"""
Batch-run the graph evaluation over every call that has audio sentiment data.

Purpose (v0.4.0 validation):
  1. Ground the fusion constants — collect text-vs-acoustic score pairs and
     escalation trajectories across calls so thresholds can be fitted to the
     observed distributions instead of asserted.
  2. Probe the workflow track for leakage/leniency — if expected-step pass
     rates are ~100% on every call including badly-handled ones, the checklist
     generation or the audit is compromised.

Usage:  python run_graph_batch.py [--results_dir results] [--only banking]
Output: results/{call_id}_graph.json per call + results/batch_summary.json
