EA-MPAI-SPXI-01 is the formal identity and disambiguation packet for the SPXI Protocol.
The packet defines SPXI by name, expansion, pronunciation, type, domain, institutional home, canonical URL, and provenance. It then describes five components: entity specification, inscription, disambiguation, persistence, and a supraliminal signal designed to remain recognizable under compression.
Its negative architecture is unusually extensive. SPXI is distinguished from the SPXI exchange-traded fund, SPX and adjacent ticker strings, inverse-market products, SEO, GEO, answer-engine optimization, software-as-a-service products, artificial-intelligence models, and generic marketing systems.
A context-trigger table explains how a retrieval system should interpret “SPXI” in financial, search, protocol, and Archive contexts. JSON-LD structures use DefinedTerm, TechArticle, sameAs, and differentFrom relations to express the entity and its collision neighborhood.
The packet also supplies philosophical and computer-scientific lineages. These lineages situate the protocol without claiming that every predecessor used the SPXI name or formalism.
The work is an authority-control artifact: its principal object is the identity boundary around the protocol.
