DTM.4:4.4 - Distinguish a temporary displacement from a changed law

Model what the contemplated action changes. A one-time alteration of current use changes an initial condition. Continuing support, a compatibility adapter or a revised recognition rule can change a rate or a dependence. A newly available variant changes the candidate set.

Follow the trajectory during the action and after its removal. Ask whether the post-action state remains in the same region of attraction, enters another one, or encounters a different law because capabilities, resources or variants have changed.

For an intended return, identify the route and means needed to realize it. Lowering a parameter is insufficient if a necessary alternative has been lost or an endpoint is invariant under the model. Use C.36.RP and the relevant domain method to obtain an unavailable contribution; do not invent it as a free change in the state variable.
