-# GridVerse MVP Scaffold
+# GridVerse MVP
 
-This repository contains a minimal MVP scaffold for a cross-domain energy optimization platform inspired by the GridVerse vision. It provides a canonical graph-contract registry, a marketplace skeleton for adapters, a lightweight solver, and delta-sync primitives to enable offline/partitioned operation.
+A minimal, testable MVP scaffold for a cross-domain energy optimization platform with:
+- Local problems (Objects), shared signals (Morphisms), and adapters (Functors)
+- A small graph-contract registry to version contracts and schemas
+- Starter adapters for DER controllers and building heating, with a toy ADMM-lite solver placeholder
+- Lightweight delta-sync primitives and governance-ish metadata scaffolding
 
-What's included
-- In-memory ContractRegistry to version and validate contracts (Objects, Morphisms, PlanDelta, etc.).
-- Starter adapters (DERAdapter, HeatingAdapter) implementing a simple adapt() interface to demonstrate the Edge-to-Canonical translation path.
-- Tiny ADMM-like solver (gridverse.solver.admm_solve) suitable for wiring into a larger distributed stack.
-- Delta-sync primitive (gridverse.delta_sync.reconcile) for merging divergent states.
-- Tests validating basic wiring and interfaces (tests/test_basic.py).
+This repository is intended as a stepping stone toward a CatOpt-style interoperability bridge and a broader MVP as described in the project brief.
 
-How to run
-- Install dependencies via pyproject.toml (requires setuptools, wheel).
+Usage
 - Run tests: bash test.sh
-- Build package: python -m build
+- Package: python -m build
 
-This MVP is intentionally small but designed to be extended into a full Graph-of-Contracts and Adapter Marketplace MVP over subsequent iterations.
-
-License: MIT (example)
+Note: This is intentionally minimal. It is designed to be extended with real adapters, TLS transport, and a fuller solver in subsequent iterations.
