- gitleaks (via docker cp, dockerignore-agnostic) and hadolint scan every push/PR
- new ruff lint stage (ruff.toml pins known-first-party for host/container consistency)
- pytest --cov-fail-under=75 gate on the test stage
- scheduled Trivy critical failures now attempt an apk upgrade rebuild and open a PR

- ruff --fix/--format applied to existing code to start the gate clean
