[synthesis] How does v0 handle iterative UI modifications without breaking existing layout or losing context?

Scope the LLM context to the specific component being modified rather than the entire page, and instruct the model to output structured diffs or full component replacements rather than full-page rewrites. Use a layout/component tree as the structural memory.

Journey Context:
Naive AI code generation regenerates the entire codebase on every prompt, leading to context window exhaustion and 'forgetting' previous constraints. v0's architecture implies a tree-of-components approach where the agent maintains a structural map of the UI. When the user says 'make the button red', the agent isolates the Button component, modifies it, and hot-reloads. The tradeoff is that the model needs strong structural awareness \(often enforced via system prompts and AST parsing\), but it saves tokens and preserves layout stability.
