+## 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.
