Start with robot/robot.go lines 66-91 and inspect how the request entries are stored and later used. Check whether each appended request retains the intended loop entry or the same range variable reference, then compare the behavior with the analyzer report. Done means reacting to classify the finding as a bug, mitigated, or desirable behavior.
