#!/bin/bash
# =============================================================================
# Best-first eval driver for the POLICY-ONLY GOLD checkpoints.
# Sibling of run_bestfirst_eval.sh; evaluates only the gold finetuned models
# (base 0/1.pt are already covered by run_bestfirst_eval.sh).
#
#   eval set:  every policy-only-gold epoch_2.pt (final) + epoch_1.pt (mid)
#              under train_policy_only_gold/.
#   eval:      bestfirst_search.py, extrinsic-95, --max-pops 4000, --timeout 600.
#              Action cap OFF (faithful to MCTS).
#
# Uses all 4 GPUs, one eval per GPU at a time.
