ArbSphere Prose (Prototype)

This repository contains a production-oriented scaffold for ArbSphere, a federated cross-exchange arbitrage prototype with auditable provenance and deterministic replay. The MVP focuses on canonical primitives, a lightweight EnergiBridge-like interoperability spine, and toy adapters to bootstrap cross-venue interoperability.

What’s included

• Python package arbsphere with primitives: LocalArbProblem, SharedSignals, PlanDelta, DualVariables, PrivacyBudget, AuditLog, TimeRounds, GoCRegistry
• EnergiBridge-style IR bridge: arbsphere/energi_bridge.py
• Toy adapters: arbsphere/adapters/data_feed_adapter.py and arbsphere/adapters/broker_gateway_adapter.py
• Lightweight tests for primitives and IR round-trips: tests/test_primitives.py
• Test runner: test.sh (pytest + python -m build)
• Packaging: pyproject.toml

How to run

• Install dependencies and run tests
  • bash test.sh
• Inspect the MVP adapters and primitives under arbsphere/

Notes

• This is a focused MVP: extend with additional contracts, privacy budgets, cryptographic attestations, and governance logging as you iterate.
• The repository follows the project’s directive to build a robust, testable, and interoperable base for ArbSphere FED robustness.
