Worked on stabilizing the fuzzing workflow in the google/clusterfuzz repository by addressing a critical bug that caused assertion failures when the quarantine corpus was empty. Using Python for backend development and testing, implemented a targeted fix that skips the rsync_from_disk() call during pruning if the quarantine corpus is empty, thereby reducing the risk of pipeline crashes. Extended regression coverage by adding tests to the Coverage Client Job to verify correct behavior in this scenario. Delivered changes with a focused scope and clear commit messages, reinforcing maintainability and reliability for continuous fuzzing campaigns and production workloads within the project.
