02 — What you getA plugin, not a platform
The engine
Signed multi-source quotes → integer median + outlier rejection + freshness, fail-closed. One source manipulated 10× cannot move the price.
The delivery
A plugin, not a platform — drop it into your own stack. You receive a self-hostable module plus a hosted JSON API and its OpenAPI spec, so you compose Beacon into your product instead of rebuilding this layer.

A manipulated source should move nothing.
