Foundational Knowledge is a navigation page for a branch of the InfoPreserver library. Its job is to orient readers before they choose a more specific folder, and to show future contributors how this part of the collection is meant to grow.
In the current structure this branch sits under A4 Advanced Industry and Science. At A4, the subject requires professional training, advanced instruments, laboratories, formal quality control, or regulated practice.
The child folders currently organize work around Advanced Mathematics, Astronomy and Space Science, Atmospheric Science, Biology IV, Chemistry, Computing Theory, Electrical Theory, Geology and Geophysics, Materials Science, and Optics and Photonics. Some of those folders already contain documents, while others mark planned knowledge areas that still need sources, examples, and review.
Use this page as a map, not as the final technical manual. Start with the child folder closest to the immediate problem, then move sideways when the topic depends on another skill. A water, health, shelter, or workshop problem often crosses several branches.
For contributors, this branch should stay broad. Add detailed PDFs to the most specific leaf folder that fits. If a document applies to several topics, choose one primary home and preserve the cross-domain value through links, tags, or editorial notes.
This branch should contain orientation pages, practical manuals, teaching resources, standards, examples, and checklists that help readers move from general awareness to usable practice. It should not become a dumping ground for unrelated references just because a document mentions the topic in passing.
