The three badges answer three different questions, and the second and third exist because the first one has lied before. The workflow badge says the last run on main went green. The site badge says the URL answers. The “site built” badge reads build-info.json off the live site, so it says which build is actually being served: on 2026-08-06 the build job was green while deploy-pages timed out, and the site served the previous commit for hours with nothing showing it.

Course materials for Systems and Toolchains for AI Engineers, Fall 2026.

The rendered site is public: https://kitchingroup.cheme.cmu.edu/f26-06763/

Anything listed in the toc: of _toc.yml is published to that site. Anything not listed stays private, which is why course/modules/ (instructor planning and teaching notes) is deliberately excluded.

One directory per session, l01 through l22, matching the L-numbers in course/schedule.md. lectures/l01/ is the worked reference for both formats.

pip install "jupyter-book<2"  # 1.x is required, see CLAUDE.md section 8
jupyter-book build .          # full book into _build/html

npx @marp-team/marp-cli lectures/l01/slides.md -o /tmp/l01.html

Pushing to main builds the book, renders every slide deck, and deploys to GitHub Pages via .github/workflows/book.yml.

Lecture notes are “textbook” documents/chapters meant to be read outside class. Slides are for presentation of the content during lectures. They are separate artifacts with separate jobs, both derived from the corresponding lecture block in course/modules/wkNN.md. The full orchestraton is in CLAUDE.md.
