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:

   • Easter's own octave — tabled, "a whole different discussion."
   • What "a Gospel reading is its own kind" should mean structurally/in the UI, beyond the isGospel flag on a plain Matins lesson — open; deferred until there's a UI to evaluate it against.

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: bible-plan TSV bulk conversion is done (see "Bible-plan TSV — bulk conversion done" below) — not yet added to a test table, though (unlike sanctoral/temporal content) there's no reference breviary to spot-check this plan against by design. Still open: author patristic/hagiographic readings for every saint where one can be sourced — no longer Duplex+-gated, content is pooled and shown regardless of rank (see "Reading-pool redesign"); expand the per-book Matins responsory pool beyond its one seeded book (isa). The pre-1955-but-post-1617 saints (Tridentine/Divino Afflatu-sourced, no Monastic 1617 track) are now done — see "Pre-1955 saints' Matins readings" below. The larger pool of saints that do have a Monastic 1617 track (SanctiM/) is now also done — see "SanctiM-track saints' Matins readings" below — all 12 months complete, 133 saints authored, the rest correctly left unauthored as Common-only/no-content cases.
   • The bulk Vulgate (Latin) + Douay-Rheims (English) scripture import into src/data/scripture/ — long-term project, explicitly deferred; Matins scripture citations resolve to missing text until it lands.
   • A handful of individually-flagged content gaps, each already flagged in place rather than silently dropped: St. Frances of Rome's and St. Bibiana's Benedictus antiphons (structurally can't win their own day under this app's calendar in any near-term year, needs a very late test year to check); Ss. Ursula and Companions' Benedictus antiphon (a category-of-one, no live rendering to verify against); the four "…benedícta…" octave-day Ant+V/R+collect blocks (not yet modeled). "Our Lady of the Snows" — formerly listed here as "not modeled at all" — is now added; see "Our Lady of the Snows added" below.

3. Known, deliberate simplifications — flagged as intentional, not a bug, no plan to revisit unless priorities change: see "Known, deliberate simplifications" at the end of this file, plus the Matins "Duo Seraphim" closing-responsory gap and the 5 Vespers hymns whose seasonal doxology substitution isn't modeled (both flagged in their own sections below, not repeated here).

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

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

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

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

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

Confirmed systemic bug, not just "unverified"

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

Method, worked out the hard way this pass

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

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

Progress

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

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

• All ~52 temporal entries: done, including christmas-octave-sunday (see the section above for method and its own correction).
• 94 propers: null saints: 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.

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).
• 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.

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.

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.

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.

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.

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

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