* rite(ef): clamp the RG96 search at the domain ceilingLukasz Kasprzak2026-08-121-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | search_from could walk up to 400 days past origin before Calendar's own ~start ~stop clamp is ever consulted, and nothing stopped it probing occupant on a date past 31 December 9999 -- occupant chains through the real EF rite's temporal, which calls Computus.gregorian_easter, not total outside 1583..9999 (it Date.makes and failwiths on Error). Not reachable with the shipped sanctoral data alone, but reachable through the project's own primary extension path: an overlay adding an I-class feast on 25 December leaves nothing but Class2 Nativity-octave days for the rest of civil year 9999, so the unguarded search reached 1 January of year 10000 and crashed there with 'computus: year 10000 out of range 1583..9999'. 9999 is an in-range year and the kernel's contract is 'never raises on in-range input'. search_from now also stops, without probing occupant again, once it passes Date's own domain ceiling -- the same 'return a finite date, let Calendar's own out-of-range handling record it, never pretend to have found something admissible' contract the existing step-count guard already follows. Two new tests, both mutation-verified to actually reproduce the crash when the guard is removed (see the task report): a precedence_ef.ml unit test using the real Temporal_ef.temporal as occupant (a synthetic occupant can never discriminate this, since it never calls Computus itself), and a Calendar-level integration test reproducing the exact overlay-based scenario the review found.
* cli: colitur day <year> dumps resolved liturgical daysLukasz Kasprzak2026-08-121-1/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assembles Rite_ef.context (lib/rites/rite_ef/rite_ef.ml[i]): temporal, anchors and vocab from Temporal_ef; rules from Precedence_ef's band, disposition and admit; season_runs = Vocab_ef.seasons; transfer_target newly implemented here. transfer_target (RG 96): the next following day that is not I or II class, with the Annunciation's own exception (Monday after Low Sunday). Terminates by a structural step bound on its internal search, independent of Calendar's own round guard, which bounds rounds across a year, not one call's walk; documented as an obligation on rite.mli's transfer_target field, which did not previously state it. Fixes the vigil-naming mismatch Task 7's review predicted: the sanctoral bootstrap names its vigils with a vigil-of-X prefix (lectio's own convention), while Precedence_ef's is_vigil only recognised the temporal cycle's own X-vigil suffix. Both are now recognised, fixing RG 91 entries 21/26 and RG 33's vigil omission for the four affected celebrations. Verified by unit test and by mutation-testing the fix (reverting it fails exactly the new rows) and against real output across several years. Suppresses data/ef/sanctoral.sexp's vigil-of-christmas via a new overlay, data/ef/adjustments.sexp: it is the same celebration as the temporal cycle's own ef-nativity-vigil, both dated 24 December. colitur day <year>: one line per civil-year day, temporal and sanctoral fully resolved through Layer, Overlay, Precedence_ef and Calendar -- the first CLI path exercising the whole Plan 3 pipeline against real data. Verified the All Souls transfer chain (Tasks 7-8-11) end to end against real output for both a Sunday year (2025, lands on 3 Nov) and a non-Sunday year (2026, observed directly on 2 Nov).
* test(ef): prove the II-class-Sunday privilege override end-to-endLukasz Kasprzak2026-08-111-1/+67
| | | | | | | | | | | | | | | | | | | | | | | | | Adds test_ii_class_sunday_privileged_witness_admitted_end_to_end, proving RG 111's "II-class Sundays: one, dropped if a privileged one is due" clause through the real pipeline (band, disposition, privilege_of, admit together), not only at the isolated admit level. RG 109(b) is the one privileged category that is sanctoral and rank-based rather than temporal-origin: a Commemoration_only, Class1 sanctoral candidate (the same shape disposition_cases already uses as (b)'s witness) is held out of the band contest entirely by Precedence.resolve, so it always loses regardless of what wins the day. Paired with an ordinary sanctoral saint, both losing to an ordinary Class2 Sunday, gives observed_is_sunday = true with one privileged and one ordinary loser due at once, with no new fixture. Documents, and mutation-confirms, what this fixture does and does not prove: RG 109(b)'s only reachable witness is Class1 (the highest dignity), so the privileged loser here is unavoidably also the higher-dignity one, and the admission outcome alone cannot distinguish "privilege overrides dignity" from "dignity alone picked the same winner" -- that distinction remains admit_cases's job. What this test does prove, and what a category-(b) regression in privilege_of breaks, is the privilege tag itself surviving the real pipeline end-to-end.
* rite(ef): an impeded I-class Sunday commemorates, not transfersLukasz Kasprzak2026-08-111-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | disposition's Class1 branch was unconditional on rank, so an impeded I-class Sunday (Advent/Lent/Passiontide/Low Sunday) currently transferred like a feast. RG 95 (register lines 323, 363) restricts the right of translation to I-class FEASTS -- RG 91's own table lists Sundays as a separate row (entry 6, line 332) from feasts (entries 11-13, lines 337-339) -- and RG 109(a) (line 374) lists "of a Sunday" as a privileged commemoration category, which presupposes an impeded Sunday stays put rather than moving to another day. Excludes is_sunday_slug losers from the Transfer branch so they fall through to the existing Commemorate (privilege_of loser) branch, which already tags them Privileged via RG 109(a) with no further change. Fires on real dates in the 2005-2050 differential window: 24 December on Advent IV in 2023, 2028, 2034, 2045; 8 December on an Advent Sunday in 2024, 2030, 2041. Verified no previously-passing Transfer assertion used a Sunday-shaped loser (grepped test_precedence_ef.ml, test_calendar.ml -- which uses its own synthetic rite unrelated to Precedence_ef.disposition -- test_colitur.ml, test_validate.ml); confirmed by mutation-reverting the fix and observing exactly the one new test fail, nothing else.
* rite(ef): commemoration privilege and admission (RG 108-111)Lukasz Kasprzak2026-08-111-4/+306
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Precedence_ef.privilege_of classifies a commemoration candidate against RG 109's closed list of privileged commemorations (a Sunday; a I-class day; a day within the Octave of the Nativity; a September Ember day; a feria of Advent, Lent or Passiontide; the Major Rogations in Mass), read entirely off the candidate's own rank/slug/origin, no context needed. Major Rogations (f) is left unimplemented rather than guessed: no producer for the Major Litanies exists anywhere in this codebase yet. disposition's two Commemorate sites now call privilege_of instead of Task 8's interim_privilege placeholder, which is removed entirely (binding and .mli export both gone). Precedence_ef.admit applies RG 111's four admission counts, keyed on the observed day's own class and Sunday-ness: a I-class day admits none except one privileged commemoration; a II-class Sunday admits one, but a privileged commemoration due displaces any ordinary one regardless of dignity; any other II-class day admits one by dignity alone, with no such override; III/IV-class days admit at most two by dignity. Ties break on slug, matching Precedence.compare_by, so the admitted set never depends on input order. Every admitted candidate is a value taken unchanged from the input list, never rebuilt, so Precedence.resolve's physical-equality-based dropped/omitted accounting keeps working -- closing a note left open since Task 2. Tests: RG 109 category rows (one per reachable category, plus boundary rows proving Advent/Lent Ember days and Minor Rogations are correctly excluded), RG 111 admission rows checked on slug identity rather than count, an order-independence check, and three end-to-end integration tests proving the admission limit's drop lands in resolution.omitted rather than vanishing.
* rite(ef): occurrence dispositions (RG 92-95, 33, 94)Lukasz Kasprzak2026-08-111-4/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Precedence_ef.disposition decides the loser's fate in an occurrence: a Commemoration_only celebration is always commemorated (it can never win or transfer); a I- or II-class vigil impeded by any Sunday or a I-class feast is entirely omitted (RG 33), checked before the generic rule below or the Nativity/Pentecost Vigil could wrongly transfer; any other I-class loser transfers (RG 95 -- only I class has the right of translation); everything else is commemorated, with the admit-or-omit decision left to RG 108-111's admission count (Task 9). RG 94 needs no code: resolve always compares a loser against the day's actual winner, never against a departed sibling, so no commemoration can ride along with a transferred feast in this design. This is the branch that completes Task 7's carried All Souls fix: once it loses to an occurring Sunday, its untouched Class1 rank routes it to Transfer via the generic rule, not a special case. Landing on 3 November is Rite.transfer_target's job, not wired up yet. Commemorate carries an interim Precedence.Ordinary privilege pending Task 9's RG 109 implementation, exposed as interim_privilege for that task to replace. Table-driven tests cover each rule, including RG 33's boundary from both sides and a Commemoration_only loser that is also Class1 and vigil-shaped to pin the branch ordering. Mutation-tested: disabling RG 33, either direction of RG 95's rank condition, or the Commemoration_only priority check each fail exactly the rows built to catch them.
* rite(ef): fix entry 8's Sunday exception and entry 14's over-restrictionLukasz Kasprzak2026-08-111-6/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Review of 436ba75 found two calendar defects and one coupling risk. Entry 8 (All Souls) dropped register line 334's own qualifier, "(yields to an occurring Sunday)" -- it returned 8 unconditionally, so on 2 November falling on a Sunday (2025, 2031, 2036, 2042 in the 2005-2050 differential window), All Souls incorrectly outranked and observed over the Sunday. 2 November is always Time_after_pentecost and never coincides with any other entry's own date, so the only rival this exception ever has is an ordinary entry-15 II-class Sunday; on such a Sunday, band now returns one worse than entry 15's own value rather than the literal 8 -- strictly worse, not merely different, since an exact tie would fall to Precedence.resolve's slug tie-break, which for "ef-all-souls" against a Sunday slug would make All Souls win the tie anyway. Entry 8's own rank is untouched, so Task 8's disposition still sees a true I-class candidate to transfer. Entry 14 (Feasts of the Lord, II class) added a universal-layer restriction the register's line 341 does not carry -- contrast entry 16 at line 342, which explicitly says "not of the Lord"; RG 37c (register line 393) also speaks of "II-class feasts of the Lord" with no universal qualifier. Dropped the layer test: a proper or indult feast of the Lord now bands 14, not 19/20. Also exposes vigil_suffix and ember_prefixes from precedence_ef.mli, matching universal_layer/indult_prefix's existing "colitur convention, not an RG citation" treatment -- both were previously private literals duplicated in the test file, so a rename of temporal_ef.ml's slug format could have drifted silently past both sides agreeing with each other. Two test rows now build their candidate from Temporal_ef.temporal's own real output (entry 18's Lent Ember day, entry 21's Ascension Vigil) instead of a hand-typed slug, closing that specific coupling. Adds the three cheap rows review named as closing the remaining unpinned guards (a temporal-origin Class1 candidate on an unnamed date; a universal Class2 vigil of the Lord; a non-universal Class3 vigil), plus a resolve()-level test proving the Sunday is actually observed over All Souls, not just that band returns the right integer in isolation.
* rite(ef): RG 91 Table of PrecedenceLukasz Kasprzak2026-08-111-0/+202
Precedence_ef.band transcribes RG 91's 28-entry Table of Precedence (rules-register.md ยง4) for the EF rite: given a day's context and a candidate celebration, returns the table's own entry number, 1-28 (I class 1-13, II class 14-21, III class 22-26, IV class 27-28); lower wins. Every branch carries its entry number and register citation in a comment, checked in the table's own numeric order. Two entries are transcribed as the register states them even though they invert the pattern the rest of the table follows: at III class, 23 (particular calendars) outranks 24 (universal), the reverse of how 11/12 and 14/16/19/20 rank a universal feast ahead of a proper one at I and II class. Sanctoral-origin, layer-decided entries (11-13, 14/16/19/20, 23/24) follow the brief's structural insight: a celebration whose layer is not the universal base is an overlay -- proper, or indult if its layer id also carries the indult prefix. Neither the universal-layer id nor the indult prefix is an RG citation; both are colitur's own data-modelling convention, exposed from the module so whichever task loads the real EF sanctoral overlays can align to them. Vigils (21, 26) are read off the temporal cycle's own -vigil slug suffix rather than gated on origin, since a II/III-class vigil can be either temporal-origin (Ascension, already produced by temporal_ef) or sanctoral-origin (a saint's vigil, no task has loaded yet); Ember days (part of entry 18) are read off temporal_ef's own ember slug prefixes rather than re-derived, since the September anchor is independently flagged there as one of the more contested dates in the calendar. A candidate shape the table has no row for (e.g. a Class1 vigil that is not Nativity or Pentecost, or a Class4 candidate marked as a vigil -- RG 91 has no IV-class vigil either) returns a dedicated unclassified sentinel (max_int) rather than being folded into a same-rank entry it does not belong to. test_precedence_ef.ml is table-driven: one Alcotest.test_case per RG 91 entry (55 rows total, several entries covered by more than one named day so a single missed offset cannot hide behind a passing sibling), each date computed from Computus.gregorian_easter rather than hand-typed, so an arithmetic slip cannot pass by accident.
