Worked on enhancing the API surface of the freeflowuniverse/herolib repository by making the RValue type publicly accessible in resp_model.v. This change allowed external modules to interact directly with RValue, improving integration possibilities and supporting broader ecosystem development. The approach focused on careful API design and thoughtful type system considerations in the V programming language, ensuring versioned and traceable modifications. No major bugs were addressed during this period, as the primary contribution centered on expanding public API capabilities. The work demonstrated attention to interoperability and developer productivity, with all changes documented through clear, traceable commits for maintainability and future reference.
