Parse, don't validate - using sealed classes for type-safe validation and state representation. Model valid/invalid states explicitly, validate at boundaries, operate on valid types internally. Use when implementing validation with sealed classes, modeling valid/invalid states, or applying parse-don't-validate patterns in Kotlin. The pattern is transferrable to other languages, though the mechanism will differ.
