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. diff --git a/adapters/habitat/__init__.py b/adapters/habitat/__init__.py new file mode 100644 index 0000000..3e76563 --- /dev/null +++ b/adapters/habitat/__init__.py @@ -0,0 +1,8 @@ +"""Habitat starter adapter scaffold""" + +class HabitatAdapter: + def exposeLocalProblemData(self): + return {"local_problem": {}} + + def applyCommand(self, cmd): + return {"applied": cmd} diff --git a/adapters/rover/__init__.py b/adapters/rover/__init__.py new file mode 100644 index 0000000..cb1731b --- /dev/null +++ b/adapters/rover/__init__.py @@ -0,0 +1,5 @@ +"""Rover starter adapter scaffold""" + +class RoverAdapter: + def readState(self): + return {"status": "ok"} diff --git a/admm_lite/__init__.py b/admm_lite/__init__.py new file mode 100644 index 0000000..2e81a75 --- /dev/null +++ b/admm_lite/__init__.py @@ -0,0 +1,5 @@ +"""ADMM-Lite package initializer. + +This file makes the admm_lite directory a Python package so tests +and importers can reference modules like `admm_lite.solver`. +""" diff --git a/admm_lite/solver.py b/admm_lite/solver.py new file mode 100644 index 0000000..6605e93 --- /dev/null +++ b/admm_lite/solver.py @@ -0,0 +1,19 @@ +from __future__ import annotations + +from typing import Tuple + +def admm_step(x: float, y: float, u: float, rho: float, a: float, b: float) -> Tuple[float, float, float]: + # Simple quadratic objective example: + # minimize 0.5*a*x^2 + 0.5*b*y^2 + # with constraint x + y = 1 + # Standard ADMM update on a toy problem to illustrate API: + # x^{k+1} = argmin_x L_gamma(x, y^k, u^k) + # For demonstration, perform a plain projection step toward constraint and dual update. + # This is intentionally tiny and not a production solver. + # Update primal via a simple gradient-descent-like projection + x_new = (1.0 -
