⚡ Recommended focus areas for review API Design Verify that removing async from these endpoints is the correct approach for handling Pyro calls. Consider if there are alternative patterns that could maintain async without blocking the event loop. Documentation The FIXME comment about proper return type should be addressed before merging. Return types should be properly specified for API endpoints.
