Implement compile-time approach for a basic model

Try to implement the approach for a basic model, e.g. multiple multiplications and addition.

The pipeline is:
- Implementation
- Evaluation (use kinference infrastructure)
- Performance comparison

No files or tests are identified. Start by locating the implementation entry point and the kinference infrastructure used for evaluation, then clarify the scope of the basic model. Done means implementing multiple multiplications and an addition, evaluating the result through kinference, and comparing performance.
