- Created membership_links table to associate secondary users with primary memberships - Created membership_permissions table for granular permission control - Added linkSecondaryUserToMembership() function to create links with validation - Added getUserMembershipLink() to check access via secondary links - Added getLinkedSecondaryUsers() to list all secondary users for a primary member - Added unlinkSecondaryUser() to remove links - Updated getUserMemberStatus() to check both direct and linked memberships - Created link_membership_user processor to handle linking via API - Created unlink_membership_user processor to handle unlinking via API - Added .htaccess routes for linking endpoints - Grants default permissions: access_member_areas, member_pricing, book_campsites, book_courses, book_trips - Includes transaction safety with rollback on errors - Includes comprehensive documentation with usage examples - Validates primary user has active membership before allowing links - Prevents duplicate links and self-linking
