Worked on the google/fuzztest repository, focusing on enhancing input validation documentation and refactoring Sancov coverage handling. Improved code clarity and maintainability by adding detailed in-code comments to dispatcher.cc, clarifying how input pointers and sizes are validated for fuzzing callbacks. Led a foundational refactor of Sancov state management, consolidating coverage processing into a dedicated system and introducing a runtime API to support cross-framework feature emission. Addressed test flakiness by restoring explicit HasFlag behavior and removing implicit defaults. Utilized C++ and C, applying skills in API design, code refactoring, and runtime systems to deliver modular, maintainable, and reliable software improvements.
