A companion paper argued that, if technological civilizations are common, the Great Silence is kept by resident self-replicating probes of several lineages, held in mutual restraint by the cost of exposure. This paper asks what follows for a civilization that has reached that conclusion about its own system. We build the threat model: when resident probes act, how a strike is delivered through a gravitational keyhole by a push of micrometres per second years ahead, why the probes stay, and what happens when two lineages meet on one rock. We test the model against Earth's record and the interstellar objects so far, and pre-register criteria for the next. Within the model, three decisions minimize hazard in every branch: observe passively, do not transmit, do not launch replicators before dispersal. A strategy that exploits the watchers' lag fails against watchers that forecast from experience, which gives the general principle: facing a far better informed observer, change its incentives rather than deceive it. Two levers survive, survey completeness, which raises the cost of the quietest strike, and visible restraint on replicators, which lowers the value of removing the civilization. A small game shows that fewer lineages regarding the civilization as a threat can make it less safe, unless enough others would punish an unjustified strike.
This is a conditional theoretical analysis: it assumes the ecology proposed in the companion paper and derives what would follow for a civilization that accepted it.
