The broker example contains two different kinds of rationale: a workload assumption (a few jobs per minute) and an owner constraint (no additional hosted service). I would record those separately, with a condition for revisiting the assumption. If traffic grows, the next session can flag that the original sizing no longer holds without treating that as permission to introduce the rejected service. A test could give a fresh session the same decision record plus changed traffic, and check that it proposes a review instead of silently reversing the decision.
