Warning

Throw-away pipeline test. This PR comes from a test run of the post-materials pipeline on CMS post 1104 (a test copy of the tutorial). Do not merge. Please close it after the test is reviewed.

Code examples for the Python Sandbox: Run Untrusted Code in Docker and MicroVMs tutorial. Files live in the python-sandbox/ top-level folder, named after the article slug.

Generated from the tutorial markdown with the post-materials skill. The Python files and rootfs/sbin/run-job are byte-for-byte copies of the article's code blocks.

Notes:

• python-sandbox/ruff.toml extends the root pyproject.toml and sets quote-style = "preserve". Without it, ruff format --check would rewrite the PEP 701 nested same-quote f-string at the end of compare.py (f"...{result["exit_code"]}..." to result['exit_code']), which would diverge from the article.
• requirements.txt pins RestrictedPython==8.5, matching the post's dependencies field and the install command in the article.
