deterministic OCaml engine to compute and validate liturgical calendars for multiple rites, template-driven output to year 9999 https://git.labunix.xyz/colitur.git/atom?h=main 2026-08-23T21:01:42Z 2026-08-23T21:01:42Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-23T21:01:42Z urn:sha1:8faf89f89bd6783a518b6fc0b48c6ee452ba2e94 Extends tools/extract_lms_ordo.ml's row type with a praef field (the first "Pr of ..." / "Common Pr" match in each day's universal block, same first-in-reading-order discipline already used for Gl/Cr) and regenerates all three LMS fixtures. Also brings lms-ordo-2024-2025.sexp under the generalised, probe-verified provenance template the Witnesses task previously added only for the two newer editions -- it had kept Task 6's original hand-written header. Characterisation finding: this Ordo prints OPTION LISTS ("Pr of X or Pr of Y or Common Pr"), not a single value per day, and several named options (Martyrs, All Saints and Patron Saints, the Dedication of a Church, the Most Holy Sacrament, St John the Baptist, the Angels) are genuinely absent from RG 484-497's own fourteen named prefaces. Every instance found in the universal block pairs such an extra with a genuine RG-482 answer, so test/test_lms_ordo.ml compares by membership (classify_praef_options, a 15-entry prefix table split on the standalone token "or"), not string equality. Opposite-prediction probes (Nativity/Apostles/Requiem) are hard- verified inside the extractor itself before any fixture is trusted, the same discipline already used for the Creed column. Result: 396/396, 399/399, 398/398 comparable rows agree across the three editions (Good Friday excluded per edition, no Mass that day), zero allow-list entries needed. extraordinaryform.org's own three editions were characterised but deliberately not wired in this pass -- see .superpowers/sdd/2026-08-21-colitur-celebrant-rubrics-phase1/preface-witnesses-report.md for the full account (the field is genuinely per-day, contrary to a naive header-count read, but carries its own classification anomaly during Advent and reconfirms the corpus's known St Lawrence vigil defect, and building a full extractor for it is a separate, comparably large task not needed to decide the RG 497 question this same report settles).

Characterised before use, per the discipline the extraordinaryform.org Ordo's blanket St Lawrence vigil gap taught this session: five opposite- prediction Creed probes (Sunday/feria, octave-override vs plain II-class, I-class) all confirmed against the raw extracted text before a single divergence was adjudicated, recorded in the fixture's own provenance header. tools/extract_lms_ordo.ml hand-parses pdftotext -layout output (no Str/regex, frozen deps) into test/fixtures/lms-ordo-2024-2025.sexp, 400 day-rows (2024-11-27..2025-12-31). Gl/Cr print per Mass-option, not per day; the extractor takes the first pair in reading order, which the source's own layout guarantees is the universal entry's, since a diocesan variant always follows it, never precedes it. The Ordo's I-V roman numeral ("Missae de sancta Maria in sabbato", RG 309(a)) is matched whole-line only, never by substring -- "V Mass of BVM" is a substring of "IV Mass of BVM". test/test_lms_ordo.ml compares two axes 1:1 by date: - the Creed (RG 475-476): 399 of 400 days comparable (Good Friday has no Mass at all, asserted as the only such day); one genuine divergence, adjudicated to the ORDO, not colitur -- All Souls' Day 2025-11-03 is a Requiem Mass, and colitur's own creed predicate has no notion of one, a pre-existing scope gap rubrics_ef.ml already documented in its own header before this task existed. - the BVM-Saturday seasonal Mass selection, the addendum's own "sharper check": all 14 Votive days in the window match their season's own numeral exactly, both directions, independently re-derived from RG 309(a) rather than calling colitur's private function. - the formulary override, for the three sources it can honestly discriminate (Proper 179, Preceding_sunday 66, Common 2, all clean); Own_slug (139) is excluded with evidence, not silently -- several ferial slugs carry citations byte-identical to their Sunday's own, so the Ordo's override line cannot distinguish the two representations. data/ef/expected-divergences-lms.sexp carries the one adjudicated entry (L1), cited to RG 476(f). Mutation-tested: inverting RG 475(a)'s Sunday clause reddens 10 existing Rubrics_ef unit tests AND this new layer's own comparator, independently, on a data source none of the other five layers touch. Reverted after confirming. No lib/ changes. day/readings/rubrics output re-confirmed byte- identical (1583, 2026, 2038, 9999) after this task; all three gates green (dune test, exhaustive sweep, make check).
