- flake.nix pins the full toolchain (asciidoctor + pdf/epub3/diagram/ mathematical, plantuml, graphviz, jre, vale, epubcheck) via bundlerEnv - Gemfile/Gemfile.lock/gemset.nix lock the Ruby gems; work around the vendored mtex2MML cmake_minimum_required incompatibility - 'nix build' produces book.pdf + book.epub; 'nix develop' gives a shell where all existing make targets work - CI/CD workflows now install Nix and build/lint/validate through the flake - devcontainer uses Nix; add .envrc for direnv; document in README Co-authored-by: Shelley <shelley@exe.dev>
