# Does the wider cache COST anything at short context?
# retrain_corrected_cache.sh measured a prior cache switch going 75 -> 14-33 at
# ~4k while improving 1k and 16k. My 32k-cache result only covered 8k/16k/32k,
# so the regime where the known regression lives is UNMEASURED. This runs
# 1,024 and 4,096 under BOTH caches for both models.
