## Behavioral notes
- This type participates in the `SAIF.Business.Claim.Person` public API surface.
- Persistence and validation behavior depend on the containing BOF object model when this type is a business entity or criteria type.*

## Constraints and usage notes
- Use the type through its owning BOF workflow or collection when applicable.
- Nested criteria and helper types are usually instantiated by the library rather than by external callers directly.*

> **Note:** Statements marked with `*` were inferred from code structure or contextual evidence.
