| SheetSage2 attention adapters are merged into MERT2 in FP32 before BF16 conversion. Four audio frontend buffers remain FP32. Shared embeddings are recorded using MMGP tied-weight metadata. The conversion manifest records source revisions and tensor coverage. | |
| Place `SheetSage2_MERT2_bf16.safetensors` in `ckpts/sheetsage2/`. WanGP loads it only when source scoring is requested and releases the model after transcription. This checkpoint uses WanGP's local SheetSage2 implementation. | |
