-# Interplanetary Edge Orchestrator: Privacy-Preserving Federated Optimization
+# Interplanetary Edge Orchestrator — Prototype
 
-This repository contains a minimal, working Python simulation of a privacy-preserving
+This repository contains a focused, test-covered prototype of two foundational pieces for the Interplanetary Edge Orchestrator:
-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.
 
-Usage highlights:
+- EnergiBridge-style canonical IR JSON schemas for LocalProblem, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, and AuditLog (module: interplanetary_orchestrator.ir).
-- Lightweight Client and Server implemented in Python.
+- 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).
-- 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).
 
-Privacy controls
+Purpose: provide a concrete, small, well-tested chunk of functionality that downstream agents can extend into adapters, transports, and governance layers.
-- 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.
 
-Enhancements added (Planning Lens MVP)
+Usage
-- 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.
 
-How to run tests:
+Run tests and build (the test runner also validates packaging):
-- This repository provides a test script via test.sh (see below).
+
+    ./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.
