[synthesis] Agent decomposes tasks by feature or file without respecting dependency order

Decompose tasks by dependency graph, generating leaf-node dependencies first. Build the dependency graph from imports and references before generating code. Generate types and interfaces before implementations, utilities before consumers, data models before business logic.

Journey Context:
Naive task decomposition splits work by feature area or by file, then generates each piece independently. This fails because the model generates code referencing types, functions, or modules that don't exist yet, causing compilation errors that cascade through subsequent steps. v0's code generation follows a visible pattern: structure first, then styling, then interactivity—respecting dependency order \(structure is depended on by style, which is depended on by behavior\). Aider's repo map ensures the model sees dependencies before dependents. Cursor's multi-file edits follow import order. The synthesis: successful decomposition is topological-sort order, not feature order. The model needs to see and have already generated the dependencies of a module before generating the module itself. The tradeoff is that dependency-ordered generation requires a pre-generation analysis step \(building the dependency graph\), which adds latency. But it eliminates the 'undefined reference' class of errors that otherwise require multiple correction loops—often more total time than the upfront analysis.
