From 3583448631c1f1cf0767728d605a858fcb810cfc Mon Sep 17 00:00:00 2001 From: Lukasz Kasprzak Date: Tue, 11 Aug 2026 23:41:33 +0200 Subject: rite(ef): an impeded I-class Sunday commemorates, not transfers disposition's Class1 branch was unconditional on rank, so an impeded I-class Sunday (Advent/Lent/Passiontide/Low Sunday) currently transferred like a feast. RG 95 (register lines 323, 363) restricts the right of translation to I-class FEASTS -- RG 91's own table lists Sundays as a separate row (entry 6, line 332) from feasts (entries 11-13, lines 337-339) -- and RG 109(a) (line 374) lists "of a Sunday" as a privileged commemoration category, which presupposes an impeded Sunday stays put rather than moving to another day. Excludes is_sunday_slug losers from the Transfer branch so they fall through to the existing Commemorate (privilege_of loser) branch, which already tags them Privileged via RG 109(a) with no further change. Fires on real dates in the 2005-2050 differential window: 24 December on Advent IV in 2023, 2028, 2034, 2045; 8 December on an Advent Sunday in 2024, 2030, 2041. Verified no previously-passing Transfer assertion used a Sunday-shaped loser (grepped test_precedence_ef.ml, test_calendar.ml -- which uses its own synthetic rite unrelated to Precedence_ef.disposition -- test_colitur.ml, test_validate.ml); confirmed by mutation-reverting the fix and observing exactly the one new test fail, nothing else. --- test/test_precedence_ef.ml | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'test/test_precedence_ef.ml') diff --git a/test/test_precedence_ef.ml b/test/test_precedence_ef.ml index f3fd357..09c41fd 100644 --- a/test/test_precedence_ef.ml +++ b/test/test_precedence_ef.ml @@ -318,6 +318,28 @@ let disposition_cases = cand "ef-nativity", cand ~origin:P.Sanctoral ~layer:PE.universal_layer "ef-local-i-class-feast", "Transfer" ); + (* Fix round 1 (post-Task-9 review): RG 95 (register lines 323, 363) + restricts the right of translation to I-class FEASTS -- RG 91's own + table lists Sundays as a separate row (entry 6, register line 332) + from feasts (entries 11-13, lines 337-339) -- so an impeded I-class + Sunday must NOT transfer, unlike the plain I-class feast row above: + same [Class1] rank, same kind of winner, the ONLY difference is that + this loser's slug carries [PE.sunday_marker].
