[TUHS] v0 manpages of November 3, 1970? and earliest writing about Unix?

Several v0 manpages say 11/3/70 See https://github.com/DoctorWkt/pdp7-unix/commit/14a2a9b10bd4f9c56217234afb321… The commit message says "I've borrowed the V1 manuals from http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/man/man1 and changed them to reflect the PDP-7 utilities." Where did that 1970 date come from? Was it just made up? (Notice it is one year earlier, same day.) Maybe v0 didn't have any manuals? This was just an exercise in learning PDP7-Unix better? I understand they weren't in roff anyways. Also ... what is the earliest known date where we have some scanned/printed document? https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/ says "runs on the PDP-7 and -9 computers; a more modern version, a few months old, uses the PDP-11." but no specific date. The earliest date I see is from the 1stEdman / Dennis_v1 docs of November 3, 1971. That is a full set of docs. There must be something prior to that date. Anyone know of some early printed memo or other correspondence that mentions the work? Thanks, Jeremy C. Reed echo 'EhZ[h ^jjf0%%h[[Zc[Z_W$d[j%Xeeai%ZW[ced#]dk#f[d]k_d%' | \ tr '#-~' '\-.-{'
