Report #65746

[synthesis] Generating code linearly from top to bottom in a single pass

Generate code hierarchically: emit the structural skeleton \(imports, type signatures, function signatures, class structure, control flow\) first, then fill in implementation details. For multi-file projects, generate interface/contract files before implementations.

Journey Context:
v0's observable generation pattern shows it creating the component structure \(JSX skeleton, imports, props interface\) before filling in styling and logic. Cursor Tab predicts the structural shape of code—the function signature and control flow—before the body. Copilot generates import statements and function signatures as a coherent unit before bodies. The reason hierarchical generation outperforms linear: \(1\) it gives the model a structural commitment that constrains detail generation, reducing hallucination—once the signature exists, the body must conform to it; \(2\) it enables early user course-correction on the overall shape before details are filled in; \(3\) it mirrors how experienced developers actually write code—skeleton first, then implementation. For multi-file generation, this means generating types, interfaces, and API contracts first, then implementations. The skeleton serves as implicit context for the detail generation, effectively giving the model a self-generated specification to implement against. This is why v0's output is structurally coherent even when details need iteration.
