Two things, neither of them a day-level witness. Gated on lectio's own slug being one of the three vigils this clause can reach and colitur's not being a vigil -- identity on both sides, not a diff-set shape. The Assumption's and the Ascension's vigils are absent from that list because their I-class feasts always keep their own day: 0 occurrences across the whole domain, measured rather than assumed.")

Implemented in Rite_ef.Temporal_ef.bissextile_fixed_key, threaded through Colitur_kernel.Rite.t's new [fixed_key] field (bissextile-shift task, 2026-08-22).

A Sunday's own observed slug is unaffected by this shift either way, so whichever side coincides with one contributes nothing comparator-visible; only the other, non-Sunday side shows the real new divergence. 2024-02-24 is L3's own original date (data/ef/expected-divergences-lms.sexp), now confirmed independently by a second, larger fixture. + +GABRIEL (Class3, weaker than Matthias's Class2/Apostle rank) fires in only 2 of the 11 years (2028 occupied, 2044 vacated) because in the other 9 his position is already dominated by a Class3-or-stronger competing office both before and after the shift, so his own presence is commemoration-only throughout -- invisible to this comparator on either side. He surfaces only where the position happens to be a plain, unprivileged Class4 feria weak enough for his own Class3 to win outright: 2028-02-28 (colitur: gabriel-of-our-lady-of-sorrows, Class3, White, beating ef-septuagesima-3-monday, Class4) and 2044-02-27 (lectio still shows gabriel there unmoved, Class3, White; colitur's post-shift 27th falls to RG78's own votive BVM-Saturday office instead, also White, hence the colour match but slug/rank/citation mismatch in that row). Every one of the 21 rows was read directly off the comparator's own failure output, not apportioned by hand. + +Diff shapes: most rows carry [Slug_f; Rank; Colour_f; First_f; Gospel_f] (the temporal office on one side and the saint's own Class2/3 proper on the other differ in rank too); a handful carry only [Slug_f; Colour_f; First_f; Gospel_f] where the competing temporal office happens to share Matthias's own Class2 (the privileged Lenten Ember Friday/Saturday, 2024 and 2040) or Gabriel's own White (a BVM Saturday, 2044-02-27's own vacated row).
