# Security scanning (SAST). Runs on PRs/pushes to main plus a weekly
# schedule so newly-disclosed vulnerability patterns get caught even on
# code nobody's touched recently - this is GitHub's own recommended
# default cadence for CodeQL. dev is excluded since it's pushed to
# directly and frequently - see cicd-setup memory.

      # the source tree, since C# analysis works off compiled output.
