+Both use `tokenizer_wikitext103.json`. Gate V's checkpoint is the shakedown run that Gate W continued from; it is
+kept because `serve.py` still names it as its default `--checkpoint`. Its 87.57 was re-measured over all 470
+validation windows, against the 87.85 recorded in the gate document: the difference is the evaluation batch
+size, not the weights, because `evaluate_tokens` averages per-batch means and so weights the final partial batch
+like a full one.
 
 Trained at batch 7, sequence 512, context 520, with MTP enabled and the loss weight annealed 0.3 to 0.1. The
 earlier 292.54 figure quoted for Gate Q is not comparable: it used WikiText-2 validation with a WikiText-2
