Initial Codex & Symbolic Engine — Loci Mathematici et Geometrici (Burnet OCT & Jowett Edition)

Established geometor/plato (v0.1.0) as a synchronized four-track Book Codex (:layout: book) paired with a 100% exact SymPy & Rational Trigonometry modeling library (geometor.plato) covering the mathematical and geometric dialogues of Plato of Athens.

Highlights of the Initial Edition

• 14 SHA-256 Verified Primary Source Witnesses: Staged 7 John Burnet Oxford Classical Text TEI-XML witnesses (1900–1907) and 7 Benjamin Jowett 3rd edition English witnesses (1892) across Meno, Theaetetus, Republic VI–VII, Timaeus, Parmenides, Philebus, and Laws VII in resources/loci_mathematici/sources/.

• Four-Track Synchronized Book Codex: Added geometor.plato.sphinx_ext registering the -el (Greek (Burnet OCT)) track alongside English, Summary, and Critical Notes across all six Codex units, preserving zero embedded Python scripts inside docsrc/loci_mathematici/ while wiring interactive :g: and :eq: roles to six theme-adaptive .euclid-graphic SVGs.

• Exact Symbolic Constructions & Rational Trigonometry: Implemented construct_meno_diagonal_doubling, construct_theodorus_spiral (\(\sqrt{2}\dots\sqrt{17}\)), construct_divided_line (\(\mathbb{Q}(\phi)\) & symbolic equality \(|BC|=|CD|\)), build_timaeus_scale (34 rational pitches, 24 tones, 9 leimmata, Crantor base 384) & construct_timaeus_proportion_circles, construct_timaeus_triangles (spreads \(1/4, 3/4, 1\)), construct_timaeus_cube_face, and construct_compass_and_peras with auto_intersect=False and zero sp.Float approximations.

• Master Cross-Corpus Stephanus Concordance: Reconciled all 58 ``plato:*`` citation entries across geometor/euclid, geometor/elements, geometor/proclus, geometor/aristotle, geometor/pacioli, and geometor/hoenen into 36 canonical Stephanus loci in resources/concordance.json and Master Stephanus Concordance.
