Check each candidate's ID, code, defining attributes, standard status and - active status with `concept_get` and `concept_relationships` in this session. - Don't copy example IDs or pick from memory. A relationship or shared ancestor - means only what that relationship says; it doesn't prove two concepts match. -4. Pick the eligible candidate that keeps the most supported detail without adding - detail the source doesn't state [cdm]. A concept class tells you what to check, - not how to rank. `rules.yaml` lists defining attributes for RxNorm-family - classes [rxe]; the list is unordered and incomplete, and the concept's own - definition in the deployed vocabulary takes precedence.
