Thanks!  This is exactly the sort of source citation I was looking for.

I was confident that curses was not "part" of v7 because of these
factors.  (1) It wasn't in the manual; (2) archives of v7 in which we
now traffic as historical artifacts show no trace of it; and (3) the
story of its origin and development, even when distorted, doesn't place
it at the CSRC as far back as 1977/8.

But, if someone placed to know had claimed that it was, that would have
been a claim worth investigating.

Perhaps one reason my question can be read two ways is that I'm
interested in both aspects of the issue.

I'm trying to write a "History" section for the primary ncurses man page
and clean up other problems its documentation has, like a boilerplate
reference to "Version 7 curses" in many of its other man pages, which
repeatedly implies such a thing as a separate line of development from
"BSD curses" and "System V curses".  I've been dubious of that language
since first encountering it, but I want a good documentary record to
support my proposal to chop it out.

I see no evidence that you missed it.  :)
