Despite your most heartfelt wishes, neither you nor I know what part of the Steele dossier is substantiated - or not. And we won't know for sure until Mueller releases his findings. I've read plenty of sources that numerous claims in the dossier are in fact true. You boldly state they are not. Perhaps you're right. We'll find out soon enough.
Comey said in his Fox interview that the dossier was still unverified at the time of his firing. Comey's credibility is in the *******, so who knows. But it doesn't matter, it served it's purpose by being the foundation for obtaining a FISA warrant. I doubt Mueller will mention anything in regard to the dossier in his report.
