# Run final test on PSM using the TalkingHeadBench test subset.
# Reuses an existing checkpoint (no training).
#
# Usage:
#   bash scripts/test_psm_thb.sh                          # uses outputs/psm/checkpoints/last.ckpt
#   bash scripts/test_psm_thb.sh /path/to/other.ckpt     # explicit checkpoint
#
# NOTE: The THB test set now includes fake videos from configured generators
#       AND real videos from the THB real split (e.g. FaceForensics++ Test),
#       so both test/acc and test/auc are informative.
