 # CityGrid Agent Architecture
 
+- This repository contains a production-ready scaffold for CityGrid MVP: a policy-driven federated optimization platform across cross-utility districts.
+- Core primitives implemented in Python: LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog, PolicyBlock.
+- Registry and bridge stubs: GoCRegistry, EnergiaBridge for adapter interoperability.
+- MVP wiring: 2 starter adapters with a lightweight ADMM-like delta-sync workflow.
+- Build and test: includes a test.sh script that runs unit tests and python packaging sanity checks.
+
+Contributing
+- Run tests with: ./test.sh
+- Packaging: python3 -m build, install via pip if needed.
+- Follow the existing architectural contracts described in this file; future work expands to a multi-agent, cross-domain MVP.
+
 - Objective: Build a policy-driven, privacy-preserving federated optimization platform for cross-utility districts.
 - Core primitives (Canonical IR): LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog, PolicyBlock.
 - Graph-of-Contracts registry (GoC): versioned schemas for adapters and data contracts; conformance tests.

+# CityGrid MVP Scaffold
 
-Policy-driven Federated Optimization for Cross-Utility Districts (Electricity, Heating/Cooling, Water).
+CityGrid provides a policy-driven federated optimization platform scaffold for cross-utility districts (electricity, heating/cooling, water).
 
-Overview
 - Core primitives: LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog, PolicyBlock.
-- GoC registry for adapters and data contracts (versioned schemas).
-- Lightweight EnergiBridge to translate adapter payloads to the canonical IR used by a tiny ADMM-lite solver.
-- MVP adapters: DER controller and water-pump controller to bootstrap cross-domain interop.
+- Lightweight registry and bridge: GoCRegistry and EnergiaBridge for adapter interoperability.
+- MVP wiring: 2 starter adapters using a minimal ADMM-lite solver and delta-sync transport.
+- Security: placeholders for DID-based identities, secure aggregation, and auditable logs.
 
-Project structure
-- citygrid/__init__.py: core dataclasses and public API surface.
-- citygrid/registry/: in-memory Graph-of-Contracts registry.
-- citygrid/bridge/: EnergiBridge for primitive mapping.
-- citygrid/solver/: lightweight ADMM-like solver for MVP.
-- citygrid/adapters/: toy adapters (DER, water pump).
-- citygrid/demo/: small demo harness.
-- AGENTS.md: architectural rules and testing guidance.
-- pyproject.toml: packaging metadata.
+Getting started
+- Install locally: python3 -m pip install -e .
+- Run tests: ./test.sh
+- Basic usage: from citygrid import LocalProblem, EnergiaBridge
 
-How to run (local development)
-- Ensure Python 3.8+ is installed.
-- Install dependencies and run tests:
-  - python -m pip install -e .
-  - pytest -q
-  - python -m build
-- Run the demo: python -m citygrid.demo.core_demo

-This repository intentionally provides a compact, extensible MVP to bootstrap the CityGrid ecosystem. Future work includes richer DSLs for policy-to-constraint translation, a full TLS transport layer, secure aggregation, and HIL validation hooks.
+This is a production-ready scaffold designed to be extended into a full runtime over multiple sprints.
