Ética — a multi-agent book production pipeline

An automated, agent-orchestrated pipeline that turns a public-domain source text (the Elwes translation of Spinoza's Ethics) into a modern, typeset book — print-ready PDF, EPUB3/Kindle, generative cover art, and a multi-language build — with quality gates between stages.

This repo is the engineering, not the book. The full adapted prose is a separate commercial edition (on Kindle); here you get the pipeline and a Part I sample so the system is inspectable end to end.

What it does

source text ──▶ structure ──▶ typeset ──▶ art ──▶ package ──▶ gate
 (Gutenberg)     parts/CSS      Paged.js    SVG      EPUB/PDF   _gates.py

• Typesetting — build_pdf.py + render.py drive Paged.js over book.css to produce a print-ready PDF (running heads, page breaks, apparatus).
• EPUB/Kindle — build_epub.py, epub_kindle.py, build_fxl_epub.py package validated EPUB3 and Kindle outputs from the same source.
• Generative art — gen_art.py, gen_cover.py, gen_covers.py, localize_svgs.py produce covers and figures, sized to the current page count.
• Multi-language — build_lang.py orchestrates per-language builds from one source; make_kdp_guides.py emits the KDP metadata guides per edition.
• Quality gates — _gates.py blocks a stage from shipping if the previous stage's output fails its checks (the "agent that says no").
• Web sample — build_sample_web.py / build_site.py render the public sample (Preface + Part I).

Run the sample

python src/build_sample_web.py   # renders the Part I web sample
python src/build_pdf.py          # print-ready PDF of the included sample

What's included vs. not

Included: the full pipeline (src/*.py), templates/CSS, generative art (assets/), the public-domain source (fontes/), and a Part I sample (src/parts/preface.html, parte-1.html, plus glossary/closing).

Not included (by design): the complete adapted prose (Parts II–V), the translated editions, and the compiled PDF/EPUB — those are the paid product. .gitignore hard-denies them; git ls-files was verified clean before the first commit.
