Description: WHAT IS SPXI PROTOCOL? ON CHATGPT: signed out, ChatGPT gives the Semantic Packet for eXchange & Indexing 'that has appeared in 2026', described by the Semantic Economy Institute, then xSPI and the SPXI ETF as easy confusions — with an Alexanarch chip beside them — and closes asking whether SPXI was met in 'AI/SEO marketing, cryptocurrency or investing, or computer hardware'.
Reading: The innocent reading first: 'SPXI protocol can refer to different things depending on the context'; one meaning, 'that has appeared in 2026', is the Semantic Packet for eXchange & Indexing, a framework for helping AI systems identify entities, described by the Semantic Economy Institute; the acronym is 'easy to confuse with' xSPI and the SPXI ETF; it closes asking 'Where did you encounter SPXI? Was it in AI/SEO marketing, cryptocurrency or investing, or computer hardware?'. The protocol is resolved in the first sentence, with its expansion and its institution. The query's 'protocol' is treated as compatible with three meanings; the published context rule makes it a trigger for the Protocol (#63 §5.1; spxi.dev/disambiguation). The xSPI/ETF sentence carries an Alexanarch chip: this registry's record of 'what is spxi protocol?' on Google AI Overview (2 and 13 October) holds the Overview's own xSPI and IPX/SPX alternatives, and is a plausible source; the chip's target is not in the paste. 'Cryptocurrency' appears in the closing question and nowhere in the sources.
Analysis: Asked 'What is spxi protocol?', signed-out ChatGPT resolves the Semantic Packet for eXchange & Indexing and its institution in the first sentence, then offers xSPI and the ETF as confusions — beside an Alexanarch chip — and asks which context was meant. Seated 2026-10-18 from the operator's paste.
Match: BROAD MATCH — 'WHAT IS SPXI PROTOCOL?' — THE PROTOCOL FIRST, THEN xSPI AND THE ETF, THEN 'WHERE DID YOU ENCOUNTER SPXI?'
PER: 0.5 — Retained: the institution (Semantic Economy Institute), the expansion, visible sources. Lost: the author (Rex Fraction) and identifiers.
