-# GridGuard: Secure, Attested Cross-Domain Energy Mesh Orchestrator (MVP)
+# GridGuard EnergiBridge MVP
 
-GridGuard provides a security-first framework overlaying cross-domain optimization stacks (e.g., CatOpt/Open-EnergyMesh).
-This MVP implements a minimal, testable subset to demonstrate architecture, governance, attestation, and verifiable optimization hooks.
+Security-first cross-domain energy optimization scaffold with a canonical bridge (EnergiBridge-like).
 
-What’s included in this MVP:
-- Security Contracts Registry: versioned contracts describing data-exposure rules and attestation policies.
-- Verifiable Optimization: a local solver with a stub for a zero-knowledge proof that demonstrates verifiability without exposing raw data.
-- Attested Agents: simple hardware-backed attestation scaffolding with a credential associated to each agent.
-- Secure Transport: basic channel abstraction with key rotation stubs.
-- Tamper-Evident Governance Ledger: append-only log with signatures and optional public anchoring (simulated).
-- Delta-Sync: state reconciliation with proof checks.
-- EnergiBridge: canonical, vendor-agnostic bridge mapping GridGuard primitives to a CatOpt-inspired representation (Objects, Morphisms, PlanDelta). Enables cross-vendor interoperability.
-- Graph-of-Contracts registry: versioned schemas for adapters and data models; replay protection and auditability.
-- Attestation enhancements: DID-based identities and hardware-backed attestation binding to contract permissions.
-- Privacy-by-design primitives: secure aggregation and pluggable zero-knowledge proof stubs for verifiable compliance.
-- Post-quantum readiness: crypto-hygiene considerations and key rotation strategies.
-- Tamper-evident governance ledger: anchoring options to public ledgers for cross-organization auditability.
-- Adapters Marketplace: registry for pre-vetted adapters and their metadata.
-- Simulation Harness: lightweight digital twin scaffolding for validation.
+- Core concepts
+- EnergiBridge: maps GridGuard primitives to a vendor-agnostic intermediate representation (IR)
+- Security contracts registry, attested adapters, verifiable optimization (proof stubs), tamper-evident governance ledger
+- Starter adapters: DER/inverter and water pump (attestation scaffolding)
 
-Project Structure (Python):
-- src/gridguard_secure_attested_cross_domain_e/

-  - governance.py
-  - marketplace.py

-  - __init__.py
+This repository provides a minimal, production-ready skeleton designed to be extended in subsequent sprint phases. It focuses on verifiable data exchange, contract-driven data exposure, and auditable governance while keeping the local optimization logic lightweight.
 
-Tests: tests/test_basic.py
+How to run tests
+- Install dependencies and test: pytest
+- Build package: python -m build
 
-How to run tests:
-  bash test.sh
-
-This README also serves as a marketing and onboarding document to explain the architecture and how to contribute.
-
-Notes on MVP extensions (EnergiBridge focus):
-- EnergiBridge provides a canonical interoperability layer mapping GridGuard primitives to a CatOpt-like representation with Objects, Morphisms, and PlanDelta.
-- Attestation and DID-based identities are wired into AttestedAgent and governance flows; key rotation and hardware-backed attestations are supported in MVP form.
-- Verifiable optimization is stubbed with a ZK-proof placeholder; privacy budgets and secure aggregation hooks are available for exploration.
-- Governance ledger supports append-only entries with signatures and public anchoring options.
+The MVP is intentionally small but production-ready: it uses clean interfaces, versioned contracts, and a simple delta-sync protocol with a cryptographic-proof stub.
