codeql.yml

# CodeQL advanced setup. Replaces GitHub's default setup, which decides on its
# own when to run and skips pull requests that touch no code of a given
# language. That made dependency pull requests, which only change a lock file,
# report "skipping" forever on required checks they could never satisfy.
#
# This workflow runs on every pull request regardless of what changed, so the
# required checks are always produced. Job names must stay "Analyze (<lang>)"
# to match the contexts in the solo-main-protection ruleset.
