DTM.9:5.3 - A successful restriction may leave another continuation route
In the selective-action regime, A=0.45 and a=0.9. Consider a hypothetical rare alternative B* that is unaffected by v and has response sensitivity 0.1 instead of 0.2. Its initial growth rate under the same resource account is:
(1−0.45) − 0.3 − 0.1×0.9 = 0.16.
The positive value establishes a possible weakness of this intervention under those assumptions. It does not predict the appearance of B*, its frequency or an adversary’s intention. The next question is whether that alternative has a plausible construction and whether a feasible observation or action addresses it.
A changed variant may also be more useful rather than more harmful. DTM.1 must establish its consequences afresh; inherited suspicion is not an evaluation.
