Reading the eos field
248046 is <|im_end|>, the token the Qwen3.5 chat template ends every assistant turn with.
Checkpoints missing it do not stop at end-of-turn and overrun the context window, so their
eval numbers are a floor, not a measurement — compare them only against other checkpoints
with the same eos status, or re-package before evaluating.
Cell note: best cell in the sweep
