Worked on the hiero-ledger/hiero-sdk-cpp repository, focusing on enhancing the accuracy and clarity of API documentation for checksum methods in the FileId, ScheduleId, and TopicId classes. Addressed a documentation bug by aligning method descriptions and return value explanations with the actual C++ code, reducing ambiguity for both contributors and downstream users. This effort improved onboarding and minimized misinterpretations of the API’s behavior. The work involved careful review and correction of technical documentation, leveraging C++ development skills and attention to detail. No new features were added during this period, but the documentation fix contributed to a more maintainable codebase.
