* ci: add security scanning suite and governance
Consolidates the security CI work into one reviewable change. Adds, as
separate workflow files under .github/workflows/:
- secret-scan.yml gitleaks (pinned + checksum-verified), full history
- workflow-security.yml actionlint + zizmor, audits the workflows themselves
- dependency-review.yml PR dependency gate + advisory pip-audit
- container-scan.yml hadolint (blocking) + Trivy image scan (advisory)
- codeql.yml CodeQL for Python and JS, main + weekly
Plus .github/dependabot.yml (pip/npm/actions/docker), .github/CODEOWNERS,
and docs/security-ci.md explaining each check and the one-time settings.
All additive: no existing files are modified. Actions are pinned to commit
SHAs, tokens default-deny (permissions: {}), advisory scans never block,
and SARIF upload is gated to push so fork PRs do not fail on a read-only
token. Composes with the correctness CI in #1015.
* ci(security): isolate Trivy from the Dockerfile lint gate
Address review on #1314 (points 2 and 3).
container-scan.yml now runs only hadolint (the blocking Dockerfile lint)
and keeps the broad pull_request + push:[main] trigger so the required
check always reports and never hangs a PR.
The advisory image scan moves to container-trivy.yml, split by event:
- pull_request / workflow_dispatch: build and scan under contents:read
only, no SARIF upload. The image build runs PR-supplied Dockerfile
instructions, so this path holds no write scope.
- push to main: build, scan, and upload SARIF with security-events:write.
Only this trusted path is granted write.
This stops PR jobs from requesting security-events:write they never use,
and a paths-ignore (matching docker-publish.yml) skips the image rebuild
on docs-only changes.
docs/security-ci.md: correct the trigger description to "every pull
request and every push to main", matching the workflows and the existing
ci.yml convention.
Verified locally: zizmor --offline --min-severity=low and actionlint are
clean on the changed and new workflow files.
