+## EnergiBridge Interoperability (Skeleton)
+
+- Added gridverse/energi_bridge.py to provide a canonical bridge between GridVerse primitives and a vendor-agnostic intermediate representation (IR).
+- This skeleton demonstrates verbs for translating contracts to IR, and a small mapper to illustrate adapter wiring without hard coupling to solvers.
+- Use this as a reference when implementing cross-domain adapters and the Adapter Marketplace in Phase 0.
+
+Next steps:
+- Integrate EnergiBridge mappings into the GraphContractRegistry conformance flows.
+- Add lightweight tests for to_ir / from_ir translations.
+- Expand the registry to support per-message metadata for auditability and replay protection.
