Public, then bigger
The day opened with version 2 going to public staging, and the monument dossiers gaining one measurement infographic each; the Parthenon’s measured 4:9 stylobate relationship with its 0.029% residual, the Pantheon’s 43.30-metre diameter-height equality drawn as an inscribed sphere, and Stonehenge’s solstitial axis kept deliberately separate from its contested megalithic-yard reading.
Five converters
Then the toolset grew: Liquid and Area joined Length in the morning; Weight and Time followed. Alcohol measures were grouped inside the Liquid converter rather than given their own tool; casks, servings, and ancient wine-trade measures all carry their commodity, jurisdiction, and period so nothing false-equates. Standard drinks and proof gallons were excluded on principle, because both depend on alcohol strength as well as volume, and the converter stays dimensionally honest. A correction landed the same way: the unsupported 48-litre Egyptian khar was removed, and the Middle Kingdom 96-litre form was distinguished from the New Kingdom 76.8-litre form.
The register keeps up
Every expansion was reconciled the same day: the Units catalogue rebuilt (98 units, then 183 by evening; 7,541 ordered pairs, worst round-trip error 2.22e-16), the public Source Register rebuilt directly from the deployed matrices, the Methodology rewritten to cover all the dimensions, the footer simplified sitewide, and the Treasure calculator added with its own evidence-aware composition engine after 1,631 searchable PDF pages of newly supplied sources were audited. Validation passed at every step with zero errors and zero warnings.
