New munitor/docker_scan job (image-scan) in the pr-checks workflow of java-webapp, gradle-webapp, node-api and node-webapp: builds the app image and every supplemental image, runs the same Trivy 0.69.3 HIGH/CRITICAL --exit-code 1 scan as the release pipeline (same .trivyignore), stores the JSON results, and never pushes. build_push_supplemental gains push (default true, unchanged behavior).
