Reason: This PR is linked to 1 new nightly CI failure in build #78700:
LM Eval Humming Act fp8/int8 (H100 - TEMPORARY)The
Qwen3-4B-mixed-quant-RTN-hummingserver crashed at startup (profile_run) with anAssertionErrorin the humming WNA4Int kernel dispatch (assert meta.a_dtype in cls.b4_allowed_dtypes), triggered fromCompressedTensorsWNA4Int.apply_weights. This PR modified exactly the files/functions in the crash traceback (compressed_tensors_wNa4.py,humming_utils.py).Failure is deterministic (server startup crash), not an infra/flaky issue.
