The OptimalService singleton published the instance before initialize() finished, so a concurrent caller could observe _initialized=False and hit "OptimalService not initialized" during RAG indexing. Build the instance, initialize it, then publish under a lazily-bound asyncio lock so all callers share a fully-initialized singleton. roboco_kb_search forwarded the legacy alias index_types=['docs'], which is not a valid IndexType value (the enum value is 'documentation'), producing a 400 at the route. Normalize the alias in the client before the request is sent and fix the misleading tool docstring. The mentor route let exceptions from mentor.ask escape as a bare 500 that masked the real cause. Catch, log the true upstream error with stack, and surface it in the response detail so failures are diagnosable.
