mission

geometor.lemoine establishes a rigorous, folio-verified Digital Scriptorium edition of Émile Lemoine’s Géométrographie, ou Art des constructions géométriques (1888 / 1892 / 1902), uniting quantitative construction complexity with minimal-instrument constructibility across the GEOMETOR ecosystem.

Core Objectives

1. Multimodal Archival Fidelity: Ground every operation symbol, coefficient (\(S, E\)), and problem locus in direct 300 DPI page-by-page scan inspection of Lemoine’s French treatise, Lorenzo Mascheroni’s La Geometria del Compasso (1797 / Fazzari 1901 Palermo edition), and Jakob Steiner’s Die geometrischen Constructionen (1833 / Ostwald Nr. 60, 1895), backed by SHA-256 verified primary witnesses in resources/geometrographie/sources_manifest.json.

2. Synchronized 4-Track Book Codex: Present Géométrographie in photon-platform/publish :layout: book format with runtime support for synchronized English, French (1902), Summary, and Commentary/Notes tracks alongside nine exact symbolic .euclid-graphic SVG plates—maintaining strict separation between historical editions and executable code.

3. Dual Minimal-Instrument Concordance: Cross-map Euclidean ruler-and-compass benchmarks (, , ) simultaneously onto Mascheroni’s compass-only subspace (\(l_1 = l_2 = 0\)) and Poncelet–Steiner’s fixed-circle straightedge subspace (\(m_1 = m_2 = m_3 = 0\)), illuminating why inversive transformations favor the compass while projective/harmonic correlations favor the straightedge.
