A single-domain feed cannot see a compound event: a grid operator's data does not know about the storm, and a market feed does not know that two agencies disagree about an earthquake. pronto.stream computes 35 fusion products across diverse physical, environmental, macro, and financial streams arriving on one synchronized clock.
Each product implements a published, externally validated index or model, and explicitly cites the correlation IDs of the underlying signals it was computed from. A product with missing live inputs returns nothing rather than interpolating or inventing a value.
Every fusion output emits an explicit Attribution and Scope. Published indicates a faithful implementation of an external, citable index (e.g. NOAA, EPA, Estrella-Mishkin). Composed indicates authoritative published inputs combined by a transparent decision rule disclosed in the documentation. The scope states whether an answer applies to a single sensor (point), an event (event), a market (regional), or the entire world (global).
