Worked on the aspect-build/rules_py repository to address issues with Bazel repository name handling when package versions included the "+" character. Focused on backend development using Bazel and Python, implementing logic to normalize "+" to underscores during repository name generation. This change prevented invalid-name errors and improved build robustness, particularly for edge-case version strings. Updated uv.lock-related logic to ensure consistent handling of plus-containing versions across repository rules and lock resolution. Added comprehensive tests to validate the new behavior and guard against regressions, enhancing reliability. The work centered on bug fixing and improving the stability of Bazel-based build processes.
