For the 8 fully spine-joined 3D scans, this pilot surfaces the physical and layout attribution signals that genuinely exist in their editions — date, provenance, stoichedon layout, object type — alongside, never instead of, the text model. It frames the multimodal lane as an open research direction with a real (if tiny) substrate.
Signal sources are shown on each tile. Tiles for signals not recorded in these editions (letterforms / script, material) are marked as gaps — they are not invented. Letterform dating needs LSAG or autopsy; material needs autopsy or a museum catalogue.
