Mary, Mother of the Church (Easter+50) and the Immaculate Heart of Mary
(Easter+69) are both movable obligatory memorials that can land on a
FIXED obligatory memorial's own date -- e.g. 2011-06-13 and 2015-06-13,
both against Anthony of Padua. Both candidates banded identically at
Tabula III.10 (100, both universal Memoria_obligatoria), a tie band
could not break, so Precedence.resolve's kernel-level alphabetical
Slug.compare tie-break silently picked instead -- 892 days for Mater
Ecclesiae and 1109 for the Immaculate Heart across 1583-9999, all one
shape (measured against the pre-fix alphabetical order directly, zero
unexplained).
Searched the corpus rather than inventing a rule. colitur's two
previously-checked primary sources really are silent: the 2018 decree
(AAS 110, 437-438) never addresses universal-calendar coincidence, and
Normae n. 14's third clause resolves only two AD-LIBITUM memorials
colliding. A third source resolves it: the CDWDS's own "Notification on
the Memorial of the Blessed Virgin Mary, Mother of the Church" (24 March
2018 -- same dicastery and signatories as the decree; published only on
vatican.va, confirmed absent from the AAS 2018 combined index) states
that when this memorial "coincides with another Memorial of a Saint or
Blessed... the Memorial of the Blessed Virgin Mary is to prevail," and
extends the identical reasoning to the Immaculate Heart of Mary by name.
This is a rubric, not colitur's own reasoned choice.
Implemented as a sub-rank of 95, strictly between Tabula entries 9 and
10 -- the same "fits between neighbours" technique this module already
uses elsewhere -- scoped to the two named slugs rather than
[subject = Bvm], since the Notification's own reasoning is specifically
about a memorial's link to a movable solemnity of the Lord, not a
blanket Marian precedence.
Golden pin updated: test_rite_of.ml's 2011-06-13 tie now pins Mary,
Mother of the Church as observed (was Anthony of Padua, labelled "known
arbitrary"), with the header rewritten to state the outcome now rests on
the Notification, not a coin-flip. The litcal oracle allow-list gains
L10: litcal's own grade vocabulary has no representation for a 95
sub-rank (everything Memoria_obligatoria reads "Memorial"), a
representational gap in litcal, not a computational disagreement -- the
identity axis is untouched and needed no new entry.

Parse.verse_range's [last] endpoint gains an optional chapter
(Parse.verse_end: { chapter : int option; verse : verse_num }), so a
hyphen range whose two endpoints lie in different chapters
("1 John 1:5-2:2") can be represented at all. Rejected: a bare
[int option] living alongside [last] as a second field on
verse_range -- that would let 'a chapter with no verse' exist as a
constructible value.
parse_part now splits a part's leading "chapter:" at the FIRST
colon only (not every colon), so the verses side can itself carry a
second colon from a crossing range. parse_range detects a crossing
by checking whether the range's right-hand side contains ':', and
skips the same-chapter descending-range guard for that case (a later
chapter is always "ahead", whatever its own verse numbers are).
Handles the compound shape too -- a crossing range followed by
further, same-chapter verse references in the same comma list
("Matthew 9:35-10:1,5a,6-8") -- since those trailing pieces parse as
ordinary bare verses/ranges, unaffected by the preceding crossing.
Render's one_range renders a crossing [last] through the same
chapter_verse template one_part already uses for the part's own
leading "chapter:verses", so a style that reconfigures the
chapter/verse separator renders a crossing endpoint in that same
convention rather than a hardcoded ':'.
This closes the W4 known-wrong: 41 (now 49, after an intervening
Second-reading extraction) of the OF lectionary's citations printed
unconverted, every one this exact shape. test_citation_coverage_of.ml's
pinned residual is now empty and asserted exactly, over the full
1725-field data/of/lectionary.sexp population, including the round-trip
check (parse -> render -> parse structural equality). test_citation.ml
gains direct parse-suite cases for the basic crossing, the compound
shape, a mid-list crossing, a crossing with a sub-verse letter, and a
malformed-crossing rejection.
data/of/lectionary.sexp is regenerated via its own generator
(tools/bootstrap_lectionary_of.ml, whose own embedded header text is
updated to match); only comment lines change, confirmed by diff --
no lectionary entry differs. test_lectionary_of.ml's whole-file
SHA-256 pin is updated to match.
EF is unaffected: data/ef/ is untouched since v1.0.0, and a direct
byte comparison of `colitur day`/`colitur readings` for 2026, 1583
and 9999 against a git-worktree build of 1c0137d is identical on all
six outputs.

temporal_of.ml's temporal only ever reached holy_family's own correct
26-31 December / 30 December fallback logic through sunday_slug, which
returns None immediately for a non-Sunday date. In a year 25 December
is itself a Sunday (26-31 December then holding no Sunday of its own),
the feast vanished entirely and fell through to an ordinary Christmas
ferial slug -- confirmed on 2022, 2033, 2039, 2044, 2050 (and roughly
1583..9999 domain-wide, one year in seven).
temporal's dispatch now consults holy_family directly, independent of
weekday, between the sunday_slug and christmas_feria_slug branches,
carrying the identical identity the Sunday case already builds
(subject Lord, holy_family_names, rank Festum). holy_family and
anchors were already correct and needed no change.
Added a direct example-based test for the fallback across five
affected years plus a control for the unaffected Sunday case, and a
domain-wide property (Holy Family is observed in every liturgical
year 1583-9999) folded into both the 200-sample QCheck run and the
exhaustive sweep -- the property that would have caught this directly.
Un-pinned the now-fixed behaviour everywhere it was recorded as
known-wrong: test_rite_of.ml's own 1583 pin (rewritten to assert the
fix), test_validate_of.ml's own independent exhaustive-sweep counter
and landmark-year filter (found via make check, not the initial
survey), and data/of/expected-divergences-litcal.sexp's L2/L3
allow-list entries against the litcal oracle (closed and removed, with
a dedicated regression test replacing the allow-list's own silence).

I7 (final-review.md, 2026-08-25-colitur-of-phases-3-5): OF Sundays and
solemnities shipped without the Second reading, and the lectionary
data header called the First reading an "Epistle" -- EF vocabulary.
The sole blocker was Validate's own kernel-hardcoded assertion that a
well-formed day's sorted citation parts are exactly [First; Gospel];
Citation.part already carried Second.
Rite.t gains citation_shapes : Citation.part list list, the fourth
EF-shaped kernel misfit (after Preface.t, Mass_formulary.source,
transfer_target's strictly-later contract) and the first fixed rather
than only documented. EF supplies its one shape unchanged; OF supplies
two, [First; Gospel] on a feria/feast/memorial and [First; Second;
Gospel] on a Sunday or solemnity (OLM 1981 Praenotanda n. 66.1 vs
n. 69.1, n. 84(b)/(c), page-image verified against olm-1981.pdf).
Validate's "citations" check now matches against the rite's own
declared shapes rather than a single literal pattern, preserving all
three invariants it always enforced: zero or one complete shape, never
partial; no part outside what the rite declares; no part repeated.
bootstrap_lectionary_of.ml's cite now extracts a Second reading from
Sunday-cycle ini sections only, correctly excluding the one stray
`second` field lectio's snapshot carries on a weekday-cycle section (a
content-verified scraping artifact). The hand-authored Christmas Day
entry gains its own Second reading from the same OLM passage already
cited for its First/Gospel. Regenerated data/of/lectionary.sexp: 771
entries unchanged, citation fields 1542 -> 1725 (+183, all Second
readings), SHA-256 re-pinned, header wording fixed and a new coverage
bullet added. Responsorial Psalm is deliberately still not emitted --
OLM 1981 Praenotanda n. 71 itself lists it apart from the readings
proper as a chant with its own refrain, and the finding driving this
change names only the missing Second reading.
EF output verified byte-identical to the branch start (empty
lib/rites/rite_ef + data/ef diff since v1.0.0, plus a direct binary
comparison of `day`/`readings` for 2026, 1583 and 9999 against a
worktree build of the pre-change commit).
Tests: three new fixtures in test_validate.ml prove the generalisation
holds both directions (a multi-shape rite accepts either of its
declared shapes; a rite that never declared a shape still rejects it).
test_citation_coverage_of.ml's pinned residual grows 41 -> 49, all new
entries the same already-understood chapter-crossing shape.

colitur readings --rite of printed "- | -" on 25 December every year
-- lectio's own 988 keys never included the Christmas DAY Mass at
all, only the Vigil (already correctly noted, but left unfilled, in
tools/bootstrap_lectionary_of.ml's own named_overrides comment).
Sourced, not guessed: docs/research/of/olm-1981-ocr.txt:4513-4520,
"16 Ad Missam in die", the same primary authority this module already
cites for the cycle rules. First reading and Gospel only, matching
this file's own scope everywhere else (First/Gospel is the kernel's
own boundary, I7, a separate deferred task) -- Isaiah 52:7-10 / John
1:1-18 (OLM's own LONGER form; the file's LINEAGE section already
discloses that short/long-form choices are not modelled anywhere in
this data, so this is an application of an existing limitation, not a
new one).
Injected via a new hand_authored table in the generator, merged into
entries before assert_reachable/Lectionary.of_entries -- there is no
ini section to derive this from. One new lookup_any call (readings'
own existing temporal-slug fallback, unmodified) now resolves BOTH the
formulary and the citations for 25 December from the same entry, so
both halves of the "citations-unresolved"/"formulary" gap close
together, not just the citation half.
Verified across the WHOLE domain, not assumed: test_validate_of.ml's
exhaustive sweep (COLITUR_EXHAUSTIVE_SWEEP=1, all 8 416 years) now
asserts the Nativity gap fires on NONE of them, down from all 8 416
before this fix -- and is kept as a live, dedicated "must never recur"
counter rather than deleted. test_rite_of.ml's landmark-year check and
test_lectionary_of.ml's 2026 coverage pins are updated the same way
(the unresolved-day set that used to be pinned as {25 December} is now
pinned as empty, not merely a count going to zero). A concrete golden
pin (test_golden_of.ml) locks the exact citations through the full
resolved pipeline. data/of/lectionary.sexp regenerated (771 entries,
was 770); its own SHA-256 re-pinned.
make check (COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force, unpiped,
foreground): exit 0, 895 tests, ~536s.

Fix option (c) from the I2 review finding, done alongside the parser
fix itself rather than deferred: tools/bootstrap_lectionary_of.ml now
runs every emitted reference through Colitur_citation.Parse.parse at
generation time and adds a fourth COVERAGE item plus a named listing
to data/of/lectionary.sexp's own header, so the 41-reference residual
(all chapter-crossing hyphen ranges, see the citation-fix commit) is
disclosed in the artifact a reader actually opens, not only in a task
report or test file.
Regenerated against the pinned lectio snapshot (dune exec
tools/bootstrap_lectionary_of.exe -- ../lectio/internal/caldata/
of-lectionary.ini data/of/lectionary.sexp); diffed against the
pre-change file to confirm the change is header-only, zero lines
removed, the sexp payload byte-identical. Re-pins the file's own
SHA-256 in test_lectionary_of.ml accordingly (re-derived with
sha256sum, not transcribed from generator stdout, matching that
test's own stated discipline).

data/dune's install stanza named only the four EF runtime files, so a
`dune install`ed colitur exited 2 on any --rite of invocation
(`failed to load .../data/of/calendar-2002.sexp`) -- the branch's
headline feature was dead on an installed binary. Add all 15 OF
files (calendar-2002.sexp, the 13 amendments/*.sexp, lectionary.sexp)
to the (files ...) stanza, following the existing ef/ entries' form
and the stanza's own stated rule (deliberately not the litcal
allow-list, a test fixture, same reasoning already given for the EF
pair).
Add a regression guard for the class of bug, not just this instance:
`make check-install` performs a real `dune install --prefix <scratch>`
and runs both rites against the INSTALLED binary, asserting exit 0
and the expected day count. test/cli.t's cram sandbox binds
%{bin:colitur} inside the build tree, where data_dir()/of_data_dir()'s
build-tree fallback candidate resolves even when the installed one is
missing entirely -- so no cram test could have caught this. Wired
into `make check` (unlike check-schema/check-templates/check-citations,
which skip when an optional external tool is absent) since installing
needs nothing beyond what building already needs. Verified the guard
has teeth: reverted data/dune to the pre-fix version and confirmed
check-install fails loudly naming the missing file.

golden pins
Task 6 (2026-08-25-colitur-of-phases-3-5), the final task of OF Phases 3-5.
Layer 2 (test/test_validate_of.ml, new): Colitur_kernel.Validate.run
against the real, assembled Rite_of.context -- landmark years, the 9999
domain edge, a 200-year QCheck sample, and the full 8417-year exhaustive
sweep under COLITUR_EXHAUSTIVE_SWEEP=1, all filtered through the same
three pinned-not-fixed gaps test_rite_of.ml already names (Normae n.35(a)
Holy Family fallback, the 25-December lectionary gap, St Joseph/Palm
Sunday), duplicated verbatim rather than shared so this file's own
filtering cannot drift from Task 5's silently. Two dedicated 200-sample
properties confirm Ordinary Time weeks are 1..34 with the final week
always 34, and Calendar.year covers its own liturgical year exactly once
with no gaps, both through the resolved pipeline (a genuinely different
code path from Phase 1's own already-exhaustive Temporal_of-level
property). An early version folded a second Calendar.year pass into the
exhaustive loop for these two properties too and measured ~365s for that
alone (a scratch timing harness, not committed); dropped in favour of one
Val.run-only exhaustive loop (~200s), matching the EF harness's shape
(one property, one sweep) rather than tripling it.
test/test_litcal_of.ml extended beyond season/week to GRADE (litcal's own
grade_lcl bucketed against the real Tabula band Precedence_of.band
assigns the day's observed office) and IDENTITY (observed slug against a
hand-verified event_key -> slug table for the closed 46-entity FIXED/
NAMED set -- deliberately not the numbered Sunday/weekday series, a
stated, counted scope limit). Both follow the counted-and-allow-listed
discipline: 1800/4346 rows compared for grade (1763 match, 37 allow-
listed across 5 new entries), 508/4346 for identity (505 match, 3 allow-
listed across 3 new entries), zero unexplained either way. Real
divergences found and adjudicated, not suppressed: litcal's own grade
vocabulary conflates Tabula I.2/I.3 for Trinity/Corpus Christi (verdict
colitur); litcal's Mary Magdalene data predates the 2016 CDW decree
(verdict litcal); a genuine, unadjudicated Sacred-Heart/Nativity-of-John-
the-Baptist tie-break at equal band, found live at the one Easter date in
this fixture's window that creates it (verdict open, no citation found
either way); a second instance of precedence_of.mli's own documented
forward-only transfer_target limitation, on a date shape the mli's own
worked example does not cover (verdict colitur, known limitation).
test/test_golden_of.ml (new, 7 pins): a year Ordinary Time skips a week
(2026) plus Mary Mother of the Church same date; Advent IV on Christmas
Eve in two independent years (2028, 2034); the Annunciation transferred
out of Holy Week to Easter+8 (2027, both ends of the transfer pinned);
All Souls; the Sacred Heart; 17 December's date-keyed reading in two
civil years/weekday-cycle letters.
Every new layer mutation-proved: reverting the Advent-IV fix reddens two
golden pins; corrupting Precedence_of.band's Tabula I.3 value reddens the
litcal grade comparator across every Solemnity in the fixture; renaming
one temporal slug reddens the litcal identity comparator; dropping
Ordinary Time's second season_runs entry reddens both the landmark-years
test and the sampled property. Each mutation applied to lib/rites/rite_of/,
confirmed red, then reverted -- git diff --stat lib/ is empty.
make check (COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force): exit 0, 890
tests, 363.5s. EF byte-identity holds: git diff --stat v1.0.0..HEAD --
lib/rites/rite_ef/ lib/kernel/ data/ef/ is empty.

Christmas-season dates
The bootstrap excluded 19 lectio bases as "date-keyed duplicates", but
17 of them were not duplicates at all: the 8 O-Antiphon days
(17-24 December) and 8 further Christmas-season dates (29-31 December,
2-5 and 7 January) each carry unique per-date content found nowhere else
among the emitted entries, verified against lectio's own ini directly.
17 December is Gen 49:2,8-10 / Matthew 1:1-17, but colitur was falling
through to that year's unrelated weekday-keyed "advent-3-mon" content
instead.
OLM n. 69.3 explains why: those ferias are fixed by civil date, unlike
every other Advent/Christmastide/Paschaltide feria, which is merely
non-alternating within a weekday slot. Temporal_of's own ferial slugs
for these dates are weekday-keyed, so looking one of those up served
whichever OTHER date happened to share that year's weekday alignment --
a citation that silently drifted year to year on ~16 real civil dates
(6 January stays excluded: Temporal_of fixes Epiphany there
unconditionally, so that date can never reach the ferial path at all;
two more, easter-6-thu and advent-4-sat, stay excluded for their own,
different structural reasons).
Fixed with a date-keyed lookup route (Lectionary_of.date_keyed_slug),
tried before the weekday-keyed one in readings' own step 3.
Temporal_of's slugs are unchanged -- only which lectionary key resolves
a day's citations. tools/bootstrap_lectionary_of.ml now maps the 17
bases to synthetic date-keyed slugs instead of excluding them, and its
own reachability sweep calls date_keyed_slug directly so the two can
never drift apart. Re-emitted data/of/lectionary.sexp (754 -> 770
entries) and corrected its provenance header, which previously
described these dates as excluded duplicates.
Also states, for the first time, a Minor finding from the same review:
190 of 222 shipped sanctoral slugs have no dedicated lectionary entry
and correctly fall through to the ferial per OLM norms -- expected
behaviour, not a gap, but never said in the coverage report before.
New tests pin 17 December (Gen 49:2,8-10 / Matthew 1:1-17) and 2 January
(1 John 2:22-28 / John 1:19-28) in two years with different weekday
alignments, proving neither reading drifts, plus direct boundary
coverage of date_keyed_slug itself (both windows, the 6 January
exclusion, and the Sunday guard).

Task 4 of Phases 3-5: the last Rite.t field OF still needed, `readings`.
The cycle rules are CODE, cited to OLM (Ordo Lectionum Missae) 1981
Praenotanda -- verified against the real page image
(docs/research/of/olm-1981.pdf pp.32-33/"XXXII-XXXIII"), not the
document's own unreliable OCR text layer, per the design spec's own
caveat. n. 66 (with its footnote 102's worked example, 1980=C/1981=A/
1982=B/1983=C) gives the three-year Sunday cycle; n. 69 point 4 gives
the two-year weekday cycle, Year I in odd label years, Year II in
even. Both derive the "label year" the same way: one more than the
civil year Advent I opened in, per n. 66's footnote 102 itself
("nempe a prima hebdomada Adventus, quae cadit in anno civili
praecedente") -- so the cycle turns at Advent I, not 1 January, exactly
where the task brief said to get it right. The design spec's own
citation for the weekday rule, "Praenotanda n. 649", does not survive
a direct check against the primary source (search finds "649" only in
unrelated index/page-number entries); corrected here to n. 69, the
paragraph the rule's own Latin text actually sits under, confirmed by
the page image's own printed margin number.
The data is bootstrapped from lectio's of-lectionary.ini (988 keys,
niedziela.pl, harvest 2020-2025) by tools/bootstrap_lectionary_of.ml
-- OCaml, not the brief's own suggested .py: tools/bootstrap_lectionary
.ml already established this exact shape for EF, including a real
safety net ([assert_reachable], sweeping Rite_of.Temporal_of.temporal
AND the real merged sanctoral layer directly) that a second-language
reimplementation would either duplicate or lose. Handles two real
data anomalies found while building it: one malformed ini line (a
Polish Septuagint-numbering annotation for Sirach 3, "Syr 3,2-6.12-14"
against OLM/CEI/USA's shared Nova Vulgata, matching the design spec's
own sec5 finding); and two Sunday-cycle-labelled bases (Annunciation,
Immaculate Conception) where a scraping-year artifact left one of
three cycle letters carrying a different day's Mass entirely --
resolved by a general, mechanical 2-of-3 majority rule, not a
per-saint hand edit, and logged.
Coverage measured in both directions, per the brief's own Step 1:
- 1 of 365 days in civil year 2026 (25 December, the Christmas DAY
Mass) has no Temporal_of-slug match anywhere in lectio's 988 keys --
only the Vigil is present. Named in the data file's own header.
- 0 of 438 distinct lectio bases map to no colitur slug, after 19 are
deliberately excluded (late-Advent/Christmas-season DATE-keyed
duplicates lectio also carries in a WEEKDAY-keyed form colitur's own
slugs actually match -- Lectionary.t has no date-keyed lookup at
all, so the date-keyed family is transcription-inert, not silently
dropped: named explicitly, not a residual).
Lectionary_of.readings is three steps (no Commons indirection, unlike
EF -- out of this task's scope): the observed celebration's own
embedded citations; else, for a real sanctoral winner, its own slug
looked up directly (flat, then both cycle letters); else the day's
own temporal slug, same lookup. No preceding-Sunday fallback: OF's own
two-year cycle assigns every Ordinary Time weekday its own reading by
design, and no OF norm was found instructing otherwise.
Tests (test/test_lectionary_of.ml, 12 cases): a cycle-arithmetic table
straddling Advent 1980/1981/1982/2025 inside single civil years,
reproducing OLM n.66's own worked example directly; SHA-256 pins on
both the emitted file and lectio's own source (embedded in the
provenance header); a pinned, NAMED 2026 coverage result (364 resolve,
exactly {25 December} does not -- never a bare count); two resolution-
chain spot checks (a plain ferial, and a saint's day beating the
ferial it would otherwise fall on); and a real subprocess test that a
missing lectio source file fails the generator loudly, non-zero exit,

Adds data/of/amendments/*.sexp: 13 overlay files, one per decree,
carrying the General Roman Calendar's amendments since the 2002 typical
edition (docs/research/of/PROVENANCE-amendments.md's own 15-item
inventory, items 10-12 sharing one decree; items 2 and 3, though issued
the same day, carry different protocol numbers and are counted as two
decrees). 14 Add directives (Padre Pio, Juan Diego, Guadalupe, John
XXIII, John Paul II, Mary Mother of the Church, Paul VI, Loreto,
Faustina Kowalska, Gregory of Narek, John of Avila, Hildegard of Bingen,
Teresa of Calcutta, John Henry Newman) and 2 Edit directives (Mary
Magdalene's rank memoria->festum; Martha/Mary/Lazarus's name widened,
same slug, same date and rank -- a continuation of the existing
memorial per the decree's own text, not a suppression and replacement).
Mary, Mother of the Church is the one movable entry (Easter_offset 50,
the Monday after Pentecost) -- verified against the decree's own text
and against Colitur_kernel.Computus.gregorian_easter in three real
years, no kernel change needed.
data/of/calendar-2002.sexp is untouched, per spec sec4.1.
Adds test/test_amendments_of.ml: every file parses, each has a pinned
SHA-256, applying all 13 in decree order yields 222 entries (208 base +
14 Add) with an empty Overlay.merge diagnostics list, and Mary Mother of
the Church resolves to the Monday after Pentecost in three real years.
Two Precedence_of interactions are recorded, not fixed (out of scope for
a data-only task): a movable Memoria_obligatoria can land on an existing
fixed one (verified for 13 June 2011), a genuine band tie Normae n. 14
does not address and Precedence_of.ml does not implement; and adding
Hildegard of Bingen changes which of two ad-libitum memorials on 17
September Precedence.resolve reports as observed, by alphabetical
tie-break alone.

Four fixes from fix round 2 review:
classify_subject's "maria"/"b.m.v" substring test over-matched 12 saints
who merely carry "Maria" in their own name (Maximilian Mary Kolbe, John
Mary Vianney, Mary Magdalene among them) as Bvm. Replaced with an
explicit BVM_DATES table of the 13 genuinely Marian entries. Bvm 25 -> 13.
The provenance header claimed lectio is "never a source", which omitted
that slugs and English names both come from it. Corrected to state
exactly what does (slugs, en names) and does not (every substantive
field) come from lectio. A missing lectio file used to degrade silently
to a different SHA-256 with no en names and no warning; it now fails
loudly. lectio's own SHA-256 is now pinned alongside the Missal PDF's.
Four more entries carried a second pdftotext artifact distinct from the
letter-spacing already handled -- a combining diacritic rendered as a
stray spacing character (Kim Taegŏn/Chŏng Ha-sang, Đũng Lạc, Makhlūf,
Kęty). Hand-repaired the same way Peter Damian was, each corroborated by
the identical corruption recurring in the Missal's own index.
precedence_of.ml's PHASE 3 HAZARD comment about All Souls (2 November)
was asserting a gap that no longer exists now that OF sanctoral data
ships. Added test_all_souls_beats_an_ordinary_sunday, which resolves the
shipped All Souls entry against a real per-annum Sunday (2025-11-02)
through the actual Precedence.resolve pipeline, and updated the comment
to record the resolution instead of demanding it.

Both are printed in the 2002 calendar table, immediately after 30 June, as
prose headings rather than (kalends, day) rows -- the shape parse_rows'
generic movable-heading skip branch was built for, which is why the first
pass silently dropped them. They belong in the transcription, not in
Temporal_of: adding them completes the table this file transcribes rather
than amending the temporal cycle.
Produced as Date_spec.Easter_offset entries (68 and 69 respectively), the
same variant already used for EF's Rogation Wednesday and needing no
kernel change. Pentecost is Easter+49, so the Friday and Saturday after
the Second Sunday after Pentecost are Easter+68/+69 -- verified against
three real Easter dates (2026, 2027, 2035), not merely computed on paper.
The extractor now recognises these two headings specifically among the
seven "Dominica/Feria/Sabbato ... :" headings the table contains; a full
audit of the other five confirms each is already covered by Temporal_of
and correctly stays excluded here. 206 -> 208 entries.

Extracted from the Latin typical edition, which is the authority; lectio's
roman-calendar.ini is a cross-check only and every divergence is adjudicated
against the Missal in the provenance header.
A blank grade column means Memoria ad libitum, per the calendar's own
footnote, rather than a missing value. 206 entries; 1 January, 6 January and
25 December are deliberately excluded because Temporal_of.named already
computes them, and shipping them here too would create a duplicate
candidate for the same day.
Colour is derived from IGMR n. 346, cited per class in the extractor; the
lectio cross-check surfaces one rank divergence (22 July, Mary Magdalene --
lectio reflects the 2016 post-2002 elevation decree, out of scope here) and
17 colour divergences, all adjudicated in the provenance header.

Adds a sixth-lineage external validation layer for the OF rite module's
Phase 1 temporal cycle, targeting the single highest-risk function that
report named: the two-block Ordinary Time week arithmetic (Normae n. 44),
which has no external witness anywhere in Phase 1's own suite and whose
output selects the Mass formulary, not merely a label.
Witness: litcal (Liturgical Calendar API), Apache-2.0, already archived
and SHA-256-pinned by the sibling lectio project. AELF was considered and
correctly excluded earlier (its CGU forbids redistribution) -- litcal is
what it was replaced with.
- tools/extract_litcal_ordo.py verifies all twelve archived
calendar-YYYY-en.json files (2024-2035; the task brief said eleven,
but twelve are actually pinned in lectio's manifest -- all twelve are
used) against lectio's own manifest.tsv, then builds one fixture
spanning the contiguous 4382-day range those twelve liturgical-year
files cover.
- test/fixtures/litcal-temporal-2024-2035.sexp: one row per day, season
and (where witnessed) Ordinary Time week, with full provenance,
licence, per-year Easter dates and the row-selection rules in its own
header.
- test/test_litcal_of.ml calls Temporal_of.temporal directly (no Rite.t)
and compares 1:1 against the fixture: zero Ordinary Time week
mismatches on all 1876 witnessed days (zero tolerance, no allow-list);
the only season divergence class is the Sacred Triduum, which litcal
tags with a season value colitur's vocabulary deliberately has none of
-- one cited allow-list entry, data/of/expected-divergences-litcal.sexp,
36 rows, exact.
- Mutation-tested: dropping the backward-from-34 adjustment reddens this
layer (1511 of 1876 days) plus three pre-existing Phase 1 tests; the
mutation was not committed.
Does not touch lib/rites/rite_ef/, data/ef/, or lib/rites/rite_of/ --
this validates Phase 1, it does not change it. Full suite: 786 tests via
dune test, 791 via make check, exit 0 both; lib/bin diff empty throughout.

Both entries reasoned correctly that these feasts are not in the universal
calendar, then recommended adding them to CLAUDE.md's list of sanctoral
entries MISSING from colitur. Those cannot both be true, and acting on the
recommendation would add a particular-calendar feast to the universal core
-- what binding decision 2 exists to forbid.
The Missal classifies both itself, under "Missae pro aliquibus locis":
scan1.txt:52019 for the Miraculous Medal, 48793 for St John before the
Latin Gate. Masses for some places.
So they are not gaps. They are particular feasts colitur correctly excludes
and an overlay would supply, the shape poland.ini and benedictine.ini
already demonstrate; the ordos carry them because those ordos serve
communities that keep them. Verdicts unchanged, now resting on the Missal's
own words rather than on background knowledge of the apparition.

Extends the preface comparison (RG 482-499) with a third, independent
publisher, extraordinaryform.org's three annual Ordo editions
(2024-2025, 2025-2026, 2026-2027), previously declined for two reasons
that are now resolved:
- "Advent" is not a preface: RG 494(b) grants the Trinity preface on
every Advent SUNDAY, RG 498 the residual Common on every Advent
FERIA; this source's own "Advent" label covers both indiscriminately
(confirmed live on all 11 non-impeded Advent Sundays in the corpus).
Classified by the day's own civil weekday, not a static table.
- The known Vigil-of-St-Lawrence gap is reconfirmed, with a nuance not
present in the earlier audits: colitur's own RG33-third-trigger now
omits the vigil in some years too, so the corpus's gap and colitur's
answer coincide in 2025 (a full match, not a coincidence) while 2027
still shows the classic identity-wrong-but-preface-invisible shape.
Re-derives the known menu-trap office filter (Requiem-skip, "and "-chain)
against the live JSON and finds a second, general pattern: "Saturday of
Our Lady" (RG78's BVM Saturday Office), whenever listed, is
unconditionally the office -- checked exhaustively across all 38
instances in the corpus, zero counter-examples. A third, generic
"absorption" rule was deliberately not built: it would resolve 2 of the
11 residual divergences but wrongly misfires on a structurally identical
but semantically different shape (an optional Rogation-day Mass option).
The JSON's own extraction carries a genuine classifier gap: parse_ordo.py's
hardcoded PREFACES set omits "Christ the King", misfiling it into comms;
recovered in the generator, not left blank.
11 of 1088 comparable rows diverge, resolving to 7 adjudicated root
causes (E1-E7): two Commemoration_only Marian titles reduced to
commemorations (Mt Carmel, Ransom), two genuine sanctoral data gaps
cross-confirmed absent by the FIUV/LMS witnesses (Miraculous Medal,
St John before the Latin Gate), two single-witnessed efdotorg outliers
against FIUV/LMS agreement (St Michael's Dedication, All Saints on a
Sunday), and one isolated source labelling slip.
Mutation-tested: corrupting the RG495 BVM-Saturday clause reddens 9
tests across this new layer and both existing Ordo witnesses.
Per-edition agreement: 358/363 (2024-2025), 358/363 (2025-2026),
361/362 (2026-2027).

Ascension has no octave under the 1960 rubrics -- confirmed structurally:
the Proprium de Tempore's own table of contents runs straight from "In
Ascensione Domini" to "Dominica post Ascensionem" with no per-feria
headings in between. Step 3 of the reading chain therefore fell through
to Preceding_sunday on every unoccupied weekday in that stretch, walking
each one back to the 5th or 6th Sunday after Easter's own citation.
The Missal's own Proprium de Tempore carries an explicit marginal rubric
immediately after the Ascension's Mass propers, before "Dominica post
Ascensionem" begins: "Diebus a feria VI post Ascensionem usque ad feriam
VI ante vigiliam Pentecostes inclusive, dicitur Missa de festo
Ascensionis, cum Gloria et praefatione de Ascensione, sine Credo et
Communicantes proprio" -- every feria without its own proper, from the
Friday after the Ascension through the Friday before the Vigil of
Pentecost, repeats the Ascension's own Mass. RG 490(b) corroborates
independently: it assigns the Ascension preface "tamquam de Tempore"
across that identical window, which only makes sense if the Mass
actually repeated there is the Ascension's, not a numbered Sunday's
(whose own Mass would carry no need for a preface override at all).
Witnessed directly, not only inferred from the rubric: the LMS Ordo
prints "Mass of the Ascension" literally on every affected day across
all three of its fixture windows, in BOTH the tail of Ascension's own
week and the following week -- ruling out the alternative reading (that
the second week instead resumes "Dominica post Ascensionem"'s own Mass,
which a first pass over the FIUV Ordo's own week-labelled titles could
suggest at a glance; its own [praef] field for the same two dates
independently reads "Ascensionis", resolving the apparent conflict).
Implemented as data, not logic, matching this codebase's own established
precedent for the identical RG 299 shape (the week after Trinity Sunday,
data/ef/lectionary.sexp's [trinity_week_entries]): six new hand-authored
entries, [ascension_week_entries] in tools/bootstrap_lectionary.ml,
regenerated against a git-pinned copy of lectio's own source ini (SHA-256
verified unchanged) so the regeneration carries no unrelated drift. The
window's two Saturdays are deliberately excluded -- RG 78's votive Office
of Our Lady on Saturday always wins an otherwise-unoccupied Class4
Saturday first, before step 2 (this fix's own entry point) is ever
reached, so an entry for either slug would be dead data.
Blast radius measured in-process across the full 1583-9999 domain
(throwaway probe, not committed): 16 350 days total across the six
slugs, every one resolved via step 2 (Own_slug), zero anomalies, and the
window's two Saturdays confirmed to contribute zero hits via this cause
across the whole domain, corroborating the RG78-interception reasoning
by direct sweep.
Closed L2 in data/ef/expected-divergences-lms.sexp. New cited entries:
C41 in data/ef/expected-divergences.sexp (95 of 16801 rows, 2005-2050 --
lectio has no equivalent rubric and still walks these ferias back);
M31 in data/ef/expected-divergences-missalemeum.sexp (3 rows in the
2026-2027 window, plus the same shape independently reconfirmed in the
2035 and 2038 live-capture windows) -- missalemeum, Divinum Officium's
lineage, still gives the same wrong answer colitur itself used to give,
which is why these rows used to agree with M18's shape and now escape it
(M18 373 -> 370, the same mechanism M23-M27 established when the
citation axis was first built).
Golden pin: 2031-05-23, the exact date the bug report was filed against.
Mutation-tested: reverting data/ef/lectionary.sexp alone (a git-diff
capture/restore, not a source-code revert, since the fix is data) reddens
19 tests across the differential, both oracle fixtures, all three LMS
Ordo windows, the golden pin, the lectionary unit test and every Render
golden template; restored and reconfirmed green (681 tests; 683 under
COLITUR_EXHAUSTIVE_SWEEP=1, ~175s).

Temporal_ef.temporal's Rogation Monday/Tuesday branch hardcoded
Colour.Violet with no citation (data/ef/expected-divergences-lms.sexp's
L6, surfaced by the LMS Ordo). RG 119 assigns white to the de-Tempore
Office and Mass from the Paschal Vigil Mass to the Pentecost Vigil Mass
exclusive; Easter+36/+37 sit inside that window. RG 128's own exhaustive
four-case violet list never names Rogation days, and its vigil clause
(d) is doubly inapplicable: these are not vigils, and they are inside
Paschaltide, not outside it. RG 88 explains the violet actually seen in
print sources: "de Litaniis minoribus nihil fit in Officio, sed tantum
in Missa" -- the violet belongs to the Rogation Mass/procession, a
distinct votive text this engine does not model, not to the day's own
Office. Witnessed directly: LMS Ordo 2023-2024, 2024-05-06, "FERIA IV Cl
W" with "Gl", the Office and Mass printed separately from the optional
violet votive Mass of the Rogations.
Cascade verified, not assumed: RG 432(b) omits the Gloria on every
violet Mass, so the wrong colour was also silencing the Gloria on these
two weekdays even though RG 237(e) (Breviary, ordinary Paschaltide
ferias say Te Deum) already made it true underneath. White removes the
432(b) block, and the Gloria now follows Te Deum via 431(a), matching
the Ordo's own "Gl" -- confirmed with dedicated golden pins in both
test_golden.ml (colour) and test_rubrics_ef.ml (the Gloria flip),
2028-05-22/23 (neither day impeded that year).
Closed L6 in data/ef/expected-divergences-lms.sexp. Reopened C8 in
data/ef/expected-divergences.sexp (26 of 16801 rows, 2005-2050): lectio
independently computes these two days violet too, so the two engines
used to agree by sharing the same uncited assumption; colitur's colour
is now correct and lectio's is not, so the comparator disagrees again,
for the opposite reason. While reopening C8, found and corrected a
genuine misattribution in its own prior closure note, which claimed
lectio's violet was "RG 128(d)" -- 128(d) governs vigils outside
Paschaltide and has nothing to do with Rogation days. Checked
docs/research/rules-register.md for the same claim: not present there,
but a related conflation was found and corrected at its O'Connell
section 4(d) note, which had used a Rogation MASS/procession citation to
"confirm" the day's own OFFICE colour.
Blast radius measured in-process across the full 1583-9999 domain
(throwaway probe, not committed): 4722 days total (2368 Rogation
Mondays + 2354 Rogation Tuesdays actually observed outright, i.e. not
impeded by a stronger sanctoral feast that year), all Violet->White,
all with the Gloria flipping false->true alongside, zero anomalies.
Mutation-tested: reverting the branch to Colour.Violet reddens 16 tests
across Rubrics_ef, the lectio differential, the LMS Ordo suite and both
golden pin files; restored and reconfirmed green (680 tests).

data/ef/expected-divergences-lms.sexp's L5 (16 dates, LMS Ordo Gloria=true
vs colitur's false) and data/ef/expected-divergences-fiuv.sexp's F3 (6
dates, FIUV Te Deum=true vs colitur's false) were both misadjudicated as
colitur's own gap under an RG 302(b)/431(b) hypothesis. Both are wrong.
These are occurrence differences from the 2020 decree Cum Sanctissima,
which colitur excludes from its 1962 core by binding design (CLAUDE.md
decision 2). RG 303(b) ("dici potest tantum si occurrit dies liturgicus IV
classis") already prohibits 302(b) on the Class3 privileged ferias both
entries cover -- the original text quoted 303(b) but never followed it to
its conclusion. Decisively, the FIUV Ordo prints BOTH readings on the six
shared dates, separated by a literal "-VEL-" token: the primary, strict-
1962 reading (feria wins, sine Gloria, no Te Deum) matches colitur exactly;
the second, Cum-Sanctissima reading (saint kept, Gloria, Te Deum) matches
the LMS Ordo exactly.
F3 itself was never a real Te Deum finding: tools/extract_fiuv_ordo.ml's
extract_te_deum scanned each block unbounded for "Ad Mat.", so on these six
days -- whose primary office states no "Ad Mat." of its own -- it silently
read the second office's own Te Deum instead. Fixed with a new
split_at_alt_office, cutting every block at "-VEL-" before any field
extraction runs; the alternative is captured, not discarded, in a new
alt_te_deum field. A hard characterisation probe asserts the split fires on
exactly the six known dates.
Auditing for the same trap elsewhere (this is the third such manufactured
divergence in this project) found a related but narrower marker, "Vel (sec.
decretum <<Cum sanct.>>) Missa ...", offering an alternate Mass formulary
within a single office. It never corrupted Gloria/Credo (always stated
before the marker on all 20 real instances, confirmed by diff), only the
uncompared praef field; hardened defensively anyway, before it could ever
fire live. The LMS Ordo (all three editions) carries no equivalent
dual-print mechanism at all. expected-divergences-missalemeum.sexp's M27
is the same genus but was already correctly adjudicated, not touched.
Both allow-list entries are rewritten, not deleted: the original SHAPE/
CITATION/WHY-NOT-FIXED-HERE reasoning is preserved verbatim as a recorded,
superseded hypothesis, matching this project's own correction convention.
test_lms_ordo.ml's matching predicate is unchanged (the 16-date population
still fires, and always will, because it reflects a standing exclusion,
not a bug); only its citation comment is corrected. test_fiuv_ordo.ml's
F3-specific predicate/count assertion is removed, matching this file's own
prior F2/F4 closure discipline.
lib/ is untouched. dune test: 676/676. make check

F1 adjudicated the FIUV ordo's Good Friday "Gloria" against the ordo, but
rested on external attestation and left a pdftotext misread unruled-out.
The page image resolves both.
The extraction is faithful: the printed book does carry that line. So the
adjacent-block-misread possibility is ruled out rather than merely doubted.
And the same page shows the compiler knew the distinction. Holy Saturday,
its next entry, carries no Mass line at all -- correctly. Easter, the entry
after, carries a full one -- correctly. Good Friday, which likewise has no
Mass, wrongly receives one, word-for-word identical to Holy Thursday's on
the preceding page, while its own Vespers rubric four lines below calls the
day's rite an Actio liturgica rather than a Mass.
Verdict unchanged. It now rests on internal evidence from the source rather
than on every other authority disagreeing, which is the footing this
project's own standard asks for.

Phase 2 of celebrant-rubrics-phase1: colitur rubrics gains a fifth
column, whether the Gloria is said. Follows the Creed's own seam
exactly -- Rite.t.gloria, Liturgical_day.t.gloria, wired through
calendar.ml the same way.
RG 431(a)/432(a) defer the Gloria to the Breviary's own Te Deum rule
(nn. 237-238), so te_deum is implemented as its own named predicate,
cited clause by clause, not collapsed into a colour heuristic. 431(c)
(Holy Thursday, the Easter Vigil Mass) and 432(b)/(d) (violet; a
Requiem) are independent overrides checked ahead of the Te Deum-derived
answer. Every clause this engine has no dimension to model
(votive Mass classes, the wider n.302 "Missa festiva" categories) is
stated as N/A with its own reasoning, not silently dropped.
Validated against the FIUV universal Ordo (Gloria and Te Deum) and all
three LMS editions (Gloria). A first pass over-trusted a clean-looking
15-for-15 FIUV contradiction of 237(b)'s own Septuagesima exception and
replaced it with a blanket "every Sunday" rule; the evidence was itself
corrupted -- the FIUV extractor recognised only one of the source's two
Te Deum negations ("non dicitur", not "sine"), so every "sine Te Deum"
Sunday read wrongly true. Fixed in tools/extract_fiuv_ordo.ml, fixture
re-extracted, and the literal 237(b) reading restored once the
corrected data confirmed it. A second bug surfaced alongside it (Palm/
Passion Sunday wrongly reading true via Temporal_ef.named's own table
membership, then Christ the King wrongly reading false from an
over-broad fix) is closed with an explicit two-slug exclusion.
Domain-wide 1583-9999: every violet or Rose day is gloria=false except
the Easter Vigil (RG 431(c) lex specialis), every Requiem is
gloria=false, both measured exhaustively, zero exceptions. Mutation-
proved: disabling 431(c) reddens 8 tests including all four oracle
comparisons; disabling 238(c)'s feria-I-classis exclusion reddens
exactly the dedicated Ash Wednesday unit test, a genuine blind spot in
both oracle layers, reported rather than hidden.
Two open, cited findings, neither fixed here (out of this task's
"follow creed's exact seam" scope): a privileged Lenten/Passiontide
feria carrying one commemoration reads Gloria=true in the LMS Ordo but
Te-Deum=true/Gloria=false in FIUV -- the two oracles disagree with each
other, not merely with colitur (data/ef/expected-divergences-lms.sexp
L5, expected-divergences-fiuv.sexp F3); and a pre-existing, uncited
Colour.Violet bug on Rogation Monday/Tuesday in Temporal_ef.temporal,
surfaced by this comparison but root-caused as a separate defect (L6).
day/readings verified byte-identical against a build from the branch
tip before this task (v0.10.1's own tag predates an already-landed
bissextile fix that legitimately changed both, so it is not the right
baseline).
671 tests green (dune test); 678 with the exhaustive sweep
(COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force, ~104s).

The Missale Romanum's calendarium footnote for February (LT.txt:5011-5014,
scan-corroborated scan2.txt:3050-3058): in a leap year the sixth kalends of
March (24 February) is doubled rather than a 29th day appended, so St
Matthias moves 24->25 February and St Gabriel of Our Lady of Sorrows
27->28, with 24 February itself carrying no fixed office that year.
data/ef/expected-divergences-lms.sexp entry L3 tracked this as an open gap.
Implemented as the rubric's own general mechanism (every fixed entry from
24 through 28 February shifts one civil day later in a leap year), not as
"move these two named saints": the two readings are indistinguishable on
shipped data (nothing else is fixed in that window) and diverge only for a
future --overlay entry in the same range, which the mechanism reading
covers correctly and a two-saints special case would not. This project has
already been bitten once (RG 16(a)) by a rule implemented against shipped
data's coincidental shape rather than the rubric itself.
Kernel stays rite-agnostic: Rite.t gains a fixed_key field (Date.t -> (int
* int) option), the same seam easter already establishes, read only by
Layer.on_date's FIXED half -- the movable half (Easter_offset/Nth_weekday)
is untouched. Default is the identity mapping, an optional argument on
on_date, so every existing caller and every rite that supplies nothing is
byte-identical to before this field existed. Date.is_leap is exposed in
date.mli (already existed in date.ml) so the rite reads the kernel's own
single-sourced leap-year definition. The EF implementation lives in
Rite_ef.Temporal_ef.bissextile_fixed_key, fully cited, wired into
Rite_ef.context.
Blast radius, measured over the full 1583-9999 domain (Calendar.year run
twice per civil year, real fixed_key vs identity, every day diffed): all
2,041 leap years in the domain show a visible change for each saint;
6,983 individual liturgical days change total, zero unclassified, across
four shapes (Matthias vacates 24 Feb in 1,803 years / occupies 25 Feb in
1,811; Gabriel vacates 27 Feb in 1,699 / occupies 28 Feb in 1,670).
L3's own prior estimate (1,650 years, observed-outright only) is confirmed
close on the same definition (1,677 measured); the broader observed-or-
commemorated count is higher, not lower, showing the narrow estimate
undercounted visible impact rather than overcounting it.
The lectio differential (2005-2050 fixture) gains a new cited entry, C40
in data/ef/expected-divergences.sexp: lectio implements no such shift, so
every leap year in its window now diverges on the two shifted days (21
rows, not the naive 44 -- the comparator never compares commemorations, so
a side where the shifted saint has zero comparator-visible footprint on
both engines produces no row). The LMS Ordo's 2023-2024 fixture -- the
window L3 was originally found in -- now matches on the Creed comparison;
its formulary-override bucket count is corrected 182->181 (24 February
leaves the counted Proper population, becoming Own_slug-sourced). The
missalemeum oracle fixtures (2026-2027, 2038, 2035) cover no leap year and
are unaffected.
L3 is closed: converted from an active allow-list record to a prose
closure paragraph (L1's own precedent), citation preserved verbatim, fix
and measured blast radius recorded. The id-list assertion narrows to [L4]
alone, and the now-dead "2024-02-24" -> "L3" date mapping is removed.
Six golden values pinned across four new test cases: Matthias in a leap
year (both the vacated and occupied sides) and a common-year control;
Gabriel likewise, deliberately choosing a leap year where he is admitted
only as an ordinary commemoration rather than winning outright, a
different shape from Matthias's.
Mutation-tested: forcing fixed_key back to identity reddens exactly five
test cases -- the differential's Layer C count-pin (C40 drops to 0 actual
vs 21 expected), the LMS Ordo's Creed and formulary-bucket checks, and
both new golden pins -- confirming the tests actually exercise the fix.
Reverted; dune test, the exhaustive sweep, and make check are all green.

L3 recorded that the leap-year shift rested on the LT.txt transcription
alone, the scans having been searched without result. It is in scan2.txt
at 3050-3058, OCR-damaged but unmistakable.
The earlier search missed it for a findable reason, now written into the
entry: the OCR mangles the saint and the keyword alike -- "Matthue",
"Cabrielis", "bi&sextili" -- so neither "Matth" nor "bissext" matches. It
turns up on the undamaged phrase "februarius est dierum".
Transcription and scan now agree, which makes this two witnesses of one
document rather than one. Still one document; the citation continues to say
calendarium rather than RG, because a calendarium footnote is what it is.

Wires in the FIUV (Foederatio Internationalis Una Voce) Ordo for
2025-2026 as validation layer seven -- the first UNIVERSAL (not
diocesan) source in this project, and the first compiled by someone
other than the LMS editions' own Peter Day-Milne (Joseph Shaw, FIUV
President).
tools/extract_fiuv_ordo.ml hand-parses pdftotext's -layout dump of the
Latin-language ordo (no Str/regex, frozen deps). Three real parsing
traps were found and fixed by tracing actual false results against the
raw source, not assumed in advance:
- "Gloria" is also the first word of "Gloria Patri" (the psalm
doxology), which can appear INSIDE the very Mass clause being scanned
(Good Friday: "...omittuntur ps. Iudica me et Gloria Patri), Gloria,
sine Credo..."). Guarded by rejecting any "Gloria" hit whose next
token is "Patri".
- Christmas Day's own rubric uses the PLURAL "Missae"/"Missae" ("tres
Missae celebrantur..."), never the singular "Missa" every other real
day anchors on -- silently produced gloria=None/credo=None on the one
most doctrinally unambiguous day in the calendar until traced and
fixed, guarded in turn against "Missae defunctorum" (an unrelated
Requiem-prohibition notice appearing at the end of many day-blocks).
- The Vespers boundary (bounding the primary Mass option before a
second "Vel Missa" alternative or before Vespers information) missed
the ligature spelling "VESPERÆ", the dominant form in this source,
letting a whole day's trailing prose leak into the captured [praef]
field on the task brief's own worked example day (19 September).
A distinct second stop-marker bug: the malformed trailing entry this
source shares structurally with the LMS PDFs (a stray, mislabelled
duplicate of 1 January) was initially over-matched by a generic
"first token is 4 digits" heuristic, which false-positived on an
indulgence-decree date citation wrapped mid-sentence in October
("...20 augusti / 1885, 26 augusti 1886..."), truncating the extraction
to 308 of 400 real days. Fixed by anchoring on the tail entry's own
distinctive "1st Jan" opening instead.
Five opposite-prediction Creed probes are re-verified by the tool
itself against its own extracted rows (a failed probe is a hard exit,
not a printed claim) before the fixture is written.
test/test_fiuv_ordo.ml compares the Creed against colitur across all
399 comparable days (Holy Saturday excluded, no Mass that day) --
CLEAN, zero unexplained divergences, a genuine second confirmation of
{!Rite_ef.Rubrics_ef.creed} independent of the LMS lineage. [praef],
[te_deum] and [class_] (including the FIUV ordo's own "III cl." vs
"III cl. (Priv.)" Cum Sanctissima convention, stated on its title
page) are captured into the fixture but deliberately not compared --
colitur has no Gloria/preface predicate yet, and its default
configuration models no Cum Sanctissima overlay to compare the class
convention against.
All 634 tests green (dune test), 635 with the exhaustive sweep and
make check. No lib/ file touched.

Generalises tools/extract_lms_ordo.ml's start-of-body detection: the
hardcoded "End of November 2024" sentinel assumed every edition opens
with an "End of November" stub section. The 2023-2024 edition has none
(Advent Sunday 2023 fell on 3 December, so the compiler folded the two
tail days into the "December 2023" header directly) -- the generalised
detector anchors on the body's own "ORDO" title line instead, verified
unique in all three known editions and distinct from the Table of
Contents' lowercase "Ordo" entries.
Extracts test/fixtures/lms-ordo-2023-2024.sexp (397 rows) and
lms-ordo-2025-2026.sexp (399 rows), each with a provenance header
carrying its own SHA-256, source citation, and a per-edition
characterisation record: five opposite-prediction Creed probes,
independently re-verified against this run's own extracted rows (a
failed probe is now a hard die, not a printed claim). The 2025-2026
edition needed a different sharp II-class pairing than 2024-2025's
Joachim/Stephen one, because Joachim (16 August) is impeded by a Sunday
that year -- recorded in the fixture header, not silently swapped.
test/test_lms_ordo.ml is refactored into a parameterised make_suite,
instantiated once per edition; every count Task 6 hardcoded against the
single 2024-2025 window is now a per-edition parameter, several of which
turned out to differ once measured (BVM-Saturday population 12/14/13,
Ascension-week exclusion 1/3/2). Two mapping gaps surfaced only by the
new windows and fixed here (test-side, not colitur): Low Sunday reached
via Preceding_sunday for the first time (absent from 2024-2025's own
window), and the Ascension-week exclusion was wrongly keyed off week
number alone -- Rogation Monday also resumes week 6's Sunday but falls
BEFORE Ascension, not after, and the Ordo prints the ordinary Sunday
text there. Re-bounded by date, against Ascension and Pentecost.
Two genuine divergences surfaced in the 2023-2024 window and are
allow-listed (L3, L4) rather than fixed, per this task's no-lib-changes
scope:
- L3 (verdict ordo): colitur has no bissextile calendar rule. The 1962
Missal's own calendarium moves St Matthias from 24 to 25 February in
leap years (docs/research/LT.txt:5011); colitur keeps him on the 24th
every year. Domain-wide upper bound measured with a throwaway sweep:
1,650 of 2,041 leap years in 1583-9999 currently observe him there.
- L4 (verdict open): Christmas Eve falling on the 4th Sunday of Advent
(2023-12-24, roughly 1 year in 7). colitur says the Creed is said,
reading RG 475(a)'s Sunday clause; the Ordo says it is not. RG 30(a)'s
own "locum tenet ... nulla fit commemoratio" for this exact vigil
reads like RG 16(a)'s Feast-of-the-Lord-on-Sunday shape, which colitur
already treats as Creed-preserving -- but RG 475(a) names "festo"
specifically, and a vigil is its own liturgical-day category (RG 35),
so the counter-reading is real too. Left open rather than adjudicated.
All 630 tests green (dune test), 631 with the exhaustive sweep.

colitur said the Creed IS said on All Souls' Day and every other
Requiem-shaped day: RG 475(b)'s "in festis I classis" branch fired on
rank alone, with nothing checking RG 476(f), "Non dicitur symbolum ...
f) in Missis defunctorum". Allow-listed as L1 in
expected-divergences-lms.sexp on the argument that [creed] has no
notion of a Requiem Mass in its inputs and could not express the rule
without a signature change.
That argument does not hold. Colour.Black is used by exactly two
celebrations in the whole engine, verified by grepping every
occurrence in lib/ and data/: commemoration-of-all-souls
(data/ef/sanctoral.sexp) and Good Friday (temporal_ef.ml, already
false via the earlier RG 23(b) feria exclusion and has no Mass at all
in the 1955-restored Holy Week). So on every day this engine can
construct, colour = Black if and only if the Mass is a Requiem -- a
citable implication (RG 117 assigns black to Masses of the dead) on
this data, not a heuristic.
Rite_ef.Rubrics_ef.creed now reads observed.colour as RG 476(f)'s own
guard, positioned ahead of 475(b)'s rank branch. A new test,
test_colour_black_population_is_exactly_two, sweeps both the shipped
data and Temporal_ef's own code across a century and fails loudly the
day a third Colour.Black celebration is ever introduced, so the proxy
cannot silently rot.
L1 is closed in expected-divergences-lms.sexp, citation preserved.
Blast radius, measured (full 1583-9999 sweep, grouped by observed
slug): 8 416 days change from true to false, every one
commemoration-of-all-souls (missing from exactly 1 of the 8 417 domain
years, a boundary-year transfer effect at 1583/9999). A further 8 416
Colour.Black days are Good Friday, unaffected (already false before
this fix). colitur day/readings stay byte-identical to v0.10.1
(checked directly against a v0.10.1 worktree build, 9 domain-spanning
years); colitur rubrics changes on exactly the 8 416 days above.
colitur emit --format sexp's pretty-printed line count for 2027 moved
9010 -> 9011 as a side effect: Sexplib.Sexp.to_string_hum wraps by
column width, and All Souls' Day 2027's record grew one wrapped line
because "false" is one character longer than "true". Cosmetic only --
no field's data changed -- and pinned in test/cli.t with the
measurement recorded.

An independent lineage -- neither Divinum Officium, missalemeum nor
lectio -- covering the Mass formulary and the Creed. Characterised
before use, per the discipline the extraordinaryform.org Ordo's
blanket St Lawrence vigil gap taught this session: five opposite-
prediction Creed probes (Sunday/feria, octave-override vs plain
II-class, I-class) all confirmed against the raw extracted text
before a single divergence was adjudicated, recorded in the
fixture's own provenance header.
tools/extract_lms_ordo.ml hand-parses pdftotext -layout output (no
Str/regex, frozen deps) into test/fixtures/lms-ordo-2024-2025.sexp,
400 day-rows (2024-11-27..2025-12-31). Gl/Cr print per Mass-option,
not per day; the extractor takes the first pair in reading order,
which the source's own layout guarantees is the universal entry's,
since a diocesan variant always follows it, never precedes it. The
Ordo's I-V roman numeral ("Missae de sancta Maria in sabbato", RG
309(a)) is matched whole-line only, never by substring -- "V Mass of
BVM" is a substring of "IV Mass of BVM".
test/test_lms_ordo.ml compares two axes 1:1 by date:
- the Creed (RG 475-476): 399 of 400 days comparable (Good Friday
has no Mass at all, asserted as the only such day); one genuine
divergence, adjudicated to the ORDO, not colitur -- All Souls'
Day 2025-11-03 is a Requiem Mass, and colitur's own creed
predicate has no notion of one, a pre-existing scope gap
rubrics_ef.ml already documented in its own header before this
task existed.
- the BVM-Saturday seasonal Mass selection, the addendum's own
"sharper check": all 14 Votive days in the window match their
season's own numeral exactly, both directions, independently
re-derived from RG 309(a) rather than calling colitur's private
function.
- the formulary override, for the three sources it can honestly
discriminate (Proper 179, Preceding_sunday 66, Common 2, all
clean); Own_slug (139) is excluded with evidence, not silently --
several ferial slugs carry citations byte-identical to their
Sunday's own, so the Ordo's override line cannot distinguish the
two representations.
data/ef/expected-divergences-lms.sexp carries the one adjudicated
entry (L1), cited to RG 476(f).
Mutation-tested: inverting RG 475(a)'s Sunday clause reddens 10
existing Rubrics_ef unit tests AND this new layer's own comparator,
independently, on a data source none of the other five layers touch.
Reverted after confirming.
No lib/ changes. day/readings/rubrics output re-confirmed byte-
identical (1583, 2026, 2038, 9999) after this task; all three gates
green (dune test, exhaustive sweep, make check).

The Latin Mass Society Ordo 2024-2025 for England and Wales (v2.21,
compiled by Peter Day-Milne) gives 9 August 2025 as "OUR LADY on SATURDAY
IV Cl W / V Mass of BVM / Commem of St Romanus M at Low Mass" -- no vigil
-- and 10 August as the 9th Sunday after Pentecost with St Laurence
commemorated. That is colitur's output on both days, field for field.
It is discriminating where the Ordo already in docs/research was not. This
edition lists six vigils as the day's office across its year, including the
Assumption's on 14 August 2025, and its footnotes discuss arranging a
diocesan feast around the Vigil of St Laurence in other years. Its absence
on 9 August 2025 is an application of the rule, not a data gap. The
extraordinaryform.org Ordo omits that vigil on every date it covers,
including 2027-08-09 where the clause says to keep it, which is why it
witnesses nothing here.
Also confirms the Vigil of the Assumption as II Cl violet, the RG 128
colour this project corrected from the bootstrap's White.
The clause's other shape -- feast transferred away, 2022/2033/2038/2044 --
remains unwitnessed; no accessible Ordo covers those years. Stated in the
note rather than left implied.

Replaces the withdrawn Ordo claim with a real one of a different kind.
O'Connell, The Celebration of Mass (4th ed., 1964) -- a rubrics commentary
contemporary with the 1960 Code, outside the Divinum Officium ->
missalemeum -> lectio lineage, already cited here for RG 128 -- states all
three of RG 33's triggers in English, the third included, verbatim in
substance with the Latin.
The same passage confirms vigil_feast_table's membership independently:
Christmas Eve and Pentecost I class and so outside the rule; Ascension,
Assumption, John the Baptist and Peter & Paul II class; St Lawrence the
sole III-class vigil. Five entries, the same five, same class split.
It confirms the RULE and the ENTITY LIST, not the 10 days -- O'Connell
publishes no day-by-day calendar. The distinction is stated in the note
rather than blurred, since blurring it is what the withdrawn Ordo
paragraph did.

C39 and the 2025 golden pin both claimed the published Ordo independently
confirms RG 33's third trigger, because it omits St Lawrence's vigil on
2025-08-09 where lectio and missalemeum keep it.
It does not. The Ordo omits that vigil on 2027-08-09 as well, where the
clause says to keep it (10 August is a Tuesday, the feast holds its day),
and 2026-08-09 is a Sunday where the rule's first trigger omits it anyway.
The 2024 date has no row. So the Ordo never shows St Lawrence's vigil on
any date it covers, and the 2025 agreement is a blanket gap coinciding with
the right answer, not evidence.
The rule itself is unaffected: it rests on RG 33's text, which admits no
latitude, and on lectio not evaluating the clause at all -- "RG 33" appears
nowhere in its production code, and the third trigger cannot emerge from
per-day rank comparison because it turns on what is observed the following
day. The divergence is architectural, not a disagreement about the rubric.
Recorded rather than deleted: the withdrawn claim is why this entry was
first written up as unusually well corroborated.
|
| |
|
|
|
|
|
| |
The note apportioned the entry's ten rows as seven commemoration-reduced
and three transferred, counting 2038-06-23 in both halves to make the
arithmetic work. It is six and four; the row count itself was always
right, and is pinned by the comparator.

RG 33 omits a II/III-class vigil in three cases: it falls on a Sunday, it
falls on a I-class feast, "vel si festum cui praemittitur in alium diem
transferri aut ad commemorationem reduci contingat". Only the first two
were built; the third was recorded in precedence_ef.ml as unimplemented on
the grounds that no witness existed in the shipped data. That reasoning was
wrong, and the rule fires on 1 744 days across 1583-9999.
Both halves of the clause reduce to one observable question -- is the feast
the OBSERVED office on the following day (RG 34 puts it there) -- so the
kernel asks it once per candidate, after place_transfers has settled the
year. No fixed point is needed: a vigil is a candidate only on its own day,
never on its feast's, so suppressing it cannot change what the next day
observes. Precedence.rules gains vigil_feast, which returns the slug of the
feast a vigil precedes; the kernel cannot infer that itself, because only
two of the five vigil/feast pairs share a slug stem.
Blast radius, measured pre-change binary vs HEAD over the whole domain and
classified: 1 744 days, three shapes, zero unexplained. 1 199 are the feast
reduced to a commemoration (10 August on a Sunday, St Lawrence); 478 and 67
are the feast transferred under RG 96 after the Sacred Heart or Corpus
Christi takes its day. The Assumption's and the Ascension's vigils never
qualify -- their I-class feasts always keep their own day.
Independently witnessed, which is unusual here. The published Ordo -- the
only witness outside the Divinum Officium -> missalemeum -> lectio lineage
-- omits St Lawrence's vigil on 2025-08-09, agreeing with colitur against
both engines. That date had been read earlier as an Ordo gap; the Ordo was
right, and correcting the misreading is what surfaced this clause. On
2027-08-09 the feast does keep its day and the Ordo omits a vigil colitur
correctly keeps, which is a genuine Ordo gap.
Allow-lists: C39 (lectio, 10 rows) and a 2038 oracle class citing the
register, the 2026-2027 window having no instance. The golden pin asserting
St Lawrence's vigil is violet moved 2025 -> 2027; its own comment had
reasoned about the vigil's weekday and missed that RG 33 also looks at the
feast's. Two new pins cover both shapes of the clause.
The vigil/feast table is built with Slug.of_string_exn: mutation testing
showed that of_string plus Result.to_option turns a typo into None, which
this hook's contract reads as "not a vigil", switching the rule off in
silence. Two tests assert the table against the shipped data in both
directions.

lectio adopted the last two Missal corrections colitur argued:
C14 3 -> 0 RG 96(a)/97/98. lectio resolved each impeded I-class feast's
transfer independently, so in 2008, 2035 and 2046 St Joseph and
the Annunciation both walked onto the Monday after Low Sunday
and Joseph, losing there, was observed on no day of those years
at all. It now resolves the year's transfers as a set: the
Annunciation takes the Monday as its sedes propria, Joseph the
Tuesday.
C15 7 -> 0 The Holy Family propers' own 13-January rubric, "sine
commemoratione Baptismatis D.N.I.C.". lectio kept the Baptism
as the observed office on all seven such years in 2005-2050.
Those were the last two BEHAVIOUR classes. What is left is C1 (138) and C6
(119), both pure slug vocabulary.
Measured across the whole fixture, applying only the season normalisation the
test already applies: 579 of 16801 days differ, and every one of them differs
on the SLUG ALONE. Zero days differ on season, rank, colour, Epistle or Gospel.
(The test's own norm_slug table already maps 322 of the 579; the 257 left are
C1 and C6. The field profile is the same either way.)
So the two engines now agree on every liturgically meaningful field on every
day of 2005-2050. The residue is what the two projects call things --
ef-christmas-2-friday against ef-time-after-epiphany-1-friday for the same day,
same Mass. Aligning it means renaming lectio's slugs, and those are keys: its
lectionary, clectio's generated tables and any user overlay are built on them.
Left as vocabulary rather than forced.
Fixture refreshed against lectio e713da2; 13 rows changed, colitur agrees with
all of them. 24 divergence classes at the start of this work, 2 now.

The ferias between Epiphany and the first Sunday after it repeat Epiphany's
own Mass in lectio now; they had been taking the Mass of the Sunday that
follows them.
C31 98 -> 0
C1 40 -> 138 grew, and changed character
C1 is now SLUG VOCABULARY ONLY, and its note says so. Season, rank, colour and
both citations agree with colitur on every day of the January window; what
differs is the identifier -- ef-christmas-2-thursday against
ef-time-after-epiphany-1-thursday for the same day with the same Mass. C6 is
the same shape.
That is 257 of the 267 remaining rows. Aligning the vocabularies would mean
renaming lectio's slugs, and those are keys: its own lectionary, clectio's
generated tables and any user overlay are built on them. Recorded as
vocabulary rather than closed, because the rows do differ -- just not in
anything a reader of either engine's output sees.
Measured for 2026: season, rank and colour agree on all 365 days; 14 days
differ and every one differs on the slug alone.
5 classes -> 4, agreement 98.4%.

lectio carries the readings of the nine Common-routed saints and of three more
that had proper Masses but no reading at all. Every day of 2005-2050 now
resolves a reading there; four days used to come back empty.
C38's own note said it could not close without lectio gaining a Commons
concept. The readings arrived instead of the abstraction, which was enough:
each Common resolves to one first/gospel pair for the saint that names it, so
a table plus assignment layer would have bought indirection and nothing else.
C20 14 -> 0
C38 70 -> 0
7 classes -> 5, 351 rows -> 267, agreement 97.9% -> 98.4%.

lectio gained the Passiontide week split and thirteen lectionary entries.
C23 230 -> 0 Holy Week's own six Masses
C32 99 -> 0
C35 60 -> 0 the first weeks after Epiphany and Pentecost (RG 299)
C33 46 -> 0 Corpus Christi
C34 46 -> 0 the Sacred Heart
C26 43 -> 0 Passion Tuesday
C19 7 -> 0 the Holy Family week-index residue
C1 75 -> 40
C31 63 -> 98 GREW
The Passiontide split is the one that carried most of this. efWeek had no
Passiontide case, so both weeks numbered 0 and every day of Holy Week took the
slug of its Passion-week namesake -- one set of readings for two weeks with
entirely different Masses. Good Friday was reading Passion Friday's.
C31 growing is the same bookkeeping as C1's earlier growth and is recorded in
its own note: C32 and C35 closed, and rows that carried several causes now
carry only this one. Nothing new disagrees.
17 classes -> 10, 1019 rows -> 488, agreement 93.9% -> 97.1%.
What remains is almost entirely NAMING rather than disagreement: C6 (119) is
colitur's ef-nativity-octave-day-N against lectio's ef-christmas-N-weekday on
days where both now read the same Mass, and C1 (40) is the same shape in the
January window.

lectio gained Rogation Monday and Tuesday (RG 87, violet under RG 128(d)) and
the Missal's own Mass for the weekdays within the Octave of the Nativity
("Diebus infra octavam Nativitatis Domini", Titus 3:4-7 / Luke 2:15-20).
C8 26 -> 0 CLOSED
C6 119 -> 119 narrowed: the cause halved, the count did not
C6 is worth reading carefully rather than skimming the number. Its rows no
longer differ on First_f or Gospel_f at all -- the two engines now read the
SAME Mass on 29-31 December, where lectio previously served the Sunday's. What
is left is Slug_f alone, colitur's ef-nativity-octave-day-N against lectio's
ef-christmas-N-weekday. That is vocabulary, not disagreement. The count did not
move because the entry's gate already admitted a Slug_f-only subset, which is
exactly the case where a row count is a misleading summary.
17 classes, 1019 rows, agreement 93.9%.

lectio built the votive Office of Our Lady on Saturday (RG 78) and then said
RG 309(a)'s own Mass for it. Both halves were needed: RG 78 keeps the office
and gives it white, RG 309(a) picks among the Missal's five seasonal
formularies. Fixing only the first leaves the day announcing Our Lady and
reading the feria's Mass -- the bug colitur itself shipped briefly and fixed
in its v0.3.0.
C17 439 -> 0 CLOSED -- the largest class between the two engines
C31 103 -> 63 Saturdays that carried both causes; only this one left
C35 69 -> 60 same
C1 35 -> 75 GREW
C1 growing is not a regression and is recorded as such in its own note: the
January Saturdays C17 used to absorb now differ only on the slug vocabulary
C1 already covers, so they land there instead. Rows moved between entries as
the larger cause was removed.
Also in this refresh, from the same session: weeks after Epiphany now count
from the first Sunday after it rather than from 6 January, which took C19
from 35 to 7 -- what remains there is the Holy Family interaction, a different
cause needing RG 17(b) in lectio.
19 classes -> 18, 1493 rows -> 1045, agreement 91.1% -> 93.8%.

lectio has taken three further corrections colitur argued from the Missal: the
twelve RG 124 colours (red is for Apostles, Evangelists and Martyrs, and
missalemeum had the rule inverted in both directions), Good Friday's black
under RG 128(b) with RG 132, and RG 72's Christmas Time boundary at 13 January
inclusive.
864 rows changed. Two classes closed outright and two moved:
C18 450 -> 0 the RG 124 colours -- the LARGEST single class in this file
C36 46 -> 0 Good Friday's colour
C1 159 -> 35 the season boundary stopped differing
C23 184 -> 230 Good Friday's rows fold back, the split no longer needed
C36 is closed rather than kept at zero because the split it represented has
dissolved: it existed only to hold Good Friday apart while its diff set had a
third member, and with the colour agreeing the rows are the exact pair C23 has
always gated on. Restoring 230 is not a regression, it is the number returning
to what it was before the split.
Cited classes 24 -> 19, divergent rows 2252 -> 1521, agreement 86.6% -> 90.9%.
The percentage is again the least interesting part. C18 alone was 450 days on
which the two engines agreed about nothing and now agree because both apply
RG 124 the same way round.

Every previous refresh of this fixture carried lectio's answers TO colitur,
because colitur's data was bootstrapped from lectio. This one carries
colitur's answers BACK. lectio has merged eight field corrections colitur
argued from the 1962 Missal: ubaldus and didacus promoted from commemoration
to III-class feast on the Missal's own calendarium, both August vigils
recoloured violet under RG 128, and both Ember Saturdays' readings, which
lectio had carrying St Thomas's and St Matthew's Masses respectively.
227 of the 16801 rows changed. Three cited classes went to zero and are
CLOSED and REMOVED, citations preserved in the register, the same discipline
C2-C5, C7, C9-C13, C21, C22 and C25 already record:
C27 40 -> 0 the Advent Ember Saturday's readings
C28 40 -> 0 the September Ember Saturday's readings
C37 77 -> 0 the two vigil colours
C37 is worth noting by name: its own note called the shared lineage "the
sharpest demonstration in the project", colitur and lectio and missalemeum all
carrying the same two wrong colours. Two of the three now carry the right one.
C38 NARROWED rather than closed, and the distinction matters. Its identity
half is gone -- lectio ranks both saints class-3 now -- but the same 70 rows
still differ on readings, because both saints take their Mass from a Common
and lectio has no Commons concept to resolve one. It is gated on
diffs = [First_f; Gospel_f] exactly, which is C18's shape. It cannot close
without lectio gaining a capability, which is a feature rather than a fix.
Net: 24 cited classes to 21, 2252 divergent rows to 2095, agreement 86.6% to
87.5%. The number that matters is not the percentage though -- it is that
those 227 days now agree BECAUSE BOTH ENGINES FOLLOW THE MISSAL, where before
they agreed because both inherited the same errors from Divinum Officium.
That is the failure mode CLAUDE.md's lineage note describes, resolved rather
than documented, for the first time in this project.

The first version of poland.ini marked three classes INFERRED because the
ordo's class column sits several lines below its own date row and the first
extraction pass did not reach it. All three are now read from the source:
Our Lady Queen of Poland class-1 (line 1114), St Stanislaus class-1 (1233),
Our Lady of Czestochowa class-1 (2398).
One of the three inferences was WRONG. Czestochowa was written class-2 as
"the conservative reading"; the ordo gives class-1. The mistake was treating
the ordo's "part." marker -- particular, proper to certain places rather than
universal in Poland -- as implying a lower rank. Those are different axes.
The extraction method was validated before being trusted, against two entries
whose class was already known from a clean single-line row: St Adalbert
class-1 and St Andrew Bobola class-2. It reproduced both.
Visible consequence, and it is correct: at class-1 Czestochowa no longer
commemorates St Zephyrinus, because RG 111(a) admits no ordinary
commemoration on a I-class day.
The ordo also names the particular sees each patron is proper to -- Stanislaus
for four archdioceses and three dioceses, Queen of Poland for Czestochowa and
Przemysl and the military ordinariate -- which is now recorded beside them,
and which reinforces the header's existing warning that a diocesan calendar
is not a national one.

Poland and the Benedictines, in the flat INI form, installed beside the
invented diocesan example.
poland.ini -- 17 entries from the Calendarium Perpetuum pro Dioecesium
Poloniae (1964), promulgated under Rubricarum instructum and applying to the
1962 Missal. Transcribed from a published Polish EF ordo that names that same
calendar, cross-checked against missalemeum's supplement page for the two
formularies 1964 added (13 and 15 July). Date, Latin name and class were read
from the source for every entry; three classes could not be recovered from
the PDF's column layout and are marked INFERRED where they appear, with the
reasoning. The header carries an edition warning that is a real trap here:
the Proprium Poloniae of 1921 and 1934 is still bound into many missals and
carries an outdated arrangement of dioceses and ranks. It is not this
calendar, and it is exactly the kind of plausible wrong-edition source that
has cost this project time before.
benedictine.ini -- two entries, and the comment explaining why is the point of
shipping it. Counted across the Norcia ordo: 86 "I cl.", 43 "II cl.", ZERO
"III cl." and ZERO "IV cl.", against 103 "Semidup." and ~96 "Dup.". The
monastic rite uses the Roman classes at the top and the older Duplex /
Semiduplex grades below, exactly where the Roman calendar has III and IV
class. colitur's rank vocabulary cannot express those, so most Benedictine
propers cannot be written here at all -- a mismatch of vocabularies between
related rites, not a gap in the data. Rather than invent a Duplex -> Class3
mapping the source never states, that file ships only what its ordo gives in
Roman terms and lists roughly two dozen excluded feasts BY NAME, so the
omission is visible instead of silent.
Both headers say plainly that they are examples and not authorities: they are
transcriptions from published ordines, none of the five test layers can vouch
for either, and both should be checked against the reader's own ordo. The
cram test asserts only what we control -- that they parse, convert and apply
-- and says so.
They also demonstrate the precedence engine on real data: the Benedictine
Transitus is I class and takes 21 March with the Lenten feria commemorated,
and Maurus is II class and takes 15 January with Paul the First Hermit
commemorated.

Both carried rank Class3 with status Commemoration_only, bootstrapped from
lectio, which inherits it from missalemeum, which is generated from Divinum
Officium. The Missal's own universal calendarium ranks both "III classis"
outright, with no commemoration rubric: "S. Ubaldi Ep. et Conf., III classis"
(16 May) and "S. Didaci Conf., III classis" (13 November), corroborated in
the second scan and in a published 1962 Ordo.
Universal by construction, not by assumption: the calendarium carries no "pro
aliquibus locis" marker in its 573 lines while the wider Missal carries 79 of
them elsewhere. Each saint also has his own Mass entry in the Proprium, which
a bare commemoration never has -- a commemoration carries an oration only.
Found by auditing ALL 290 fixed-date entries against that calendarium, day by
day, anchored on the Roman calends column because the arabic day column is
OCR-wrecked and the dominical-letter column vanishes in some months. These
two were the only status defects in the whole file. The 15 days the automated
pass could not cover were read by hand and all agree.
Neither needed a proper authored: each takes its Mass from a Common with only
its own Oratio proper, per its own rubric at its own date. ubaldus shares
patrick's Common exactly. didacus needed one newly transcribed --
common-of-a-confessor-not-a-bishop-2, the "Altera Missa" Iustus, 1 Cor 4:9-14
and Luke 12:32-34, read independently in both scans, which agree, so the
page-image third reading this file's method requires on disagreement was not
triggered.
Blast radius, full 1583-9999 sweep, every day classified: 13 036. That is
5 564 ubaldus observed, 7 196 didacus observed, and 276 where the Ascension
Vigil still wins on 16 May but its single RG 111(c) slot passes from
rogation-wednesday to ubaldus -- correct and already pinned, since the
Rogation days are the MINOR Litanies and so an ordinary commemoration, which
RG 113's table order ranks below a III-class feast. Cited as C38 (70 rows)
and M30 (3); C8, C17 and M18 shrink accordingly, each with the reason
recorded rather than the count silently adjusted.

RG 128, transcribed in the rules register since 2026-08-11, gives violet to
"vigils of II and III class outside Paschaltide". The Vigil of the Assumption
(14 August, II class) carried White and the Vigil of St Lawrence (9 August,
III class) carried Red. Both are outside Paschaltide, so both are violet. The
Ascension's vigil is untouched: it is the one II-class vigil inside
Paschaltide and was already correctly white.
The rule had been sitting in the register, disagreeing with the shipped data,
since before the data was bootstrapped. It was invisible because colitur,
lectio and missalemeum all carried the same two wrong colours -- colitur was
bootstrapped from lectio, lectio's ini is generated from missalemeum, and
missalemeum uses Divinum Officium's data files. Three sources agreeing is one
source counted three times, and the differential and the oracle both went
green on the shared error. It surfaced only against witnesses outside that
tree: a published 1962 Ordo flagged the Assumption's, and O'Connell, The
Celebration of Mass 4th ed. (1964), section 4(c) and footnote 169, gave the
general rule and with it St Lawrence's, which the Ordo omits entirely.
Two golden pins added, in years where each vigil is actually observed rather
than impeded. The divergence this creates against every DO-lineage source is
cited in both allow-lists: C37 (lectio, 77 rows -- 92 possible minus 15 where
the vigil falls on a Sunday) and M29 (missalemeum, 3 rows in 2026-2027 and 2
in each of 2035 and 2038). Both gated on the exact slugs or dates and on
colour alone, so any other divergence on those days would still surface.
Also recorded, no code change: rose on Gaudete and Laetare stays. RG 131 is
permissive ("adhiberi possunt") and the Ordo prints violet, so the colour
field carries a permission rather than a requirement on those two Sundays a
year -- a decided position now, not an unexamined one.

RG 128(b)'s own exception list, transcribed in the rules register and
primary-source-verified since Task 16, excepts "Actione liturgica feria VI
in Passione et Morte Domini usque ad Communionem exclusive" from the violet
that otherwise runs from Septuagesima to the Easter Vigil. RG 132 assigns
black there. The register recorded this as an acknowledged gap rather than a
disputed reading -- the code comment beside the Holy Thursday exception says
so in as many words -- and it is closed here.
Found by two witnesses outside the Divinum Officium lineage that colitur,
lectio and missalemeum all share: O'Connell, The Celebration of Mass, 4th ed.
(1964), revised throughout to the Codex Rubricarum (1960) and the 1962
Missal, and a published 1962 Ordo. Both say black. So does missalemeum's own
colour set, which orders the day "bv".
The rubric is per-action ("usque ad Communionem exclusive") and the model
emits one colour per day; black is the day's principal one, the same
acknowledged limit RG 126's Palm Sunday blessing already carries.
Blast radius: one day per year, colour only, across the whole 1583-9999
domain. Two golden pins re-pinned. Good Friday's 46 differential rows leave
C23 for a new C36 gated on the exact triple [First_f; Gospel_f; Colour_f],
so C23's own exact-pair gate still means what its note says for its
remaining four days: 184 + 46 = 230, no residue, both counts from the
comparator rather than hand-counted.

C6 was closed by the Nativity-Octave fix rather than by argument. Its own
note had already split the 138 rows into 119 weekday rows, where it
recorded colitur's citation as confirmed correct and said verdict colitur
would be accurate for that subset alone, and 19 Sunday rows where colitur
emitted the weekday formulary against RG 69 and was plainly wrong -- a
Temporal_ef defect the entry deliberately left out of its own scope. That
defect is fixed, and the count fell 138 to 119: exactly the population
the note had enumerated by date. Verdict open becomes colitur on
reasoning already written there.
M26 closed on a positive argument, not an absence. Both its other shapes
are now built -- the BVM Saturday Mass selection and Trinity's week --
leaving Christ the King's week. RG 299's rule has an escape clause and
the escape requires an assigned proper Mass; none is assigned for that
week, checked at the source, unlike Trinity's week which prints one and
unlike Holy Name and Holy Family which each carry a ferial rubric. That
absence is not a research gap, it is the condition that triggers RG 299's
default -- and by the default the ferias say the preceding Sunday's Mass,
which on this week is Christ the King's own.
The limit is stated in the entry rather than glossed: this reads a
printed silence as the default rather than as an oversight, which the
text cannot distinguish. It is the same reading applied everywhere else
RG 299 governs, and applying it inconsistently here to match an oracle
already adjudicated wrong six times would be the worse error.
No entry in either allow-list is now verdict open or verdict missalemeum.
The only non-colitur entries are M15 and M18, both unresolvable, and both
are comparator limits rather than calendar disagreements: a
temporal-origin celebration carries no English name, so its identity
cannot be matched even where both streams plainly mean the same thing.

M11 was the one entry in the missalemeum allow-list adjudicated against
colitur, and it was right to be. The calendarium directs "Com. octavae
Nativitatis" under each of 26, 27 and 28 December (LT.txt:5454-5459) and
RG 109(c) makes a commemoration of the days within the Octave privileged.
colitur emitted none.
The cause was a reasoning error stated in Temporal_ef's own comment:
"26-28 Dec are Stephen, John and the Innocents, hence sanctoral". Their
office is sanctoral -- those II-class feasts win the day -- but they
remain days WITHIN the Octave (RG 67, "Dies infra octavam sunt II
classis"), and colitur built them as generic Class4 ferias. With no
octave-day candidate there was nothing for the feast to be commemorated
over. Building days 2-4 exactly as days 5-7 always were makes the
commemoration fall out of the existing machinery rather than needing a
special case: the feast wins on rank, the octave day loses, RG 109(c)
privileges it, RG 111(c)'s single slot goes to it.
A second, independent defect surfaced while fixing it. The octave-day
branch covered 29-31 December unconditionally, so a Sunday falling there
got a feria identity -- where RG 69 says a Sunday occurring 26-31
December SEMPER keeps its own office and commemorates the feast.
Confirmed against the oracle rather than argued: missalemeum shows
"Sunday in the Octave of Christmas" on 2035-12-30, a Sunday, where
colitur showed a feria. Both named and anchors now exclude Sundays;
anchors had asserted the octave slugs unconditionally and was wrong the
same way.
Blast radius, full sweep against the pre-change binary: 25251 days, every
one 26-31 December, exactly two shapes, zero unclassified -- 21653
carrying an octave-day slug and 3598 that are all Sundays, the RG 69
correction.
Allow-lists: M11 closed and removed. C6 narrowed 138 to 119, nineteen of
its days having changed temporal identity rather than verdict. M15
widened 18 to 22 -- both streams now commemorate the octave, but the
candidate is temporal-origin and carries no English name to match against
missalemeum's own, this entry's documented limit on four more dates.
Stated rather than glossed: this trades a substantive divergence, colitur
omitting a commemoration the Missal directs, for a comparator limit, the
commemoration existing but not being name-matchable. That is a real
improvement, but what the oracle now proves is that both streams
commemorate something on those days; the identity rests on the rubric and
the calendarium.

`--overlay` shipped last week with nothing to point at. The only example
was a test fixture, explicitly labelled invented and living where no user
would find it, so "colitur supports local calendars" was true but
undemonstrated.
data/ef/examples/diocesan-example.sexp is installed to
<prefix>/share/colitur/examples/ and is runnable documentation: every
celebration in it is invented, with example- slugs that cannot collide,
and its header explains the four directives, the three date shapes, and
the field vocabularies before showing any of them.
It demonstrates the range deliberately rather than the minimum: a
fixed-date local patron with its own propers; a movable dedication on the
first Sunday of October, I class because a church's own dedication
anniversary is I class in that church and at III it would lose to the
Sunday every year; an Easter-relative commemoration; an Edit raising a
universal feast for local use; and a Suppress shown commented out,
because suppressing a universal feast is a real liturgical act and an
example should not invite it casually.
Two things the header says plainly, since this is the one file that lets
someone change what colitur computes: an overlay is applied ON TOP of the
shipped calendar and never instead of it, and an overlay is applied, NOT
validated -- the five test layers assert things about the shipped data
and cannot vouch for a user's file.
A test asserts it loads against the real EF rank vocabulary, still
demonstrates at least four directives, and applies with NO diagnostics.
The last matters most: a directive naming a slug the universal calendar
lacks would warn, and an example that warns teaches the wrong lesson. It
deliberately does not pin which days it produces -- those celebrations
are invented, and pinning their dates would make an illustrative file
behave like calendar data.

Two open questions closed, both by looking rather than reasoning.
M13 listed three possibilities for 19 March 2027 and stayed open because
none was confirmed. The live one was (b): a rubric at St Joseph's own
Proprium Sanctorum entry overriding the general table, "the same shape as
the Annunciation's own Attamen clause", its text simply not yet found. It
was looked for directly. Joseph's entry runs from its heading straight
into the Introit with no rubric of any kind -- and the analogue does not
exist where the note placed it either: the Annunciation's entry does the
same. That exception lives in RG 96, a general rubric about transferring
an impeded I-class feast, not in its propers, so there is no precedent
for a propers-level override at all.
With (b) eliminated and (c) still unsupported, (a) stands: RG 91 ranks a
I-class feast above a III-class Passiontide feria, Joseph is not impeded
so RG 96 never engages, and colitur observes him. Recorded with its
limit, because this is elimination and not proof: the specific hypothesis
named is false, which is weaker than showing no rubric anywhere says
otherwise.
Separately, the note that Mass I of the BVM Saturday needed an
Advent-Saturday oracle year to corroborate it is answered: there is no
such year and cannot be. Advent has no IV-class ferias -- Class2 from 17
December, Class3 before -- and RG 78 requires a IV-class feria. Zero
IV-class Advent Saturdays across 2000-2100. Its single witness is not a
gap in the research but the only evidence obtainable. The branch is kept:
the Missal does print the Mass for Advent, RG 309's subject being Masses
that may be celebrated as votive, and an overlay producing such a day
would otherwise fall through silently.
Register: sections 6.13 addendum and 6.14.
