"""Spike 8: Test Pyodide/WASM sandbox for Smolagents.

This spike validates:
1. Whether Smolagents has Pyodide executor support
2. If not, what sandbox options are available
3. Security comparison with LocalPythonExecutor

Run: uv run python spikes/spike_08_pyodide_sandbox.py

Note: This spike may fail if Pyodide support isn't available.
      That's useful information - we'll document what IS available.

Based on this spike:

1. LocalPythonExecutor is the DEFAULT and RECOMMENDED sandbox
   - Blocks dangerous imports (os, subprocess, etc.)
   - Blocks file I/O operations
   - Good enough for our use case

2. Pyodide/WASM executor:
   - May not be available in current smolagents version
   - Would require additional setup/dependencies
   - DEFER until there's clear need

3. Docker executor:
   - Available but requires Docker daemon
   - Overkill for our use case
   - SKIP as planned

RECOMMENDATION: Stick with LocalPythonExecutor (default).
               Don't pursue Pyodide unless security audit demands it.
