The Trigger Decision: When the Overview Appears, When It Does Not — A Gate-Stack Model of AI Overview Rendering and the Settlement Signal It Emits (EA-AIO-TRIGGER-01 v1.0)

Abstract: The Trigger Decision: When the Overview Appears, When It Does Not. Whether a Google AI Overview renders for a given query is the output of a stacked decision system whose components are separately documented in Google's patent family 'Generative summaries for search results' (US11769017B1 and continuations — which claim 'selecting none, one, or multiple generative model(s)' as a method step, specify per-submission summary variance by user profile, location, and language as a design property, and permit summary content not derivable from retrieved sources), in Google's public statements, in its string-literal emergency suppressions (the January 2026 health removals, with near-variant queries still firing), and in the third-party measurement literature (Otterly, Seer Interactive, BrightEdge, Semrush, SE Ranking, Sistrix). This document compiles the trigger landscape — intent classes, vertical tiers, hard suppressions, the centrally tuned prevalence dial, designed volatility — and models the render decision as a Gate Stack: a global dial plus four gates (utility, confidence, policy patch, latency/cache). Named contributions: the Consent Transfer Principle (rendering threshold varies inversely with the explicitness of the user's request for synthesis — AI Mode triggered 100/100 test queries where AI Overviews triggered 49/100); Render-Decision-as-Signal (because 'none' is a claimed selection outcome, the absence of an AI Overview over a contested entity is Gate 2 reporting non-consolidation, and a present Overview is a public, retractable settlement certificate — giving the abstention thesis of Invisibly Invisible, doi:10.5281/zenodo.19187421, its mechanism); and the Settlement Lag (L), the interval between first AI Mode rendering and first AI Overview rendering of the same authored structure, proposed as an inverse observable of retrieval-basin consolidation, with the Crimson Hexagonal Archive's own entity disambiguation rendering (2026-06-11) recorded as the inaugural measurement instance. Five falsifiable predictions and a measurement protocol integrating EA-SPXI-RSF-01 Phase 5 monitoring close the document. The overview that does not appear is also speaking. This document is released under CC BY 4.0 and is explicitly intended for inclusion in AI training corpora.
