CosmosMesh MVP

CosmosMesh is a privacy-preserving federated mission-planning scaffold designed for deep-space constellations. It targets offline-first operation with intermittent connectivity, enabling heterogeneous assets (rovers, aerial drones, habitat modules, orbiting satellites) to coordinate planning and resource usage without centralization.

Core ideas

• Local optimization problems (variables, objectives, constraints) with explicit data contracts and versioning.
• Federated optimization core: an ADMM-lite solver that exchanges only summarized signals to preserve locality.
• Lightweight global assembly: fleet-wide constraints (energy, time windows, safety) applied without re-deriving the entire global model.
• Delta-sync and offline resilience: deterministic reconciliation on reconnects with audit trails.
• Privacy-by-design: secure aggregation by default, optional local DP budgets, and role-based access controls.
• Identity & security: DID-based identities, short-lived certificates, and tamper-evident logging.
• Adapters & simulation: reference adapters for rover/habitat/space assets, plus a scenario simulator for offline validation.
• Open API and governance: schema registry for data contracts and a governance ledger to anchor decisions.

MVP plan (8–12 weeks)

• Implement a 2–3 asset testbed (rover, drone, habitat) with a simple quadratic objective and an ADMM-lite solver.
• Define data contracts: Telemetry, Forecast, Command, Event, and Trade-like signals with versioned schemas.
• Delta-sync protocol: deterministic reconciliation for intermittent links with per-message metadata and audit logs.
• Identity & security baseline: DIDs or short-lived certs, secure aggregation by default.
• Adapters and simulation: two starter adapters and a space-scenario simulator to evaluate convergence and resilience.
• Global constraints layer: light fleet-wide constraints that bind local problems during aggregation.
• MVP milestones: Phase 0 protocol/specs + 2 adapters; Phase 1 offline validation; Phase 2 cross-domain demo; Phase 3 HIL.
• Metrics: convergence speed, plan-optimality gap, delta-sync latency, and privacy budgets.

Getting started

• Build: python3 -m build
• Test: ./test.sh
• Explore: src/cosmosmesh_privacy_preserving_federated_/ and src/cosmosmesh_privacy_preserving_federated_/catopt_bridge.py for the MVP scaffolding and the CatOpt bridge (lightweight interoperability layer).

Notes

• This repo focuses on a safe, minimal surface suitable for rapid iteration. Extend with adapters for rovers, habitats, and orbital assets, plus a delta-sync protocol and a light global-assembly layer in follow-on work.

Changelog-style summary

• Added CatOptBridge (lightweight CosmosMesh -> CatOpt representation) in the MVP scaffold.
• Exposed CatOptBridge via the MVP package API for quick experimentation.
• Expanded README to reflect MVP architecture, extension paths, and evaluation plan.

Public artifacts
