# Train PPO: fetch binaries → hyperopt → train → evaluate → upload.
#
# Usage:
#   argo submit --from=wftmpl/train-ppo -p binary-tag=dev-abc1234
#   argo submit --from=wftmpl/train-ppo -p binary-tag=latest -p train-epochs=100
#
# Thin wrapper around training-pipeline (templateRef) with PPO-tuned defaults.
# PPO uses 45 factored actions (5 exposure × 3 order × 3 urgency).
