📝 WalkthroughWalkthroughAdds end-to-end YuE2 support. The changes define YuE2 latent and audio VAE behavior, implement text and acoustic conditioning, add the acoustic diffusion transformer, detect and register YuE2 checkpoints, and expose generation nodes. Startup loading now includes the YuE2 CLIP type and extension. Priority: ➖ Normal Merge Risk: 🟡 Moderate · up to YuE2 generation can retain resources across runs, while valid latent-node inputs can immediately exhaust available memory. These availability risks should be resolved before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@comfy_extras/nodes_yue2.py`:
- Line 86: Update EmptyYuE2LatentAudio to align its seconds limit with the
supported YuE2 duration and validate the product of batch_size and computed
frames against an explicit maximum before calling torch.zeros. Reject or
otherwise stop oversized allocations while preserving valid latent creation.
In `@comfy/text_encoders/yue2.py`:
- Line 212: Update _acoustic_conditioning to wrap its _prefill chunk-processing
loop in a try/finally, and call comfy.model_prefetch.cleanup_prefetch_queues()
in the finally block so prefetch queues are cleared after both successful and
failed execution.

Learning: In ComfyUI’s internal supported model implementations (comfy/supported_models_base.py and comfy/supported_models/*.py), ensure model classes do not override matches() in their own class bodies. All supported models should use BASE.matches() for backward compatibility; if a future change introduces a matches() override in a subclass, treat it as a backward-compatibility risk and require additional review/testing to confirm behavior remains consistent with BASE.matches().

Bound the EmptyYuE2LatentAudio allocation.
seconds allows up to 1000 and batch_size up to 4096. With FRAMES_PER_SECOND = 25, line 86 can allocate 6,553,600,000 elements before sampling: 12.2 GiB with fp16 intermediates or 24.4 GiB with fp32. The 360-second bound on YuE2GenerateMusic does not constrain this separate latent node. Enforce an explicit batch_size * frames limit before torch.zeros, and align the latent node’s duration bound with the supported YuE2 duration.

its seconds limit with the supported YuE2 duration and validate the product of
batch_size and computed frames against an explicit maximum before calling

Add prefetch cleanup to _acoustic_conditioning.
When prefetching is active, Llama2_.forward adds each queue to the process-wide PREFETCH_QUEUES. _acoustic_conditioning calls _prefill for each chunk but does not clear these queues, so prefetch state can remain after success or failure. Wrap the loop in try/finally and call comfy.model_prefetch.cleanup_prefetch_queues() in the finally block.
