I'm not sure what you're referring to since the files T.C. Lee posted on that geocities site are the only design documents he (or anyone else) ever released, and those are preserved in the SFFiles.zip found at the oocities mirror linked from the github there. That zip contained only a partial dump of some source code, while that sonic.net page contains a more complete copy (but lacks any kind of design documents whatsoever). Was there something else you were referring to?

I seem to recall browsing what appeared to be the complete source back in the day. I put in a bit of an effort to get it compiling, but it was only released as poorly scanned printouts of the source code and OCR wasn't so good then so the project was bigger than I hoped.

That would be the source code posted to that sonic.net site. It was a mix of raw dumps of FORTH blocks and printouts converted to PDFs. It wasn't the full source code, and there weren't any design documents in there.

You can see on archive.org where it captured directory info for files which were not stored:

https://web.archive.org/web/20031218202130/http://www.sonic....

When you navigate those directory archives many of the files are missing. E.g.

https://web.archive.org/web/20030529230704/http://www.sonic....

Some design documents ARE there, e.g. "Specification of 3d display for starquest" : https://web.archive.org/web/20030719111039if_/http://www.son...

Well....... shit. I'd been in there previously and never noticed that. Disregard.
