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=v0.3.0 2026-08-17T12:13:02Z 2026-08-17T12:13:02Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-17T12:13:02Z urn:sha1:3565ebd1608a7d87e0d890f9953845efcfe743ca A live-missalemeum sweep over a full liturgical year (2028, 364 days) returned 333 matching and 31 differing days: 17 already-known or pure notation, 3 new. All three now adjudicated against the photographic scans of the 1962 Missal. The Assumption's Epistle reads "Iudith 13, 22-25; 15, 10" (scan1:35357). Both engines carried "Judith 13:22-25; 13:15; 13:10" -- a chapter carry-over defect that re-applied chapter 13 to the second citation and so invented two verses the Missal never cites. The Seven Sorrows reads "Iudith 13, 22 et 23-25" (scan1:36938, corroborated at 28468); both carried "Judith 13:22; 13:25", dropping the range. The third, St Monica, resolves the other way: the Missal gives 1 Timothy (scan2:32679, heading and incipit both legible; scan1:29524 agrees) where missalemeum serves the Common of Holy Women's Proverbs -- colitur is right, no change. Layer 3 could not have found either citation defect. colitur's data is bootstrapped from lectio, and lectio is the other side of that differential, so while both engines produced the identical wrong answer the comparison held it against itself and reported agreement -- the shared-lineage blindness CLAUDE.md names, now with a second live witness beside Holy Thursday's colour. Only an external oracle could see it, and only outside the committed fixture's own window. Fixed upstream in lectio, re-bootstrapped here (provenance SHA-256 moved to 54f6bfc5, verified against the source), fixture regenerated. The upstream fix inverted layer 3 from blind to load-bearing here: reverting the Assumption citation now reddens both layers, where before it would have reddened neither. Verified by mutation, both directions. Allow-lists: - C22 closed and removed (128 rows -> 0), not re-adjudicated -- the other engine was fixed to agree, the same shape as the C2-C5/C7/C9-C13/C21 closures. Its own note had already flagged the Lenten Ember dead-key bug for upstream; lectio now also fails its build on any unreachable lectionary key rather than serving a plausible wrong Mass. - M28 opened (3 rows, verdict colitur), pinning both sides' citation text rather than the date and diff shape alone, so a different divergence landing on the same date cannot be swallowed. - M8's gate widened, expected_rows unchanged at 2: 2027-08-15 carries both its cause and M28's, and one entry is admitted per day. It stays under M8, which now requires its own commemoration difference to be present and admits the citation difference only when it satisfies M28's two-sided predicate. Neither cause absorbs the other. layer_m_reason's oracle-row parameter, kept named since M2 closed for exactly such a future reader, is live again.

On the celebration rather than in the lectionary table deliberately: a diocesan overlay adding a saint then carries his readings through the existing overlay algebra, with no second file to edit and no new directive. Asserted both ways -- the 13 January proper is present, and no Commemoration_only entry has readings, because in the EF a commemoration contributes an oration, not a reading. 2026-08-12T15:49:11Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-12T15:49:11Z urn:sha1:25fedcaf3044828333ba15b232fdc7c7f84970e5 Regenerated via tools/bootstrap_sanctoral.ml against lectio's tridentine-calendar.ini (SHA-256 6a25e634... -> 1b303ef2...), whose own generator was independently fixed in a concurrent session. 327 entries (223 feast, 104 commemoration-only), up from 322 (208/114): - 15 entries wrongly bootstrapped `rank = commemoration` are now `class-3` (a real III-class Feast) -- all 6 March-5 April, all primary-source-verified against the calendarium (register's own "Commemoration-only entries' inferred STATUS" item). - 5 new entries: agnes-secundo (28 Jan), boniface-martyr (14 May), eusebius-confessor (14 Aug), evaristus (26 Oct), theodore (9 Nov) -- all Commemoration_only, all primary-source-verified (register's "Four confirmed sanctoral DATA GAPS" item + expected-divergences-missalemeum .sexp's former M4/M6/M7/M9/M14). - commemoration-of-the-baptism-of-the-lord (13 Jan) is now `(subject Lord)` (the source's own `class` field, not a colitur overlay); most-holy-name-of-mary (12 Sep) no longer carries `class = lord` at all (the source dropped it), so the bootstrap default (Subject.Saint) is now correct there without help from adjustments.sexp's own Edit. test_sanctoral_ef.ml's pinned counts (327/104/12 Class1) are re-derived directly from the source INI (`grep -c '^\['`, `grep '^rank' | sort | uniq -c`), not transcribed from a bootstrap-tool or `colitur day` run. data/ef/adjustments.sexp and the differential/oracle allow-lists still need updating for the consequences of this regeneration -- follow-up commits. 2026-08-11T22:05:57Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-11T22:05:57Z urn:sha1:4624441d0bc9c1f28dea54606ab7999041d4b323 Convert lectio's tridentine-calendar.ini (322 entries) into data/ef/sanctoral.sexp via a validating OCaml converter, tools/ bootstrap_sanctoral.ml, rather than a hand-written script: every field is built through Slug.of_string, Colour.of_string and Vocab_ef.rank_of_string, so the emitted sexp is valid by construction. Two conversion decisions, both documented rather than buried: - subject defaults to Subject.Saint, overriding Celebration.make's kernel default of Subject.Temporal, for the 316 entries with no explicit class; - rank = commemoration maps to status = Commemoration_only with an inferred Class3 (not a citation -- it is what the 1960 reform reduced most simple feasts from), recorded as an open item in the rules register for the oracle to adjudicate. Every celebration is tagged layer = Precedence_ef.universal_layer, the provenance id RG 91's band classifier reads to tell the universal calendar from proper/indult data. The generated file carries a provenance header: source path, its SHA-256, and the UTC conversion date, so re-bootstrapping against a newer lectio is reproducible and diffable. Output is byte-identical across runs. test/test_sanctoral_ef.ml loads the file through Layer.load and checks the counts independently derived from the source INI (322 entries, 114 Commemoration_only, 12 Class1, no Subject.Temporal, every date resolves in a leap year), plus two named spot-checks against the INI's own text -- one entry with an explicit class field, one commemoration -- so a passing count cannot hide the wrong 322 entries having been converted.
