No there are hundreds of documents outlining genocidal practice and intentions. Specifically pertaining to gassing would be 20-30 documents + hundreds of witness statements and confessions + non-coerced confessions (eg in the eavesdropped recordings of German military Irving found in British archives or in Eichmann's pre-capture Argentina material which Irving also vouches for) + wartime sources + other suspicious things about all these camps which I have detailed exhaustively in this thread. An example here would be crematoria labor force reports, which have a thousand Jews working day and night for months at the crema to deal with what? the graph
@mrolonzo vouched for previously specifies on average less than 100 deaths per day after the typhus outbreak in 42, and no Jews (which he does not bat an eye at)

and we can contrast that to the zero evidence for the revisionist hypothesis, which is mass internment in German occupied USSR.
the reams you mention would be in reference to the large amount of evidence concerning resettled Jews in Romanian occupied USSR, so I have no idea what you're talking about
