The linked documents from that substack author discuss artifacts, adjudication, the machines, hard drives, show photos of people who manipulated files, lists of deleted files, voter registrations, and more.

Each issue is also categorized as to how likely it was to have occurred, and how critical it would be to the result if it had.

I say this not as an advocate that the links are the final representation, but because I think the leaked drafts have some level of legit origin, and as such they give us some indication of what will be discussed tomorrow.

Knowing the draft now lets us move around the final report a bit more quickly tomorrow.
