Inaugural Digital Scriptorium Codex & Visual Pseudocode Engine (v0.1.0)

Launched geometor/byrne (v0.1.0), uniting Oliver Byrne's 1847 Chiswick Press First Six Books of the Elements of Euclid with GEOMETOR’s exact symbolic geometry engine:

• Archival Multimodal Calibration: Inspected 26 high-resolution pages directly from the 1847 William Pickering / Charles Whittingham print (Internet Archive firstsixbooksofe00eucl, Thomas Fisher Rare Book Library scan) to verify Byrne’s Simson axiom numbering, custom operators (⊏, ⊐, bisected semicircle for two right angles), Book V magnitude icons, and authentic 4-color plate assignments—including documenting the famous 1847 Title Page I.47 color-plate transposition relative to pp. 48–49.

• Self-Contained Inline Glyph Roles (``geometor.byrne.sphinx_ext``): Implemented :byrne-line:, :byrne-angle:, :byrne-tri:, :byrne-sq:, :byrne-rect:, :byrne-arc:, :byrne-circle:, :byrne-mag:, and :byrne-op: with theme-adaptive Chiswick Press CSS variables and bidirectional SVG hover/click highlighting without modifying photon-platform/publish.

• Pointer-Free Visual Pseudocode Grammar (``geometor.byrne.pseudocode``): Modeled Byrne’s notation as a pass-by-value geometric token DSL across I.1, I.5, I.47, II.11, IV.10, IV.11, and V.16, quantifying 80–92.9% verbal compression, zero alphabetic pointer dereferencing, stroke-modulation register expansion, and congruence-twin symmetry.

• 17 Exact Symbolic ``.euclid-graphic`` Plates (``geometor.byrne.constructions`` & ``render``): Built 100% exact geometor.model.Model constructions (zero sp.Float) over $\mathbb{Q}$, $\mathbb{Q}(\sqrt{3})$, $\mathbb{Q}(\phi)$, and pentagonal radical towers with verified Rational Trigonometry proof checks.
