* feat(ef): the Mass preface, RG 482-499Lukasz Kasprzak2026-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Item 2 of Phase 3 (celebrant-rubrics-phase1), the bulk of this phase and the last EF Mass rubric this project scoped: which preface is said, deferring to seasonal/proper-title rules for the fourteen named prefaces, then RG 498's Common residual. RG 482 gives the resolution chain: the Mass's own proper preface, failing that the seasonal one, failing that Common. Read literally, RG 484-497 look like fourteen separate rules, but each numbered rubric's own propria/de-Tempore pair produces the SAME preface identity either way, so the whole chain collapses into one priority- ordered decision: title/mystery triggers (Holy Cross, Sacred Heart, Christ the King, Trinity, St Joseph, BVM, the Nativity octave, the Apostles, Epiphany), each independent of season, then six seasonal windows (Nativity, Epiphany, Lent, Holy Cross/Passiontide, Easter, Ascension, Holy Spirit, Trinity-for-ordinary-Sundays), then Common. The "one genuinely unproven piece" the design spec worried about -- per-feast proper prefaces extracted from the Missal's propers at scale -- turned out not to be a large-scale extraction problem at all: every one of the fourteen propers is a closed, small, subject/slug-keyed trigger (mirroring Precedence_ef.band's own RG 91 table), not thousands of individual saints' pages. The one genuine open question (RG 488, the Chrism Mass) is N/A: this engine resolves one Mass per civil day and has no separate Chrism-Mass dimension. Preface is a new kernel type (lib/kernel/preface.ml[i]), not an EF-specific one, the same placement as Colour/Subject/Mass_formulary: Liturgical_day.t is parameterised only over season/rank, so any field it carries generically must live in the kernel even though only EF constructs a value of it today. Wired exactly as creed/gloria were (Rite.t.preface, Calendar.ml, Rite_ef.context), but Preface.t option, not a bare bool: unlike creed/gloria, a preface is said only at a Mass, and Good Friday (1955-restored Holy Week) resolves an observed celebration but has no Mass at all -- None is the honest answer there, and also the neutral value an unimplemented rite returns. Two priority-order findings only the oracle settled, not derivable from the Latin text in isolation, both cross-checked against 358 individually classified entries in the FIUV Ordo's own praef column (test/fixtures/fiuv-ordo-2025-2026.sexp, already captured, wired up here as a new comparison axis): RG 484(b)'s own "except Masses with a proper of the divine mysteries or Persons" is narrower than every other window's implicit exception (an Apostle inside the Nativity octave is overridden to Nativity; outside it, keeps his own preface even inside another window); and RG 495's "et votivis" half is live for the one office this engine models without a votive-Mass dimension (the Saturday Office of the BVM), which also proved a vigil is not a "festum" for this purpose (the Assumption's own vigil takes Common, not BVM, correcting an initial reuse of Precedence_ef.marian_slugs that had no reason to make that distinction for its own, different rubric). A third, RG16(a)-shaped fix landed the same way: RG 494(b)'s own Trinity grant must read the day's TEMPORAL season, not the celebration that actually won it, or a Class1 feast with no preference of its own (All Saints) wrongly falls to Common on a Sunday it merely commemorates. colitur rubrics gains a sixth TAB-separated column. Domain-wide 1583-9999 exhaustive sweep confirms every Christmastide day resolves Nativity/Epiphany/Bvm, every Paschaltide day one of its own three windows or a season-independent title, every Lent day Lent or a title, and Passiontide legitimately produces Easter exactly once a year (the Vigil Mass) -- 8416 of the domain's 8417 years, the one short year being the domain's own upper boundary (the liturgical year opening in 9999 cannot construct dates in year 10000, a pre-existing edge this sweep re-confirms rather than a new one). day/readings verified byte-identical to the branch's own state before this phase (commit 9c96e0a) across a 455-year sample spanning the whole domain -- not literally to the v0.10.1 tag, which 22 earlier commits on this same branch (Phase 1/2, the bissextile shift, the Rogation colour fix) had already moved past before this phase began.
* feat(ef): the Gloria in excelsis, RG 431-432, deferring to Breviary 237-238Lukasz Kasprzak2026-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Phase 2 of celebrant-rubrics-phase1: colitur rubrics gains a fifth column, whether the Gloria is said. Follows the Creed's own seam exactly -- Rite.t.gloria, Liturgical_day.t.gloria, wired through calendar.ml the same way. RG 431(a)/432(a) defer the Gloria to the Breviary's own Te Deum rule (nn. 237-238), so te_deum is implemented as its own named predicate, cited clause by clause, not collapsed into a colour heuristic. 431(c) (Holy Thursday, the Easter Vigil Mass) and 432(b)/(d) (violet; a Requiem) are independent overrides checked ahead of the Te Deum-derived answer. Every clause this engine has no dimension to model (votive Mass classes, the wider n.302 "Missa festiva" categories) is stated as N/A with its own reasoning, not silently dropped. Validated against the FIUV universal Ordo (Gloria and Te Deum) and all three LMS editions (Gloria). A first pass over-trusted a clean-looking 15-for-15 FIUV contradiction of 237(b)'s own Septuagesima exception and replaced it with a blanket "every Sunday" rule; the evidence was itself corrupted -- the FIUV extractor recognised only one of the source's two Te Deum negations ("non dicitur", not "sine"), so every "sine Te Deum" Sunday read wrongly true. Fixed in tools/extract_fiuv_ordo.ml, fixture re-extracted, and the literal 237(b) reading restored once the corrected data confirmed it. A second bug surfaced alongside it (Palm/ Passion Sunday wrongly reading true via Temporal_ef.named's own table membership, then Christ the King wrongly reading false from an over-broad fix) is closed with an explicit two-slug exclusion. Domain-wide 1583-9999: every violet or Rose day is gloria=false except the Easter Vigil (RG 431(c) lex specialis), every Requiem is gloria=false, both measured exhaustively, zero exceptions. Mutation- proved: disabling 431(c) reddens 8 tests including all four oracle comparisons; disabling 238(c)'s feria-I-classis exclusion reddens exactly the dedicated Ash Wednesday unit test, a genuine blind spot in both oracle layers, reported rather than hidden. Two open, cited findings, neither fixed here (out of this task's "follow creed's exact seam" scope): a privileged Lenten/Passiontide feria carrying one commemoration reads Gloria=true in the LMS Ordo but Te-Deum=true/Gloria=false in FIUV -- the two oracles disagree with each other, not merely with colitur (data/ef/expected-divergences-lms.sexp L5, expected-divergences-fiuv.sexp F3); and a pre-existing, uncited Colour.Violet bug on Rogation Monday/Tuesday in Temporal_ef.temporal, surfaced by this comparison but root-caused as a separate defect (L6). day/readings verified byte-identical against a build from the branch tip before this task (v0.10.1's own tag predates an already-landed bissextile fix that legitimately changed both, so it is not the right baseline). 671 tests green (dune test); 678 with the exhaustive sweep (COLITUR_EXHAUSTIVE_SWEEP=1 dune test --force, ~104s).
* feat(ef): the Creed, RG 475-476Lukasz Kasprzak2026-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whether the Creed is said at Mass. New Rubrics_ef.creed, reached through a new Rite.t.creed field and a new Liturgical_day.t.creed bool (false, not an option, for a rite that has not implemented the rule); colitur rubrics gains a fourth TAB-separated column. 475(a) reads the TEMPORAL cycle's own weekday, not the observed day: a Sunday impeded by a Feast of the Lord (RG 16a) still says the Creed. 475(d)'s three octaves (Nativity, Easter, Pentecost) are pure date/ Easter-offset windows, checked first, since a saint's feast winning the day inside one of them still says the Creed ("etiam in festis occurrentibus") -- St Stephen, 26 December, is the live witness. RG 23 classifies Ash Wednesday and every feria of Holy Week (including the Sacred Triduum) as feriae, not festa, however high their rank, so 475(b)/(c)'s "in festis" never reaches them; this single check subsumes 476(a)'s own naming of the Chrism/Lord's-Supper Mass and the Easter Vigil. RG 28-34 vigils are a third liturgical-day category, also excluded from "in festis" regardless of rank -- reuses the already- exported Precedence_ef.is_vigil rather than a new list. 475(e)'s Apostle/Evangelist natalicia list (creed_apostle_slugs) was derived by grepping data/ef/sanctoral.sexp directly and checking each candidate's own date against whether it is that saint's dies natalis -- not copied from any list supplied with the task. The Conversion of St Paul and the 30 June Commemoration of St Paul are excluded (neither is a natalicium); the Chair of St Peter and St Barnabas are included only because the clause names them explicitly, which is exactly why it has to: neither is a natalicium either. 475(c)'s BVM half reuses Precedence_ef.marian_slugs (newly exported) rather than the subject field alone: checked against the shipped data, almost every Marian sanctoral entry ships subject=Saint, not Bvm. man/colitur.1's rubrics section is updated to match the new column; test/cli.t repinned via dune promote for the same reason. Verified day/readings output byte-identical to v0.10.1 across the whole 1583-9999 domain (both binaries' concatenated day+readings output, 6,148,492 lines each, zero diff). Domain-wide: 882,996 days say the Creed, 2,191,250 do not; every one of the domain's 439,178 Sundays says it, zero exceptions.
* feat(kernel,ef): the lectionary reports which Mass it saidLukasz Kasprzak2026-08-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rite.readings now returns (Mass_formulary.t option * Citation.t list) instead of a bare citation list, and Liturgical_day.t carries the result as a new formulary field. Validate holds a rite that resolves a formulary at all to resolving one on every day, the same discipline it already applies to citations; the EF lectionary chain resolves Some on every day of every year 1583-9999, confirmed by a direct sweep over 2005-2050 as well as through Validate itself. Plan Tasks 2 and 3 are merged into this one commit on the coordinator's own instruction: Rite.readings' signature and the field that consumes it are one atomic edit, and the intermediate state does not compile on its own. Each of the four lectionary steps now builds its own Mass_formulary.t at the point it decides, not by re-deriving it afterwards from the citations it returns: step 1 tags Proper with the observed slug, step 2 tags Own_slug with the day's own temporal slug, step 3 tags Preceding_sunday with the resumed Sunday's temporal slug, and step 4 tags Common with the Common's own id -- Commons.find now returns that id alongside its citations rather than discarding it, since it is only ever in scope at the point the assignment is looked up. The RG 309(a) Saturday votive Mass of Our Lady, which answers between steps 4 and 2 rather than as one of the four numbered steps, is tagged Own_slug too: Mass_formulary.source has no dedicated constructor for it, and its own guard only ever fires when the observed celebration already is the day's own (reused ferial) temporal slug, which is exactly what Own_slug documents. Recorded as a judgement call in the task report, not a specified answer. test/cli.t's `emit --format sexp` line count is repinned (8472 to 8881): that command serializes Liturgical_day.t whole, so the new field grows its output. `colitur day` itself is untouched -- verified byte-identical against the pre-change binary across 1583, 1900, 2026, 2038 and 9999.
* kernel(calendar): fix multi-departure loss, band-order gap, off-array targetsLukasz Kasprzak2026-08-111-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Four findings from Task 6 review, addressed on top of f15e44d. 1. transferred_out was a single Date.t option, so when RG 97-98 collides three or more feasts on one date (more than one loser), only the last one Hashtbl.iter happened to visit survived -- a genuinely lost move, and which one survived depended on OCaml's hash seed (OCAMLRUNPARAM=R), an environment read a kernel invariant forbids. RG 97-98 says coinciding feasts transfer "in order" -- plural -- so the type was wrong, not the fixture: transferred_out is now (Celebration.t * Date.t) list. transferred_in stays a single option, deliberately: a day receives at most one arrival (RG 96 sends each departure to the next non-I/II-class day, and the first to arrive occupies it). The per-day list is canonicalised (sorted by target date, then slug) after accumulation, the same fix layer.ml already applies to its own date-bucket index and for the same reason. Verified clean across 15 runs under OCAMLRUNPARAM=R; disabling the canonicalisation step showed the raw order genuinely flip between seeds, confirming the fix is load-bearing. 2. Every deferred candidate in the fixture was the same rank, so compare_deferred's band branch was unreachable and reversing it broke nothing -- the RG 97-98 test was pinning slug order, not band order. The fixture now has three ranks (Hi1 outranks Hi2, both transfer, both outrank Lo), with slugs chosen so band order and slug order disagree. Reversing the band comparison now fails the test on "higher-band loser claims 2 Feb first", received the wrong slug instead. 3. A transfer_target free to name any date could place a candidate outside the liturgical year's own start/stop bounds: invisible to year/build_day, so it would be observed nowhere and, since its origin's re-resolution would report it as settled, omitted nowhere either -- genuinely gone, contradicting calendar.mli's "never silently dropped". place_transfers now checks the range on every placement and routes an out-of-range one to a permanent-exclusion table instead of assignment, with its own cited omitted reason. 4. Precedence.resolve folds Transfer and Repose into one deferred case, and place_transfers routed all of it through transfer_target (RG 96's search), which is only correct for Transfer. Repose is RG 100-102's repositio, a distinct rubric this module does not implement. Documented rather than split into a second mechanism: nothing in the EF ruleset returns Repose (design spec section 1.3, "declared, not exercised"), so the gap is latent, not a live bug. Two new tests (origin records every departure; transfer target outside year is recorded not lost); the RG 97-98 test's fixture and assertions rewritten for finding 2.
* kernel: carry omitted celebrations on Liturgical_day.t, reason and allLukasz Kasprzak2026-08-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Precedence.resolution already tracked what happened to every losing candidate -- commemorated, deferred, or omitted with a reason -- but Liturgical_day.t had nowhere for the deferred and omitted buckets to land, so Calendar dropped them at the door. Task 12's no-celebration-lost invariant needs to read that accounting off the day result itself, not re-resolve every day to reconstruct it, so a reason recorded nowhere is not recorded. Add Liturgical_day.omitted : ('r Celebration.t * string) list, after transferred_out and before citations. Calendar.resolve_day now folds resolution.omitted (Precedence's own native omissions, reasons intact) and resolution.deferred (mapped to "deferred: transfer placement not yet implemented (Task 6)") into it. Adds a full-day accounting test against the whole Calendar pipeline: four colliding sanctoral entries plus the day's feria, checked as a slug set (matching test_precedence.ml's own nothing-silently-lost test) so a candidate silently dropped or duplicated into two buckets would fail it, plus an identity check that the deferred and admission-limit reasons don't get swapped.
* kernel: the LiturgicalDay result schemaLukasz Kasprzak2026-08-111-0/+19
Temporal is embedded rather than flattened, so season/week/weekday have one home and cannot disagree with themselves. transferred_in/out make transfers visible in the result -- an ordo must print 'transferred from the 25th', and the nothing-lost invariant reads these fields. citations exists and is empty until Plan 4; adding it later would widen a type every consumer matches on.
