Research direction

No source files, tests, or entry points are named. Start by reproducing the reported TypeError when pickling bytes to a file opened as text, then trace the relevant Python I/O and pickle paths. Done means the failure no longer presents a misleading error and the behavior is covered by an appropriate regression test.
