If nobody else knows then they might not access, but I looked; at least some of the parts looks like interesting to me.

As well as others, depending on what you want to do; it is not quite as simple as "pure document oriented" (e.g. Gemini does have inputs (1x status code) and TLS as well, including authentication with client certificates).

It might also be made to be modular so that the file formats and other features can be added separately (including HTTP, HTML, Unicode, etc also would not be forcibly built-in, and the different protocols, file formats, character sets, and other features can be done by adding them on (which can be static or dynamic; static might allow some possible optimizations but would require recompiling and/or relinking it when you want to change it)).
