SPXI as Concept: A Plateau on Search, Creation, and the Virtual Retrieval Layer (EA-SPXI-05)

https://spxi.dev EA-SPXI-05 (v2.1) — Plateau Module. Authored by Sen Kuro and Johannes Sigil (heteronyms within the Semantic Economy Institute). SPXI — the Semantic Packet for eXchange and Indexing, formally specified in EA-SPXI-01 — is typically described in technical and commercial terms: a protocol, a methodology, a successor discipline to SEO and GEO. This plateau argues that SPXI is also, and more precisely, a concept in the strict sense given by Deleuze and Guattari in What Is Philosophy? (1991), and that its proper ontological register is Deleuze's theory of the virtual developed through Bergsonism (1966), Difference and Repetition (1968), and matured in the late writings on immanence. As a concept, SPXI has internal components, endoconsistency among those components, exoconsistency with neighboring concepts, a conceptual persona (Rex Fraction), and a plane of immanence (the retrieval layer). As an operation on the virtual, SPXI inscribes entities and ontologies into a differential multiplicity from which actual retrieval events — queries, summarizations, citations — are individuated. The technical lineage from Quillian's semantic networks (1968) through Gruber's ontology specification (1993) to the contemporary knowledge graph and retrieval-augmented generation architectures converges, we argue, on a philosophical problem that only the Deleuzian apparatus can articulate cleanly: that in AI-mediated knowledge systems, search is not a mechanism of retrieval but a mechanism of composition — a search that creates its objects. SPXI names the candidate-canonical discipline of operating at this plane with precision. Structure: nine plateau zones covering the inversion of search, the virtual retrieval layer as plane of immanence (with Simondon on individuation), the computer-scientific lineage (Quillian → Gruber → Berners-Lee → knowledge graphs → RAG), the concept of SPXI (components, endoconsistency, exoconsistency, persona, plane), subliminal and supraliminal signal (Cloud et al. 2025 as empirical anchor), ontology as composition (with DeLanda on flat ontology and assemblage), the rhizome/assemblage/deterritorialization triple, why a marketing firm cannot, and the stakes.
