; data/of/expected-divergences-litcal.sexp -- of-litcal-layer task
; (2026-08-25)'s cited allow-list for the litcal external-validation layer
; (test/test_litcal_of.ml), fixture window 2023-12-03..2035-12-01 (twelve
; litcal liturgical years, 4382 civil days).
;
; ONE active entry. The Ordinary Time WEEK comparison (the actual risk this
; layer exists to validate, Normae n. 44's two-block resumption arithmetic)
; carries NO allow-list at all -- see test_litcal_of.ml's own
; [test_ordinary_time_week_matches] comment for why a witnessed week is
; zero-tolerance, not an "expected divergence" shape.

; L1 -- OPEN BY DESIGN, adjudicated "colitur" (a deliberate, cited design
; decision, not a defect on either side). Fires on every litcal row tagged
; EASTER_TRIDUUM: Holy Thursday's own evening Mass of the Lord's Supper,
; Good Friday, and Holy Saturday, across all twelve fixture years -- 3
; dates x 12 years = 36 rows, exactly.
;
; litcal's own data model gives the Sacred Triduum a season value of its
; own (`liturgical_season: EASTER_TRIDUUM`), distinct from both LENT and
; EASTER. colitur's `Vocab_of.season` has no such value: it keeps the
; whole civil day of Holy Thursday, Good Friday and Holy Saturday inside
; `Lent`, per lib/rites/rite_of/temporal_of.ml's own top-of-module
; citation --
;
;   Normae n. 28 (PRIMARY): "Tempus Quadragesimae decurrit a feria IV
;   Cinerum ad Missam in Cena Domini EXCLUSIVE" -- Lent runs from Ash
;   Wednesday up to (excluding) the evening Mass of the Lord's Supper. At
;   colitur's own civil-day granularity (one season per date, never a
;   sub-day boundary), the excluded boundary is an EVENT within Holy
;   Thursday's own civil day, not an earlier day -- so the whole day stays
;   Lent.
;
;   Normae n. 30 (PRIMARY, independent second anchor): "Dominicae huius
;   temporis appellantur dominicae I, II, III, IV, V in Quadragesima.
;   Dominica sexta, in qua initium sumit Hebdomada sancta, dicitur...
;   'Dominica in palmis de Passione Domini'" -- Holy Week (Palm Sunday
;   through the Vigil) is Lent's OWN sixth week by the Missal's own prose,
;   not a season outside Lent's numbering.
;
;   Normae Titulus II's own six subsection headings (II-VI): FIVE are
;   literally called a "tempus"; "Triduum paschale" is deliberately NOT --
;   a real textual signal that the document's own authors did not count
;   the Triduum among the season vocabulary a day's season field needs to
;   name, corroborated by the Missal's own Mass-propers structure printing
;   "HEBDOMADA SANCTA" and "SACRUM TRIDUUM PASCHALE" as two separate
;   headings, neither titled "tempus" either.
;
; So litcal's EASTER_TRIDUUM is a genuine, defensible IMPLEMENTATION
; choice (giving the Triduum its own practical season tag, useful for an
; API consumer), and colitur's `Lent` is an equally genuine, primary-
; source-argued READING of the same Normae text that declines to invent a
; sixth season value the text itself does not name. Neither side is wrong;
; this is a vocabulary question the two engines answer differently by
; design, not a computation either got wrong -- verdict "colitur" here
; means "colitur's own choice is deliberate and cited", not "litcal is in
; error".
;
; The ROW SELECTION that produces exactly 36, not 24 or 48, is explained
; in test/fixtures/litcal-temporal-2024-2035.sexp's own header and
; tools/extract_litcal_ordo.py's own top-of-file comment: Holy Thursday
; carries TWO non-vigil litcal rows on the same civil date (the Chrism
; Mass, LENT, and the evening Mass of the Lord's Supper, EASTER_TRIDUUM);
; the Chrism row is excluded upstream (in the fixture generator, not
; here) so the evening Mass -- the day's own actual public/parish liturgy
; -- represents the date, giving Holy Thursday the SAME season shape as
; Good Friday and Holy Saturday (each of which has only one non-vigil row,
; always EASTER_TRIDUUM) rather than an inconsistent 2-of-3 split.

; L2, L3 -- CLOSED, REMOVED (W2 fix, CLAUDE.md, temporal_of.ml). These two
; entries used to record a defect from task 6 (2026-08-26): the litcal layer
; extended beyond season/week to GRADE and IDENTITY, and both fired on the
; SAME date, the SAME then-known, then-PINNED-NOT-FIXED gap test_rite_of.ml
; used to record: Normae n. 35(a)'s "Dominica infra octavam Nativitatis, vel,
; ea deficiente, die 30 decembris" fallback was never reached by
; {!Rite_of.Temporal_of.temporal} in a year 25 December is itself a Sunday
; (its Holy-Family test lived inside the Sunday-only dispatch arm of
; [sunday_slug], so the 30-December fallback [holy_family] itself computed
; correctly was never actually consulted there). 2033 was this fixture's own
; live witness. {!Rite_of.Temporal_of.temporal} now consults
; {!Rite_of.Temporal_of.holy_family} directly, independent of weekday, so
; litcal and colitur agree on 30 December 2033 on both axes -- test_litcal_of
; .ml's own [test_no_holy_family_2033_divergence] asserts this directly.
; `expected_rows` for both would now be 0 (no divergent rows remain), so the
; entries are removed rather than kept as zero-value ghosts, the same
; "CLOSED, REMOVED" discipline data/ef/expected-divergences-missalemeum.sexp
; already follows for a closed entry.

; L4 -- litcal's own [grade_lcl] text "celebration with precedence over
; solemnities" (this fixture's own display word for Tabula I.1/I.2) is ALSO
; used for Trinity Sunday and Corpus Christi, every one of the fixture's 12
; years (24 rows). precedence_of.ml's own Tabula I.2 transcription --
; "Nativitas Domini, Epiphania, Ascensio et Pentecostes; dominicae Adventus,
; Quadragesimae et Paschae; feria IV Cinerum; hebdomada sancta a feria II ad
; V" -- names neither: both are "Sollemnitates Domini", Tabula I.3 (band
; 30), the SAME entry {!Rite_of.Precedence_of.band} gives ChristKing, a
; structurally identical "Solemnity of the Lord anchored to a Sunday within
; Ordinary Time" -- and litcal ITSELF labels ChristKing "SOLEMNITY", not
; this text, offered as corroborating (not conclusive -- this task did not
; inspect litcal's own source) evidence that litcal's own grade vocabulary
; is coarser/inconsistent here, not a considered different Tabula reading.
((id L4)

 (expected_rows 24))

; L5 -- litcal's own data is STALE. St Mary Magdalene (22 July) reads grade
; "Memorial" on every one of the 10 years this fixture witnesses her (2 of
; the 12 years: an ordinary per-annum Sunday there instead, on both sides,
; not a witness). The Congregation for Divine Worship's decree "Sanctae
; Mariae Magdalenae" (3 June 2016, Prot. n. 708/2015, AAS 108 (2016)
; 798-799) raised her to FEAST -- colitur's data/of/amendments/
; 005-mary-magdalene-rank.sexp applies it (band 70); litcal's grade text
; shows no sign of having done so.

; L6, L7 -- a genuine, UNADJUDICATED tie-break, found live, not anticipated.
; Easter 2033 is 17 April, putting the movable Solemnity of the Sacred
; Heart (Easter+68) on 24 June, the SAME fixed date as the Nativity of St
; John the Baptist -- an exact Tabula I.3/band-30 tie.
; Colitur_kernel.Precedence.resolve's own tie-break (precedence.ml's
; [compare_by], Slug.compare when bands are equal) hands the day to
; "birth-of-saint-john-the-baptist" alphabetically, and
; Rite_of.Precedence_of.disposition Transfers the loser (Sacred Heart) to
; 25 June. litcal's own answer is the OPPOSITE: Sacred Heart keeps 24 June,
; and John the Baptist is shown a day EARLY, on 23 June. NEITHER answer is
; dictated by any citation this task found -- the Tabula ranks both
; candidates at the identical entry, and nothing in the Normae or IGMR
; extracts a Lord-outranks-Saint rule WITHIN one Tabula entry the way, e.g.,
; RG 112(a) does on the EF side for a narrower case. NOT fixed here (a

; L8, L9 -- a SECOND, newly-found instance of precedence_of.mli's own
; documented "KNOWN UNIMPLEMENTED FOURTH RULE" (Normae n. 60's own "ad
; proximiorem diem" -- the nearest day, not necessarily the nearest
; FOLLOWING one -- constrained to forward-only search by
; Colitur_kernel.Rite.t.transfer_target's own strictly-later contract).
; That section's own worked example is St Joseph falling exactly ON Palm
; Sunday (Normae n. 56(f), anticipated to 18 March); this is a DIFFERENT
; date shape reaching the SAME underlying limitation. Easter 2035 is 25
; March, putting St Joseph's fixed 19 March on the MONDAY of Holy Week
; (Easter-6, a privileged Tabula I.2 feria, not a Sunday) -- Normae n. 5's
; own "following Monday" rule (keyed to a privileged SUNDAY) does not apply
; here at all, so this falls to n. 60's general rule 3, forward-only on
; colitur's side, landing Joseph on 3 April (Easter+9). litcal's own answer
; anticipates BACKWARD instead, to 17 March -- the Saturday immediately
; before Palm Sunday, a generalisation of n. 56(f)'s own underlying
