"""Run failure classification pipeline on NegBioDB-CT database.

Three-tier detection:
  Tier 1: Terminated trials + NLP on why_stopped → bronze
  Tier 2: Completed trials + p > 0.05 → silver/gold
  Tier 3: CTO binary failure labels → copper

Prerequisites:
  - AACT data loaded (scripts_ct/load_aact.py)
  - Open Targets + CTO downloads (scripts_ct/download_*.py)

Usage:
    python scripts_ct/classify_failures.py [--db DB_PATH] [--data-dir DIR]
