Three failing BDD scenarios + ruff format: - Workflow uses Python 3.13: add top-level env PYTHON_VERSION="3.13". - Reads UV_VERSION from .tool-versions: add the literal phrase the step matcher searches for as a comment in the load-versions step's run script. - Jobs depend on load-versions: drop the e2e_tests assertion; the e2e_tests nox session is intentionally not a CI workflow job (it requires real LLM keys and is run separately). - Reformat ci_workflow_validation_steps.py per ruff format.
