Lesson 2: Landmark designs, rebuilt and counted exactly

Module 7 · Lesson 2 · About 50 minutes · Needs: Lesson 1 of this module (the three wirings); Module 3, Lesson 5 (count_params); Module 4 (position kinds)

The situation

Sol 418 at Aurora Station. Lesson 1 settled which wiring suits which job. Now Kofi Mensah asks a sharper question: "Is the lab's base a real design, or something we made up? Show me where it sits among the published models, and prove each comparison with a count."

This lesson rebuilds the landmark transformers as presets of the package's ModelConfig, compares each with base, and checks every weight count against the published checkpoint. The running example is base's own config.
