Summary

This PR updates the base Docker image digest for debian:13-slim.

---

Code Quality

• ✅ No commented-out code — Clean change.

• ✅ Meaningful variable names — BASE_IMAGE ARG is clear and consistent.

• ✅ DRY principle — No duplication introduced.

• ✅ No defects — Simple digest pin update, no logic involved.

• ⚠️ CLAUDE.md compliance — Per project instructions, updating BASE_IMAGE digest requires also updating the REFRESHED_AT date in the Dockerfile. This diff does not include a REFRESHED_AT update. The verify-dockerfile-refreshed-at-updated.yaml workflow is expected to catch this, but it should be addressed before merge.

  From CLAUDE.md: "Update REFRESHED_AT date to current date (YYYY-MM-DD format)" and "The verify-dockerfile-refreshed-at-updated.yaml workflow will fail if these are not kept in sync."

  Action required: Update REFRESHED_AT in Dockerfile to 2026-03-08.

---

Testing

• ✅ No new logic — No unit/integration tests needed for a base image digest bump.
• ✅ CI verification — docker-build-container.yaml and docker_test_script.sh will validate the image at build time.

---

Documentation

• ✅ README/API docs — No documentation changes needed for a digest update.
• ✅ No new complexity — No inline comments required.
• ⚠️ CHANGELOG.md — Not included in this diff. If this repo maintains a changelog, a base image bump entry may be warranted depending on project convention.

---

Security

• ✅ No hardcoded credentials — None present.
• ✅ No sensitive data — Clean.
• ✅ No license files (.lic) or AQAAAD-prefixed strings — Not present.
• ✅ Image pinned by digest — Using a SHA256 digest pin is a security best practice; avoids mutable tag issues.

---

Verdict

❌ Requires change before merge.

The REFRESHED_AT label in Dockerfile must be updated to the current date alongside any base image digest change, per project requirements. The CI workflow verify-dockerfile-refreshed-at-updated.yaml will likely block this PR until that is done.
