CosmosMesh MVP Roadmap

This document outlines a concrete, production-minded MVP plan to bootstrap CosmosMesh as described in the project brief. It complements the existing MVP skeleton in the repo and provides actionable milestones for incremental delivery.

Vision

• Privacy-preserving, offline-first federation for multi-asset space missions.
• Lightweight, vendor-agnostic bridge (EnergiBridge-like) mapping CosmosMesh primitives to a canonical IR.
• End-to-end delta-sync with deterministic replay for islanding and reconnection.
• Governance, identity, and secure aggregation baked in from the start.

MVP Phases (8–12 weeks)

Phase 0 — Core protocol and 2 starter adapters (4 weeks)

• Implement protocol skeleton and TLS transport between two starter adapters (e.g., rover_planner and habitat_module).
• Integrate a lightweight ADMM-lite coordinator on the edge.
• Establish end-to-end delta-sync path with deterministic replay for islanding.
• Deploy a toy objective (mesh energy balance, simple task allocation) to verify convergence.

Phase 1 — Governance and identity (4 weeks)

• Add governance ledger scaffolding and tamper-evident audit trails.
• Implement identity layer: DIDs or short-lived certificates for assets; per-message crypto-tags.
• Provide default secure aggregation settings for SharedVariables.

Phase 2 — Cross-domain demo and SDK (2 weeks)

• Extend adapters to cover a second domain (e.g., satellite domain) and demonstrate cross-domain coordination.
• Publish CosmosMesh SDK bindings (Python/C++) and a canonical transport.
• Provide a toy contract example and a reference transport layer.

Phase 3 — HIL and KPIs (2 weeks)

• Hardware-in-the-loop tests (Gazebo/ROS) across 2–3 devices.
• KPI dashboards for convergence speed, delta size, latency, adapter conformance, and governance auditability.

Architectural notes

• Canonical bridge (EnergiBridge-style): map CosmosMesh primitives to a vendor-agnostic CatOpt IR.
• GoC registry for adapter/versioning; codegen hooks to simplify adding new adapters.
• Minimal DSL seeds to bootstrap interoperability across adapters.

Risk and mitigations

• Data leakage: enforce secure aggregation and per-signal privacy budgets.
• Latency variance/partitions: bounded-staleness ADMM-lite with safe fallback.
• Compliance friction: lightweight governance and cryptographic signatures.

Success criteria

• End-to-end convergence on the toy objective across 2–3 adapters.
• Deterministic replay works across partitions and reconnects.
• Governance and identity mechanisms are exercised in demos.
• The repository provides a clear extension path to cross-vendor interoperability.

How to contribute

• Add or adjust adapters that implement the minimal interface: readState, exposeLocalProblemData, applyCommand.
• Extend the DSL sketch and GoC registry schemas.
• Write tests that exercise the delta-sync and ADMM-lite convergence in multi-adapter scenarios.

This roadmap is intentionally pragmatic: we ship a stable MVP quickly and expand features in well-scoped iterations.
