 This repository implements a production-ready skeleton for OpenEnergySphere's federated, contract-driven cross-domain energy planning platform. The MVP focuses on the EnergiBridge interoperability layer, mapping OpenEnergySphere primitives to a canonical IR and enabling plug-and-play adapters across DERs, meters, pumps, and buildings while preserving offline-first operation and governance.
 
+Note: Added a minimal EnergiBridge mapper (EnergiBridgeMapper) to illustrate canonical mappings between LocalProblem objects and a vendor-agnostic IR. This enables straightforward extension to more complex cross-domain workflows and adapters.
+
 Architecture highlights
 - Core primitives: LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog
 - Graph-of-Contracts registry for adapters and data schemas with per-message metadata
