Friction can be real without being sufficient for restraint
The paper tests whether self-generated costs from aggressive optimization imply that an adapting optimizer will naturally converge toward restraint. The tested inference fails in the declared model.
m = 0.1, a small constant action remains below the modeled trigger and earns a positive payoff.

This does not establish that adaptive optimizers generally reject restraint. It establishes only that the tested fixed-policy inference is insufficient in this model.
