UI evolution: typed bricks, creative proof, real flow
dogfood-proofInterface demand moves outward through fixtures, reusable libraries, intentional variants, evidence, and production pull. Fixture discoveries return inward as model and repository hypotheses that require a real producer.

Source provenance, target user, intended feeling, and constraints.
Executable demand hypotheses for states, relationships, commands, and scale.
The narrowest correct libs/app-client owner defines the stable contract.
Lock invariants; vary one or two dimensions across distinct expressions.
Checked-in accessibility, responsive, interaction, performance, ownership, and production-flow receipts derive readiness.
Apps bind real auth, data, actions, persistence, navigation, and telemetry.
Classify fixture demand and prove a real producer before claiming persistence.
