Model, Point, Input, And Action Design — Superseded

The Model/Point formula and Input Projection architecture is not the current Actor input, Action, or instantiation contract. The surviving product goals— readable learner state, explicit provenance, durable evidence, and domain-authored Sources—continue through ordinary Markdown, plugin-defined Source items, and the Actor/Action slice.

Use Actor And Action Implementation State for current behavior and the Discrete Math project for future domain shaping. Git history retains the complete prototype.
