The framework repairs repository-level RTL bugs by reproducing a failure, tracing its waveform with structured queries, and propagating candidate edits across connected design sites. It replays the original scenario to check whether the violation is resolved. With DeepSeek V4 Flash and the same OpenHands SDK scaffold, it resolves 312 of 388 tasks, versus 273; results exclude 29 unadapted OpenTitan tasks.
