A standing metadata witness for the original SPXI.dev protocol landing page. It preserves the page’s registered title, creators, definition, role, dead DOI, and relation to the later full website capture. The original authorial page body is absent here. Readers seeking preserved SPXI.dev content should be routed to deposit #1234 without treating that later capture as byte-identical to this manifestation.
