name: zizmor

# Static analysis of the GitHub Actions workflows themselves — the surface the
# CodeQL pass does not cover. zizmor flags template injection, overly broad
# GITHUB_TOKEN permissions, unpinned actions, cache poisoning, and dangerous
# triggers. Findings appear under Security -> Code scanning alongside CodeQL.
#
# Report-only: with `advanced-security: true` the action runs zizmor in SARIF
# mode, which exits 0 regardless of findings, so this job never blocks CI —
# triage happens in the Security tab. Switch to gating later (e.g. a
# `min-severity` input) once the existing findings are triaged.
