Executes HEC-RAS plans using RasControl class via HECRASController COM interface for legacy HEC-RAS versions (3.x-5.x). Handles COM lifecycle management, session tracking, orphan cleanup, steady/unsteady result extraction, and watchdog protection for Jupyter notebooks. Use when automating legacy HEC-RAS, extracting results from older versions, comparing across HEC-RAS versions, or needing COM-based automation that RasCmdr cannot provide. Triggers: RasControl, HECRASController, COM, legacy, HEC-RAS 4, HEC-RAS 5, win32com, steady results, unsteady results, version comparison, COM interface, legacy automation, 3.x, 4.x, 5.x, orphan cleanup, watchdog, session tracking.
