name: CodeQL

# Documentation-only changes and private-submodule gitlink bumps (internal/, infra/,
# .claude/commands) cannot affect what CodeQL analyzes (C# and TypeScript), so they
# are filtered out rather than spending ~10 minutes to re-report an unchanged result.
# A gitlink bump reports the bare path ('internal', no trailing slash), which
# 'internal/**' does NOT match — both forms are listed. A commit that touches docs
# AND code still runs: GitHub skips only when EVERY changed path matches the filter.
# Same list as ci.yml except that each file leaves itself out; keep them in step.
