The owner's rule, in one place: MemberSecurityLevelPolicy. A team member holds Team Member or higher (it may be raised, never left below); a member holds Member only. Becoming a team member raises a lower level to Team Member and keeps a higher one; becoming a member sets Member, even from a raised level. - MemberService.changeMemberType: the one way to switch MEMBER <-> TEAM_MEMBER. It writes the discriminator, the member_team_member row and the security level together (native SQL, beside the existing updateMemberType). - **************** refuses a level the member's type cannot hold **************** an IllegalArgumentException with a reason). An echo of the level already held is not judged. - **************** refuses a level below Team Member. - **************** native SET SECURITY_LEVEL. No entity or schema change.
