0.1.0 (2026-11-12)

Initial scholarly edition and exact symbolic modeling release of geometor-cusa (De Docta Ignorantia [1440] & Scripta Mathematica [1445–1459]):

  • 4-Track Synchronized Book Codex (docsrc/de_docta_ignorantia/, :layout: book):

    • Unit I — Maximum & Learned Ignorance (Dedicatio, I.1–4, Epistola auctoris): Comparative proportion, the Absolute Maximum, polygon-in-circle exhaustion (I.3), and the coincidentia oppositorum.

    • Unit II — Mathematical Signs & Transsumption (I.11–12): Epistemic privilege of mathematical symbols and Cusa’s three-step method of transsumption (positio finita → transsumptio in infinitum → transitus in simplex maximum).

    • Unit III — Coincidence of Infinite Figures (I.13–15): Coincidence of the infinite circle and tangent arc with the straight line, collapse of the flattening triangle onto the base line, and unity of the infinite line, triangle, circle, and sphere (restoring two Rotta 1913 homeoteleuton omissions via Paris 1514 / Basel 1565 and Klibansky’s collation).

    • Unit IV — The Infinite Line & Infinite Sphere (I.16–23): The infinite line as essentia and mensura of all figures, participation of rectitude, Trinitarian complicatio/explicatio, and the infinite sphere (centrum cum circumferentia coincidit).

    • Unit V — Perspectival Cosmology & Mathematical Complementa (II.11–12 + De Geometricis Transmutationibus 1445, De Mathematicis Complementis 1453, De Mathematica Perfectione 1458, & Aurea Propositio in Mathematicis 1459): Decentered universe, relativity of motion, moving Earth, sesquiquarta rectification, and the fifth-order Snellius–Cusa law.

  • Exact Symbolic Geometry Engine & Interactive ``.euclid-graphic`` SVGs (src/geometor/cusa/):

    • Exact SymPy geometor.model constructions (auto_intersect=False, zero sp.Float) for coaxial tangent circle pencils and Möbius circle inversion (coincidentia_circle_line.py), Rational Trigonometry flattening triangles and Triple Quad Formula vanishing (coincidentia_triangle_line.py), regular polygon exhaustion, 1445 sesquiquarta rectification (\(\pi_{\text{Cusa}} = \frac{24\sqrt{21}}{35}\)), and 1458–1459 Aurea Propositio fifth-order Maclaurin series residual (\(\theta^5 / 180\)) (polygon_exhaustion_and_complementa.py).

    • Nine dark/light theme-adaptive .euclid-graphic SVGs in docsrc/_static/figures/ and three runnable symbolic demonstration scripts in demos/.

  • Cross-Corpus Concordance & Scholarly Apparatus:

    • Comprehensive concordance linking Cusa’s chapters and theorems to plato, aristotle, proclus, aquinas, hoenen, pacioli, durer, kepler, archimedes, casey, wildberger, and klein, paired with SHA-256 sources_manifest.json, glossary.json, persons.json, and citations.json.
