*	kernel: Colour and Subject shared vocabulary	Lukasz Kasprzak	2026-08-11	4	-0/+39
\| \| \| \| \| \|	The six liturgical colours and the Lord/BVM/saint/temporal distinction are common to both Roman forms, so they are shared closed variants rather than rite-parametric. Subject is so named because class is an OCaml keyword.
*	kernel(date): ISO-8601 rendering, validating parse, sexp converters	Lukasz Kasprzak	2026-08-11	3	-3/+42
\| \| \| \| \| \| \|	Adds sexplib and ppx_sexp_conv to the project and wires the ppx into the kernel library. Date's sexp form is an ISO-8601 atom rather than the opaque rata die, so data files stay human-editable and parsing revalidates the 1583..9999 domain.
*	kernel(computus): Easter-relative movable-feast anchors	Lukasz Kasprzak	2026-07-31	2	-0/+17
\| \| \| \| \| \|	Ash Wednesday/Palm Sunday/Ascension/Pentecost/Corpus Christi as Easter+/-N. Verified vs 2026 dates; exhaustive weekday invariants 1583..9999 (Ash Wed=Wed, Ascension/Corpus Christi=Thu, Palm/Pentecost=Sun).
*	kernel(computus): Gregorian + Julian Easter	Lukasz Kasprzak	2026-07-31	2	-0/+40
\| \| \| \| \| \| \|	Anonymous Gregorian (Meeus/Jones/Butcher) for OF+EF; Meeus Julian mapped to the proleptic-Gregorian date for future eastern rites. Verified vs known dates (2000/2024-27, 1583; Orthodox 2023/24) and EXHAUSTIVELY over 1583..9999: every Easter is a Sunday in [Mar22,Apr25].
*	kernel(date): proleptic Gregorian date, validated make + arithmetic	Lukasz Kasprzak	2026-07-31	2	-0/+81
\| \| \| \| \| \| \|	Hinnant civil<->days rep (1970-epoch rata die); make validates month/day and the 1583..9999 domain; of_rata/add_days are total arithmetic. Weekday, compare. Tested: known weekdays, leap boundaries, rejects; qcheck round-trip / add-inverse / weekday-cycle properties over random in-range dates.
*	chore: scaffold dune project (kernel lib + cli + tests)	Lukasz Kasprzak	2026-07-31	1	-0/+2
