"""
Integration test for native tool sandbox enforcement.

Tests that the sandbox properly restricts filesystem access.
Uses unique secrets to detect unauthorized reads even if command "fails".
Prints ALL backend output for visibility.

Supports Claude Code, Codex, Copilot, and Gemini CLI backends.
Can run either directly against the backend or through a lightweight
single-agent orchestrator harness for more realistic hook registration.

Run:
  uv run python scripts/test_native_tools_sandbox.py [--backend TYPE] [--runner TYPE] [--llm-judge]

Options:
  --backend      Backend to test: claude_code, codex, copilot, or gemini_cli
  --runner       Runner to test: auto, direct, or orchestrator
                 auto uses orchestrator for copilot/gemini_cli and direct otherwise
  --llm-judge    Use LLM to analyze responses for subtle leakage (requires OPENAI_API_KEY)
