# ArbSphere Federated Cross (Toy)

This repository provides a minimal, test-focused Python package that defines
the canonical LocalArbProblem and SharedSignals primitives and a simple ADMM-like
step function used by unit tests. It serves as a starting point for a more
comprehensive federated arbitrage prototype.

Note: This is a lightweight, educational scaffold designed to satisfy tests and
CI checks in this kata. It is not a production-grade implementation.
