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."

Content gaps — mechanism built, data incomplete

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

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

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

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

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

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

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

Same override id, separate files (lauds-capitulum-<id>.yml etc. in data/propers/common/) — falls back to the plain weekday bundle when absent, independently of whether the psalmody override exists. Right now only christ-the-king has this — St. Lawrence's own day shows his proper psalms but the plain ferial capitulum/hymn, which is inconsistent with what the live engine actually shows for him (2 Cor 9:6, his own hymn). Worth fixing even before tackling the other 32.

Benedictus antiphons for temporal (non-sanctoral) days

<id>-benedictus-antiphon.yml in data/propers/temporal/ — only marian-saturday and christ-the-king exist. Every plain numbered Sunday (52 of them) and feria is missing. Real practice has a proper antiphon for every one of these; not started, and it's a big pull if done exhaustively.

Octave collects

getDayCollects skips a kind: 'octave' commemoration entirely — no collect has ever been authored for an octave (the octave-reading pull only ever sourced Matins content). Every octave commemoration currently contributes zero text to Lauds'/Vespers' collect sequence.

Correctness risk — needs verification, not just authoring

Per-saint Benedictus antiphons may be sourced from the wrong rite

<saint>-antiphon.yml files (17 of them, see below) were pulled during the original sanctoral-content sessions, months before Lauds existed to consume them. Building St. Lawrence's psalmody override surfaced, by accident, that his had been read from the Roman/secular rite's [Ant 1], not Monastic 1617's actual Benedictus antiphon for that day — two genuinely different texts. Fixed for Lawrence. Not checked for any of the other 16:

apparition-of-st-michael, chair-of-st-peter-at-antioch, chair-of-st-peter-at-rome, conversion-of-st-paul, holy-innocents, nativity-bvm, nativity-of-st-john-the-baptist, ss-peter-and-paul, ss-philip-and-james, st-andrew, st-john-apostle, st-john-before-the-latin-gate, st-martin-of-tours, st-peter-ad-vincula, st-stephen-protomartyr, st-thomas-apostle.

Each needs a live command=prayLaudes query on the saint's own day (Monastic 1617) to confirm or correct — same check that caught Lawrence's.

The other 12 duplex-majus+ saints with propers set have no antiphon file at all yet (st-scholastica, st-matthias, st-matthew, st-mark, st-luke, st-james-the-greater, st-bartholomew, st-barnabas, ss-simon-and-jude, immaculate-conception, assumption, all-saints) — these don't have the wrong-rite risk, they just don't exist yet.

Mechanism not built at all

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

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

• getDayCollects: each collect in a multi-collect day renders as its own complete "Let us pray ... Amen." block, not the more compressed real form (one "Let us pray," only the last collect's doxology).
• Suffrage omission only checks omitOnDouble (+ Marian Saturday's own Cross/BVM filter, + Christ the King's explicit id check). Real seasonal suppression (e.g. during Advent/Lent) isn't modeled.
• 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).
