Isn't what the group is describing known as "straight photography"?
Years ago, we had the term "retouched" to descrbe the sort of things PS makes so easy today... What is wrong with using the term "retouched" ?
I kind of like the idea of a second "laying on of the hands"... retouching has always been understood to mean that something has been artificially changed....
I think you would only need to specify that in a straight photograph, retouching is limted to correcton of mechanical or process defects (such as dust) and that otherwise, the scene was "unmolested".
The US is still trying to catch up with us...

Now, their current site for passports offers these pointers...
"Do not retouch or otherwise enhance or soften photo."
"Copied or digitally scanned photos of photos will not be accepted."
"In addition, photos must not be retouched to alter the customer''s appearance in any way."
"Only original photographs are acceptable."
===
Reworking the above ideas I get:
Unmolested Photography:
An "Unmolested Photograph" is any original photograph that is neither enhanced nor softened and represents well the concept of straight photography. Specifically, it must not be retouched to alter the orginal scene's appearance in any way. The image must be a first generation image and not a copy or digital scan of another work.

Humm...
From Wiki:
Documentary photography usually refers to a type of professional photojournalism, but it may also be an amateur, artistic, or student pursuit. The photographer attempts to produce truthful, objective, and usually candid photography of a particular subject, most often pictures of people.
