The 1-to-N lens for a frontend system that is already alive: the enemy is no longer building, it is ENTROPY — boundaries eroded by one "just this once" cross-import at a time, and the two graphs (component tree vs data dependency) drifting apart. Use when a frontend is in maintenance/scaling, onboarding more people, or showing rot (every change touches everything, the global store keeps growing, only one person dares touch the core). The one move: make the architecture SELF-ENFORCING, so it doesn't depend on everyone remembering the rules — because at scale they won't. Triggers on "the codebase is getting hard to change", "enforce architecture / module boundaries", "lint rules for imports / layering", "circular dependency", "this abstraction is everywhere / should I delete it", "dead code / unused exports / stale feature flags", "Conway's law / team structure", "design system / Storybook / component library", "onboarding / how long until a new hire ships". There is no exit; it is a steady state.
