# Per-feast override of the chapter responsory's verse — some sanctoral # feasts replace the seasonal verse with their own (real Divinum Officium's # `winner{'Versum Prima'}` mechanism). Empty until milestone 4's sanctoral # propers store exists (LiturgicalDay.occurring is always [] until then, so # this table has nothing to key against yet) — see # src/hours/chapter-responsory.ts for how a lookup miss falls back to the # season table above. byFeastId: {}
