 - Minimal EnergiBridge mapping layer to a canonical Graph-of-Contracts IR
 - Packaging scaffolding for a robust build and distribution (pyproject.toml)
 
+Enhanced Overview
+- Deterministic offline replay: store and replay deltas with provenance for auditability.
+- Privacy-first signals: per-signal budgets and secure aggregation; raw data stays local.
+- Lite Graph-of-Contracts registry to map adapters to data contracts and engines.
+- End-to-end MVP: 2 starter adapters (FIX/WebSocket price feed and simulated venue) over TLS.
+- EnergiBridge-like interoperability layer to enable cross-domain reuse and conformance testing.
+
+MVP Plan (8–12 weeks)
+- Phase 0: Protocol skeleton + 2 starter adapters over TLS; lightweight ADMM-lite local solver; end-to-end delta-sync with deterministic replay.
+- Phase 1: Governance ledger and identity management; secure aggregation defaults for SharedVariables.
+- Phase 2: Cross-venue demo with a toy two-asset setup; EnergiBridge SDK integration and toy adapters.
+- Phase 3: SDKs, conformance tests, and lightweight audit dashboards.
