Small projects forgive a lot. When the codebase has ten components and two developers, inconsistency is manageable. You know where everything is. You remember the decisions you made. The AI output varies a little but nothing breaks badly enough to slow you down. Then the project grows. More features. More developers. More sessions with GitHub Copilot. And the inconsistency that was manageable at ten components becomes a real problem at a hundred. What scaling without rules actually looks like It does not happen dramatically. It happens one session at a time. A new feature gets built slightly differently from the last one. A new developer joins and their Copilot sessions produce output that works but does not match the existing patterns. The components folder grows but the structure inside it becomes harder to navigate. Nobody made a bad decision. Nobody cut a corner. GitHub Copilot just kept inventing a slightly different standard every session because no rule told it to do otherwise.…
