docs(C39): day-level confirmation from the LMS Ordo

The Latin Mass Society Ordo 2024-2025 for England and Wales (v2.21,
compiled by Peter Day-Milne) gives 9 August 2025 as "OUR LADY on SATURDAY
IV Cl W / V Mass of BVM / Commem of St Romanus M at Low Mass" -- no vigil
-- and 10 August as the 9th Sunday after Pentecost with St Laurence
commemorated. That is colitur's output on both days, field for field.

It is discriminating where the Ordo already in docs/research was not. This
edition lists six vigils as the day's office across its year, including the
Assumption's on 14 August 2025, and its footnotes discuss arranging a
diocesan feast around the Vigil of St Laurence in other years. Its absence
on 9 August 2025 is an application of the rule, not a data gap. The
extraordinaryform.org Ordo omits that vigil on every date it covers,
including 2027-08-09 where the clause says to keep it, which is why it
witnesses nothing here.

Also confirms the Vigil of the Assumption as II Cl violet, the RG 128
colour this project corrected from the bootstrap's White.

The clause's other shape -- feast transferred away, 2022/2033/2038/2044 --
remains unwitnessed; no accessible Ordo covers those years. Stated in the
note rather than left implied.

 The same passage independently confirms vigil_feast_table's exact membership, which is the other thing no type can check: I class are Christmas Eve and Pentecost ('these take precedence of all feasts and admit no commemoration' -- RG 30, and why they are excluded from the table); II class are 'the eves of the feasts of the Ascension, the Assumption, the birthday of St. John Baptist (June 24), and SS. Peter and Paul (June 29)'; and 'there is only one vigil of III class, ie., the eve of the feast of St. Laurence (August 10)'. Five vigils, the same five, with the same class split the table encodes.

+DAY-LEVEL CONFIRMATION, 2026-08-21, from a second independent publisher. The Latin Mass Society Ordo 2024-2025 for England and Wales (v2.21, compiled by Peter Day-Milne, lms.org.uk, SHA-256 7c482684d177b2e1aa7498e302405bf37ee15042f892c65f7a6091fd5d169f7d, archived docs/research/ordo/lms-ordo-2024-2025.pdf) gives 9 August 2025 as 'OUR LADY on SATURDAY IV Cl W / V Mass of BVM / Commem of St Romanus M at Low Mass' -- no vigil -- and 10 August 2025 as '9th SUNDAY after PENTECOST II Cl G / Commem of St Laurence M at Low Mass'. That is colitur's own output on both days, field for field: the feast reduced to a commemoration on its own day, the vigil gone from the day before, and RG 78's votive Office of Our Lady taking the freed IV-class Saturday with St Romanus still commemorated.

+IT IS DISCRIMINATING, which the other Ordo was not. This edition lists six vigils as the day's office across its year -- the Nativity (I Cl V), the Ascension (II Cl W), Pentecost (I Cl R), the Nativity of St John the Baptist (II Cl V), SS Peter and Paul (II Cl V) and the Assumption (II Cl V, on 14 August 2025, five days after the date at issue) -- and its own rubrical footnotes discuss arranging a diocesan feast of St Oswald around the Vigil of St Laurence in other years, so it plainly knows and keeps that vigil. Its absence on 9 August 2025 is therefore an application of RG 33's third trigger, not a gap of the kind that made the extraordinaryform.org Ordo useless here (that one never shows St Laurence's vigil on any date it covers, including 2027-08-09 where the clause says to keep it).

+RIDE-ALONG CORROBORATION: the same entry gives the Vigil of the Assumption as 'II Cl V' -- violet -- independently confirming the RG 128 colour correction this project made on the ef-oconnell-rubrics branch, which had it White from the bootstrap.
+
+WHAT REMAINS UNWITNESSED is the clause's OTHER shape, the feast transferred away (2022, 2033, 2038, 2044 in this window). No accessible Ordo covering those years was found: the 1962ordo.today site keeps no archive, extraordinaryform.org publishes only 2024 onward, propria.org's archive refuses automated access, and the pre-1955 ordo that does cover 2033 is a different rubrical code with a Corpus Christi octave that impedes the day for an unrelated reason. The commemoration-reduced shape is confirmed; the transferred shape rests on the rule.
+
+WHAT O'CONNELL DOES NOT DO is witness the 10 DAYS. O'Connell states the rule; he publishes no day-by-day calendar, so the individual dates rest on the rule plus colitur's own occurrence machinery. The distinction is kept deliberately, because collapsing it is exactly the error the withdrawn Ordo paragraph above made.
 
 WHAT THIS ENTRY ALSO RESTS ON. Two things, neither of them a day-level witness. FIRST, the primary text, which admits no interpretive latitude: RG 33 joins three triggers with 'vel'/'aut' and the third is a plain conditional on the feast's own fate. SECOND -- and this is the substantive point -- lectio does not DISAGREE with the clause, it never evaluates it. 'RG 33' appears nowhere in lectio's production code, only in one test file's comments; its Sunday behaviour is emergent from ordinary rank comparison (a II-class Sunday outranks a III-class vigil), not from a transcribed rule. The third trigger cannot emerge that way at all, because it turns on what is observed the day AFTER, and a per-day precedence contest has no access to it. That is exactly why implementing it in colitur required a whole-year pass and a new field on Precedence.rules rather than a branch in disposition. So the divergence is architectural, not exegetical: on these 10 days lectio is not asserting that the vigil survives, it is producing the only answer its shape can produce. missalemeum and Divinum Officium inherit the same limit by lineage.
