PR Code Analyzer ❗

AI-powered 'Code-Diff-Analyzer' found issues on commit 09e9fb3.

Path	Line	Severity	Description
.github/workflows/publish-maven-snapshots.yml	55	low	Addition of `-Dsandbox.enabled=true` JVM system property to the Maven snapshot publish command. Unlike `-P` (Gradle project property), `-D` sets a JVM system property that could alter runtime behavior in ways not visible in this diff. The effect depends entirely on how `sandbox.enabled` is handled in the build or application code. Maintainers should verify this flag does not alter publish targets, artifact content, or enable hidden code paths during the publish pipeline.
