RG 78's office has been built since ef-bvm-saturday: an otherwise
unoccupied IV-class Saturday is de sancta Maria in sabbato, white, IV
class. The Mass stayed the feria's, so the day observed Our Lady and then
read Colossians on the parable of the weeds. That is M26 shape 1.
RG 309(a) is the rule -- the Masses the Missal assigns "iuxta temporum
diversitatem" -- and it prints five, each under its own season heading.
All ten citations are transcribed from the scans with line numbers in the
source. Masses II-V were confirmed twice, against the scan and against a
live missalemeum capture of 2038 which names them and agrees on both
readings. Mass I rests on the scan alone: no oracle year to hand has an
Advent Saturday carrying this office. One witness where the others have
two, and the code says so rather than blurring it.
The mapping looked like the hard part and dissolved. The Missal's ranges
are cut by civil dates and movable feasts, not by this rite's seasons --
II ends mid-season at the Purification, III spans four seasons. But
measured against what a IV-class Saturday can actually be, it reduces to
a seasonal mapping plus one date test at 2/3 February, with no Easter
arithmetic at all: III's end to IV's start leaves the Triduum unassigned,
unreachable because Holy Saturday is I class; IV's end to V's start
leaves Pentecost week unassigned, also unreachable because that week's
Saturday is an Ember Saturday. Time after Pentecost then begins exactly
at Trinity, exactly where Mass V begins. Both gaps verified by sweep --
zero IV-class Saturdays in either across 2000-2059 -- not inferred.
The office is identified structurally, never off the slug, which it
deliberately shares with the ordinary feria: subject Bvm, IV class,
Saturday.
Blast radius: 87611 reading rows over the full domain, every one a
Saturday.
Allow-lists: M26 27 to 6, shape 1 gone, leaving only the Christ-the-King
residue argued in colitur's favour last commit. The 2038 suite's
BVM-SATURDAY-MASS class is removed rather than zeroed -- an id with no
rows must not be declared. M18 355 to 376. C17 widened 397 to 445,
taking its own Saturdays back from C1, C19 and C25, since one cause
should not be filed under two ids; C31 89 to 103; C25 closed at 0 rows,
its Holy-Name-week Saturdays now answered before step 3 is reached.
Three unit tests pinned the old behaviour and are corrected rather than
re-pinned: two asserted the day "keeps its ferial Mass", which was the
honest thing to assert while this was unimplemented. The third still
tests what it always did -- that step 4 refuses a temporal office -- and
only what answers instead has changed.

Date_spec carried one variant, Fixed(month, day), and its own header said
Sunday- and Easter-relative forms would arrive with the OF sanctoral. They
arrive early because two things needed them at once: a user-supplied
overlay carrying a local movable feast had no way to express "the first
Sunday of October", and Rogation Wednesday's commemoration has been
recorded as architecturally blocked since 2026-08-13.
That blockage turns out to have been a premise, not a fact. The register
concluded the Rogation "is not Commemoration_only sanctoral data by
nature... it needs a genuinely THIRD kind of thing this architecture has
no name for" -- but the reasoning rested on there being "no civil (month,
day) pair to anchor a Fixed entry to". That is a statement about
Date_spec's expressiveness. With Easter_offset the entity is ordinary
sanctoral data, the identical shape Add major-litanies already ships,
differing only in how the date is written. No third channel was needed.
The register is corrected rather than left contradicting the code.
Two variants: Easter_offset of int, and Nth_weekday of {month; nth;
weekday} with negative nth counting from the end. Fixed's sexp
representation is untouched, so all 327 sanctoral entries and the whole
overlay parse unchanged. Both are re-validated in t_of_sexp through their
smart constructors, extending the idiom Fixed already used -- the failure
that guards against is invisible, a spec deserialising into something
that silently never resolves and a celebration vanishing with no
diagnostic.
Easter is supplied by the rite, not computed in the kernel. Computus
ships Gregorian and Julian both, and picking one here would hard-code a
Roman assumption into rite-agnostic code and be silently wrong for a
Julian-reckoning rite. Rite.t gains an easter field; Rite_ef supplies the
Gregorian one.
Layer keeps a split index. Fixed entries stay in the year-independent
(month, day) table, which preserves the fast path and the "30 November
counted twice in a 371-day span" behaviour validate.mli documents for St
Andrew. Movable entries have no year-independent key by construction --
the same spec lands on a different (month, day) each year -- so they
resolve per civil year into a rata-die table. index_by_date is removed
rather than kept as an alias: two ways to index a layer, one of which
silently ignores movable entries, is the trap this change exists to
avoid.
Two domain-edge defects, both found by the suite rather than reasoning. A
liturgical year is Advent-anchored, so resolving civil year y names y +/-
1, and at the edges those are 1582 and 10000, which Computus correctly
refuses by raising. The ceiling surfaced through the domain-ceiling test,
the floor through `colitur day 1583` failing outright. Fixed once, in
Layer.index, the single point that calls the rite's easter -- a clamp
repeated per caller would have been two places to get wrong a third time.
Rogation Wednesday: RG 87 assigns the Litaniae minores to the Monday,
Tuesday AND Wednesday before Ascension (scan1:691); colitur built the
first two from the start and never the third. RG 88 keeps it out of the
Office, so the Ascension Vigil remains observed. RG 89 routes it through
the Major Litanies' rules, but RG 109's closed list names only maiores,
so by RG 107 it is an ORDINARY commemoration -- confirmed in the output,
not assumed. Name from the Missal's own "feria IV" (scan1:20495-20497),
violet to match the Monday and Tuesday offices.
Blast radius, full 1583-9999 sweep against the pre-change binary: 2257
days, every one the same shape, zero unclassified, line counts equal both
sides. The complement is the informative half -- in the other 6160 years
the Rogation does not appear at all, because RG 111 admits one
commemoration on a II-class day and an impeded feast takes it under RG
113, a Commemoration_only candidate having no row in RG 91's table. Both
shapes are pinned.
Allow-lists unmoved: layer 3 compares no commemorations and is blind by
construction, and layer 4's 2026-2027 window has a competing feast on
both Wednesdays, so the Rogation is capped out in exactly the years the
oracle can see. C8 is unchanged, asserted by its own count pin.
Not built: Sunday-relative specs, which nothing needs yet, and the
--overlay plumbing that would let a user actually supply a local movable
feast. Nth_weekday therefore ships with synthetic and property coverage
only; inventing a shipped entry to exercise it would be fabricating
calendar data.

Layers 2 and 5 for the reading citations, which until now had coverage
from layers 3 and 4 only -- both oracle-bounded, at 2050 and 2027.
test_validate.ml said so in its own words ("No fixture here exercises
citations") and test_golden.ml's describe pinned twelve fields, none of
them a citation. 358 tests -> 369, and 370 under the sweep.
Layer 2 as two Validate checks rather than standalone QCheck properties,
so they ride the existing prop_invariants and the exhaustive sweep
instead of duplicating that machinery. "citations" asserts a day's parts,
sorted, are exactly [First; Gospel] -- one condition carrying three
invariants: zero or two but never one, nothing outside First and Gospel
since the chants are deliberately unbuilt, and no part twice, which a
bare cardinality test would miss. "citations-unresolved" is the separate
coverage half: the chain fell through every step. Both are gated on the
rite producing some citation somewhere, so a rite whose lectionary is not
built is held to neither and the synthetic fixtures stay unaffected.
The result over the whole domain: every day of every liturgical year
1583-9999 resolves exactly one Epistle and one Gospel. Mutation-proved
live rather than merely silent -- treating a well-formed pair as
malformed reddens the suite with real days showing [first,gospel].
citations-unresolved has no live witness at all, which is why
test_validate.ml gains five fixtures driving both checks through a new
?readings override, including the gate itself.
Layer 5 as six pins, one per chain step, so a regression names the step
that broke. Every literal was read out of the scans before being
compared with colitur, per that file's standing rule; scan lines are in
each pin's comment. Two of the six cover step 4, and the plan's own dates
for steps 1 and 4 were wrong: 2030-01-13 is a temporal day (Holy Family
on the generic Sunday slug) and would not have exercised step 1, while
2038-03-08 is John of God, who has a full proper Mass and never routes
through a Common -- so he becomes the step-1 pin instead.
A separate formatter rather than widening describe: widening would
invalidate all thirty existing literals at once and the only practical
way back would be pasting in whatever colitur printed, which is what the
file's header forbids. Restoring them honestly means hand-verifying
thirty more Masses against the scans, a task of its own. Stated rather
than hidden, and defensible because layer 2 now checks the shape of
every day in every year, which is the breadth that widening would have
bought.
Two pins earned their keep immediately. Lent I Monday failed on "Ezek"
against colitur's "Ezech" -- notation only, and colitur matches the
Missal's own abbreviation; layer 3 normalises this away and cannot see
it. The displaced-Sunday feria pins M26 shape 2(b)'s known-wrong
walkback deliberately, labelled as such so a future fix fails loudly,
and established two things M26 had not recorded: both parts come from
the displacing feast, not only the Gospel it cites, and the reference
carries a stray trailing period inherited through the bootstrap.
Blast radius: zero. The CLI never calls Validate, no data file changed,
and 20 years spanning 1583-9998 produce 7301 byte-identical lines
between the pre-change binary and HEAD.
Step 4's blind spot is now measured rather than argued. Corrupting the
Common of Non-Virgins I's Epistle leaves layer 3 (16801 days) and layer
4 (730 days) both green, reddening only one unit test and one new pin.
Both step-4 pins matched the scans on the first attempt -- the first
independent confirmation that route has ever had. It narrows the gap
without closing it: two of five Common-routed saints are witnessed,
isidore-of-seville is not, and gregory-the-great and patrick are
unreachable in any year 2005-2050.
Register: section 6.7 addendum. validate.mli documents both new labels;
liturgical_day.mli's "always empty until Plan 4" was outlived by the
lectionary and is corrected.

Two Critical findings, both real: Holy Week (including the entire Sacred
Triduum) was reading Passion Week's Masses -- the original colitur_keys
widened lectio's single, conflated ini section into both weeks instead of
Passion week alone. Narrowed to Passion week only; Holy Week's own four
cleanest days (Monday, Tuesday, Thursday, Saturday) are hand-authored
directly from the Missal, verified twice against both scans (C23); Holy
Wednesday and Good Friday are genuinely multi-lesson liturgies with no
single Epistle slot and are deliberately left unanswered, not guessed (C24).
The Lenten Ember days were still dead keys: Temporal_ef computes
ef-lent-ember-{wed,fri,sat}, lectio's ini names the same data
ef-lent-1-{wednesday,friday,saturday}, and colitur_keys never translated
it -- both engines independently fell through to the same wrong ferial
answer, so even the differential stayed green (C22, a genuine lectio bug
recorded for upstream). Fixed the instance and the class: colitur_keys
gained the rename, and tools/bootstrap_lectionary.ml gained
assert_reachable, sweeping Rite_ef.Temporal_ef.temporal at generation time
so a translation table entry naming a slug colitur never computes dies
loudly instead of shipping silently, plus an informational log of every
real slug with no entry at all.
C21 ("colitur's step 3 cannot reach a correct answer for the fixed
Christmastide slugs") is retired, superseded rather than merely patched:
the Nativity-Octave days now have their own direct Missal formulary
(Tit. 3,4-7/Luc. 2,15-20, "Diebus infra octavam Nativitatis Domini"),
resolved at step 2, not step 3 at all. That surfaced a real RG 69 gap
underneath it: a Sunday landing 26-31 December should keep its own Office,
not the fixed weekday placeholder, which Temporal_ef does not currently
distinguish. C6's verdict is re-opened (open, not colitur) for the 19 of
its 138 rows where this applies directly, and a new entry C25 (57 rows)
records the same gap propagating one hop further through step 3 into Holy
Name week. Both are out of this task's own scope -- a behaviour change to
a shared, multi-round-reviewed kernel-adjacent function -- and recorded,
not fixed, per the coordinator's own instruction.
C6's own note is rewritten in full rather than layered with another
correction; C18's stale trailing count is fixed to match its own pin; the
Vigil-misapplication risk flagged as a Minor closed itself once the
Nativity-Octave fix landed, confirmed by inspection rather than assumed.
dune test: 358/358. COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force: 359/359.

Review re-verified all fifteen saints and all seven formularies against both
printings and found zero citation discrepancies, confirming the Gabriel
printing error and all three proper/Common reversals; the reordering was
adjudicated sound. Two Important findings, both about the guard rather than
the data.
IMPORTANT 1 -- the guard had no test, and a comment claimed it did.
`test_step4_never_diverts_a_temporal_office` asserted 2026-07-04 keeps its
ferial Mass and its comment claimed to "pin it behaviourally". It did not:
no shipped assignment names a temporal slug, so the guard is a NO-OP on
shipped data and that test passes with the guard removed. The reviewer
proved it by forcing `sanctoral_office = true` -- all 357 tests stayed
green. That mattered more than an ordinary missing test: the guard is the
structural claim the whole reordering argument leans on, and on a task with
no oracle the tests are the entire safety net.
Fixed by exposing `Commons.of_tables` (already present internally; it
applies exactly `load`'s validation, so a synthetic table is a well-formed
table with a WRONG assignment rather than malformed data the loader would
reject before the guard is reached -- and it is the constructor a future
diocesan overlay needs anyway), adding `day_with ~commons` beside `day`, and
writing test_step4_guard_refuses_a_common_assigned_to_a_ferial_slug: a
synthetic Commons assigning the Common of Abbots to
`ef-time-after-pentecost-5-saturday`, a really-observed ferial slug,
asserting 2026-07-04 still says its ferial Mass. Two checks, the first
making the second mean something -- it asserts the hostile assignment IS
present and resolvable, so the ferial Mass wins because the GUARD refused it
and not because the lookup missed. Mutation-verified: with the guard
disabled exactly one test fails, this one; before this round that mutation
reddened nothing. The old test is renamed
test_step4_leaves_a_temporal_office_alone_on_shipped_data and its comment
corrected to say it does not pin the guard.
IMPORTANT 2 -- the guard cited an authority that does not say what was
claimed. The comment said "[Validate] already asserts slug uniqueness per
liturgical year, so a sanctoral feast can never collide with a temporal
slug". validate.ml's check maps over `Temporal.office` slugs ONLY, compared
to each other across the days of one year; it says nothing about
cross-stream collision. An assumption was promoted to an asserted invariant
-- the exact defect class this project's citation discipline exists to
catch. Rewritten to state it as an assumption (no sanctoral slug carries the
`ef-` prefix every temporal slug does; 0 of 327 today), to quote the real
authority verbatim (validate.ml's own note that this "is the same assumption
the rest of this codebase already leans on"), to carry a CORRECTED marker
naming the wrong citation so it is not re-derived, and to record the failure
mode if it ever broke: benign and one-directional -- a colliding saint is
denied his Common and falls through to steps 2/3, i.e. to exactly the answer
the unguarded chain would have given him. No day gains a reading it should
not have.
MINOR -- the previous commit body led with "Blast radius, measured ... ZERO
differing lines", which is true but oversold: the CLI prints no citations, so
that sweep is STRUCTURALLY INCAPABLE of observing the reorder or any citation
value. It is a valid negative control for the sanctoral `Edit` overlay and
nothing else. The evidence for the reorder is mutation 1 (relegating step 4
to last reddens exactly the four step-4 pins) plus those pins' own explicit
expected values -- not the sweep. Correcting the record here.
MINOR -- test_commons_load_rejects_bad_data wrote four FIXED-name files into
the temp dir and removed none, colliding across concurrent runs. Replaced
with a local `with_temp_file` copied from test_lectionary.ml's own
(`Filename.temp_file` + `Fun.protect ~finally`); the four labels moved into
the assertion messages where they belonged. Verified zero leftovers after a
full run.
MINOR -- added the sharper argument for the reorder, which makes the
deviation obviously right rather than merely well-evidenced, and it now LEADS
the branch comment as warrant (1), with the Missal citation demoted to a
corroborating warrant (2): step 4 is STEP 1'S CONTINUATION. Step 1 already
runs the observed office's own proper ahead of steps 2 and 3; step 4 is that
same rule for the saints whose readings the Missal keeps in a Common instead
of printing on the celebration. Placing it last would have made the chain
internally inconsistent with code that already existed -- St Joseph beating a
competing temporal entry because his readings sit on his Celebration.t, and
St Vincent Ferrer losing to one because his sit one indirection away. Nothing
in the rubrics draws that distinction; it is an artefact of where colitur
stores the data. So the plan's ordering did not merely disagree with the
data, it contradicted step 1.
358 tests green (357 before), 359 with the exhaustive sweep.

Fifteen class-3 saints had no readings anywhere in colitur -- the 6 March -
5 April cluster whose RANKS lectio's generator fix of 2026-08-12 restored
without backfilling readings, and lectio has no Commons concept to have
backfilled them from. They are exactly the fifteen `status Feast` entries in
data/ef/sanctoral.sexp carrying `(citations ())`.
The Missal splits them eight/seven, and NOT as the plan predicted. It
expected propers for Benedict, Patrick, Thomas Aquinas and Gregory the
Great; only Thomas Aquinas has one. Benedict ("Missa Os iusti, de Communi
Abbatum"), Patrick ("Missa Statuit, de Communi Confessoris Pontificis I
loco") and Gregory the Great ("Missa Si diligis me, de Communi unius aut
plurium Summorum Pontificum") are all sent to a Common, with only Oratio,
Secreta and Postcommunio printed at the date. All three reversals verified
on the page images (pp. 488, 492) as well as in both OCR text layers.
PROPERS (data/ef/adjustments.sexp, `Edit ... Set_citation`):
thomas-aquinas 7 Mar Sap 7:7-14 / Mt 5:13-19
john-of-god 8 Mar Eccli 31:8-11 / Mt 22:34-46

vincent-ferrer 5 Apr Conf. non Pont. I Eccli 31:8-11 / Luc 12:35-40
Every value read in three independent places -- both OCR text layers (two
DIFFERENT printings, whose Commune Sanctorum pagination differs by 1-2, so
the data keys on heading plus Mass incipit and never on the bracketed page
number) and the rendered page images. That caught a genuine typographical
error in one printing: it gives St Gabriel's Gospel as "Luc. 2, 26-38" (on
the page image, so not an OCR artefact). Luke 1:26-38 is settled by the
other printing, by the pericope text in both, and by the SAME edition citing
the identical pericope correctly two pages later at the Annunciation.
Step 4 EXECUTES SECOND (order 1, 4, 2, 3), not last as the plan sketched.
Measured: every day on which one of the fifteen is actually the observed
office already has a non-empty step-2 or step-3 answer waiting, so a step 4
placed after the ferial fallback is unreachable on every date in 1583-9999 --
and wrong where it would fire (2038-03-06 would emit Septuagesima II
Saturday's Mass on a day whose office is Sts Perpetua and Felicity). Step 4
is also the only step in the chain with a direct primary-source warrant: the
Missal names the Mass at each such saint's own date, while steps 2 and 3 rest
only on lectio's observed behaviour. Guarded so it can never divert a day
whose observed office IS its temporal office -- ferias, Sundays, the Triduum
and the RG 78 Saturday Office of the BVM (which deliberately shares the
ferial slug) are structurally excluded. Step NUMBERS are unchanged so every
"step 3" already written down still names the same branch.
The Commons are caller-supplied, like the lectionary: `Rite_ef.context` gains
a REQUIRED `~commons`, not an optional one -- a silently-defaulted empty
table would give a rite whose class-3 saints quietly lose their Mass, and
nothing in layers 3-5 compares citations, so that loss would be invisible.
`Commons.load` rejects the four defects indistinguishable downstream from
"this saint has no Common": duplicate common id, duplicate assignment, empty
formulary, assignment naming a common that does not exist.
KNOWN LIMITS, recorded rather than papered over. There is no oracle: lectio
has no readings for these feasts and missalemeum's 2026-2027 window never
observes one of the fifteen. Eight of the fifteen are NEVER the observed
office anywhere in the domain (10-28 March always falls to a Lenten or
Passiontide feria that outranks a III-class feast), so they have no
end-to-end witness and are covered by dedicated table tests instead. The
Commune Sanctorum's own opening rubric permits any Epistle or Gospel of a
Common in any Mass of that Common unless one is assigned, so what is emitted
is the reading PRINTED WITH the named formulary, not the only lawful one;
labelled alternatives (e.g. the widow's Epistle 1 Tim 5:3-10, squarely
available to St Frances of Rome) are noted in the data and deliberately not
encoded. The BVM Common is NOT authored: the RG 78 Saturday Office shares the
ordinary ferial slug, so assigning a Common to it would hand the BVM Mass to
every feria sharing that slug; routing it needs a subject-keyed lookup and a
season-keyed choice among the Missal's five "Missae de sancta Maria in
sabbato" -- new behaviour, not new data. It currently emits its feria's Mass,
now pinned as such.
Blast radius, measured (git archive HEAD binary vs HEAD, full 1583-9999
`colitur day` sweep, diffed): ZERO differing lines, 3 074 246 lines each
side, byte-identical -- the CLI prints no citations, so this change is
invisible to layers 2-5 by construction, and the sanctoral overlay perturbed
nothing else.
357 tests green (344 before), 358 with the exhaustive sweep. Mutation-tested
six ways, all reverted after confirming: relegating step 4 to last reddens
exactly the four step-4 pins and nothing else; corrupting a Common's citation,
dropping an assignment, dropping a proper Edit, and corrupting either an
unreachable proper or an unreachable Common each redden their own pins. The
load-bearing assertion is stated over the loaded layer rather than a
hard-coded list: every sanctoral entry that can ever BE the observed office
now has either a proper or an assigned Common -- fifteen failures before,
zero after, and a future re-bootstrap adding a readingless class-3 feast
fails there instead of silently emitting its feria's Mass.

ba0adba's own wrong commit body
Three Important findings, all traceable to the task-5 brief rather than
the implementation itself; all confirmed against the real data and the
real resolver before fixing, not taken on trust.
1. test_step3_uses_temporal_not_observed (2028-12-26) did not exercise
step 3 at all: 26 December is always Stephen, a real sanctoral entry
with its own citations, so that date resolves entirely at step 1.
Its justifying comment was also wrong -- 24 December's TEMPORAL slug
is ef-nativity-vigil, IDENTICAL to its observed slug (Temporal_ef.named
hard-codes the Vigil for that date ahead of any Sunday computation),
so there was never a temporal/observed split on that date to exploit.
Replaced with 2025-02-03: 2 February 2025 (Sunday) is observed as the
Purification (own citations Mal 3:1-4 / Luke 2:22-32) but its TEMPORAL
identity is ef-time-after-epiphany-sunday-4 (Rom 13:8-10 / Matt
8:23-27, a different lectionary entry); 3 February has no proper of
its own and reaches step 3, which must return the Sunday's TEMPORAL
reading, not the Purification's. Verified against
data/ef/sanctoral.sexp and data/ef/lectionary.sexp directly.
2. The termination-argument comment in lectionary_ef.ml (and its echo in
lectionary_ef.mli) claimed an unguarded Sunday would loop. It would
not: readings is not recursive -- step 3's fallback is one flat
Lectionary.find, never a re-entrant call into readings -- so an
unguarded Sunday would just repeat step 2's own already-failed lookup
once (same pure inputs, same None) and return [] normally. Rewritten
to say what is actually true: the guard exists because a Sunday has
no PRECEDING Sunday to resume, not because skipping it would be
dangerous; the chain terminates because every step consults data or a
strictly earlier date, and no step ever calls back into readings.
3. Correcting the record, per instruction, rather than amending
ba0adba: that commit's own body said Advent ferias carry 'Advent I's
own readings copied onto the following Monday-Thursday'. Both details
are wrong, verified directly against data/ef/lectionary.sexp: the
duplicated readings are ef-advent-SUNDAY-2's (Rom 15:4-13 / Matt
11:2-10), not Advent I's, and they appear on ef-advent-2-monday,
-tuesday, -thursday and -saturday -- four non-contiguous days, not a
Monday-to-Thursday span. The in-code comment and the task-5 brief's
own commit template both already said 'Advent II' correctly; only
ba0adba's commit body had the error.
dune test --force: 344 tests, all green (unchanged count -- one test's
body changed, none added or removed).

Chain step 3. Guarded on weekday <> Sun: a Sunday reaching this branch
would look up its own slug via days_since_sunday Sun = 0 and loop --
every other chain step consults data, this one consults a strictly
earlier date, so that guard is the whole chain's termination argument.
Reaches the Sunday by Date.add_days plus a fresh temporal_at call, never
by string surgery on the day's own slug -- the slug shapes are genuinely
inconsistent across seasons (ef-advent-sunday-1 vs ef-advent-1-monday,
week number on opposite sides of the season name).
Uses the preceding Sunday's TEMPORAL slug, never its observed one: the
rubric is the preceding Sunday's Mass even in a year a feast displaced
that Sunday from being observed (pinned: 2028-12-26, the Monday after a
Vigil-displaced Advent IV Sunday, still takes Advent IV's Mass).
Measured over the full 1583-9999 domain (temporal cycle only, no
sanctoral contest): of 412 distinct temporal slugs, 305 carry no
lectionary entry of their own; of the 304 that are feria (non-Sunday)
slugs, step 3 alone resolves 297 of them via their preceding Sunday.
The 7 that remain, plus the 1 uncovered Sunday slug itself
(ef-holy-name-sunday), all trace to the same two missing lectionary
entries (Holy Name Sunday and 30 December), not to eight independent
gaps or a step-3 defect -- traced date-by-date, not merely counted.
Day-level effect, 2005-2050 (full Precedence+Calendar pipeline,
matching this project's existing differential window): 16807 days,
16531 resolved (98.36%), 276 still empty; step 3 alone accounts for
4503 of the resolved days, more than either step 1 or step 2.
Warrant is the same class as step 2's, not a confirmed Missal
citation: lectio hard-codes this shape as literal duplicated data on
the four Advent ferias (Advent I's own readings copied onto the
following Monday-Thursday) and leaves the rest of that same shape
simply absent; step 3 turns the duplication into a rule.
dune test --force: 344 tests, all green (was 340).

Critical (coordinator review): a clean `dune build` produced a `colitur`
that died at startup on EVERY subcommand, including ones touching no
lectionary data at all. Root cause was two-fold: data/ef/lectionary.sexp was
never added to the root default-build alias (only materialised as a side
effect of the test suite's own deps, which is why every check in the prior
report passed), and Rite_ef.context loaded it as a module-init side effect
via failwith, undoing Lectionary.load's own "never raises" promise at a
point no caller could catch.
Fixed structurally: Rite_ef.context is now a function taking ~lectionary,
Lectionary_ef.readings takes ~lectionary, and neither touches the filesystem
any more -- the same caller-supplied discipline the sanctoral layer already
had, restoring rite_ef.mli's own pre-existing claim about it and leaving a
seam for a future diocesan lectionary overlay. bin/main.ml grows
load_ef_lectionary, a sibling of load_ef_layer, routed through the same
colitur: %s / exit 2 path. data/ef/lectionary.sexp added to the root default
alias. Every caller of Rite_ef.context updated to supply it.
Also: two new tests that genuinely distinguish chain step 1 from step 2
(19 March 2026, Joseph's own proper over a competing temporal entry; 13
January 2030, Holy Family reached only through the temporal slug, the
Baptism entirely absent) -- the prior two tests both survived swapping the
chain order. Both new pins verified directly against the real data. The
chain's own comment now states plainly that its warrant is lectio's observed
behaviour, not a confirmed Missal citation, per the rules register's own
open item.

Liturgical_day.citations has read "always empty until Plan 4" since Plan 3;
it is now filled. Rite.t gains a readings function, rite-supplied for the
same reason transfer_target is: what a day with no proper falls back to is a
rubric, not a universal. Calendar calls it and passes its own temporal
function as the callback the rite needs to reach another date.
Steps 1 and 2 only: the observed celebration's own proper, else the day's own
temporal slug. Nothing encodes "Lent has daily propers" -- the presence of an
entry is the discriminator.

Sexplib.Sexp.load_sexp raises bare Failure for several malformed inputs
(unterminated list/string, empty file, more than one sexp) rather than
Sexplib.Sexp.Parse_error, so those cases escaped Lectionary.load as an
uncaught exception -- breaking the .mli's own promise and the kernel's
never-raises-on-fallible-construction constraint. Mirrors the catch-all
already present in Layer.load and Overlay.load, plus a second catch-all
on the t_of_sexp branch for defence in depth.
Adds test_load_never_raises, covering all of the above plus a missing
file, using Filename.temp_file rather than a hardcoded path. Verified the
new test fails against the pre-fix load (uncaught Failure) and passes
against the fix.
|
| |
|
|
|
|
|
| |
Data only, the same shape and discipline as Layer: slug-canonical,
duplicates rejected at construction naming the offending slug, sexp
round-trips. Which slug a day falls back to is a rubric and belongs to the
rite module, so nothing here knows about ferias or Sundays.

Five follow-ups from the fix-round re-review, none touching a computed
result.
M20's note had said "moderate-high, not certain" with a specific revisit
trigger attached. The fix round raised the label to "near-certain" and
deleted the trigger in the same edit. Upgrading a confidence while
removing the condition that would lower it again is the one move this
record must not make, so the trigger is restored alongside the higher
label: no primary text anywhere names the Major Litanies in a
Mass-orations-count worked example, only the general II-class-Sunday
rule twice over. RG 434(b) closes the Office-shaped doubt and nothing
further.
"WORD-IDENTICAL" overstated the relation between RG 111(b) and n.
434(b). Only the trailing "quae tamen omittitur si commemoratio
privilegiata facienda sit" is verbatim in both; the openings differ,
n. 434(b) recasting the rule into the orations register. The claim was
self-refuting -- both texts are quoted adjacent to it -- and the
argument never depended on it. Now "identical in its operative clause".
And n. 434 is not "a different part of the same document": the running
heads put RG 111 under Rubricae generales and n. 434 under Rubricae
generales Missalis Romani, two distinct corpora bound in one volume,
which is the entire force of the corroboration. The code comment had
understated its own point.
Also corrects the register's LT line range for n. 434(b) (3574-3576, not
3564-3570; the (b) clause is not in the cited range), and records in
calendar.ml the diagnostic that channel (3) trades away: a rite whose
transfer_target names a date its own disposition omits used to raise a
loud, mislabelled Validate failure and is now silent at the origin. The
kernel cannot distinguish that from a deliberate omission without rite
knowledge it must not have, so accepting it is right -- but the signal
is gone, and that should be written down rather than discovered later.

attribution, RG434(b)
F2: the task report's "colour/subject/names on the Litanies entry are
currently inert" was false for names -- test_oracle.ml's identity axis
reads Names.find on every commemoration, and the invented English name is
exactly why 2026-04-25 registers as a Comm_identity_mismatch, the reason
M5 had to be re-gated. Corrected precisely, field by field, in the report.
F3: Easter 2027 is 28 March, not 18 April, as previously stated in the
report's own "layer 4 is blind to the transfer" reasoning. The conclusion
survives (28 March is not 25 April); the date is corrected.
F4: "the exhaustive property sweep caught this immediately" was a wrong
attribution, in the report, the register, and calendar.ml's own comment.
The committed exhaustive sweep walks 1583-9998 in order and aborts at the
first failure; the years actually reported (5700, 4747) were draws from
prop_invariants, the default dune test run's 200-year random sample.
Corrected in all three places.
F5: the Litanies' privileged commemoration is due in the MASS specifically
(RG 108 + RG 81), never a separate Office answer -- colitur emits one
resolved day, and the M20 adjudication rests on that being the Mass
reading. Stated explicitly now in M20's own note, the register, and
precedence_ef.ml's own RG111(b) comment.
Also added to M20 and the register: Rubricae Generales Missalis Romani
n. 434(b) ("VIII - De diversis Missae partibus", "D) De orationibus", "I
- De orationibus in genere"), verified word for word against all three
documents -- word-identical to RG 111(b) but explicitly scoped to the
Mass ("post orationem Missae"), answering the objection that RG 111
(Caput XVI, which RG 106 says governs both Office and Mass) might be read
as Office-shaped. Moves the M20 adjudication from "moderate-high, not
certain" to near-certain.

(fix round 1, F1)
The prior fix (settled_at) recognised two settlement channels for a
transferred candidate at its target -- winning outright (observed) or
surviving as a commemoration -- but missed a third: reaching the target
and then being CAPPED OUT there, by admit's own RG-111-style admission
count limit or by disposition's own Omit. That candidate lands in the
target's own omitted list, genuinely settled and accurately labelled, but
settled_at did not check that list, so the origin reported it as
unresolved under the same wrong, hardcoded unconverged_reason -- the exact
original bug, one level further out.
Unreachable on shipped EF data (the Major Litanies are the only privileged
Commemoration_only candidate real data carries, and no second one can ever
share Easter+2), but reachable by construction: a second privileged
Commemoration_only entry on the Litanies' own transfer target that
outranks it in admit's Class1 selection, or -- without any synthetic data
-- forcing the Litanies' own RG 109(f) privilege to Ordinary, which makes
the transferred candidate lose that same cap against its own real target.
Fixed by adding target-omitted membership as a third disjunct in
settled_at. New regression test in test_calendar.ml, built the same way:
the real EF layer plus one synthetic privileged Commemoration_only entry
on the real 2011 transfer target, sorting ahead of the Litanies so it wins
the Class1 slot. Mutation-verified to fail specifically when the third
disjunct is removed. COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force stays
clean after the fix, confirming it changes no shipped day's output.

RG 80 (Caput X, "De Litaniis maioribus et minoribus", A): the Major
Litanies are assigned to 25 April, transferred to the following Tuesday
(always Easter+2) when that date is Easter Sunday or Easter Monday. RG 81,
same division: nothing is done in the Office, only in the Mass. RG 109(f)
(Caput XVI): a privileged commemoration.
Entity: Commemoration_only, Fixed(4,25), via data/ef/adjustments.sexp's
`Add major-litanies` -- RG 81 denies it Office standing entirely, which is
exactly what Commemoration_only already means to Precedence.resolve (held
out of the observed contest by construction). Rank Class4 deliberately,
not Class1, to keep the new RG109(f) privilege branch live rather than
shadowed by privilege_of's existing "of a I-class day" branch. Colour
Violet by consistency with the sibling Minor Litanies; subject Saint, the
same "no special exclusion" default this codebase's other
Commemoration_only entries use. Names not primary-sourced, flagged as such
in the data file's own comment.
Transfer: reuses the existing RG 96 placement machinery
(Precedence.disposition's Transfer constructor + Calendar's
place_transfers/resolve_with_injected) rather than a new candidate
channel -- RG 80's own transfer is structurally the same operation RG 96
already performs for an impeded I-class feast. disposition gains a branch,
checked before the Commemoration_only catch-all: the Litanies losing to
winner slug "ef-easter-sunday" or "ef-easter-1-monday" is Transfer, not
Commemorate. transfer_target gains a branch, checked before the general
RG 96 search is even computed, returning Easter+2 directly with no search
at all -- necessary, not merely simpler, since Easter+2 is itself I-class
and a search from there would walk past the exact day RG 80 names (a
commemoration needs no unoccupied day the way a displaced feast does).
Privilege: privilege_of's previously-dead RG 109(f) branch now recognises
the Litanies' own slug. No other code change -- admit's existing
Class1/Class2-Sunday branches already implement "a privileged
commemoration categorically takes the slot" correctly, from an earlier
task.
Full blast-radius measurement, adjudication of the resulting missalemeum
divergence, and the mutation proofs are in the task's own report,
.superpowers/sdd/2026-08-12-colitur-rg16a/major-litanies-report.md.

as observed
Calendar.build_day's `unresolved` check decided whether a Transfer-disposed
candidate had genuinely settled at its target by checking only whether it
became that day's own `observed` celebration. That was correct for every
prior use of Precedence.Transfer: a losing FEAST, which RG-96-style rules
guarantee an unblocked target to win outright once it arrives.
It is not correct in general. A rite's rules are free to dispose a
Celebration.status = Commemoration_only candidate as Transfer too (the EF
Major Litanies, RG 80, do exactly this) -- and such a candidate can never
become `observed` anywhere, by the same status that makes it eligible to
transfer in the first place. The old check mislabelled a cleanly-settled
transfer of that shape as "did not converge" (a hardcoded string, not a
real read of the placement pass's own convergence) and double-counted it
in Validate's own duplicated-sighting check.
Replaced with `settled_at`, which re-resolves the target date and accepts
either `observed` or membership in that day's own admitted commemorations.
A strict superset of the old check -- every existing use (a transferred
feast winning its target) is unaffected -- and stays rite-agnostic: it
reads only Precedence.resolution's existing fields, no EF-specific
knowledge added to the kernel.
Found by the exhaustive property sweep (COLITUR_EXHAUSTIVE_SWEEP=1) the
moment a rite first produced this shape, not anticipated in advance.

Three corrections from the fix-round re-review, none changing behaviour.
RG 431(e) was attributed to "Caput XX, De hymno Gloria in excelsis".
There is no Caput XX -- the Rubricae Generales' Caput series ends at
XIX. The paragraph number, letter and subsection title were all right;
only the containing division was invented. It sits under "VIII -- De
diversis Missae partibus", subsection "C) De hymno Gloria in excelsis".
Shipping a new invented structural citation in the very round that
corrected a source-fidelity overclaim is what the gate exists to catch.
marian_slugs claimed TWO entries found and deliberately excluded after
individual consideration, "not merely omitted". There was a third:
vigil-of-the-assumption, 14 August, which is de B. Maria Virg. and whose
collect implores her protection. It was merely omitted. Added to the
list -- behaviourally inert, verified: it wins 7196 times domain-wide,
always with the non-Marian eusebius-confessor as its only commemoration,
and never loses -- but a closed list's whole value is its enumeration
claim, and that claim was false as written.
And the new rule has no comparison-layer witness at all. Reverting it
reddens three tests, none of them a comparison layer: the differential's
row type carries no commemorations, and the oracle's window has no
16-July Saturday. Worse, lectio's fixture DOES carry commemorations and
prints +our-lady-of-mt-carmel on all 8 in-window dates where colitur now
prints nothing -- a real divergence, neither fixed nor cited, swallowed
by a blind spot, which binding decision 1 forbids. Recorded, with the
note that colitur's reading here has no reference confirmation anywhere
and only extending the oracle fixture to 2033 or later would settle it.
Also records the RG 112(d) branch's ordering constraint: it precedes RG
95's Transfer branch, which it does not need to, and must move below it
if a Class1 Marian entry is ever added.

bvm_saturday_names's own comment: the "Missae de S. Maria in sabbato"
heading quote corrected from an overclaimed "both scans, word for word"
to showing both scans' own raw OCR (noisy, and genuinely differing in
abbreviation from each other) side by side, with the substance-only
corroboration stated plainly.
Colour citation tightened: RG 431(e) (the Missal's own classification
of this Mass as a "Missa votiva IV classis... de B. Maria Virg.") -> RG
121(a) (votive Masses take the colour of the feast-type they
correspond to) -> RG 120(b) (BVM feasts are white), replacing RG 120(b)
alone as the primary citation -- this Office is not itself a festum, so
RG 120(b)'s own "in Officio et Missa de festis" was a stretch as the
sole basis. Conclusion (white) unchanged.

The BVM Saturday Office is itself "de B. Maria Virg."; RG 112(d) (Caput
XVI, "De Commemorationibus") excludes another commemoration whose own
oration invokes the SAME BVM's intercession. our-lady-of-mt-carmel (16
July, Commemoration_only) was wrongly admitted as an ordinary
commemoration alongside the Office on every 16-July-Saturday -- its own
collect explicitly invokes "her" (eius) patronage, and both photographic
scans print a rubric anticipating exactly this collision (an either/or
of Mass texts, not a joint commemoration).
Precedence_ef gains marian_slugs (a closed, hand-verified list of
sanctoral slugs that are themselves feasts of the BVM) and is_bvm_office
(true for subject = Bvm OR a marian_slugs member -- the disjunction is
load-bearing: the Office is identified only by subject, since its own
slug is deliberately reused from the ordinary ferial fallback; Mt Carmel
is identified only by the list, since its own subject tag is Saint, not
Bvm). disposition gains a new branch, checked before the pre-existing
Commemoration_only catch-all, since the one live witness is
Commemoration_only and that branch's own "always Commemorate" had no
exception for this shape.
Checked exhaustively against every Marian-named sanctoral entry: only
Commemoration_only-status entries can ever reach this branch live (a
Feast-status one always wins outright instead of losing). Of the two
such entries in the data, only Mt Carmel is reachable --
our-lady-of-ransom (24 September) is provably unreachable: 24 September
falling on a Saturday forces 1 September to a Thursday, which by
construction makes 24 September the September Ember Saturday, Class2,
every time, not a sampled coincidence.
Re-measured against the full pre-change binary: the original 75,853-day
blast radius is unchanged in total, splitting into 74,633 colour-only +
1,220 colour+comms (16-July Saturdays). Mutation-tested: exactly 3 new
tests redden, nothing else.

RG 91 entry 27, "Officium sanctae Mariae in sabbato", sits in the Table
of Precedence between entry 26 (III-class vigils) and entry 28 (IV-class
ferias). Precedence_ef.band already routed a plain IV-class Saturday
feria to entry 27's own band value, but nothing in Temporal_ef.temporal
ever constructed the office itself, so an otherwise-unoccupied Saturday
still surfaced with a bare ferial slug and its season's ordinary colour.
Established from Caput IX of the Rubricae Generales, both photographic
scans and the electronic transcription, word for word (no
scan-vs-transcription conflict: RG 78/79 are General Rubrics prose, not
the Mass-propers body text the transcription is documented elsewhere as
missing almost all of):
"78. In sabbatis, in quibus occurrit Officium de feria IV classis, fit
de sancta Maria in sabbato.
79. Officium sanctae Mariae in sabbato incipit a Matutino et explicit
post Nonam."
RG 78's own protasis IS "otherwise unoccupied IV-class Saturday" --
every Saturday whose temporal candidate would otherwise be Class4,
across every season that rank reaches (Christmastide, Septuagesima,
Time after Epiphany, Time after Pentecost, ordinary Paschaltide).
Nothing else was needed to decide "otherwise unoccupied": band's own
entry-27 branch already reads rank/weekday on the temporal candidate
unconditionally and only wins the day when nothing outranks it -- RG
78's own condition, decided by the existing occurrence machinery.
Colour is white, unconditionally, per RG 120(b) ("Adhibetur color albus
in Officio et Missa de festis: ... b) B. Mariae Virg."), not RG 119/127/
128's seasonal rules -- this office is never "de Tempore" for colour
purposes, so it overrides the season's own violet/green.
The slug is deliberately left UNCHANGED (reused from whatever the
generic <season>-<week>-<weekday> ferial fallback would already have
produced), for two independent reasons: it matches the Sacred Triduum's
own precedent (identified structurally, off rank/weekday, never off the
slug), and a bespoke uniform slug would have broken
Colitur_kernel.Validate's own slug-uniqueness-per-liturgical-year
invariant, sighted zero times before this task -- confirmed directly by
writing it that way first and watching the landmark-years test fail.
Subject is tagged Bvm (currently inert for precedence -- only Lord is
ever read by band/disposition/admit) and the name is the Latin
"Officium sanctae Mariae in sabbato" (RG 91 entry 27's own table title
and RG 79's own heading), deliberately not English, the same
zero-circularity discipline Holy Family/Holy Name/the Sacred Triduum
already established.
The I-V numbered "Missae de sancta Maria in sabbato" (both scans) are a
Mass-propers selection detail (RG 309(a): "iuxta temporum diversitatem")
governing which readings/texts are said, not which office is kept --
colitur computes no citations yet (Plan 4), so this is deliberately not
modelled here.
Two pre-existing tests needed correction, not because they were wrong
before, but because RG 78 genuinely changes their dates' own facts: a
Saturday inside the Holy Name of Jesus window (3 January) and two
Saturdays inside christmastide_feria_slug's own "-0-"/"-2-" stretches
(26 December, 10 January) are all otherwise-unoccupied Class4 Saturdays,
so they now legitimately carry the BVM office instead of staying a bare
Temporal-subject feria.

Two corrections from the fix-round review, both to the record.
"Sabbato Sancto" is attested zero times in either photographic scan. The
scans print SABBATO SANCTO as the heading (once) and "Sabbato sancto" as
the running header (28x and 30x); the shipped casing appears only in the
electronic transcription's table of contents -- the source this
project's own methodology rule deprecates -- while the comment beside it
called the value "both photographic scans, word for word". Recased to
the running-header form, which is the convention the other three Latin
names in the file already follow, with a source note recording the
count. Third source-fidelity slip this week, and the first where the
wrong value came from the deprecated source itself.
The Major Litanies deferral was recorded with two false blockers. It
claimed a kernel signature extension was needed to suppress the feast in
transfer years: admit already takes ~temporal and disposition already
takes ~winner, both carrying the Easter office on 25 April, so a
rite-local slug test does it with zero kernel surface. And it implied
Easter Monday is unmarkable: ef-easter-1-monday occurs exactly 8417
times in 8417 years, as reliable as ef-easter-sunday. So the guarded
build -- never scored -- is a strict improvement, 8223 years newly
correct against 194 unchanged, and "worse than the gap" was true only of
the unguarded one.
Deferring is still right, for a reason nobody had found: 25 April is St
Mark, II class, so under RG 111(c) a privileged Litanies commemoration
would displace the day's existing ordinary commemoration in ~97.7% of
years -- an unmeasured blast radius through layers 3 and 4. That
measurement is the prerequisite. The 194 figure is exact and reproduces.
Also corrects a subject-audit list that named five months for six
entries, omitting the Precious Blood on 1 July.

Holy Thursday, Good Friday and Holy Saturday resolved to the generic
Passiontide ferial slugs with no distinct identity of their own -- rank
and colour were already correct (RG 91 entry 2; Holy Thursday's white
per RG 128(b)/RG 122), only Celebration.names/subject were missing.
Keeps the slug (RG 91 entry 2 is identified structurally, off rank and
Easter offset, by Precedence_ef.band -- never off the slug -- so
renaming it would touch precedence for no reason and break the lectio
differential's own slug mapping for these three lectionary keys, the
same reasoning already given for Holy Family/Holy Name). Carries the
identity in Celebration.names instead, the same treatment those two
established: Latin, not English, to avoid reading the oracle this axis
is compared against.
Names sourced from both photographic scans, word for word, corroborated
by the electronic transcription's own table-of-contents-style listing at
the identical three headings (three-way agreement, nothing to
adjudicate): "Feria V in Cena Domini" (Holy Thursday), "Feria VI in
Passione et Morte Domini" (Good Friday -- not the transcription's own
informal "Feria VI Parasceve" used in passing elsewhere), "Sabbato
Sancto" (Holy Saturday).
Also tags subject = Lord, going further than Holy Family/Holy Name
strictly required (they needed it only because band's entry 14 reads
subject to outrank a colliding fixed feast; entry 2 here needs no such
thing). Safe: disposition's RG 112(a) branch only fires when both sides
of an occurrence are tagged Lord, and no Lord-subject sanctoral entry
has a fixed civil date inside Holy Week's own movable range; any Class1
sanctoral entry landing there (e.g. a transferred Annunciation) reaches
disposition's earlier, subject-blind Transfer branch first regardless.
Verified against the full 1583-9999 domain: zero
observed/commemorations/transferred_* difference traceable to the tag.
test_golden.ml's describe gains a name_la field alongside subject, for
the same reason subject was added: a names-only change is otherwise
invisible to every pin whose rank/colour/slug are already correct (this
task's own catalogued vacuity flavour #1). Six existing pins move from
subject=temporal to subject=lord (the three Easter-extreme Holy Saturday
pins, 2016's Good Friday, and the 2026 Holy Thursday/Good Friday pair);
the rest gain name_la=- by construction (no other temporal-cycle
candidate carries a name yet).
Mutation-tested: reverting temporal_ef.ml alone (keeping the tests)
reddens the new Rite_ef unit test plus five golden pins across two
independent layers.

The re-review asked for a third commemoration in the shape-(c) row, so
that "spliced immediately after its trigger" could be told apart from
"appended at the end" -- it had proved an append-at-end variant passed
the whole suite green, the pair alone being too short to distinguish
them.
Attempting it establishes something better than the test requested. On
this day-shape a third commemoration is rubrically impossible. Shape (c)
requires the trigger to lose the day while still being admitted, and a
Class2 trigger can only lose to a I-class day (RG 111(a): one privileged
commemoration) or a II-class Sunday (RG 111(b): one, "scilicet de festo
II classis"). Both caps are one. The third candidate is now offered and
correctly refused, which is the assertion worth having.
So RG 110(c)'s "ante omnes alias commemorationes" half has no reachable
witness in the EF's rubrical space, and the re-review's own finding that
shape (c) never co-occurs with a third commemoration across 8417 years
is a consequence of the rubric rather than an accident of the data. The
append-at-end variant stays indistinguishable from the splice on every
input the engine can construct. Recorded rather than papered over with a
synthetic row proving a shape no rubric permits.
Also drops Record from the "nothing compares commemoration order" note
-- Record.t has no commemorations field at all -- and names, at
privilege_of's own (a) branch, that the Holy Name's Sunday privilege
currently rests on a substring match rather than on RG 17's closing
paragraph, which is its real warrant.

RG 110(c), word for word: "quoties vero oratio unius Apostoli addenda
est ad modum commemorationis, huic orationi additur altera immediate,
ante omnes alias commemorationes." "Huic orationi" (dative, "to this
oration") refers to the trigger's own oration; "additur altera" means
the companion is added to it, i.e. follows it. "Ante omnes alias
commemorationes" governs the pair's position relative to other,
unrelated commemorations, not the pair's own internal order. The
previous build prepended the companion uniformly in both RG 110
shapes, citing this same clause for both -- correct for (a)/(b) (the
day's own oration, not a list member, has nothing to order against),
backwards for (c), where the trigger is itself a list member and the
companion belongs after it. Fixed in rg110_additions: shape (a)/(b)
still prepends; shape (c) now splices the companion in immediately
after its own trigger. Re-pinned the unit test that had asserted the
wrong order, and corrected both rows' comments to cite the clause that
actually governs each shape.
No layer in this codebase compares commemoration order: the lectio
differential never compares commemorations, the oracle sorts both
sides into a multiset, and the golden tests' own describe function
sorts its commemorations field too. Recorded as a new, permanent blind
spot in CLAUDE.md and the register, not merely fixed around -- the
admit_cases unit table is the only place order is asserted at all.
Re-measured the full blast radius against the same pre-change binary:
same 14,627 differing days, same four shapes and counts, confirming
the fix changed only the content of the 593 shape-(c) rows and nothing
else. Mutation-tested: reverting the splice back to a uniform prepend
reddens exactly the shape-(c) unit test; a new golden pin for a real
shape-(c) day (2004-02-22) stays green under the same mutation, living
proof that golden pins cannot see this axis, not merely a claim.
Separately, M19's own predicate checked a date and a diff shape but
not which candidate -- proved insufficient by fabricating a second,
bogus companion on 30 June and confirming the whole suite stayed
green. Fixed by requiring the admitted commemoration to be exactly
commemoration-of-st-peter, mirroring C16's own identity guard. Added a
golden pin for 30 June, the only assertion of that entry's identity
outside the allow-list.
Also: corrected a false claim in the task report that the electronic
transcription carries no corroboration of the Holy Name fallback --
its own table of contents does, at a line not checked on the first
pass. Added two further citations, both re-verified against the scan:
RG 17's own closing paragraph, settling the Sunday shape's Sunday-
exclusion at the rubric level rather than only in the propers; RG
124(c), which assigns red to 30 June by paragraph number rather than
by the generic apostle/martyr default. Noted the fragility of deriving
the Sunday shape's RG 109(a) privilege from a slug-substring match
rather than from a citation. Cosmetic: a stray blank line and an
indentation inconsistency.

RG 110 (Caput XIV): "In Officio et Missa S. Petri semper fit
commemoratio S. Pauli, et vicissim... pro unica habeantur" -- in the
Office and Mass of either Peter or Paul, a commemoration of the other
is always made, uncapped by RG 111's own admission count. Both
photographic scans, full text including sub-clause (c) (a separate
trigger this register previously had not transcribed: the same rule
also fires when one Apostle's oration is admitted merely as an
ordinary/privileged commemoration, not only when it is the day's own
office).
Three real pairs in the 1962 calendar, all confirmed on both scans:
25 January (conversion-of-st-paul + peter), 22 February
(chair-of-st-peter + paul), 30 June
(in-commemoratione-sancti-pauli-apostoli + a new
commemoration-of-st-peter). The first two already existed as ordinary
sanctoral candidates but were wired into RG 111's ordinary, capped
admission contest instead of this rule's own uncapped one -- the
defect this closes. 30 June had no companion at all: a genuine gap
in lectio's own source data (confirmed directly against
tridentine-calendar.ini) and in missalemeum's own oracle output for
both fixture years, not only a colitur bootstrap miss, so colitur is
now uniquely correct on this date among the three engines compared.
Added via data/ef/adjustments.sexp's own Add directive, the
architecture's existing extension point for exactly this shape of
gap, since data/ef/sanctoral.sexp is generated and lectio must not be
touched.
Precedence_ef.admit gained rg110_additions/rg110_companion_slug,
layered on after admit's own four ordinarily-capped branches decide
their normal result: checks both the observed candidate and every
already-admitted candidate against the three-pair lookup and prepends
any companion found, uncapped and additional, never competing for
RG 111's own slot.
Measured full blast radius (1583-9999, pre-change binary from git
archive at 59fbda8 vs the fixed binary, 3,074,246 days each side,
14,627 differing days, all four predicted shapes, zero unclassified):
3,619 Holy Name fallback days (previous commit), 3,533 days Paul was
wrongly excluded from Chair of St Peter's own day by a competing
privileged feria, 593 days Chair of St Peter itself was admitted only
as an ordinary commemoration with Paul entirely absent, and 6,882 days
the new 30 June companion is added. The 3,533+593 figure supersedes an
earlier, narrower 852-day estimate that measured only the delta
between two older code commits, not the rule's full scope.
The lectio differential needed no change: it does not compare
commemorations at all, and this fix never touches season, slug, rank,
or colour. The missalemeum oracle allow-list needed three changes:
M12 removed (22 February 2027 no longer diverges in commemoration
count), M15's date list gained 2027-02-22 (now reaching identity
comparison for the first time, where it lands on that entry's own
pre-existing, unrelated limit -- one of the two commemorations is
temporal-origin and unnamed), and a new M19 for the 30 June gap.
Mutation-tested, both halves separately: disabling the admit-level
addition reddens the two new unit tests, the oracle's own M12-shaped
checks, and an existing golden pin (updated to expect the Paul
companion); removing only the 30 June data entry reddens solely the
oracle's new M19 count, confirming the code and data halves are
independently load-bearing.

RG 17(a): "festum Ss.mi Nominis Iesu, celebrandum dominica quae occurrit
a die 2 ad 5 ianuarii (secus die 2 ianuarii)" -- both photographic scans,
confirmed on the calendarium's own January table and the Mass propers'
own heading. Two defects closed together, since they interact through
RG 91 entry 14/RG 16(a):
1. The Sunday shape (2-5 January) now tags subject = Lord, matching
RG 91 entry 14 ("Festa Domini II classis") -- previously subject =
Temporal, the same defect shape Holy Family had before it.
2. The fallback (RG 17(a)'s own "secus die 2 ianuarii", the calendarium's
"vel, ea deficiente, die 2 ianuarii") is now built: 2 January carries
the feast whenever no Sunday falls 2-5 January that year. Before this
fix colitur emitted no Holy Name office at all in such a year -- a
real II-class feast simply missing, on 3,619 of 8,417 years in the
domain (43%; 20 of the 46 years 2005-2050, independently re-derived
against `date -d`).
Both shapes band identically at RG 91 entry 14's MOVABLE half
(Precedence_ef.entry_14_movable_band) -- one feast, not two differently
classified ones, per the Mass propers' own single heading covering both
dates. No live collision exists in the current sanctoral data (nothing
fixed-date falls 2-5 January besides a Commemoration_only entry on 5
Jan), so the RG 16(a)/RG 112(a) interaction is proved with synthetic
precedence-level fixtures mirroring Holy Family's own precedent, not a
live-data regression. One asymmetry the synthetic tests found and kept
honest rather than forced: a losing Holy-Name-Sunday is privileged
(RG 109(a), "of a Sunday") and survives RG 111(a)'s cap; a losing
Holy-Name-fallback is not (2 January is not a Sunday, and no other
RG 109(a)-(f) category applies to it), so it gets no commemoration at
all if ever outranked -- both individually correct readings of RG 109/111's
closed lists.
Golden pins follow the brief's own vacuity warning: the Sunday shape
already emitted the right slug/rank/colour before this fix (an ordinary
Sunday and Holy Name coincide on those fields), so its pin asserts
subject explicitly rather than pinning the whole line uncritically; the
fallback pin (2029-01-02) is the one with teeth against the larger
defect, reddening on slug/rank/subject together if reverted.
Mutation-tested: each half of the fix reverted separately reddens
exactly its own tests (Sunday subject: the dedicated unit test, the
golden pin's subject field, one precedence end-to-end test; fallback:
the fallback unit/anchor/golden tests, the new C16 differential count,
and both shapes of the precedence end-to-end tests) and nothing else.
Adds data/ef/expected-divergences.sexp's C16 (lectio has no fallback for
this window at all) -- the lectio differential's own count, independently
re-derived against `date -d` for the fixture's 2005-2050 span, not
transcribed from the domain-wide figure. The missalemeum oracle window
(2026-2027) exercises only the Sunday shape and needed no new entry:
subject is not one of its compared fields, and both years' rows already
corroborate the Sunday-shape ranking (missalemeum's own 2026-01-04 and
2027-01-03 rows: rank 2, white, title "Holy Name of Jesus").

Both are the defect class this fix round existed to close, which is why
they are worth recording rather than quietly overwriting.
CLAUDE.md still carried F1's retracted design rationale -- describing
entry_14_movable_band as "negative so it can never collide with a real
table position" -- and F2's retracted transcription-defect attribution,
verbatim, in the one tracked file the project's own workflow tells a
fresh session to read first. The fix round struck both everywhere else
and missed this file. A session following it as instructed could have
re-derived the negative sentinel for entry 20's or entry 23's movable
half and re-introduced the inversion in a new branch.
precedence_ef.ml's replacement justification for the x10 rescale then
introduced a fresh misstatement of the same primary text it was
correcting: it attributed "primum mobilia, deinde fixa" to "entry 12's
own ninth sub-item" and counted three such rows. Both photographic
scans, and the register's own section 4 table, put that clause at entry
13; entry 12 has eight sub-items and no such clause. The split occurs at
five rows -- 13, 14, 20, 23's third sub-item, and 24. Entry 24 is the
most-evaluated band in the whole domain and is unsplit in the code,
which is precisely the sub-rank the new headroom exists to hold.
Corrected in the .mli and the register too. No behaviour change; 290
tests green.

On 7,197 of the 8,417 days Holy Family occurs (every year that
isn't the 13-January collision), every emitted byte was identical to
the pre-change binary -- subject appeared in no output path the CLI
or any test read. Celebration.make already takes ?names, defaulting
to empty, and Temporal_ef.build never passed it.
build now takes an optional ?names, set only on Holy Family's own
branch: a LATIN name, not English. The oracle's own observed-identity
axis (test_oracle.ml) reads only `en`, so this is deliberately
invisible to it -- an English name here would mean reading
missalemeum's own title text, the oracle this exact axis is compared
against, to decide colitur's "ground truth" name: the "expected value
promoted from actual output" vacuity flavour this project's review
process watches for. Latin has no such circularity: the calendarium's
own January table and the Mass propers' own heading, both
photographic scans, word for word, "Sanctae Familiae Iesu, Mariae,
Ioseph" -- the same genitive-title convention test_names.ml's own
worked example already uses for Easter ("Dominica Resurrectionis").
Every other temporal-cycle candidate, including the neighbouring
Sundays, still carries no name of any kind -- a targeted addition for
the one day this task built, not a claim that the general gap
(register's own open item on Holy Name of Jesus, RG 17(a)) is closed.

cite RG95's real primary authority
F2: the disposition comment for RG112(a) claimed the electronic
transcription "carries NEITHER this paragraph's own worked example
NOR its own more specific Mass-proper rubric... exactly the
transcription's documented defect" -- wrong on both counts, checked
directly rather than taken on trust.
RG 112 has no worked example in any of the three source documents
(the transcription included) -- there was nothing to drop. The Holy
Family Mass propers' own 13-January rubric is absent from the
transcription not because it silently drops content it otherwise
has (the project's own documented defect, dropped calendarium
commemoration lines) but because that specific document (a 2006 web
capture) contains almost no Mass-propers text of any day: 5
Introit-line occurrences across 26,322 lines, against 61 and 402 in
the two photographic scans; its own "Proprium de Tempore" page is a
table of contents linking to PDFs the capture never pulled in. A
coverage gap in a partial web capture, not an instance of the
narrower, different defect the methodology note actually describes.
The ruling is unaffected -- the propers' quotation is real, on two
independent photographic scans, and settles 13 January on its own --
only the attribution is struck, here and in test_precedence_ef.ml
(the register and the task report are corrected separately).
F7: RG 95's own second paragraph -- present in all three documents,
including the transcription -- is a more direct, occurrence-level
authority for the exact collision than RG 112(a): "if two feasts of
the same Divine Person... occur together, the one higher in the
table is kept, the other omitted." Added as the primary citation on
disposition's RG112(a) branch, with RG 112(a) and the propers' note
kept as corroboration. Also corrects RG 112(b)'s own framing: it is
bidirectional ("et vicissim"), and only the Lord-feast-wins direction
(RG 16(a)) is implemented -- the Sunday-wins direction has no witness
anywhere in this codebase's data and was wrongly described as already
covered.

entry_14_movable_band = -14 was justified only by "cannot collide
with a real table position (1..28) or unclassified" -- a collision
argument, not an ordering one. band's own value is compared by plain
<, so a negative number beats every I-class entry (1-13), not merely
the fixed Baptism it was built to beat. Not live against the shipped
universal sanctoral data (no I-class universal feast falls 7-13
January, which is why the original 1583-9999 sweep showed only the
intended shape), but entries 12/13 admit PROPER and INDULT I-class
feasts too, and those arrive via adjustments.sexp-style overlays --
this architecture's own advertised extension path. A diocesan
patronal feast landing in Holy Family's window would have made the
inversion live immediately: the I-class feast displaced and
transferred to the next day, reproduced and confirmed before this
fix, reverted after.
Fixed by rescaling every band branch to the real RG 91 entry number
times ten (unclassified untouched at max_int) instead of the bare
1..28, reserving genuine headroom immediately before each entry for
a movable sub-rank -- not an arbitrary rescale: RG 91's own text
records a "primum mobilia, deinde fixa" split at three rows, not
only entry 14 (entry 12's own ninth sub-item, entry 14, and entry
20), so this leaves room for the other two without a second rescale
if either ever gets a live witness. entry_14_movable_band now
derives from entry_14_fixed_band - 1, tied together so they cannot
drift apart.
Added a synthetic I-class end-to-end test reproducing the exact
counter-example that found this: a universal I-class candidate
inside Holy Family's own 7-13 January window is now observed and
does not transfer, with Holy Family itself falling to RG109(a)'s
ordinary privileged-Sunday-commemoration path, the same treatment
any genuine feast outranking an ordinary Sunday gets.

Two related fixes, both needed for Holy Family to actually observe
correctly on the seven years it coincides with the fixed
Commemoration of the Baptism of the Lord (13 January): 2008, 2013,
2019, 2030, 2036, 2041, 2047.
band's entry 14 ("Festa Domini II classis") gated on sanctoral
origin only, so a movable Class2 Lord feast had no row in the table
at all. RG 91 entry 14's own text says otherwise: "primum mobilia,
deinde fixa" -- movable first, then fixed. entry_14_movable_band
gives Holy Family (the one movable candidate this codebase builds
with subject Lord) a value strictly better than the fixed half's own
literal 14, negative so it can never collide with a real table
position -- without it, the two would tie at 14 and fall to
Precedence.resolve's own alphabetical tie-break, which picks the
WRONG side ("commemoration-of-the-baptism-of-the-lord" sorts before
"ef-time-after-epiphany-sunday-1").
disposition gets a new branch for RG 112(a) (Caput XVI, "De
Commemorationibus"): the Office, Mass or commemoration of a mystery
of one Divine Person excludes a commemoration of another mystery of
the SAME Divine Person. Winner and loser both subject Lord -> Omit,
not Commemorate -- without it, Holy Family observing correctly still
left the Baptism admitted as an ordinary Class2 commemoration under
RG111(b), which the primary text does not allow.
Confirmed by a MORE SPECIFIC primary source than RG 112(a) alone: the
Holy Family Mass propers' own note, found on both photographic scans,
word for word, immediately after the Postcommunio -- "Si festum S.
Familiae occurrerit die 13 ianuarii, Missa dicitur de festo S.
Familiae, sine commemoratione Baptismatis D.N.I.C., et sine
commemoratione dominicae." The electronic transcription carries
neither this rubric nor RG 112(a)'s own worked example -- another
instance of its documented defect, not merely absent from one check.
Still expected red: the lectio differential (2005-2050) now shows a
new, real divergence on those seven 13-January-Sunday dates -- lectio
has no Holy Family at all, so it still shows the fixed Baptism
observed there, unlike colitur now. The oracle's own M-series entries
also still need widening for the observed-identity axis added two
commits ago. Both are the next commits.

RG 17(b), verified against both photographic scans (missale-romanum-
1962.pdf and "Missale Romanum 1962_text.pdf" -- the electronic
transcription carries the same paragraph, so this one is not itself
a transcription-vs-scan divergence): the Holy Family of Jesus, Mary
and Joseph is celebrated on the first Sunday after Epiphany, II
class, EVERY year, taking the Sunday's own place "cum omnibus
iuribus et privilegiis" -- the same formula RG 16(a) already uses.
The slug, rank and colour temporal_ef.ml already computed for that
Sunday (ef-time-after-epiphany-sunday-1, Class2, white) turn out to
be exactly right by coincidence -- an ordinary, unnamed Sunday and
Holy Family share both. The only field that was silently wrong is
subject: always Temporal before this, when RG 91 entry 14 ("Festa
Domini II classis, primum mobilia, deinde fixa") calls Holy Family a
movable Feast of the Lord. temporal's build now takes an optional
~subject, applied only on Holy Family's own date -- every other
Sunday, including the still-unbuilt Holy Name of Jesus (RG 17(a)),
is unaffected.
RG 17(b)'s window (7-13 January) can never be empty of a Sunday --
sunday_on_or_before(6 Jan) + 7 always lands in [7, 13] regardless of
6 January's weekday -- unlike RG 17(a)'s Holy Name (2-5 January, CAN
be empty), whose calendarium entry carries an explicit "vel ea
deficiente, die 2 ianuarii" fallback right next to Holy Family's own,
fallback-free one. No fallback needed or built.
Added to anchors (holy_family_sunday is independently computed, not
routed through named -- see temporal_ef.ml's own comment on why) and
to its own dedicated anchor/erosion test in test_temporal_ef.ml,
kept separate from the generic named-days coverage test since this
genuinely isn't one of named's own outputs.
Does not yet touch precedence: band still has no notion of a movable
Class2 Lord feast (entry 14 gates on sanctoral origin only), so on
the seven years 13 January is itself Holy Family's date (2008, 2013,
2019, 2030, 2036, 2041, 2047), the fixed Commemoration of the Baptism
of the Lord still wins the day exactly as before this commit -- the
next commit fixes the ordering RG 91 entry 14's own text states
("primum mobilia, deinde fixa").

All three are the project's own "correct code, wrong explanation" shape,
found by the final review of the RG 113 work. No behaviour change.
test_rite_ef.ml's registered Alcotest label said "Thomas of Villanova
observed, Maurice commemorated" while the test asserts the Ember
Wednesday is observed, Thomas is the sole commemoration and Maurice is
omitted -- the opposite of two of its three assertions. The body's own
doc comment was right; only the name a test run prints was wrong.
validate.ml's lead-in still said origin is reconstructed as Sanctoral
uniformly because the EF admit "reads only rank and slug, never origin".
That stopped being true in ea22ad2: admit now orders by band, and band
reads origin via is_temporal, so a temporal-origin commemoration
relabelled Sanctoral would be scored on the wrong table entry. The code
below already recovers the origin exactly; only this comment lagged.
precedence_ef.ml's band guard justified itself by citing
celebration.mli as saying a demoted feast retains its rank for RG 111's
admission-COUNT purposes. celebration.mli says the opposite -- it names
the ORDERING use the guard removes. The guard is right for a reason it
did not give: rank stays load-bearing through RG 111(b)'s "de festo II
classis" floor, which is what excludes these entries from a II-class
Sunday's slot. Both the citation and celebration.mli's own now-stale
line are corrected, each recording what it previously claimed.

Fix round 1 on the commemoration-identity/tie-break work: the "genuine
same-band tie" M17 adjudicated as open was not a tie at all. RG 91's
table enumerates only "dies liturgici" (real feasts) -- entry 24's own
text is "Festa III classis, in calendario Ecclesiae universae
inscripta" -- so a Celebration.t.status = Commemoration_only candidate
(a saint reduced to a bare commemoration) has no row in the table to
begin with. Precedence_ef.band used to read rank alone, so it silently
lent such a candidate the same table entry as a genuine Feast of its
own rank; the calendarium's own 22 September row confirms the
distinction in its own notation ("S. Thomae de Villanova ... III
classis. / Commemoratio Ss. Mauritii et Soc. Mm." -- Thomas carries a
class number, Maurice carries none).
Fixed at the source, not by adding a status tier to compare_precedence:
band now checks status first, ahead of every rank-keyed branch, and
returns unclassified for any Commemoration_only candidate. M17 deleted
(not re-adjudicated) -- 22 September now resolves identically on both
sides, with no divergence left to name.
Blast radius measured independently (a temporary git worktree at the
pre-fix commit): 4451 days change across the whole 1583-9999 domain,
exactly 4 verified shapes -- 3576 x maurice-and-companions-martyrs ->
thomas-of-villanova and 282 x eleutherius -> philip-neri (admitted set
changes), 502 x appollonia/cyril-of-alexandria and 91 x dorothy/titus
(order only, independently confirmed against the calendarium's own
listing convention). Zero days change who is observed. Further swept
the whole domain for a genuine "two different candidates on the
identical real table entry" residual -- the shape RG 113 truly gives
no instruction for -- and found it empty: of 109201 same-rank ties
domain-wide, 83950 now resolve by band alone and the remaining 25251
are exclusively two Commemoration_only candidates tied at unclassified,
never two real feasts. The residual admit still breaks alphabetically
is real, but narrower than previously documented.
The "66 days" figure is reconciled, not merely disputed: 599 is the
tie population, 65 (whole-comparator: 67) is the real admitted-set
decision count within it (independently reproduced against the
pre-Task-B binary), 149 is order-only. Every one of the 65 real
decisions traces to the same Commemoration_only/Feast root cause as
Maurice/Thomas.
Also: validate.ml's admission fixed-point check recovers a
commemoration's real origin (by matching its slug against the day's
own temporal office) instead of reconstructing every candidate as
Sanctoral, since band -- unlike EF's own admit -- does read origin;
precedence_ef.ml/.mli's motivating example and blast-radius claims
corrected to no longer rest on the fixed Maurice/Thomas case;
test_identity_rank_corroboration's own population count corrected now
that 22 September (and 21 other Feast-status matches) became reachable;
its rank-agreement pin documents exactly what it does and does not
prove. Register (§4, §6.1, §6 checklist) and CLAUDE.md corrected in
place, including the RG 113 first-sentence gap this exercise surfaced
but did not close, recorded as a new open item.
275 -> 276 tests (with the exhaustive sweep), all green.

precedence, not slug
Precedence_ef.admit broke a same-rank tie among commemoration candidates
alphabetically by slug -- a deterministic engineering convention with no
rubrical citation. RG 113's own second sentence, primary-source-verified
against two independent scans and previously uncited in the register
(only "commemoratio de Tempore fit primo loco" was quoted before), gives
the real rule: "in admittendis et ordinandis aliis commemorationibus,
servetur ordo tabellae praecedentiae" -- admitting and ordering
commemorations both run on the rite's own table of precedence (band's
28-entry table), not RG 8's coarse four-class rank.
Precedence.resolve now computes each commemoration candidate's own band
value once, generically, and hands it to rules.admit as a third tuple
element (Precedence.rules.admit's signature changed accordingly, ditto
Precedence_ef.admit; every rule-record stub in the test suite updated to
match). Precedence_ef.admit's own compare_dignity is replaced by
compare_precedence, ordering by band then slug; a residual tie within one
identical band value still falls back to slug, since RG 113 gives no
further instruction there -- documented as a still-uncited engineering
convention, not dressed up as a rubric.
RG 98 ("in paritate autem Officium prius impeditum praecedit") was
considered as a candidate authority for that residual and rejected: it
governs the transfer queue order among several simultaneously-impeded
I-class feasts (Caput XIII), a different operation in a different
chapter from RG 113's commemoration admission (Caput XVI); nothing in the
primary text connects the two.
Blast radius measured against the pre-change binary across the entire
1583-9999 domain (not only 2005-2050): the admitted-commemoration-slug
set is byte-identical, day for day, before and after this change. The
fix corrects the citation and mechanism, not the answer, on this
codebase's current data -- both of the task brief's named examples
(22 Feb Chair-of-Peter/Lent-vs-Paul, 22 Sept Maurice-vs-Thomas-of-
Villanova) are confirmed present and unchanged in both streams. A new
test (RG113: admit picks by precedence order, not slug, when they
disagree) proves admit actually consults the passed-in precedence value
with a synthetic pair whose slug order and precedence order disagree --
teeth a same-band-only regression test could not have caught, since
every real collision found in the domain happens to agree on both axes.
271 -> 272 tests, all green; COLITUR_EXHAUSTIVE_SWEEP=1 unaffected.

Fix round 1 review, MINOR finding (item 4). Both precedence_ef.ml and
test_precedence_ef.ml claimed the loser-side Class2 conjunct held because
'entry 6's own band value (6) is lower than every entry [3, 11-14]' --
false on its face (6 is not lower than 3) and, worse, the claim proves the
opposite of what it was cited for: if a band-3 candidate really did
contest a Class1 Sunday, the lower number would win, meaning the Sunday
would lose, not beat it as claimed.
The conclusion itself was never wrong, only the justification. Against
entries 11-14 (sanctoral-origin Lord feasts) the numeric argument holds
(6 < 11-14). Against entry 3 (Epiphany, Ascension, Trinity, Corpus
Christi, Sacred Heart, Christ the King) it is not numeric at all but
structural: every band-3 celebration is temporal-origin, and
Precedence.resolve takes exactly one temporal candidate per day, so a
band-3 Lord feast IS that date's own single temporal candidate, never a
second one contesting a separately-produced Sunday -- there is no band
comparison to make in the first place. Comment-only; no behaviour change.

day's own Sunday-ness, not observed
Fix round 1 review, two findings landed together because each golden pin's
correctness depends on both.
CRITICAL (item 1): reverts this branch's own first-pass retag of the
Purification (2 February) from Lord back to Bvm -> Lord. The calendarium
titles it 'B. Mariae Virg.', but missalemeum -- this project's designated
EF oracle -- treats it as taking an occurring II-class Sunday's place
outright, commemorations empty, exactly RG16(a)'s own festum Domini
treatment (2020-02-02, 2014-02-02, independently fetched). Control,
2019-09-08 (the Nativity of the BVM, an ordinary Marian feast, on a
Sunday): the Sunday observed, the feast merely commemorated -- the
opposite pattern, proving the Purification's own oracle treatment is
deliberate, not a gap. RG16(a) alone, on the untouched data, would have
matched the oracle character for character; retagging Bvm is what moved
colitur away from it on 1200 domain-wide days. The user has ruled: follow
the oracle. Genuine primary-text counter-evidence (RG120(b), the colour
rule grouping 2 February under 'B. Mariae Virg.', a category separate
from 'Domini') is recorded in the register, not discarded -- a different
project could reasonably rule the other way on the same evidence.
most-holy-name-of-mary stays retagged Bvm; that one was never disputed.
Removes the now-unneeded C12 lectio allow-list entry (data/ef/
expected-divergences.sexp, test_differential.ml): with the Purification
Lord again, colitur matches lectio's own class = lord on every affected
date, no divergence to allow-list.
IMPORTANT (item 2): Precedence.rules.admit gains a ~temporal parameter --
a genuine kernel signature change, unlike RG16(a) itself. RG111(b)'s own
Sunday rank floor ('one commemoration, namely of a II-class feast') used
to be detected by reading observed's own slug for a Sunday marker, which
silently assumed observed IS the day's temporal-cycle office. RG16(a)
breaks that assumption on purpose: a Feast of the Lord standing in for an
impeded Sunday 'cum omnibus iuribus et privilegiis' keeps the day a
dominica II classis for RG111(b) too, even though the FEAST, not the
Sunday, is observed. Before this fix an unrelated saint (Pope Sixtus II
et al., 6 August, Class3) was wrongly admitted into the freed slot on
every one of 1178 domain-wide days. Oracle-confirmed directly: 2023-08-06
(a Sunday) shows him displaced, commemorations empty; 2026-08-06 (an
ordinary Thursday) shows him admitted -- being a Sunday is exactly what
excludes him. admit now reads Sunday-ness off ~temporal (the day's own
temporal-cycle candidate, passed through from Precedence.resolve
unchanged) instead of observed. Validate's own admission fixed-point
invariant updated to pass the same real temporal candidate through.
Both golden pins in test_golden.ml were promoted from actual colitur day
output without independently consulting the rubric or the oracle first --
a real defect the review caught. Re-derived from both before re-pinning:
2028-08-06 and 2025-02-02 now pin comms=[], no commemoration at all,
matching missalemeum exactly in both cases.

Sunday uncommemorated
Caput III "De Dominicis", RG 16(a): a Feast of the Lord, I or II class,
occurring on a II-class Sunday takes the Sunday's own place with all its
rights and privileges -- of the Sunday, therefore, no commemoration is
made. band's entry 14 already ranked such a feast above the Sunday
correctly; disposition had no exception for the collision, so the impeded
Sunday fell through to the ordinary RG 95/109(a) commemorate-or-omit
catch-all and was wrongly admitted as a privileged commemoration.
Adds a branch to Rite_ef.Precedence_ef.disposition, gated on all four of:
loser is temporal-origin, loser rank Class2, loser carries the Sunday slug
marker, winner rank Class1-or-2 with subject Lord. No signature change --
disposition already receives the winner (RG 33's own vigil-omission branch
already reads it); each conjunct is proved independently load-bearing by
a dedicated disposition_cases row, including one real-data case each for
the winner's subject and rank conjuncts, and a defensive synthetic case
for the winner rank conjunct's currently-unreachable Class3 shape. A new
end-to-end resolve-level test (2028-08-06, the Transfiguration) proves the
real band/disposition pipeline together, checking the Omit reason string
distinguishes this from admit's own admission-limit cut.

precedence_ef.mli said "there is no fifth, unclassified case" after the
same commit renumbered the disposition list from four cases to five; the
count is now six.
precedence.mli's physical-equality obligation described the failure mode
as counting a drop "a SECOND time (once because it is genuinely absent,
once because its identity no longer matches)" -- the same condition
stated twice. What actually happens to a rebuilt candidate record is
that the celebration surfaces in BOTH commemorations (the copy) and
omitted (the original), one admission double-reported. precedence_ef.ml
carried the same muddled sentence, which is where the kernel's copy came
from; both now say it plainly.
vocab.ml/.mli referenced {!Rite_ef.rite_ef.ml} -- a filename inside an
odoc reference, which is malformed. Now plain [Rite_ef.rite].
README documented only `dune test`, so the exhaustive 1583-9999 Validate
sweep was discoverable only by reading test_validate.ml's own comment.
With no CI in this repo, that line is what stands between a committed
artifact and one anyone runs.
No behaviour change: `colitur day` output is byte-identical across 1583,
1900, 1902, 2008, 2011, 2026, 2038 and 9999 (2921 days, both domain
edges). 259 tests by default, 260 with the sweep.

Several comments described work as "arriving with Plan 3" or "waiting
for Plan 3" that either shipped without it or refer to the wrong future
plan number, all now false in ways that would mislead the next reader:
- temporal_ef.ml (two places) and precedence_ef.ml said the Major
Litanies (25 April, RG 80) "arrive with Plan 3's sanctoral". Plan 3
shipped, in this branch, without them; register §6 tracks this as a
plain open item with no plan committed to build it, and now says so.
- temporal_ef.ml said the Sacred Triduum's "own named offices are a Plan
3 sanctoral addition". Wrong on two counts: Plan 3 shipped without
adding them, AND a proper office for I-class FERIAS was never a
sanctoral matter in the first place (RG 21 defines "feria" to exclude
Sundays/feasts, not the reverse). 2026-04-02/03/04 still resolve to the
ordinary Passiontide ferial fallback's own generic slugs
(ef-passiontide-2-{thursday,friday,saturday}), confirmed against real
output; register §6 now records this as its own open item.
- temporal_ef.ml said the Rogation-Wednesday commemoration (Ascension
Vigil day, entry 21) "waits for RG 108-111" -- both the precedence
framework and RG 108-111 exist now; the Wednesday's own commemoration
is still never constructed, but for a different, still-real reason (no
candidate is wired for it), not a forward dependency. Fixed at both of
this comment's two occurrences in the file.
- vocab.ml/vocab.mli's `seasons` field doc said "Validate's contiguity
check reads this" -- false since validate.ml's "seasons" check switched
to Rite.t.season_runs in this branch (rite-supplied, to support a
season appearing in more than one run, which the modern form's Ordinary
Time needs and EF does not).
- vocab.ml/vocab.mli's `ranks` field doc said "it is not a precedence
relation until Plan 3 defines one" -- Plan 3 did define one (RG 111's
dignity ordering), but as its own small, separately-hardcoded function
in precedence_ef.ml, not one derived from this field; corrected to say
so precisely rather than leaving a forward-looking claim unresolved.
- The lectionary bootstrap (reading citations, Liturgical_day.t's own
`citations` field) is called "Plan 3" at slug.ml, vocab_ef.ml, and
three places in temporal_ef.ml, but "Plan 4" at liturgical_day.mli
(whose own doc comment -- "always empty until Plan 4" -- is the
authoritative one: the SANCTORAL bootstrap is Plan 3 and shipped; the
LECTIONARY bootstrap is a separate, later Plan 4). All six corrected to
say Plan 4, cross-referencing the Plan 3/4 distinction at the first
(slug.ml) occurrence so the reasoning is not duplicated six times.
No behaviour change: every edit here is a comment/documentation
correction. Verified byte-identical `colitur day` output across 1583,
1900, 1902, 2008, 2011, 2026, 2038, 9999. 259/259 tests green.

Six independent, small corrections found during the final review:
- dune (workspace root): the comment said the stanza used "(:standard)"
to preserve dune's default `default` alias target; the stanza actually
spells that out explicitly via (alias_rec install). Comment now matches
the code.
- test_validate.ml's test_easter_extremes asserted `List.length ys = 2`
where an identity check was called for -- the comment already named
1598 and 1666, but nothing confirmed extreme_years() found THOSE two
rather than some other pair with the right cardinality. Now asserts the
identities directly (the project's "cardinality where identity was
required" vacuity flavour, per the review).
- test_oracle.ml and expected-divergences-missalemeum.sexp both claimed
"one entry (M13) is [verdict open]" -- M11 is open too (its own verdict
changed from colitur to open in fix round 1); both now say "two entries
(M11 and M13)".
- expected-divergences-missalemeum.sexp's M2 note attributed `band` to
temporal_ef.ml; `band` is precedence_ef.ml's own function.
- lib/kernel/precedence.mli documented `dropped`/`admit`'s physical-
equality obligation nowhere -- it lived only in one rite's own module
(Rite_ef.Precedence_ef.admit's doc comment), but this signature is what
an author of the next rite actually reads. Added the obligation here,
cross-referencing the EF instance as precedent, not the only source.
- README's opam install line omitted sexplib and ppx_sexp_conv (both in
dune-project's own depends; `dune build` fails without them for a
contributor following the README verbatim) and documented only
`colitur easter`, though `temporal` and `day` both exist and are the
more useful entry points. Fixed both.
No behaviour change: comment/doc/test-assertion corrections only (the
easter-extremes fix strengthens an assertion, it does not change what
passes). Verified byte-identical `colitur day` output across 1583, 1900,
1902, 2008, 2011, 2026, 2038, 9999. 259/259 tests green.

68 "register line N" pointers in tracked code and data cited the
register's line numbers directly. The register has moved since: line 334
(cited six times as RG 91 entry 8) is now rose/colour prose; lines
375-376 (cited as "RG 109 leaves Advent/Lent Ember ordinary") are now
RG 26, the paragraph that refutes that exact reading; line 374 (cited as
RG 109(a)) is now RG 25's Latin; line 378 (RG 111) is blank.
expected-divergences.sexp even wrote "RG 91 line 332" three times, as
though the line offset were part of the rubric's own identity. Since
docs/research/rules-register.md is gitignored, no reader of the public
repo could resolve any of these, and -- since the register has moved on
its own copy too -- neither can the author's.
Replaced every pointer with an anchor that survives editing: the RG
paragraph/entry number itself (already present in nearly every case,
since the citation text already names "RG 91 entry N" or "RG 109(a)"
next to the stale line number -- the line number was redundant, not
load-bearing) plus a "§4" or quoted-subsection-heading pointer into the
register for readers who want to locate the fuller discussion. Also
corrected one genuinely stale content error found while migrating its
anchor: test_precedence_ef.ml's RG33 disposition-cases comment still said
"a I/II-class vigil impeded by any Sunday" -- the pre-Task-16
mistranscription the register itself corrects to II/III class; fixed the
prose alongside its citation, since leaving a wrong RG-class claim next
to a freshly-verified anchor would be worse than the stale line number it
replaced.
Covers lib/rites/rite_ef/precedence_ef.ml (18), precedence_ef.mli
(already fixed with item 1), test/test_precedence_ef.ml (44, including
two instances that only word-wrapped "register\nline N" across a line
break and so did not match a same-line grep), and
data/ef/expected-divergences.sexp (5, including three "RG 91 line 332"
instances). All 68 original pointers resolved -- none needed guessing;
every citation's target rule was already named in the surrounding prose.
No behaviour change: every edit is a comment/citation/data-note change.
Verified byte-identical `colitur day` output across 1583, 1900, 1902,
2008, 2011, 2026, 2038, 9999. 259/259 tests green.

Four citation problems, all resolved against the primary scans
(docs/research/*.pdf via pdftotext):
1. temporal_ef.ml's Ember-day date-derivation comment still carried a
retracted note claiming the scans have no numbered-paragraph statement
of the rule. Register §3a corrected this in an earlier commit (the
search used the genitive "Quatuor Temporum"; the rubric heading is the
nominative "Quatuor Tempora") and the register's own words warn "a
false 'not in the source' note is worse than no note" -- the code
still carried the retracted note verbatim. Replaced with the verified
citation and the primary Latin.
2. temporal_ef.ml cited RG 71 for "Advent I is the Sunday nearest 30
November". RG 71 is a season-boundary citation only ("a I Vesperis
dominicae I Adventus..."); it does not say which Sunday opens the
season. The actual rule is RG 20 (Caput III, "De Dominicis"):
"Dominica I Adventus ea est, quae cadit die 30 novembris vel est ipsi
proximior" -- verified against the scan and added to the register.
Behaviour was always correct; only the citation was borrowed.
3. RG 88 ("de Litaniis minoribus nihil fit in Officio") is cited five
times across code and tests, load-bearing twice (why Rogation days
take their season's ordinary ferial class; why privilege_of lets them
fall through to Ordinary), but appeared nowhere in the register. RG 67
and RG 69 were likewise cited at expected-divergences-missalemeum.sexp
(M11) without register backing. All three verified against the scan
and added to the register's §4 (Octaves / Rogations subsections).
4. Two citations flagged for re-verification, both CONFIRMED accurate
against the primary scan (word for word):
- precedence_ef.ml's RG 32 "si impeditur, commemoratur" (the sole
textual basis for treating a vigil as always-commemorated once RG 33
doesn't omit it outright) -- the register previously stated RG 32
only as "same pattern as RG 31", not verbatim; the full sentence is
now in the register too.
- precedence_ef.ml's RG 111(b) full sentence (the sole textual basis
for the shipped Sunday rank-floor fix) -- the register previously
carried only the fragment "de festo II classis"; the full sentence
is now there.
- temporal_ef.ml's RG 91 entry 7 "feria IV cinerum et II, III et IV
Hebdomadae sanctae" (the sole justification for stopping the I-class
ferias at Wednesday) was also checked and matches the scan exactly;
left as-is (already correctly cited), noted in the report.
Bonus finding while re-verifying RG 20: RG 17(d), same chapter, states
"festum D. N. Iesu Christi Regis, celebrandum dominica ultima mensis
octobris" -- primary-source confirmation that Christ the King falls on
the last Sunday of October. This was the register's one
oracle-backed-but-not-primary-verified rule (CLAUDE.md's own carried-item
language); it no longer is. Updated temporal_ef.ml's christ_the_king
comment and closed the item in register §6.
No behaviour change: every edit here is a comment/citation change to
already-correct code. Verified byte-identical `colitur day` output across
1583, 1900, 1902, 2008, 2011, 2026, 2038, 9999. 259/259 tests green.

The .mli's disposition doc still said a Class1-or-Class2 vigil is Omit
(RG 33) -- the pre-Task-16 mistranscription the register corrects at its
RG 33 entry. The .ml has read Class2 || Class3 since commit 079e332; the
.mli never caught up. It also named only vigil_suffix, when the vigil
test the code actually runs also checks vigil_prefix (the shape the
sanctoral bootstrap's four real vigils use); omitted RG 26's Class4
temporal-ferias-are-never-commemorated branch entirely, then asserted the
listed cases 'exhaust every representable shape', which was false as
written; and omitted RG 111(b)'s 'de festo II classis' rank floor from
admit's doc, describing only the privilege-override half of that rule.
Fixed all four: the vigil-omission bullet now names Class2/Class3 and
both slug conventions; the missing RG 26 branch is now documented,
folding the exhaustiveness claim into an accurate five-branch count;
admit's Sunday case now states the rank floor as a second, independent
condition.
The same stale RG 109(e) reading this interface carried ('leaves the
Advent and Lent Ember sets ordinary') also survived as the stated reason
september_ember_prefix exists, in the .ml, about 330 lines from the
already-corrected privilege_of comment it contradicts. Fixed there too:
September is broken out because it sits outside RG 109(e)'s three named
seasons entirely, not because Advent/Lent Ember needs excluding from (e)
-- it does not, per privilege_of's own corrected comment.
No behaviour change: both fixes are doc-comment-only edits to already-
correct code (precedence_ef.ml's disposition/admit implementations were
fixed in an earlier commit; only the .mli's prose and one earlier .ml
comment lagged).

RG109
Review round 1 (F1, Critical): the commemoration-eligibility fix from
the previous commit silently dropped II-class Advent and Lent Ember
ferias when impeded, while ordinary (lower-solemnity) ferias of the
same seasons kept their commemoration -- backwards on any reading.
Reproduced: 1900-12-21 (an Advent Ember Friday) lost its commemoration
entirely; 2026-12-21 (an ordinary Advent feria the same week) kept
its.
F2 (Important, the direct cause of F1): the branch's own justification
mis-stated RG 109 as an exhaustive list of the only temporal
circumstances that generate a commemoration. RG 109 is headed
"Commemorationes privilegiatae sunt commemorationes" and closes
"Omnes aliae commemorationes sunt commemorationes ordinariae" -- it
sorts commemorations that already exist into two HONOUR classes
(RG 108's differing liturgical hours), and says nothing about which
offices have the right to be commemorated at all. That right belongs
to Caput IV, "De feriis" (RG 21-27), never opened by the original
pass:
RG 24 (II-class ferias): "si vero impediuntur, commemorari debent"
-- if impeded, MUST be commemorated. Not optional.
RG 25 (III-class ferias): same mandate.
RG 26: every feria not named in 23-25 is IV class, and IV-class
ferias are NEVER commemorated -- the one exclusion RG 21-27 actually
states.
The omission branch is now gated on `rank = Class4` (RG 26) directly,
not on `privilege_of = Ordinary` -- the old gate happened to reach the
right answer for IV-class ferias (RG 26 also excludes them, for a
reason the old citation did not give) and the wrong one for II/III-
class Ember ferias RG 109(e) did not name by letter.
RG 109(e) itself is also corrected: its bare "feriis Adventus,
Quadragesimae et Passionis" previously excluded the Advent and Lent
Ember sub-days by analogy with (d)'s separate September carve-out.
RG 91's own TABLE needs an explicit "exceptis feriis Quatuor
Temporum" at entries 22 and 25 to keep Ember days from being double-
listed against their own entry 18 -- an exception that would be
unnecessary drafting if "feriae Adventus"/"feriae Quadragesimae" did
not already include their Ember sub-days by default. RG 109(e) carries
no such exception, so it is read at that same default, inclusive
scope: the Advent and Lent Ember ferias are privileged under (e), not
merely ordinary-but-commemorable. (d)'s own existence is unaffected --
September Ember days sit outside Advent/Lent/Passiontide under any
reading, so (d) remains necessary regardless.
Verified: 1900-12-21 and 1902-02-22 now correctly commemorate their
Ember ferias; 2026-12-21 and 1902-02-24 (ordinary ferias) unchanged.
Blast radius re-measured against the prior commit, 1900-2100: 102
civil days changed, every one an Advent/Lent Ember (or Ember-vs-
Joseph-collision) day regaining its commemoration, nothing else.
Validate re-swept exhaustively, 1583-9998: 0 failures.
F6: two privilege-boundary test rows that had been bent to expect the
bug's own output (Commemorate -> Omit) are restored to what RG 24/25
actually require, now Commemorate(Privileged) given the RG 109(e)
correction above -- these are the rows that should have caught F1.
F7: admit_cases had no witness for RG 111(b)'s rank floor that wasn't
already Class2, so reverting that filter only reddened the oracle
suite, never this file. Added a row (II-class Sunday, sole candidate
an ordinary Class3) that fails without the filter and passes with it.
F9: RG 122 cited alongside RG 128(b) for Holy Thursday's white --
states the same fact affirmatively ("Demum adhibetur color albus,
feria V Hebdomadae sanctae...") rather than as an exception to violet.

RG 128(b) excepts "Missa sive Chrismatis sive in Cena Domini feria V
Hebdomadae sanctae" from the Septuagesima-to-Easter-Vigil violet span
as a whole-Mass exception (unlike Palm Sunday's blessing/procession,
which the same sentence carves out as only part of that day) -- so
Holy Thursday's Mass is white, not violet. temporal_ef.ml fell through
to the generic Passiontide ferial path (season_colour Passiontide =
violet) for this date, since [named] has no entry for the Triduum at
all (rank was already correct via [privileged_feria]; only colour was
wrong).
Found via Task 16's missalemeum oracle comparison: every other Triduum
day's oracle colour set includes violet as an option (Good Friday
"bv", Holy Saturday "vw" -- already-flagged, deliberately deferred
per-action gaps, register §3b), but Holy Thursday's is white alone.
This is a genuine NEW divergence from lectio too (lectio has no such
exception and still prints violet for Holy Thursday) -- added as
Layer C11 to the differential harness and data/ef/expected-divergences
.sexp, 46 rows (2005-2050), rather than silently changing what that
harness accepts.
Also corrected a stale comment on season_colour claiming white's RG
paragraph was never pinned -- RG 119 was found and cited in the
register on 2026-08-11 but the correction was never copied into this
file's own comment.

Task 16's missalemeum oracle comparison (2026-2027) surfaced three
distinct precedence-engine bugs, each confirmed against the primary
1962 Missale Romanum text and cross-checked against the oracle:
1. RG 33 (vigil omission) was transcribed backwards. The primary text
reads "Vigilia II AUT III classis penitus omittitur" (a II OR III
class vigil is entirely omitted on any Sunday or I-class feast) --
not "I aut II" as the register and this module's own rank check
(Class1 || Class2) previously had it. I-class vigils (Nativity,
Pentecost) can never actually lose in this engine (band always
ranks them above anything that could coincide with their dates), so
the Class1 half was dead code; the real bug was that Class3 (St
Lawrence's vigil, the sole III-class vigil) was MISSING, so it fell
through to an ordinary commemoration instead of RG 33's mandatory
omission whenever 9 August landed on a Sunday.
2. RG 93/95/109/113 read together: an ordinary, non-privileged
TEMPORAL-cycle office (a bog-standard green-season feria, a plain
Advent/Lent Ember day, a Minor Rogation day) has no standing to be
commemorated at all when impeded -- RG 109's six-item list is a
CLOSED set of the only temporal circumstances that generate a
commemoration, not a floor under which anything ordinary still
gets one. The engine previously commemorated the losing feria
itself in this situation; confirmed wrong against ~190 independent
missalemeum days (2026-2027) showing zero commemorations for the
exact shape. Vigils are explicitly excluded from this new rule --
RG 31/32 give them their own "if impeded, commemorated" mandate,
independent of RG 109's list.
3. RG 111(b)'s Sunday admission slot is restricted to "de festo II
classis" -- a rank restriction, not merely the best available
ordinary candidate. A III/IV-class ordinary saint competing for a
II-class Sunday's single commemoration slot had no such restriction
applied before; confirmed wrong via St Hyginus (11 Jan, Class3)
losing to Holy Family, which missalemeum shows entirely displaced,
never commemorated.
All three fixes are pure disposition/admission changes -- they never
touch band, so the observed day (season/slug/rank/colour) is
unaffected in every case; the lectio differential (which never
compares commemorations) stays green untouched. test_precedence_ef.ml
updated throughout: two previously-wrong test expectations corrected
(the RG33 III-class-vigil boundary row, the IV-class-feria totality
row), three privilege boundary rows sharpened from "commemorated but
unprivileged" to "omitted entirely" now that temporal+ordinary
means omission, and a new contrast row added to keep the SANCTORAL
side of rule 2 covered separately from the TEMPORAL side.

Three carried items from Plan 2's parked rulings, closed:
1. Slug uniqueness moves from a 200-sample QCheck property scoped to
one rite (test_temporal_ef.ml) into Validate's own "slugs" check, so
every consumer gets it. The resumed-Sunday exemption that property
carried is dropped, not weakened elsewhere: Plan 2 verified zero
duplicate slugs domain-wide (all 8 416 years), and by construction a
resumed Sunday only ever backfills a week number Septuagesima cut
short that same liturgical year, so it can never repeat a number
that year's own January Sundays already used. The now-redundant
property and its is_resumable_sunday_slug helper are removed from
test_temporal_ef.ml; test_validate.ml's own domain-wide property
covers the same ground for every consumer.
2. The anchors-erosion guard (Plan 2: deleting entries from a rite's
anchors list left the whole suite green) is implemented, but not in
Validate. Which of a rite's named days are Easter-derived is
knowledge only the rite's own `named` function has; Rite.t
deliberately exposes only `temporal` and `anchors`, never `named`,
so a rite-agnostic Validate has no ground truth to check anchors'
completeness against. Hardcoding an Easter offset, or even Easter
itself, would smuggle Western/Gregorian-specific knowledge into code
meant to also serve a future Julian-reckoning rite; rediscovering
"named-ness" structurally from `temporal` alone is unsound for EF,
since most ordinary Sunday/feria slugs from Septuagesima onward are
also constant-offset-from-Easter by construction. The guard is
therefore EF-specific and lives in test_temporal_ef.ml, discovering
the Easter-derived slug set mechanically (scanning a window around
Easter and keeping whatever `named` answers Some for) rather than
hand-copying either named's or anchors' own offset list, then
asserting completeness against the real anchors for the domain's
Easter extremes (1598, 1666) plus an ordinary year. A negative
fixture proves the guard has teeth, matching Plan 2's exact
regression (anchors missing "ef-ascension" reports it, and only it,
as missing).
3. test_validate.ml's extreme_years comment claimed 1818/2038; verified
against Computus.gregorian_easter directly, the domain's actual
Easter extremes (1583..2500) are 1598/1666. Corrected.
Verification: the full 1583..9999 domain sweep (233 tests via dune
test's 200-sample default, plus a manual full sweep) reports exactly
one failure -- the known, already-pinned year-9999 season-truncation
case -- and zero occurrences of the new "slugs" check anywhere in the
domain. Deleting "ef-ascension" from the real anchors list (reproducing
Plan 2's regression directly) is caught immediately by the new EF test
and, confirmed empirically, invisible to Validate's own full property
sweep -- direct evidence for why item 2 cannot live in Validate.

Widen Validate.run to take the rite's sanctoral layer alongside the rite
itself (Calendar.year needs both), and add five checks over the fully
resolved liturgical year, on top of the existing temporal-only pass:
- observed: a day's observed celebration never also appears among that
same day's own commemorations/omissions.
- lost: no sanctoral entry is silently dropped. Per slug, the number of
times it is actually sighted (observed + commemorations + omitted,
summed over the year) must never fall below the number of times its
own Date_spec resolves within the year's span -- also fires if
resolving the year raises at all, the most total form of loss.
- duplicated: the same per-slug count must never exceed the number of
Date_spec resolutions either. Deliberately NOT "no slug appears
twice": a fixed date can legitimately resolve twice in the ~20% of
liturgical years whose 371-day span reaches it on both ends (30
November/St Andrew is the worked example in validate.mli).
- unconverged: no day's omitted reason indicates Calendar's placement
pass hit its round guard before reaching a fixed point.
- admission: the rite's own rules.admit is a fixed point on what it
already admitted -- the rite-agnostic form of "the admission limit
was not exceeded" available without embedding a rite's own numeric
caps (RG 111's, for EF) into kernel code.
Each check has a dedicated negative fixture in the synthetic rite
(test_validate.ml), hand-traced against Calendar's actual resolution
mechanics before writing the assertion, and verified to fail for the
right reason against the code before this change. One pair
(unconverged/duplicated) is not fully independent: hitting the round
guard genuinely also trips duplicated, a real consequence of Calendar's
own accounting once a candidate is simultaneously sighted at its
permanent natural date and wherever the last placement round left it --
documented in guard_rules's own comment, not papered over.
test_validate.ml's ef_rite/run now use the real Rite_ef.context and the
real bootstrapped data/ef layer (Precedence_ef and the sanctoral
bootstrap did not exist when this scaffolding was first written) rather
than the earlier placeholder rules. Validate is clean across the whole
1583..9999 domain against real EF data except the one already-documented
year-9999 truncation case (test_year_9999_does_not_raise).
