# OpenFederatedCompiler: Architecture and Contribution Guide
|
||||||
|
|
||||||
|
Overview
|
||||||
|
- A multi-agent, privacy-preserving policy compiler MVP intended to federate policy across edge devices.
|
||||||
|
- Core primitives: LocalPolicy, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, AuditLog, PolicyBlock, Graph-of-Contracts.
|
||||||
|
- Delta-sync via CRDT-like merge to support offline islanding and deterministic replay on reconnect.
|
||||||
|
- Adapter registry (Graph-of-Contracts) to manage protocol contracts and compatibility.
|
||||||
|
|
||||||
|
Tech Stack (Python-based MVP)
|
||||||
|
- Language: Python 3.8+ for rapid prototyping and strong typing with dataclasses.
|
||||||
|
- Core modules: idea157_openfederatedcompiler_privacy_preserving (core library).
|
||||||
|
- Tests: pytest-based unit tests.
|
||||||
|
- Packaging: pyproject.toml with setuptools.
|
||||||
|
|
||||||
|
Testing and Commands
|
||||||
|
- Run unit tests: bash test.sh
|
||||||
|
- Build package: python3 -m build (requires build package)
|
||||||
|
- Lint: Not included yet; extend later with flake8/ruff if needed.
|
||||||
|
|
||||||
|
Repository Structure (high-level)
|
||||||
|
- pyproject.toml: Packaging metadata and build-system config.
|
||||||
|
- README.md: Project overview.
|
||||||
|
- AGENTS.md: This document.
|
||||||
|
- READY_TO_PUBLISH: Marker file once the MVP is complete and ready for publishing.
|
||||||
|
- idea157_openfederatedcompiler_privacy_preserving/: Core library package (Python).
|
||||||
|
- tests/: Test-suite root.
|
||||||
|
|
||||||
|
Contribution Rules
|
||||||
|
- Do not modify core architecture without signaling intent and updating tests.
|
||||||
|
- Keep changes minimal and well-scoped.
|
||||||
|
- Ensure tests pass before proposing further changes.

# OpenFederatedCompiler: Privacy-Preserving Cross-Device Policy Compiler (MVP)
|
||||||
|
|
||||||
Source logic for Idea #157
|
This repository implements a production-oriented, privacy-preserving policy compiler MVP designed to federate policy translation across edge devices. The MVP focuses on a canonical contract language, a Graph-of-Contracts registry for adapters, a CRDT-like delta-sync mechanism for offline updates, and a portable codegen backend scaffolding.
|
||||||
|
|
||||||
|
Key concepts implemented in this MVP:
|
||||||
|
- LocalPolicy, SharedVariables, PlanDelta and related primitives as seed artifacts
|
||||||
|
- A tiny CRDT-style merge engine to apply PlanDelta to LocalPolicy
|
||||||
|
- Graph-of-Contracts registry skeleton for adapter versioning and domain compatibility
|
||||||
|
- TLS-ready abstraction scaffolding for secure transport (conceptual in this MVP)
|
||||||
|
- Back-end stubs for codegen (C, Rust, MicroPython) via a simple placeholder layer
|
||||||
|
|
||||||
|
How to use:
|
||||||
|
- Run tests via: `bash test.sh`
|
||||||
|
- The package is structured for production-grade extension; see AGENTS.md for contribution guidance.
|
||||||
|
|
||||||
|
This project is intended as a robust foundation rather than a finished product. It demonstrates the architecture and safety guarantees needed for interoperable, privacy-preserving policy enforcement across heterogeneous edge ecosystems.
|
||||||
|
|
||||||
|
Developer notes:
|
||||||
|
- Language: Python (production-friendly, extensive library support)
|
||||||
|
- Packaging: pyproject.toml with setuptools
|
||||||
|
- Entry points: None yet (core library focus with tests)
|
||||||
|
|
||||||
|
See AGENTS.md for architecture details and contribution guidelines.
