Problem

Multiple sanctoral feasts can fall on the same date. They must be ordered deterministically by rank (and a stable tiebreak) before precedence runs, or resolution becomes nondeterministic.

Acceptance criteria

Same-date feasts are sorted by class then a stable secondary key
Sort is stable and reproducible run-to-run
Unit tests cover two and three feasts on one date
Tiebreak rule is documented in code

Notes

Determinism is required for the validation oracle to match.
