 # CatOpt-Graph MVP
 
-Graph-Calculus-Driven Compositional Optimization Studio for Edge Meshes
+This repository hosts a minimal, testable MVP of CatOpt-Graph: a graph-calculus-inspired orchestration layer for compositional optimization across edge devices.
 
-Overview
-- CatOpt-Graph provides a minimal, pragmatic MVP for compositional optimization across edge meshes. It introduces a lightweight ontology (Objects, Morphisms, Functors) and a tiny ADMM-lite solver that demonstrates delta-sync and reconnection semantics while converging on a simple global constraint.
-
-What you get in this MVP
-- Core ontology scaffolding: Object, Morphism, Functor, and a tiny versioned ContractRegistry.
-- ADMM-lite solver: asynchronous, two-agent solver with bounded staleness and deterministic reconciliation on reconnects.
-- Adapters: rover and habitat stubs that map to a canonical representation.
-- Governance scaffolding: lightweight conformance checks and audit-friendly data flow.
-- Transport surface: a minimal TLS/REST-like mock transport for MVP testing.
-- Tests: unit tests for the ADMM-lite core and contract registry.
+- Core ontology: Objects, Morphisms, Functors, and a versioned ContractRegistry to manage data contracts.
+- Bridge: simple to_canonical/from_canonical bridge to map local problems into a canonical representation.
+- ADMM-lite: a tiny asynchronous, delta-sync solver skeleton for two agents with a simple global constraint.
+- Adapters: scaffolded rover and habitat adapters ready for extension.
+- Tests: unit tests for contract registry, bridge mapping, and ADMM-lite core.
 
 How to run
-- This project is Python-based. See test.sh for the test runner which also builds the package to validate packaging metadata.
-- After cloning, run: bash test.sh
+- Prerequisites: Python 3.10+, pip, and a POSIX shell.
+- Run tests: bash test.sh
+- Build package: python3 -m build
 
-Roadmap (MVP, 8–12 weeks)
-- Phase 0: Core ontology, 2 adapters (rover, habitat), ADMM-lite core, delta-sync scaffold.
-- Phase 1: Global constraints layer (Limits/Colimits) and governance ledger.
-- Phase 2: Bridge to cross-domain runtimes (Open-EnergyMesh/GridVerse-like ecosystems) and a canonical transport.
-- Phase 3: HIL validation with Gazebo/ROS and minimal cross-domain demos.
-
-Architecture snapshot
-- Core: Objects, Morphisms, Functors, Limits/Colimits skeleton, and a versioned ContractRegistry.
-- ADMM-lite: two-agent solver with delta-sync and deterministic reconciliation on reconnects.
-- Adapters: rover and habitat stubs exposing a minimal interface readState, exposeLocalProblemData, applyCommand.
-- Bridge: mapping between domain LocalProblem data and a canonical CatOpt representation.
-- Governance: auditing and contract conformance scaffolds.
-- Transport: mock TLS/REST-like surface for MVP integration.
-- Tests: unit tests for core components and end-to-end tests for the ADMM-lite flow.
-
-Extending the MVP
-- Add new adapters and register them in the ContractRegistry.
-- Enhance the bridge with richer to_canonical/from_canonical mappings for domain data.
-- Introduce additional data contracts (SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog).
-- Add a lightweight HIL simulation layer (Gazebo/ROS) for offline testing.
-
-Packaging and metadata
-- The Python package name is catopt_graph_graph_calculus_driven_compo, as defined in pyproject.toml.
-- See pyproject.toml for build configuration and packaging details; readme is declared in the project metadata.
-
-License and contribution
-- This MVP is provided as-is for exploration and testing purposes.
-- See AGENTS.md for architectural guidance and test commands.
-
-Notes
-- This README is a living document. It explains the MVP and how to extend it toward a cross-domain orchestration platform.
+This MVP is intentionally small and opinionated to enable rapid iteration and interoperability testing with other ecosystems.
