/** Version 4 keeps v3's gate but scores a completed wrong answer in either arm
 * as a correctness result; only execution, scope and metric failures invalidate
 * a trial. An OFF wrong answer no longer fails the comparison.
 * Version 3 gates supported behavior, plus the comparison for fixtures that
 * declare a gate (dedicated tools: correct output and 20% fewer Bash calls,
 * replacing v2's zero Bash in every ON trial). Other comparisons stay research-only.
 * Version 1 required efficacy lift. Never reinterpret recorded failures of earlier versions.
