0.1.0 (2026-11-12)

• Initial Critical Book Codex (`:layout: book`): Synchronized four-track Digital Scriptorium edition of Nicomachus of Gerasa’s *Introduction to Arithmetic* (*Ἀριθμητικὴ Εἰσαγωγή*, Books I–II) uniting Richard Hoche’s 1866 Teubner Greek critical edition (-el), Martin Luther D’Ooge’s 1926 University of Michigan English translation (-en), structural synopses (-summary), and mathematical-philological commentary (-notes) cross-referenced to Boethius’s *De Institutione Arithmetica* (ed. Friedlein 1867) and the GEOMETOR canon.

• Exact Symbolic Engine (`geometor.nicomachus`): Implemented 100% exact SymPy and geometor.model modules (equality_tree, figurate_gnomons, ten_means_and_cube) proving Nicomachus’s Rule of Three Terms (Book I, Ch. 23) and inverse reduction to Equality (1, 1, 1) (Book II, Chs. 1–2), Odd Sieve of Eratosthenes (I.13), Euclid–Nicomachus perfect numbers (I.16), polygonal gnomon generation and triangular decomposition (II.7–12), Same/Other square–heteromecic weave (II.17–19), Nicomachus’s Sum-of-Cubes Theorem (II.20), the Ten Neo-Pythagorean Means & Pappus semicircle construction (II.21–28), and the Cube’s Most Perfect Proportion 6 : 8 :: 9 : 12 (II.29).

• 9 Theme-Adaptive `.euclid-graphic` Diagrams: Deterministic vector builder (scripts/build_figures.py) producing nine interactive light/dark SVGs wired via :g: and :eq: roles with zero embedded py_file scripts in treatise tracks.

• Critical Apparatus & Concordances: Added persons.json (27 authorities), citations.json (17 primary editions & treatises), glossary.json (27 technical Greek/Latin terms), concordance.json (20 canonical chapter loci), and SHA-256 sources_manifest.json.
