Start in R4/resources/bundle.go at lines 32-72 and inspect how the range loop handles entry while converting Patient, Encounter, and Observation resources. Check the existing project tests if available and verify that the analyzer warning is addressed without changing bundle filtering or resource conversion behavior.
