Now 0 gaps over 9496 days (2025-2050); reading correctness spot-checks match missalemeum except the resumed-Epiphany-Sunday edge (next commit). - calendar.TemporalSlug: the green-season weekday-repeats-the-Sunday rule uses the Sunday's TEMPORAL slug, so a Monday still finds its Sunday Mass when that Sunday was displaced by a feast (e.g. the Purification on Feb 2). - Add the missing EF temporal Masses (from missalemeum): the Nativity Day Mass (Heb 1:1-12 / John 1:1-14), Epiphany (Isa 60:1-6 / Matt 2:1-12), the Octave Day of Christmas (Titus 2:11-15 / Luke 2:21), the 6th Sunday after Epiphany (1 Thess 1:2-10 / Matt 13:31-35), and the last Sunday after Pentecost (Col 1:9-14 / Matt 24:15-35). 2026-07-28T12:35:24Z Lukasz Kasprzak lukas@labunix.xyz 2026-07-28T12:35:24Z urn:sha1:a80e61963756a28a3963a0442a8ccc1572518373 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. 2026-07-28T08:47:48Z Lukasz Kasprzak lukas@labunix.xyz 2026-07-28T08:47:48Z urn:sha1:98fe454868ffff3f52396e095b5cd5f1251f1fd2 Mary, Mother of the Church and the Immaculate Heart of Mary are computed in the engine (no fixed-date INI entry), so they fell back to the ferial. Attach their proper Masses inline: Mary MotC = Gen 3:9-15,20 / Ps 87 / John 19:25-34; Immaculate Heart = Isa 61:9-11 / 1 Sam 2 canticle / Luke 2:41-51. Verified they render when observed (Immaculate Heart 2029-06-09).

Extraordinary Form: - Capture fixed-date vigils in the sanctoral harvest (Christmas, the Nativity of St John the Baptist, Sts Peter & Paul, St Lawrence, the Assumption, All Saints, the Immaculate Conception) -- previously filtered out. - temporalEF: the movable vigils of the Ascension (I class eve) and Pentecost (Whitsun Eve), and the September/Advent Ember days (II class violet ferias). - transferIfImpededEF: the Annunciation transfers past Holy Week/the Easter octave to the Monday after Low Sunday; All Souls moves to Nov 3 when Nov 2 is a Sunday. - genlect harvests proper Masses for the new Ember/vigil days.
