; data/of/amendments/010-narek-avila-hildegard.sexp -- ADDS three Doctors
; of the Church to the General Roman Calendar: St Gregory of Narek, St
; John of Avila, St Hildegard of Bingen. ONE decree, three entries --
; docs/research/of/PROVENANCE-amendments.md's own items 10-12.
;
; Decree: Congregation for Divine Worship and the Discipline of the
; Sacraments, 25 January 2021, Prot. N. 40/21. Signed Robertus Card. Sarah
; (Praefectus) + Arturus Roche (Archiepiscopus a Secretis).
; Published: AAS 113 (2021), 225-226.
;
; What it does: inscribes three memoria-ad-libitum entries -- 27 February
; (Narek), 10 May (Avila), 17 September (Hildegard). All three were
; declared Doctors of the Church years earlier (Avila/Hildegard 7 October
; 2012, Narek 21 February 2015); the GRC inscription followed 6-9 years
; later. Verified directly against the decree's own calendarium table
; rows (docs/research/of/aas-monthly/2021_febbraio.pdf):
;   line 2170: "27 S. Gregorii Narecensis, abbatis et Ecclesiae doctoris"
;   line 2300: "10 S. Ioannis De Avila, presbyteri et Ecclesiae doctoris"
;   line 2432: "17 S. Hildegardis Bingensis, virginis et Ecclesiae
;               doctoris"
;
; No lectio entries exist for this decree; `en`/`la` are this task's own
; rendering, `la` matching the calendarium rows above verbatim.
;
; *** FINDING: 17 September already carries a universal entry ***
; (calendar-2002.sexp's own "robert-bellarmine-bishop-and-doctor",
; Memoria_ad_libitum, White) -- verified: `grep '(month 9) (day 17)'`
; finds exactly those two blocks once this file is applied. Both are
; ordinary optional memorials, so Normae universales n. 14's own text
; ("Si eodem die plures inscribuntur in calendario memoriae ad libitum,
; una tantum celebrari potest, omissis ceteris" -- if several optional
; memorials are inscribed on the same day, only one may be celebrated,
; the rest omitted) governs correctly and is NOT a defect. But
; Precedence_of's tie-break for two same-band candidates is
; Slug.compare, and "hildegard-of-bingen-virgin-and-doctor" sorts BEFORE
; "robert-bellarmine-bishop-and-doctor" -- so applying this overlay
; changes which candidate `Precedence.resolve` reports as OBSERVED on
; every 17 September, from Robert Bellarmine to Hildegard. Both are
; legitimate choices under n. 14 (the celebrant elects either), but
; colitur's single-observed-day model cannot express "elective": it
; reports one deterministically, and this file changes which one. Not a
; new architectural gap -- 9 October already carries two ad-libitum
; entries in the shipped 2002 base (Denis & companions, John Leonardi)
; with the identical shape, undisturbed here (see
; 013-john-henry-newman.sexp's own note: adding a third candidate there
; leaves Denis, already alphabetically first, unchanged as observed).
