+  (citation "RG 119 (Caput XVIII, \"De Colore Paramentorum\"): white is used \"in Officio et Missa de Tempore ... a Missa Vigiliae paschalis usque ad Missam vigiliae Pentecostes exclusive\" -- the de-Tempore Office and Mass are white from the Paschal Vigil Mass until the Pentecost Vigil Mass exclusive, and Rogation Monday/Tuesday (Easter+36/+37) sit inside that window. RG 128's own exhaustive four-case list for violet (Advent I-Christmas Eve; Septuagesima-Paschal Vigil; the September Ember ferias; vigils of II/III class OUTSIDE Paschaltide) never names Rogation days. RG 88 (\"de Litaniis minoribus nihil fit in Officio, sed tantum in Missa\"): the violet belongs to the Rogation MASS/procession, a distinct votive text this engine does not model, not to the day's own Office. Fixed in Rite_ef.Temporal_ef.temporal's Rogation branch, celebrant-rubrics-phase1 Bug 1, 2026-08-22 -- see that branch's own citation and data/ef/expected-divergences-lms.sexp's now-closed L6 entry, which is what surfaced it (LMS Ordo 2023-2024, 2024-05-06, \"FERIA IV Cl W\").")

+  (note "REOPENED (2026-08-22, celebrant-rubrics-phase1, Bug 1 fix). Previously CLOSED, REMOVED (2026-08-18): 0 of 16801 rows, was 26, with this note, PRESERVED VERBATIM because it contains a misattribution now corrected rather than silently dropped: \"lectio builds Rogation Monday and Tuesday now (RG 87, Easter+36/+37, violet under RG 128(d)). The Wednesday is NOT built there and deliberately so: Easter+38 is the Ascension's Vigil, which wins the day, and the rubric asks for a commemoration -- a channel lectio's one-office-per-day temporal function does not have. That is the same reason this entry never covered the Wednesday either. Citation preserved in the register.\"
+
+THE MISATTRIBUTION: \"violet under RG 128(d)\" is wrong. RG 128(d) governs vigils of II/III class OUTSIDE Paschaltide; Rogation Monday/Tuesday are neither vigils nor outside Paschaltide. Checked against docs/research/rules-register.md (gitignored, local) while researching Bug 1: no claim of an RG 128(d) basis for Rogation colour exists there -- the misattribution was confined to this file's own closure note. It traces to Rite_ef.Temporal_ef.temporal's own Rogation branch, which hardcoded [Colour.Violet] with NO citation at all before this fix; whoever wrote this entry's closure note in 2026-08-18 apparently backfilled a plausible-looking but wrong citation for behaviour that was never actually cited in the code it described.
+
+WHY THIS REOPENS RATHER THAN STAYS CLOSED: the entry closed in 2026-08-18 because lectio, independently, ALSO computes these two days violet -- not because either engine's violet was ever verified against the Missal. Both engines shared the same uncited assumption, so the comparator saw agreement and the entry went to zero. Bug 1 corrected COLITUR's side to white (RG 119); lectio's own violet is unchanged (a sibling project, out of this repo, not modified here). The comparator now disagrees again, on the same 26 rows, for the OPPOSITE reason: previously colitur was wrong and lectio was wrong the same way; now colitur is right and lectio still carries the old, uncited assumption forward -- consistent with CLAUDE.md's own \"colitur vs missalemeum\" base-rate note for a different lineage, applied here to lectio directly: a fresh divergence is not presumptively colitur's fault once colitur has just been corrected FROM the shared error.
+
+MEASURED (test_differential.ml's own [classify], 2005-2050 fixture, DEBUGC8 probe run and reverted): exactly 26 rows, all with diffs=[Colour_f] alone -- season and slug already agree (lectio's own [easter]/colitur's [paschaltide] season labels are Layer A vocabulary synonyms, not a diff), and on every row lectio=violet, colitur=white. Dates: 2005-05-03, 2006-05-22/23, 2007-05-14, 2011-05-30, 2012-05-14, 2013-05-06, 2016-05-03, 2017-05-22/23, 2018-05-08, 2022-05-23/24, 2024-05-06, 2027-05-03, 2028-05-22/23, 2029-05-08, 2032-05-03, 2033-05-23/24, 2040-05-08, 2044-05-23/24, 2047-05-21, 2049-05-24. Fewer than the 2-per-year x 23-year x ~2 ceiling because a competing sanctoral feast impedes the Rogation office outright in some years on one or both of the two days (unchanged by this fix, gated on colitur's own [rogation-monday]/[rogation-tuesday] slug in [layer_c_reason] the same as before). The Wednesday remains absent from this entry for the same reason the pre-2026-08-18 and post-2026-08-18 notes both already gave: Easter+38 is the Ascension Vigil (RG 91 entry 21), which outranks the Rogation Wednesday commemoration outright on colitur's side, and lectio has no Rogation-Wednesday concept at all to compare against regardless.
