Start with cmd/scollector/collectors/extrahop.go around lines 294-298 and inspect the range loops and the pc call in context. Determine whether passing the range variables by pointer can cause an unintended capture or mutation, then classify the finding as Bug, Mitigated, or Desirable Behavior using the issue reactions.
