// without the in-body membership check any authenticated user could attach a
// freshly-created company to an arbitrary team_id (OWASP ASVS V8.2.1).
//
// These tests prove the check fires for non-members and passes for members
// (both owners and ordinary members), while preserving the NULL-team_id path
// for solo companies.
