# Per-checkpoint eval worker (1 GPU). Polls ADAPTER_REPO for new checkpoint-N
# dirs and evaluates each on a fixed N_TASKS subset of the held-out test split,
# writing eval/<checkpoint-N>_results.json + a rolling eval/summary.json.
#
# Expected env:
# HF_TOKEN (secret) hub access + sandbox Jobs
# ADAPTER_REPO (env) repo the training job pushes checkpoints to
# N_TASKS (env) test tasks per eval (default 100; same subset every time)
