* fix(cli): publish --prune refuses a manifest entry that escapes --outLukasz Kasprzak2026-08-191-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRITICAL: .colitur-manifest lives INSIDE the tree publish writes into -- the very tree this feature exists to have committed into a git repo. A manifest entry with a ".." path component, or an absolute path, let --prune Sys.remove/Unix.rmdir a file OUTSIDE --out. No attacker is required: an ordinary bad merge, a conflict resolved the wrong way, or a hand-edit of that file is enough to plant such an entry, and publish's own stated contract -- it never deletes a file it does not own -- broke outright the moment one was present. Two independent checks, both required, applied before every deletion: - structural (manifest_entry_is_safe): reject an entry that is absolute or has a ".." path COMPONENT, by splitting on '/' and comparing components, not by substring-matching ".." (which would wrongly reject a legitimate name like foo..bar). - containment (resolves_under): resolve both --out and the candidate with Unix.realpath (closing a symlink-inside-out gap the structural check alone would miss) and verify the candidate is a genuine path descendant of --out, not merely a string with the same prefix. Applied at both the file-deletion loop and prune_empty_dirs' own directory removals. A rejected entry is skipped with a one-line stderr warning; publish completes rather than aborting -- a corrupted manifest must not make the tool itself unusable. test/cli.t reproduces the exact canary scenario (a ".." entry surviving deletion of a file outside --out), an absolute-path entry, and a legitimate dotted filename (no .. component) still pruning normally, alongside the existing --prune coverage.
* feat(cli): colitur publish -- the static treeLukasz Kasprzak2026-08-192-1/+449
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writes ef/<year>.{json,csv,xml,ics}, one JSON per day, the schema and a generated index. That tree is the API: any web server or git repo serves it, and nothing runs at request time. Deterministic: publishing twice is byte-identical, asserted in cli.t. That is what makes publishing into a git repo safe -- the diff shows only real change, and you review it before pushing. Non-destructive: a manifest records exactly the files this tool wrote, so --prune can only remove files a previous run created. A file you put in the output directory yourself is never touched, with or without --prune. Asserted in both directions. Pruning a stale file also removes any directory it leaves empty behind it (e.g. an old year's own ef/<year>/ tree), stopping at --out itself -- without this, a pruned year's own directory would survive empty and test -d would still see it. schema/day-v1.json is resolved the same prefix-relative way data/ef's own sexp files are (installed vs build-tree, probed rather than assumed), never from cwd, and a missing schema fails with one line on stderr before anything is written rather than emitting an empty file. Needed schema/day-v1.json wired into the root dune file's default alias and into test/dune's cram deps -- unlike data/ and templates/, nothing made dune mirror schema/ into the build tree before this. unix is added to bin/dune's libraries for mkdir_p; it ships with the compiler, so colitur.opam and dune-project are unchanged.
* feat(templates): wall calendar grid in LaTeX, groff and HTMLLukasz Kasprzak2026-08-195-2/+657
| | | | | | | | | | | | | | | | | | | | | | | | Three flavours, not six: a month grid in Markdown or plain text is a worse artefact than the booklet already is, and shipping a template we would not use ourselves is maintenance with no reader. These are the first templates to use weeks and in_month, so this is where the view model earns its keep -- the booklet and the grid come from one model with no second code path. Every cell carries a per-cell 'last' boolean (already in the view). A table row needs a separator BETWEEN cells and the engine deliberately has no 'unless last' construct; the rule is shape the data, not the template. Without it the LaTeX grid emits eight columns for seven cells and pdflatex rejects the file. Day cells resolve their label as {{#name}}{{la}}{{^la}}{{slug}}{{/la}} {{/name}}, never a bare {{name.la}}: the enclosing month object has its own name.la, and the engine's scope lookup falls back outward, so a bare dotted lookup would render the month's own Latin name on every day lacking one -- a wall calendar where every day reads "January". Verified on the goldens: Ianuarius appears exactly once per file, the month heading, never as a day label.
* fix(cli): guard the whole template read, not only the openLukasz Kasprzak2026-08-191-0/+9
| | | | | | | | | | | | | | | | | | read_file guarded open_in_bin but left in_channel_length and really_input_string unguarded, so a path that opens but cannot be read as bytes -- a directory -- escaped as an uncaught Sys_error and crashed the program, leaking the open channel on every failure path. A template is user input; it must never crash the program. Wrap the whole read in Fun.protect so the channel closes on every path (success, exception, early return), matching the close-on-every-path pattern already used in the test suite. The missing-file message stays exactly as before; a read failure after a successful open now carries the exception text, the same path: exception shape Layer.load and Overlay.load already use. New cram case points --template at a directory (the sandbox's own cwd, not /tmp) and asserts one stderr line and exit 2, not a crash.
* feat(templates): ordo booklet in six flavours, pinned by goldensLukasz Kasprzak2026-08-199-2/+14728
| | | | | | | | | | | | | | LaTeX and groff are the print paths; HTML carries a print stylesheet; AsciiDoc, Markdown and plain text are the plain-consumer paths. AsciiDoc and Markdown use flavour none, and say so in a comment: their metacharacters are context-dependent and escaping them aggressively produces worse output than not escaping. The consequence is real and documented -- a feast name containing * renders as emphasis. Golden tests pin all six byte-for-byte for 2027. They prove the templates RENDER, not that they TYPESET; compiling needs TeX and groff, which is Task 13's opt-in make check-templates.
* feat(cli): colitur table and renderLukasz Kasprzak2026-08-191-0/+69
| | | | | | | | | | | | | | | Computes and renders in one process. There is deliberately no stdin-fed render: honouring the pipe would need a JSON parser we would have to write, purely to serialise and immediately re-parse our own view -- a second hand-rolled component and a second place for the contract to drift, for no benefit. colitur emit --format json | jq still composes. An unknown extension with no --flavour is an error naming the six valid flavours, never a silent fallback to none: guessing wrong produces malformed output that looks fine until it does not. A malformed template reports the parser's own reason and exits 2. A template is user input; it must never crash the program.
* fix(render): omit DTEND at the domain's own last day, 9999-12-31Lukasz Kasprzak2026-08-191-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | F1: Date.add_days is UNBOUNDED (date.mli) -- only Date.make enforces 1583..9999 -- and Date.to_iso8601 pads but never truncates, so 9999-12-31's naive successor formatted as "10000-01-01", and compact turned that into a 9-digit, non-conformant DATE on the last VEVENT of year 9999. Confirmed at the source before fixing, and reproduced against real `colitur emit --format ics --from 9999 --to 9999` output (DTEND;VALUE=DATE:100000101) before touching any code. RFC 5545 section 3.6.1: a VEVENT with a DATE-valued DTSTART and neither DTEND nor DURATION has an implicit one-day duration, so omitting DTEND for that one event is the standard's own correct answer, not a workaround. dtend_of re-derives the successor's year/month/day and re-validates them through Date.make -- the one function that actually enforces the domain -- before trusting the string; None means the caller omits the DTEND line entirely. F2 (minor, same function): documented next_day's own Error branch as dead-but-silent on shipped data (event's iso <> "" guard is the only caller and always parses) -- behaviour unchanged, comment only. Two new tests: the domain's last VEVENT (DTSTART 99991231) has no DTEND line at all; every DTEND anywhere in a 9999 feed is exactly 8 digits (the general form of the bug, catches a regression anywhere else in the domain too). Existing 2027/2028 DTEND-arithmetic assertions untouched and still pass. Mutation-proved: both new tests fail against the pre-fix code (9-digit DTEND value caught verbatim), pass after.
* feat(cli): colitur emit -- csv, json, sexp, xml, icsLukasz Kasprzak2026-08-191-0/+69
| | | | | | | | | | | | | | | Reuses resolved_year_report's existing two-liturgical-year indexing rather than copying it: that walk owns the civil-vs-liturgical span reasoning, and a second copy would drift. It is refactored to return the days, with the printer layered on top, so day and readings behave identically -- which cli.t proves byte-for-byte. CSV emits one header for a whole multi-year run, not one per year. A reversed range is a usage error rather than silently empty output. Asserted in cli.t: two ics runs are byte-identical, because nothing in the path reads a clock.
* feat(render): iCalendar emitter, RFC 5545Lukasz Kasprzak2026-08-192-1/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | Not a template job: folding, escaping, exclusive DTEND and stable UIDs are rules a logic-less template cannot enforce, and each fails silently in a subscriber's client rather than loudly at generation. DTEND is EXCLUSIVE for an all-day event (section 3.6.1). Wrong here shows every event a day short, everywhere. UIDs are YYYYMMDD-<rite>@colitur and stable across regenerations (section 3.8.4.7). Wrong here duplicates the whole year in every subscriber's phone, months later. Every line is CRLF-terminated and folded at 75 octets (section 3.1). No RRULE: a liturgical calendar is not a recurrence rule. Asserted, so nobody optimises it later. DTSTAMP is a parameter, not a clock read. RFC 5545 requires it and the obvious implementation reads the wall clock -- which violates the kernel's determinism rule and would make two feeds from identical data differ byte-for-byte, defeating reproducible builds and any reviewable diff on a published tree. Corrected one test literal against real engine output: DTSTAMP is a per-VEVENT property (section 3.8.7.2), not calendar-level, so the default-value line count is 365 (every event), not 1. Mutation-tested: a non-exclusive DTEND reddens the suite.
* feat(render): XML emitter and schemaLukasz Kasprzak2026-08-192-1/+36
| | | | | | | | | | | | | Element-per-field; attributes carry identity only and there is no mixed content, so a consumer's XPath never has to distinguish the two. Schema validation is an opt-in make check-schema via xmllint, not an in-suite assertion: validating XSD needs an XML library and the dependency list is frozen. It prints SKIPPED loudly when xmllint is absent, because a silent skip reads as a pass. The suite asserts well-formedness properties directly instead. This corrects the design spec, which claimed in-test validation.
* feat(render): CSV and JSON emitters, and the published contractLukasz Kasprzak2026-08-192-1/+79
| | | | | | | | | | | | | | | | | | | | | Both consume the VIEW, not the kernel, so every emitter and every template describe exactly the same fields -- there is one vocabulary, not five. CSV is RFC 4180: a field with a comma is quoted. That is live on real data, not hypothetical -- 'St. Joseph, Spouse of the Bl. Virgin Mary' would otherwise split into two columns. JSON is hand-rolled because the dependency list is frozen and escaping is the only subtlety. Control characters below 0x20 are \u-escaped per RFC 8259 section 7. There are no numbers in the view, deliberately: a consumer never has to guess whether week is 2 or "2". schema/day-v1.json pins the shape. Once a phone subscribes or a site fetches this, it is a promise to strangers -- adding a field is minor, renaming one means /v2/.
* feat(render): the view modelLukasz Kasprzak2026-08-193-1/+186
| | | | | | | | | | | | | | | | | | Shapes a civil year of resolved days into the value a template renders against. This layer is why the engine can stay logic-less: a month grid needs leading blank cells, week bucketing and an in-month test, and a logic-less template can compute none of it. Both weeks and days are offered at every level -- the booklet walks days, the grid walks weeks -- so the two artefacts cannot drift. Colours are six booleans, not hex: hex bakes a presentation policy into the engine, and LaTeX, groff and HTML each want a different colour expression. Asserted: exactly one of the six is true on every day of a whole year, so a template keying off them can never get none or two. Padding cells carry every field a real day carries, empty, so a template never hits a missing key mid-grid.
* feat(render): template renderer with mandatory escapingLukasz Kasprzak2026-08-192-1/+81
| | | | | | | | | | | | | | | | Every interpolated value is escaped for the template's flavour; the template's own literal text never is, because that is the author's markup. There is no raw form, so a template cannot opt out. Scope is a stack with outward fallback, so a grid template can reach the year number from inside a week without the view duplicating it into every cell. A missing key renders empty -- the one deliberate silence, so a template survives a rite that does not set every optional field. Mutation-tested: dropping the Escape.apply call reddens the data-cannot-escape-flavour case.
* fix(render): reject empty tag paths, sharpen the raw-form testLukasz Kasprzak2026-08-191-3/+28
| | | | | | | | | | | | | | | | | | F1: test_no_raw_or_partial_form's first assertion only excluded one literal shape (Ok [Var ["{name"]]), so it could not actually catch a future raw/unescaped constructor under a different name. Replace it with an assertion of the real parse result for {{{name}}} (Ok [Var ["{name"]; Text "}"]), documented behaviour rather than a guarantee this test cannot check -- the real guarantee is structural: node has exactly four constructors and none of them is raw. F2: {{.}}, {{#}}, {{^}} and {{/}} used to parse to a Var/Section/ Inverted with an empty path, reachable but never designed. This engine has no "current context" for a bare dot to mean, so a bare-dot or empty-sigil path is now a parse error at lex time, covering all four sigil forms via one path helper. The existing "empty tag {{}}" branch is unchanged and still reachable (a fully empty body is a distinct case from a sigil with an empty path).
* feat(render): logic-less template parserLukasz Kasprzak2026-08-192-1/+63
| | | | | | | | | | | Placeholders, sections, inverted sections, comments. Nothing else: no partials, no lambdas, no expression evaluation, no raw form. A template is data, never a program, which is what keeps an untrusted template safe. Errors rather than silence on a malformed template: an unterminated tag, an unclosed section, a mismatched close and a partial all return Error. Swallowing '{{name' as text is how a typo becomes invisible missing output in a printed booklet.
* fix(render): make fold_ics total on arbitrary octet stringsLukasz Kasprzak2026-08-191-8/+34
| | | | | | | | | | | | | | | | | | | fold_ics's UTF-8 backoff loop could back `cut` all the way down to `pos` on 74+ consecutive continuation bytes (0x80-0xBF), producing a zero-length chunk and recursing on the identical position forever -- not producible by valid UTF-8, whose longest continuation run is 3, but the kernel's own totality requirement covers arbitrary octet strings, not only valid ones. When backoff finds no boundary inside the window, cut hard at the limit instead, so forward progress is unconditional. test_fold_never_splits_utf8 previously asserted only that unfolding reproduced the original bytes, a property folding preserves at any cut position and therefore blind to a boundary violation. It now also asserts the named property directly: no continuation chunk may start with a UTF-8 continuation byte. A new regression test feeds fold_ics 100 consecutive continuation bytes and asserts it terminates with every line at or under 75 octets.
* feat(render): per-flavour escaping and RFC 5545 line foldingLukasz Kasprzak2026-08-193-2/+96
| | | | | | | | | | | | | | | Six flavours: latex, groff, html, xml, ics, none. Markdown, AsciiDoc and plain text map to none deliberately -- their metacharacters are context-dependent and escaping them aggressively produces worse output than not escaping. An unrecognised extension returns None rather than falling back to none: guessing the flavour wrong produces malformed output that looks fine until it does not. Folding backs off to a non-continuation byte, so a fold never splits a UTF-8 sequence -- the failure mode that would corrupt Polish and Latin names in a published feed.
* test(differential): C14 and C15 closed -- only slug vocabulary remainsLukasz Kasprzak2026-08-183-44/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lectio adopted the last two Missal corrections colitur argued: C14 3 -> 0 RG 96(a)/97/98. lectio resolved each impeded I-class feast's transfer independently, so in 2008, 2035 and 2046 St Joseph and the Annunciation both walked onto the Monday after Low Sunday and Joseph, losing there, was observed on no day of those years at all. It now resolves the year's transfers as a set: the Annunciation takes the Monday as its sedes propria, Joseph the Tuesday. C15 7 -> 0 The Holy Family propers' own 13-January rubric, "sine commemoratione Baptismatis D.N.I.C.". lectio kept the Baptism as the observed office on all seven such years in 2005-2050. Those were the last two BEHAVIOUR classes. What is left is C1 (138) and C6 (119), both pure slug vocabulary. Measured across the whole fixture, applying only the season normalisation the test already applies: 579 of 16801 days differ, and every one of them differs on the SLUG ALONE. Zero days differ on season, rank, colour, Epistle or Gospel. (The test's own norm_slug table already maps 322 of the 579; the 257 left are C1 and C6. The field profile is the same either way.) So the two engines now agree on every liturgically meaningful field on every day of 2005-2050. The residue is what the two projects call things -- ef-christmas-2-friday against ef-time-after-epiphany-1-friday for the same day, same Mass. Aligning it means renaming lectio's slugs, and those are keys: its lectionary, clectio's generated tables and any user overlay are built on them. Left as vocabulary rather than forced. Fixture refreshed against lectio e713da2; 13 rows changed, colitur agrees with all of them. 24 divergence classes at the start of this work, 2 now.
* test(differential): C31 closed -- 4 classes left, 257 of 267 rows are namingLukasz Kasprzak2026-08-183-124/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | The ferias between Epiphany and the first Sunday after it repeat Epiphany's own Mass in lectio now; they had been taking the Mass of the Sunday that follows them. C31 98 -> 0 C1 40 -> 138 grew, and changed character C1 is now SLUG VOCABULARY ONLY, and its note says so. Season, rank, colour and both citations agree with colitur on every day of the January window; what differs is the identifier -- ef-christmas-2-thursday against ef-time-after-epiphany-1-thursday for the same day with the same Mass. C6 is the same shape. That is 257 of the 267 remaining rows. Aligning the vocabularies would mean renaming lectio's slugs, and those are keys: its own lectionary, clectio's generated tables and any user overlay are built on them. Recorded as vocabulary rather than closed, because the rows do differ -- just not in anything a reader of either engine's output sees. Measured for 2026: season, rank and colour agree on all 365 days; 14 days differ and every one differs on the slug alone. 5 classes -> 4, agreement 98.4%.
* test(differential): C20 and C38 closed -- agreement 98.4%Lukasz Kasprzak2026-08-183-276/+223
| | | | | | | | | | | | | | | | lectio carries the readings of the nine Common-routed saints and of three more that had proper Masses but no reading at all. Every day of 2005-2050 now resolves a reading there; four days used to come back empty. C38's own note said it could not close without lectio gaining a Commons concept. The readings arrived instead of the abstraction, which was enough: each Common resolves to one first/gospel pair for the saint that names it, so a table plus assignment layer would have bought indirection and nothing else. C20 14 -> 0 C38 70 -> 0 7 classes -> 5, 351 rows -> 267, agreement 97.9% -> 98.4%.
* test(differential): seven classes closed -- agreement 93.9% to 97.1%Lukasz Kasprzak2026-08-183-961/+910
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lectio gained the Passiontide week split and thirteen lectionary entries. C23 230 -> 0 Holy Week's own six Masses C32 99 -> 0 C35 60 -> 0 the first weeks after Epiphany and Pentecost (RG 299) C33 46 -> 0 Corpus Christi C34 46 -> 0 the Sacred Heart C26 43 -> 0 Passion Tuesday C19 7 -> 0 the Holy Family week-index residue C1 75 -> 40 C31 63 -> 98 GREW The Passiontide split is the one that carried most of this. efWeek had no Passiontide case, so both weeks numbered 0 and every day of Holy Week took the slug of its Passion-week namesake -- one set of readings for two weeks with entirely different Masses. Good Friday was reading Passion Friday's. C31 growing is the same bookkeeping as C1's earlier growth and is recorded in its own note: C32 and C35 closed, and rows that carried several causes now carry only this one. Nothing new disagrees. 17 classes -> 10, 1019 rows -> 488, agreement 93.9% -> 97.1%. What remains is almost entirely NAMING rather than disagreement: C6 (119) is colitur's ef-nativity-octave-day-N against lectio's ef-christmas-N-weekday on days where both now read the same Mass, and C1 (40) is the same shape in the January window.
* test(differential): C8 closed, C6 narrowed to namingLukasz Kasprzak2026-08-183-147/+147
| | | | | | | | | | | | | | | | | | | lectio gained Rogation Monday and Tuesday (RG 87, violet under RG 128(d)) and the Missal's own Mass for the weekdays within the Octave of the Nativity ("Diebus infra octavam Nativitatis Domini", Titus 3:4-7 / Luke 2:15-20). C8 26 -> 0 CLOSED C6 119 -> 119 narrowed: the cause halved, the count did not C6 is worth reading carefully rather than skimming the number. Its rows no longer differ on First_f or Gospel_f at all -- the two engines now read the SAME Mass on 29-31 December, where lectio previously served the Sunday's. What is left is Slug_f alone, colitur's ef-nativity-octave-day-N against lectio's ef-christmas-N-weekday. That is vocabulary, not disagreement. The count did not move because the entry's gate already admitted a Slug_f-only subset, which is exactly the case where a row count is a misleading summary. 17 classes, 1019 rows, agreement 93.9%.
* test(differential): C17 closed -- the largest divergence class is goneLukasz Kasprzak2026-08-183-1149/+1149
| | | | | | | | | | | | | | | | | | | | | | | | | | lectio built the votive Office of Our Lady on Saturday (RG 78) and then said RG 309(a)'s own Mass for it. Both halves were needed: RG 78 keeps the office and gives it white, RG 309(a) picks among the Missal's five seasonal formularies. Fixing only the first leaves the day announcing Our Lady and reading the feria's Mass -- the bug colitur itself shipped briefly and fixed in its v0.3.0. C17 439 -> 0 CLOSED -- the largest class between the two engines C31 103 -> 63 Saturdays that carried both causes; only this one left C35 69 -> 60 same C1 35 -> 75 GREW C1 growing is not a regression and is recorded as such in its own note: the January Saturdays C17 used to absorb now differ only on the slug vocabulary C1 already covers, so they land there instead. Rows moved between entries as the larger cause was removed. Also in this refresh, from the same session: weeks after Epiphany now count from the first Sunday after it rather than from 6 January, which took C19 from 35 to 7 -- what remains there is the Holy Family interaction, a different cause needing RG 17(b) in lectio. 19 classes -> 18, 1493 rows -> 1045, agreement 91.1% -> 93.8%.
* test(differential): refresh the fixture -- three more corrections adoptedLukasz Kasprzak2026-08-183-877/+875
| | | | | | | | | | | | | | | | | | | | | | | | | | | lectio has taken three further corrections colitur argued from the Missal: the twelve RG 124 colours (red is for Apostles, Evangelists and Martyrs, and missalemeum had the rule inverted in both directions), Good Friday's black under RG 128(b) with RG 132, and RG 72's Christmas Time boundary at 13 January inclusive. 864 rows changed. Two classes closed outright and two moved: C18 450 -> 0 the RG 124 colours -- the LARGEST single class in this file C36 46 -> 0 Good Friday's colour C1 159 -> 35 the season boundary stopped differing C23 184 -> 230 Good Friday's rows fold back, the split no longer needed C36 is closed rather than kept at zero because the split it represented has dissolved: it existed only to hold Good Friday apart while its diff set had a third member, and with the colour agreeing the rows are the exact pair C23 has always gated on. Restoring 230 is not a regression, it is the number returning to what it was before the split. Cited classes 24 -> 19, divergent rows 2252 -> 1521, agreement 86.6% -> 90.9%. The percentage is again the least interesting part. C18 alone was 450 days on which the two engines agreed about nothing and now agree because both apply RG 124 the same way round.
* test(differential): refresh the lectio fixture -- the lineage invertedLukasz Kasprzak2026-08-183-237/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every previous refresh of this fixture carried lectio's answers TO colitur, because colitur's data was bootstrapped from lectio. This one carries colitur's answers BACK. lectio has merged eight field corrections colitur argued from the 1962 Missal: ubaldus and didacus promoted from commemoration to III-class feast on the Missal's own calendarium, both August vigils recoloured violet under RG 128, and both Ember Saturdays' readings, which lectio had carrying St Thomas's and St Matthew's Masses respectively. 227 of the 16801 rows changed. Three cited classes went to zero and are CLOSED and REMOVED, citations preserved in the register, the same discipline C2-C5, C7, C9-C13, C21, C22 and C25 already record: C27 40 -> 0 the Advent Ember Saturday's readings C28 40 -> 0 the September Ember Saturday's readings C37 77 -> 0 the two vigil colours C37 is worth noting by name: its own note called the shared lineage "the sharpest demonstration in the project", colitur and lectio and missalemeum all carrying the same two wrong colours. Two of the three now carry the right one. C38 NARROWED rather than closed, and the distinction matters. Its identity half is gone -- lectio ranks both saints class-3 now -- but the same 70 rows still differ on readings, because both saints take their Mass from a Common and lectio has no Commons concept to resolve one. It is gated on diffs = [First_f; Gospel_f] exactly, which is C18's shape. It cannot close without lectio gaining a capability, which is a feature rather than a fix. Net: 24 cited classes to 21, 2252 divergent rows to 2095, agreement 86.6% to 87.5%. The number that matters is not the percentage though -- it is that those 227 days now agree BECAUSE BOTH ENGINES FOLLOW THE MISSAL, where before they agreed because both inherited the same errors from Divinum Officium. That is the failure mode CLAUDE.md's lineage note describes, resolved rather than documented, for the first time in this project.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Poland and the Benedictines, in the flat INI form, installed beside the invented diocesan example. poland.ini -- 17 entries from the Calendarium Perpetuum pro Dioecesium Poloniae (1964), promulgated under Rubricarum instructum and applying to the 1962 Missal. Transcribed from a published Polish EF ordo that names that same calendar, cross-checked against missalemeum's supplement page for the two formularies 1964 added (13 and 15 July). Date, Latin name and class were read from the source for every entry; three classes could not be recovered from the PDF's column layout and are marked INFERRED where they appear, with the reasoning. The header carries an edition warning that is a real trap here: the Proprium Poloniae of 1921 and 1934 is still bound into many missals and carries an outdated arrangement of dioceses and ranks. It is not this calendar, and it is exactly the kind of plausible wrong-edition source that has cost this project time before. benedictine.ini -- two entries, and the comment explaining why is the point of shipping it. Counted across the Norcia ordo: 86 "I cl.", 43 "II cl.", ZERO "III cl." and ZERO "IV cl.", against 103 "Semidup." and ~96 "Dup.". The monastic rite uses the Roman classes at the top and the older Duplex / Semiduplex grades below, exactly where the Roman calendar has III and IV class. colitur's rank vocabulary cannot express those, so most Benedictine propers cannot be written here at all -- a mismatch of vocabularies between related rites, not a gap in the data. Rather than invent a Duplex -> Class3 mapping the source never states, that file ships only what its ordo gives in Roman terms and lists roughly two dozen excluded feasts BY NAME, so the omission is visible instead of silent. Both headers say plainly that they are examples and not authorities: they are transcriptions from published ordines, none of the five test layers can vouch for either, and both should be checked against the reader's own ordo. The cram test asserts only what we control -- that they parse, convert and apply -- and says so. They also demonstrate the precedence engine on real data: the Benedictine Transitus is I class and takes 21 March with the Lenten feria commemorated, and Maurus is II class and takes 15 January with Paul the First Hermit commemorated.
* feat(overlay): a flat INI front end, which verifies its own outputLukasz Kasprzak2026-08-183-1/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A convenience format for calendars that add a few local feasts and drop one or two universal entries. Section names are slugs, a [overlay] section carries the id, and status/subject/layer default so the common case -- an ordinary local saint's feast -- says only what distinguishes it. It is a FRONT DOOR, not a second data model. It parses to exactly the Overlay.t the S-expression form parses to, and everything downstream is the same code on the same values; a test asserts an INI overlay and its hand-written sexp equivalent produce identical Overlay.t values. It is also deliberately less expressive -- Add, Suppress and single-field Edit only -- and refuses Replace, multi-field edits and citation edits BY NAME rather than dropping them silently. Anything it cannot say is a reason to write sexp. Little of this is new machinery: tools/bootstrap_sanctoral.ml has parsed INI and mapped it to celebrations since the sanctoral was bootstrapped from lectio. The dates needed extending, since that mapping handled only MM-DD; the flat forms are easter+N/easter-N and mon/day/nth, with nth negative to count from the end. `colitur convert` is a separate step rather than --overlay sniffing the extension, so the author can read what their INI became. When a date form was mistyped, "what did the engine actually get" is the question, and an invisible transpile cannot answer it. The conversion verifies its own output: the emitted text is parsed back with the same function that loads an overlay and must equal what the INI denoted, or nothing is written. That is the point of the module. A transpiler emitting valid-but-wrong sexp is the failure a convenience format invites, and `colitur check` could never catch it -- the output would parse cleanly and mean something else. That check was WRONG on the first attempt, in exactly the way it exists to prevent. It re-serialised the parsed value instead of parsing the text being returned, so it verified t -> sexp -> t, which is true by construction and proves nothing. Found by mutation: corrupting the renderer to emit a different overlay id sailed through and exited 0. It now parses the returned text, the mutation is caught with exit 2, and two tests fail under it where none did before.
* feat(cli): colitur check and colitur new-overlayLukasz Kasprzak2026-08-181-3/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writing a local calendar had no feedback loop. An overlay is applied, not validated -- that stays true, and the five test layers still cannot vouch for a user's file -- but before this the only way to learn whether yours did what you meant was to generate a year of output and grep for your own slug, and the only way to see that a directive matched nothing was to notice a warning scroll past among 365 lines. `check` loads each overlay, applies it to the real shipped calendar, and reports the directive counts, the slug each one targets, and any directive that found no target. It exits 2 when a file fails to load or a directive matched nothing, so it composes into a Makefile or a pre-commit hook rather than merely being readable. It is applied to the SHIPPED calendar and not to an empty layer on purpose: against an empty one every Suppress would fail trivially and the check would be worthless. It answers three narrow questions -- does the file parse, does every directive find its target, what does the merged result contain. It does not validate a calendar against the rubrics and cannot, and both the help text and the man page say so rather than letting the name imply more than it does. `new-overlay` prints a starter to stdout for redirection, rather than writing a file where it likes. Every value in it is a placeholder that will appear in `day` output if left unedited, so a half-finished overlay is visible rather than silently inert, and it documents the three date shapes and the legal values for each closed field inline. load_ef_layer now returns its diagnostics instead of printing them: day and readings still want them on stderr beside a year of output, while check wants them on stdout, attributed to the overlay that produced them, and counted. Printing at the source made the second impossible. The cram test round-trips new-overlay through check rather than pinning the template line by line -- editing its prose should not fail a test, but a syntax error in it still must.
* feat(overlay): default citations and layer, humanise parse errorsLukasz Kasprzak2026-08-181-1/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user-supplied overlay is the only sexp this engine reads that a human writes by hand, and two of Celebration.t's eight fields carry nothing such an author can meaningfully supply: citations is always empty for a local feast, since citations come from the rite's lectionary and never from calendar data, and layer merely repeats the overlay file's own id. Requiring both made the commonest first mistake -- omitting them -- fail with 'lib/kernel/celebration.ml.t_of_sexp: the following record elements were undefined: citations layer', which names a source file the author will never open and does not say what to write instead. A minimal local feast needed 12 lines, two of them noise. Overlay.load now fills each field only where ABSENT, so an explicitly stated value always wins: an overlay may legitimately name a layer different from its own id, and defaulting must not silently overwrite that. A test pins both directions. Deliberately scoped to overlays. Layer.load, which reads the shipped sanctoral, is untouched and stays strict -- that data is the project's own, every field of it is asserted by tests, and a missing one there is a defect rather than a convenience. Parse failures also stop naming kernel source paths: the five prefixes that actually reach a user are rewritten into the vocabulary of the file being edited, and anything unrecognised passes through verbatim rather than being reworded into something possibly wrong.
* fix(ef): the seasonal commemoration comes first (RG 113 sentence one)Lukasz Kasprzak2026-08-181-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "113. Commemoratio de Tempore fit primo loco. In admittendis et ordinandis aliis commemorationibus, servetur ordo tabellae praecedentiae." Only the second sentence was implemented, adopted on ef-rg16a as the admission and ordering criterion. The first -- the commemoration OF THE SEASON is made in the first place -- was not, so ordering ran through band alone for every commemoration including the seasonal one. Reconciled with RG 110(c), which adds the inseparable Peter/Paul pair "ante omnes alias commemorationes". Both rubrics are primary-source certain: the photographic scans' OCR is illegible at RG 110(c), but docs/research/LT.txt, the electronic transcription, carries the Rubricae Generales complete, and O'Connell's footnote 39 turns out to render that clause exactly rather than gloss it. They share a technical term. RG 113's own sentence fixes the sense of "aliae commemorationes" as the ones other than the de Tempore one it has just placed primo loco, and RG 110(c) sits three paragraphs earlier in the same code. Read consistently, the pair heads the OTHERS, not the whole list: season, then the pair, then the table order. So this runs after rg110_additions, and List.partition's stability keeps the pair adjacent while the seasonal commemoration steps in front of it. Blast radius, two full 1583-9999 sweeps diffed: 3 533 days, every one ORDER-ONLY -- the commemoration set is identical on both sides of every changed day, checked as sorted multisets, zero days where anything else moved. All are 22 February with chair-of-st-peter observed. Exactly the population measured before the rule was written. The order-sensitive test row is in test_precedence_ef.ml's admit_cases, which is still the only place in the suite that asserts commemoration order at all. It needed a mixed-origin candidate: every other candidate in that table is origin = Temporal by default, so the rule is an identity on them.
* fix(ef): ubaldus and didacus are III-class feasts, not commemorationsLukasz Kasprzak2026-08-184-2/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both carried rank Class3 with status Commemoration_only, bootstrapped from lectio, which inherits it from missalemeum, which is generated from Divinum Officium. The Missal's own universal calendarium ranks both "III classis" outright, with no commemoration rubric: "S. Ubaldi Ep. et Conf., III classis" (16 May) and "S. Didaci Conf., III classis" (13 November), corroborated in the second scan and in a published 1962 Ordo. Universal by construction, not by assumption: the calendarium carries no "pro aliquibus locis" marker in its 573 lines while the wider Missal carries 79 of them elsewhere. Each saint also has his own Mass entry in the Proprium, which a bare commemoration never has -- a commemoration carries an oration only. Found by auditing ALL 290 fixed-date entries against that calendarium, day by day, anchored on the Roman calends column because the arabic day column is OCR-wrecked and the dominical-letter column vanishes in some months. These two were the only status defects in the whole file. The 15 days the automated pass could not cover were read by hand and all agree. Neither needed a proper authored: each takes its Mass from a Common with only its own Oratio proper, per its own rubric at its own date. ubaldus shares patrick's Common exactly. didacus needed one newly transcribed -- common-of-a-confessor-not-a-bishop-2, the "Altera Missa" Iustus, 1 Cor 4:9-14 and Luke 12:32-34, read independently in both scans, which agree, so the page-image third reading this file's method requires on disagreement was not triggered. Blast radius, full 1583-9999 sweep, every day classified: 13 036. That is 5 564 ubaldus observed, 7 196 didacus observed, and 276 where the Ascension Vigil still wins on 16 May but its single RG 111(c) slot passes from rogation-wednesday to ubaldus -- correct and already pinned, since the Rogation days are the MINOR Litanies and so an ordinary commemoration, which RG 113's table order ranks below a III-class feast. Cited as C38 (70 rows) and M30 (3); C8, C17 and M18 shrink accordingly, each with the reason recorded rather than the count silently adjusted.
* fix(ef): the Assumption and St Lawrence vigils are violet (RG 128)Lukasz Kasprzak2026-08-183-1/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RG 128, transcribed in the rules register since 2026-08-11, gives violet to "vigils of II and III class outside Paschaltide". The Vigil of the Assumption (14 August, II class) carried White and the Vigil of St Lawrence (9 August, III class) carried Red. Both are outside Paschaltide, so both are violet. The Ascension's vigil is untouched: it is the one II-class vigil inside Paschaltide and was already correctly white. The rule had been sitting in the register, disagreeing with the shipped data, since before the data was bootstrapped. It was invisible because colitur, lectio and missalemeum all carried the same two wrong colours -- colitur was bootstrapped from lectio, lectio's ini is generated from missalemeum, and missalemeum uses Divinum Officium's data files. Three sources agreeing is one source counted three times, and the differential and the oracle both went green on the shared error. It surfaced only against witnesses outside that tree: a published 1962 Ordo flagged the Assumption's, and O'Connell, The Celebration of Mass 4th ed. (1964), section 4(c) and footnote 169, gave the general rule and with it St Lawrence's, which the Ordo omits entirely. Two golden pins added, in years where each vigil is actually observed rather than impeded. The divergence this creates against every DO-lineage source is cited in both allow-lists: C37 (lectio, 77 rows -- 92 possible minus 15 where the vigil falls on a Sunday) and M29 (missalemeum, 3 rows in 2026-2027 and 2 in each of 2035 and 2038). Both gated on the exact slugs or dates and on colour alone, so any other divergence on those days would still surface. Also recorded, no code change: rose on Gaudete and Laetare stays. RG 131 is permissive ("adhiberi possunt") and the Ordo prints violet, so the colour field carries a permission rather than a requirement on those two Sundays a year -- a decided position now, not an unexamined one.
* fix(ef): Good Friday is black, not violet (RG 128(b), RG 132)Lukasz Kasprzak2026-08-182-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | RG 128(b)'s own exception list, transcribed in the rules register and primary-source-verified since Task 16, excepts "Actione liturgica feria VI in Passione et Morte Domini usque ad Communionem exclusive" from the violet that otherwise runs from Septuagesima to the Easter Vigil. RG 132 assigns black there. The register recorded this as an acknowledged gap rather than a disputed reading -- the code comment beside the Holy Thursday exception says so in as many words -- and it is closed here. Found by two witnesses outside the Divinum Officium lineage that colitur, lectio and missalemeum all share: O'Connell, The Celebration of Mass, 4th ed. (1964), revised throughout to the Codex Rubricarum (1960) and the 1962 Missal, and a published 1962 Ordo. Both say black. So does missalemeum's own colour set, which orders the day "bv". The rubric is per-action ("usque ad Communionem exclusive") and the model emits one colour per day; black is the day's principal one, the same acknowledged limit RG 126's Palm Sunday blessing already carries. Blast radius: one day per year, colour only, across the whole 1583-9999 domain. Two golden pins re-pinned. Good Friday's 46 differential rows leave C23 for a new C36 gated on the exact triple [First_f; Gospel_f; Colour_f], so C23's own exact-pair gate still means what its note says for its remaining four days: 184 + 46 = 230, no residue, both counts from the comparator rather than hand-counted.
* fix(ef): days within the Octave of the Nativity, and RG 69 for 29-31 DecLukasz Kasprzak2026-08-182-6/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | M11 was the one entry in the missalemeum allow-list adjudicated against colitur, and it was right to be. The calendarium directs "Com. octavae Nativitatis" under each of 26, 27 and 28 December (LT.txt:5454-5459) and RG 109(c) makes a commemoration of the days within the Octave privileged. colitur emitted none. The cause was a reasoning error stated in Temporal_ef's own comment: "26-28 Dec are Stephen, John and the Innocents, hence sanctoral". Their office is sanctoral -- those II-class feasts win the day -- but they remain days WITHIN the Octave (RG 67, "Dies infra octavam sunt II classis"), and colitur built them as generic Class4 ferias. With no octave-day candidate there was nothing for the feast to be commemorated over. Building days 2-4 exactly as days 5-7 always were makes the commemoration fall out of the existing machinery rather than needing a special case: the feast wins on rank, the octave day loses, RG 109(c) privileges it, RG 111(c)'s single slot goes to it. A second, independent defect surfaced while fixing it. The octave-day branch covered 29-31 December unconditionally, so a Sunday falling there got a feria identity -- where RG 69 says a Sunday occurring 26-31 December SEMPER keeps its own office and commemorates the feast. Confirmed against the oracle rather than argued: missalemeum shows "Sunday in the Octave of Christmas" on 2035-12-30, a Sunday, where colitur showed a feria. Both named and anchors now exclude Sundays; anchors had asserted the octave slugs unconditionally and was wrong the same way. Blast radius, full sweep against the pre-change binary: 25251 days, every one 26-31 December, exactly two shapes, zero unclassified -- 21653 carrying an octave-day slug and 3598 that are all Sundays, the RG 69 correction. Allow-lists: M11 closed and removed. C6 narrowed 138 to 119, nineteen of its days having changed temporal identity rather than verdict. M15 widened 18 to 22 -- both streams now commemorate the octave, but the candidate is temporal-origin and carries no English name to match against missalemeum's own, this entry's documented limit on four more dates. Stated rather than glossed: this trades a substantive divergence, colitur omitting a commemoration the Missal directs, for a comparator limit, the commemoration existing but not being name-matchable. That is a real improvement, but what the oracle now proves is that both streams commemorate something on those days; the identity rests on the rubric and the calendarium. Register: section 6.17.
* test(oracle): compare commemorations in the live windowsLukasz Kasprzak2026-08-181-7/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commemorations were checked against an oracle in the 2026-2027 fixture alone -- 227 days out of roughly 968 000 commemoration-bearing days in the domain, about 0.02%, and by some distance the thinnest axis in the project. Layer 3's 16 801 days compare none of them and never can: lectio's trailing "+slug" tokens are its losing candidates, not an RG 111 admitted set. About a third of all days carry a commemoration and admit is the most intricate code in the engine, so the gap was worth closing. 2035 and 2038 now compare presence, count and identity, reusing the 2026-2027 comparator's own identity_diff with the same limits: a sanctoral-origin commemoration resolves by colitur's English name, a temporal-origin one cannot and is reported as a counted, classified outcome rather than a silent pass. Observed-identity stays out deliberately -- that is M18's separate limit and folding it in would flood these windows with a class that says nothing about commemorations. 36 differing rows across 730 days, every one classified. The great majority of commemoration days agree, which is the headline. Four rows are not calendar differences at all but name forms -- colitur's "The Seven Sorrows of the Blessed Virgin Mary" against the oracle's "For Our Lady of the Seven Sorrows", "The Major Litanies" against "Pro rogationibus" -- which is this month's new entities appearing correctly in windows that had never seen them. One finding is genuinely new. On 2038-06-02 the Ascension Vigil admits one commemoration under RG 111(c) and two candidates compete: rogation-wednesday and sts-marcellinus-peter-erasmus. Both are Commemoration_only, so neither has a row in RG 91's table, band returns unclassified for both, RG 113 has nothing to order by, and admit falls through to its alphabetical slug tie-break -- which decides the day. missalemeum keeps the saints. That tie-break was already documented as existing only between two Commemoration_only candidates; this is its first live, externally-witnessed instance, and the decision is made by slug alphabet, which is arbitrary and not rubrical. There may be a real rule going unused: RG 113's first sentence is "Commemoratio de Tempore fit primo loco", and a Rogation is arguably de Tempore -- which turns on whether the entry should carry subject Temporal rather than the Saint it inherited from the Major Litanies precedent, a question the movable-date-specs spec deferred as behaviourally inert and which demonstrably is not. Not decided here. Adopting whichever answer matches the oracle is exactly the reasoning this project refuses, so it is recorded and cited for a task that can weigh it on its own terms.

* feat(data): ship a worked example overlay calendarLukasz Kasprzak2026-08-183-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `--overlay` shipped last week with nothing to point at. The only example was a test fixture, explicitly labelled invented and living where no user would find it, so "colitur supports local calendars" was true but undemonstrated. data/ef/examples/diocesan-example.sexp is installed to <prefix>/share/colitur/examples/ and is runnable documentation: every celebration in it is invented, with example- slugs that cannot collide, and its header explains the four directives, the three date shapes, and the field vocabularies before showing any of them. It demonstrates the range deliberately rather than the minimum: a fixed-date local patron with its own propers; a movable dedication on the first Sunday of October, I class because a church's own dedication anniversary is I class in that church and at III it would lose to the Sunday every year; an Easter-relative commemoration; an Edit raising a universal feast for local use; and a Suppress shown commented out, because suppressing a universal feast is a real liturgical act and an example should not invite it casually. Two things the header says plainly, since this is the one file that lets someone change what colitur computes: an overlay is applied ON TOP of the shipped calendar and never instead of it, and an overlay is applied, NOT validated -- the five test layers assert things about the shipped data and cannot vouch for a user's file. A test asserts it loads against the real EF rank vocabulary, still demonstrates at least four directives, and applies with NO diagnostics. The last matters most: a directive naming a slug the universal calendar lacks would warn, and an example that warns teaches the wrong lesson. It deliberately does not pin which days it produces -- those celebrations are invented, and pinning their dates would make an illustrative file behave like calendar data.
* test(oracle): a third window, 2035, witnessing common-of-doctorsLukasz Kasprzak2026-08-175-5/+541
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Step 4's blind spot is now closed as far as the method allows. 2038 witnessed two of the five Common-routed saints; isidore-of-seville is the third and the last that any year in 2005-2050 can reach, being observed only in 2008, 2035 and 2046. He is also the only saint routing through common-of-doctors, so that Common had never been compared against any external source in any window. Three independent agreements on it: the scan (Commune Doctorum, scan1:41878ff, 2 Tim. 4, 1-8 / Mt. 5, 13-19), colitur, and missalemeum's own 2035-04-04 row. Asserted by date in its own test rather than folded into an aggregate count, so a regression there cannot hide. The remaining two saints are unreachable by construction, not for want of a fixture: gregory-the-great and patrick both sit in March and are impeded by Lent's privileged ferias in every one of the 46 years the differential covers. The blind spot is closed to its limit, not closed absolutely, and the register says so. The comparator is generalised rather than copied -- compare_live takes a fixture and a year -- so a fourth window would cost a fixture and a count list. 2035 differs on 3 days, both families pre-existing and already cited. 2035-04-02/03 are the Joseph/Annunciation transfer pair landing in the opposite order from missalemeum's: neither stream loses a feast, the sequence differs, which is C14's own RG 96 collision finally getting an oracle window. 2035-12-30 is the Sunday within the Christmas Octave against colitur's numbered octave-day slug, C6's family. Both are recognised by slug rather than by date, so a year exhibiting only half the shape would surface as unexplained rather than be quietly absorbed. 393 tests green with the exhaustive sweep.

| | | | | | | | | 3 January 2026 is an unoccupied IV-class Saturday, so its office is Our Lady's and now its Mass is too -- the second of the Missal's five, assigned to Christmas through the Purification. The pin held the Christmastide feria's readings, which is what colitur said before RG 309(a) was implemented. Caught by make check on the 0.3.0 release, which is what that gate is for.
* feat(ef): the votive Mass of Our Lady on Saturday (RG 309(a))Lukasz Kasprzak2026-08-173-10/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Register: section 6.13.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not the II-class feast of 15 September, which colitur has had since the bootstrap, but the other Seven Sorrows: the movable commemoration of Passion Friday, of which colitur had no trace at all. The 1962 calendarium lists it at the foot of March, below the fixed dates, exactly where a movable entry belongs (LT.txt:5056): "Feria VI post dominicam I Passionis: Commemoratio septem Dolorum B. Mariae Virg." Note the word -- Commemoratio. Under the 1960 rubrics it is a commemoration, not a feast, so it can never win the day. Friday after Passion Sunday I is Easter-9, confirmed independently by both dates the oracle allow-list already disputed: Easter 2026 is 5 April and M16's date is 27 March; Easter 2027 is 28 March and M13's is 19 March. It could not be built before Date_spec grew Easter_offset -- the same wall Rogation Wednesday hit, and the second entity that work has now unblocked. M16 is re-adjudicated and its verdict REVERSED, from missalemeum to colitur. The entry existed because colitur admitted St John Damascene where missalemeum showed the Seven Sorrows, colitur having no candidate to admit. Both streams now name the Seven Sorrows and that mismatch is gone. What remains runs the other way, and the rubric is explicit: RG 111(d) admits TWO commemorations on a III-class day, RG 113 puts the seasonal one first, and RG 114 omits only what exceeds the number. 27 March 2026 is a III-class privileged Passiontide feria; colitur admits exactly two, the Seven Sorrows and John Damascene, a real III-class universal feast genuinely falling that day. missalemeum admits one and reports John Damascene as displaced, dropping a commemoration the rubric allows. That makes four divergences adjudicated colitur where missalemeum drops or mis-assigns something -- Monica's Epistle, Perpetua's Common, Christ the King's week, and this. Recorded as a pattern rather than four coincidences: the oracle stays a comparison instrument, but its error rate on adjudicated cases is no longer negligible. M13 is untouched and stays open: 19 March 2027 is a different dispute, whether Joseph is displaced from Passion Friday at all, and on a I-class day RG 111(a) admits one privileged commemoration which the feria takes. Blast radius, full 1583-9999 sweep against the pre-change binary: 7874 days, every one carrying the new commemoration, zero unclassified, line counts equal both sides. Register: section 6.12.
* fix(lectionary): the week after Trinity says its own assigned MassLukasz Kasprzak2026-08-172-1/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RG 299 located (scan1:1096-1098), which does two things at once. First it closes a standing gap: the ferial-Mass selection rule was recorded in the register as unconfirmed against the primary source, and step 3 said so in its own comment -- "lectio's own observed behaviour, not a confirmed Missal citation". It is confirmed now. "In reliquis feriis dicitur Missa dominicae praecedentis, nisi a rubricis aliter provisum sit", restated in the propers as "...nisi propria Missa assignetur". Second, that escape clause splits M26 shape 2 in half, which is why the shape was never resolvable as one thing. Shape 2(a), the week after Trinity, is fixed. Trinity is the temporal identity of its own Sunday, so a plain walkback lands on Trinity's Mass -- but the Missal prints a named formula for the following week, "Missa dominicae I post Pentecosten" (scan1:21758), precisely because the feast has taken that Sunday's own. Those ferias now resolve at step 2 from it and never reach the walkback. Shape 2(b), Christ the King's week, turns out not to be a bug at all. No proper Mass is assigned there -- checked directly, no rubric precedes that Mass heading (scan1:39163ff) -- so RG 299's default governs and "the Mass of the preceding Sunday" genuinely is Christ the King's own, which is what colitur emits and missalemeum does not. Kept open only because no rubric specific to that week was located either way; the verdict is now argued from the primary text rather than resting on oracle disagreement. No Thursday in the slug list: Corpus Christi is Easter+60, which IS that week's Thursday every year, so the ferial slug never exists. Found by the bootstrap's own reachability guard refusing to emit a key no Temporal_ef slug can match, not reasoned out in advance. Allow-lists: C35 opened (69 rows, verdict colitur -- lectio still walks back); C17 narrowed 406 to 397, nine Saturdays moving to C35 because they carry both a citation and a colour difference, with C35 gated to require the citation so a colour-only Saturday still falls to C17; M26 narrowed 30 to 27; M18 widened 352 to 355, the same three days keeping only their observed-identity difference.

* test(cli): pin the version's shape, not its literalv0.2.0Lukasz Kasprzak2026-08-171-4/+9
| | | | | | | | | | | The release target bumps bin/main.ml and dune-project, but cli.t pinned the literal too, so cutting 0.2.0 failed `make check` on a cram diff that was purely the bump working correctly. Every release would have had to edit a test for no gain. The shape is asserted here instead. The value is already checked where it can actually drift: the release target requires the freshly built binary to report the version it just wrote.
* feat(cli): --overlay FILE, so a local calendar can be suppliedLukasz Kasprzak2026-08-173-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Overlay algebra has been built and tested since Plan 2, and Date_spec grew movable variants last commit, but there was still no way to hand colitur a file: bin/main.ml applied exactly one overlay, the shipped data/ef/adjustments.sexp, with the path hardcoded. This is the plumbing. --overlay is repeatable and ordered, and applies ON TOP of the shipped adjustments rather than instead of them. That ordering is the whole point: adjustments.sexp carries RG 110's own 30 June companion, the Major Litanies, St Barbara and Rogation Wednesday, and a user file that replaced it would silently drop all four while appearing merely to add a local feast. Overlay.merge is last-writer-wins, so a local calendar can still override a universal entry deliberately, by naming its slug. The dispatch needed real argument parsing. It matched Sys.argv as an exact array, which does not survive a repeatable flag -- two --overlay arguments are a different array shape from one, and each further flag would multiply the patterns again. Flags are now stripped first and the remaining words matched as command plus year. Hand-rolled, because the dependency list is frozen and this is fifteen lines. One defect found by the cram suite on the first run: the unknown-option guard rejected --help and --version, having excluded only their short forms. Refused, not ignored, on easter and temporal. Neither reads sanctoral data -- temporal deliberately runs the cycle before any layer exists -- so accepting the flag there and silently doing nothing is the failure mode this project refuses everywhere else. A file that fails to load is fatal, exactly as the shipped overlay is; a directive naming a slug that does not exist warns on stderr and the run continues. The second matters more for a user file than for ours: a typo in a diocesan calendar should say so rather than quietly do nothing. test/fixtures/overlay-example-diocesan.sexp is a worked example and is labelled as invented, not calendar data. It carries both shapes a real local calendar needs: a fixed-date patron, and a dedication on "the first Sunday of October" -- which is the case the Date_spec work existed to unlock and which lands on 4 October in 2026, 3 October in 2027, 1 October in 2028. The dedication is I class because a church's own dedication anniversary is I class in that church; at III class it lost to the II-class Sunday every year, which a first draft demonstrated correctly and uselessly. The man page gains an OVERLAYS section saying plainly that an overlay is applied, NOT validated: the five test layers assert things about the shipped calendar and none of them can vouch for a file the user supplies. This is the first feature that lets someone change what colitur computes, and that distinction should not have to be inferred.
* feat(kernel): movable Date_spec variants, and Rogation WednesdayLukasz Kasprzak2026-08-177-12/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Register: section 6.10.
* feat(cli): --version, a CHANGELOG, and a release targetLukasz Kasprzak2026-08-171-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | Groundwork for tagging. The project had no version anywhere: not in dune-project, not in the binary, no CHANGELOG, no tags. The version lives in two places -- dune-project, which generates colitur.opam, and a constant in bin/main.ml, which is what --version prints. Two rather than one because dune's watermarking only substitutes in a release tarball, so a binary built the ordinary way from a checkout would report a placeholder. The release target rewrites both and then re-checks both, and finally requires the freshly built binary to report the version it just wrote: a release that bumped one and not the other would ship a binary disagreeing with its own package metadata. --version is deliberately not embedded in the help text. cli.t pins help's first line, and a version there would mean editing a test expectation every release for no gain. The release target mirrors lectio's, refusals included: no release from a dirty tree, none without a CHANGELOG entry for that version, none whose version bump silently failed to apply, and `make check` -- the full 1583-9999 sweep, not the sampling suite -- must pass before the tag is created.
* feat(cli): a Makefile, a man page, and --helpLukasz Kasprzak2026-08-171-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three things the project had no answer for: how to install it without knowing dune, where to read about it, and what it does when asked. Makefile, same shape as lectio's -- PREFIX ?= $(HOME)/.local, BINDIR, MANDIR, and the '## '-comment help target -- so the two siblings are driven the same way. Every recipe wraps dune in `opam exec --`, which is the actual point of having one here: `make build` works from a plain shell with no `eval $(opam env)` first. install goes through `dune install` rather than a hand-rolled copy, because the binary finds its calendar data relative to its own path; the man page is installed separately to share/man/man1, matching lectio. install and uninstall were both run against a scratch prefix and checked: uninstall leaves zero files behind. PREFIX defaults to ~/.local because that is where lectio installs and where it actually lives on this machine, so colitur lands on an existing PATH with no shell change. An earlier install this session went to ~/opt/colitur, which was me over-applying a rule meant for third-party tools to one of the author's own projects; it has been removed rather than left as a second, staler binary competing on PATH. man/colitur.1 documents the four commands, both output formats and why they differ, COLITUR_DATA_DIR and its refusal to fall back, the data resolution order, exit statuses, and -- deliberately -- the limitations: EF only, Epistle and Gospel only with the chants unbuilt and rejected rather than guessed, and the BVM Saturday Mass-selection gap. A man page that only lists what works is half a man page. Renders clean under `groff -ww -z`, no warnings. --help prints to stdout and exits 0; a usage error prints one line to stderr and exits 2. That is the Unix convention rather than a preference: asking for help succeeded and should be pipeable, being invoked wrongly did not and must not pollute stdout. Both directions are asserted in cli.t, along with a loop confirming every command the help text advertises is one the dispatch actually accepts -- the check that catches help drifting away from the code.
* test(oracle): a second oracle year, 2038, closing step 4's blind spotLukasz Kasprzak2026-08-175-7/+667
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Register section 6.7 recorded that step 4 of the reading chain -- the Common route -- had no external witness of any kind, and proved it by mutation: corrupting a Common citation left both the 16801-day differential and the 730-day oracle green. This closes that. 2038 is the only year in 2005-2050 in which two of the five Common-routed saints are the observed office (Perpetua and Felicitas on 6 March, Frances of Rome on 9 March). 365 days were captured live, one request per day, zero failures. A separate fixture, not more rows on the existing one. sources.md already records that the live endpoint has drifted from lectio's archived 2026-2027 snapshot; merging two versions of one source behind a single set of expectations would make any future disagreement unattributable -- calendar or drift, no way to tell. Nothing in the 2038 comparison is checked against the older fixture, and its provenance file says so, along with the fact that a live capture is not reproducible byte-for-byte on demand the way a snapshot-derived one is. 338 of 365 days match. 27 differ, every one of them in a named, already-adjudicated class, none unexplained: 13 the BVM Saturday votive Mass (M26 shape 1), 7 colour (M21), 2 Judith (M28), 2 Christ the King's week (M26 shape 2b), 1 Christmas multi-Mass (M27), 1 Perpetua's Common, 1 new. Each was decided in a different year, so 2038 re-confirms them independently -- the point of a second window is not new rulings but evidence the old ones are not artefacts of their own year. Two findings came out of it. Perpetua and Felicitas: missalemeum serves the Common of Virgins and calls them "Virgins and Martyrs" in its own oration, where the Missal directs "Missa Me exspectaverunt, de Communi non Virginum I loco" (scan1:27634-27635). Both Commons share the Introit Ps 118:95-96, which is exactly why the calendarium qualifies its direction, and both women were mothers. Verdict colitur; the mechanism is located on missalemeum's side, not merely asserted. Passion Tuesday: the Missal prints "Dan. 14, 27 et 28-42" (scan1:11106) and colitur reproduces that two-part form where missalemeum collapses it to 27-42. Same verses; the convention is deliberate, appearing also in the Seven Sorrows and the Common of Non-Virgins. Verdict colitur, cosmetic. Citations are notation-normalised before comparing, as layer 3 already does: Ecclus/Sir, Joann/John, Luc/Luke, Matth/Matt. Each pair was added because a real row needed it, and no target contains its own source as a substring, so the set is idempotent. Not compared, stated rather than left to be found: commemorations and observed-identity. That machinery is built around a date-literal 28-entry allow-list specific to 2026-2027, and re-deriving it for a second year is its own task. 2038 compares rank, colour, Epistle, Gospel. The extractor's day count was hardcoded to 730, which silently forbade any other window. It is now a parameter defaulting to 730, so the existing documented command keeps its guard and a partial fetch still fails loudly instead of producing a short fixture that passes a comparison it never ran. Teeth, by re-running section 6.7's own experiment: corrupting the Common of Non-Virgins II now reddens four tests, two of them external-oracle, where the same mutation previously reddened neither oracle layer. Residual: isidore-of-seville is still unwitnessed and needs 2035 or 2046; gregory-the-great and patrick are never the observed office in any year 2005-2050, so no fixture in that range can reach them. Register section 6.8 and 6.9.
* feat(cli): install the runtime data, and resolve it in three waysLukasz Kasprzak2026-08-171-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `dune install` produced a colitur that could not run: the binary locates its data relative to its own path, nothing installed the four .sexp files anywhere, and an installed colitur exited 2 unable to read sanctoral.sexp. `dune build @install` produced an empty tree. data/dune installs the four RUNTIME files into <prefix>/share/colitur/ef. Deliberately not the two allow-lists: those describe where colitur and a comparison oracle disagree, are read only by the differential and oracle tests, and are meaningless to a running colitur -- installing them would ship an assertion about lectio's and missalemeum's behaviour as though it were calendar data. No glob, on purpose: a glob would silently start shipping them again the moment one was renamed. Resolution now probes rather than computing one path and hoping. An installed prefix is tried first, the build tree second, and a candidate counts only if sanctoral.sexp is actually readable inside it -- so a failed or half-removed install falls through to a working tree instead of shadowing it and failing later with a per-file error. COLITUR_DATA_DIR overrides both and NEVER falls through. This was the one real design question and the first version got it wrong: it treated the override as just another candidate, and a deliberately bogus value produced a full, plausible, entirely un-flagged year computed off the build tree. Someone who names a directory has stated an intent, and silently calendaring off a different one is the silent substitution this project refuses everywhere else. It is now exit 2 naming the directory. Verified end to end, not inferred: installed to a scratch prefix, then ran the binary from an unrelated cwd with no build tree near it, and confirmed 2038-03-06 still resolves Perpetua and Felicitas through the Common route. All four paths exercised -- build tree, valid override, bogus override, and an empty share/ falling through. Environment reads stay confined to bin/. The kernel's contract forbids them and nothing below the CLI learns where the data came from; the loaders take a path.
* feat(cli): colitur readings, one line per dayLukasz Kasprzak2026-08-171-1/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lectionary has been resolvable since Task 4 but invisible from the command line: `colitur day` prints no citations, so the branch's whole deliverable could only be seen through the test suite. A separate command rather than extra columns on `day`, which is where the plan pointed. Its instruction was to append the Epistle and Gospel to each row "matching the existing column style", and that turns out not to be possible: a citation contains spaces and commas ("Ezech 34:11-16", "Ecclus 51:1-8, 12") while a day row is space-separated with a variable-length +slug commemoration tail, so appending them leaves the row unsplittable -- no awk or cut field number recovers where the Epistle ends. That is the opposite of what the row is shaped for. So `day` keeps its format byte-identical, asserted directly in cli.t rather than left implicit, and the citations get their own row with " | "-delimited fields, safe for values containing spaces. Both formats are a stopgap and say so in the source: the design calls for one schema rendered through a logic-less template engine, and two ad-hoc formats are easier to retire later than one overloaded format whose parsing rules nobody wrote down. The year walk is now shared. day_report and readings_report differ only in how a day is printed, and the two-liturgical-year indexing -- with its own reasoning about civil-versus-liturgical spans -- is exactly the part that must not be duplicated and drift. "-" for an absent part, though no EF day can currently print one: layer 2 asserts exactly one First and one Gospel on every day of every year 1583-9999. The CLI still does not assume a guarantee the kernel makes about data rather than about types. cli.t gains the four chain-step cases test_golden.ml pins against the scans, so the CLI path is checked to agree with the library path, plus the 2 January line, which reads the Circumcision's Mass under the Missal's own ferial rubric (scan1:6523-6526) and not RG 17(a). Verified the cram tests actually run and have teeth: corrupting one expectation produces a diff and exits 1. CLAUDE.md: state, test count (369, 370 with the sweep), the readings command and why it is separate, and What's next -- the lectionary landed early rather than inside Plan 4, so what remains there is OF's own lectionary, not the mechanism. Chants stay deliberately unbuilt, and Validate now rejects any part outside First/Gospel.
* test: lectionary properties, golden pins, and the blast radiusLukasz Kasprzak2026-08-172-6/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
