Run an antilogy on a plan, decision, claim, design, or code change: spawn a rigorous advocate and an adversarial critic IN PARALLEL against the same target, then adjudicate where they conflict and return a synthesis to the conversation. Use when the user wants to stress-test something from both sides before committing — "run an antilogy", "advocate vs critic", "steelman and attack this", or invokes /antilogy-verdict.
