SignalVault Verifiable Privacy-Preserving Signal Repository (MVP)

This project implements a portable, graph-backed signal store focused on verifiable provenance, offline replay, and privacy-preserving sharing of market signals across venues. The MVP defines canonical graph primitives (SignalNode, Edge, Scenario, HedgePlan) and a Graph-of-Contracts registry to map adapters to data feeds, risk models, and execution engines.

What you get in this MVP:

• Core graph primitives and a tiny in-memory registry
• Deterministic replay engine for applying deltas and reconstructing signal state
• Privacy primitives placeholders (secure aggregation, DP budgets)
• Toy adapters for a price feed and a simulated venue
• Lightweight tests validating schema and replay behavior

How to run locally:

• Ensure Python 3.11+ is installed
• Run tests via: ./test.sh
• Build package via: python3 -m build (as part of test.sh)

Publishing notes:

• Python package name: signalvault_verifiable_privacy_preservin
• Exposes a small public API surface for MVP exploration and integration tests

This repo intentionally keeps scope minimal and testable to facilitate 1-feature-per-sprint iteration.
