fix(ef): ubaldus and didacus are III-class feasts, not commemorations

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.

The defect became visible only against witnesses outside that tree -- the Missal's own RG 128 (already transcribed in the register since 2026-08-11, and disagreeing with the shipped data all along), O'Connell, and a published 1962 Ordo. The Ordo is what first flagged the Assumption vigil; O'Connell is what found St Lawrence's, which the Ordo could not give because that source omits the vigil entirely. Gated on the two literal slugs and diffs = [Colour_f] exactly, so a future identity or rank divergence on either day would NOT be absorbed here. 77, not 92: over the fixture's 2005-2050 span each vigil has 46 possible occurrences, and 15 are impeded outright (the vigil yields when its own date falls on a Sunday), so those rows never reach this entry -- both engines agree on the Sunday. Derived from the OCaml comparator's own output, not hand-counted.")

+ (citation "The 1962 Missal's own universal CALENDARIUM, which is the universal calendar of the Roman rite -- it carries no 'pro aliquibus locis' marker anywhere in its 573 lines, while the wider Missal carries 79 of them elsewhere, so an entry appearing in it is universal by construction. 16 May: 'S. Ubaldi Ep. et Conf., III classis' (docs/research/scan1.txt:2801), corroborated scan2.txt:3197 ('16 S. Ubaldi Ep. et Conf., III cl.'). 13 November: 'S. Didaci Conf., III classis' (scan1.txt:3091), corroborated scan2.txt:3532 ('S. Didaci Conf., III cl.'). Neither carries a Commemoratio rubric; both are bare III-class feasts. Each also has its own Mass entry in the Proprium Sanctorum -- 'Die 16 maii / S. Ubaldi Ep. et Conf. / III classis / Missa Statuit, de Communi Confessoris Pontificis I loco [19], praeter orationem sequentem' (scan1.txt:30196, scan2.txt:33448) and 'Die 13 novembris / S. Didaci Conf. / III classis / Missa Iustus, de Communi Confessoris non Pontificis II loco [25], praeter orationem sequentem' (scan1.txt:40276, scan2 printing the same with its own pagination, '2 loco (26)') -- which a mere commemoration never has, a commemoration carrying only an oration. The published 1962 Ordo (register 6.21) independently lists both as the day's III-class office")

+ (note "ef-sanctoral-status branch. Both entries carried rank Class3 with status Commemoration_only, bootstrapped from lectio, which inherits it from missalemeum, which is generated from Divinum Officium -- the same single lineage C37 documents. Found by auditing ALL 290 fixed-date sanctoral entries against the Missal's own calendarium, day by day, anchored on the Roman calends column rather than the OCR-mangled arabic day numbers; ubaldus and didacus were the ONLY two status defects in the whole file, and the 10 days the automated pass could not cover were checked by hand and all agree. That result also narrows a standing register claim: the recorded 'wrongly Commemoration_only' defect was described as a cluster in 6 March - 5 April, and neither of these falls in it, so the cluster was an artefact of where someone looked rather than the defect's extent. Neither saint needed a proper authored: each takes its Mass from a Common with only its own Oratio proper, so this is an assignment in data/ef/commons.sexp, one of them to a Common newly transcribed for it (common-of-a-confessor-not-a-bishop-2, 1 Cor 4:9-14 / Luke 12:32-34, read independently in both scans). 70 rows over 2005-2050, in TWO exact diff shapes the predicate spells out separately rather than collapsing: 32 for ubaldus, where 16 May falls in Paschaltide and the ferial colour is ALREADY white so no colour difference arises, and 38 for didacus, where 13 November is green Time after Pentecost and the white confessor changes it. Not 46 each: the rest of the occurrences are impeded, or the saint loses to a competing office, and both engines then agree. Derived from the OCaml comparator's own output, not hand-counted.")
