Mark a required (must-approve) approver

1. Open the policy version (draft) in the editor.

2. On the stage, add (or open) the rule whose resolved user(s) must approve.

3. Tick the required checkbox on that rule's row.

4. Save and activate.

The stage now passes only when both the quorum mode is satisfied and every user resolved by every required rule has approved. If a required user has no remaining open task (expired, reassigned away, etc.), the stage is rejected.

Common pattern: stage with mode = any-n, mode_value = 2, three rules where one is marked required → "any 2 of 3 must approve, but the third one is mandatory."
