 mixed-traffic screen. It remains prior-art evidence and therefore leaves the
 reviewer score at 5/10 until innovation itself wins the controlled ablation.
 
+The frozen MT-1 load-bearing screen fails decisively. Raw, norm-matched raw,
+and innovation all become nonfinite during epoch 1 and end at exactly 10.00%
+validation accuracy with NaN loss. They share clean source revision `412314e`,
+the same data order, initialization, four-times-RMS traffic, neutral predictor
+schedule, and `1.3271x` BP affine-MAC cost.
+
+The failure is not explained by the pre-endpoint mechanical invariants: the
+maximum initial traffic-ratio error is `4.77e-7`, the maximum post-warmup
+traffic-residual ratio is `0.139942` versus the frozen `0.25` ceiling, and all
+conditions use zero task-loss queries. Nevertheless all finite, accuracy,
+alignment, feedback-tracking, and usable matched-norm checks fail. MT-2 and the
+five-seed test confirmation remain untouched. This closes the controlled
+standard-ResNet accept recovery and leaves the reviewer estimate at 5/10.
