SPXI.dev was a protocol-specification landing page for SPXI, the Semantic Packet for eXchange & Indexing.
The surviving metadata presents SPXI as a method for durable entity inscription across retrieval and composition systems. Its contrastive formula is: SEO optimizes pages, GEO optimizes content, and SPXI inscribes entities.
The page reportedly supplied the protocol’s canonical name, pronunciation, definition, architecture, disambiguation, and relation to adjacent optimization practices. Its function was not only promotional. It served as a machine-readable identity surface intended to keep “SPXI” from collapsing into stock tickers, search terminology, or unrelated acronyms.
The original landing-page bytes are not seated in this record. A later, fuller capture of the /, /what-is-spxi, and /disambiguation surfaces exists at deposit #1234 and should be used for the restored website manifestation.
Record #974 remains useful as the historical metadata witness for the earlier landing-page deposit and its dead DOI.
