the variant's payload violates the branch type's refinement predicate

Example

Hint::Tag::refinement-failed means the Tag position contains a value that fails the refinement predicate. The example shows the failing form first, then one way to give the checker the missing structure.

# Bad: the variant payload fails the branch refinement.
Port.validate { tag = "Tcp"; value = -1; }

# Better: the payload satisfies the branch refinement.
Port.validate { tag = "Tcp"; value = 443; }
