+CATOPT-GRAPH AGENTS
+
+Overview
+- This repository contains a minimal, working MVP of CatOpt-Graph: a graph-calculus-inspired orchestration layer for compositional optimization across edge devices.
+- The MVP focuses on a simple asynchronous-like ADMM-lite solver, contract primitives (Objects, Morphisms, Functors), and two starter adapters (rover and habitat) that map to canonical representations.
+
+Architecture (high-level)
+- core: Objects, Morphisms, Functors, and a tiny contract registry skeleton.
+- admm_lite: a lightweight, fault-tolerant, delta-sync solver for two agents solving a simple distributed objective with a shared constraint.
+- adapters/: two starter adapters (rover and habitat) provide readState/exposeLocalProblemData/applyCommand interfaces.
+- transport: placeholder TLS/REST-like transport surface (mocked in MVP).
+- governance: lightweight auditing placeholder.
+- tests: unit tests for the ADMM-lite core.
+
+How to run tests
+- Ensure Python 3.10+ is installed.
+- Run: bash test.sh
+
+Development workflow
+- Use the provided DAG of modules to extend adapters and add new ones.
+- All changes should be backed by tests.
+
+Note
+- This is a minimal, opinionated MVP to bootstrap cross-domain interoperability. It is not a full production system.

+Graph-Calculus-Driven Compositional Optimization Studio for Edge Meshes
+
+Overview
+- CatOpt-Graph provides a minimal, pragmatic MVP for compositional optimization across edge meshes. It introduces a light-weight ontology (Objects, Morphisms, Functors) and a tiny ADMM-lite solver that demonstrates delta-sync/for reconnections while converging on a simple global constraint.
+
+What you get in this MVP
+- Core ontology scaffolding: Object, Morphism, Functor, and a tiny versioned contract registry.
+- 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.
+- Lightweight governance/contract conformance scaffolding.
+- Basic transport surface (mocked for MVP) and tests.
+
+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
+
+Long-term vision (brief)
+- Protocol skeleton bridging to Open-EnergyMesh/runtime, a Graph-of-Contracts registry, API bindings for adapters, and a simulated HIL environment with Gazebo/ROS.
+
+This README is a marketing and onboarding document for the MVP. The code is intentionally minimal but designed to be incrementally extended towards a working cross-domain orchestration platform.
+
+Package metadata
+- The Python package name is catopt-graph-graph_calculus_driven_compo per the repository requirements.
+- See pyproject.toml for build configuration and packaging details.
+
+License
+- This MVP is provided as-is for exploration and testing purposes.
+
+Contributing
+- See AGENTS.md for architectural guidance and test commands.
