"""Archived test classes split out of test/registered/distributed/test_dp_attention.py.

Originally registered with `register_cuda_ci(...)`. Moved here as part of
the per-commit pruning effort to keep the code reachable manually.
Run with `python3 test/manual/distributed/test_dp_attention_archived.py`.
