detekt's TooManyFunctions, at exactly the threshold. Worth taking as the signal it is rather than suppressing: the file held the block MODEL — split a body, join it back, add an item, drop one — and the COMPOSABLES that draw it, which are two jobs that happen to share a data class. EditorBlock.kt keeps the model and is pure: no Compose imports beyond the types it stores, and testable on its own if it ever earns tests. BlockBody.kt keeps the four composables. afterEnter, withoutIndex and nextId become internal, since the UI half calls them across the file boundary now. That is the one cost of the split and it is small — same module, same package, and each says why in its doc.
