# Defensive long-training run for LightweightTransformer.
# Motivation: the 30-epoch screening showed Lightweight peaking at
# median epoch 20/30 (per inspect_sweep) — i.e. still improving when
# the budget cut off. To rule out "the gap to Vanilla is just an
# undertraining artifact" we re-train ONE config (d=128, h=4, L=1)
# at 200 epochs with everything else identical.
#
# Output namespace: sweep/oc150_longtrain/lightweight_transformer_d128_h4_L1/
# So inspect_run --group oc150_longtrain picks this up alongside (or
# in place of) the 30-epoch oc150 entry without overwriting it.
