You cannot ship what you cannot evaluate

The demo always works. The tenth thousand request is where AI features earn or lose trust, and you only know which if you measured.

Our baseline is unglamorous: a reference dataset, a rubric per failure mode, and a score that runs on every change. Guardrails come after — never instead.

Evaluation is not a phase you get to later. It is the thing that lets you move quickly without lying to yourself.
