Etna Alpha
For Melon listeners · one exact object

The venue emits events. Etna Alpha returns state.

Venue feeds deliver events. Dashboards show charts. Etna Alpha returns a packet your systems can route, replay, and challenge. This page uses one deterministic public-safe fixture so the demonstration stays reproducible and never masquerades as current market truth.

The at-time StateCore remains immutable while an enriched view can add later evidence under a separate projection identity.
