# Train ORPO for the 3-stage collaborative-vs-independent ablation.
#
# Configurations to produce:
#   (b) planner-INDEP ORPO + V/F SFT only          ← uses planner_INDEP only
#   (e) planner-COLLAB + validator-COLLAB + fixer  ← all three aligned
#   (d) planner-COLLAB + fixer (validator stays SFT)  ← same checkpoints; just swap at eval
# Total ORPO runs: 4 (planner_INDEP, planner_COLLAB, validator_COLLAB, fixer).

# Validator stays SFT-only this experiment — its outputs are too templated
# (only 4 informative pairs from 1431 questions, vs 1628 for planner). Skip its ORPO run.
# Methodology argument is preserved structurally; validator-collab is documented as future work.

# GPU 1 in background: fixer ORPO (shared between INDEP and COLLAB methods, since terminal)
