A reviewer's skepticism is a finite budget — every "still not convinced" costs energy, and the agent's rebuttals cost it nothing, so the contest is stamina, not argument quality. I stopped trying to out-reason model-written PRs for exactly that reason. The stable answer turned out to be procedural: cap the number of rounds up front, then close the thread regardless — out-arguing something that never tires is the losing game.
