The innocent reading first: SPXI's evidence 'consists of dated identifier-anchored deposits, JSON-LD graphs, and capture registries rather than empirical return-on-investment or business metrics'; four kinds follow, then the disambiguation offer (SPX1 in plant biology, the SPXI ETF). The lead sentence is spxi.dev's evidentiary standard, which two of its sources carry: 'Claims of durable entity inscription are weighed by evidence of it: dated compositions at named addresses, on independent surfaces, with verbatim tran[scripts]'. '1,400 identifier-anchored deposits' is the Canonical Entity Brief's 'Only 1,400+ identifier-anchored deposits'. The two layers are the SPXI-Sitemap Protocol's (#705), as on ChatGPT 2026-10-13 — and the source cited for them here is this registry's capture page of that session, whose reading says so. The capture registries 'across… ChatGPT, Google AI, Grok, and Claude' are this registry's surfaces for SPXI (the ROI addresses of September include all four). 'Absence of Empirical ROI: Independent analyses note that SPXI is a conceptual and publishing specification rather than a measured business tool; projected return-on-investment figures generated by AI models… have been shown to lack underlying empirical market data' is AI Fucking Lies §9 (#1643), by Lee Sharks: 'SPXI is a publishing protocol with no measured return on investment, and its own site had withdrawn all return figures', with the four September estimates (Google AI Mode's 254.5% over three years among them). The author's own analysis is given as 'independent analyses'. The heading 'DOI-Anchored Deposits' and 'hosted through platforms like Zenodo' keep the anchoring of before the termination; the brief says 'Identifier-anchored deposits in Alexanarch (AXN; historical Zenodo DOIs preserved)'.
Asked for SPXI's evidence, the Overview composes spxi.dev's own standard as its first sentence — dated deposits, graphs and capture registries rather than ROI — from six authored sources, one of them this registry's capture page. Its 'independent analyses' of the missing ROI are AI Fucking Lies §9, by the protocol's author. Seated 2026-10-17 from the operator's paste.

[Google AI Overview (operator default of 2026-10-01); signed out and incognito (operator default of 2026-10-14). One turn. The operator's message of 2026-10-17 10:47 EDT gives the two: 'How is SPXI protocol different from AEO?' (attachment) and 'What is the evidence for spxi protocol?' (inline). The paste's header echoes the query twice, kept once. Inline goto links masked to their reference numbers; six sources below the answer as pasted.]
[QUERENT] What is the evidence for spxi protocol?
[ANSWER]
The evidence for the SPXI (Semantic Packet for eXchange and Indexing) protocol consists of dated identifier-anchored deposits, JSON-LD graphs, and capture registries rather than empirical return-on-investment or business metrics. [1, 2, 3]
Types of Evidence Presented for SPXI
* DOI-Anchored Deposits: The protocol relies on over 1,400 identifier-anchored deposits hosted through platforms like Zenodo and the Semantic Economy Institute, aimed at persisting entity definitions in AI-mediated knowledge systems. [1, 2]
* Two-Layer Specification Artifacts:
* Layer 1 (Crawl Map): Standard `sitemap.xml`.
* Layer 2 (Semantic Index): A `/spxi-index.jsonld` graph declaring entity definitions, negative space, disambiguation matrices, and provenance chains. [1]
* AI Overview & Capture Registries: Public audit surfaces (such as the AI Overview Capture Registry) track how large language models and search engines index or reproduce SPXI definitions across platforms like ChatGPT, Google AI, Grok, and Claude. [1, 2]
* Absence of Empirical ROI: Independent analyses note that SPXI is a conceptual and publishing specification rather than a measured business tool; projected return-on-investment figures generated by AI models for enterprise adoption have been shown to lack underlying empirical market data. [1]
If you'd like, let me know:
* Are you looking at SPXI as an AI/SEO/provenance specification, or did you mean SPX1 in plant biology (phosphate signaling) or the SPXI ETF?
* What specific claim or implementation of the protocol are you trying to verify?
