The source places an important qualification on many of the state-change invalidators in this sequence: if the conflicting event occurs before the final sitting has been completed for the duration of Tashahhud, the prayer is invalid according to the stated rule.
For some events occurring after that final sitting, the Hanafi authorities record disagreement because the legal exit from prayer is itself a separate issue. Therefore the course does not flatten every technical case into “it always invalidates at every moment.”
