vLLM 0.29 renamed the audio attention projection from qkv to qkv_proj, and
its stacked mapping now rewrites checkpoint q_proj/k_proj/v_proj onto that
name. Omni subclasses the upstream audio attention and mirrors its __init__
to add quant_config, so it kept building self.qkv and weight loading died
with "There is no module or parameter named layers.0.self_attn.qkv_proj in
Qwen3OmniMoeAudioEncoder ... available: self_attn.qkv.weight". The inherited
forward calls self.qkv_proj too, so the old name broke both paths.
This is a second, independent cause behind the Omni Accuracy Test failure:
the shutdown-timeout signature also appeared in that job, which is why the
earlier pass attributed it solely to the shutdown fix. Both builds 3009 and
3010 carry this weight-loading error, so it predates that pass.
Not reproducible locally: it needs the 30B checkpoint. The rename mirrors
upstream Qwen3OmniMoeAudioAttention exactly, and the 20 Qwen3-Omni unit tests
still pass.
