Overview

Optional adapter for https://github.com/rameerez/organizations.

There is deliberately no runtime dependency on that gem. The adapter is selected only by a policy that says permit_acting_for_organization, and it talks to the public Membership association/API when capture occurs. A missing gem, wrong represented party type, missing membership, stale/insufficient role, or insufficient permission all deny authority.
