Caveats

Membership detail (which projects belong to the group) is not embedded; fetch the group from the API to determine what changed.
Group-scoped role assignments are unchanged by membership tweaks but the effective access surface changes immediately.

group.created — predecessor.
group.deleted — terminal state.
