Avoid coercing missing SiteID, Decimal, and age boundaries to hardcoded defaults so payload intent is retained across test creation and reference range inserts. Align patient result age checks and OpenAPI examples with day-based age bounds, with feature coverage for create variants.
Use the base test row's RefType and ResultType to decide refnum/reftxt loading, and fetch discipline/department joins directly in getTestById to avoid redundant relation queries. Add feature coverage for show response behavior and include the related workspace cleanup changes so the branch state is consistent.
Rename legacy boolean helpers to is* naming across test definitions, patient models, and infrastructure data to match rest of backend.
Update controllers, models, migrations, seeders, tests, and OpenAPI docs/bundled spec so contracts and runtime align.
