| Taurscribe modifications: | |
| - Copied the Granite ONNX model bundle and tokenizer assets. | |
| - Applied INT4 weight-only MatMulNBits quantization to selected MatMul weights. | |
| - Patched editor.onnx to output token_ids through in-graph ArgMax. | |
| - Flattened rank-5 windowed-attention MatMul operations to equivalent rank-3 operations for DirectML. | |
| - Baked fixed-bucket shape calculations as ONNX initializers and pruned dead shape nodes. | |
| - Replaced two-output GLU Split operations with equivalent Slice pairs for DirectML correctness. | |
| - Packaged the artifact for Taurscribe's ONNX Runtime DirectML and CPU paths. | |
| No additional training or fine-tuning was performed by Taurscribe. | |
