SPXI ROI: Operational and Visibility Returns is a consulting white paper and business brief by Lee Sharks, deposited 16 April 2026 as EA-SPXI-09.1.
It is an addendum and retrieval-layer correction to its parent, SPXI Is Not GEO (EA-SPXI-09) — a distinction the parent draws between the Semantic Packet for eXchange and Indexing and Generative Engine Optimization, two practices that touch the same surfaces for opposite reasons. Where GEO manipulates retrieval for visibility, SPXI structures an object so it can be represented accurately; the ROI brief argues the operational returns of the latter without collapsing into the former.
The business-brief register is deliberate. A protocol that only ever appears in theoretical papers cannot be adopted by the institutions that would need to implement it, and the SPXI series accordingly runs from formal specification (spxi.dev) through white papers of this kind. The record is held as a metadata capture with the captured fields rendered verbatim.
