[synthesis] How should a code-generation product decompose a vague prompt into runnable UI code?

Run a planning model that emits a structured component breakdown, then a generation model that writes each file with explicit dependencies, then an execution sandbox that renders the result. Validate the rendered output, not just the AST.

Journey Context:
v0.dev's observable behavior shows it does not stream raw code from a single prompt. It first produces a design plan \(component list, props, data flow\), then generates files, then executes in a sandbox to produce a preview. The common mistake is to ask one model call to produce a full app, which fails on component boundaries and dependency conflicts. The preview is the test: if it doesn't render, the generation is wrong. Feedback loops must operate on rendered output, not just text diffs.
