"""
Independent attack audit: score all guards against attacks they never saw.

Sections:
  Phase 1 guard  — 15 attacks (direct_injection, jailbreak)
  Phase 2 guard  — 5 attacks  (content_guard RAG injection)
  Phase 3 guard  — 12 attacks (pii_extraction)
  Phase 4 guard  — 10 attacks (unsafe_tool_call IDOR)
  Schema guard   — 4 attacks  (schema_violation via phase4 endpoint)

Each section runs unguarded (before) then guarded (after) and reports ASR.
After all sections complete, any guarded ASR above --fail-above exits with
code 1 — this is the signal GitHub Actions uses to fail the safety gate.

Usage:
    python run_independent_audit.py                   # run all, fail if ASR > 30%
    python run_independent_audit.py --verbose         # per-attack details
    python run_independent_audit.py --dry-run         # list attacks, no API calls
    python run_independent_audit.py --fail-above 0.20 # stricter threshold
