Migrate Callers Then Delete Legacy APIs

Update tests to assert the new contract, and delete tests that only protect pre-refactor implementation details

When this applies:

No external users depend on backward compatibility
The project can absorb coordinated breaking changes
The new API is part of a simplification or refactor initiative
