Matt,
You're information on AGC4 assembler language is a bit inaccurate.
There -is- a complete listing available at MIT's museum of Apollo 11's program, and the following link has complete listing from Apollo 13.
It also contains good information on the Language itself.

There is no Hoax involved with it. Your concern that there was no development life cycle control are a bit unfounded, as SDLC's were just starting back then, leading to self documenting languages such as Cobol 64. That was about as far as SDLC's got in the 60's.
SDLC's only became common place by the late 80's. I'm sure NASA had something similar for quality control back then.
I fail to see how one page of a source listing constitutes a conspiracy, when there are complete listings available, as well as emulators that can still run that instruction set. (Again see that link I provided)
