"""
Test suite for injection defense — all 3 layers.

Covers:
  Unit tests:
    1. _extract_text_from_args() for all tool arg shapes
    2. injection_tool_guard() — known injection blocked, clean allowed
    3. Mode behaviour (block / warn / log)
    4. Super agent bypass
    5. Agent config overrides (enabled=0, min_severity)
  E2E / integration tests:
    6. Direct user injection → tool guard blocks
    7. Tool argument injection → blocked with correct error message
    8. File-borne injection → result flagged/quarantined (Layer B)
    9. False positive: "instruksi" in legitimate context → NOT blocked
   10. Message guard: user injection + check_messages=1 → system warning injected
