Open main.go at lines 236-255 in the linked estafette-letsencrypt-certificate commit and read the range-loop analyzer guidance. Determine whether passing the referenced loop value to copySecretToNamespace can produce incorrect behavior, then leave the requested Bug, Mitigated, or Desirable Behavior reaction. Done means one classification is recorded.
