In May 2025, AJ Rpeggio enhanced the aspect-build/rules_py repository by implementing group-based ownership for image layers within the py_image_layer rule. He introduced a new 'group' attribute, allowing explicit specification of group owners for image assets, which improved asset governance and reduced configuration errors. The technical approach involved extending Starlark-based Bazel build rules to support attribute-driven configuration, ensuring consistent ownership semantics across generated layers. AJ also updated the project documentation to guide users in leveraging the new feature. This work demonstrated proficiency in Bazel, build systems, and Starlark, delivering a maintainable solution that supports reuse and clarity in build configurations.
