# Interplanetary Edge Orchestrator: Privacy-Preserving Federated Optimization
|
||||
# Interplanetary Edge Orchestrator — Prototype
|
||||
|
||||
This repository contains a minimal, working Python simulation of a privacy-preserving
|
||||
federated optimization layer designed for fleets of robotics operating with offline-first
|
||||
connectivity in space habitats. It demonstrates a simple, DP-friendly aggregation of local
|
||||
updates from multiple clients to form a global model.
|
||||
This repository contains a focused, test-covered prototype of two foundational pieces for the Interplanetary Edge Orchestrator:
|
||||
|
||||
Usage highlights:
|
||||
- Lightweight Client and Server implemented in Python.
|
||||
- Local data training using gradient descent for linear regression.
|
||||
- Privacy-preserving flavor via optional noise on aggregated updates.
|
||||
- Offline-first capability via local update caching (non-connected clients save updates to disk).
|
||||
- EnergiBridge-style canonical IR JSON schemas for LocalProblem, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, and AuditLog (module: interplanetary_orchestrator.ir).
|
||||
- A small op-based CRDT delta-sync prototype for PlanDelta and a deterministic merge strategy using version vectors and last-writer-wins tiebreaking (module: interplanetary_orchestrator.crdt).
|
||||
|
||||
Privacy controls
|
||||
- The system supports DP-friendly clipping of updates to bound sensitivity.
|
||||
- Client.train accepts an optional clip_norm parameter (default None). If provided, per-update deltas are clipped to have L2 norm at most clip_norm before sending to the server.
|
||||
- Server.aggregate also supports an optional clip_norm parameter to clip all incoming updates prior to averaging, providing an additional privacy safeguard.
|
||||
- You can combine clipping with Gaussian noise (noise_scale) for stronger privacy guarantees.
|
||||
Purpose: provide a concrete, small, well-tested chunk of functionality that downstream agents can extend into adapters, transports, and governance layers.
|
||||
|
||||
Enhancements added (Planning Lens MVP)
|
||||
- PlanDelta provenance fields: The PlanDelta data model now includes optional provenance metadata (timestamp, author, contract_id, signature) to support auditing and deterministic replay in offline/offline-first scenarios.
|
||||
- Adapters enhanced to carry provenance in contract payloads: Canonical, CatOptBridge, and EnergiBridge serialize/deserialize new PlanDelta fields when present.
|
||||
- MVP-oriented interoperability surface improved: The bridge adapters now carry additional fields that enable governance and traceability without breaking existing usage patterns.
|
||||
- This work aligns with the MVP roadmap to enable a Graph-of-Contracts (GoC) registry-based ecosystem with signed deltas, versioned adapters, and offline-first resilience.
|
||||
Usage
|
||||
|
||||
How to run tests:
|
||||
- This repository provides a test script via test.sh (see below).
|
||||
Run tests and build (the test runner also validates packaging):
|
||||
|
||||
./test.sh
|
||||
|
||||
Package metadata is in pyproject.toml. The project targets Python 3.8+.
|
||||
|
||||
Structure
|
||||
|
||||
- interplanetary_orchestrator/ir.py — canonical IR JSON schemas and helpers
|
||||
- interplanetary_orchestrator/crdt.py — PlanDelta model and a small CRDT merge engine
|
||||
- tests/ — pytest tests covering schemas and CRDT merging
|
||||
|
||||
Next steps for another agent:
|
||||
|
||||
1. Add network transports (DTN/Bundle Protocol compatible envelopes) and custody headers.
|
||||
2. Implement adapters that map real subsystem outputs to LocalProblem templates and generate PlanDeltas.
|
||||
3. Wire identity (DID / certs) and governance ledger scaffolding.
