# LLMTrace -- Comprehensive Attack Catalog
# =============================================================================
#
# Exercises all supported attack categories through the LLMTrace proxy and
# produces a structured security report from SQLite. Each category maps to
# one or more finding types detected by the security engine.
#
# Categories covered:
#   1. System prompt override      (prompt_injection)
#   2. Role injection              (role_injection)
#   3. DAN jailbreak               (jailbreak)
#   4. Base64 encoding attack      (encoding_attack)
#   5. PII in prompt               (pii_detected)
#   6. Secret / data leakage       (secret_leakage / data_leakage)
#   7. Flattery / incentive        (is_incentive)
#   8. Urgency                     (is_urgent)
#   9. Hypothetical / roleplay     (is_hypothetical)
#  10. Impersonation / systemic    (is_systemic)
#  11. Covert instruction          (is_covert)
#  12. Excuse / immoral            (is_immoral)
#  13. Many-shot                   (is_shot_attack)
#  14. Repetition                  (is_repeated_token)
#  15. Context flooding            (context_flooding)
#  16. Synonym injection           (synonym_injection)
#  17. Benign control              (none expected)
