deterministic OCaml engine to compute and validate liturgical calendars for multiple rites, template-driven output to year 9999 https://git.labunix.xyz/colitur.git/atom?h=v1.1.0 2026-08-20T13:44:29Z 2026-08-20T13:44:29Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-20T13:44:29Z urn:sha1:987175105ead0ea78b960c0e638a81c6fd2384cf format never raises and returns an unparseable citation unchanged, so a gap degrades to today's behaviour rather than to a crash. The coverage test asserts separately that no shipped citation takes that path. verbatim is what --raw uses: an identity name table would still reformat punctuation and renumber, which would break byte-exact diffing against lectio. The existing citation-coverage walk (1970-2070) now also drives a round-trip check in the same pass: parse -> render -> parse must reach the same structure, using Book.default_spelling for names (Book.to_string returns the internal id, which is not a registered token and cannot be read back). Proved with a mutation: changing the default style's part_sep to a separator the parser does not accept reddened the round-trip case on 31 multi-part citations and nothing else; reverted.
