group.created

project_id is always null for group events.

When this fires

A team owner or manager creates a new project group. Groups bundle projects so a collaborator can be granted a role scoped to a subset of projects.

Required ability

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

Caveats

Project memberships within the group are not embedded in this event; fetch the group from the API for the project list.
Group-scoped role assignments emit team.member.role_changed when assignments change.

group.updated — subsequent edits.
group.deleted — terminal state.
Group events overview — back to family overview.
