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 2026-08-18T10:11:05Z 2026-08-18T10:11:05Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T10:11:05Z urn:sha1:a6daed7820a97f4032f21964b5b1bb30fe00b36b Both carried rank Class3 with status Commemoration_only, bootstrapped from lectio, which inherits it from missalemeum, which is generated from Divinum Officium. The Missal's own universal calendarium ranks both "III classis" outright, with no commemoration rubric: "S. Ubaldi Ep. et Conf., III classis" (16 May) and "S. Didaci Conf., III classis" (13 November), corroborated in the second scan and in a published 1962 Ordo. Universal by construction, not by assumption: the calendarium carries no "pro aliquibus locis" marker in its 573 lines while the wider Missal carries 79 of them elsewhere. Each saint also has his own Mass entry in the Proprium, which a bare commemoration never has -- a commemoration carries an oration only. Found by auditing ALL 290 fixed-date entries against that calendarium, day by day, anchored on the Roman calends column because the arabic day column is OCR-wrecked and the dominical-letter column vanishes in some months. These two were the only status defects in the whole file. The 15 days the automated pass could not cover were read by hand and all agree. Neither needed a proper authored: each takes its Mass from a Common with only its own Oratio proper, per its own rubric at its own date. ubaldus shares patrick's Common exactly. didacus needed one newly transcribed -- common-of-a-confessor-not-a-bishop-2, the "Altera Missa" Iustus, 1 Cor 4:9-14 and Luke 12:32-34, read independently in both scans, which agree, so the page-image third reading this file's method requires on disagreement was not triggered. Blast radius, full 1583-9999 sweep, every day classified: 13 036. That is 5 564 ubaldus observed, 7 196 didacus observed, and 276 where the Ascension Vigil still wins on 16 May but its single RG 111(c) slot passes from rogation-wednesday to ubaldus -- correct and already pinned, since the Rogation days are the MINOR Litanies and so an ordinary commemoration, which RG 113's table order ranks below a III-class feast. Cited as C38 (70 rows) and M30 (3); C8, C17 and M18 shrink accordingly, each with the reason recorded rather than the count silently adjusted. 2026-08-14T23:40:54Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-14T23:40:54Z urn:sha1:1299815ea03c2b1e4ff19d92d32e386fec24f4e4 Fifteen class-3 saints had no readings anywhere in colitur -- the 6 March - 5 April cluster whose RANKS lectio's generator fix of 2026-08-12 restored without backfilling readings, and lectio has no Commons concept to have backfilled them from. They are exactly the fifteen `status Feast` entries in data/ef/sanctoral.sexp carrying `(citations ())`. The Missal splits them eight/seven, and NOT as the plan predicted. It expected propers for Benedict, Patrick, Thomas Aquinas and Gregory the Great; only Thomas Aquinas has one. Benedict ("Missa Os iusti, de Communi Abbatum"), Patrick ("Missa Statuit, de Communi Confessoris Pontificis I loco") and Gregory the Great ("Missa Si diligis me, de Communi unius aut plurium Summorum Pontificum") are all sent to a Common, with only Oratio, Secreta and Postcommunio printed at the date. All three reversals verified on the page images (pp. 488, 492) as well as in both OCR text layers. PROPERS (data/ef/adjustments.sexp, `Edit ... Set_citation`): thomas-aquinas 7 Mar Sap 7:7-14 / Mt 5:13-19 john-of-god 8 Mar Eccli 31:8-11 / Mt 22:34-46 forty-holy-martyrs 10 Mar Hebr 11:33-39 / Luc 6:17-23 cyril-of-jerusalem 18 Mar Eccli 39:6-14 / Mt 10:23-28 gabriel-the-archangel 24 Mar Dan 9:21-26 / Luc 1:26-38 john-damascene 27 Mar Sap 10:10-17 / Luc 6:6-11 john-of-capistrano 28 Mar Sap 10:10-14 / Luc 9:1-6 francis-of-paola 2 Apr Philipp 3:7-12 / Luc 12:32-34 COMMONS (data/ef/commons.sexp), each quoting the Missal's own instruction at the saint's date: sts-felicitas-perpetua 6 Mar non Virginum I Eccli 51:1-8,12 / Mt 13:44-52 frances-rome 9 Mar non Virginum II Prov 31:10-31 / Mt 13:44-52 gregory-the-great 12 Mar Summ. Pontificum 1 Petri 5:1-4,10-11 / Mt 16:13-19 patrick 17 Mar Conf. Pont. I Eccli 44:16-27;45:3-20 / Mt 25:14-23 benedict 21 Mar Abbatum Eccli 45:1-6 / Mt 19:27-29 isidore-of-seville 4 Apr Doctorum 2 Tim 4:1-8 / Mt 5:13-19 vincent-ferrer 5 Apr Conf. non Pont. I Eccli 31:8-11 / Luc 12:35-40 Every value read in three independent places -- both OCR text layers (two DIFFERENT printings, whose Commune Sanctorum pagination differs by 1-2, so the data keys on heading plus Mass incipit and never on the bracketed page number) and the rendered page images. That caught a genuine typographical error in one printing: it gives St Gabriel's Gospel as "Luc. 2, 26-38" (on the page image, so not an OCR artefact). Luke 1:26-38 is settled by the other printing, by the pericope text in both, and by the SAME edition citing the identical pericope correctly two pages later at the Annunciation. Step 4 EXECUTES SECOND (order 1, 4, 2, 3), not last as the plan sketched. Measured: every day on which one of the fifteen is actually the observed office already has a non-empty step-2 or step-3 answer waiting, so a step 4 placed after the ferial fallback is unreachable on every date in 1583-9999 -- and wrong where it would fire (2038-03-06 would emit Septuagesima II Saturday's Mass on a day whose office is Sts Perpetua and Felicity). Step 4 is also the only step in the chain with a direct primary-source warrant: the Missal names the Mass at each such saint's own date, while steps 2 and 3 rest only on lectio's observed behaviour. Guarded so it can never divert a day whose observed office IS its temporal office -- ferias, Sundays, the Triduum and the RG 78 Saturday Office of the BVM (which deliberately shares the ferial slug) are structurally excluded. Step NUMBERS are unchanged so every "step 3" already written down still names the same branch. The Commons are caller-supplied, like the lectionary: `Rite_ef.context` gains a REQUIRED `~commons`, not an optional one -- a silently-defaulted empty table would give a rite whose class-3 saints quietly lose their Mass, and nothing in layers 3-5 compares citations, so that loss would be invisible. `Commons.load` rejects the four defects indistinguishable downstream from "this saint has no Common": duplicate common id, duplicate assignment, empty formulary, assignment naming a common that does not exist. KNOWN LIMITS, recorded rather than papered over. There is no oracle: lectio has no readings for these feasts and missalemeum's 2026-2027 window never observes one of the fifteen. Eight of the fifteen are NEVER the observed office anywhere in the domain (10-28 March always falls to a Lenten or Passiontide feria that outranks a III-class feast), so they have no end-to-end witness and are covered by dedicated table tests instead. The Commune Sanctorum's own opening rubric permits any Epistle or Gospel of a Common in any Mass of that Common unless one is assigned, so what is emitted is the reading PRINTED WITH the named formulary, not the only lawful one; labelled alternatives (e.g. the widow's Epistle 1 Tim 5:3-10, squarely available to St Frances of Rome) are noted in the data and deliberately not encoded. The BVM Common is NOT authored: the RG 78 Saturday Office shares the ordinary ferial slug, so assigning a Common to it would hand the BVM Mass to every feria sharing that slug; routing it needs a subject-keyed lookup and a season-keyed choice among the Missal's five "Missae de sancta Maria in sabbato" -- new behaviour, not new data. It currently emits its feria's Mass, now pinned as such. Blast radius, measured (git archive HEAD binary vs HEAD, full 1583-9999 `colitur day` sweep, diffed): ZERO differing lines, 3 074 246 lines each side, byte-identical -- the CLI prints no citations, so this change is invisible to layers 2-5 by construction, and the sanctoral overlay perturbed nothing else. 357 tests green (344 before), 358 with the exhaustive sweep. Mutation-tested six ways, all reverted after confirming: relegating step 4 to last reddens exactly the four step-4 pins and nothing else; corrupting a Common's citation, dropping an assignment, dropping a proper Edit, and corrupting either an unreachable proper or an unreachable Common each redden their own pins. The load-bearing assertion is stated over the loaded layer rather than a hard-coded list: every sanctoral entry that can ever BE the observed office now has either a proper or an assigned Common -- fifteen failures before, zero after, and a future re-bootstrap adding a readingless class-3 feast fails there instead of silently emitting its feria's Mass.
