-# Open-EnergyMesh Offline-First Microgrid Platform (MVP)
+# Open-EnergyMesh Offline-First MVP (Node.js)
 
-This repository provides a minimal in-memory MVP for offline-first distributed microgrid orchestration.
+This repository provides a minimal Open-EnergyMesh scaffold focused on an offline-first, distributed microgrid orchestration flow. It implements a small in-memory data model (Device, Inverter, Meter, DER, PriceQuote, Forecast) and a lightweight EnergyMesh orchestrator with a simple energy-flow calculation. It also includes a placeholder ADMM-like solver to demonstrate how a compositional optimization layer can be integrated on top of the runtime.
-Core concepts:
+
-- EnergyMesh orchestrates devices such as Inverters and Meters and computes energy flow.
+What you get in this MVP:
-- ADMM-like scaffold is included as a forward-looking compositional optimization hook.
+- Core data model for energy devices and components
-- Data contracts and adapters allow plugging in additional devices (DERs, storage, etc.).
+- Basic energy-flow computation: generation minus consumption
+- A lightweight ADMM-lite adapter surface (solver_admm.js)
+- Delta-sync helper and an API surface to apply per-device deltas
+- Simple tests that exercise computeFlow, delta-sync, and ADMM integration
+- Lightweight, well-scoped scaffolding suitable for MVP testing and iteration
 
 Usage
 - Install dependencies: npm install
 - Run tests: npm test
+- The repository exports Open-EnergyMesh primitives via src/mesh.js for extension.
 
-Notes
+Roadmap (high level)
-- This MVP emphasizes offline resilience and a clean path toward modular optimization layers.
+- Finalize a 0.2 core protocol and two starter adapters
-- See src/mesh.js and src/solver_admm.js for the basic in-memory implementation and the ADMM scaffold.
+- Implement an ADMM-lite local solver with offline/partially-connected rounds (delta-sync)
+- Add privacy-preserving options and governance hooks
+- Provide a small reference adapter SDK and HIL testbed
 
-License: MIT
+This project is designed to be extended incrementally. See AGENTS.md for architectural rules and contribution guidelines.
+
+Commit messages follow a concise rationale-focused style suitable for collaborative reviews.
