codeql.yml

# CodeQL advanced setup.
#
# Replaces the repository's CodeQL *default* setup, which only analyses a pull
# request when it touches files relevant to the configured languages. A PR that
# changes only docs or dependency manifests produced no analysis at all, while
# `master` still carried one per language — so the `code_scanning` branch rule
# could not diff the two sides and reported "configurations not found".
#
# Running here, with no path filter, guarantees both configurations exist on
# every pull request. The categories below must keep matching the ones recorded
# on `master` (`/language:actions`, `/language:rust`) for that diff to work.
