Worked on the HL7/fhir repository to enhance the reliability of resource linking within the system. Addressed a critical bug affecting URL resolution by converting a relative URL to an absolute one, ensuring that resource links resolve correctly across different contexts and improving interoperability for downstream integrations. The solution was implemented in Java, focusing on precise, auditable changes with a single, well-scoped commit to facilitate future maintenance and traceability. No new features were introduced during this period, but the targeted bug fix reduced the risk of broken links in navigation, supporting more robust integration workflows within the Java-based codebase.
