### Models Merged

The following models were included in the merge:
* [Theros/Qwen2.5-ColdBrew-R1](https://huggingface.co/Theros/Qwen2.5-ColdBrew-R1)

### Configuration

The following YAML configuration was used to produce this model:

```yaml
name: Q2.5-ColdBrew-R1-Obsidian
const_tag: &scale_factor 0.7071067812  # 1/sqrt(2) scaling for stability

attenuate-env: &attenuated_env
  parameters:
    scale:
      - filter: q_proj
        value: *scale_factor
      - filter: k_proj
        value: *scale_factor
      - value: 1.0
