-# Open-EnergyMesh Offline-First MVP (Node.js)
+# Open-EnergyMesh MVP: Offline-First Distributed Microgrid Orchestration (0.2 protocol)
 
-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.
+This repository contains a minimal Open-EnergyMesh MVP focused on offline-first operation
+and displacement of vendor lock-in through a lightweight, pluggable architecture.
 
-What you get in this MVP:
-- Core data model for energy devices and components
-- 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
+- Core MVP: in-memory mesh with Inverter and Meter models and a tiny ADMM-lite integration path
+- 0.2 protocol scaffold: LocalProblem / SharedVariables / PlanDelta contracts (protocol.js)
+- Adapters: reference adapters for inverter and meter demonstrating plug-and-play interoperability
+- Solver: lightweight ADMM placeholder (solver_admm.js) to illustrate integration points
+- Delta-sync: MVP delta application via EnergyMesh.applyDeltaSync
 
-Usage
-- Install dependencies: npm install
-- Run tests: npm test
-- The repository exports Open-EnergyMesh primitives via src/mesh.js for extension.
+How to run tests
+- npm install
+- npm test
 
-Roadmap (high level)
-- Finalize a 0.2 core protocol and two starter adapters
-- 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
+Notes
+- This MVP intentionally keeps the surface small and extensible for future CatOpt-style composition and cross-vendor adapters.
+- See src/mesh.js for the current MVP data model and orchestration primitives.
 
-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.
+Marketing and publishing
+- When ready, publish readiness is signaled by creating a READY_TO_PUBLISH file at the repo root.
