Emboss v0.2.0

Deterministic, PDF/UA-tagged, veraPDF-conformant PDF generation, built for LLM-driven document pipelines.

Highlights

Enterprise foundations

• Real veraPDF conformance run in CI (emboss verify --conformance), not a simulated check
• Self-describing PDFs: render(embed_spec=True) attaches the document's own spec, layout map, and a Markdown twin; Document.from_pdf() recovers from either
• Stable node ids and a queryable layout map on every render
• Document diff and redline: diff_documents() / render_redline() / emboss diff
• Reproducibility manifest and emboss reproduce
• Redaction by construction (content never enters the stream) and DocMDP certification signing
• BrandKit: one versioned brand object propagates across every document
• emboss strip for external distribution

Document structure

• CoverPage, Abstract, Authors, PullQuote, StatTiles, visible TableOfContents, Appendix, Index, Glossary
• Executive decks (SlideDeck): nine layouts, four themes, fit-to-slide validation
• Diagram element: node/edge graphs with automatic layered-DAG layout
• Equation numbering, @eq/\eqref references, real math alphabets, MathML input
• Landscape and mixed page geometry within one document

Typography and rendering

• Full SVG subset: arcs, gradients, transforms, clipping, real opacity
• Hardened charts: zero baseline, no truncation, pattern fills, fact-verified captions
• CMYK and PDF/A archival output
• Bundled OFL font set (Source Serif/Sans/Code, Emboss Math)

LLM integration

• Provider-native structured outputs, a validation repair loop, genre exemplars
• Document.from_llm() auto-routing, YAML front matter in Markdown input

Install: pip install emboss-pdf
