+GridVerse MVP Roadmap
+
+Overview
+- This document outlines the practical, production-oriented roadmap for the GridVerse MVP, focusing on cross-domain energy optimization with a graph-contract registry and an adapter marketplace. It mirrors the design described in the project brief and aligns with the current repository structure (Objects, Morphisms, Functors, a lightweight ADMM-like solver, and a TLS-ready EnergiBridge).
+
+Phases and milestones (8–12 weeks)
+- Phase 0 (0–2 weeks): Protocol skeleton
+  - Finalize core primitives: Objects, Morphisms, PlanDelta, and small contract schemas.
+  - Publish 0.2 contract schemas and examples.
+  - Implement two starter adapters (e.g., a DER controller and a building load controller) with TLS transport placeholders.
+  - Wire a minimal ADMM-lite solver scaffold and delta-sync demo.
+  - Deliverables: DSL sketch, two starter adapters, EnergiBridge skeleton, basic conformance tests.
+
+- Phase 1 (2–4 weeks): Governance and conformance
+  - Introduce governance ledger scaffolding and a lightweight identity model (DID-like or short-lived certs).
+  - Implement a simple conformance harness to validate adapters against contract schemas.
+  - Implement secure delta-sync with bounded staleness for offline/partitioned operation.
+  - Deliverables: Governance scaffold, conformance tests, validated delta-sync demo.
+
+- Phase 2 (4–6 weeks): Marketplace and codegen stub
+  - Add adapter marketplace entry points, a minimal codegen path, and a reference UI sketch for graph-based device-constraint composition.
+  - Extend contract registry with versioning and per-message metadata for replay protection.
+  - Deliverables: Marketplace API, codegen stub, UI wireframes, extended registry contracts.
+
+- Phase 3 (6–12 weeks): Cross-domain pilot and HIL validation
+  - Introduce a simulated second domain (e.g., HVAC or water pumping) and demonstrate cross-domain planning.
+  - Conduct hardware-in-the-loop validation with 2–3 devices and measure plan quality, convergence, and latency.
+  - Deliverables: End-to-end cross-domain demo, KPI dashboards, and a publishable MVP package.
+
+Architecture notes
+- EnergiBridge: Canonical bridge that maps GridVerse primitives to a vendor-agnostic, CatOpt-inspired representation. Keys: Objects -> LocalProblems, Morphisms -> SharedSignals, PlanDelta -> incremental decisions, DualVariables -> coupling signals, Governance -> AuditLog.
+- Graph-of-Contracts registry: Versioned contracts and schemas with per-message metadata for replay protection and auditing.
+- Adapter Marketplace: Starter adapters plus user-contributed adapters. Each adapter exposes a clean interface and can be instrumented with a codegen fallback.
+- Simulation & HIL: Lightweight digital twin support and hardware-in-the-loop testbeds for cross-domain evaluation.
+
+Kickoff and collaboration
+- If you’d like, I can draft concrete toy contracts and a minimal two-adapter MVP to bootstrap EnergiBridge interoperability in this repo.
+- Owner roles, milestones, and a lightweight governance plan will be defined as soon as the team aligns on priorities.
+
+Usage alignment
+- The current repository already implements the MVP scaffolds (core contracts, registry, TLS-ready bridge, and starter adapters). ROADMAP.md serves as the living plan to guide future work and onboarding.
