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

example
type OrderId = Uuid {}type ProductName = Text {    max_length: 120}function order_for(name: ProductName) -> OrderId {    return OrderId(name)}
text
error: `OrderId` can't be built from `ProductName` --> main.jadpo:8:20  |8 |     return OrderId(name)  |                    ^^^^ this is `ProductName`  reason: `OrderId` is built on `Uuid` and `ProductName` is built on `Text`; a constructor converts only between types with the same representation, re-checking the rules.  next: Pass a value built on `Uuid` (agent)  rule: type.constructor_input  help: https://jadpo.dev/docs/errors/type.constructor_inputcheck failed: 1 error, 1 file
