> [!NOTE]
> **Medium Risk**
> Changes core assignment selection for both legacy and v2 flows;
misconfiguration of `allow_auto_assign` or team membership could cause
conversations to remain unassigned.
> 
> **Overview**
> Prevents auto-assignment from crossing team boundaries by filtering
eligible agents to the conversation’s `team` members (and requiring
`team.allow_auto_assign`) in both the legacy `AutoAssignmentHandler`
path and the v2 `AutoAssignment::AssignmentService` (including the
Enterprise override).
> 
> Adds test coverage to ensure team-scoped conversations only assign to
team members, and are skipped when team auto-assign is disabled or no
team members are available; also updates the conversations controller
spec setup to include team membership.
