The multi-file iteration problem is the exact wall most people hit after the first demo works. Generating a single feature in isolation is easy; keeping context coherent across 10+ files while iterating on user feedback is where things fall apart. Curious what you landed on for state management across sessions — that tends to be where phone-first tools lose fidelity fast when the project grows beyond 3-4 components.
