6 arms x 7 runs x 7 rounds vs real DrussGT on one frozen binary (2747ebd). Validity check PASSES: g100 (fixed gain 1.0) is statistically indistinguishable from control (dmg p=0.65, wins p=0.62, ALL hit rate +0.04pp p=0.92; zero [bb] lines = provably no correction). Fixed gains above 1.0 LOSE at 300+: gfix150 -94 dmg/run (p=0.0006), 4/49 vs 16/49 wins (p=0.009), -3.85pp at 300-450 (p=0.0006) and -2.25pp at 450+ (p=0.0023). The hypothesis arm ghi (learner allowed above 1) is directionally positive but inside the MDE (+14.3 dmg/run p=0.41; +0.83pp at 450+ p=0.35). Kill the gain axis in both directions. Includes the mandatory correction notice: Phase 1's [1,1,1,0,0] is LIVE-REFUTED by140fe25, and the standing rule that offline is veto-only / live decides.
