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=v0.1.0 2026-08-11T10:15:44Z 2026-08-11T10:15:44Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-11T10:15:44Z urn:sha1:2e3697b5ce7338568a67531d07a5528f0de1da22 Entries sort by slug so equal layers serialise identically. The by-date index is built once per layer rather than per year, since fixed dates are year-independent; a full-domain sweep would otherwise rescan every entry for every day. load turns parse and validation failures into result.
