Round-end reward = cumulative totalScore/50 grows unboundedly with battle length; long battles (5841 rounds) blew the critic's value scale: vLoss 10-30 during the 60-round cert, 353 at battle-1 round 1, 25745 by round 3871, policy drift to 0/6 wins. 60-round battles reproduce the certified regime: bounded value targets, fresh bot process per battle (clears thread state).
