fix(calendar): OF precedence/transfer + readings resolution; EF Pentecost octave

2026-07-28T12:35:24Z

Fixes found by validating the offline engine per-day vs the LiturgicalCalendar API (OF) and missalemeum (EF) across 2005-2050. OF calendar is now 0 real errors in the forward window (season/cycle already perfect). OF precedence/transfer (calendar): - Ash Wednesday and Holy Week Mon-Wed are band-2 privileged, so a coinciding feast (Chair of St Peter on Ash Wednesday) is suppressed, not observed. - Solemnities transfer out of Holy Week / the Easter octave: the Annunciation defers to the Monday after the 2nd Sunday of Easter; St Joseph is anticipated to the Saturday before Palm Sunday; the Nativity of St John the Baptist moves to Jun 23 when a Lord's solemnity (Sacred Heart / Corpus Christi) falls Jun 24. - Within a precedence band, a solemnity of the Lord/BVM outranks a saint's (dignity tiebreak) rather than losing an alphabetical slug tie. - Perpetua & Felicity corrected optional -> obligatory memorial. OF readings resolution (bible.OFRef + lectionary data): - Verse-accurate Hebrew->Vulgate psalm mapping incl. the split psalms (9/10, 114/115, 116, 147); "+" verse joins and abbreviated ranges ("127-28") normalized; single-chapter books (2/3 John, Jude) get chapter 1. - Cleaned harvest artifacts from of-lectionary.ini (descriptive-suffix gospels, "or Year A" alternates, "*"/"[Vulg.]"/bracket markers, slash abbreviations); Joel/Malachi/Zechariah/Esther book-versification citations fixed to Vulgate. - Split a merged Ps 15:10/11 row in vul.tsv. Result: 0 unresolvable OF readings over 2557 rendered days (cycles A/B/C, varied Easters). EF: the Octave of Pentecost (Whit Monday-Saturday) is red, not white.

feat(of): Christmas-season weekday ferials from catholic-resources.org (date-based)

2026-07-28T08:45:09Z

Completes the seasonal weekday lectionary. The Christmas-season weekdays sit on the AdventChristmas page in a SHIFTED 6-column layout (Day in c[1], not c[2] like Advent's 7-column) -- the generator now finds the Day column wherever it is. Adds date-based slugs to temporal.go: christmas-dec-<29..31> (octave), christmas-jan-<2..7> (before Epiphany), christmas-after-epiphany- (before the Baptism). Fixes the christmas-octave-fri coverage gap and the by-date/by-week collision. 362/362 seasonal ferial-days render across 2026-2029 with 0 gaps. Extends TestOFSeasonalFerials. All of Advent/Lent/Easter/Christmas weekdays now CR-sourced; only the Commons remain (optional -- memorials default to the ferial).

feat(of): seasonal weekday ferials from catholic-resources.org + date-based late Advent

2026-07-28T08:35:21Z

Re-sources the proper weekdays of Advent (weeks 1-3), Lent, and Eastertide from catholic-resources.org (scripts/genlect-of-season-ferials-cr.py; single-cycle, so both -I/-II keys get the same readings). The diff caught real niedziela defects: - Easter weekday first readings contaminated (easter-3-mon had 1 Cor 15 instead of Acts 6:8-15; easter-4-thu had Rev 12 instead of Acts 13:13-25). - The Easter octave weekdays (Easter Mon-Sat) had no readings at all. - Stray psalm-numbering artifacts (147A(146), Ps42(41)) cleared. Late Advent (Dec 17-24) is proper to the DATE, not the Advent week, so temporal.go now keys those days 'advent-dec-' (fixing the same by-date/by-week collision as the OT numbering) and the generator supplies them (Dec 17 = the genealogy Matt 1:1-17; Dec 24 = the Benedictus). 157 seasonal ferial-days render across 2026-2028 with 1 residual gap (christmas-octave-fri). Adds TestOFSeasonalFerials, credits the source, bumps to 0.43.0. Christmas-season weekdays (Dec 29-31, Jan 2-5) remain niedziela-sourced (CR's shifted layout + Epiphany-dependent assignment -- a documented follow-up).

fix(of): canonical OT ferial week numbering + CR-sourced ferial lectionary

2026-07-28T07:30:22Z

The Ordinary Form ferial lectionary had two linked defects, both from harvesting niedziela.pl by date: (1) post-Pentecost Ordinary-Time ferial WEEK NUMBERS were one too high (temporal.go counted back from Christ the King using the weekday itself, not its preceding Sunday, so a ferial took the next week's number), and (2) ~17 ferial keys held a SAINT's readings (stored when a saint displaced the ferial on the queried date, e.g. week 22 smeared with a Marian Prov 8/John 2), plus 16 weekday slots were missing entirely. - temporal.go: number a span-2 ferial from its preceding Sunday. Verified 388/388 ferial-week agreement with calapi across 2026-2028. - scripts/genlect-of-cr.py: regenerate the Ordinary-Time ferial lectionary (first/psalm/gospel, both years, all 34 weeks) from catholic-resources.org (Fr. Felix Just, S.J.), which is keyed by liturgical position (immune to by-date contamination) and complete. Citations only; text still rendered from the public-domain corpora. of-lectionary.ini OT ferials now 408 (was 392). Fixes ~17 contaminated entries + 16 gaps + the week-numbering audit item. Psalms already share modern numbering, so no conversion. Adds TestOFOrdinaryTimeFerialWeek. Credits catholic-resources.org in NOTICE. Bumps to 0.40.0.

test(calendar): regression oracle vs calapi 2020-2040 (0 season mismatches)

2026-07-27T10:33:47Z

Caught + fixed an Advent-start bug: anchor on Christmas Eve, not Dec 25, so years where Dec 25 is a Sunday don't lose the first week of Advent. Rank-class diffs (324) are informational — the initial sanctoral dataset is partial.

fix(calendar): Christmas solemnity in temporal; feasts of the Lord band 5; Sunday band before solemnity-rank fallback
