Copied field would replace another field.

Area 2, Values and types; not declinable; the next step is usually the agent's.

example
type TodoView = Output {    pick: [Todo.id, Todo.title, Note.title]}
text
error: `title` is already in `TodoView`, from `Todo` --> main.jadpo:2:33  |2 |     pick: [Todo.id, Todo.title, Note.title]  |                                 ^^^^^^^^^^ copied again  reason: A copied field never replaces another field, because a field added to a source type would then change this type unseen.  next: Remove `title` from one of them with `omit: [...]`, or write `title` as a field below them (agent)  rule: type.copy_clash  help: https://jadpo.dev/docs/errors/type.copy_clashcheck failed: 1 error, 2 files
