Start with srv/svc/artist.go at lines 280-303 and read how artistName is used in the range loop and passed into ArtistFilter and ArtistMeta. Determine whether the analyzer's reference warning represents a real bug, a mitigated case, or desirable behavior. Done means leaving the appropriate reaction classification on this issue.
