This version upgrade will break the Docker build. The COPY instruction on line 41 uses a hardcoded path with the old Python version (3.13) for both the source (from this builder stage) and the destination (in the runtime stage defined on line 26).

# services/arms/judge/Dockerfile:41
COPY --from=builder /usr/local/lib/python3.13/site-packages /usr/local/lib/python3.13/site-packages

With the base images updated to python:3.14.1-slim, the site-packages directory will be at /usr/local/lib/python3.14/site-packages. The COPY instruction will fail because the source path /usr/local/lib/python3.13/site-packages will not exist in the builder stage.

To fix this, the version number in the path on line 41 must be updated to 3.14 for both source and destination.

A better long-term solution would be to use an ARG for the Python version to avoid this kind of issue in the future. For example:

ARG PYTHON_VERSION_SHORT=3.14
ARG PYTHON_VERSION_FULL=3.14.1
FROM python:${PYTHON_VERSION_FULL}-slim as builder
...
COPY --from=builder /usr/local/lib/python${PYTHON_VERSION_SHORT}/site-packages /usr/local/lib/python${PYTHON_VERSION_SHORT}/site-packages

This way, you only need to update the ARGs at the top of the file.
