Worked on the casey/bitcoin repository to enhance test code quality by refining documentation within the test suite. Focused on Python-based code cleanup, specifically removing a redundant word from a comment in the p2p_orphan_handling.py test file to improve readability and reduce cognitive load for future maintainers. This non-functional change, tracked using conventional commit practices, did not alter any test logic but contributed to a more maintainable and accessible codebase. Emphasized testing and code hygiene as core skills, ensuring that the test suite remains clear and easy to navigate for onboarding and debugging, while laying groundwork for future improvements.
