Research direction

The issue body provides only a RuntimeError mentioning tensors on cuda:1 and cuda:0; it names no files, tests, or entry points. Start by locating the execution path that produces the error and reproduce it with the reported device mismatch. Done requires identifying the affected path and verifying that the error no longer occurs.
