MemberAvailabilityService keeps the CRUD and becomes a BusySource; the arithmetic it used to own now lives in kamo-shared-library. Call sites are unchanged — the delegations preserve every existing signature. restrictionMask carries a null weekday through to the engine rather than filtering it out: on WebinarChildOrgRestriction null means every day, and it is the common shape, so dropping those rows would empty the mask — which downstream means no narrowing at all.
