name: CodeQL

# Shell and Dockerfiles have no CodeQL analyzer, so the analyzable surface in
# this repo is the GitHub Actions workflows themselves — CodeQL's `actions`
# support (GA since 2025-04) flags script injection, missing/over-broad
# permissions, unpinned actions and untrusted-input sinks in the workflows.
# Advanced setup: GitHub's "default" code-scanning setup must be OFF in repo
# settings (Settings → Code security → Code scanning → Advanced) or Analyze errors.

# Triggers are scoped to the ONLY paths this analysis reads (the `actions`
# language surface below + its config): a PR touching only shell scripts or the
# Dockerfile cannot produce different CodeQL results, and previously still ran a
# full ~1.5-3 min analysis. Safe because "CI Complete" (in ci.yml), not CodeQL,
# is the required branch-protection check — a skipped run can't deadlock merges.
# The weekly schedule still covers query-pack updates on an unchanged repo.
