+EnergiaMesh - Agent Collaboration Guide
+
+Architecture
+- Core primitives: LocalProblem, SharedVariables, PlanDelta, DualVariables, AuditLog
+- Graph-of-Contracts registry with versioned adapters
+- Lightweight starter adapters (DER controller, Weather station)
+- Transport: TLS-enabled (stubbed in MVP)
+- Adapter marketplace concept for pilots across vendors
+
+Tech Stack (MVP)
+- Python 3.9+
+- Core: energiamesh.core
+- Adapters: energiamesh.adapters
+- DSL sketch: energiamesh.dsl
+- Tests: pytest
+
+Testing & Commands
+- Run tests: `pytest` (in root, after `pip install -e .` or using build) via `test.sh`.
+- Build: `python3 -m build` in a clean environment.
+- Linting: not included in MVP to keep scope small; integrate later.
+
+Development Rules
+- Minimal, well-scoped changes. Avoid feature creep in this repository iteration.
+- Add tests for every new public API surface.
+- Use the src/ layout for packaging; keep imports stable.

-# energiamesh-federated-contract-driven-mi
+# EnergiaMesh (Prototype MVP)
 
-EnergiaMesh is a novel, open-source platform that enables cross-utility microgrid optimization across solar PV, wind, storage, and demand response using a federated, contract-driven data-exchange model. It introduces a lightweight, versioned contract
\ No newline at end of file
+EnergiaMesh is a prototype for federated, contract-driven microgrid optimization with on-device forecasting. This MVP focuses on the core data primitives and two starter adapters to bootstrap the CatOpt bridge in a minimal, testable form.
+
+What you can expect in this MVP:
+- Core primitives: LocalProblem, SharedVariables, PlanDelta, DualVariables, AuditLog
+- A simple Graph-of-Contracts registry for versioned adapters
+- Two starter adapters: DER controller and Weather station
+- A small DSL sketch placeholder for LocalProblem/SharedVariables/PlanDelta
+- Basic tests and packaging scaffolding to enable pytest and python build
+
+- Getting started
+- Install dependencies and run tests:
+  - bash test.sh
+- To explore the MVP, look under src/energiamesh/
+
+Packaging and publishing
+- This repository uses a Python packaging layout under src/ with pyproject.toml.
+- See READY_TO_PUBLISH when you are ready to publish the MVP as a package.
