AION — Adaptive Incremental Operational Network

A Rust-based incremental computation engine for AI agents.

TL;DR

AION provides a reactive, incremental computation substrate that enables AI agents to maintain consistent world models with minimal recomputation. Built on Salsa for query-level incrementality and Differential Dataflow for relational delta processing.
