+### EnergiBridge Interoperability (Optional Reference)
+
+- EnergiBridge provides a canonical, lightweight bridge between GridVerse primitives and a vendor-agnostic intermediate representation (IR).
+- It enables plug-and-play adapters and a Graph-of-Contracts registry to interoperate with external backbones (e.g., Open-EnergyMesh, CatOpt).
+- Core mappings (illustrative):
+  - Objects -> LocalProblems (per-site optimization tasks)
+  - Morphisms -> SharedVariables / DualVariables (signals and priors)
+  - PlanDelta -> incremental decisions with metadata (timestamp, contract_id, signature)
+  - Limits/Colimits -> global constraints layer and policy hooks
+  - AuditLog / PrivacyBudget -> governance and audit trails per message
+
+- MVP hook: EnergiBridge provides to_ir / from_ir translations and a minimal bootstrap_contracts helper to seed a registry with basic schemas.
+- Starter adapters (DER, Building Load, etc.) wired through the Adapter Marketplace can consume/emit the canonical IR for cross-domain optimization.
+- Next steps (phased):
+  1) Integrate EnergiBridge mappings into the GraphContractRegistry conformance flows.
+  2) Add lightweight tests for to_ir / from_ir translations.
+  3) Expand the registry to support per-message metadata for auditability and replay protection.
