Inizia riproducendo il comportamento del copia-incolla nella Amazon Q CLI su macOS 15.5 con zsh, usando la versione di q segnalata, 1.12.5; q doctor e q restart sono gli strumenti diagnostici disponibili. L’issue è completata quando un incolla multilinea rimane intatto e non viene eseguito dopo soltanto la prima riga.
