System tested

Evolutionary search over model merging recipes in parameter space and data-flow space.

Limitations

Utility-focused model development; not a system-safety guarantee for adaptive ecologies.

What the evidence does show

Automated search can discover high-performing combinations of open-source models and data-flow recipes.

What the evidence does not show

That automated model merging preserves safety properties under all derived compositions.
