The Rule

One role per model. We build it, or we assure it. Never both. The company's governing rule for how it separates building from proving.

The Rule, versioned: for any given model, The Key 4 AI takes one of two roles, either building and standing behind it, or independently assuring it, never both for the same model at any time.
