From 761ae859d73660bcfaa59581312989cb942e704d Mon Sep 17 00:00:00 2001 From: Lukasz Kasprzak Date: Sat, 22 Aug 2026 22:40:07 +0200 Subject: feat(ef): RG 111(a), the sung-Mass commemoration cap Item 1 of Phase 3 (celebrant-rubrics-phase1): the "at Low Mass" commemoration-placement rule the design spec recorded as unread. It is not a new rule -- it is the sung/low axis of RG 111, which colitur already implements. RG 111(a) (LT.txt, "Ratio admittendi commemorationes"): a liturgical day of the first class, AND any non-conventual sung Mass regardless of the day's own class, admits at most one commemoration, and only if it is privileged. (b)/(c)/(d), the same rubric's remaining clauses, give the wider caps colitur's admit already computes -- which is exactly the LOW MASS answer. Exposed as Precedence.sung_mass_commemorations, a pure derivation over the existing Low-Mass admitted list (filter to Privileged, keep the first), not a new stored field on Liturgical_day.t: the input list is already validated and privilege-tagged, so a second field would only create a second place for the same fact to drift out of sync with the first, with no new information gained. Liturgical_day.t.commemorations is now documented as the Low Mass set explicitly, removing the ambiguity its .mli previously left unstated. Tested against synthetic Low-Mass sets (none/one/two privileged, already-first, empty) and two real calendar days resolved through the normal Cal.day pipeline: 2026-08-14 (Vigil of the Assumption, an ordinary-only commemoration, dropped at Sung Mass) and 2026-04-25 (the Major Litanies, RG 80/109(f), privileged, kept at both Masses). --- test/test_rubrics_ef.ml | 38 +++++++++++++++++++++++++++++++++++++- 1 file changed, 37 insertions(+), 1 deletion(-) (limited to 'test/test_rubrics_ef.ml') diff --git a/test/test_rubrics_ef.ml b/test/test_rubrics_ef.ml index 6679702..d533670 100644 --- a/test/test_rubrics_ef.ml +++ b/test/test_rubrics_ef.ml @@ -746,6 +746,38 @@ let test_exhaustive_gloria_domain_sweep () = Alcotest.(check bool) "the full domain reached a real number of Requiem days" true (black > 1_000) end +(* ---- ITEM 1: RG 111(a), the sung-Mass commemoration cap + ({!Colitur_kernel.Precedence.sung_mass_commemorations}) -- two real + calendar days, one of each shape, resolved through the identical + [Cal.day] pipeline every other test in this file uses.
