* temporal(ef): Holy Name of Jesus, RG 17(a) -- fallback + Lord subjectLukasz Kasprzak2026-08-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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").
* data(ef): fix round 1 (F6) -- restore C1's provenance record for 361Lukasz Kasprzak2026-08-131-1/+1
| | | | | | | | | | | The previous refresh's own note recorded HOW 368 was derived (a Python cross-check against the comparator's own failure output, not hand-counted and not copied from a green run); this task's rewrite explained WHY 361 replaces it (C15's own split) but dropped the provenance sentence, stating 368 -> 361 with no record of how the new number was checked. Restored: 361 read directly from the OCaml comparator's own failure output, with the 368-minus-7 arithmetic noted as corroboration, not the derivation.
* test(differential): split the Holy Family/Baptism collision out of C1 (C15)Lukasz Kasprzak2026-08-131-2/+7
| | | | | | | | | | | | | | | | | | | | | | | Before this task's Holy Family fix, colitur's generic Sunday fallback lost outright to the fixed Commemoration of the Baptism of the Lord on 13 January whenever it fell on a Sunday, producing the SAME slug lectio's own tridentine-calendar.ini shows there -- squarely inside C1's own 6-13 January blanket (only Season differed). Now that Holy Family (RG 17(b)) correctly outranks the fixed Baptism and excludes it as a commemoration (RG 91 entry 14, RG 112(a)), colitur's own slug on those seven dates (2008, 2013, 2019, 2030, 2036, 2041, 2047) changes to ef-time-after-epiphany-sunday-1 -- a genuine identity divergence against lectio, which has no Holy Family at all. C1's own predicate does not absorb it (jan_6_13_slug has no entry for that slug), so it surfaced as unexplained, exactly the check the task brief asked for: split it out into its own cited entry rather than widening C1's predicate to swallow it silently. C1's own expected_rows moves 368 -> 361 (back to its pre-rebootstrap value, for a third and different reason than either of the first two moves recorded in its own note); the new C15 covers the 7 rows, gated on the literal date list AND colitur's own slug, the same identity guard C1/C6/C8/C14 already apply.
* test(differential): refresh the lectio fixture, close 9 entries, add C14Lukasz Kasprzak2026-08-121-53/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lectio moved 2386a45 -> 3b32c00 (seven EF calendar defects fixed, plus a sanctoral-generator root-cause fix); the committed fixture predates all of them. Regenerated with the same command the provenance note already named (`go run ./cmd/lectio-ef-dump 2005 2050`), read-only against lectio -- nothing there was touched. New SHA-256 asserted in both the provenance note and test_differential.ml's fixture_sha256. The dumper's two new name_en/name_pl columns are kept verbatim (the fixture is meant to be the exact command's raw output; the comparator already discards everything past field 7). Every C-entry's expected_rows was re-derived independently against the refreshed fixture (a Python re-implementation of diff_fields/ layer_c_reason, cross-checked against the real OCaml comparator's own failure output), not transcribed from a green run. Nine entries -- C2, C3, C4, C5, C7, C10, C11, C12, C13 -- now match zero rows and are closed: sexp row removed, layer_c_reason predicate and its now-dead helper bindings removed, citation preserved in docs/research/rules-register.md's new §3d with the specific lectio commit that fixed each one. C1 (361 -> 368) absorbs C13's former 7 rows now that lectio's own slug matches there too. C6 (138, unchanged count) narrows to a slug-only shape now that lectio's rank agrees. C8 (31, unchanged) survives untouched -- lectio still computes no Rogation days. C9's old shape ("Joseph observed ON a Lent Sunday") is also closed, but a narrower, different divergence survived under the same saint's slug: 3 years (2008, 2035, 2046) where Joseph's own congested RG96 walk collides with the Annunciation's separately-transferred "sedes propria". The old predicate's broad "any diff involving this slug" match was silently absorbing both under one citation -- split into a new id, C14, rather than folded back into C9, since the two are unrelated rules. lectio's own commit history (09a1444) documents this residual as a gap it deliberately left unresolved; colitur gives Joseph a real transferred day either way, which is why C14's verdict stands regardless of a genuinely open sub-question (recorded in the register, not resolved here) about which of the two feasts should claim the contested day first under RG98's "prius impeditum" wording. Re-triaged the full remaining 4975 raw differences: only 10 distinct field-diff signatures now, all resolving to Layer A/B noise or the four surviving citations, 0 unexplained. The crude "Sunday-rank" and "Holy Thursday" residues the task flagged both fully resolve once the real Layer A/B machinery runs (season-spelling and week-numbering artifacts, not substantive divergences) -- see the task report for the derivation. Teeth proof: perturbing ferial_rank to reproduce C4's old defect made 140 rows reappear as unexplained (the exact prior C4 count), reverted after capturing the failure message. 277 tests green (dune test) and 278 with COLITUR_EXHAUSTIVE_SWEEP=1 (the extra case is the 1583-9999 sweep itself).
* test(differential): fix round 1 (F2, F5) -- split 13-Jan-Sunday into C13Lukasz Kasprzak2026-08-121-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 13 January retagged subject=Lord (previous commit's regeneration) makes RG16(a) fire on the 7 years it falls on a Sunday within 2005-2050 (2008, 2013, 2019, 2030, 2036, 2041, 2047): colitur now observes the Baptism of the Lord itself where it used to observe the generic Sunday slug. The diff signature against lectio's fixture widens from {season;colour} to {season;slug;colour} -- but jan_6_13_slug already pre-authorised this exact slug across the whole 6-13 January window (correctly, for the other 39 non-Sunday years), so layer_c_reason routed the new, wider-shape rows into C1 unchanged, and C1's own expected_rows (a pure row count) did not move. A count proving cardinality where identity was required -- on the one day this branch itself already flags as still wrong under RG 112. Split into its own entry, C13, matched by an exact 7-date literal list checked before C1 in the if/elif chain. C1's own expected_rows corrected 368 -> 361 (independently re-derived: a Python script reading data/ef/sanctoral.sexp's regenerated output and the committed lectio fixture directly, replicating diff_fields/layer_c_reason's own logic outside the OCaml comparator -- not transcribed from the failing comparator's own count). C13's own citation records a refinement over the coordinator's framing, checked directly rather than assumed: lectio's committed fixture is a frozen snapshot that predates lectio's own equivalent fix to this entry's class field (the same staleness shape as C12). Confirmed by building lectio's own cmd/lectio-ef-dump from its current source tree (read-only) and running it fresh for all 7 dates -- lectio's LIVE engine now agrees with colitur's slug/rank/colour exactly, disagreeing only on season (the already-understood C1 divergence). This is not evidence colitur's answer is right against the Missal -- it is not (register's own RG112 item) -- only that this specific divergence from the fixture is a staleness artifact, not a live disagreement between the two engines' current logic. Also fixes F5: C12's own note said "5 of the 15 corrected slugs" while listing and counting 7 -- corrected to 7. Also corrects the module header's stale "13 January ... slug/rank/colour already equal lectio's exactly, in all 46 years" claim (true only for the 39 non-Sunday years now).
* test(differential): allow-list C12 for the 15-entry rank correctionLukasz Kasprzak2026-08-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Re-bootstrapping sanctoral.sexp (previous commit) makes 7 of the 15 newly-corrected III-class feasts win an occurrence they previously lost as Commemoration_only: RG 91 entry 24 (a universal III-class feast) outranks entry 28 (a IV-class feria), and the occurrence code that resolves this already existed and needed no change. lectio's own committed differential fixture (test/fixtures/lectio-ef-2005-2050.txt) is a frozen snapshot predating lectio's own equivalent generator fix, so it still shows the class-4 feria observed with the same saint only as a trailing commemoration -- a new, expected divergence from that fixture, 14 rows in the 2005-2050 window. expected_rows (14) is independently re-derived by grepping the regenerated sanctoral.sexp's own post-regeneration civil-day output against the committed lectio fixture directly (two flat-file extractions cross-checked against each other), not transcribed from the comparator's own failing-test output. C12 reuses an id last used, and removed, by the RG16(a) task's own reverted Purification retag -- noted at both the old and new entries' own comments so the id's history is visible to a future reader.
* docs(citations): migrate register line-number pointers to stable anchorsLukasz Kasprzak2026-08-121-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* kernel(temporal): Holy Thursday is white, per RG128(b)'s named exceptionLukasz Kasprzak2026-08-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* test: differential vs lectio 2005-2050 with a cited allow-listLukasz Kasprzak2026-08-121-0/+69
Validation layer 3 (design spec's five): compares colitur's real day-by-day EF output against lectio (sibling project, Go), 2005-2050, one line per civil day. Of 16801 day-pairs, 11206 already agree on the seven leading columns; the 5595 that don't resolve into exactly 25 distinct field-diff signatures, all triaged. Three strictly separate layers, per the controller's ruling (the brief's single flat allow-list assumed a handful of differences, not 5595): - Layer A (test_differential.ml, norm_season/norm_slug): vocabulary. An explicit, closed table of naming synonyms with no liturgical substance (lectio's easter/christmas vs colitur's paschaltide/christmastide; a handful of slugs that are two names for the identical office). No wildcards -- every entry is a literal string pair. - Layer B (strip_epiphany_index): numbering. The one slug family whose lectio/colitur index offset is not a constant (Time-after-Epiphany week numbering, register 3c#5) has its embedded digit stripped to a common form on both sides before comparing; rank and colour stay fully compared. - Layer C (data/ef/expected-divergences.sexp): the cited allow-list. Ten genuine liturgical disagreements, each citing its RG paragraph and naming which engine is right (always colitur, verified against the Missal/register, never against lectio's own behaviour). This is the only layer permitted to cover a difference in rank, colour, or which celebration is observed. Five extend or restate register 3c's already- documented divergences (season boundary, Sunday I-class, Advent Ember ferias, Rogations); five are new, found and adjudicated in this task (Lent Ember days, the Nativity Octave, Ember-day-vs-saint precedence, the St Joseph transfer off a Lent Sunday, and the 2011 Sacred Heart / Precious Blood / Visitation collision). expected_rows on each entry is an exact regression pin, asserted by the test, not documentation. 13 January (register 6's long-open "Baptism of the Lord" item) is confirmed empirically fixed already -- Task 11's sanctoral wiring closed it before this task started -- so it is not allow-listed; the only residual difference there is the season boundary already covered by C1. Two stated limits carried from the brief (commemorations are not comparable; lectio's own EF oracle asserts season only, 2025-2026 only, so a rank/colour difference is not presumptive evidence against colitur) plus a third found during this task (the week column is a display convention on both sides, not a liturgical fact, and is not compared at all) are documented in the test file's own doc comment. Fixture: test/fixtures/lectio-ef-2005-2050.txt, committed as plain text (1.4 MB), generated by lectio commit 2386a45; provenance recorded in the sibling .provenance file. Colitur's side is recomputed fresh from the library on every run, through the same Calendar/Rite_ef pipeline `colitur day` uses, not the compiled binary. Proved the harness has teeth by two reverted perturbations: a genuine colour difference injected into a fully-covered fixture row fails the "no unexplained differences" check with the exact mismatched row printed; a one-row drift in an allow-list entry's expected_rows fails the count check independently, showing it is not merely a duplicate of the first assertion. 236/236 tests green, clean-build verified, deterministic across OCAMLRUNPARAM=R.
