ArbSphere - Federated Cross-Exchange Equity Arbitrage Primitives (Toy MVP)

Overview

• Provides a minimal, test-driven prototype of canonical ArbSphere primitives:
  • LocalArbProblem, SharedSignals, PlanDelta, DualVariables, AuditLog, PrivacyBudget
• A lightweight EnergiBridge-like IR mapping (arbsphere.ir.map_to_ir)
• A tiny ADMM-style coordinator (arbsphere.coordinator.admm_lite_step)
• A Graph-of-Contracts registry scaffold (arbsphere.go_registry.GoCRegistry)
• Toy adapters (price feed, broker) to bootstrap interoperability

How to run tests

• Ensure Python 3.8+ is available
• Run: pytest -q
• (Optional) Run packaging check: python -m build

Notes

• This is a production-oriented scaffold focused on deterministic replay, auditable provenance, and interoperability. It is not a complete trading system.
