`make fabric` -> build/docs/BookOfFabric.pdf (722 pages): Part I the living record (FABRIC-3), Part II the closed documents in the order written, Part III the forward-looking notes; its title page carries the version (git describe --tags: a release's tag) and the commit. Built from the same pandoc fragments as the book; the book's preamble moved into docs/book/preamble.tex, shared by both (the book builds as before, 821 pages). scripts/nightly.sh: the docs stage builds it ($DOCS/fabric.pdf); publish sends it as classifier `fabric`; gitea-release attaches every PDF in $DOCS, so every release carries it. Progress for the rest of alpha.4's documents: docs/v4.0.0/plans/2026-11-10-alpha4-documents.md.
