### Description (declared)

A2A adapter for Kairos Signal data services. Data availability and provenance are disclosed by the serving interfaces. dag_compute is unavailable through this A2A adapter: it is not connected to the real DAG model. Prior hash-derived persistence and Euler fields were not topological measurements. No model inference is performed or charged. No predictive-performance or trading-return claim is made here.
