group.deleted

project_id is always null for group events. This is the final event you will receive for the given group_id.

When this fires

A group is deleted. Its permission and ability attachments are detached and its membership rows are removed; the people in it stay in the team but lose whatever the group granted.

Required ability

group:view — token must carry this at mint time to subscribe an endpoint to this event.

Caveats

No per-collaborator event fires: the members' group_user rows cascade away with the group, and group.members_synced is emitted only by an explicit membership sync.
Members of the group are not removed from the team; only the group and the access it granted go away.
