Previously, linked membership checks only occurred if there was no membership application record. Now linked memberships are checked as fallback at every stage of the direct membership validation: - No membership application check linked - Indemnity not accepted check linked - No membership fees record check linked - Direct membership not active/expired check linked This ensures linked members see themselves as active across all member areas, detail pages, and booking forms (trips, courses, campsites, driver training, bush mechanics, rescue & recovery).
