I’m unclear what you mean when you say “codify the knowledge”. Do you mean like start a list of important things needed (more than just skills). Like “how to purify water”, “how to spin thread using a spinning wheel AND detailed plans for building a spinning wheel”, same for making cloth, etc, etc?
If this is correct then I would like to see (or help make) a list of these items. Start with a list of the most important things (gadgets) needed. Start with the top 100 (or 200 or 300 or however many there might be). Then document knowledge sources for each. In the case of “how to purify water” I would start here https://en.wikipedia.org/wiki/Water_filter print or save this page to a PDF, go to every important link on that page, like https://en.wikipedia.org/wiki/Filtration and https://en.wikipedia.org/wiki/Water_purification and https://en.wikipedia.org/wiki/Portable_water_purification and print or save to PDF all those pages. Then go to all the pages under “See Also” and save, then try to find every article or book under “References”. From this you can figure out the real world things needed and start searching for detail construction drawings (most difficult to find).
I have spent much of this year finding these kinds of pages, building an outline thereof, and the books referenced there, but nothing on determining gadgets and the construction drawings of the gadgets – of the large subject of engineering.
