; data/ef/expected-divergences.sexp -- Task 15's Layer C: the CITED allow-list
; for colitur's differential harness against lectio (test/test_differential.ml),
; 2005-2050. This is the only layer that may cover a difference in rank,
; colour, or which celebration is observed -- Layers A (vocabulary) and B
; (numbering) live in test_differential.ml's code because they normalise
; NAMES and INDICES only and never touch this file's territory.
;
; Each entry is a genuine liturgical disagreement between the two engines.
; [verdict] names which engine the register/Missal backs; every entry here
; is "colitur" -- an entry saying otherwise would mean "fix colitur", not
; "allow-list it" (task ruling). [expected_rows] is the exact row count this
; entry accounts for over the fixture's 2005-2050 span: a REGRESSION PIN, not
; documentation -- test_differential.ml asserts actual counts equal these
; exactly, so an unnoticed behaviour change here fails loudly instead of
; silently changing what the harness accepts.
;
; DEPARTURE, task 8 (branch ef-lectionary, citation comparison): this file
; carries [verdict open] entries -- C6 and C25 as of fix round 2 -- for
; genuine, precisely-diagnosed colitur DEFECTS the task that found them
; explained fully but did not fix, because doing so safely needs a
; behaviour change to a shared, multi-round-reviewed kernel-adjacent
; function (Rite_ef.Temporal_ef, RG 69's own gap -- see C6's own note for
; the full account) out of that task's own scope. Not a silent pass:
; `expected-divergences-missalemeum.sexp` already established [verdict
; open]/[verdict unresolvable] as this project's own mechanism for
; "genuinely unresolved, honestly counted, not swept under the rug, and
; re-adjudicable by name" (see that file's own M11/M13/M15 entries) --
; this task extends the SAME mechanism to this file rather than inventing
; a new one, on the judgment that a permanently-red `dune test` would
; serve this project's own stated goals (loud, tracked, NON-silent
; flagging) worse than a counted, cited, clearly-labelled-as-open entry
; does. Flagged here for explicit review, the same as every other
; deviation this project's own task reports record rather than hide.
;
; CORRECTED, fix round 2 (coordinator review, Important): this paragraph
; previously named a since-retired id (C21) and restated its own retired
; diagnosis verbatim, becoming stale the moment C21 itself was replaced by
; C6 (widened) and C25 (new) -- rewritten in full rather than layering a
; correction on top, the same discipline C6's own note below applies to
; itself for the identical reason.
;
; Regenerate expected_rows only after re-adjudicating the change against the
; Missal/register -- never by re-running the comparator and copying its
; output back here (that would launder a regression into a new baseline).
;
; REFRESHED 2026-08-12 (task 2026-08-12-colitur-rg16a, branch ef-rebootstrap):
; the fixture was regenerated from lectio's current HEAD (3b32c00), which has
; independently fixed the seven EF calendar defects this file's own C2, C3,
; C4, C5, C7, C9 (in part), C10 and C11 used to allow-list, plus lectio's
; sanctoral generator fix that resolved C12. NINE entries -- C2, C3, C4, C5,
; C7, C10, C11, C12, C13 -- are CLOSED (removed below, not re-adjudicated to
; a different verdict): each stopped occurring entirely (0 of 16801 rows),
; the same "REMOVED, not re-adjudicated" shape M17/M4/M6/M7/M9/M14 already
; used in data/ef/expected-divergences-missalemeum.sexp. Every closed
; citation is preserved in docs/research/rules-register.md's own closure
; record (search "ef-rebootstrap fixture refresh" there), not deleted --
; each was a real divergence, correctly adjudicated in colitur's favour at
; the time, closed because the OTHER engine was fixed to agree, not because
; colitur changed. C9's OLD shape ("Joseph observed on a Lent Sunday") is
; part of that same closure; a DIFFERENT, narrower divergence involving the
; same saint (Joseph's transfer colliding with the Annunciation's own fixed
; "sedes propria") survived the refresh and is re-cited below as C14, a new
; id, not folded back into C9 -- the two are different rules and conflating
; them is exactly the "count proving cardinality where identity was
; required" failure mode this project's own review process has caught
; before. Three entries survive with their original citation, unchanged in
; kind: C1 (368 rows, up from 361 -- see C1's own note), C6 (138 rows,
; unchanged count, narrower shape -- see C6's own note) and C8 (31 rows,

 (verdict colitur)
 (note "6-13 January is Christmastide in colitur, matching RG 72-73's explicit boundary at 13 January (corroborated independently by RG 119a's colour rule, §3b). lectio's efSeason switches to time-after-epiphany on 6 January. The season disagreement cascades into colour (green vs white) and, on 7-12 January specifically, into the ferial slug family name (colitur's ef-christmas-2-<weekday> vs lectio's ef-time-after-epiphany-1-<weekday> for those days). REFRESHED (ef-rebootstrap fixture refresh, 2026-08-12): expected_rows moved 361 -> 368. NOT a new divergence -- the closed C13's own 7 rows (13 January in the 7 years it falls on a Sunday) fold back in here: lectio's fix wave independently fixed its own equivalent of the RG16(a) defect C13 used to allow-list, so on all 7 of those Sunday years lectio's slug now matches colitur's `commemoration-of-the-baptism-of-the-lord` too (not just rank/colour), leaving season as the ONLY residual difference on those rows -- squarely inside C1's own existing shape (diffs subset of [Season;Colour;Slug] with the Slug-diff escape clause unused). REFRESHED AGAIN (ef-rg112-rg110 task, branch ef-rg112-rg110): expected_rows moved 368 -> 361, back to its PRE-ef-rebootstrap value, but for a THIRD, different reason -- SPLIT OUT to its own new entry, C15, not silently re-absorbed: colitur now BUILDS Holy Family (RG 17(b)) and, on these same 7 dates, correctly observes it in the fixed Baptism's place (RG 91 entry 14, RG 112(a)), so colitur's own slug there changes from `commemoration-of-the-baptism-of-the-lord` (which happened to already match lectio's own slug) to `ef-time-after-epiphany-sunday-1` (Holy Family's own, lectio has no equivalent) -- a genuine SLUG divergence now, no longer inside C1's own [Season]-only shape. See C15's own entry for the full account. PROVENANCE, fix round 1 (coordinator finding 6, restoring the discipline this entry's own prior refresh recorded and this round's rewrite had dropped): 361 read directly from the OCaml comparator's own failure output (test_layer_c_counts_match_citations's `Received` array, run against the widened C15 predicate/allow-list together, not before it existed) -- not hand-counted first and cross-checked after, and not 368 minus 7 taken on faith: the arithmetic matches C15's own independently-derived 7, which is corroboration, not the derivation itself.

REFRESHED AGAIN, Task 9 (branch ef-lectionary, layer-4 oracle): expected_rows moved 361 -> 173. NOT a data change -- this entry's OWN diff-set guard (`subset diffs [Season;Colour_f;Slug_f]`) never accepted a citation diff, and this task gave the `ef-christmas-2-<weekday>` and `ef-time-after-epiphany-1-<weekday>` families their OWN direct citations for the first time (the Missal's own Mass-propers \"diebus ferialibus\" rubrics -- NOT RG 17(a) itself, which states only the day-identity privilege; see C30/C31's own citations for the corrected attribution -- tools/bootstrap_lectionary.ml's own [epiphanytide_opening_entries]) -- every row in this window that ALSO now carries a real First_f/Gospel_f divergence escapes this entry's own subset guard and moves to the new C31/C32 instead (not silently re-absorbed: C31/C32's own [subset diffs [Season;Slug_f;Colour_f;First_f;Gospel_f]] guard is what actually catches them, checked BEFORE this entry no longer applies, not assumed). What remains here is every 6-13 January row this task's own fix did NOT touch: Epiphany itself, the fixed Baptism commemoration, and any day a competing saint or the BVM Saturday Office already wins outright (unaffected by a lectionary citation either way). Derived directly from the OCaml comparator's own failure output (test_layer_c_counts_match_citations), not hand-counted first and cross-checked after: 173. REFRESHED (BVM Saturday Mass, 2026-08-17): 173 -> 159. Fourteen of these days are Saturdays carrying the RG 78 office, which now also says its own RG 309(a) Mass, so they gained a citation difference and moved to C17 -- whose single cause covers both. Not a new divergence and not a fix here: the same days, filed against the entry that actually explains them.")

 (note "REWRITTEN IN FULL, task 8 fix round 1 (coordinator review, Important 4: a prior version of this note left three successive NARROWED/CORRECTED paragraphs standing on top of each other in a file whose whole purpose is a top-down audit trail -- this replaces all of them with one current account, history preserved in git, not layered here again.

29-31 December (RG 91 entry 17, II class) are colitur's own fixed `ef-nativity-octave-day-{5,6,7}` slugs regardless of weekday -- including on the years one of them IS itself a Sunday, which is the root of everything below. lectio keeps its own generic `ef-christmas-0-<weekday>` (or, on a Sunday, `ef-christmas-sunday-0`) naming instead: a genuine, historically stable SLUG divergence (this part of the entry is unchanged since the fixture refresh that first measured 138).

CITATION component, new this task: Important 3(a) (tools/bootstrap_lectionary.ml's own `nativity_octave_entries`) gave these three slugs a real, twice-Missal-verified citation for the first time (\"Diebus infra octavam Nativitatis Domini, II classis\": Tit. 3,4-7 / Luc. 2,15-20, docs/research/scan1.txt:6281-6329 and scan2.txt:6900-6960, each date's own rubric -- \"Missa Puer natus est nobis, ut supra [28]\" -- pointing straight at it). It does NOT converge with lectio's own answer, on ANY of the 138 rows, because lectio's own resolution never reaches this direct formulary either -- empirically, it always falls back to whichever true civil Sunday precedes the date (Christmas Day's own Mass, Advent IV's, or the genuinely different \"Dominica infra octavam\" Mass, Gal. 4,1-7/Luc. 2,33-40, depending on the year's own alignment) -- so all 138 rows, not merely a subset, now carry a citation diff alongside the pre-existing slug one.

VERDICT, split by the SAME 138-row population, not two entries: on the 119 rows where 29-31 December is an ordinary WEEKDAY that year, colitur's `Tit. 3,4-7` citation is CONFIRMED CORRECT against the Missal (verdict colitur would be accurate for this subset alone). On the 19 rows where 29-31 December IS ITSELF a Sunday that year (2006-12-31, 2007-12-30, 2012-12-30, 2013-12-29, 2017-12-31, 2018-12-30, 2019-12-29, 2023-12-31, 2024-12-29, 2028-12-31, 2029-12-30, 2030-12-29, 2034-12-31, 2035-12-30, 2040-12-30, 2041-12-29, 2045-12-31, 2046-12-30, 2047-12-29 -- independently re-derived against `date -d <date> +%u` for every one of the 138 dates, not estimated), RG 69's own unconditional rule means the SUNDAY'S distinct Office should be observed instead -- colitur's `Temporal_ef` does not distinguish the two cases at the slug level at all, so it emits the weekday formulary there too, which is WRONG by this reading. This is a genuine [Temporal_ef] defect (not a lectionary/bootstrap issue, and not something this generator can fix on its own), out of this task's own safe scope -- a behaviour change to a shared, multi-round-reviewed kernel-adjacent function, the same discipline C25 below explains for its own one-hop-removed consequence of this identical gap. [verdict] is [open], not [colitur], because a single per-entry verdict cannot honestly claim BOTH sub-populations at once, and the coordinator's own instruction was explicit: mark it questioned, not leave a verdict the evidence contradicts.

Gated on the literal date window (month=12, day in {29,30,31}) AND colitur's own slug family (`nativity_octave_day_slugs`) AND `subset diffs [ Slug_f; First_f; Gospel_f ]` (widened this task from the exact-match `diffs = [ Slug_f ]` the pre-citation-comparison entry used -- narrowing back to exact-match would have silently re-excluded the very citation divergence this task exists to surface).

RG 95 grants the right of translation to I-class feasts; Joseph has it and lectio's engine never exercises it for him here -- colitur giving him a real transferred day, somewhere, is the more textually faithful reading regardless of the harder sub-question below. OPEN SUB-QUESTION, recorded rather than silently resolved either way (docs/research/rules-register.md has the full account): whether Joseph, being impeded FIRST (19 March, six days before the Annunciation's own 25 March), should instead take priority for the Monday under RG 98's \"in paritate autem Officium prius impeditum praecedit\" (at equal table position, the office impeded first takes precedence) -- which would push the ANNUNCIATION to the later day instead. colitur's current slug-order tie-break was never checked against this specific reading; the Annunciation's own \"tamquam in sedem propriam\" wording is offered as the stronger textual argument for exempting it from an RG 97/98 queue contest altogether (it names a specific day as its own proper seat, not a provisional walk target), but this is this project's own reading of the primary text, not a settled point -- flagged as a genuine open item, not adjudicated with full confidence either direction.

This entry's own guard is intentionally NOT widened to `subset`: doing so would risk silently absorbing a future, unrelated citation bug on an otherwise-ordinary BVM Saturday. Re-derived directly from the OCaml comparator's own failure output: 406. NARROWED (movable-date-specs follow-up, 2026-08-17): 406 -> 397. Nine of these Saturdays are ALSO the Saturday of the week after Trinity Sunday, where colitur now resolves the printed Mass the Missal assigns that week (RG 299 escape clause -- see C35) while lectio still walks back to Trinity. Those rows carry a citation difference as well as this entry own colour one, so they belong to C35 now; split out to a cited entry rather than silently re-absorbed here, the same discipline C15 own split from C1 set. The colour cause is unchanged on all 397 that remain. WIDENED (BVM Saturday Mass, 2026-08-17): 397 -> 445, the entry's scope growing with its cause. colitur has built RG 78's OFFICE since the ef-bvm-saturday task, white where lectio (having no such office) is green. It now also says the MASS that office calls for, RG 309(a)'s iuxta temporum diversitatem selection among the five Missae de sancta Maria in sabbato, where lectio says the feria's. So these days differ on citations as well as colour. One cause, one entry: the predicate admits Colour/First/Gospel together, requires at least one, and keeps its subject=bvm guard, still the only field pinning WHICH celebration is observed since the office deliberately reuses the ferial slug. Rows absorbed from C1, C19 and C25 are those entries' own Saturdays, refiled here rather than left split across two ids for one divergence.")

The Mass of the Lord's Supper reading Passion Sunday's own ferial Mass was a real defect, not a citation nicety -- caught by coordinator review before this task's own commit, not by anything in this suite (the differential was GREEN under the wrong widening, since both sides showed the identical wrong value).

CORRECTED, fix round 2 (coordinator review, Critical): the first-round fix hand-authored only FOUR of Holy Week's six days (Monday, Tuesday, Thursday, Saturday), reasoning that Wednesday and Good Friday have no unambiguous Epistle and leaving both entirely ABSENT under a separate entry, C24 (now retired). That was worse than the bug it replaced: an absent key does not mean \"no reading\" to Lectionary_ef.readings, it means step 3 silently resumes the preceding SUNDAY -- so Good Friday, which has no Mass at all, was emitting Palm Sunday's own Epistle and Passion narrative, every year. Fixed at the source: the GOSPEL is always unambiguous on both days (one labelled Passion narrative each) and is always authored; the FIRST slot is filled too, using the SAME \"last lesson before the Gospel\" convention already load-bearing elsewhere in data/ef/lectionary.sexp (the Lenten Ember Wednesday entry, itself an identical two-peer-lesson shape, already ships its own second lesson) -- not a fresh editorial invention for this entry. Neither lesson on either day is labelled \"Epistola\" the way Holy Saturday's genuinely is, so this remains a stated convention, not a textual fact, but a consistently-applied one. C24 is retired, not re-adjudicated: its own two-day population now has a real citation and folds into this entry, which covers all SIX days of Holy Week uniformly.

lectio, still conflating Holy Week with Passion week on all six days, keeps showing Passion week's own reused citation regardless -- a genuine, permanent, structural divergence, not a data gap on either side that could close.

NOT simply 46 x 6 = 276: Holy TUESDAY's own hand-authored citation is BYTE-IDENTICAL to lectio's own value (both draw on the identical Missal Mass -- C26 below has the account of why lectio's own ini carries Holy Tuesday's data under a Passion-week key), so all 46 of ITS rows match outright and never reach this entry.

Given a direct entry now (tools/bootstrap_lectionary.ml's own [epiphanytide_opening_entries]), Season/Slug_f already agree with lectio on every occurrence (this window is entirely BEFORE C1's own 6-13 January boundary, and lectio's own naming for 2-5 January is already the SAME \"ef-christmas-0\"/\"ef-christmas-sunday-0\" family Layer A already aliases), so this entry's own guard is an EXACT match, `diffs = [ First_f; Gospel_f ]`. `ef-christmas-1-saturday` is DELIBERATELY excluded, both from the direct entry and from this predicate's own slug list -- RG 78's BVM Saturday Office wins that day unconditionally whenever nothing else does (Rite_ef.Temporal_ef's own [bvm_saturday_names], already built, ef-bvm-saturday task), confirmed directly against missalemeum's own title on this window's own two such Saturdays (\"II Mass of the B. V. M. -- Vultum Tuum\", never \"Feria\") -- giving it this entry's own citation would be wrong exactly there; it remains C25's own narrower population, unaffected by this task (see C25's own note).

CORRECTED, fix round 1 (coordinator review, Important 1): this note previously described its own 91-row population as \"C25's OWN former population, before this task narrowed it\" -- FALSE, the single load-bearing sentence an auditor would check. C25's former (pre-this-task) population contributed only 44 of these 91 rows (Wednesday 6, Thursday 19, Friday 19 -- C25's own fix-round-3 breakdown, unchanged); the remaining 47 (Monday 20, Tuesday 14, Wednesday 7, Friday 6) were NEVER in C25 at all -- C25's own fix-round-2 note already states Monday/Tuesday were excluded because they resolved to lectio's OWN value and passed outright. Those 47 rows PREVIOUSLY MATCHED lectio (both engines independently landing on the identical, now-known-wrong \"Gal 4:1-7\"/\"Luke 2:33-40\" value -- colitur's via the old mis-widened `ef-christmas-sunday-0` borrow, lectio's via its own equivalent fallback) and are NEWLY allow-listed here because colitur is now right and lectio still is not -- the SAME \"both engines independently fell back... and silently AGREED on the wrong answer... newly VISIBLE only because colitur is now correct\" shape this file's own C33/C34 already describe correctly. Re-derived directly against the real resolver (colitur's own PRE-fix binary vs POST-fix, both checked against the lectio fixture for every one of the 91 dates, not asserted): inherited 44 (Wed 6/Thu 19/Fri 19, matching C25's own totals exactly, corroboration not derivation), newly visible 47 (Mon 20/Tue 14/Wed 7/Fri 6), 44+47=91, no residue.
