# Description of Changes This pull request introduces several improvements focused on security and reliability in both the Docker build process and the backend API. The most significant changes are the use of digest-pinned Docker base images to ensure reproducible builds, safer handling of user-provided filenames in error messages, and a switch to more reliable dependency installation in CI workflows. **Docker image security and reproducibility:** * All Dockerfiles now use digest-pinned base images (e.g., `node:20-alpine@sha256:...`, `gradle:8.14-jdk21@sha256:...`, `alpine:3.22.1@sha256:...`, `nginx:alpine@sha256:...`) to guarantee build consistency and protect against upstream image changes.
