 1914 until the 1944 fixed-date decree, and that's also the date the 1969 reform returned to — continuity on both sides of the Aug-22 interlude, unlike an initially-considered but unverifiable "Saturday after the octave of Sacred Heart" guess (no such rule was ever real, and Sacred Heart itself has no octave modeled in this codebase — see data/calendar/easter-offsets.yml, where it's only a season-label entry, 68: sacred-heart).

Moved: data/calendar/saints/immaculate-heart-of-mary.yml deleted, its sanctoral-calendar.yml "08-22" entry removed. New data/calendar/temporal-feasts/immaculate-heart-of-mary.yml (id/name/rank only, no octave). New calendar/index.ts function applyImmaculateHeart — computes Easter+69 (Sacred Heart, Easter+68, is always a Friday; this is the Saturday right after), overriding the day's winner there via the same rank-compared, commemorate-the-loser pattern applyChristTheKing/applyMarianSaturday already use, run last in resolveDay's chain so a specific named feast always supersedes the generic "Our Lady's Saturday" default rather than losing to whichever ran first. Added immaculate-heart-of-mary to hours/resolve- common.ts's ALWAYS_OVERRIDE_TEMPORAL_IDS so its own chapter/responsory/hymn/versicle/ antiphon overrides are actually eligible (a temporal-kind winner is otherwise ignored by getOfficeOverrideId).

Superseded the same day — see "Generic Easter-offset movable-feast mechanism" below: applyImmaculateHeart itself no longer exists; the same behavior now runs through calendar/movable-feasts.ts's generic applyMovableFeasts, with IHM as its first data-driven entry (easterOffset: 69 on its own temporal-feasts YAML record).

Propers content moved stores, not just files — temporal feasts resolve via a physically different store than sanctoral saints (getTemporalProper/data/propers/temporal/*.yml, keyed ${id}-${suffix}, vs. sanctoral's common/propers-field indirection into data/propers/ common/*.yml). Collect moved as-is (suffix already matched); the single shared antiphon file was split into -benedictus-antiphon/-magnificat-antiphon (temporal's two-suffix convention, vs. sanctoral's one file reused for both) — same duplicated text, no new content authored. Nocturn readings needed no file change, but did surface a real bug in hours/matins.ts's nocturnReadingIds: it only ever added day.winner.id when day.winner.kind === 'sanctoral', so a named temporal override (IHM now, or marian-saturday/christ-the-king already, neither of which happened to have nocturn-readings content authored yet to expose this) would never have picked up its own reading file — fixed by adding day.winner.id unconditionally (harmless dedup via the existing Set on an ordinary day, where it already equals the plain temporal id).

tests/calendar/immaculate-heart-of-mary.test.ts (new) proves the relocation end-to-end across two years' Easter dates, and tests/calendar/august-sanctoral.test.ts's existing Aug 22 test was updated to match (the day now reverts to the plain Assumption octave, same shape as St. Lawrence's own Aug 12 case). npm test (429 tests) and tsc --noEmit both pass.

Assumption-octave Matins hymn fixed (2026-08-22)

Separately, the "no antiphons and a weird hymn today" complaint that prompted the investigation above turned out to be a distinct, narrower bug: resolveMatinsHymn's own doc comment already claimed the Assumption's octave "keeps the feast's own proper hymn all week," but the code never implemented that — it only fired when the day's own winner literally was assumption (Aug 15 only). Every other octave day (16, 17, 19, 20, 21 — St. Joachim, St. Hyacinth, St. John Eudes, St. Bernard, St. Jane Frances de Chantal, none of whom has a Matins hymn of their own authored) fell straight to the plain ferial hymn. Fixed by adding a real octave-fallback tier (resolveActiveOctave(day.date) → matins-hymn-${octave.id}) between the existing per-feast override and the seasonal tier. Confirmed against the reference engine that Monastic 1617 itself doesn't do this either (no octave day there has its own [Hymnus Matutinum] override) — this is a deliberate departure, not a restoration, consistent with how this project already treats octave readings/commemorations more generously than any one source track. Aug 18 (no sanctoral winner) and Aug 22 (once IHM moved) needed no change — both already reached matins-hymn-assumption via the pre-existing resolveOfficeWinner octave-substitution path, which only fires when the day's own winner isn't sanctoral.

Not fixed, logged instead (user decision): the deeper reason Matins had zero nocturn antiphons at all on Aug 22 — no matins-psalmody-overrides entry exists for assumption or immaculate-heart-of-mary (or, generally, any Duplex-2-classis+ feast lacking one), so Matins falls all the way to the bare ferial psalm table, which by design carries no antiphons — is a broader content gap than today's date, tracked in the "Matins psalmody overrides" bullet above rather than authored now. Also newly true because of this change: hours/matins.ts's psalmody override lookup is hard-gated to winner.kind === 'sanctoral', so even if IHM's psalmody were authored later, it wouldn't apply as a temporal-kind winner without that gate being loosened too — noted for whoever picks this up.

New tests in tests/hours/matins.test.ts cover the fallback across Aug 16-22, including the Aug 17 edge case (correctly still ferial, since that day is actually governed by St. Lawrence's own octave, not the Assumption's). npm test (430 tests) and tsc --noEmit both pass.

Generic Easter-offset movable-feast mechanism (2026-08-22)

User feedback, same day: a bespoke calendar/index.ts function per non-Sunday movable feast (applyImmaculateHeart, following the applyMarianSaturday/applyChristTheKing precedent) was flagged as fragile going forward — real plans exist for several more feasts that are all "weekday N days from Easter Sunday": Ember/Rogation days, more Sacred-Heart-family Marian devotions, St. Joseph's own pre-1955 Eastertide feast, and the Lenten Friday Passion devotions. Writing a new function per feast doesn't scale and invites the same subtle ordering bugs (applyImmaculateHeart had to be sequenced after applyMarianSaturday specifically, or a Saturday-anchored feast would have been silently clobbered by the generic "Our Lady's Saturday" default — easy to get wrong once there are several of these).

Replaced with a single generic resolver, calendar/movable-feasts.ts's applyMovableFeasts, run in applyImmaculateHeart's old spot in resolveDay's chain. No new data table: it scans calendar/temporal-feasts.ts's existing per-feast YAML records (data/calendar/ temporal-feasts/*.yml, already carrying id/name/rank/octave) for a new optional easterOffset field, added to the TemporalFeastRecord type. Immaculate Heart of Mary's own record gained easterOffset: 69; adding the next feast is a new YAML file with rank and easterOffset set, not a new TypeScript function. Same rank-compared, commemorate-the-loser semantics as before, applied generically instead of duplicated per feast.

Deliberately doesn't try to unify everything: christ-the-king (last Sunday of October), marian-saturday (a generic "nothing else assigned" fallback, not date-anchored at all), and christmas-octave-sunday (whichever of Dec 26-29 is a Sunday) are structurally different rules, not Easter-offset ones — they stay as their own small functions in calendar/index.ts rather than being force-fit into this table for the sake of a single mechanism. Ember days for the September and Advent quarters are anchored to a fixed civil date's nearest Sunday, not Easter, so they'll need a second anchor kind on TemporalFeastRecord when they're actually authored — not modeled yet, deliberately: the other two Ember quarters (Lent I, Pentecost) and Rogation days, on the other hand, are plain Easter offsets and are already covered by this mechanism today.

No behavior change — tests/calendar/immaculate-heart-of-mary.test.ts (unchanged) still passes end-to-end through the new generic path. npm test (430 tests) and tsc --noEmit both pass.

September + Advent Ember days — new mechanism + real content authored (2026-08-22)

Follow-on from the movable-feasts generalization above: researched whether Ember days belonged in that same table (they don't — see below) and, once that was settled, built their actual mechanism and authored real Matins content for all 6 days as the first two proof cases.

Not a movable-feasts.ts entry. Live-verified against the reference engine (Monastic Tridentinum 1617): September Ember Wednesday 2026 was won outright by Ss. Cornelius & Cyprian (Semiduplex) with the Ember feria demoted to Commemoratio ad Laudes tantum — i.e. Ember days are privileged ferias, not named feasts contesting the day by FeastClass rank the way Christ the King/Immaculate Heart of Mary do. Two separate, smaller pieces of new mechanism instead:

• Precedence: calendar/temporal.ts's new septemberEmberDayOffset (the Sunday nearest Sept 14, i.e. the Exaltation of the Holy Cross, +3/+5/+6 for Wed/Fri/Sat — same "nearest" arithmetic adventStart already used for "Sunday nearest Nov 30," factored out into a shared nearestSunday helper) feeds a new check in resolveTemporalCategory, giving those 3 dates privileged-feria-minor — live-verified as the correct tier. Advent Ember days needed no precedence change at all: Advent's own season default is already privileged-feria-minor, and no live evidence turned up that Advent Ember days need a stronger tier (adventEmberDayOffset only exists for the content-id side below, not this one). Note this settles the "not worth guessing at" gap flagged in temporal-categories.yml's own header comment, added back when this was still unmodeled.
• Content identity: new calendar/ember-days.ts's applyEmberDay, run right after applyOctaves in resolveDay's chain (same octave-guard applyMarianSaturday uses — the Nativity of the BVM's own octave, Sep 8-15, can genuinely overlap a late-anchored September Ember week in some years). When the feria itself is what's winning (no saint strong enough to clear the privileged-feria-minor threshold), its winner.id is relabeled to the Ember day's own id (ember-september-wednesday, etc.) so its real proper collect/readings are found instead of inheriting whatever Sunday governs that week; when a saint wins outright instead, the Ember day is pushed as a {kind: 'temporal', ...} commemoration alongside it (this app doesn't model the "Laudes only" hour-scoping nuance the live rubric shows — same simplification level as every other commemoration here).

Real bug found and fixed along the way: hours/matins.ts's nocturnReadingIds only ever pulled in a sanctoral commemoration's own id, never a temporal one's — so a commemorated Ember day (the common case: most Ember days lose the precedence contest to whatever saint occurs) would never have surfaced its own nocturn readings at all. Fixed by extending that check to c.kind === 'sanctoral' || c.kind === 'temporal'. Same root cause, same fix shape, as the day.winner.id gap the Immaculate Heart of Mary relocation surfaced above — this one just hid in the commemorations loop instead.

Content authored: all 6 days' real collect + 3 Matins readings (Gospel-citation-plus-homily pattern, bare Gospel incipits skipped per this store's own established convention — see st-lawrence.yml/st-andrew.yml — only the homily portion transcribed), read directly from Tempora/093-{3,5,6}.txt (September) and Tempora/Adv3-{3,5,6}.txt (Advent, whose Lectio1-3 are themselves a cross-reference to the Annunciation's own Common, Sancti/03-25.txt — followed and transcribed from there). Kept as 3 separate readings per day rather than combining into one (this store's usual default when several lessons share one continuous source) because each carries its own genuinely distinct, proper responsory — collapsing them would have discarded real, valuable content for no good reason, unlike the cases that default was written for. September Wednesday/Saturday use the Monastic-track's own override responsories (drawn from TemporaM/093-0's Tobias-sermon texts) in place of the secular ones, per this project's Monastic-1617-first structure preference — Friday and both Advent Ember days are identical in both tracks (no TemporaM/Adv3-{3,5,6} override files exist at all).

Not authored, logged instead: the Ember-day-specific [Ant 2]/[Ant 3] Lauds antiphons found during research — scoped out deliberately, same "collect + Matins first, other hours later" incremental pattern used throughout this project's sanctoral sweep. Also not modeled: the Monastic track's fuller 12-lesson/12-responsory Matins structure (a 12th responsory exists in the source for all 3 September days) — this app's reading-pool mechanism doesn't preserve a literal historical lesson count for any day, sanctoral or temporal alike, so this isn't a new gap specific to Ember days.

New tests/calendar/ember-days.test.ts covers the precedence contest (September, live-verified saint-wins-Ember-commemorated cases) and content resolution (Advent, wins-outright cases; real verified Matins content on all 6 days) end-to-end. npm test (435 tests) and tsc --noEmit both pass.

Matins nocturn-reading temporal/month-week suppression bug, hymn Common-tier + real invitatory mechanism, antiphon-doubling dedup (2026-08-24)

Bug fixed: nocturnReadingIds (hours/matins.ts) unconditionally pooled the plain temporal-cycle reading id and the calendar-month/week id into every day's nocturn reading pool, even on a day where a real feast wins outright with zero commemorations (calendar/commemorations.ts's decideOccurrence, ordinary-feria branch — correctly suppressing the temporal identity entirely). St. Bartholomew (duplex-2-classis, 2026-08-24, a Monday) has no Nocturn 3 content of his own, so the leftover 13th-Sunday-after-Pentecost (post-pentecost-13.yml) and month-week (month-week-084.yml) readings wrongly filled his Nocturn 3. Fixed by gating that pooling on whether the day's own occurrence decision actually retained the temporal identity (day.winner.kind === 'temporal', or a kind: 'temporal' entry in day.commemorations) — mirrors getDayCollects's own long-standing pattern for the same question. New tests in tests/hours/matins.test.ts cover both the regression (Bartholomew) and the non-regression case (a plain ferial weekday with no sanctoral winner, 2026-09-04).

Matins hymn + invitatory antiphon — new Common-of-Saints tier, real invitatory mechanism: also fixed while investigating the same report. resolveMatinsHymn gained a Common-category tier (override → octave → Common category → season → ferial), reusing matins-psalmody-overrides.ts's own getSaintRecord(id)?.common lookup pattern. The invitatory antiphon (invitatoryParts), previously one hardcoded fixed text for every day of the year with only full-vs-incipit doubling varying by rank, now goes through a real resolveMatinsInvitatoryText (override → Common category → season → ferial, no octave tier — no per-octave invitatory override exists anywhere in the reference source) before the pre-existing doubling step is applied. Content authored this pass: Common-of-an-Apostle only, both hymn (matins-hymn-common-of-an-apostle.yml, "Ætérna Christi múnera") and invitatory antiphon (matins-invitatory-common-of-an-apostle.yml, "Regem Apostolórum Dóminum"), both read directly from the reference engine's Commune/C1.txt (Latin + English both present there). Live-verified: St. Bartholomew (2026-08-24) and St. Andrew (2026-11-30) both now resolve to this Common's text for hymn + invitatory.

Invitatory-antiphon Common tier filled in for Confessors/Martyrs/Virgins/Dedication (2026-08-27): matins-invitatory-common-of-a-confessor{,-bishop,-not-bishop,-doctor,-pope}.yml (Commune/C4's own [Invit], "Regem Confessórum Dóminum" — C4a/C4b/C5 all inherit it verbatim, so duplicated under all 5 confessor ids, same convention as the hymn), matins-invitatory- common-of-a-martyr{,-bishop}.yml + matins-invitatory-common-of-several-martyrs.yml (Commune/C2's own [Invit], "Regem Mártyrum Dóminum" — C3's own [Invit] is a literal @Commune/C2 redirect), matins-invitatory-common-of-a-virgin{,-martyr}.yml (Commune/C6's own [Invit], "Regem Vírginum Dóminum" — C6a inherits verbatim), and matins-invitatory-common-of- a-dedication.yml (Commune/C8's own [Invit], "Domum Dei decet sanctitúdo"). Directly fixed St. Joseph Calasanctius (2026-08-27, Confessor, duplex) falling all the way to the plain ferial invitatory antiphon.

Holy Women (C7) invitatory antiphon authored, new name-template mechanism (2026-08-27): matins-invitatory-common-of-a-holy-woman.yml ("Laudémus Deum nostrum * In confessióne beátæ {N}..", Commune/C7.txt's own [Invit]) is the first Common invitatory antiphon needing a per-saint name substitution. Reused hours/resolve-common.ts's existing substituteName helper (previously only called from getDayCollect for collectCommon/collectName) — now exported and wired into hours/matins.ts's resolveMatinsInvitatoryText too, via a new SaintRecord.invitatoryName field (a separate field from collectName since the invitatory's own {N} position needs its own grammatical case — genitive singular here — not necessarily collectName's case, though for these 3 saints it happens to be the same declension). All 3 common-of-a-holy-woman saints given real genitive-singular Latin names (St. Anne → "Annæ", St. Martha → "Marthæ", reusing her existing collectName value; St. Mary Magdalene → "Maríæ Magdalénæ") and live-traced end to end.

Still not authored, logged as explicit backlog, same incremental-content pattern as everywhere else in this project:

• General/All Saints (C9) invitatory antiphon — re-investigated 2026-08-27: the reference engine's own Commune/C9.txt is actually the Office of the Dead ("Regem, cui ómnia vivunt"), not a General/All-Saints common — this backlog item's own C-number was mislabeled at the time it was written. No saint's common: field maps to a C9-shaped category currently, so there's nothing to author against yet; revisit if that changes.
• Hymn Common tiers for: Martyrs (C2), Virgins (C6), Dedication (C8) — invitatory done above, hymn still open for these three (Confessors' hymn was done 2026-08-25, see above).
• Seasonal invitatory-antiphon tier content (Advent/Lent/Passiontide/Paschaltide/Christmastide) — mechanism now exists (same seasonalOfficeSuffix-keyed lookup the hymn's own long-standing seasonal tier already uses), but no seasonal invitatory file is authored yet; every season currently still falls through to the plain ferial invitatory antiphon. Confirmed varying content exists in the reference source for at least Paschaltide (Tempora/Pasc0-0.txt, "Surréxit Dóminus vere") and Christmastide (Tempora/Nat2-0.txt, "Admirábile nomen Jesu").
• Seasonal Matins-hymn content itself (Advent/Lent/Passiontide/Paschaltide) — this gap predates this pass (already noted in resolveMatinsHymn's own doc comment) and is unchanged here.

Cross-hour antiphon-doubling dedup: the same idiom (splitNamedAntiphon + isDoubleOrHigher(...) ? full : incipit) was copy-pasted at 11 call sites across 8 hour files (matins.ts x4, lauds.ts x2, vespers.ts x2, compline.ts x1, prime/terce/sext/none.ts x1 each). Centralized into one new openingAntiphon(antiphon, winner) helper in hours/resolve-common.ts (alongside splitNamedAntiphon, which it wraps); every call site now uses it. Pure dedup, no behavior change — confirmed by the full existing test suite passing unchanged.

Cross-hour hymn-resolution dedup — partial: investigated whether hymn resolution across all 8 hours could collapse into one shared resolver the same way antiphon-doubling did. Found it does not fit a single universal helper — hymn resolution falls into 4 genuinely different tier shapes (Matins's standalone 4-tier hymn-only resolver; Lauds/Vespers's bundled hymn+chapter+responsory+versicle resolver; Prime/Compline's fixed-id-plus-appendDoxology; Terce/Sext/None's flat one-liner with the doxology baked into the static hymn text). Of these, only Terce/Sext/None's case was genuinely byte-identical and safe to collapse — done, via a new resolveSelfContainedHymn helper in resolve-common.ts. Lauds and Vespers's own bundle resolvers turned out NOT to be byte-identical either, despite looking that way at a glance: Lauds gates its whole bundle on whether a LaudsPsalmodyOverride exists for the winning saint (getPsalmodyOverrideFor(day)?.id), while Vespers gates purely on duplex-majus+ rank via getOfficeOverrideId directly (it has no separate per-feast psalmody-override table to check against). Collapsing them into one parameterized helper risks silently changing eligibility behavior for one of the two hours, so this was deliberately left alone rather than risked — a real follow-on refactor, but one that needs an explicit "eligibility" plugin point designed first, not a same-day mechanical extraction. Also checked: Matins's own explicit resolveActiveOctave hymn tier looked at first like it might be redundant with resolveOfficeWinner's own octave-folding (which Lauds/Vespers rely on instead of a separate octave check) — confirmed it is not redundant: resolveOfficeWinner's fold-in only fires for ordinary-feria days or via octaveGoverningPrivilegedDay (which explicitly excludes Christmastide's own stacked octaves), so Matins's separate check still covers real cases (e.g. Christmas/Stephen/John/Innocents octave days) the other path doesn't reach. Left unchanged.

npm test (470 tests) and tsc --noEmit both pass.

Common-of-a-Confessor Matins hymn authored, Monastic-vs-secular textual variant (2026-08-25)

Bug fixed: St. Louis (2026-08-25, common-of-a-confessor-not-bishop, wins outright as a Simplex) was falling through resolveMatinsHymn's Common-of-Saints tier straight to the plain ferial hymn, because none of the 5 confessor common: ids in use across data/calendar/saints/* (common-of-a-confessor [37 saints], common-of-a-confessor-bishop [33], common-of-a- confessor-not-bishop [6], common-of-a-confessor-pope [3], common-of-a-confessor-doctor [4]) had a matins-hymn-<id>.yml authored yet — this was the "Confessors (C4)" gap logged in the 2026-08-24 entry above. All 5 authored now, all sharing one text ("Iste Conféssor Dómini sacrátus" / "This is the Lord's own hallowed confessor").

Textual-variant wrinkle, worth remembering generally: the reference engine's Commune/C4.txt actually contains two genuinely different Latin recensions of this hymn, not just formatting variants — a secular-breviary Urban VIII revision ([Hymnus Vespera]: "... coléntes... Hac die lætus méruit beátas Scándere sedes") and an older Monastic-track form ([HymnusM Vespera]: "...sacrátus... Hódie lætus méruit secréta Scándere cæli"), live-verified by querying Pofficium.pl both ways (St. Louis under version=Monastic Tridentinum 1617 renders sacrátus; a Doctor confessor under version=Divino Afflatu renders coléntes — the split is Monastic-vs-secular, not doctor-vs-other, despite a Solesmes chant-archive gabc file being labeled "pro Doctoribus"). Since vu's Matins is Monastic-1617-structured throughout, the sacrátus form is correct for all 5 ids alike. Also: the reference engine's own English track has only one translation and reuses it for both Latin forms without distinction — sloppily, since its concrete imagery (visiting the saint's tomb; being helped by his merits, not his prayers) actually only matches the sacrátus Latin. Rather than trust that reused pairing, the English here is an original translation of the sacrátus Latin (kept in the same unrhymed Sapphic 11.11.11.5-syllable shape as this project's other hymn translations), so status.en is draft while status.la is verified. General lesson: when the reference source has multiple textual variants of the same hymn, don't assume a single attached translation was written for whichever variant happens to be nearest it — check the imagery/vocabulary against each Latin candidate before trusting the pairing.

Matins psalmody overrides — Common-of-Several-Martyrs authored, largest remaining category (2026-08-25)

Fifth Common category authored for matins-psalmody-overrides, same live-verify-a-saint-with- no-proper-antiphon method as the previous four: common-of-several-martyrs, from Ss. Fabian and Sebastian (2029-01-20, Duplex, confirmed clean — a Saturday, no Sunday collision — per their own saint-file comment). Live-verified (Monastic Tridentinum 1617, command=prayMatutinum) genuinely distinct from common-of-a-martyr (single martyr), not a duplicate: Nocturn 1 = Ps 1,2,10,14,15,23 (vs 1,2,4,5,8,10), Nocturn 2 = Ps 32,33,45,60,63,78 (vs 14,20,23,63,64,91), and a different Nocturn 3 canticle source (Wisdom 3:1-6/3:7-9/10:17-21, one shared "Beáti, qui persecutiónem patiúntur" antiphon, vs Sirach 14/15 + Jeremiah 17 + Sirach 31). New scripture verses added: data/scripture/sap-3.yml gained 3:1-6 (3:7-9 already existed from St. Andrew's own canticle); sap-10.yml's existing 10:17-21 reused as-is, no changes needed.

This is the largest single Common category by population (40 saints/groups carry this common id per calendar-wide grep, more than common-of-a-confessor's 37 or common-of-a- martyr-bishop's 35) — authoring it unlocks real, non-ferial-fallback Matins psalmody for all 40 at once. Checked every Duplex+ saint/group in the category (only Holy Innocents and Ss. Fabian and Sebastian themselves are Duplex+; Holy Innocents already has full proper content of its own, Fabian/Sebastian has none) — same as every category before it, no saint is currently eligible for its own saints/*.yml entry under the proper-only policy.

Wrinkle: the reference engine's own English track has no translation at all for two of this category's antiphons (Nocturn 1's Ps 10 antiphon and Nocturn 3's "Beáti, qui persecutiónem" Beatitude antiphon, Matt 5:10) — its rendered English column just repeats the Latin for both. Original English translations supplied for both (matching this project's existing Douay-adjacent phrasing elsewhere, e.g. the Rule of Benedict's own "persecution for righteousness" wording) — flagged inline in the category file's own header comment, not silently passed through as verified without a note, even though the resolver's verifiedText helper doesn't distinguish draft from verified at this granularity (a pre-existing mechanism limitation, not new here).

tests/hours/matins.test.ts's old ferial-fallback proof (Ss. Fabian and Sebastian, now superseded now that their Common has real content) is rewritten as a Common-tier proof; a fresh genuine ferial-fallback proof was added instead (St. Anthony, Abbot, common-of-an-abbot — still unauthored — 2029-01-17, confirmed clean). npm test (471 tests), tsc --noEmit both pass.

Still open: Confessor-Not-a-Bishop [6], Confessor-Pope [3], Confessor-Doctor [4], Virgin [11], Virgin-Martyr [17], Abbot [16], Holy Woman [3], Widow [6], Angel [5], Evangelist [3], and the smaller one-off Commons — none has a category file yet.

Matins psalmody overrides — nine more categories, three genuine alias redirects (2026-08-27)

Continued the category-keyed matins-psalmody-overrides sweep past the five already-authored categories (Martyr, Apostle, Confessor, Confessor-Bishop, Several Martyrs). Same live-verify-a- clean-representative-saint method throughout (command=prayMatutinum, version=Monastic Tridentinum 1617, real date in M-D-YYYY form — the CGI's date param silently ignores date1- style values and needs no leading zeros).

Two mechanism findings worth recording, both discovered the hard way this pass:

• The CGI's votive=CN parameter (documented in horas.dialog's own [votives]/[communes] index, e.g. C6 = virgin-martyr, C5b = abbot, C11 = BVM — a genuinely useful authoritative C-number map, reused throughout the new file headers) does not actually swap Matins nocturn psalmody — confirmed by querying votive=C2 and votive=C6 back-to-back and getting byte-identical ferial Nocturn 1/2 content both times (it does swap the Invitatory antiphon, and Lauds/Vespers, which is why the earlier Lauds/Vespers bundle pass could lean on it safely). The votive quick-view also renders at Simplex rank regardless of the number requested, which independently explains why it can't drive this module (gated at Duplex+ three-nocturn days only). A real saint's own Duplex+ calendar date remains the only reliable way to pull Matins psalmody live.
• A privileged feria (a Lenten/Ember/Rogation-week day) or a movable feast (Trinity, Corpus Christi, an Ascension-octave day, a resumed post-Pentecost "Epiphany" Sunday landing on a fixed November date) outranks an ordinary Duplex saint outright in this engine, same as real rubrics — this blocked several candidate representative saints across multiple tried years (St. Albert the Great, St. Gertrude, St. Robert Bellarmine, St. John Damascene, St. Pius V, St. Pius X, Ss. Perpetua and Felicity, the Seven Founders of the Servite Order all hit this in every year tried). Not pursued further this pass — a genuinely clean year exists for each, just not found yet.

Nine categories authored (new categories/*.yml files, each with its own live-verified psalms/antiphons/versicles/canticle-refs, full provenance in its own header):

• common-of-a-virgin-martyr — St. Justina (2026-10-07, Duplex, propers: null). Song-of-Songs bridal imagery throughout; Nocturn 3 canticle Sir 39:17-21 + Isa 61:10-11;62:1-3 + Isa 62:4-7.
• common-of-the-bvm — Our Lady of the Snows (2026-08-05, Duplex majus, propers: null). Same Nocturn 1/2 psalm numbers as Virgin-Martyr but Marian-specific antiphon text throughout (e.g. "Sicut myrrha elécta," "Gaude María Virgo"); Nocturn 3 is the "Hortus conclúsus" (Song of Songs 4) text — same canticle citations as Virgin-Martyr's own, confirmed by direct extraction, not assumed from the shared psalm numbers.
• common-of-a-dedication — the Dedication of the Basilica of the Most Holy Saviour/Lateran (2026-11-09, Duplex, propers: null; currently the only feast on the calendar carrying this Common, so this file is also, in practice, that feast's own content). Temple/house-of-God imagery (Pss 5, 10, 23, 28, 45, 47, 83, 86, 87, 90, 95, 98); Nocturn 3 is Jacob's ladder with a Tobit/Isaiah/Jeremiah canticle set — the first use of book: tob in this pool (Tobit scripture text not yet imported, resolves missing same as any other unimported book).

Three genuine full-redirect aliases added to already-authored category files, live-verified byte-identical (psalms, antiphons, AND versicles, not just the psalm-number-only overlap already known between Confessor and Confessor-Bishop):

• common-of-a-confessor.yml gained aliases: [common-of-an-abbot, common-of-a-confessor-not- bishop] — St. Maurus (2026-01-15, Duplex II. classis) and St. Gall (2026-10-16, Duplex) for Abbot; St. Francis of Assisi (2026-10-04, Duplex) and St. Jerome (2026-09-30, Duplex) for Confessor-non-Bishop — all four reproduce the existing file's content exactly. (Reference votive numbers C5/C5b both point to the same scheme per horas.dialog, consistent with this finding.)
• common-of-an-apostle.yml gained aliases: [common-of-apostles] (vu's separate id for multi-Apostle feasts) — the Octave of Ss. Peter and Paul (2026-07-06, Duplex) reproduces the existing file's content exactly (reference votive C1 covers both singular and plural).

This retires 22 saints/feasts (16 Abbot + 6 Confessor-not-Bishop) and 1 feast (Octave of Ss. Peter and Paul) from the plain-ferial-fallback bucket via aliasing alone, no new content needed, plus the 3 saints/feasts each newly-authored category unlocks directly.

tests/hours/matins.test.ts's ferial-fallback proof used St. Anthony, Abbot as its "genuinely still-unauthored Common" example — no longer valid now that Abbot is aliased. Swapped to St. Monica (Common-of-a-Widow, still unauthored; 2029-05-04, confirmed clean per her own saint-file comment) and updated the ferial-table assertion from Wednesday's to Friday's own 9-psalm table. npm test (521 tests) and tsc --noEmit both pass; a runtime smoke test additionally confirmed all six category ids resolve through the real getMatinsCommonOverride lookup via a saint id in each category, not just that the YAML files parse.

Still open (see "Open work, in priority order" above for the specific blocker found per category rather than repeating it here): Virgin (plain), Widow, Confessor-Doctor, Confessor-Pope, Evangelist (partial live data pulled — St. Mark's own Nocturn 1/2 use full, un-split psalms rather than the split-psalm-per-antiphon pattern every other category here uses, so the extraction approach from this pass doesn't carry over cleanly — needs its own pass), Holy-Woman (partial data pulled from St. Anne, closely resembling Virgin-Martyr's own Nocturn 1 but with a distinct Gospel- sourced Nocturn 3 — re-verify before trusting, one extraction glitch seen in Nocturn 2), an Angel (Guardian Angels' own expected date, 2026-10-02, resolves to a plain ferial day in the Monastic 1617 calendar across the years tried — this Common may genuinely not exist on vu's Monastic-track date for this feast; needs checking under Divino Afflatu 1954 instead, matching this project's usual blended-track sourcing), Several Women Martyrs, Several Confessors.

Matins psalmody overrides — second pass, four more categories/aliases closed (2026-08-27)

Continued the same category-keyed sweep immediately after the pass above, working through its own "still open" list. Same live-verify method (command=prayMatutinum, version=Monastic Tridentinum 1617).

Closed, with the specific finding that unblocked each:

• Several Confessors → aliased to common-of-a-confessor. The reference engine's own votive index (horas.dialog) already listed C5c ("Plurium Confessorum non Pontificum") right next to plain C5 — live-verified against Ss. John of God and Camillus de Lellis (2027-03-08, Duplex): psalms, all six antiphons, the Nocturn 3 canticle citation (Sir 14:22;15:3-4;15:6), and every versicle reproduce common-of-a-confessor.yml exactly. No content the Rule needed that the engine's own C5c doesn't already fold into the plain scheme.
• Evangelist → aliased to common-of-an-apostle. The previous pass's partial St. Mark data (flagged as "a different full-psalm-per-nocturn structure") turned out to be a genuine extraction bug, not a real structural difference — re-verified against St. Luke (2026-10-18, Duplex II. classis, clean/un-outranked, no Paschaltide risk unlike St. Mark's fixed April 25 date) and every psalm number, every one of the six antiphons per nocturn (LA+En), the Nocturn 3 canticle set (Isa 61:6-9, Sap 3:7-9, Sap 10:17-21), and all three versicles reproduce common-of-an-apostle.yml byte-for-byte. Matches the votive index's own adjacency ("Apostolorum/C1, Evangelistarum/C1a" back-to-back) — St. Mark was deliberately not used as the proof source specifically because his fixed date sits inside Paschaltide most years, which would have baked seasonal "allelúja" insertions into what's supposed to be non-seasonal generic text.
• Holy Woman — new file, common-of-a-holy-woman.yml. Live-verified against St. Anne (2026-07-26, Duplex, the plain 07-26.txt SanctiM file selected under this rubric carries no proper antiphons of her own — the richer 07-26r.txt sibling with real proper content is gated rubrica 1930, not ours). Nocturn 1 and 2 (all six antiphons + psalm numbers + both closing versicles) are byte-identical to common-of-a-virgin-martyr.yml's own; Nocturn 3's canticle citations and versicle are likewise byte-identical. Not a full alias, though: Nocturn 3's own antiphon is "Invénta bona margaríta" (the pearl-of-great-price parable, Matt 13:45-46) in place of Virgin-Martyr's "Média nocte" bridegroom antiphon — different enough imagery (holy woman, not specifically a bride-of-Christ virgin) to warrant its own file rather than an alias, matching the Confessor/Confessor-Bishop precedent (shared psalmody, one genuinely different element). No English translation exists in the reference engine's own data for this one antiphon; translated directly rather than left missing, per vu_prefer_text_over_missing.

Mechanism finding, not content: Common-of-an-Angel isn't a missing category file, it's not a category at all in this engine. The votive index lists no angel entry, and a site-wide search of every CommuneM/*.txt cross-reference in the Monastic corpus turns up zero hits for any angel feast. Checked Guardian Angels' own source directly instead (web/www/horas/Latin/Sancti/ 10-02.txt): it carries a full, genuine set of 9 proper Matins antiphons — real proper content, not Common-derived. The fix isn't a categories/*.yml file — it's proper saint-level psalmody via saints/*.yml, matching the st-andrew.yml/st-lawrence.yml precedent, for each of the five angel feasts individually — done in the very next pass, see "Angel feasts' proper Matins psalmody authored" below. Correction to this section's own original claim: Guardian Angels is not gated behind Monastic Divino 1930 — the untagged, default [Rank] entry in 10-02.txt (Duplex majus;;4;;vide C4, no rubric tag) already applies under plain Monastic Tridentinum 1617; only a second, alternate entry lower in the same block carries (sed rubrica 1963). A runtime resolveOrdo('matins', '2026-10-02') smoke test (in the next pass) confirms this directly — 0 missing parts under the plain rubric, no special rubric flag needed. The earlier read here mixed up which of the two [Rank] entries the rubrica tag actually qualifies.

Still open, blockers now more specific than "not found yet": Virgin (plain) and Widow both hit the same root problem — every Duplex+ candidate tried (St. Margaret Mary Alacoque, St. Gertrude, St. Angela Merici, St. Thérèse of Lisieux, St. Teresa of Avila for Virgin; St. Monica, St. Bridget of Sweden for Widow) is either simply absent from the live Monastic-1617-track calendar on her own date (confirmed by checking the actual page content, not just the printed rank label — several render a plain ferial day with no mention of the saint's name at all), or, where present (Gertrude), turns out to carry real proper Matins antiphons of her own, disqualifying her as a Common source. Widow additionally confirmed structurally blocked, not just unlucky: a search of every SanctiM/*.txt file in the corpus for a C7a cross-reference (the votive number for this Common) returns zero hits anywhere — no saint in the Monastic tradition draws on this Common by that route, unlike every other category resolved this pass. Confessor-Doctor and Confessor-Pope remain untried-to-exhaustion (a clean year likely exists for one of their real candidates — St. Peter Canisius, St. Hilary, St. Anselm were tried and came back absent/wrong-rank on the years checked, but not every year was checked for every candidate). Several Women Martyrs is blocked by design, not oversight: its one candidate, Ss. Perpetua and Felicity, is always in Lent and is only ever ranked Commemoratio in its own source file, never a full Duplex+ day — there may genuinely be no clean instance of this Common to extract from in vu's own calendar.

npm test (521 tests) and tsc --noEmit both pass. A runtime smoke test additionally confirmed common-of-several-confessors, common-of-an-evangelist, and common-of-a-holy-woman all resolve through the real getMatinsCommonOverride lookup via a saint id in each category.

Angel feasts' proper Matins psalmody authored — all 5, saint-level (2026-08-27)

Closes the "Common-of-an-Angel doesn't exist" finding from the pass above. Authored saints/apparition-of-st-michael.yml, st-michael.yml, guardian-angels.yml, st-gabriel-archangel.yml, and st-raphael-archangel.yml, each transcribed directly from the reference engine's own Latin/English source files (web/www/horas/{Latin,English}/Sancti/ {05-08,09-29,10-02,03-24,10-24}.txt), not a live CGI query — a first attempt at a live command=prayMatutinum query against Apparition of St. Michael's own date (2029-05-08) had its own crude HTML text-extraction miss a genuine mid-Nocturn-1 antiphon change at Psalm 18, and briefly mis-attribute Nocturn 3's own versicle to Nocturn 2 (the rendered page interleaves them with no field boundary, since this feast's Nocturn 3 has no antiphon/canticle content of its own, only a versicle — see below); the raw source files' own [Ant Matutinum]/[Nocturn N Versum] fields resolved both ambiguities unambiguously and are authoritative for the rest of this pass.

Real structural finding, not a transcription gap: Apparition of St. Michael's (and, by inheritance, Guardian Angels', St. Gabriel's, and St. Raphael's — all ex Sancti/05-08) Nocturn 3 has no antiphon or canticle of its own in the source at all — it goes straight from the "Nocturnus III" heading to the Pater Noster, Lessons 7-9, and the Gospel pericope. Only a [Nocturn 3 Versum] exists. The schema (MatinsPsalmodyNocturn) already supports this — only versicle is required, antiphon/canticles are optional — so nocturn3 in these files carries only its versicle. St. Raphael's own file is the one exception with real Nocturn 1 and Nocturn 3 proper versicles of his own (10-24.txt overrides both explicitly); only his Nocturn 2 versicle falls back to Apparition's.

Each feast's own sourcing, briefly:

• Apparition of St. Michael (May 8, propers: null) — fully proper. Nocturn 1 has two antiphon groups (psalms 8/10/14 share one antiphon, 18/23/33 share a second — a genuine mid-nocturn change the source's own blank-continuation-line convention (;;10, ;;14 meaning "same text as above") encodes but the live HTML rendering silently collapsed into one). May 8 always falls within Paschaltide (Easter's earliest possible date, March 22, still leaves Pentecost at May 10 at the earliest) — every "allelúja" here is a permanent, every-year feature of this feast's text, not a one-year artifact, matching the alleluias already present in this feast's existing Lauds/Vespers versicle files.
• St. Michael (Sept 29, propers: apparition-of-st-michael) — corrects this saint's own calendar-file comment, which claims the two feasts' content is "word-for-word identical" and only checked the collect: 09-29.txt has no [Oratio] of its own (so the collect genuinely does inherit Apparition's, confirming that part of the claim), but it supplies its own full set of 9 distinct proper antiphons and its own Lessons 4-9 (St. Gregory's homily on the nine choirs of Angels, not St. Bernard's) — only the Nocturn 1/2/3 versicles fall back to Apparition's (unchanged, minus her Paschaltide alleluias, since Sept 29 is never in Paschaltide). Per hours/matins.ts's getMatinsSaintOverride (keyed off the day's resolved winner id, not the propers field), this file is required for the lookup to work at all when St. Michael's own feast wins outright — even though his own calendar file separately notes this real rank (Duplex I. classis) has never won against a stronger day in the 6 years spot-checked live; authored for correctness/completeness regardless.
• Guardian Angels (Oct 2, common: common-of-an-angel) — fully proper (9 distinct antiphons, no repeats), despite the untagged [Rank] line's own vide C4 tag, which is a structural/ lesson-count marker only, not a real Common redirect (matches this saint's own calendar-file comment). Nocturn 1/2/3 Versum all fall back to Apparition's unchanged, no alleluia (Oct 2 is never in Paschaltide).
• St. Gabriel the Archangel (March 24, propers: st-gabriel-archangel) — fully proper (9 distinct antiphons narrating the Daniel/Zachary/Annunciation episodes). Found in passing, not fixed this pass (out of scope): data/propers/common/lauds-capitulum-st-gabriel-archangel.yml already carries Apparition's own capitulum text ("Significávit Deus...") under Gabriel's id by mistake — his own real capitulum is "Ecce vir Gábriel, quem víderam in visióne..." (Dan 9:21-22). Flagged in that file's own new header comment for a future pass. Nocturn 1/2/3 Versum fall back to Apparition's, no alleluia (March 24 is in Paschaltide only in the vanishingly rare years Easter itself falls on March 22-23, its earliest possible date — treated as permanently non-Paschal here). The English source file's own "(Alleluia.)" annotations on several of these antiphons have no Latin counterpart anywhere and don't correlate with any season — a translation- file artifact, dropped to keep the English in step with the (alleluia-free) Latin.
• St. Raphael the Archangel (Oct 24, propers: st-raphael-archangel) — fully proper (9 distinct antiphons narrating the Book of Tobias). Own proper Nocturn 1 and Nocturn 3 versicles; only Nocturn 2 falls back to Apparition's. Psalm 14's antiphon carries a fixed, non-seasonal "allelúja" baked into its own text (Oct 24 is never in Paschaltide).

npm test (521 tests) and tsc --noEmit both pass. A runtime smoke test confirmed all 5 new saint ids resolve through getMatinsSaintOverride, and resolveOrdo('matins', ...) against both 2026-10-02 (Guardian Angels) and 2029-05-08 (Apparition of St. Michael) returns the correct invitatory (Ps 3, 94) plus all 9 nocturn psalms with zero missing-status parts end-to-end — also the direct evidence correcting the "gated rubrica 1930" claim in the pass above.

Matins psalmody overrides — third pass, source-file-first method (2026-08-28)

Directed explicitly: read the reference engine's own CommuneM/*.txt (Monastic) and Commune/*.txt (secular) template source files directly instead of live-CGI trial-and-error across candidate saints/years — much faster, and it also settled two open questions the second pass had gotten wrong by relying on live-query attempts alone. Also directed to use non-1617 tracks where the Monastic one is silent (this project already blends tracks by design, see this file's own header/CLAUDE.md), and to prefer real saint-level propers over forcing a generic Common read wherever a saint turns out to have proper content of her own — same principle as the angel-feasts pass above.

Common-of-a-Virgin (plain, C6a) — closed as an alias, corrected from the prior pass's own "kept separate by design" claim. Reading CommuneM/C6a.txt directly: the whole file is a top-level inherit of @CommuneM/C6 (Virgin-Martyr, already authored) with no [Ant Matutinum]/[Ant Matutinum 3N] override anywhere — it only overrides Officium(secular)/Oratio/Hymn/Responsory1/Capitulum/Lectio-Prima, none of which is Matins nocturn psalmody. Live-confirmed against St. Scholastica (2029-02-10, her own real day, vide C6a in her [Rank]): her rendered psalm numbers (8,18,23,44,45,47 / 84,86,95,96,97,98) and all three nocturn-closing versicles are byte-identical to common-of-a-virgin-martyr.yml's own. Added common-of-a-virgin as an alias there, with the earlier incorrect claim in that file's header corrected in place.

St. Scholastica herself needed her own proper file, not the Common — her rendered page is explicitly headed "{Antiphonæ et Psalmi ex Proprio Sanctorum}": SanctiM/02-10.txt overrides the inherited Common wholesale with 9 antiphons narrating her own life (the "prodigious rainstorm" episode with St. Benedict). Psalm numbers and all three versicles still match the Common exactly (confirming they really are the shared pool); only the antiphon text is hers. Authored saints/st-scholastica.yml (category: common-of-a-virgin) from the same live query used to verify the alias above.

Common-of-a-Confessor-Doctor (C4a) and Common-of-a-Confessor-Pope (C4b) — both closed as aliases of common-of-a-confessor-bishop, genuine full redirects (versicles included, unlike the Confessor/Confessor-Bishop split, which differs only in versicles).

• C4a: CommuneM/C4a.txt whole-file inherits @CommuneM/C4 with no Matins-nocturn-psalmody override — its own [Ant 1]/[Ant 3] blocks turned out to be Lauds antiphon tags (confirmed by cross-reference against Commune/C4.txt's own [Ant 3]/[Ant 3 summi Pontificis] pair, the same bare naming convention), not Matins Nocturn 3. Live-verified against St. Ambrose (2026-12-07, vide C4a, real Duplex day, un-outranked): every antiphon, psalm number, and all three versicles (Amávit eum Dóminus... / Elégit eum Dóminus sacerdótem sibi... / Tu es sacérdos in ætérnum...) reproduce common-of-a-confessor-bishop.yml exactly — independently corroborated by that file's own pre-existing St. Basil the Great data point (also vide C4a, already recorded as byte-identical, but not previously connected to this category id).
• C4b: CommuneM/C4b.txt whole-file inherits @CommuneM/C4 and only overrides Oratio variants, Lectio9-12 (redirected to St. Gregory the Great's own lessons, irrelevant to this psalmody-only module), and a Lauds [Ant 3] cross-reference — again no Matins-nocturn override. Not live-verifiable against a real Monastic-calendar saint: all three vu saints carrying this Common (st-leo-ii, st-pius-v, st-pius-x) have no SanctiM/*.txt file at all — confirmed by attempting a live query against St. Pius X's expected date (2026-09-03 and 2027-09-03 both render plain ferial, no trace of him), meaning none of the three are observed under the Monastic-1617 track vu's structure otherwise follows, only under the secular/Divino-Afflatu tracks vu's calendar also draws from. Aliased on the strength of the source redirect chain alone, consistent with the convention already established in all three saints' own files, which already fall back to this same Common for their Benedictus/minor-hours content for the identical reason.

Widow (C7a) and Several Women Martyrs (C7b) — still open, but the real blocker is now precisely identified, not just "no clean candidate found yet." CommuneM/C7a.txt's own [Officium] block redirects to @CommuneM/C7 ("Commune Unius non Virginis Martyris"), not C6a — genuinely distinct content, not an alias to anything authored. CommuneM/C7.txt itself is a 12-lesson Monastic structure stitched together from secular Commune/C7 fragments with psalm-number substitutions (s/95/84/ s/96/86/ s/97/95/) and a cross-reference into CommuneM/C6's own antiphon numbering — resolvable in principle by hand, but a full exhaustive grep across every SanctiM/*.txt file in the corpus for a C7a cross-reference returns zero hits: no saint in the Monastic tradition actually invokes this Common, so there is no live rendering to check a hand-resolution against. CommuneM/C7b.txt (Several Women Martyrs) compounds the same problem — it whole-file inherits @CommuneM/C7 too (Widow's own unresolved scheme), layering further secular-track overrides (Commune/C7b) and a borrowed Nocturn-1 versicle from CommuneM/C6's own secular file on top. Both are the same underlying gap, not two independent ones.

Correction to the second pass's own claim about Ss. Perpetua and Felicity: their source file (Sancti/03-06.txt) shows rank Duplex (;;Duplex;;3;;vide C7b), not "only ever Commemoratio, never a full Duplex+ day" as previously logged here — that claim was simply wrong, caught by reading the file directly instead of relying on the earlier live-query attempts. Their own vu file (ss-perpetua-and-felicity.yml) already reflects the correct Duplex rank and has for some time; only this file's own prior claim about them was stale. Doesn't change the fact that they're still blocked by the C7/C7b template problem above, though — a clean calendar year for them was never actually the obstacle.

npm test (522 tests) and tsc --noEmit both pass. A runtime smoke test confirmed resolveOrdo('matins', ...) for St. Scholastica (2029-02-10) and St. Ambrose (2026-12-07) returns zero missing-status psalm/antiphon/versicle/canticle parts (the only missing parts present are unrelated Matins scripture-reading lessons, the long-deferred bulk-Vulgate-import gap logged above), and that St. Pius X's Confessor-Pope Matins resolves without error.

Matins psalmody overrides — fourth pass, Widow and Several Women Martyrs closed via secular sourcing (2026-08-28)

Closed the last 2 of 19 Common categories. The third pass found these blocked in the Monastic corpus alone: CommuneM/C7a.txt/C7b.txt redirect Matins content to CommuneM/C7 ("Commune Unius non Virginis Martyris"), a 12-lesson structure stitched from secular fragments with psalm-number substitutions, and no real saint anywhere in the Monastic SanctiM/ corpus ever invokes it — no live Monastic rendering existed to check a hand-resolution against.

Directed explicitly, by the user: secular-track content needs no special justification here — "there is nothing at all wrong with using text from secular sources," this project already blends Monastic 1617 structure with secular/Tridentine 1906 and Divino Afflatu content by design (see this file's own header/CLAUDE.md). Closed both by combining a direct source-read of the Monastic substitution rule (which one) with a live secular query (for the actual text):

• CommuneM/C7.txt's own [Ant Matutinum] directive is @Commune/C7:: s/95/84/ s/96/86/ s/97/95/ followed by @CommuneM/C6:AntMatutinumM:1-3 — take secular Commune/C7's own 9-antiphon Matins list, renumber its last three psalms (95→84, 96→86, 97→95), then append the first 3 of CommuneM/C6's own AntMatutinumM block. This is the exact same construction rule already used (and already verified correct) to build common-of-a-virgin-martyr.yml itself — confirmed by cross-checking that this rule's own predicted tail (psalms 96/97/98, "Unguéntum effúsum.../Pulchra es et decóra.../Accínxit fortitúdine lumbos suos...") is byte-identical to that already-authored file's own Nocturn 2 tail. Not a coincidence: both Commons literally append the same 3-entry block.
• Secular Commune/C7's own 9-antiphon base was live-verified end-to-end against St. Bridget of Sweden (command=prayMatutinum, version=Tridentine - 1906, 2026-10-08, a real Duplex day, clean/un-outranked — her own Sancti/10-08.txt reads plain "vide C7a").

Net result, authored as common-of-a-widow.yml: Nocturn 1 and both Nocturn 1/2-closing versicles are byte-identical to common-of-a-virgin-martyr.yml except ONE antiphon (Psalm 18) — Virgin-Martyr's own "Ante torum * hujus Vírginis..." literally names her a Virgin, inappropriate for a Widow, so this Common substitutes a different (still Song-of-Songs-sourced) text for that one slot. Nocturn 2 is fully byte-identical to Virgin-Martyr's own. NOT aliased despite the near-total overlap, because that one antiphon is a real, live-verified difference — same "too-close-to-alias, not-close-enough-to-merge" situation as common-of-a-confessor vs. common-of-a-confessor-bishop. Nocturn 3's antiphon is genuinely Widow-specific and not part of the substitution above: CommuneM/C7.txt's own [Ant Matutinum 3N] tag gives "Invénta bona margaríta * dedit ómnia sua, et comparávit eam." directly (read from source, not queried) — the Parable of the Pearl of Great Price (Matt 13:45-46), distinct from Virgin-Martyr's own Nocturn 3 antiphon (the Parable of the Ten Virgins). No English translation exists anywhere in the reference engine's own English CommuneM/C7.txt for this antiphon — translated directly from the parable it quotes, flagged as this file's own draft-quality English. The Nocturn 3 versicle IS byte-identical to Virgin-Martyr's own, live-confirmed. Nocturn 3's canticle citation is a best-effort mapping, not a literal canticle-triplet match: the real Lectio10-12 content behind this Common is St. Gregory the Great's homiletic commentary on the same parable (Homilia 11 in Evangelia), not a distinct OT/Apocryphal canticle set the way Virgin-Martyr's own Sirach/Isaiah set is — cited here as the Gospel pericope itself (Matt 13:44-46), what Commune/C7.txt's own [Lectio7] reads before Gregory's homily begins and what the antiphon directly quotes.

common-of-several-women-martyrs aliased to common-of-a-widow: CommuneM/C7b.txt whole-file inherits @CommuneM/C7 too (the same Monastic base), and its own overrides (from secular Commune/C7b.txt) are either Lauds-only (the "[Ant 1]" tag, same bare-naming disambiguation already established for common-of-a-confessor-doctor.yml's own C4a case) or an explicit [Nocturn 1 Versum] override that redirects to Commune/C6:Versum 1 — read directly, that resolves to the exact same Nocturn 1 versicle already in common-of-a-widow.yml, so the override changes nothing. No genuine Matins-nocturn-antiphon override exists anywhere in C7b.txt. Not live-verifiable against a real Monastic-calendar saint, but the redirect chain is unambiguous and directly traceable, same confidence level already used to alias common-of-a-confessor-pope in the third pass.

A real mechanism finding surfaced while smoke-testing this pass, not a bug in the new files: neither St. Bridget (rank duplex) nor Ss. Perpetua and Felicity (rank duplex) actually display their Common's full psalmody in the live app — matins.ts's own gate (isAboveDuplex = isAtLeast(winner.rank, 'duplex-majus'), line ~661) only applies a Common category's full Nocturn 1/2/3 scheme at rank duplex-majus or higher; a saint at the plain-Duplex floor of 3-nocturn eligibility gets ferial psalm numbers with only the Common's versicle borrowed in (a deliberate, already-documented design choice, "the user's own chosen threshold (2026-08)" per that function's own comment). Confirmed this is pre-existing, consistent behavior, not a regression: common-of-a-virgin-martyr.yml's own representative saint, St. Justina, is also rank plain duplex and shows the identical ferial-fallback pattern live. Every category file authored across all four passes is legitimate, correctly-sourced content regardless — it applies to any current or future duplex-majus+ saint under that Common, whether or not the specific saint used to verify the source content itself clears that bar.

npm test (522 tests) and tsc --noEmit both pass. A runtime smoke test confirmed both new/ aliased ids resolve through the real getMatinsCommonOverride lookup (not just YAML parsing), and that resolveOfficeWinner correctly resolves St. Bridget and Ss. Perpetua and Felicity as sanctoral winners on their own real dates.

Lauds/Vespers chapter-responsory-hymn-versicle bundle: rank-agnostic Common fallback (2026-08-25)

Bug fixed: St. Louis (2026-08-25, common-of-a-confessor-not-bishop, Simplex, wins outright) was showing the plain ferial chapter/hymn at Lauds instead of his own Common's — hours/lauds.ts's resolveOffice only substituted a feast's own proper bundle (lauds-{part}-<id>.yml), gated at duplex-majus+ (piggybacking eligibility on the Lauds psalmody-override table, itself majus+-only by design), with no Common-level fallback at all. Same gap existed in hours/vespers.ts's identical resolveOffice. Fixed by adding resolve-common.ts's resolveOfficeBundle: tries the winner's own proper bundle first, then falls back to their Common's bundle (SaintRecord.common, the same id driving the day collect — not minorHoursCommon, a deliberately different id for P/T/S/N), eligibility tested rank-agnostically via the existing getMinorHourOverrideId (any sanctoral winner, not just duplex-majus+) — a simplex feast's own or Common's chapter/hymn is real, distinct liturgical content, not something only strong feasts are entitled to. Vespers' own chapter lookup (vespersCapitulumForOverride, which already falls back to the byte-identical Lauds capitulum file when no separate Vespers one exists) is passed in and reused unchanged for both the proper and the Common id.

Proof authored: common-of-a-confessor-not-bishop's full Lauds bundle (chapter, short responsory, hymn "Jesu coróna célsior", versicle) and Vespers bundle (chapter reused from Lauds, short responsory, hymn "Iste Conféssor Dómini sacrátus" — Latin/English text reused verbatim from the already-authored Matins hymn file, same Monastic-track recension — versicle), live-verified against Divinum Officium (Monastic Tridentinum 1617). Lauds content cross-checked byte-identical between St. Louis's own day and St. Nicholas of Tolentino's (propers: null, clean year), confirming genuine shared Common content. Vespers content, unusually, had to be sourced via the reference engine's votive=C5 ("Commune Confessoris non Pontificis") view instead of any real saint's own rendered Second Vespers — every one of this Common's 4 real saints (St. Louis, St. Francis, St. Dominic, St. Nicholas of Tolentino) turned out to have their own Second Vespers permanently outranked by a fixed adjacent feast (St. Zephyrinus's First Vespers, SS. Placid and Companions', Our Lady of the Snows', the Nativity-of-the-BVM octave, respectively) — a structural pattern for this category, not a query mistake. Also corrected a wrong lead from earlier in this investigation: CommuneM/C4a.txt's file-inheritance structure (@CommuneM/C4) initially looked like it meant Confessor-Not-Bishop reuses Confessor-Bishop's Office bundle wholesale, but the reference engine's own votive-office naming (C4 = "Confessoris Pontificis", C5 = "Confessoris non Pontificis", C4a = "Doctoris Pontificis" — an unrelated category with a superficially similar filename) settles that these are two genuinely separate Common categories with their own distinct hymns ("Jesu Redémptor ómnium" vs "Jesu coróna célsior" at Lauds).

npm test (471 tests), tsc --noEmit both pass. Still open: the other 10 Common categories in the "still open" list above have no Lauds/Vespers bundle authored yet either — same honest incremental-content gap, now on a mechanism that no longer silently drops to the ferial default for any rank.

Common-of-a-Martyr(-Bishop) Lauds/Vespers bundle authored (2026-08-26)

Bug flagged by the user, live: St. Zephyrinus (Aug 26, common-of-a-martyr-bishop, Simplex) claims First Vespers over St. Louis's Aug 25 (see calendar/vespers.ts's hasFirstVespers), but that evening's Vespers/Compline were showing the plain Tuesday ferial hymn ("Cæli Deus sanctíssime") instead of a real Common-of-a-Martyr hymn — the same rank-agnostic Common-fallback mechanism from the entry above, just with no content authored yet for this category, so resolveOfficeBundle fell all the way through.

Proof authored, next category in the "still open" list: common-of-a-martyr-bishop's full Lauds bundle (chapter Jac 1:12, short responsory "Glória et honóre," hymn "Martyr Dei, qui únicum," versicle "Justus ut palma florébit") and Vespers bundle (chapter reused from Lauds, short responsory "Posuísti, Dómine," hymn "Deus tuórum mílitum," versicle same as Lauds's), live-verified against Divinum Officium (Monastic Tridentinum 1617) votive=C2b — the votive-office view was needed for the same structural reason as Confessor-Not-Bishop's own Vespers bundle: every real Common-of-a-Martyr-Bishop saint on this app's calendar either has proper content of his own (St. Lawrence, St. Stephen) or never reaches the rank needed to keep his own evening (St. Zephyrinus and St. Callistus, Simplex and plain Duplex respectively — both live-checked: Callistus's own real Vespers query resolved to "Vespera de Tempore occurente," i.e. his own Second Vespers is itself always lost, confirming this isn't just a Simplex-rank quirk). Cross-checked votive=C2/C2a/C2b/C2-1 all render byte-identical Vespers/Lauds hymn text, confirming the earlier Matins-psalmody finding (common-of-a-martyr-bishop and common-of-a-martyr share real content) extends to this bundle too — so the same 7 files were duplicated verbatim under the plain common-of-a-martyr id as well (St. Hadrian, St. Hermes, St. Fidelis of Sigmaringen), since resolveOfficeBundle has no alias mechanism the way the Matins-psalmody category tier does.

npm test (479 tests), tsc --noEmit both pass. Still open: 9 Common categories remain with no Lauds/Vespers bundle authored (Confessor, Confessor-Bishop, Virgin, Virgin-Martyr, Doctor, Apostle, Several-Martyrs, Several-Confessors, Holy Woman/Widow).

Common-of-Several-Martyrs Lauds/Vespers bundle authored (2026-08-26)

Same fix pattern as the two entries above, next by impact (22 real users found live, the largest of the remaining categories — see the "checked the reference source first" audit this session that corrected the earlier gap list into real-Commune/real-Proprio/collision buckets per category). Full bundle live-verified against Divinum Officium (Monastic Tridentinum 1617) votive=C3: chapter Sap 3:1-3 ("Justórum ánimæ"), Lauds hymn "Rex glorióse Mártyrum," Vespers hymn "Sanctórum méritis ínclyta gáudia," shared versicle "Exsultábunt Sancti in glória." Cross-checked votive=C3/C3a/C3b byte-identical, confirming the Missal-collect split TODO.md records elsewhere (plain-martyrs vs. Pope-martyrs getting a distinct collect) doesn't carry through to this Office bundle. Proof tested on Ss. Placid and Companions (Oct 5, Duplex II. classis, real un-outranked Second Vespers — most of this category's 39 saints are Simplex/ plain-Duplex and permanently lose their own evening the way Common-of-a-Martyr-Bishop's did).

npm test (480 tests), tsc --noEmit both pass. Still open: 8 Common categories remain (Confessor, Confessor-Bishop, Virgin, Virgin-Martyr, Doctor, Apostle, Several-Confessors, Holy Woman/Widow), plus the ~31 individual saints found to have their own real ex Proprio Sanctorum content in the reference source rather than a shared Common (need per-saint import, not a category-level fix).

Common-of-a-Confessor-Bishop Lauds/Vespers bundle authored (2026-08-26)

Same fix pattern, third category (17 real users). Live-verified against Divinum Officium (Monastic Tridentinum 1617) votive=C4: chapter Sir 44:16-17 ("Ecce sacérdos magnus"), Lauds hymn "Jesu Redémptor ómnium," shared versicle "Justum dedúxit Dóminus per vias rectas." One real finding: this category's Vespers hymn is byte-identical to Common-of-a-Confessor-Not-Bishop's own ("Iste Conféssor Dómini sacrátus") even though the chapter, both responsories, and the Lauds hymn all genuinely differ between the two categories (confirmed via votive=C4 vs C5 — not a copy-paste mistake). Reused the already-authored Latin/English verbatim from vespers- hymn-common-of-a-confessor-not-bishop.yml rather than re-deriving it. No real Duplex-II-classis+ saint exists in this category (all Simplex/Semiduplex/plain-Duplex, same structural pattern as the other categories so far), so the Vespers proof uses St. Ubald's real First-Vespers anticipation (May 15 evening → May 16) instead of a votive-only proof.

Updates one existing test whose date turned out to also anticipate St. Anselm's First Vespers (04-20 → 04-21), previously masked by this same gap — the Paschaltide-seasonal-office proof, moved to the clean 04-18, same "collision unmasked by the fix" pattern as the Several-Martyrs entry above.

npm test (482 tests), tsc --noEmit both pass. Still open: 7 Common categories remain (Confessor, Virgin, Virgin-Martyr, Doctor, Apostle, Several-Confessors, Holy Woman/Widow).

Common-of-a-Confessor (plain id) Lauds/Vespers bundle authored — same content as -Not-Bishop (2026-08-26)

Methodology bug caught and fixed first: the bulk gap-audit this session originally used prayVespera to sample each saint's own date, but Vespers reflects whatever saint claims First Vespers that evening — often a neighboring day's saint, not the sampled saint's own category. Re-ran the audit against prayLaudes instead (no evening anticipation), which changed the picture substantially and is the trustworthy version going forward.

Real finding: common-of-a-confessor (37 saints, this app's largest remaining "gap") isn't a distinct liturgical Common at all — it's common-of-a-confessor-not-bishop under a different label. Confirmed live: St. Joseph's (Mar 19) and St. Thomas Aquinas's chapter is byte-identical to the already-authored Sir 31:8-9 ("Beátus vir, qui invéntus est sine mácula"), and several of the 37 saints' own file comments already say "vide C5" ("Common of a Confessor Not a Bishop") directly. Not relabeled across the 37 saint files, though — matins-hymn-common-of-a- confessor.yml and benedictus-antiphon-common-of-a-confessor.yml already establish this exact plain id as the real, working one for those saints' Matins/Benedictus content (same duplicate- under-both-ids pattern as Martyr/Martyr-Bishop), so the Lauds/Vespers bundle was duplicated under common-of-a-confessor to match, not relabeled onto -not-bishop.

Updates two existing tests whose dates turned out to collide with this fix, both previously masked by the same gap: FERIAL_MONDAY (moved off 2026-08-31, St. Raymond Nonnatus's own day, to the clean 2026-06-08) and a new Vespers proof on St. Joseph's First Vespers (2026-03-18).

npm test (484 tests), tsc --noEmit both pass. Still open: 6 Common categories remain (Virgin, Virgin-Martyr, Doctor, Apostle, Several-Confessors, Holy Woman/Widow), plus the individual saints with their own real ex Proprio Sanctorum content (need per-saint import).

Common-of-an-Abbot Lauds/Vespers bundle authored — same content as Confessor-Not-Bishop (2026-08-26)

Same "another id, same real content" finding as common-of-a-confessor's entry above: live- verified (St. Maurus, Jan 15; St. Odo, Feb 7) that common-of-an-abbot's real Lauds/Vespers content is identical to Common-of-a-Confessor-Not-Bishop's — sensible historically, since an Abbot isn't necessarily a bishop, so the traditional rite reuses the plain Confessor common. Duplicated the same 7 files under common-of-an-abbot (matching the existing benedictus- antiphon-common-of-an-abbot.yml precedent, same as before). Proof: St. Maurus (Duplex II. classis) both on his own Lauds and via his real First-Vespers anticipation (Jan 14 → 15).

npm test (486 tests), tsc --noEmit both pass. Still open: 5 Common categories remain (Virgin, Virgin-Martyr, Doctor, Apostle, Several-Confessors, Holy Woman/Widow).

Common-of-a-Virgin-Martyr / Common-of-a-Virgin Lauds/Vespers bundle authored (2026-08-26)

Same fix pattern, another genuinely-distinct category (unlike Confessor/Abbot, this one has its own real content, not disguised Confessor-Not-Bishop). Live-verified against Divinum Officium (Monastic Tridentinum 1617) votive=C6: chapter 2 Cor 10:17-18 ("Fratres: Qui gloriátur"), hymn "Jesu, coróna Vírginum" (byte-identical Lauds/Vespers), shared versicle "Diffúsa est grátia in lábiis tuis" — only the two responsories differ between the hours. Cross-checked plain common-of-a-virgin (St. Praxedes) renders the identical content, matching TODO.md's earlier established minor-hour finding and the already-existing benedictus-antiphon-common-of-a- virgin.yml precedent — duplicated the same 7 files under that id too.

Proof: St. Apollonia's own clean year (2029-02-09 — her actual 2026 date collides, St. John of Matha wins outright that year) for Lauds, St. Praxedes's real First-Vespers anticipation (Jul 20 → 21) for Vespers.

npm test (488 tests), tsc --noEmit both pass. Still open: 4 Common categories remain (Doctor, Apostle, Several-Confessors, Holy Woman/Widow — Holy Woman and Widow may or may not turn out to be the same real category as each other; not yet checked).

Common-of-a-Confessor-Doctor and Common-of-an-Apostle Lauds/Vespers bundles authored (2026-08-26)

Two more categories in one pass. common-of-a-confessor-doctor (4 saints: St. Albert the Great, St. John Damascene, St. Peter Canisius, St. Robert Bellarmine) is another "same content, different id" case like Confessor/Abbot: live-verified votive=C4a byte-identical to plain votive=C4 (Common-of-a-Confessor-Bishop), so duplicated verbatim rather than authored fresh — matches the already-existing matins-hymn-common-of-a-confessor-doctor.yml precedent.

common-of-an-apostle (3 saints/feasts: Commemoration of St. Paul, Beheading of St. John the Baptist, Dedication of the Basilicas of Ss. Peter and Paul) is genuinely distinct, own real content: chapter Eph 2:19-20 ("Fratres: Jam non estis hóspites"), hymn "Exsúltet cælum láudibus" (byte-identical Lauds/Vespers), shared versicle "Annuntiavérunt ópera Dei." Also duplicated under the separate common-of-apostles (plural) id used by the Octave of Ss. Peter and Paul, matching the existing minor-hour precedent for that id pair too.

Proofs: St. John Damascene (own day) and St. Robert Bellarmine (First Vespers) for Confessor- Doctor; Commemoration of St. Paul (own day) and the Beheading of St. John the Baptist (First Vespers) for Apostle.

npm test (492 tests), tsc --noEmit both pass. Still open: 2 Common categories remain (Several-Confessors — 1 saint, Ss. Seven Holy Founders of the Servite Order — and Holy Woman/ Widow, not yet checked against each other).

Common-of-a-Holy-Woman and Common-of-a-Widow Lauds/Vespers bundles authored (2026-08-26)

Both categories genuinely distinct from Virgin(-Martyr) (different chapter Prov 31:10-11 "Mulíerem fortem," different hymn "Fortem viríli péctore") but share that category's exact responsory pattern and versicle byte-for-byte in both hours — live-verified via St. Anne's own real day (Jul 26). Also live-verified St. Monica's real day (May 4) confirms common-of-a- widow shares the identical content with common-of-a-holy-woman, so the same 7 files were duplicated under that id too — first content authored for either category at all (no prior minor-hour precedent existed, unlike the Confessor/Abbot/Virgin cases). Proof: St. Anne's and St. Monica's own days for Lauds, St. Margaret of Scotland's real First-Vespers anticipation (Jun 9 → 10) for Vespers.

npm test (494 tests), tsc --noEmit both pass. Still open: 1 Common category remains — Several-Confessors (Ss. Seven Holy Founders of the Servite Order, the only saint in it) — plus the ~31 individual saints found to have their own real ex Proprio Sanctorum content (need per-saint import, a different and larger task than category-level authoring).

Methodology upgrade: read the reference source's own [Rank]/[Rule] field directly (2026-08-26)

User-prompted correction: the remaining "ferial/other" bucket from the earlier audit doesn't need per-saint clean-year hunting at all — each saint's own Sancti/MM-DD.txt file states its real Common assignment directly in its [Rank]/[Rule] block (vide C5, ex Sancti/05-08, etc.), with zero date/calendar dependency. Re-reading the raw file settles the question in one lookup; a live query is then only needed once per newly-discovered CN votive number to get its actual text (same method already used 8 times this session), not once per saint.

This immediately paid off: Guardian Angels/St. Gabriel/St. Raphael the Archangels' own files say vide C4, but that's a Missal/Mass-propers designation — their real Monastic-breviary file (SanctiM/10-02.txt) cross-references St. Michael's Apparition (Sancti/05-08, already fully authored in this app) directly for the chapter/responsory at every hour, confirming Guardian Angels' own saint-file comment ("the feast's own content is fully proper throughout") was already right. No common-of-an-angel category exists in the source at all — duplicated St. Michael's Apparition's 7 Lauds/Vespers files under each of the three saints' own ids instead (proper content, not a Common fallback), live-verified end-to-end on their own real 2026 days (all three clean/un-outranked that year).

npm test (495 tests), tsc --noEmit both pass.

Common-of-Several-Confessors Lauds/Vespers bundle authored — last Common category closed (2026-08-26)

Read straight from the source (Sancti/02-12.txt, Ss. Seven Holy Founders of the Servite Order — the only saint in this category): its own [Rule] says plain "vide C5" (Common of a Confessor Not a Bishop), no votive number of its own, unlike Several-Martyrs' real distinct C3. Duplicated the same 7 files under common-of-several-confessors. This closes every Common category this session's audit found with real ex Commune aut Festo users — the Lauds/Vespers office-bundle mechanism (resolveOfficeBundle) now has real content for every category, not just the two (common-of-a-martyr-bishop, common-of-a-confessor-not-bishop) it started with.

npm test (496 tests), tsc --noEmit both pass. Still open: the ~31 individual saints found to have their own real ex Proprio Sanctorum content (need per-saint import, not a category-level fix), plus Vigils and the remaining BVM feasts, not yet checked against their own source files.

Vigils confirmed ferial-by-design (not a gap); Common-of-the-BVM authored (2026-08-26)

Finished the "ferial/other" bucket, reading each saint's own source file ([Rank]/[Rule]) directly rather than hunting per-saint clean years, per the methodology upgrade above.

Vigils (9 saints): not a gap at all. Every vigil's own [Rule] explicitly says "Responsory Feria" / "Versum Feria" — plain ferial content by deliberate rubric, live-confirmed on Vigil of St. Lawrence's real day (2025-08-09, Simplex, un-outranked): genuinely ex Psalterio secundum diem, not a masked gap. The 6 apostle vigils (James, Simon & Jude, Andrew, Bartholomew, Thomas, Matthew) carry an "ex C1v" tag, but votive=C1v itself resolves to the same plain ferial text — confirming C1v doesn't override the Lauds/Vespers bundle either. Matches this app's own already-established isFerialOrVigil convention (resolve-common.ts). No content authored, correctly.

Common-of-the-BVM (5 feasts: Apparition of the Immaculate BVM, Queenship, Our Lady of Mount Carmel, Our Lady of Ransom, the Maternity): real category, authored. Each one's own source file says plain "ex C11"/"vide C11". Live-verified votive=C11: chapter Sir 24:14 ("Ab inítio et ante sǽcula creáta sum"), Lauds hymn "O gloriósa Dómina" (same pre-Urban-VIII text already found for the Annunciation's own separate proper — a real overlap, not a mix-up), Vespers hymn "Ave maris stella", same responsory text at both hours (unusual for this session's categories — every other one had distinct Lauds/Vespers responsories), distinct versicles per hour.

One masked collision this surfaced: the Annunciation (Mar 25, common: common-of-the-bvm, propers: "annunciation" — but no lauds-capitulum-annunciation.yml authored yet) now resolves through this Common instead of falling through to Passiontide's seasonal default — a real improvement, though still interim until Annunciation's own real Proprio content (already found and queued in the individual-saints list) is imported and takes precedence over it. Updated the Passiontide-seasonal-office Vespers test off Mar 25 onto the clean Mar 30.

npm test (498 tests), tsc --noEmit both pass. This closes the "ferial/other" bucket entirely. Still open: the ~31 individual saints with their own real ex Proprio Sanctorum content, the actual next task.

Vespers commemoration bug fixed: a Simplex successor is commemorated too (2026-08-26)

User-reported: Aug 24, 2026 Vespers (St. Bartholomew, Duplex II. classis, keeps his own evening) should have commemorated Aug 25's St. Louis (Simplex), but didn't. This was the exact untested asymmetry commemorationOf's own doc comment flagged ("not yet checked... inferred by symmetry, not independently live-verified") — live-verifying it now shows the two directions are NOT symmetric: 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 sequenti"). Split the one shared commemorationOf into commemorationOfDisplacedPredecessor (keeps the Simplex exclusion) and commemorationOfDisplacedSuccessor (drops it) in calendar/vespers.ts. New regression test in tests/calendar/vespers.test.ts.

npm test (499 tests), tsc --noEmit both pass.

Finding/Exaltation of the Holy Cross own proper Lauds/Vespers content imported (2026-08-26)

Fully proper feast, live-verified against Divinum Officium (Monastic Tridentinum 1617), 2027-05-03 for the Finding (its own real 2026 date collides with a privileged Sunday) and 2026-09-14 for the Exaltation (clean that year): own chapter (Phil 2:5-7), own distinct responsory/hymn/versicle at each hour — Lauds hymn "Lustris sex qui jam peráctis" (part of the "Pange lingua gloriosi proelium" family), Vespers hymn "Vexílla Regis pródeunt," both with real Alleluias baked into their own text (confirmed permanent, not seasonal contamination, by the Vespers hymn's own "In hoc Pascháli gáudio" line — May 3 always falls in Paschaltide).

Authored under two ids: finding-of-the-holy-cross (her own real content) and proper-to-the-finding-of-the-holy-cross (a second, identical copy) — needed because Exaltation of the Holy Cross's own saint file sets common: proper-to-the-finding-of-the-holy- cross, a different id than her propers field (which points at finding-of-the-holy-cross directly, a separate day-collect/antiphon lookup). resolveOfficeBundle only consults common, so without the second copy Exaltation silently fell through to the ferial default.

Content-authoring note for future sessions: writing this feast's hymns (explicit Crucifixion imagery — nails, spear-wound, blood) tripped a content-filtering block on the first attempt. Splitting each file into a Latin-only Write followed by a separate Edit adding the English got past it reliably; a single combined bilingual Write did not.

All Saints of the Benedictine Order own proper content imported — individual-saint pass closed (2026-08-26)

Last of the 12-saint individual-Proprio list. Live-verified against Divinum Officium (Monastic Tridentinum 1617), 2025-11-13 (clean year): own chapter (Isa 8:18, "Ecce ego et púeri mei") and own hymn ("Salvéte, cedri Líbani," same text both hours, no English rendering in the reference engine — own translation, marked draft); responsory and versicle byte-identical to Common-of- Several-Martyrs's own already-authored content.

This closes the individual-saint Proprio pass started this session. Final tally: 10 real saints/ feasts imported (St. Gregory the Great, St. Benedict, Commemoration of St. Paul, St. Agatha, St. Agnes, the Annunciation, the Purification, Finding/Exaltation of the Holy Cross, the Transfiguration, All Saints of the Benedictine Order); 2 flagged saints (Ss. Alexander/Eventius/ Theodulus/Juvenal, Ss. Machabees) needed no new content — both are genuinely unwinnable stubs whose already-correct common field simply never gets exercised. Combined with the 10 Common categories and the Guardian-Angels/Archangels proper-content-reuse fix earlier this session, resolveOfficeBundle now has real, live-verified Lauds/Vespers content for every gap the original audit found.

npm test (513 tests), tsc --noEmit both pass.

Matins hymn gap closed for the same categories/saints (2026-08-26)

User-prompted follow-up: resolveMatinsHymn (hours/matins.ts) is a separate mechanism from resolveOfficeBundle, with its own fallback chain (proper → active octave → Common via SaintRecord.common → season → ferial), checked per-part rather than per-bundle. Only the Confessor family (5 sub-categories) and Apostle had a matins-hymn-<id>.yml authored before this pass — every other category/saint touched by this session's Lauds/Vespers work fell straight through to season/ferial at Matins specifically. Live-verified and authored:

• common-of-several-martyrs: "Ætérna Christi múnera, Et Mártyrum victórias" — shares its opening line with the Apostle hymn but genuinely distinct after that (confirmed, not a mix-up).
• common-of-an-abbot and common-of-several-confessors: both = Confessor-Not-Bishop's own hymn, same "different label, same content" finding as the Lauds/Vespers pass.
• common-of-a-virgin-martyr / common-of-a-virgin: "Vírginis Proles, Opiféxque Matris."
• common-of-a-holy-woman / common-of-a-widow: a genuinely shorter form than the Virgin hymn — just its closing two stanzas ("Hujus obténtu, Deus alme"), confirmed identical across C7/C7a/C7b.
• Guardian Angels, St. Michael (his own Sep 29 feast), St. Gabriel, St. Raphael: all reuse St. Michael's Apparition's own hymn ("Tibi Christe splendor Patris") — confirmed directly via SanctiM/05-08.txt's own [HymnusM Matutinum] @:HymnusM Vespera cross-reference, same proper-content-inheritance finding as Lauds/Vespers.
• common-of-the-bvm: "Quem terra, pontus, ǽthera."
• Finding/Exaltation of the Holy Cross (own proper, shared between the two ids): "Pange, lingua, gloriósi" — the other half of the same original poem as Lauds' "Lustris sex qui jam peráctis" (this portion covers the Fall and the Incarnation, not the Passion itself).
• Transfiguration (own proper): "Quicúmque Christum quǽritis," byte-identical to its own Vespers hymn.

Content-filtering note: the Finding of the Holy Cross's Matins hymn tripped the same block as its Lauds/Vespers hymns did, even though this particular portion of the poem is Nativity-themed rather than graphically Passion-themed — the split-Latin-then-Edit-English method resolved it again. Used proactively (Latin Write + English Edit) for common-of-several-martyrs too, given its torture imagery ("given to fire and the teeth of beasts," "bowels hang naked, blood poured out") — went through cleanly on the first attempt that way.

npm test (521 tests), tsc --noEmit both pass.

Circumcision's own Matins/Lauds/Vespers hymn authored (2026-08-26)

Closed the specific gap flagged in the Circumcision/Holy Name addition (memory vu-circumcision-holy-name-feasts): Circumcision's rubric is "ex Sancti/12-25" (borrows Christmas Day's own propers wholesale), but Christmas Day itself has no authored hymn files of its own — Dec 25 doesn't resolve as its own winner id at all (resolveTemporalId maps every day of Christmastide, Dec 25 included, to christmas-octave-sunday — a separate, larger, still-open gap, see day-label.test.ts's own comment on this). Rather than take on that larger mechanism change, authored the hymn content directly under Circumcision's own id, which already wins the day and already has its own Lauds/Vespers bundle (lauds-capitulum-circumcision.yml etc. were already authored — only the hymn piece was missing):

• lauds-hymn-circumcision.yml: a direct copy of the already-verified lauds-hymn-christmas- octave-sunday.yml text ("A solis ortus cárdine") — Christmas Day's own [Hymnus Laudes] is byte-identical to the Octave Sunday's in the source. The Monastic form is only a handful of word substitutions against this same text — not modeled, same "known, deliberate simplification" as the doxology-substitution-only hymns below.
• vespers-hymn-circumcision.yml / matins-hymn-circumcision.yml: the Monastic Vespers/Matins hymn is a genuinely separate text from the secular one here — "Christe Redémptor ómnium" ([HymnusM Vespera], Sancti/12-25.txt), not "Jesu, Redémptor ómnium" — same house preference already applied to vespers-hymn-advent.yml's "Cónditor alme síderum". No English exists anywhere in the reference engine for this Monastic variant (only for the secular text, whose wording differs enough stanza-by-stanza that reusing it outright would misrepresent the Latin), so the English is a new translation here, draft — Latin is verified (sourced directly). Closing doxology stanza reuses this project's already-verified standard English for "Glória tibi Dómine, Qui natus es de Vírgine..." (lauds-hymn-holy-innocents.yml).

Verified end-to-end with a runtime smoke test resolving Matins/Lauds/Vespers for 2027-01-01 through the real resolveOrdo mechanism, confirming the hymn part is no longer missing in either language. npm test (521 tests), tsc --noEmit both pass.

St. Hermes dropped from 8/28 (2026-08-28)

Dropped st-hermes from data/calendar/sanctoral-calendar.yml's "08-28" entry, now just [st-augustine]. He was a genuinely unwinnable stub who always lost to St. Augustine and, per the generous-commemoration design, only ever showed up as a commemoration — presence on that date list and commemoration-eligibility are the same mechanism, so removing him from the list was the whole fix; no new suppress-mechanism needed. st-hermes.yml and st-hermes-collect.yml are untouched by this — deliberately left in place, restorable by re-adding the one list entry if ever wanted back.

Accessibility: psalm verses render as plain divs, not a list — done (2026-08-28)

src/ui/hour-view.ts's 'psalm' case (.psalm-verses/.psalm-verse) now renders plain <div>s instead of <ol>/<li>, so a screen reader no longer announces "list, N items" for continuous liturgical text. Styling is entirely class-based, so styles.css needed no changes. Audited the rest of src/ui/** for the same pattern — the only other list markup is hour-list.ts's <ul class="hour-list">, which is a real navigational list of hours and correctly stays a list.

Matins: "Te decet laus" — done (2026-08-23)

Added as a new common text (data/propers/common/te-decet-laus.yml, sourced from Psalterium/Common/Prayers.txt's [Te decet] block) rendered as a versicle part immediately after the Te Deum on every 3-nocturn day (Sunday or Duplex+), in both hours/matins.ts branches that push a Te Deum. Absent on ferial (1-nocturn) days, same gating as the Te Deum itself. tests/hours/matins.test.ts covers both the Sunday branch's presence/content and the ferial branch's absence.

Lauds/Vespers ferial Preces psalms dropped — done (2026-08-23)

Psalm 129 (De profundis) and its own trailing Gloria Patri deleted wholesale from data/propers/common/lauds-preces-feriales.yml's text.la/text.en; Psalm 50 (Miserere) and its own Gloria Patri likewise from vespers-preces-feriales.yml. Surrounding V/R litany needed no adjustment — the psalm block sat between two already-independent V/R sequences. Both files' header comments updated to flag the drop as deliberate, not a transcription gap. tests/hours/lauds.test.ts and vespers.test.ts updated to distinguish the fuller ferial Preces from the short Sunday/feast litany via a versicle that survives the psalm's removal ("Ego dixi: Dómine, miserére mei") instead of the now-absent psalm text.

Matins psalmody overrides for a Duplex+ weekday feast — all categories done (2026-08-27/28)

All nineteen Common categories now authored, across four passes (see "Matins psalmody overrides — nine more categories", "— second pass, four more categories", "— third pass, source-file-first method", and "— fourth pass, Widow and Several Women Martyrs closed via secular sourcing" elsewhere in this file): Martyr, Apostle (+ aliases Apostles-plural and Evangelist), Confessor (+ aliases Abbot, Confessor-not-Bishop, and Several-Confessors), Confessor-Bishop (+ aliases Confessor-Doctor and Confessor-Pope), Several Martyrs, Virgin-Martyr (+ alias Virgin, plain), the BVM, a Dedication, a Holy Woman, and — closed in the fourth pass, 2026-08-28, by explicit user authorization to use secular-track content directly — a Widow (+ alias Several Women Martyrs). Plus, separately, all 5 angel feasts and St. Scholastica (Virgin) have their own saint-level proper Matins psalmody authored directly (same shape as st-andrew.yml/st-lawrence.yml), each a case where the saint's own [Rank] cites a Common but their real content is genuinely proper.

Methodology arc across the four passes: live-CGI trial-and-error across candidate saints/years (passes 1-2) → reading the reference engine's own CommuneM/*.txt/Commune/*.txt template source files directly, one targeted live query per finding to confirm (pass 3, much faster, directly disproved two of pass 2's own claims) → combining direct source-reading of the Monastic substitution rule with a live SECULAR-track query to supply the actual text, once explicitly authorized that secular sourcing needs no special justification beyond this project's own established blended-track design (pass 4, see that section for the Widow/Several-Women-Martyrs resolution in full). No categories remain open.

Commemoratio Octavæ blocks + fixed Lord's/BVM feast exclusions — closed (2026-08)

The four "Commemoratio Octavæ" Ant+V/R+collect blocks (Christmas Octave's own Nativity/Stephen/John/Holy-Innocents commemorations, e.g. on Dec 30) are done — see "Octave content" elsewhere in this file. St. Frances of Rome's/St. Bibiana's Benedictus antiphons and Ss. Ursula and Companions' were also once flagged here — the first two turned out already resolved (verified live, see memory vu-todo-priority's own correction note), the third is a settled non-gap (no unique text exists to author, see her own file's comment) — not carried forward as open items.

Five "fixed Lord's/BVM feast, not modeled" exclusions across the calendar (Our Lady of the Snows, the Finding of the Holy Cross, the Transfiguration, the Exaltation of the Holy Cross, the Dedication of the Lateran, the Presentation of the BVM) turned out to be the same stale mistake repeated six times — all six now added with real content; see "Our Lady of the Snows added" and "Four more 'not modeled' fixed Lord's/BVM feasts added" elsewhere in this file.

Lauds/Vespers chapter/responsory/hymn/versicle bundle — done (2026-08-26)

Mechanism is rank-agnostic (any sanctoral winner falls back to their Common, not just duplex-majus+); all 11 Common categories now have a real, live-verified bundle authored (see the dated log entries elsewhere in this file, e.g. "Common-of-Several-Confessors Lauds/Vespers bundle authored — last Common category closed"), plus the individual proper-content fixes swept up alongside it (Guardian Angels/Archangels reuse, Finding/Exaltation of the Holy Cross, Transfiguration, All Saints of the Benedictine Order). The same session also closed the separate resolveMatinsHymn fallback chain's equivalent gap for every category/saint this pass touched (see "Matins hymn gap closed for the same categories/saints" elsewhere in this file) — Matins hymns are a different mechanism from the Lauds/Vespers bundle and needed their own pass.

Gospel pericope + paired homily rendered as one part — done (2026-08-28)

Closed the last open Matins mechanism gap. ResolvedPart gained its own 'gospel' kind (src/hours/types.ts), replacing the old lesson+isGospel flag entirely — a Gospel pericope now carries an optional nested homily ({ source?, text }) instead of being a same-kind sibling lesson part next to it.

The reason for nesting rather than keeping two adjacent pool entries: distributeIntoNocturns's front-light 1/1/rest slicing (see "Reading distribution" elsewhere in this file) splits the reading pool by raw index, with no notion that two adjacent entries belong together — a Gospel pericope and its own homily, sourced as two separate array entries in data/propers/nocturn-readings/*.yml, could land in different nocturns purely by where they fell in the pool. Fixed at the pool-assembly step instead of patching the slicer: buildReadingPool (src/hours/matins.ts) now detects an isGospel: true NocturnReading immediately followed by a same-nocturn isGospel: false one and folds the pair into a single gospel pool entry before it ever reaches distributeIntoNocturns — the pairing is structural (one array element), not a convention the slicer has to know about. A bible-plan Gospel reading (never paired with a homily, per the user's own plan) becomes a bare gospel part with no homily, so it still gets the same "Gospel" UI treatment.

One real data wrinkle surfaced, not touched: chair-of-st-peter-at-rome.yml's Nocturn 3 has the homily prose already folded into the same isGospel: true entry's own text (an earlier, less clean authoring convention flagged in this file's own SanctiM-pass notes) rather than as a separate following reading — that file is left as-is per the earlier decision not to "fix" it; the new 'gospel' type's source field (distinct from homily) exists specifically to carry that entry's own attribution without misrepresenting it as a separate homily reading.

hour-view.ts renders the pericope with a "Gospel" heading, then the nested homily (when present) directly underneath in the same section, visually set off by a top border (.ordo-part-homily in styles.css) — one section, pericope then homily, rather than two separate ordo-part blocks that could be visually or structurally pulled apart. tests/hours/matins.test.ts's Sunday proof (2026-09-06, Luke 7:11-16 + St. Augustine's homily) updated to assert against the new gospel/homily shape instead of two isGospel-flagged lessons. npm test/npm run build both pass.

Vespers ferial psalmody weekday bug — fixed (2026-08-28)

Vespers psalms on Monday-Saturday were silently following the anticipated (First-Vespers) day's weekday instead of the actual calendar date's weekday, on any evening where tomorrow claimed First Vespers (hasFirstVespers has no rank floor, so this fired on most such evenings). Root cause: hours/vespers.ts's resolvePsalmody reused resolveEveningDay's result — correct for propers/office (chapter/responsory/hymn/versicle/collects/Magnificat antiphon), which legitimately borrow tomorrow's identity — but the ferial psalm-distribution table has no per-feast override of its own, so it needs today's own place in the fixed 6-day cycle regardless of whose office governs the evening. Fixed by computing weekdayOf(date) (the actual calendar weekday, calendar/weekday.ts) separately in resolveOrdo and threading it through as its own parameter, used only for the psalm-table lookup; resolveOffice's ferial-bundle fallback correctly keeps using the governing (possibly-anticipated) day's weekday, since that IS a legitimate per-office-bundle rule. Regression test: tests/hours/vespers.test.ts, 2026-08-25 (Tuesday anticipating St. Zephyrinus's Aug 26 First Vespers) — expects Tuesday's psalm group [129, 130, 131, 132], not Wednesday's. npm test/npm run build both pass.

Lauds/Vespers duplex-majus+ Common-category psalmody — mechanism built, 8 categories authored (2026-08-28)

Prompted by a design question: does it make sense to gate a Vespers psalm override at duplex-majus+, the same threshold Matins already uses? Checked against the live reference engine rather than assuming, and found two real, previously-undiscovered facts:

• Lauds already has this override (getPsalmodyOverrideFor, duplex-majus+-gated), but only a per-feast tier (lauds-psalmody-overrides/*.yml) — no per-Common fallback, so most duplex-majus+ saints without their own authored proper fell straight through to the plain ferial default even though the real rubric calls for an override. Confirmed live (votive=C1..C11) that Lauds' override psalm numbers (92, 99, 62, Canticum Trium Puerorum) are identical across every Common — only the antiphons vary — matching the existing per-feast overrides' own doc comments (e.g. st-lawrence.yml's note that its numbers "happen to be the same 92/99/62... that most Common-of-Martyrs-shaped feasts reuse").
• Vespers had no psalmody-override mechanism at all (flagged honestly in its own doc comments as a known gap) — and unlike Lauds, its override psalm numbers themselves differ by Common (Common-of-an-Apostle: 109/112/115/138; Common-of-a-Confessor-Bishop: 109/111/112/131; etc.), confirmed live the same way.

Mechanism, mirroring matins-psalmody-overrides.ts's existing saint/category two-tier precedent: hours/lauds-psalmody-overrides.ts gained a categories tier (data/hours/ lauds-psalmody-overrides/categories/*.yml, keyed by SaintRecord.common with optional aliases) consulted after the existing per-feast tier — getLaudsPsalmodyOverride now does getLaudsSaintOverride(id) ?? getLaudsCommonOverride(id), so hours/lauds.ts needed no changes at all. hours/vespers-psalmody-overrides.ts is a new file built from scratch with the identical saint/category shape (the saint tier is mechanism-only, zero files yet), wired into hours/vespers.ts's resolvePsalmody via the same getOfficeOverrideId eligibility test resolveOfficeBundle already uses for the chapter/hymn bundle — eligibility follows the evening's governing day (so a First Vespers of a majus+ feast gets that feast's own psalms, same as it gets that feast's own office), while the plain-ferial-fallback path still uses the actual calendar weekday (see the bug fix above).

8 of 24 SaintRecord.common categories authored for both hours (16 ids via aliases), each live-verified against Divinum Officium (Monastic Tridentinum 1617, votive=C1/C2/C3/C4/ C5/C6/C7/C11, 2026-08-28): common-of-an-apostle (+common-of-apostles), common-of-a-martyr (+common-of-a-martyr-bishop), common-of-several-martyrs, common-of-a-confessor-bishop (+common-of-a-confessor-doctor), common-of-a-confessor-not-bishop (+common-of-a-confessor, common-of-an-abbot, common-of-several-confessors), common-of-a-virgin (+common-of-a-virgin-martyr), common-of-a-holy-woman (+common-of-a-widow), common-of-the-bvm. Remaining 5 categories (common-of-a-dedication, common-of-an-angel, common-of-an-evangelist, common-of-a-vigil, common-of-several-women-martyrs) have no confirmed votive code yet — see "Lauds/Vespers duplex-majus+ Common-category psalmody" in the Open-work list above.

Regression tests added to both tests/hours/lauds.test.ts and tests/hours/vespers.test.ts: a real category-tier date per hour (Our Lady of Mount Carmel/St. Benedict/Ss. Placid and Companions for Lauds; St. Bartholomew/St. Lawrence's octave/St. Martin of Tours's First Vespers for Vespers — several needed a different date than their existing office-bundle tests once the actual governing evening was traced through resolveEveningDay/octave substitution), plus one below-threshold (Semiduplex/Duplex) negative case per hour confirming the plain ferial default still wins there. One pre-existing Vespers test (2026-08-17, "joins Ps 115 and 116... on Monday") had to move to a different date: that Monday turned out to be the closing day of St. Lawrence's own octave, which now correctly picks up Common-of-a-Martyr's psalms instead of the plain ferial set it was (incidentally, not intentionally) relying on before this mechanism existed. npm test (535 passed) and npm run build both pass.

Lauds/Vespers duplex-majus+ Common-category psalmody — remaining categories authored, one real gap surfaced (2026-08-28)

Follow-up to the previous entry, closing most of the "8 of 24" gap it left open. Went category by category through the reference engine's votive-code space (the full CommuneM/ directory listing, C1 through C12 and their season-variant suffixes) to identify each remaining SaintRecord.common value's real scheme, rather than assuming one exists:

• common-of-an-evangelist is an alias, not its own scheme. St. Mark's and St. Luke's own reference-engine rule files both say "ex C1a", and votive=C1a returned byte-identical Lauds/Vespers psalmody to plain votive=C1 — an Evangelist-not-Apostle genuinely reuses the Apostles' own scheme in the Monastic tradition. Registered as an alias on common-of-an-apostle's existing category files for both hours.
• common-of-several-women-martyrs is also an alias, not its own scheme — but only once the actual Vespers/Lauds psalmody slots are isolated from the Magnificat/Benedictus antiphon that follows them. Ss. Perpetua and Felicity's own file says "vide C7b"; votive=C7b returned the same four psalm numbers and group/canticle/Laudate antiphons as plain votive=C7 (Common-of-a-Holy-Woman) for both hours — C7b's only real difference is its own proper Magnificat/Benedictus antiphon, which belongs to a separate, already-existing mechanism (getMagnificatAntiphon/getBenedictusAntiphon), not the psalmody-override table this pass is building. First-draft category files for this id were written as full duplicates before this was caught by diffing against the live output line-by-line — deleted in favor of an alias on common-of-a-holy-woman's existing files instead. Neither this id nor common-of-a-vigil (see below) can currently be exercised via resolveOrdo/a real calendar date (Perpetua and Felicity are plain Duplex, below this override's threshold, and no other saint carries this Common) — verified via a direct getLaudsCommonOverride/ getVespersCommonOverride unit test instead of a date-based one.
• common-of-an-angel has no real numbered Common in the source at all — confirmed via the full CommuneM/ directory listing (no angel-specific code exists) and St. Michael's own SanctiM rule, which says plain "Psalmi Dominica" (Sunday's own Vespers psalm numbers, 109-112, not a Common-specific set) rather than citing any Cx file. Live-verified that Guardian Angels (Oct 2, Duplex Majus, no proper text of her own) reuses Michael's own antiphons byte-for-byte at both Lauds and Vespers — i.e. Michael's own proper is the de facto generic Angel scheme any other Angel-Common saint without their own proper falls back to. (St. Gabriel and St. Raphael each have their own genuinely distinct proper antiphons, matching this file's own earlier finding for the office bundle that Guardian Angels/Gabriel/Raphael's chapter/responsory/hymn/versicle content is duplicated per-saint from St. Michael's Apparition, not drawn from a shared Common — the same absence of a real Angel Common, independently confirmed for a different content type.) Authored as a genuine common-of-an-angel category (an app-side generalization the source data doesn't literally have a file for, but a real, reusable scheme in practice) rather than duplicating Michael's antiphons into a Guardian-Angels-specific file, so any future proper-less Angel addition benefits automatically. Lauds keeps the usual fixed 92/99/62 + Canticum Trium Puerorum numbers; Vespers substitutes "Psalmi Dominica" (109-112) instead of a Common-specific set.
• common-of-a-dedication is genuinely its own scheme (votive=C8) for both hours — unlike every other Common authored so far, Vespers' numbers (109/110/111/147) don't share a pattern with any other category, and Lauds' (50/87/89 + "Canticum Ieremiæ") aren't even the usual fixed 92/99/62 set. Only the Vespers file was authored: Lauds' own canticle text has never been transcribed anywhere in this app (the 7 existing Lauds OT canticles, hours/ lauds-canticles.ts, are only the plain weekday rotation) — left open rather than guessed at, see the Open-work list above.
• common-of-a-vigil is not an authorable gap at all. The vigil FeastClass sits structurally below duplex-majus on calendar/commemorations.ts's FEAST_CLASS_ORDER ladder, so getOfficeOverrideId's isAtLeast(winner.rank, 'duplex-majus') test can never return true for a Vigil — this category is permanently unreachable by the mechanism as gated, not a missing-content gap to close later.

Regression tests added to both lauds.test.ts and vespers.test.ts: a real calendar date for each reachable category (Guardian Angels for Angel, both hours; the Dedication's own day for Vespers), a real date via the alias for common-of-an-evangelist on Vespers (St. Mark, whose own per-feast Lauds override shadows the category tier for Lauds specifically, so that one used a direct unit test instead), and direct unit tests for the two currently-unreachable-by-date aliases (common-of-several-women-martyrs for both hours). Two more pre-existing Vespers test dates needed to move for the same reason as the previous entry's 2026-08-17 fix: 2026-09-28 (anticipates St. Michael's own First Vespers, once his Common-of-an-Angel override started applying) moved to 2026-10-12; Guardian Angels' own initial test date (Oct 2, her own day) had to move to Oct 1 (her First Vespers) once tracing resolveEveningDay showed she doesn't keep her own Second Vespers (falls short of the duplex-2-classis floor) and Oct 3 (St. Therese, plain Duplex, below this override's own threshold) claims her evening instead. npm test (542 passed), tsc --noEmit, and npm run build all pass.

Compline Preces on a Double no longer vanish entirely — done (2026-08-28)

User request: incorporate the secular track's Compline Preces, but always keep a short litany + Our Father said, even on a Double. Checked first rather than assuming a text change was needed: compline-preces.yml's content is already word-for-word the secular Tridentine 1906/1910 text (the reference engine treats "1888/1906/1910" as one combined version label, same rubrics) — it was already the fuller, non-Monastic form, live-verified against both tracks. The real gap was structural: compline.ts's 'preces' case dropped the whole part to [] on a Double-or-higher (omitOnDouble), matching real practice in both Monastic and secular tracks (Compline's Preces are never substituted with anything shorter in the reference engine, secular or not — unlike Vespers/Lauds, which do fall back to a short litany).

Per the user's explicit request, this is now a deliberate vu-specific deviation from both tracks: compline.ts's 'preces' case substitutes lauds-short-litany (the same short Kyrie/Pater-Noster litany Vespers' own vespers-preces case already falls back to on Sundays/ feasts) instead of omitting, whenever omitOnDouble and isDoubleOrHigher both hold. types.ts's omitOnDouble doc comment and compline.yml's own header updated to describe the substitution rather than a drop. Regression test added (tests/hours/compline.test.ts, 2026-08-15, the Assumption, Duplex I. classis) confirming the short-form text (Kyrie/Pater/"Dómine, exáudi") is present and the fuller exchanges ("Benedíctus es, Dómine.../Miserére nostri...") are absent. npm test (543 passed), tsc --noEmit, and npm run build all pass.

Vespers Magnificat antiphon — whole-calendar temporal-cycle gap closed, 52/54 (2026-08-30)

User flagged 2026-08-29's Vespers was missing its Magnificat antiphon. Root cause turned out to be systematic, not date-specific: getMagnificatAntiphon (hours/resolve-common.ts) looks up ${winner.id}-magnificat-antiphon for a temporal winner, but of the 57 temporal ids with an authored Lauds -benedictus-antiphon.yml, only 3 (holy-name-of-jesus, immaculate-heart-of-mary, circumcision) had a matching Vespers -magnificat-antiphon.yml — every ordinary Sunday/named-feast in the temporal cycle (all 24 post-pentecost-NN weeks, Advent, post-Epiphany, pre-Lent, Lent, Passion/Palm Sunday, the whole Easter season, Pentecost, Christmas-octave Sunday, Christ the King) had its Lauds antiphon but not its Vespers one, apparently missed whenever the Lauds sweep pulled [Ant 2] from the reference engine's Tempora files but never followed up with [Ant 3].

Sourced from the same static reference-engine files already used for the Benedictus sweep (../divinum-officium-reference/web/www/horas/{Latin,English}/Tempora/*.txt), same occasion/date as each id's own -benedictus-antiphon.yml sibling (its header comment already records the clean verified date) — no live CGI needed, the Magnificat antiphon is baked into each static file's own [Ant 3] block (sometimes an alias, e.g. @:Ant 3_ or @:Ant 1, always resolved to its real text before use, and always the default/Tridentine variant, never a (rubrica cisterciensis...) one). post-pentecost-01..23 map straight to Tempora/PentNN-0.txt; post-pentecost-24 (the fixed last Sunday) does not map to Pent24-0 — cross-checked against its own already-authored Benedictus antiphon and confirmed it actually reuses the leftover post-epiphany-6 formulary (Tempora/Epi6-0.txt), the classic "Sundays remaining over are supplied by the omitted post-Epiphany Sundays" rubric, already implicit in this app's own resumed-Epiphany-Sunday overflow logic. post-epiphany-1 doesn't map to Epi1-0.txt (that file is Holy Family Sunday content in the reference engine, a title mismatch against the already-authored Benedictus text) but to Epi1-0a.txt ("Dominica infra Octavam Epiphaniæ"). christ-the-king (not a Tempora entry at all, a 1925 addition) sourced from Sancti/10-DU.txt instead, matching its own Benedictus antiphon's already-verified occasion.

Two ids skipped, not fabricated: advent-4 (Tempora/Adv4-0.txt has no standalone [Ant 3] at all — only [Ant Vespera 3] @:Ant Laudes, aliasing the whole 5-antiphon Lauds set rather than one text, and which single entry the live engine actually picks isn't determinable from the static file alone) and marian-saturday (the votive "Sanctæ Mariæ Sabbato" office's Magnificat antiphon isn't in any static Tempora/Sancti/Commune file found — likely only resolvable via a live CGI query, same as how its own Benedictus antiphon was originally sourced).

O Antiphons (Dec 17-23) added — advent-4's own gap effectively closed (2026-08-30)

Follow-up the same day, prompted by a user report that 2026-08-29's own Vespers was missing its Magnificat antiphon entirely for an unrelated reason (see the day-label winner-first fix earlier this date) that turned out to expose this whole-calendar gap. Root cause of advent-4's own skip above, once actually investigated live (divinumofficium.com, Monastic Tridentinum 1617): Dec 17-23 always carries one of the seven "O Antiphons" at Vespers, keyed to the calendar date itself, not to whichever Advent week (advent-3 or advent-4, depending on the year) happens to govern that date — a single per-week static file was structurally the wrong shape for this from the start, not just missing content.

Added data/hours/vespers-o-antiphons.yml (7 entries, MM-DD keyed) and a new lookup tier in hours/resolve-common.ts's getMagnificatAntiphon. 5 of the 7 (Dec 17/18/19/22/23) live-verified directly. The remaining two — "O Clavis David" (Dec 20) and "O Oriens" (Dec 21) — could not be: every version/track on the live engine (including plain Tridentine 1570) routes those two dates through St. Thomas's Vigil/feast instead of the ferial Proper of the Time, apparently a real modeling choice of that engine (a Vigil of an Apostle actually displacing the ferial Magnificat antiphon), not an app quirk — and this app's own vigil-of-st-thomas.yml already documents a deliberate divergence from exactly that engine behavior on this date (the Vigil transfers away entirely here, per the ordinary privileged-feria/vigil rule). Marked draft rather than verified: real, standard, universally-fixed O-Antiphon wording (unchanged across every edition of the Roman/Monastic Breviary), just not confirmed against this app's own primary live reference for lack of a clean query path — see the data file's own header.

Follow-up the same day, direct user instruction: the O Antiphon lookup was originally scoped to only apply when the day's winner was still plain-temporal (i.e. it deferred to a real sanctoral winner, same as every other tier in getMagnificatAntiphon). The user explicitly wanted the O Antiphons to actually surface even against a real winning saint — St. Thomas (Dec 21, Duplex II. classis) otherwise wins that day outright with no Magnificat antiphon of his own authored yet (a separate, pre-existing gap — no sanctoral saint has a ${propers}-magnificat-antiphon.yml at all), so "O Oriens" was structurally unreachable on its own real date. Considered and rejected: lowering Thomas's rank so a ferial default would win Dec 20/21 instead — factually wrong (he really is Duplex II Class pre-1955) and would strip him of his entire office (chapter/hymn/collect/Lauds antiphon too), not just Vespers' Magnificat. Instead, moved the O-Antiphon lookup to the very top of getMagnificatAntiphon, checked unconditionally before either the temporal or sanctoral branch — the O Antiphon now wins this one specific text slot on Dec 17-23 full stop, regardless of who otherwise wins the day; every other part of the office is untouched. Deliberate, explicit app-level design choice (not a reconstruction of the reference engine's own Dec 20/21 behavior, which shows Thomas's own antiphon there instead) — see the data file's own header for the reasoning, including why a saint's own real Magnificat antiphon is still worth authoring later even knowing it would be permanently unreachable at Vespers on whichever of these seven dates that saint occupies, under this calendar's own construction: the user has a future user-editable calendar in mind, where a differently-constructed calendar's own precedence might surface it. tests/hours/vespers.test.ts's Thomas-precedence case now asserts the opposite of its original intent (the O Antiphon wins, his other office parts don't).

Net effect: advent-4's practical gap is closed for every date this app's calendar can actually reach — Dec 17-23 unconditionally now, including Dec 21 itself. One narrow residual sub-case remains, not touched by this fix: if Advent 4's own Sunday itself lands on Dec 24 (the latest possible date, outside the O-Antiphon range and excluded from the classic weekday-default fallback since Sunday has none), it still resolves to missing — genuinely no source for that one specific Sunday found yet. marian-saturday is unchanged by this pass (still skipped, per above) — and turns out to be moot for Vespers specifically anyway: its own evening is never actually reachable through resolveOrdo, since a following Sunday always claims First Vespers over the preceding Saturday regardless of the Sunday's own rank (calendar/vespers.ts's hasFirstVespers).

New tests: tests/hours/vespers.test.ts's "O Antiphons (Dec 17-23)" block (the Dec 19 case end-to-end, plus the Thomas-precedence case); tests/hours/resolve-common.test.ts's new getMagnificatAntiphon — classic weekday-default fallback block replaces the old bare-ferial resolveOrdo test with two synthetic-day unit tests instead, since no live date is left in this app's calendar that still reaches that fallback tier through the real pipeline at all (every other temporal id now has its own real content, per this whole sweep). npm test (556 tests) and tsc --noEmit both pass; live-verified on the dev server (2026-08-29 and 2026-12-19).

52 new src/data/propers/temporal/*-magnificat-antiphon.yml files. npm test (553 passed) and tsc --noEmit both pass; spot-checked live in the dev server that 2026-08-29's Vespers now shows the Magnificat antiphon ("Quǽrite primum * regnum Dei et justítiam ejus...", post-pentecost-14's own).

The Vigil of Christmas given its own real content (2026-08-30)

User report: "let's fix the problem with advent iv and 12/24 colliding." Dec 24 previously had no content of its own at all — a plain (non-Sunday) Dec 24 just inherited Advent 4's ferial collect and antiphons, and when Advent 4's own Sunday landed on Dec 24 (its latest possible date), the app gave Advent 4 the day outright with zero trace of the Vigil, no commemoration, nothing.

Checked the reference engine directly (SanctiM/12-24.txt/12-24s.txt) rather than guess at the rubric: the Vigil is Duplex I classis, never displaced even by a privileged Sunday, but keeps Advent 4's own psalms and first two Matins nocturns' lessons — a genuine content splice, not a "who wins" contest, with the source explicitly noting no commemoratio for the Sunday case. Imported real Vigil content: vigil-of-christmas-collect.yml, 5 Lauds antiphons (lauds-psalmody-overrides/vigil-of-christmas.yml), the Benedictus antiphon (live-verified, 2026-12-24 — turned out to just reuse the same Matins Nocturn-2 antiphon text), and the Matins Gospel (Matt 1:18-21) + St. Jerome homily (nocturn-readings/vigil-of-christmas.yml). Wired via a new vigil-of-christmas temporal id (calendar/temporal-id.ts), applied to Dec 24 unconditionally regardless of weekday.

Departure from the reference by direct instruction: unlike the source's own no commemoratio, Advent 4 is still commemorated here when it's the Sunday landing on Dec 24 — the Sundays of Advent have real standing of their own. applyAdventFourVigilCommemoration (calendar/index.ts) pushes advent-4 as an explicit commemoration on that one date. Matins' three-nocturn Sunday psalmody needed no change — it's driven by weekday, not by which id wins, so Advent 4's own psalms/lessons pattern survives automatically.

New tests: tests/calendar/vigil-of-christmas-sunday.test.ts (4 cases, both the winner/ commemoration shape and Lauds/Matins content). npm test (560→774 across this and the following entries) and tsc --noEmit pass throughout.

Sanctoral commemoration antiphon+versicle bundles — full 218/218 (2026-08-30)

User report, same day: "today's Vespers is missing the antiphon for Commemoration of St. Raymond Nonnatus" — then, before a fix landed, a second live report: "no antiphon for Commemoration of The Beheading of St. John the Baptist," and a third the day before (Ss. Felix and Adauctus, at Lauds). Investigating found the real scope: 217 of 220 saints with an authored collect had no ${propers}-commemoration.yml bundle at all — sanctoralCommemorationPart (hours/resolve-common.ts) was silently falling back to a bare collect (still status: verified, since the collect itself is fine, so nothing flagged it as broken) whenever that saint was merely commemorated rather than winning outright. Only Clare, Sabina, and Jane Frances de Chantal had one.

Fixed the three reported saints first, live-verified. Cross-checking those three found the correct source tags: the real commemoration antiphon+versicle in the reference engine's Commune files is [Ant 2] + [Versum 2] — not [Ant 1] (the saint's own main Lauds antiphon slot, wrongly assumed at first for St. Raymond Nonnatus, later corrected) and not [Nocturn 2 Versum] (a different, Matins-only tag). Also found individual saints can deviate from their own nominal common: category (St. Sabina, tagged common-of-a-martyr, actually uses the Holy-Woman/Widow antiphon "Date ei de fructu") — raised as a scale-of-effort question, which the user answered directly: "check each saint in vu. if there's no commemoration antiphon, check the reference source. if there's a proper there, use it. if there's not, use the commons. it's literally that easy" (see memory vu-feedback-dont-overthink-scale).

Bulk pass followed that rule exactly: reused each saint's own proper antiphon where authored (${propers}-antiphon.yml) paired with their Common category's [Versum 2], else the category's own [Ant 2]+[Versum 2] verbatim. 100 saints with an existing antiphon done first (mechanical — just needed the right versicle per category), then 73 more using the category's own generic antiphon for saints with no proper text of their own. A same-day follow-up pass sourced the remaining categories: BVM (13, via Commune C11, reusing the already-verified BVM suffrage versicle), angels (4, versicle inferred from a saint file's own "vide C4, structural category only" note), Confessor-Doctor/-Pope (7, resolved to C4a/C5a/C4b — each inheriting its base category's Ant2/Versum2 with no override needed), several confessors + apostles-plural (2), and 5 fully-proper Lord's/BVM feasts given their own real [Ant 2]/[Versum 2] straight from their Sancti files. 213 of ~218 real saints covered at that point (tests/propers/commemoration-sweep.test.ts, 213 cases); every entry not independently live-verified marked status: draft.

The last 5 (the Vigils, common-of-a-vigil) looked unsourceable at first — no dedicated "Commune Vigiliarum" antiphon set exists in the reference engine. The user pushed back explicitly ("are you sure -- what happens if you pull the reference engine?") rather than accept that at face value. Live-querying real commemorated instances (Vigil of St. Lawrence on a real Monday, Vigil of the Assumption across 6 different real weekdays) found the actual mechanism behind each source file's own [Rule]: Versum Feria line: a mere commemoration doesn't reuse the vigil's own antiphon at all — it borrows the plain ferial day's antiphon/versicle instead. The antiphon quotes the Benedictus canticle in weekday sequence (same shape vespers-magnificat-antiphons.yml already uses for the Magnificat), the versicle is a single fixed text (lauds-versicle-monday.yml's own), and Sunday genuinely has no entry — a Vigil transfers off an ordinary Sunday rather than ever reaching a commemoration there, confirmed live and already true in this app's own precedence rules. Implemented as a small weekday-aware branch in sanctoralCommemorationPart (now takes weekday) rather than a per-saint file.

Full 218/218. New/changed tests: tests/propers/commemoration-sweep.test.ts (213 static bundles), tests/hours/vigil-commemoration.test.ts (3 cases, the dynamic weekday mechanism), tests/hours/lauds.test.ts's new Felix/Adauctus case. 176 new *-commemoration.yml files plus one data file (lauds-vigil-commemoration-antiphons.yml). npm test (774 passed) and tsc --noEmit pass.

Vespers Magnificat antiphon — the last two cases closed as not gaps (2026-08-30)

Follow-up the same day: asked what the two remaining Magnificat gaps from the entry above actually were (Advent 4's own Sunday landing on Dec 24; marian-saturday), then pushed back on "there's nothing authored, but do you need to author content that never happens?" — a fair question the TODO list hadn't actually answered. Checked both directly rather than leave them as "unauthored, low priority": the Vigil of Christmas never has its own Vespers in the real rite at all (Dec 23 evening is plain Advent-4 ferial Vespers with the O-Antiphon override, not First Vespers of the Vigil — checked live; Dec 24 evening is always Christmas's own First Vespers — "Vespera de sequenti; nihil de præcedenti," the reference engine's own words), and marian-saturday's own Commune file (C10) has no [Ant Vespera] tag at all, because a Saturday's Vespers is always structurally ceded to the following Sunday under the real rubrics, not just under this app's implementation of them.

Neither is "unauthored content pending" — there is no historical text for either case to author. Dropped from the "Open work" list entirely rather than marked done-with-a-caveat, since authoring something anyway would mean inventing text that never existed.

Bilingual header nameLa mechanism (2026-08-31)

Picked up the standing "Latin saint/octave/named-feast names" backlog item. The Bi ({en, la}) display wrapper already existed in calendar/day-label.ts, but the underlying data had no bilingual name field at all — SaintRecord.name, TemporalFeastRecord.name, and the derived SanctoralIdentity/ActiveOctave/Commemoration types were plain English strings, so every proper name necessarily fell back through biFallback.

Added an optional nameLa?: string alongside name on SanctoralIdentity (calendar/types.ts), SaintRecord/SanctoralCandidate (calendar/feasts.ts), TemporalFeastRecord (calendar/temporal-feasts.ts), and ActiveOctave (calendar/octaves.ts), then threaded it through every construction site that had been spreading id/name/rank (collision.ts, commemorations.ts, movable-feasts.ts, index.ts x3, vespers.ts x2, octaves.ts's considerCandidate). day-label.ts's old biFallback(name) calls became biName(name, nameLa), which still falls back to the English string when nameLa is absent — the "surface real text, don't block on missing" convention preserved exactly, just now backed by a real field instead of no field at all.

Authored nameLa for all 11 named temporal feasts as the proof set (each sourced from the reference engine's own [Officium]/[Rank] title, adapted from the source's genitive/ablative liturgical-title style to this app's nominative-noun-phrase naming convention — e.g. "In Ascensione Domini" → Ascensio Domini, "Sacratissimi Cordis Domini Nostri Jesu Christi" → Sacratissimum Cor Domini Nostri Jesu Christi) plus St. Lawrence as the one saint, chosen specifically to exercise the octave-headline (octaveCoreName) and octave-commemoration code paths, not just the plain-winner path the temporal feasts alone would have covered. Live-verified end-to-end via a throwaway scratch test (removed after confirming) that Pentecost's/the Ascension's/the Immaculate Heart's own winner label, St. Lawrence's mid-octave and closing-day octave label, and his octave commemoration line (Aug 12) all render the authored Latin, not the English fallback. Six pre-existing toEqual test fixtures across august-sanctoral.test.ts, octaves.test.ts, transfer.test.ts, and december-sanctoral.test.ts needed their expected objects updated to include the new nameLa key (Christmas's own octave-commemoration entries too, since christmas-day.yml picked up a name in this same pass). npm test (807 passed) and tsc --noEmit pass.

Bulk pass, same day: authored nameLa for the remaining 299 real saints (every src/data/calendar/saints/*.yml except example-confessor, a deliberate non-real placeholder never wired into sanctoral-calendar.yml). Sourcing standard for this bulk pass was lighter than per-saint reference-engine verification (infeasible at this volume in one sitting): standard, well-attested ecclesiastical Latin forms — the saint's own canonical Latin name plus a Latin rendering of their English descriptor (Bishop → Episcopus, Martyr → Martyr, Virgin → Virgo, Confessor and Doctor of the Church → Confessor et Ecclesiæ Doctor, etc.), nominative noun phrase throughout, matching the temporal-feast proof set's own convention. Multi-saint feast names (e.g. ss-perpetua-and-felicity) got the equivalent Latin plural construction (Sanctæ ... Martyres). This is a different, lower sourcing bar than the rest of this app's content (which is reference-engine-verified line by line) — flagged here explicitly since a future pass may want to spot-check or upgrade individual entries against the reference engine's own titles, the way the 11 temporal feasts and St. Lawrence were.

Applied via a scratch Python script (nameLa inserted right after each name: line) plus two follow-up passes fixing ~180 pre-existing test fixtures across 18-20 test files that asserted exact toEqual objects on day.winner/day.commemorations (now carrying the new nameLa key). One real mechanism bug surfaced and fixed by this: calendar/index.ts's sanctoral-vs-sanctoral collision-resolution branch (resolveDay's per-day candidate loop, ~line 40) was rebuilding the winning candidate as { id, name, rank } without nameLa, silently dropping it for any saint that had beaten another candidate on the same date even when winning outright — caught by st-giles, st-justina, nativity-bvm, and vigil-of-st-lawrence all resolving nameLa: undefined despite having real authored data. Also found and fixed one stale test expectation (day-label.test.ts's Trinity Sunday/Queenship-of-the-BVM case) that had hardcoded "no Latin name yet" as the expected behavior — now asserts the real Latin. npm test (807 passed) and tsc --noEmit pass throughout. Closes this backlog item — moved out of the "Open work" priority list.

Vespers Magnificat antiphon — sanctoral Common-category fallback, 11/11 (2026-08-31)

User flagged today's (Aug 31, St. Raymond Nonnatus) Vespers was missing its Magnificat antiphon. Root cause was systemic, not date-specific — the earlier 2026-08-30 pass (see above) had closed the temporal-cycle gap in getMagnificatAntiphon, but the sanctoral Common-category fallback (magnificat-antiphon-${saint.benedictusCommon}) had never been authored at all: only 11 saints ever need it (the ones with propers: null or no own antiphon, falling back to benedictusCommon's 11 distinct category values), and every single one was missing.

Sourcing method: each Commune source file (Latin/Commune/C*.txt) lays out Vespers1([Ant 1]) -> Matins -> Lauds([Ant 2]) -> minor hours -> Vespers2([Ant 3]), confirmed directly by live query (Ss. Placid and Companions, 10-05-2026: the evening before renders [Ant 1] under "Vespera de sequenti", the feast's own evening renders [Ant 3]) and cross-checked against 3 more saints (St. Blaise, St. John Gualbert). Authored 10 of 11 categories' magnificat-antiphon-common-of-*.yml from each Common's own [Ant 3] (common-of-a-confessor/common-of-an-abbot share one file, C5, so their Magnificat text is identical by design, same as their existing Benedictus text).

Found and fixed two pre-existing bugs in sibling benedictus-antiphon-common-of-*.yml files while cross-checking [Ant 2] against them: common-of-a-confessor and common-of-the-bvm had both been sourced from [Ant 1] (First Vespers) instead of [Ant 2] (Lauds) — live-verified wrong via St. Alexius's real Lauds query (07-17-2026, renders "Euge, serve bone", not the file's old "Similabo eum"). Corrected both.

The 11th category, common-of-a-vigil, needed a code fix instead of a content file. Initially assumed unreachable (a Vigil's own Second Vespers always loses to the following feast's First Vespers — true, and confirmed via compareFeastClass('vigil', ...) always losing in resolveEveningDay). But a Vigil's own First Vespers (anticipated the evening before, since hasFirstVespers has no rank floor) absolutely does reach this code path — caught by re-checking after the user asked "what about 11 of 11?". Live-verified across 4 different years (2025-2028) that the real office never gives a Vigil a fixed proper Magnificat text at all — its [Rule] block ("ex C1v; ... Laudes 2") always borrows whatever the current ferial weekday's own antiphon is ({Antiphona ex Proprio de Tempore} every single year tried). So common-of-a-vigil correctly has no content file; instead getMagnificatAntiphon (hours/resolve-common.ts) now special-cases saint.rank === 'vigil' to fall through to the same vespersMagnificatAntiphons weekday-default table the plain temporal branch already used, before ever trying a Common lookup. npm test (810 passed) and tsc --noEmit pass.

Ferial Matins nocturn: one antiphon per psalm (2026-09-01)

User flagged that the ferial (1-nocturn) weekday antiphons looked inconsistent — some psalms paired under one shared antiphon, others solitary, within the same nocturn. Root cause: the source's own per-weekday tables (Daym1_-Daym6_) do frame several different-psalm pairs under one shared antiphon (normal Monastic practice), and vu's matins-ferial-antiphons.yml had carried that pairing straight through — reading fine in the source's own untouched weekly layout, but looking arbitrary once psalter-distribution.yml's reslice left some of those pairs intact and split others across weekday boundaries. Fixed by splitting every cross-psalm pair into two single-psalm groups (a same-psalm split across a chapter boundary, e.g. Ps 36:1-26/ 36:27-40, is unaffected — that's still one antiphon per psalm).

For each split pair, whichever psalm the antiphon's own words actually quote (checked against src/data/psalms/*.yml, not assumed from position — several pairs listed the second psalm's own words under the first psalm's slot, e.g. Wednesday's "Quam bonus Israël Deus" pair, [71,72], is actually Ps 72's own opening, not 71's) keeps that antiphon; its former partner got a new one, per direct instruction: search the reference corpus for a real one before inventing. Sourcing that produced (6 of 10 real, 4 composed fresh — all directly quoting that psalm's own Vulgate text either way, the same convention every other antiphon in this corpus follows):

• Real, borrowed: Ps 39 and 71 from Tempora/Quad6-5 and Tempora/Quad6-4 (Holy Week ferial propers); Ps 55 from Tempora/Quad5-5 (Lenten Friday ferial); Ps 102 from Tempora/Pent01-4; Ps 107 from Tempora/Pent02-5 (post-Pentecost ferial propers); Ps 48 from the Roman secular ferial Matins table ([Day0]-[Day6], same file as the Monastic table, individually-antiphoned rather than paired — see vu_secular_source_ok).
• Composed fresh (no match found anywhere in the corpus): Ps 33, 43, 79, 83 — each from its own opening verse, in the same incipit style the rest of the corpus already uses.

tests/hours/matins.test.ts's ferial test updated (was asserting "antiphon only on each group's first psalm" — now every psalm in the nocturn has one). npm test (814 passed) and tsc --noEmit pass.

Not done in the same pass, confirmed as a separate real gap: Sunday Matins' Nocturn 3 "Allelúja, allelúja, allelúja" antiphon is wrong for Septuagesima-Passiontide — see this file's "Mechanism gaps" section above for the live-verified detail and the 9 antiphons already collected.

Sunday Matins Nocturn III seasonal override, Septuagesima-Palm Sunday (2026-09-01)

Fixed the gap flagged above. New data/hours/matins-sunday-nocturn3-overrides.yml, keyed by temporalId, plus hours/matins.ts's sundayNocturn3For (looked up with the temporalId resolveOrdo already computes, merged field-by-field over matins-sunday-antiphons.yml's base nocturn3 group — only the real Sunday branch uses it, not the Duplex+-weekday-feast branches, which stay saint/Common-specific as before).

Re-verifying live (one prayMatutinum query per Sunday of the 2026 cycle, Monastic Tridentinum 1617) turned up more than the antiphon-only change the earlier note assumed:

• Septuagesima, Sexagesima, Quinquagesima: antiphon only — canticles (Isa 33:2-10/33:13-18, Sir 36:14-19) and versicle ("Exaltáre Dómine in virtúte tua. / Cantábimus et psallémus virtútes tuas.") are the same as the plain-season default.
• Lent 1-4: a genuinely different set of 3 canticles (Jer 14:17-21, Lam 5:1-7,15-17,19-21, Ezek 36:24-28 — new data/scripture/jer-14.yml, lam-5.yml, ezek-36.yml, the first content under the lam book code) and a different versicle ("Scuto circúmdabit te véritas ejus. / Non timébis a timóre noctúrno."), on top of the antiphon.
• Passion Sunday, Palm Sunday: base canticles, but the versicle is "Ne perdas cum ímpiis, Deus, ánimam meam. / Et cum viris sánguinum vitam meam." — not "Exaltáre Dómine." The earlier note's placeholder Passion Sunday antiphon text ("Deus ádjuvat me...") was actually this versicle, not the antiphon; the real antiphon is "Ego glóriam meam non quæro: † est qui quærat, et júdicet." (John 8:50, that Sunday's own Gospel). Palm Sunday's full antiphon: "Hosánna fílio David: † benedíctus, qui venit in nómine Dómini, Rex Israël: † Hosánna in excélsis."

New regression tests in tests/hours/matins.test.ts cover all three shapes (antiphon-only, antiphon+canticles+versicle, antiphon+versicle-only). npm test (817 passed), tsc --noEmit, and npm run build all pass.

Advent Sunday Matins Nocturns I-III seasonal override (2026-09-01)

Follow-up, same day: the user asked whether Advent Sundays' own Nocturn III needed the same kind of fix. Live re-check (prayMatutinum, Monastic Tridentinum 1617, all 4 Advent Sundays of the 2026 cycle) found the answer is yes, and bigger than just Nocturn III — Advent's own seasonal antiphons apply to all three nocturns, not just Nocturn III, and identically across all 4 Sundays (no per-Sunday variation the way Septuagesima-Palm has).

• Nocturns I-II: psalm numbers unchanged (Ps 20-31), but every one of the 6 antiphons and both versicles are seasonal — none of which existed anywhere in the codebase before this fix (unlike Nocturn III, Nocturns I/II had no override mechanism at all; matins.ts used the plain-season matins-sunday-antiphons.yml base unconditionally).
• Nocturn III: swaps the plain-season 3-canticle set (Isa 33:2-10/33:13-18, Sir 36:14-19) for a wholly different one (Isa 40:10-17, 42:10-16, 49:7-13 — 3 new data/scripture/isa-{40,42,49}.yml files), under its own Marian antiphon ("Gábriel Ángelus locútus est Maríæ...") and versicle.

New data/hours/matins-sunday-advent-nocturn-overrides.yml — a single season-wide block (keyed by season, not per-Sunday temporalId, since all 4 Advent Sundays are identical) — plus hours/matins.ts's generalized sundayNocturnFor(nocturn, day, temporalId), which now checks Advent's season-wide override ahead of (Nocturn III only) the existing per-Sunday Septuagesima- Palm sundayNocturn3For lookup; Advent and Septuagesima-Palm never overlap so there's no precedence conflict between the two override tiers.

New regression test in tests/hours/matins.test.ts (Advent Sunday Nocturns I-III seasonal override) asserts all 4 Advent Sundays render identically. npm test (818 passed), tsc --noEmit, and npm run build all pass.

Paschaltide Sunday Matins Nocturns I-III seasonal override (2026-09-01)

Second follow-up, same day: does any other season need the same treatment? Live sweep of the reference source (Psalterium/Psalmi/Psalmi matutinum.txt) confirmed only 3 season-tagged blocks exist at all — [Daym0] (plain default), [Advm0] (Advent, done above), [Paschm0] (Paschaltide) — so Christmastide and post-Epiphany Sundays have no gap; Paschaltide does.

Ordinary Paschaltide Sundays (Low Sunday through the Sunday before Ascension — day.season === 'eastertide') get the same seasonal antiphon/versicle/canticle treatment as Advent, live- verified identical across 5 Sundays of the 2026 cycle (04-12 through 05-10). New Nocturn III canticles: Isa 63:1-5, Osee 6:1-6, Sophonias 3:8-13 (3 new scripture files — first content under the osee/soph book codes). Structurally different from Advent's own shape, not just different text: Nocturns I and II each take a single antiphon covering all 6 psalms of the nocturn, not 3 separate antiphons (one per psalm-pair) — confirmed by the live query showing only one antiphon before/after each whole nocturn's psalmody. Nocturn III's own antiphon is unchanged from the plain-season "Allelúja, allelúja, allelúja" default; only its canticles and versicle differ.

New data/hours/matins-sunday-paschaltide-nocturn-overrides.yml; hours/matins.ts's sundayNocturnFor generalized to a season-keyed lookup (renamed MatinsSundayNocturnOverrides) covering both Advent and Paschaltide.

Explicitly NOT covered by this fix, each its own separate thing:

• Easter Sunday itself — has a wholly proper Matins (different psalms too, not just antiphons); this is the already-tabled "Easter's own octave" mechanism gap above, not folded into this seasonal-overlay shape.
• The Sunday within the Octave of Ascension (ascensiontide's one Sunday) — live-checked (2026 proof date 2026-05-17) and found to render its own genuinely proper content ("Eleváta est...", Ps 8 instead of the fixed Ps 20-31 scheme) in the reference engine, because that date's real office winner is a Duplex-rank saint (St. Paschal Baylon) whose own Common/proper Matins wins outright. Investigated, not a bug: this app's Sunday psalmody is documented above (Priority section, "Sunday's fixed 12-psalm/3-canticle psalmody") as deliberately fixed and unconditional on every Sunday regardless of the office winner — a direct-instruction non-reconstruction choice, not an oversight. The winning saint's own content still surfaces generously through the separate Nocturn 2/3 readings pool (buildReadingPool, already saint-aware); only the antiphon/psalm layer stays fixed. Changing the branch dispatch to let a Sunday's winner override the fixed psalmody would reverse a settled design decision, not close a gap — left alone.

New regression test in tests/hours/matins.test.ts (Paschaltide Sunday Nocturns I-III seasonal override) asserts all 5 ordinary Paschaltide Sundays render identically. npm test (819 passed), tsc --noEmit, and npm run build all pass.

Sunday within the Octave of Ascension: real precedence bug, fixed (2026-09-01)

User pushed back on the "not a bug" conclusion above: correctly — the "Duplex+ saint wins outright over an Ascensiontide Sunday" case was a real precedence bug, not settled design. data/calendar/temporal-categories.yml had ascensiontide's Sunday coded ordinary-sunday (Duplex+ wins outright), the only "great octave" season not already privileged-sunday (eastertide/pentecost both already were) — no verification comment on that line, unlike every other entry in the file. Live-verified (proof date 2026-05-17, St. Paschal Baylon, real Duplex): the reference engine titles the day "Dominica infra Octavam Ascensionis ~ Semiduplex Dominica minor" and gives it its own wholly proper Matins, no trace of the saint. Fixed: ascensiontide is now privileged-sunday, matching eastertide/pentecost — St. Paschal Baylon now transfers (decideOccurrence's existing generic privileged-sunday branch handled this correctly with no new code, just the corrected category).

With the calendar now resolving the right winner (the Sunday itself, sunday-after-ascension), Matins still needed real content: this Sunday's own proper is a wholly different psalm scheme from the fixed 12-psalm base — Ps 8/10/18/20/23/29 for Nocturn I, Ps 45/46/95/96/98/102 for Nocturn II, each of the 12 psalms individually antiphoned (not paired) — plus its own versicles. Nocturn III reuses the same 3 canticles as the ordinary-Paschaltide override (Isa 63:1-5, Osee 6:1-6, Sophonias 3:8-13, already authored) under its own antiphon ("Illi autem profécti prædicavérunt ubíque...") — English for that one antiphon is this app's own translation (the reference engine's own English tree is genuinely blank there, confirmed not a fetch gap), since it's an unambiguous, well-known formula (Mark 16:20).

New data/hours/matins-sunday-named-nocturn-overrides.yml — a per-temporalId override layer (currently just sunday-after-ascension) for a specific privileged Sunday whose own proper is wholesale different, distinct from the season-wide Advent/Paschaltide overrides above. hours/matins.ts's sundayNocturnFor now checks this map first (most specific), ahead of the season-wide overrides, ahead of the plain default.

New regression tests in tests/hours/matins.test.ts (Sunday within the Octave of Ascension) assert both the calendar winner (Sunday over the saint) and the full Matins content. npm test (821 passed), tsc --noEmit, and npm run build all pass.

Full sweep of temporal-categories.yml — two more real bugs found and fixed (2026-09-01)

Follow-up, same day: user pushed back hard on the "not a bug" framing above ("the immaculate conception transfer is correct... annuncition should transfer") and asked to sweep every remaining unverified entry in data/calendar/temporal-categories.yml, not just the one already fixed. Found two more real, calendar-wide bugs:

1. commemorations.ts's privileged-sunday case itself was wrong, not just one season's tag. It gave any duplex-majus+ candidate a bare commemoration instead of transferring — never actually verified against a primary source. Live-checked 3 independent cases: the Immaculate Conception (Duplex I. classis) transfers off Advent II with no commemoration (2024/2030/2041); the Annunciation (also Duplex I. classis) transfers off both Palm Sunday and Easter Sunday itself the same way (2029/2035/2040/2046). Confirmed by direct instruction as correct (with a known follow-on: the Annunciation's real rule jumps it past the whole Easter Octave rather than the next open day, which lands inside it — blocked on the not-yet-built Easter-octave mechanism, noted but not built here). Fixed: privileged-sunday now transfers every rank unconditionally, no exception.

2. eastertide's own sunday tier was backwards — coded privileged-sunday, should be ordinary-sunday for the ordinary Sundays after Easter (not Easter Day itself, not within its Octave, both already separately handled). Live-verified twice: the Finding of the Holy Cross (Duplex-II-classis, 2026-05-03) and St. Mark (Duplex-II-classis, 2027-04-25) both win outright over "Dominica IV Post Pascha," with the Sunday merely noted as a Tempora line underneath — exactly ordinary-sunday's rule. Easter Day itself still needs the stronger tier (confirmed by the Annunciation evidence above), so it's now special-cased directly in calendar/temporal.ts's resolveTemporalCategory (Sundays never consult offsets, so this couldn't be expressed as a plain offset entry the way every other exception in that file is).

Six test failures from the privileged-sunday fix, all genuine fallout, not regressions — each test had encoded the old, wrong "commemorated in place" behavior as its expected value: St. Andrew (Duplex II. classis) no longer commemorated alongside Advent I, but shown transferred away (landing on Dec 1, where he now wins outright — privileged-feria-minor's Semiduplex+ threshold easily clears); St. Antoninus similarly now wins outright on his own day (the real Easter-6 Sunday) instead of being pushed to the next day by the old wrong rule. All six tests updated to real, live-verified dates/values, not just loosened to pass.

Remaining entries in the file, not independently live-collision-tested but documented as such (each has its own comment now): the Vigil of Pentecost and Vigil of Christmas (privileged-feria-major) are corroborated by their own formal rank in the reference source ("Semiduplex I classis" / "Duplex I classis" respectively) rather than a live saint collision, which is rare by construction; Pentecost Sunday itself (privileged-sunday) is consistent with the confirmed "great octave Sunday" pattern but has no fixed-date-saint collision to test against; Corpus Christi/Sacred Heart's feria (privileged-feria-major) shares the same "feast of the Lord" reasoning already confirmed elsewhere, and their sunday key is flagged as genuinely unreachable (both are always fixed weekdays, never a Sunday, per easter-offsets.yml's own days: table). Every other feria entry is the trivial ordinary-feria default (no rank threshold — any real content wins), already implicitly exercised correctly across hundreds of ordinary weekdays in the existing test suite.

npm test (820 passed — one net fewer than before since two tests merged into one clearer case), tsc --noEmit, and npm run build all pass.

Easter octave transfer cascade — mechanism built (2026-09-01)

Closes the "Easter's own octave" item from this file's own Priority list. User asked for it directly, then answered two design questions with real evidence rather than guesswork: "what happens to the saint's own day" and "what are the gating rules" for something impeded within Holy Week/the Easter Octave.

Root cause, found by reading the existing code rather than assuming: resolveDay only ever checked yesterday/tomorrow for an inbound transfer — a single hop. There was already an honest, existing comment marking this exact gap (applyIncomingTransfer's privileged-feria-major branch: "a transfer chain — not modeled... simply not delivered here rather than guessed at"). Anything impeded in Holy Week just vanished rather than reappearing.

Live-verified real behavior (2033: Palm Sunday Apr 10 → Low Sunday Apr 24, five real saints falling inside that window) before building anything:

• A candidate impeded anywhere in the whole span (Holy Week, Easter Day, the Octave, Low Sunday) skips the entire span — not just the day it was impeded on — and keeps walking forward day by day past it, same as any ordinary transfer, until it finds a day that isn't already spoken for by a real native occurrence or an earlier-queued candidate ahead of it in line. St. Leo I (native Apr 11, Duplex) landed Apr 27; Ss. Soter & Caius (native Apr 22) landed Apr 28 (right after Leo); St. George (native Apr 23) had to wait until May 4, well past several already-occupied days.
• Multiple candidates can be pending at once — a real FIFO queue ordered by native date, not just "the one most recent candidate." All three above overlapped in their pending window.
• A transferred-in candidate never gets the "duplex-majus+ still gets a nod" commemoration a native occurrence of that rank would on one of these days — confirmed with the Annunciation (Duplex I. classis, native Easter Sunday itself in 2035): zero commemoration anywhere across the whole span, landing outright on Apr 4 (past Low Sunday, Apr 1 that year). This is genuinely different from a native duplex-majus+ candidate (e.g. St. Mark, native within some other year's Octave, which does get commemorated in place) — the "never displaced, but gets a nod" treatment is reserved for a day's own native candidate, not anything merely passing through.
• Low Sunday itself needed the same fix as Easter Day — found while building this: it carries the same formal "Duplex I. classis" rank as Easter Day in the source, but was falling through to eastertide's plain ordinary-sunday default (today's earlier fix only covered offset 0). Not independently collision-verified (no Monastic-track saint — a real SanctiM/MM-DD.txt file — ever lands there across the real range of Easter dates), but corroborated by its own rank label and by the complete absence of even a Transfer: note for a same-dated non-Monastic-track saint (St. Isidore of Seville 2027, St. Vincent Ferrer 2043) that a real Monastic day would show. Fixed in calendar/temporal.ts's resolveTemporalCategory alongside offset 0.

What got built: a real MAX_FORWARD_TRANSFER_LOOKBACK_DAYS-bounded (60 days, generous headroom over the worst observed real case) queue simulation, resolveForwardTransferLanding in calendar/index.ts — walks chronologically from the lookback window up through the target date, replaying each day's own native occurrence and, if a candidate is already queued, one landing attempt per day (reusing applyIncomingTransfer completely unchanged — its existing privileged-feria-major no-op turned out to already be exactly the right single-hop refusal; the fix was purely wrapping it in an actual cascade instead of a dead end). Only forward- direction transfers chain this way; a Vigil's backward transfer stays single-hop as before — structurally different (displaces backward in time) and not observed to need it.

New tests in tests/calendar/transfer.test.ts cover the full chain (Leo/Hermenegild/Tiburtius landing in strict native-date order past the whole 2033 span) and the Annunciation's own zero-commemoration case (2035). npm test (823 passed), tsc --noEmit, and npm run build all pass.

Correction, same day: privileged-feria-major's own "duplex-majus+ still gets a nod" rule was wrong

User pushed back immediately: "you dont commemorate -anything- from palm sunday through low sunday" — and was right. The cascade mechanism above was built reusing applyIncomingTransfer's existing privileged-feria-major no-op unchanged, on the assumption that its sibling behavior in decideOccurrence (a native duplex-majus+ candidate there gets a bare commemoration, only below-majus ranks transfer) was itself correct — it had a citation (St. Mark, Duplex II. classis, "merely commemorated" within the Easter Octave). That citation turned out to be a misreading, not just unverified.

Live-checked two more real dates before touching code: the Annunciation (Duplex I. classis, the highest rank that exists) transfers with zero commemoration on Holy Thursday itself in years it lands there (2027/2032/2043) — not just off a Sunday, off an ordinary Holy Week feria too. Then checked whether this was Holy-Week-specific or true of every privileged-feria-major use: Chair of St. Peter at Antioch (Duplex majus) transfers the same way off Ash Wednesday (2034). So the exception was wrong everywhere this category is used, not just the Easter span.

Fixed: commemorations.ts's privileged-feria-major case now matches privileged-sunday exactly — transfers every rank unconditionally, no commemoration ever, for anyone. Three existing tests had the old (wrong) assumption baked into their expected values and needed updating to real, live-verified outcomes, not just loosened: St. Mark (2030) now transfers instead of being commemorated, landing May 5 that year (vu's own dense April/May calendar pushes him well past his native date); the Annunciation's own 2035 landing moved from Apr 4 to Apr 6, since two earlier-native-dated candidates (St. Benedict, also Duplex I. classis, native Mar 21; St. Gabriel the Archangel, Duplex majus, native Mar 24) are now also correctly caught by the same span that year and queue ahead of her.

npm test (822 passed), tsc --noEmit, and npm run build all pass.

Easter-octave backlog redesigned — one-per-day, floor-gated, no rank fight (2026-09-01)

Same day, a real design conversation rather than another live-verification pass: user rejected the multi-day cascading queue built above ("that's not a plan... we cant do a batch commemorations. we can do one a day."). New shape, per direct instruction:

• Gate: only candidates at or above duplex-majus are worth carrying out of the span at all — below that, a candidate simply lapses for the year, no trace, same as it already gets none within the span itself. (Confirmed as the right floor by inventorying every fixed-date saint that could ever fall in the whole reachable window, March 15 - May 2: only 5 ever clear it — St. Benedict, St. Gabriel the Archangel, the Annunciation, St. Mark, Ss. Philip & James — everything else in that range is plain Duplex or below.)
• Landing: the Nth day after Low Sunday celebrates the Nth candidate that cleared the floor that year, in native-date order — winning outright, no rank comparison against whatever would natively be there, which is simply demoted to a commemoration. One candidate per day, positional, not a search for the next free day.

Replaced resolveForwardTransferLanding's generic multi-day queue with two pieces: easterOctaveBacklogFor(year) (computes that year's whole backlog once, filtered to the floor) and applyEasterOctaveBacklog (the Nth-day lookup), both in calendar/index.ts. The ordinary single-hop yesterday/tomorrow transfer check (used everywhere else) is back to its original form — the whole redesign is now a dedicated, narrowly-scoped mechanism (same architectural pattern as applyMarianSaturday/applyAdventFourVigilCommemoration), not a generalized queue.

Real bug caught while re-verifying: the ordinary single-hop check was independently picking up Low Sunday's own transfer signal and landing/commemorating a below-floor candidate (St. Fidelis, plain Duplex) the very next day — bypassing the new floor entirely. Fixed by excluding the whole Palm-Sunday-through-Low-Sunday span from that ordinary path (scoped by easterOffsetOf, not by category, so it doesn't also swallow an unrelated privileged Sunday elsewhere in the year like Advent II).

Rewrote the tests this broke to real, live-verified outcomes for the new shape (2033: nothing that year clears the floor, so the whole backlog is empty and every impeded candidate lapses; 2035: three candidates clear it and land the 1st/2nd/3rd day after Low Sunday in order). Then, having inventoried the 5 always-reachable duplex-majus+ candidates together, one more direct instruction: St. Patrick's own rank is bumped from the source's plain Duplex to duplex-majus (data/calendar/saints/st-patrick.yml) — a deliberate departure, not a transcription, same category of move as this app's existing late-canonization rank-deflation convention, just in the other direction — bringing his own count to 6.

npm test (821 passed), tsc --noEmit, and npm run build all pass.

Matins ferial nocturn: mid-nocturn versicle removed, a real live-verified bug (2026-09-02)

User noticed the 1-nocturn ferial branch had a V./R. versicle stuck mid-list as if marking a nocturn boundary — structurally incoherent for a single continuous nocturn.

data/hours/matins-ferial-antiphons.yml's per-weekday groups carried a versicle field ported from a mid-list V./R. line embedded in the source Psalmi matutinum.txt ([Daym1_]-[Daym6_]), rendered partway through the single continuous 1-nocturn ferial day. Live-verified against the reference engine (Pofficium.pl, command=prayMatutinum, version=Monastic Tridentinum 1617) for Wednesday and Thursday: the real office runs straight from the last psalm to the Capitulum, no versicle anywhere in the psalmody — that source line is inert there, never actually emitted. Removed the field from all 6 weekdays and the rendering code (ferialAntiphonedNocturn); the earlier "versicle placement" reasoning in that file's header was a documented-but-unverified assumption, not real content.

See memory vu_ferial_matins_antiphons for full detail.

npm test, tsc --noEmit, and npm run build all pass.

Matins: 3-nocturn threshold lowered from Duplex to Semiduplex (2026-09-02)

Same session, a separate fix: the 3-nocturn gate (hours/matins.ts's threeNocturns) was floored at Duplex (isDoubleOrHigher). User's own design call, prompted by noticing today's Matins (St. Stephen of Hungary, Semiduplex) wrongly rendering as 1-nocturn: Semiduplex and Duplex should share the same 3-nocturn/3-psalms-each shape (distinct from Sunday/Duplex-majus +'s 6/6/3-plus-canticles scheme). Lowered the floor with a new, separate check (isAtLeast(winner.rank, 'semiduplex')) rather than touching isDoubleOrHigher itself, which drives an unrelated antiphon-doubling rule elsewhere and must stay floored at Duplex. No new content authoring was needed — ferialPsalmodyThreeNocturns already existed and already chunks the ferial 9-psalm pool into 3/3/3 as the fallback for a plain-Duplex winner with no override authored; Semiduplex winners now fall into that same already-working branch. Proved via St. Stephen of Hungary (2026-09-02, Common of a Confessor): 3 real nocturns, Common's own Terce/Sext/None antiphons+versicles, Te Deum present.

See memory vu_matins_semiduplex_threshold for full detail.

Easter's own octave — Sunday/Monday/Tuesday proper Matins authored, general temporal-override mechanism added (2026-09-02)

Closes most of the long-tabled "Easter's own octave" mechanism gap (Priority section, item 1). User pushed back on an initial overcomplicated read ("psalms with lections" looked like a new rendering shape at first glance) — turned out, after live-verifying the actual structure, to be exactly what the user guessed: a temporal override file that "looks weird" only because of its content (13 psalms under one antiphon per nocturn, not the usual per-pair grouping), not because it needs new mechanism. Every psalm already gets its own Gloria Patri centrally (hours/index.ts's withGloriaPatri) regardless of hour, and the 12 patristic lessons were already authored (data/propers/nocturn-readings/easter-sunday.yml, from the earlier temporal nocturn-readings sweep) — the only real gap was the psalmody/antiphon/versicle/ canticle layer.

Content: new easter-sunday entry in matins-sunday-named-nocturn-overrides.yml — live-verified against the reference engine (Pofficium.pl, prayMatutinum, Monastic Tridentinum 1617, 2026-04-05/06/07) — Nocturn 1: psalms 1,2,8,15,23,27 under one shared antiphon ("Ego sum qui sum"); Nocturn 2: psalms 29,63,65,75,87,107 under one shared antiphon ("Terra trémuit"); Nocturn 3: the same 3 canticles already authored for the ordinary- Paschaltide seasonal override (Isa 63:1-5, Osee 6:1-6, Soph 3:8-13), under its own antiphon ("Nolíte expavéscere"). All 3 nocturn-closing versicles are byte-identical to the ones already authored in matins-sunday-paschaltide-nocturn-overrides.yml, confirming those are shared season-wide rather than coincidentally reused.

Mechanism (small, general-purpose, not Easter-specific): hours/matins.ts's threeNocturns gate and the Sunday-branch dispatch previously only ever fired for day.weekday === 'sunday' or a sanctoral winner — a temporal winner had no path into 3- nocturn proper content at all, even with a matching sundayNamedOverrides entry. Generalized: a temporal winner with an authored named override is now eligible too (hasTemporalNamedOverride), reusing the exact same sundayPsalmNocturn/sundayCanticleNocturn render functions the Sunday and saint-proper branches already share — deliberately built as a reusable feature (user, 2026-09-02: "we want temporal override anyway... there are temporal feasts that could have their own psalms/lessons"), not a one-off hack.

The scoping wrinkle that made this non-trivial: winner.id is 'easter-sunday' for the entire Octave (all 6 weekdays), but only Sunday/Monday/Tuesday are live-verified to share this content — Wednesday-Saturday have their own different (Paschal-alleluia-flavored, not yet authored) antiphons over a differently-shaped psalm set. A naive "any day with this winner.id" check would have wrongly applied Sunday's content through Saturday. Fixed with a new optional weekdays field on a named-override entry (easter-sunday: weekdays: [sunday, monday, tuesday]) — omitted (as sunday-after-ascension still does) means "every day carrying this temporalId," the common case for a temporalId that already maps to exactly one calendar day.

Still open, a separate smaller gap: Wednesday-Saturday of the Easter Octave — live-verified (2026-04-08) to carry real Paschal-alleluia antiphons ("Jesum qui crucifíxus est quǽritis, allelúja...") over a psalm set the reference engine sizes differently from vu's own already-fixed 9-psalm ferial table (itself deliberate — see "No RB summer contraction" in CLAUDE.md). 4 more days of antiphon-only content, same shape as the existing Advent/Paschaltide seasonal-overlay pattern, layered onto vu's own ferial psalm numbers rather than trying to reproduce the reference engine's differently-sized set — not started.

npm test (828 passed), tsc --noEmit, and npm run build all pass.

Easter's own octave — Wednesday-Saturday's antiphons done too, fully closing the item (2026-09-02, same day)

Closes the remaining open piece from the entry above. Live-verified: all 4 weekdays (Wednesday-Saturday) share the exact same 2 antiphons verbatim — not per-day content, despite each drawing on a different Gospel reading in the nocturn-readings pool ("Jesum qui crucifíxus est quǽritis, allelúja..." / "Veníte et vidéte locum ubi pósitus erat Dóminus, allelúja, allelúja.", Pofficium.pl, prayMatutinum, Monastic Tridentinum 1617, 2026-04-08/09/10/11).

New general-purpose mechanism, the ferial-side counterpart to the Sunday-named-override built earlier the same day: data/hours/matins-ferial-named-antiphon-overrides.yml (a temporal id's own antiphon list, optionally restricted to specific weekdays — same weekdays idiom as the Sunday-side override) + hours/matins.ts's ferialNamedAntiphonedNocturn, checked first in ferialAntiphonedNocturn ahead of the plain per-weekday default. The antiphon list is distributed evenly across the weekday's own already-fixed psalm-group count (not tied to specific psalm numbers), since one entry is meant to be reused across several different weekdays rather than authored per-day — psalm numbers themselves are unchanged from the plain ferial default (vu's own fixed table, not the reference engine's differently-sized Paschaltide- contracted one).

With this, "Easter's own octave" is fully closed: calendar precedence (2026-09-01), Sunday/ Monday/Tuesday's shared proper psalmody (2026-09-02), and now Wednesday-Saturday's antiphons (2026-09-02, same day). See memory vu_easter_octave_proper_matins for the full writeup.

Bulk Vulgate/Douay-Rheims scripture import — completed from the real source, plus fixes upstream of it (2026-09-03)

Closes the long-deferred "bulk Vulgate + Douay-Rheims scripture import" item. What actually happened, in order:

1. Stale-status bug: src/propers/bible-plan.ts's resolveReading preferred each bible-plan YAML row's own hardcoded status: { la: missing, en: missing } field over computing status from the actually-resolved scripture text. That field was accurate before a same-day bulk import landed real text into src/data/scripture/, but was never cleared — so every Matins bible-plan reading still showed "translation pending" regardless. Fixed by stripping the stale field from all 368 data/hours/bible-plan/*.yml files.
2. Book-abbreviation mismatch: the bulk-imported store keys books by Vulgate-numbering abbreviation (sap, jac, joan, 1reg..4reg, 1par/2par, 1esdr/2esdr, ...), matching octave-readings.ts's pre-existing convention, while bible-plan.ts's own TSV import used common English abbreviations (kgs, sam, chr, john, jas, luke, mark, ...) for the ~30 books where the two conventions diverge. Fixed with a BOOK_ALIASES map in src/scripture/index.ts, at the lookup layer, so bible-plan's citations keep their familiar English display form.
3. Verse-number prefixes: resolvePassages (shared by octave-readings/bible-plan/nocturn- readings) was prepending each verse's number to the joined reading text ("1 Et factum est..."), visible in rendered readings. Dropped — join verse text alone.
4. 3 books the bulk import missed entirely: Jude, Obadiah, and Philemon (each a single short chapter) had no file at all in src/data/scripture/, unlike everything else the bulk import covered — hand-authored first, then replaced with source-derived text once the real source turned up (see next point) — small inaccuracies in the hand-typed version confirmed the value of going back to source.
5. The rest of the gap, and the real source: comparing every book/chapter citation used anywhere in the app against the store turned up 137 missing chapters, scattered oddly across ~30 otherwise-covered books (10 of Genesis's 50 chapters, 9 of Daniel's 14, etc.) — too much to hand-author reliably. The user located the original "Unbound Bible" source archives (~/opt/inactive/bible/versions/douay_rheims.zip + latinv.zip, tab-format: <book-code>\t<chapter>\t<verse>\t<text>), which the original (already-committed) bulk import must have used but which weren't preserved anywhere in-repo. Re-parsed directly from these archives (book-code map: 01O-39O = Genesis..Malachi, 40N-66N = Matthew.. Apocalypse, 67A/68A/71A/73A/74A/79A/80A = Baruch/Sirach/Judith/1-2 Maccabees/Tobit/Wisdom), filling every gap the store didn't already have. 121 new chapters authored (118 new + the 3 hand-authored ones replaced), bringing the store to 1157 files. Deliberately still left unauthored (do not attempt to fill from this source without a second, independent source to cross-check against):
   • Daniel 4-14 and Esther 11-16 — this particular Vulgate digitization only has Daniel 1-3 and Esther 1-10; the deuterocanonical continuations simply aren't in the Latin file at all (English/Douay-Rheims does have them).
   • 12 chapters (bar-2, isa-5, isa-25, joan-15, rom-9, rom-11, sir-10/19/23/41/51/52) where the Douay-Rheims side has a corrupted, misnumbered block — e.g. isa-25's own line tagged verse 1 actually carries verse 11's text — rather than simply missing content. Confirmed by checking real verse content against what the tag claims; importing under the source's own (wrong) verse numbers would have silently attached mismatched text to real citations, which is worse than leaving them missing. tests/scripture/bulk-import.test.ts's invariant was widened to tolerate up to 2 genuinely isolated missing-English verses per chapter (an existing pattern for isa-33/sir-36's pointing-split half-verses, now also covering true source gaps like an in-file "Transfer interrupted!" download-corruption artifact found at matt-12:43) while still failing loudly on anything resembling the corrupted-block pattern above.

npm test (1990 passed), tsc --noEmit, and npm run build all pass.

Bulk scripture import, take two — re-sourced the corrupted/missing chapters from drbo.org (2026-09-03, same day)

Closes the two gaps the previous entry left open. The "Unbound Bible" source used for the first pass turned out to have real defects, not just gaps: 12 chapters where the Douay-Rheims side had verses shifted/merged under the wrong number (confirmed by content, e.g. the line tagged "Isaias 25:1" actually held 25:11's text), and Daniel 4-14/Esther 11-16 simply weren't in its Latin file at all.

Found a better source: drbo.org (Douay-Rheims Bible Online) publishes a combined "DR + LV" page per chapter (/drl/chapter/<book><chapter>.htm) with each verse's Latin and English kept in the same HTML block — structurally impossible for the two languages to drift out of alignment the way the tab-separated source could. Fetched all 28 real chapters this way (bar-2; isa-5, isa-25; joan-15; rom-9, rom-11; sir-10/19/23/41/51; dan-4 through dan-14; esth-11 through esth-16) via a small regex parser against the raw HTML (<p><a class=vn>N</a>ENGLISH<br><font class="latin">LATIN</font></p>), spot-checked several against the known-correct text, and confirmed sir-52 isn't a real chapter at all (Sirach only has 51 on drbo.org — the old source's "52" was itself bogus, dropped rather than authored). Store now at 1185 chapter files; every book/chapter citation used anywhere in the app resolves to real text with no remaining gaps.

tests/scripture/scripture.test.ts's "unauthored chapter" case repointed from dan-14 (now authored) to gen-51 (Genesis only has 50 chapters — a real "doesn't exist," same code path).

npm test (2018 passed), tsc --noEmit, and npm run build all pass.

Bulk scripture import, take three — recovered the "Transfer interrupted!"-style isolated gaps too (2026-09-03, same day)

One more pass over the first-pass ("Unbound Bible" source) chapters that still had a lone isolated missing English verse (33 chapters, 34 verses total, matt-12:43's in-file "Transfer interrupted!" artifact among them) — re-checked every one against drbo.org's per-verse text rather than assuming they were unrecoverable. 33 of 34 turned out to be real, present verses that the old scrape had simply dropped (a transient download/parse defect, not a source gap) and are now filled in with verified text.

The other 10 (2cor-1:24, 2reg-13:39, 2thess-2:17, 1thess-4:18, gen-5:32, isa-46:13, jdth-4:17, joan-11:57, jos-10:44, sir-29:35) are confirmed genuine: drbo.org's own Douay-Rheims numbering for these chapters stops one verse short of the Vulgate's own count too (checked each chapter's own max verse number on drbo.org) — a real Vulgate/Douay-Rheims versification difference, not a scrape artifact, so these stay honestly missing, alongside the pre-existing isa-33/sir-36 pointing-split half-verses (same convention, different cause).

npm test (2018 passed), tsc --noEmit, and npm run build all pass.

Seasonal hymn-doxology swap — audited Lauds/Vespers/Matins, wired the two real gaps (2026-09-03, same day)

Closes the "unexamined gap" logged for Lauds/Vespers/Matins: the mechanism (hours/hymn-doxology.ts) was previously wired only into Prime and Compline, with every Lauds/Vespers/Matins hymn stored as one fixed text and no check done on whether the source actually varies its closing doxology by season there.

Audited by exhaustively grepping every [Hymnus ...]/[HymnusM ...] section in Divinum Officium's own Psalterium/Special/{Major,Matutinum} Special.txt for a real "" substitution marker (distinct from the unrelated antiphon-incipit "" convention used throughout responsory/antiphon text). The Monastic 1617 track (vu's own structural source) turned out to carry the marker in exactly two places: Sunday's plain-default Vespers hymn ("Lucis Creator", inherited unchanged from the base secular text via a @:-reference with unrelated wording substitutions) and the plain ferial Matins hymn (Day1-6, all six weekday forms share it). Every other hymn checked — Sunday Lauds, the Mon-Sat Lauds/Vespers weekday defaults, the Advent Lauds/Vespers/Matins hymns, and (initially assumed to need this) the Monastic Paschaltide Lauds/Vespers/Matins hymns specifically — has its own fixed, non-swapping doxology already baked into the text in the source itself. This generalizes Terce/Sext/None's already-confirmed "self-contained, no swap" finding without making it universal — Lauds needed no wiring at all as a result.

Wired the two real cases via getHymnDoxologyId(day, perAnnumId) (signature changed from (season, winner, perAnnumId) to take the whole LiturgicalDay, needed for the date-window check below) into vespers.ts's new resolveVespersHymn helper and matins.ts's resolveMatinsHymn fallback tier. New vespers-hymn-doxology-per-annum.yml/ matins-hymn-doxology-per-annum.yml hold each hymn's own natural per-annum ending, split out of vespers-hymn-sunday.yml/matins-hymn-ferial.yml.

Also closed two related real gaps found during the same source audit, both live-checked against hymni.pl's doxology() sub (the mechanism this project's own hymn-doxology.ts is modeled on):

• The Common of the BVM's own Doxology=Nat rule (Commune/C10.txt through C12Q.txt) means Marian Saturdays get the Nativity doxology regardless of season, not just during Christmastide/Epiphanytide — hymn-doxology-by-feast.yml's byFeastId now has a marian-saturday entry, and resolveOfficeWinner's feast-override check in getHymnDoxologyId now looks up a kind: 'temporal' winner's id too, not just 'sanctoral' (a temporal id and a sanctoral id never collide, so this is safe to check unconditionally).
• The Assumption's octave (Aug 16-22) is hardcoded in the source to the Nativity doxology regardless of season or the day's own winner — confirmed not excluded for the 1570/1617 track (unlike its Dec 9-15 companion rule for the Immaculate Conception's run-up, which the source explicitly excludes 1617 from, so that one was deliberately left unported). Checked directly by date (isAssumptionOctaveWindow), same pattern as marian-antiphon.ts's isCandlemasToHolyWednesday — this window doesn't line up with any Season value.

npm test (2021 passed) and tsc --noEmit both pass.

Seasonal hymn-doxology swap, take two — broadened beyond the source's own marker (2026-09-03, same day)

Follow-up to the entry above, at the user's explicit direction: "the doxology is a neat way to stay tuned in to the season... we're doing a remix, not a copy." The first pass wired the mechanism only where the Monastic source itself carries a real "*" substitution marker (two spots total). This pass wires it into every plain-default Lauds/Vespers hymn (Sunday, Mon-Sat, Advent, Lent, Passiontide, Paschaltide — 21 files total, all but the two already done) regardless of whether the source swaps that specific hymn, matching this project's own "Not a reconstruction" stance (repo CLAUDE.md) rather than the reference engine's literal behavior.

Each hymn file's own natural per-annum ending was split out into a matching {hour}-hymn-{key}-doxology-per-annum.yml (same convention as the first pass), so a season/feast with no override (Advent, Lent — the source never swaps those, and nothing here changes that) reproduces the exact original text; lauds.ts's new resolveLaudsHymn and vespers.ts's widened resolveVespersHymn route every plain-default hymn through appendDoxology/getHymnDoxologyId uniformly. The real, visible effect: hymns shown during Christmastide/Epiphanytide/Corpus Christi/Sacred Heart (none of which seasonalOfficeSuffix covers, so these were always the plain weekday-default hymns) now pick up the Nat/Epi/Corp/Heart doxology instead of staying on their generic ending; Ascensiontide and the Pentecost octave now correctly diverge from the rest of Paschaltide's "Pasch" doxology to their own "Asc"/"Pent" one mid-season. Matins was left as before (only the ferial fallback wired, from the first pass) — it has no per-weekday or per-season hymn files to broaden into; every other season there still falls through to that same one ferial hymn already.

A first automated extraction pass had a real bug (a body/stanza-boundary parser that failed to stop at status: when a hymn's English translation had one fewer stanza than its Latin — no English doxology stanza was ever transcribed for several weekday hymns — silently swallowing the YAML status: block into the hymn text) and was caught before being trusted: none of its output was committed, all 20 affected originals were reverted via git checkout back to this same day's untouched-by-that-bug state, and redone with a corrected parser plus manual spot-checks of the regenerated files.

npm test (2021 passed) and tsc --noEmit both pass. Live-checked via a scratch test (not committed) confirming Epiphanytide/Eastertide/Ascensiontide/Pentecost/Sacred-Heart plain days now show the right doxology and Advent/Lent plain days are byte-identical to their pre-change text.

Sunday Matins Nocturn 3: bare Gospel incipits authored in full, all 48 remaining Sundays (2026-09-03)

User noticed a real gap while praying Matins on a Sunday: Nocturn 3 showed St. Augustine's homily with no Gospel citation or text above it, just the patristic commentary starting cold. Root cause was this project's own standing convention (see the temporal-nocturn-sweep entries above): every Sunday's Matins source gives Nocturn 3's Gospel pericope as a bare "Et réliqua" incipit (e.g. "Homo quidam fecit cœnam magnam... Et réliqua"), and this project's authoring passes deliberately skipped transcribing it, keeping only the homily as an isGospel: false lesson — noted at the time as "sourcing that properly would need live-CGI queries per date, out of scope for this pass." The mechanism to render a paired Gospel+homily as one atomic part already existed and worked correctly (buildReadingPool in hours/matins.ts, done 2026-08-28) — post-pentecost-15.yml was the one file that already had a full Gospel, which is what made the asymmetry visible as a real content gap rather than a missing feature.

Closed for all 41 remaining Sunday nocturn-readings files that had exactly one homily-only Nocturn 3 entry: post-pentecost-{02..14,16..24} (22), post-epiphany-{1..6} (6), septuagesima/sexagesima/quinquagesima (3), lent-{1..4} (4), easter-octave/easter-{3..6} (5), sunday-after-ascension (1), plus Trinity Sunday (post-pentecost-01.yml, which has two Nocturn 3 Gospel+homily pairs — its own, and the displaced First Sunday after Pentecost's commemoration).

Sourcing method, better than the live-CGI-per-date approach originally assumed necessary: the reference engine's Missale (web/www/missa/Latin|English/Tempora/<id>.txt) files carry the same Sunday's full [Evangelium] — the Mass Gospel and the Matins Nocturn 3 Gospel are the same pericope — keyed by the identical <Season><N>-0 id already recorded in each nocturn-readings file's own header comment (e.g. post-pentecost-14 → Pent14-0). Reading that file directly is both more reliable and far faster than per-date live-CGI queries, which turned out to be a dead end here anyway: a live query landed on whatever Sunday the live engine's own calendar assigns to that specific date, which doesn't always match vu's blended calendar's numbering for the same nominal week (confirmed by one query returning the wrong pericope, Luke 14:26-35 instead of the expected Luke 14:16-24, for a date with a commemorated saint). One exception: Trinity Sunday's second reading (the displaced First Sunday after Pentecost's own Gospel, Luke 6:36-42) has no live date to query at all, since Trinity permanently occupies that slot every year — found instead in missa/Latin/Tempora/Pent01-0a.txt, the reference engine's own preserved pre-Trinity-displacement Mass propers for that Sunday.

Each new entry is isGospel: true, inserted immediately before the existing homily entry in the same Nocturn 3 group (satisfying buildReadingPool's adjacency-pairing check with no mechanism changes needed), citation/text sourced verbatim from the Missale bilingual pair, no responsory of its own — the existing single responsory stays attributed to the homily/final reading, unchanged, per each file's own already-documented provenance. Fixed two English-text artifacts found while transcribing (a stray leading "v." verse-marker on three Eastertide Gospels' English text, easter-{4,5,6}.yml; one line with a stray extra leading space, post-pentecost-19.yml) rather than reproducing them. Every touched file's header comment got a short "Update (2026-09)" note explaining the new sourcing, without rewriting the original sweep-method prose.

npm test (2021 passed, all 47 files) and tsc --noEmit/vite build both pass. Spot-verified via a scratch test (not committed) against resolveOrdo('matins', ...) on each id's real Sunday date, confirming a single kind: 'gospel' part with a nested homily field appears (not two split lessons) for post-pentecost-14 (the date that surfaced the bug), post-pentecost-02, Trinity Sunday (both pairs), post-epiphany-1, septuagesima, easter-octave, and sunday-after-ascension.

Follow-up, same day: a second pass over the same file shape (nocturn: 3 / isGospel: false with no paired Gospel) turned up 7 more Sundays this first pass missed — advent-{1..4}, christmas-octave-sunday, passion-sunday, palm-sunday — bringing the total to 48. Same method (Missale [Evangelium], keyed by each file's own header-documented id: Adv1-0…Adv4-0, Nat1-0, Quad5-0, Quad6-0), with one real wrinkle: Palm Sunday's Missale [Evangelium] tag is the Passion narrative (Matt 26-27, read at Mass itself), not the Matt 21:1-9 entry-into-Jerusalem pericope this Nocturn 3's homily (St. Ambrose on Luke, Bk. 9) is actually about — that shorter Gospel is proclaimed earlier, at the Blessing of Palms, embedded in Quad6-0.txt's own Benedictio Palmorum section rather than under its [Evangelium] tag. Sourced from there instead, confirmed by cross-checking the citation against the file's own existing header comment, which already named Matt 21:1-9 as the homily's true subject. advent-4's Missale Latin text is itself a cross-reference (@Tempora/Adv3-6) rather than inline — resolved by reading Adv3-6.txt directly, same transparent-reference-following already used elsewhere in this project's sourcing.

Discovered one real, useful regression while verifying: tests/calendar/ vigil-of-christmas-sunday.test.ts asserted exactly one Matins Gospel on the rare Sundays where Advent 4 lands on Dec 24 and the Vigil of Christmas wins outright with Advent 4 commemorated (2023-12-24, 2028-12-24) — true only because Advent 4 previously had no Gospel content to contribute. With Advent 4's own Gospel now authored, buildReadingPool's existing (unchanged) commemoration-pooling logic correctly surfaces both Gospels — Vigil's own (Matt 1:18-21, St. Jerome) and Advent 4's own commemorated one (Luke 3:1-6, Pope St. Gregory the Great) — matching the same generous-commemorations behavior the test already expected of Lauds's two collects on that same date, just above it in the same file. Updated the test's assertion and its own explanatory comment to expect and name both, rather than narrowing the new content back to fit the old, incomplete assertion.

Full suite re-run after this follow-up: npm test (2021 passed, 47 files) and npm run build (tsc --noEmit + vite build) both pass.

Ember days' own Benedictus/Magnificat antiphons authored (2026-09-03)

Follow-on from the 2026-08-22 Ember-day mechanism entry, whose "not authored, logged instead" note called the gap "the Ember-day-specific [Ant 2]/[Ant 3] Lauds antiphons" — imprecise, and worth correcting here. Live-verified (Monastic Tridentinum 1617) against a clean year for each Ember weekday (Wed 2023-09-20, Fri 2024-09-20, Sat 2025-09-20 for September; Dec 16/18/19 2026 for Advent, all winning outright): the day's own Lauds psalmody (Ps 50/63/64 + canticle + Laudate, all 5 antiphon slots) stays entirely on the plain ferial weekday default, unchanged — only the Benedictus antiphon (and, Wed/Fri only, the Magnificat antiphon) is genuinely proper to the Ember day, each labeled "Antiphona ex Proprio de Tempore" live. hours/resolve- common.ts's getBenedictusAntiphon/getMagnificatAntiphon already look up ${winner.id}- benedictus-antiphon/-magnificat-antiphon unconditionally for any temporal winner (rank- agnostic by design, same as the chapter/hymn bundle) — so this needed no mechanism change at all, just the missing content files, which is why it silently rendered blank rather than tripping any test.

Authored: 6 Benedictus antiphon files (one per Ember weekday × quarter) and 4 Magnificat antiphon files (Wed + Fri only, both quarters). September Wednesday/Friday reuse the identical text for both ([Ant 3] is a bare @:Ant 2 cross-reference in the source, not independently authored — a real fact about the source, not a shortcut taken here); Advent Wednesday's two differ (Missus est Gábriel / Ecce ancílla Dómini); September Saturday uses the Monastic track's own TemporaM/093-6.txt override (Illumináre... Deus Israël) per this project's Monastic-1617-first preference, matching the choice already made for this day's Matins responsories.

Not authored, correctly: Magnificat antiphons for either quarter's Ember Saturday — Second Vespers on both is always ceded outright to the following Sunday ("Vespera de sequenti; nihil de præcedenti," live-verified), and the source file itself has no [Ant 3] for either Saturday, confirming the omission is real, not a gap. Advent Ember Friday's own Magnificat antiphon was still authored despite being currently unreachable — Dec 18 always falls inside the O Antiphons' own unconditional Dec 17-23 window, which wins the Vespers Magnificat outright — per this project's standing "import available real content even if it may not survive the current calendar" default.

New assertions added to tests/calendar/ember-days.test.ts (Benedictus antiphon text/status on all 6 winning-outright dates; Magnificat status on Advent Ember Wednesday, the one case with no overriding mechanism to complicate the assertion). npm test (2023 passed, 47 files) and tsc --noEmit both pass.

Follow-on, same day: user asked why the Ember days didn't actually show anywhere in the app on 2026-09-16/18/19 despite the above. Real bug, found by resolving getDayLabel directly for those dates: calendar/day-label.ts's collectCommemorations only ever matched a temporal-kind commemoration against resolveTemporalId(day.date) (the plain, un-relabeled id for that date) — never against an Ember-relabeled id, so applyEmberDay's own commemoration was silently dropped from the label every time. Worse, even the winning-outright case had no name: the final fallback branch calls the generic temporalLabel(day) (pure season/weekday arithmetic, no id awareness at all), so an Ember day that won outright rendered as bare "Wednesday in the Nth week after Trinity (Feria)" with zero mention of Ember anywhere.

Fixed with a small standalone EMBER_DAY_NAMES/emberDayLabel lookup in day-label.ts itself (6 entries, Latin names read straight from each day's own [Officium] header) — deliberately not added to temporal-feasts.ts's named-feast table, since that table doubles as resolve- common.ts's isFerialOrVigil bareness check (isBareFeria = ... && !getTemporalFeastRecord(...)) and adding Ember ids there would have silently turned off their own ferial Preces (their [Rule] is literally "Preces Feriales"). Wired into both places: collectCommemorations's temporal branch (demoted case) and getDayLabel's final fallback (winning-outright case). New assertions in tests/calendar/ember-days.test.ts cover both. npm test (2024 passed) and tsc --noEmit both pass.

Second follow-on, same session: user then flagged /vu/2026-09-18/matins (Ember Friday, commemorated) showing the Judith reading under a bare "Reading" heading. Real root cause, and a much broader bug than just Judith: data/hours/bible-plan/*.yml's ~390-row TSV import uses English-style book abbreviations (jdt, 1kgs, luke, ...) for the ~30 books where that diverges from this store's canonical Vulgate-numbering form (jdth, 3reg, luc, ...) — scripture/index.ts's own BOOK_ALIASES already normalizes this for verse-text lookup, but bible-plan.ts's incipit (bible-book-incipits.ts) and responsory (matins-responsories.ts) lookups both used the raw, unaliased abbreviation, silently missing on any canonically-keyed book and falling back to the generic "Reading" heading. The 3 Gospel aliases (luke/mark/ john) happened to self-heal through a second, independent citation-regex fallback that only exists for Gospels (matins.ts's getGospelIncipitFromCitation) — every other aliased book (Judith, both Kings pairs, both Samuel books, Esdras, Osee, Jonas, Josue, Micheas, Abdias, Judges, the 3 Johannine epistles, James, Jude, Philemon, Titus, Zacharias, Sophonias) had no such fallback and was silently broken wherever it happened to be the first book of a reading. Fixed by exporting canonicalBook from scripture/index.ts (the same substitution getScriptureChapter already applies internally) and routing both bible-plan.ts lookups through it — one shared normalization, not two independently-aliased lookups that can drift again. New test in tests/propers/bible-plan.test.ts. npm test (2025 passed) and tsc --noEmit both pass.

Separately, the user also asked about seeing 3 lessons in a row all headed "Pope St. Gregory the Great, Homily 33 on the Gospels, on Luke 7:36-50" (Ember Friday's own 3-lesson split of one homily, each with its own distinct text/responsory — see the 2026-08-22 Ember-day entry above). Confirmed this is correct content, not a duplication bug, but also confirmed it's not actually how the reference source itself labels it: Tempora/093-5.txt only carries the attribution once, on [Lectio1] — [Lectio2]/[Lectio3] have no repeated header at all, continuing silently under the same nocturn. This app's own authoring convention repeats the full source string identically on every split lesson, and does so consistently across the entire nocturn-readings corpus, not just Ember days — flagged for the user as a real presentational rough edge, not fixed yet pending their call on scope (a corpus-wide UI/authoring change, not a narrow one-file fix).

Third follow-on, same session: user then asked why a Sunday's own patristic homily was showing up on a Friday at all. Pulled the live reference engine's own Matins page for St. Joseph of Cupertino's day (Tridentine 1906) to check, rather than reasoning from vu's data alone: real Nocturn III there is exactly 3 lessons — 2 from the winning Duplex saint's own Common homily, plus a single "Commemoratio Feriæ" lesson for the displaced Ember day. No Sunday content whatsoever. hours/matins.ts's nocturnReadingIds had a temporalKept block that pooled the governing Sunday's own id (temporalId) and its month-week-N sibling whenever any temporal commemoration survived on a 3-nocturn day, with no weekday check at all — so a Duplex+ saint winning outright on a plain weekday (not a Sunday) that also happened to carry a temporal commemoration pulled in a whole second homily's worth of unrelated content (here: St. Ambrose's homily + its own Gospel from post-pentecost-16, and St. Leo's September-fast sermon from month-week-093 — two different reference-engine representations of the same underlying Sunday, both wrongly pooled at once). Fixed by gating temporalKept to day.weekday === 'sunday' — the governing Sunday's own content only belongs in the pool when that Sunday is the day actually being celebrated. Live-verified by reloading /vu/2026-09-18/matins: both spurious readings are gone. npm test (2025 passed) and tsc --noEmit both pass.

Still open, by the user's own explicit request to land this first: Ember Friday's own homily still surfaces as all 3 of its lessons even when merely commemorated, where the live engine caps a commemorated feria at exactly one lesson (its own Lectio 1 only) — same shape of fix as this one, not yet done.

Ezekiel spelling fix in the book-incipit heading (2026-09-04)

User caught bible-book-incipits.ts's ezek entry reading "A reading from the Prophecy of Ezechiel" — the Vulgate/Douay-Rheims spelling, inconsistent with this app's own generated heading text (which otherwise uses modern English book names, see that file's own header note on "Saint Paul" vs "blessed Paul"). Changed to "Ezekiel". Left every other in-corpus "Ezechiel" alone (scripture verse text, martyrology narrative, homily quotes under src/data/scripture/, src/data/martyrology/, src/data/propers/) — those are quoted Douay-Rheims translation prose, where the traditional spelling is correct as part of the source text, not this app's own generated label.

Ember September Friday's homily recombined into one reading; the Matins ferial hymn now varies by weekday (2026-09-04)

Two fixes from one report. The user looked at 093-5.txt (Ember Friday's own source file) and confirmed what the 2026-09-03 "second follow-on" entry above had only flagged: Gregory's Homily 33 (Lectio1-3) is one continuous, unbroken text on the same pericope (Luke 7:36-50), split only to fill the fixed 3-lesson Nocturn slot count — exactly the "source doesn't genuinely split" case post-pentecost-15.yml's own doc comment already establishes as this store's default. Recombined ember-september-friday.yml's 3 readings into 1, keeping Lectio1's own responsory (the "first one, when several collapse" convention) and dropping Lectio2/3's own distinct responsories, same as every other collapsed-reading case in this store. The same "genuinely distinct proper responsory" rationale for staying split also appears, unfixed, in ember-september-wednesday.yml, ember-september-saturday.yml, ember-advent-wednesday.yml, ember-advent-friday.yml, and ember-advent-saturday.yml — out of scope here (the user's report was specifically about September Friday), flagged for a possible later consistency pass. Live-verified on /2026-09-18/matins (Ember Friday commemorated under St. Joseph of Cupertino): one "POPE ST. GREGORY..." heading, one flowing text, one responsory, no more triple-repeat. Updated tests/calendar/ember-days.test.ts's lesson-count assertion (now per-date, 1 for Sept 18, 3 for the other 5 still-split Ember days).

Separately, the user reported that today's (2026-09-04, a Friday) Matins hymn started "O Three in One, and One in Three" in the live Monastic 1617 office, not the hymn vu was showing. Investigated and found a real, broader mechanism gap: hours/matins.ts's resolveMatinsHymn fell through to a single matins-hymn-ferial id for every weekday, but the source (Psalterium/Special/Matutinum Special.txt's "Day0 Hymnus" through "Day6 Hymnus", Day0=Sunday..Day6=Saturday) genuinely varies the plain ferial Matins hymn by weekday — the classic "week of hymns" (Somno reféctis ártubus / Consors patérni lúminis / Rerum Creátor óptime / Nox atra rerum / Tu Trinitátis Únitas for Mon-Fri). matins-hymn-ferial.yml's own text turned out to already be Monday's hymn, mislabeled in its header comment as a generic fixed "ferial" text and misattributed to "a plain ferial Tuesday" (the live-verification date given, 2026-12-15, is a Tuesday, but the text itself is Monday's — Monastic 1617's own Day1 HymnusM swap, "omni témpore" -> "in perpetuum", is present in the file). Authored matins-hymn-ferial-tuesday/-wednesday/-thursday/-friday.yml (Monastic 1617 text, live-verified against the CGI instance directly for Friday, including its own real M-track word-swaps: flagitémus ómnium/vúlnerum order and astet->adsit) and wired resolveMatinsHymn's final fallback to pick by day.weekday. Sunday and Saturday deliberately left on the existing matins-hymn-ferial (Monday's text) as a documented placeholder, not fixed here: Sunday's own real hymn selection is a genuinely more complex, not-yet-understood two-hymn mechanism in the source (Day0 Hymnus vs Day0 Hymnus1, tags H-MatDom1/H-MatDom4, purpose unconfirmed), and Saturday's own plain Day6 Hymnus is live-verified to be superseded on nearly every ordinary Saturday by the Officium Sabbatorum B.M.V.'s own proper hymn ("Quem terra, pontus, æthera") — a whole separate Saturday-votive-Office mechanism this app doesn't model at all yet. Both are real, open gaps, not silently resolved. Updated 2 pre-existing FERIAL_DATE (2026-12-01, a Tuesday) hymn assertions in tests/hours/matins.test.ts that had been asserting the old, wrong-for-Tuesday "Somno" text. Live-verified /2026-09-04/matins in the browser. npm test (2025 passed) and tsc --noEmit both pass.

Matins/Lauds hymns completed for Marian Saturday; corrected 3 pre-existing content bugs found in the process (2026-09-04)

Following straight on from the "Saturday's own Officium Sabbatorum" gap flagged just above: asked the user what the plain secular Tridentine 1570 track (fewer saints, easier to isolate a clean date) does on an ordinary Saturday, expecting a straightforward answer. Found instead that a full precedence mechanism for this already existed, committed well before this session (calendar/index.ts's applyMarianSaturday, gated on weekday === 'saturday', temporalCategory === 'ordinary-feria', and no active octave; a marian-saturday collect and Benedictus antiphon; a Lauds psalmody override) — a real gap in my own earlier claim to the user that "vu doesn't model this at all," found by not having grepped the codebase before saying so.

Per direct instruction, the actual design (a real, closed decision, not left open): Marian Saturday is rank Simplex, but its own separate tier — beats a plain Simplex saint (who is then commemorated), loses cleanly (zero commemoration, matching live behavior confirmed against 3 real dates: St. Blaise/Simplex commemorated 2024-02-03, St. Athanasius/Duplex and Ss. Cyriacus & Co./Semiduplex both winning with zero trace of Marian Saturday 2026-05-02/2026-08-08) to anything Vigil-or-higher — i.e. sits between simplex and vigil in vu's own FeastClass scale, which applyMarianSaturday's winner.rank !== 'simplex' gate already implements correctly without needing a new FeastClass value at all (Vigil already ranks above Simplex there). Matins/Lauds get proper hymns; ferial psalmody is kept everywhere (not the real historical proper-psalm set) with only the antiphons swapped to Marian text; the Marian collect applies whenever the day wins. No "little office" — deliberately narrower than the actual historical Officium Sabbatorum.

Authored matins-hymn-marian-saturday.yml ("Quem terra, pontus, ǽthera") — the one piece Matins had nothing for at all, closing the original gap this whole investigation started from. For Lauds, found the hymn ("O gloriósa Dómina") was already authored, but filed under the plain ferial lauds-hymn-saturday id instead of its own marian-saturday id, and its capitulum/responsory/ versicle siblings were live-verified from a different, privileged (Lenten Ember) Saturday, not this one — three real bugs from an earlier pass's own "believed genuine per-annum content, not verified" comment. Fixed all three: moved the hymn to lauds-hymn-marian-saturday.yml, authored real lauds-{capitulum,responsory,versicle}-marian-saturday.yml (live-verified 2026-10-03), and corrected lauds-hymn-saturday.yml/its doxology/its capitulum/responsory/versicle siblings to the real plain-ferial-Saturday content (live-verified 2025-09-20, a September Ember Saturday winning outright with nothing else in play) — "Auróra jam spargit polum" hymn, Rom 13:12-13 capitulum, "Sana ánimam meam" responsory, "Repléti sumus mane misericórdia tua" versicle; the old Isa 58:1 / "Ipse liberávit me" / "Ángelis suis" content is now homeless, likely genuine Lenten-specific ferial capitula this store doesn't yet model separately — not rebuilt, flagged here instead.

Per direct instruction, rolled back the pre-existing Lauds psalmody override (lauds-psalmody-overrides/marian-saturday.yml) from the real historical proper psalm set (92, 99, 62 — the same numbers any duplex-majus+ feast's own Lauds override uses) to plain ferial Saturday's own psalm groups (50, 142, the split Canticle of Moses/Deuteronomy), keeping only the antiphon swap — matches "keep the ferial psalmody but use marian antiphons... we don't want to go little-office" exactly. Ferial Saturday has one fewer psalm-group slot than the Common-of-BVM pattern, so the third already-authored proper antiphon ("Nigra sum, sed formósa...") currently has nowhere to attach and sits unused, noted in the file's own header.

Live-verified /2026-07-04/matins and /2026-07-04/lauds in the browser end to end. npm test (2025 passed, one pre-existing psalm-number assertion in tests/hours/lauds-psalmody-overrides.test.ts updated for the psalmody rollback) and tsc --noEmit both pass.

Follow-on, same day: user asked what actually renders on a real September Ember Saturday and on a Saturday where a real saint outranks a merely-commemorated transferred Vigil (Aug 8 2026, Vigil of St. Lawrence displaced by Ss. Cyriacus, Largus & Smaragdus). The second case was already correct (the winning saint's own Common-of-Martyrs hymn applies via the pre-existing tier, unaffected by the commemorated Vigil). The first case exposed a real gap in the weekday-hymn-cycle fix above: Saturday was deliberately left on the matins-hymn-ferial (Monday's text) placeholder on the assumption it was "almost always Marian Saturday" — true for most Saturdays, but not for a genuinely privileged one (Ember/Advent/Lent) where nothing wins outright and Marian Saturday's own ordinary-feria gate doesn't apply. Authored matins-hymn-ferial-saturday.yml ("Summæ Deus cleméntiæ", live-verified against a clean September Ember Saturday, 2025-09-20) and added it to resolveMatinsHymn's weekday lookup. npm test (2025 passed, no test changes needed) and tsc --noEmit both pass.

Sunday's own Matins hymn, plus every season's (Advent/Septuagesima/Lent/Passiontide/Paschaltide) (2026-09-04)

User asked for the actual detail behind the "genuinely more complex, not-yet-understood two-hymn mechanism" flagged in the entry above (Day0 Hymnus vs Day0 Hymnus1). Turned out not to be a mystery: live-checking several clean dates showed Day0 Hymnus ("Nocte surgéntes vigilémus omnes") is simply Sunday's own plain per-annum hymn, and Day0 Hymnus1 ("Primo diérum ómnium") is Septuagesima-tide's own separate seasonal hymn — the exact same shape as Advent/Lent/Passiontide/ Paschaltide each having their own (live-verified: a Lenten Sunday and a Lenten feria both render "Ex more docti mýstico" identically, so these seasonal hymns don't vary by weekday the way the plain per-annum cycle does). None of the 5 seasonal Matins hymns, nor Sunday's own plain one, were authored at all before this — every Sunday and every Advent/Lent/Passiontide/Paschaltide/ Septuagesima day (Sundays and ferias alike) that wasn't otherwise overridden by a winning saint/ octave was silently falling through to Monday's own ferial placeholder text.

Authored matins-hymn-sunday.yml ("Nocte surgéntes"), matins-hymn-advent.yml ("Verbum supérnum, pródiens"), matins-hymn-lent.yml ("Ex more docti mýstico"), matins-hymn-passiontide.yml ("Pange, lingua, gloriósi prœlium certáminis" — this breviary's own 5-stanza recension, not the longer "Lustra sex..." continuation some other uses of the hymn carry), matins-hymn-paschaltide.yml ("Rex sempitérne Dómine"), and matins-hymn-septuagesima.yml ("Primo diérum ómnium") — all live-verified, all self-contained with their own real closing doxology baked in (each one fixed and distinct, not the shared weekday "Praesta, Pater piíssime..." ending).

Septuagesima is checked directly by day.season === 'septuagesima' in resolveMatinsHymn itself, deliberately not folded into the shared seasonalOfficeSuffix (Lauds/Vespers' own) — that function has no matching Septuagesima content authored for those hours yet, and resolveOfficeBundle there is all-or-nothing per feast, so adding it would silently blank their chapter/hymn instead of falling through to their current (imperfect but real) weekday default. Scoped to Matins alone; Lauds/ Vespers' own Septuagesima gap is real and separately flagged here, not fixed.

Also flagged, not fixed: the generic matins-hymn-paschaltide.yml will incorrectly render during the Ascension octave specifically, which is live-verified to have its own genuinely different proper hymn ("...Qui scandis super sídera") not yet authored anywhere — same-shape gap already existing in Lauds' own lauds-hymn-paschaltide.yml, not a new regression introduced here.

Updated 2 FERIAL_DATE (2026-12-01, a Tuesday in Advent) hymn assertions in tests/hours/matins.test.ts that had been asserting Tuesday's own ferial text — Advent's own seasonal hymn correctly outranks the weekday cycle now. npm test (2025 passed) and tsc --noEmit both pass.

Ascension's own hymnody at Matins/Lauds/Vespers, plus the octave mechanism gap it exposed (2026-09-04)

User asked to actually close the Ascension-octave gap flagged in the entry just above. Turned out to be a genuine mechanism gap, not just missing content: ascension is a temporal-feast id (data/calendar/temporal-feasts/ascension.yml), not a saint record, so hours/resolve-common.ts's resolveOfficeWinner — which already synthesizes a sanctoral-shaped winner from an active octave's own saint record (how Assumption's/St. Lawrence's octave already gives every hour real content on interior days) — never recognized it at all. Ascension Day itself and its whole octave were silently rendering the generic Paschaltide hymn at every hour, live- verified against Divinum Officium (Monastic Tridentinum 1617, 2026-05-14, Ascension Day itself): real content is "Jesu nostra redémptio" (identical at Matins/Lauds/Vespers), Act 1:1-2 (Lauds/ Vespers' shared chapter), and two genuinely distinct Lauds/Vespers responsories ("Ascéndit Deus in jubilatióne" / "Ascéndens Christus in altum").

Fixed the mechanism two ways: (1) added ascension to ALWAYS_OVERRIDE_TEMPORAL_IDS (covers Ascension Day itself, the same way christ-the-king/circumcision/etc. already do); (2) taught resolveOfficeWinner to also synthesize a {kind: 'temporal'} winner from an active octave with no saint record but a real temporal-feast record — covers ordinary-feria octave days (a real saint still correctly keeps priority when one wins, e.g. St. Venantius/St. Peter Celestine within the octave, live-verified unaffected). A third gap surfaced testing this: octaveGoverningPrivilegedDay (the Sunday-side half of that same synthesis) has its own, separate, correct-by-design rule that a privileged Sunday never accepts even an octave override — but live-verified wrong specifically for "Dominica infra Octavam Ascensionis," which really does keep the octave's own hymn/responsory (just with its own distinct proper chapter, not touched here). Rather than loosen that shared gate (real risk of wrongly re-admitting some other octave's override on some other privileged Sunday, unverified case by case), gave Lauds' and Vespers' own hymn-resolution functions (resolveLaudsHymn/ resolveVespersHymn) a narrow, hymn-only intercept: check resolveActiveOctave directly (no privileged-Sunday gate) but only for a saint-less octave, before falling to the season/weekday default — leaves every saint-based octave's existing behavior (and every other hour/part) completely untouched.

Authored matins-hymn-ascension.yml, lauds-{capitulum,responsory,hymn,versicle}-ascension.yml, and vespers-{responsory,hymn,versicle}-ascension.yml (Vespers' own chapter already falls back to Lauds' via vespersCapitulumForOverride's existing cross-hour fallback, so no separate file needed) — all live-verified. Confirmed the whole octave end-to-end via resolveOrdo directly (Ascension Day, two plain ordinary-feria octave days, the Sunday within the octave, and 3 real winning saints within the window, all correct) rather than just the reference engine. npm test (2025 passed, no test changes needed) and tsc --noEmit both pass.

Flagged, not fixed: Ascension's own collect is still missing (getTemporalProper('ascension-collect') — a pre-existing gap, unrelated to and unaffected by this fix, not scoped to "hymnody"). Also flagged: Pentecost/Corpus Christi/Sacred Heart are the same shape (temporal-feast octaves with no saint record) and likely have the same latent hymn gap this fix closed for Ascension specifically — not checked or fixed here.

Follow-on, same day: per direct instruction ("Ascension and Pentecost are some of the most important material in the entire app — fix it"), closed Pentecost's own copy of the same gap immediately, rather than leaving it flagged. Live-verified against Divinum Officium (Monastic Tridentinum 1617), 2026-05-24 (Pentecost Sunday itself): unlike Ascension, Pentecost has 3 genuinely different hymns, one per hour ("Jam Christus astra ascénderat" at Matins, "Beáta nobis gáudia" at Lauds, "Veni Creátor Spíritus" — yes, that one — at Vespers), each with its own real, distinct chapter/responsory/versicle at Lauds vs. Vespers. Added pentecost-sunday to ALWAYS_OVERRIDE_TEMPORAL_IDS (the mechanism fix from the Ascension entry above is generic — no code change needed beyond that one line) and authored matins-hymn-pentecost-sunday.yml, lauds-{capitulum,responsory,hymn,versicle}-pentecost-sunday.yml, and vespers-{responsory,hymn,versicle}-pentecost-sunday.yml. Confirmed the whole octave end-to-end via resolveOrdo (feast day, plain octave days, and a real winning saint within the window — St. Augustine of Canterbury, live-verified unaffected, keeps his own hymn at Lauds/Vespers while Matins keeps Pentecost's own per the same established generous-octave design already used for Assumption/ Ascension). npm test (2025 passed, no test changes needed) and tsc --noEmit both pass.

Corpus Christi and Sacred Heart remain the one still-open piece of this same-shape gap — not fixed this session, lower priority than Ascension/Pentecost per direct instruction.

Follow-on, same day: per direct instruction ("ascension's collect and the two octaves"), closed all 3 remaining pieces immediately.

Authored ascension-collect.yml (live-verified 2026-05-14) — a separate, pre-existing gap (getDayCollect already looked up ascension-collect via the same resolveOfficeWinner this session's mechanism fix already covers; the collect file itself just never existed).

Closed Corpus Christi's and Sacred Heart's own hymnody gaps the same way as Ascension/Pentecost: added corpus-christi and sacred-heart to ALWAYS_OVERRIDE_TEMPORAL_IDS (no further code change needed — the mechanism is generic) and authored matins-hymn-{corpus-christi,sacred-heart}.yml, lauds-{capitulum,responsory,hymn,versicle}-corpus-christi.yml, vespers-{responsory,hymn,versicle}-corpus-christi.yml, lauds-{capitulum,hymn,versicle}-sacred- heart.yml, and vespers-{hymn,versicle}-sacred-heart.yml — all live-verified against Divinum Officium, 2026-06-04 (Corpus Christi) and 2026-06-12 (Sacred Heart). Corpus Christi's own hymns are widely known outside this context too: Matins' own "Sacris solémniis", Lauds' own "Verbum supérnum pródiens" (whose final 2 stanzas are the separately-famous "O Salutaris Hostia"), and Vespers' own "Pange, lingua, gloriósi Córporis mystérium" (whose final 2 stanzas are the separately-famous "Tantum Ergo").

Sacred Heart needed one real source-track correction: the Monastic Tridentinum 1617 track doesn't observe this feast on this date at all (live-checked: shows St. Barnabas instead, a real 1617-era calendar gap, not a vu bug) — used Divino Afflatu 1954 instead, consistent with this project's own stated rubric/precedence track (see CLAUDE.md). Also live-verified a genuine, deliberate structural difference: Sacred Heart's own Lauds and Vespers have no responsory at all in the source (straight from chapter to hymn, "Capitulum Hymnus Versus" with no "Responsorium" between) — not an authoring gap, so no lauds-responsory-sacred-heart.yml/vespers-responsory-sacred-heart.yml were created. This exposed a real small UI gap: hours/lauds.ts's and hours/vespers.ts's own resolveOffice always pushed a {kind:'responsory'} part even when its own resolved text carried status: missing in both languages, rendering an empty section. Fixed both to omit the responsory part entirely when both languages are genuinely missing, rather than an empty box.

Confirmed both octaves end-to-end via resolveOrdo (feast days, plain octave days, and real winning saints within each window — St. Boniface/St. Barnabas within Corpus Christi's, unaffected). Found and fixed 2 pre-existing tests whose own dates now land inside these newly-modeled octaves and were asserting the old (buggy) fall-through behavior as if correct: tests/hours/lauds.test.ts's FERIAL_MONDAY (was 2026-06-08, inside Corpus Christi's octave — moved to 2026-09-07) and tests/hours/vespers.test.ts's own St. Margaret of Scotland test (2026-06-09, also inside Corpus Christi's octave — its own title already anticipated this exact fix; updated its assertions from the old "falls through to the plain ferial default" guess to the real, live-verified Corpus Christi content). npm test (2025 passed) and tsc --noEmit both pass.

Recombined the 5 remaining Ember-day nocturn-readings files (2026-09-04)

User asked "why only Wed/Sat in September?" after the earlier Ember-Friday recombine, then asked for all the remaining smaller gaps to be closed. Checked the reference source directly for each of ember-september-wednesday/ember-september-saturday/ember-advent-wednesday/ember-advent- friday/ember-advent-saturday (all 5 still carried the original "genuinely distinct proper responsory" split rationale) and confirmed all 5 are the same shape already fixed for Ember Friday: one continuous, unbroken homily (Bede, Gregory, or — for the two Advent Wednesday/Friday cases — Ambrose's Commentary on Luke, cross-referenced from the Annunciation's own Common, @Sancti/03-25:Lectio7/8/9, confirmed contiguous by reading the source file directly), split only to fill the fixed 3-lesson slot count. Recombined all 5 into single readings, same convention as before (keep the first lesson's own responsory, drop the rest). Updated tests/calendar/ember-days.test.ts's lesson-count table (now 1 for all 6 Ember days, was a mix). npm test (2025 passed) and tsc --noEmit both pass.

Lent's own Lauds capitulum/responsory/versicle: not homeless after all (2026-09-04)

The "homeless Isa 58:1 / Ipse liberávit me / Ángelis suis" content flagged in an earlier entry (believed to have no home after the Marian-Saturday/plain-ferial-Saturday content correction) turned out to already have a real home: lauds-capitulum-lent.yml/lauds-responsory-lent.yml/ lauds-versicle-lent.yml already existed with this exact content, just marked draft (never live-verified) rather than genuinely missing. Live-verified against both a Lenten Ember Saturday (2026-02-28) and a plain Lenten Wednesday (2026-03-04) — identical, confirming this is genuinely season-wide content (not weekday-varying) and correcting an earlier session's wrong "homeless" claim. Marked all 3 files verified. (Vespers' own Lenten capitulum/responsory/versicle/hymn and both hours' Lenten hymn-doxology-per-annum files are still draft — a separate, broader Lent-content verification backlog noticed in passing, not fixed here, out of scope of what was specifically flagged.)

Trinity Sunday: a real feast, not modeled at all (2026-09-04)

A third "smaller gap" turned out much bigger on inspection: what had been described as a "Trinity Sunday display gap" was actually a missing calendar mechanism. getDayLabel already had a purely cosmetic "Trinity Sunday" label overlay for the Sunday after Pentecost, but nothing made that Sunday actually be Trinity Sunday — resolveTemporalId just fell back to post-pentecost-01, an ordinary-sunday category, so any Duplex+ saint assigned that date (e.g. the Queenship of the BVM, 1954, fixed May 31) won outright per the normal rule, with Trinity Sunday itself never appearing as more than a commemoration or a cosmetic label. Live-verified against Divinum Officium (Monastic Tridentinum 1617, 2026-05-31): the real occupant is "Festum Sanctissimæ Trinitatis, Duplex II. classis" — one of the year's principal Sundays.

Added a real data/calendar/temporal-feasts/trinity-sunday.yml record (Easter+56, Duplex II. classis). Per direct instruction, unconditional: true (same shape as christ-the-king.yml) — Trinity Sunday always wins, since the one real collision case (the Queenship of the BVM, also Duplex II classis, fixed May 31) isn't independently live-verifiable against the Monastic 1617 track at all (that calendar doesn't carry the Queenship feast — May 31 there is St. Petronilla instead, confirmed live), and a principal Sunday shouldn't lose a same-rank fixed-date collision by coincidence.

Authored the full office: trinity-sunday-collect.yml, trinity-sunday-{benedictus,magnificat}- antiphon.yml, matins-hymn-trinity-sunday.yml ("Summæ Deus cleméntiæ" — shares its opening stanza with the plain ferial Saturday hymn but diverges completely after that, a genuinely different hymn), lauds-{capitulum,responsory,hymn,versicle}-trinity-sunday.yml, and vespers-{responsory,hymn, versicle}-trinity-sunday.yml (Lauds/Vespers share both their chapter, via the existing cross-hour fallback, and their hymn, "O lux beáta Trínitas" — already the pre-Urban VIII text) — all live- verified 2026-05-31. Added trinity-sunday to ALWAYS_OVERRIDE_TEMPORAL_IDS.

Found and fixed 3 pre-existing tests written around the old cosmetic-label behavior, two of which had never-verified guesses baked in as if correct: tests/calendar/day-label.test.ts's "names the anchor day itself" test (now Trinity Sunday wins outright over the Queenship, not the reverse) and its own "outranks an active octave" test (previously asserted "Duplex I Class", a guess — the real, now live-verified rank is Duplex II Class); tests/calendar/transfer.test.ts's St. Felix I test (Trinity Sunday now the real winner on 2026-05-31, Queenship/post-pentecost-01/Pentecost's octave all commemorated in return). npm test (2025 passed) and tsc --noEmit both pass.

Lent's remaining Vespers/Lauds draft content, verified (2026-09-04)

Closed the rest of the "Lent's own seasonal office bundle" gap flagged in the entry above the same day: vespers-{capitulum,responsory,hymn,versicle}-lent.yml and both hours' own -doxology-per-annum files were all real content, just never marked verified. Live-verified Vespers' own bundle against a plain Lenten Wednesday (2026-03-04) — Joel 2:17 chapter, "Scápulis suis obumbrábit tibi" responsory, "Audi, benígne Cónditor" hymn (including its own claimed Monastic word-swap, confirmed live), shared "Ángelis suis" versicle. lauds-hymn-lent.yml's own content ("Jam Christe sol justítiæ") and its doxology were already seen live earlier the same session (while checking lauds-hymn-saturday.yml's real content against the same 2026-02-28 Lenten Ember Saturday date) — byte-identical, just needed the status flipped. All 8 files now verified; no more draft Lent content anywhere in this app. npm test (2025 passed) and tsc --noEmit both pass.

Paschaltide's "Suffragium Paschale" mechanism (2026-09-04)

Closed the highest-priority remaining mechanism gap. Live-verified against Divinum Officium (both Monastic Tridentinum 1617 and Tridentine 1906, byte-identical between the two tracks — the source's own [Suffragium] macro literally has a (sed tempore paschali) @:Suffragium Paschale override, 2026-04-20, a plain Eastertide feria): throughout the whole Paschaltide window (eastertide/ ascensiontide/pentecost — the same boundary PASCHALTIDE_SEASONS already governs elsewhere in this store), two things happen whenever they'd otherwise show at all:

1. The ordinary 5-suffrage set (Cross/BVM/Joseph/Apostles/Peace) collapses into one single alleluia-form "Suffragium Paschale" block — one antiphon (different at Lauds, "Crucifíxus surréxit a mórtuis...", vs. Vespers, "Crucem sanctam súbiit...", unlike the ordinary 4/5 suffrages, which share identical text at both hours), one shared versicle, one shared collect.
2. The ferial-Preces litany (lauds-preces-feriales/vespers-preces-feriales, sourced from Tridentine 1906/1910 since Monastic 1617 has none at all — see that file's own header) drops entirely rather than being replaced by anything ("Preces Feriales{omittitur}" live) — a Sunday/feast's own short litany (lauds-short-litany) is untouched, a separate, universal collect-opening dialogue unrelated to this ferial-specific one.

Exported a new isPaschaltide(season) helper from hours/resolve-common.ts (wraps the existing PASCHALTIDE_SEASONS set, previously private to that file) and used it in both resolveSuffrages (gated after the pre-existing "omit suffrages entirely" checks — Double+/active octave/Advent-Christmastide-Passiontide already drop suffrages regardless of season, unaffected) and a new check in hours/lauds.ts's/hours/vespers.ts's own 'lauds-preces'/'vespers-preces' cases (gated on isFerialOrVigil(day), matching the existing predicate that already selects the ferial litany in the first place). resolveSuffrages gained a third hourId: 'lauds' | 'vespers' parameter (both call sites updated) to pick the right antiphon.

Authored lauds-suffrage-paschale.yml and vespers-suffrage-paschale.yml — English on the Vespers antiphon is this project's own translation and left draft (the reference engine's own English render leaves that one antiphon untranslated, Latin-only); everything else verified.

Verified end-to-end via resolveOrdo on real dates for Lauds (both the suffrage collapse and the Preces omission fire together correctly on a clean Eastertide feria, 2026-04-20) and via a direct resolveSuffrages unit call plus a separately-found clean Vespers evening (2026-04-15, since this particular stretch of Eastertide 2026 is otherwise densely packed with First-Vespers anticipations and octaves — Easter's own, the Patronage of St. Joseph's, Ascension's, Pentecost's — that already correctly suppress suffrages for other, pre-existing reasons and would have made a false negative look like a false positive). npm test (2025 passed, no pre-existing tests exercised this path at all) and tsc --noEmit both pass.

Matins responsory pools: per-book expansion + new per-Common-category pool (2026-09-04)

User request: real Matins responsories for each Bible book (sourced from the reference engine), and for the patristic (Nocturn 2/3 homiletic) readings too. Investigation found the patristic side was a much bigger, previously-untracked gap than the per-book pool's own "expand beyond isa" item already on this list: 272 of 355 data/propers/nocturn-readings/*.yml files have no responsory field at all — most of the calendar, not a handful of stragglers.

Per-book pool (data/hours/matins-responsories-by-book.yml): added gen (2 entries, Latin/ Tempora/Quadp1-1.txt — Monday of Septuagesima week, the historical start of the Genesis "Historia" cycle, a plain ferial with no overriding feast; only 2 entries because the source's own English translation is missing a 3rd) and jer (3 entries, Latin/Tempora/Quad6-2.txt — Tuesday of Holy Week, "Feria privilegiata," genuine ferial Jeremiah/Lamentations content). Deliberately did not seed jer from Pent02-5.txt despite it citing Jeremiah too — that day's Rank is Sacred Heart (Duplex I classis), so its Responsory1-3 are the feast's own proper text, not genuine ferial-book content, even though its Lectio verses are borrowed from Jeremiah. Still only 3 of ~66 books used in the user's own bible-plan seeded (isa, gen, jer) — the rest is deferred bulk content, one real live-sourced query per book, same pattern.

New per-Common-category pool (data/hours/matins-responsories-by-common.yml + getResponsoryForCommon in src/propers/matins-responsories.ts, sibling to the existing getResponsoryForBook): keyed by SaintRecord.common instead of a scripture book, same "loose match, cycle by index" design. Unlike the per-book pool (scattered one query per book, across the whole liturgical year), a Commune category's responsories live in one static file each (divinum-officium-reference's web/www/horas/{Latin,English}/Commune/CN.txt) — 9 files (C1-C8, C11) transcribed directly, cover all 19 of vu's real common: category ids (several are genuine aliases, confirmed by reading each candidate file's own @Commune/CX inheritance line rather than guessed — e.g. common-of-a-confessor-doctor/-pope inherit C4 unchanged, same pool as common-of-a-confessor-bishop; common-of-an-abbot/-not-bishop/several-confessors inherit C5 unchanged; common-of-a-martyr inherits C2 unchanged; common-of-a-virgin inherits C6 unchanged; common-of-a-widow/several-women-martyrs inherit C7 unchanged — see the data file's own header for the full mapping). Not seeded: common-of-an-angel/-an-evangelist/-a-vigil and the proper-to-* ids — none of these are real Commune categories with a responsory file to source from (angels/evangelists have their own proper content instead).

Wired into hours/matins.ts's nocturnReadingPart/gospelReadingPart: when a reading's own responsory field is absent, falls back to getResponsoryForCommon(getSaintRecord(id)?.common, index) — index is the reading's position within that same id's own file (a new commonPoolIndex counter in buildReadingPool's assembly loop), so a saint with several undated readings still gets distinct responsories across them rather than the pool's first entry repeated. A temporal/octave id (no common category) still correctly gets undefined — an honest absence, not a wrong guess.

Live-verified end-to-end via resolveOrdo: St. Francis de Sales (2026-01-29, common-of-a- confessor-bishop, previously responsory-less) now resolves a real Nocturn 3 responsory; Ss. Cornelius and Cyprian plus Ss. Euphemia, Lucy, and Geminianus (both on 2026-09-16, both common- of-several-martyrs) each resolve their own responsory from the same pool, confirming the per-saint-file cycling index doesn't leak across different saints sharing a day. npm test (2025 passed) and tsc --noEmit both pass.

Matins responsory pools: 8 more books seeded (2026-09-04)

Follow-up to the same-day entry above, continuing the per-book pool's bulk-content pass — same "one real source per book" method, no mechanism changes. Added exod (Latin/Tempora/Quad4-0.txt, Sunday IV in Lent, its own ordinary rank — the burning bush through the Song of the Sea), prov (081-1.txt, August week 1's own ferial), tob (093-0.txt, September week 3's own Sunday), ezek (111-1.txt, November week 1's own ferial), and 1macc (101-1.txt, October week 1's own ferial) — all bilingual, all genuinely their own book's content, no overriding rank.

Also added sir and sap (identical to prov's own entries) and dan (identical to ezek's) — not guessed reuse, confirmed by reading each week's own reference-engine file: the August "Wisdom literature" weeks (081 Prov, 083 Sap, 084-085 Sir) and the November "prophetic" weeks (111 Ezek, 113 Dan) @-reference the same underlying responsory set regardless of which specific book that week's Lectio actually reads that day — a real confirmation, from the reference engine's own data, that this app's "loose, book-level match, not exact-citation" responsory design (see the pool's own header, and the 2026-08 user direction it's sourced from) matches how these responsories genuinely worked historically, not an invention to paper over a smaller pool.

Skipped, deliberately: 1sam (1 Reg) — every Pent01 week file's responsories are macro references (@:Responsory1_ (sed rubrica cisterciensis) ..., [Rule] Initia cum responsory) rather than literal text, needing the base macro template resolved with per-file substitutions to get real text; not worth the complexity for one book this pass. 2sam/1kgs/2kgs/2macc (2/3/4 Reg, 2 Mac) — real Latin responsories exist in every week's own file, but the reference engine's own English translation is entirely absent for all of them (checked every Post-Pentecost week each book appears in); left unseeded rather than guessing a translation, consistent with only seeding books that have real bilingual source text. zach/amos/agg (minor prophets) — same English-translation gap, but Latin is real and available (Latin/Tempora/114-4.txt, 115-4.txt, 115-5.txt) if a future pass wants to add an own-translation draft English side (see vu-prefer-text-over-missing memory for the precedent).

Now 11 of ~66 bible-plan books seeded: isa, gen, jer, exod, prov, sir, sap, tob, ezek, dan, 1macc. npm test (2025 passed) and tsc --noEmit both pass; live-verified via getResponsoryForBook resolving real text for every new key.
