# Two things here:
# 1. Advisory diff — ruff + ty diagnostics as a diff vs the target branch.
# Posts a Markdown summary and a PR comment. Exit zero always.
# 2. Blocking ``ruff check .`` — enforces the explicit rules in
# ``[tool.ruff.lint.select]`` (currently PLW1514). Failure blocks merge.
# Separate job so the advisory diff still runs and posts even when
# enforcement fails.

This PR changes CI-sensitive files (eslint config, workflow YAMLs,

js-autofix job executes and pushes to main.
A maintainer should verify:
- no new eslint rules with custom \`fix\` functions that write outside linted paths,
- no workflow changes that widen permissions or remove guards,
- no composite action changes that alter what gets executed.
After review, add the \`ci-reviewed\` label and re-run this check."
