+"""EnergiBridge: minimal IR translator for CosmosMesh privacy-preserving federation
+
+This module provides a lightweight translator (to_ir) that converts a LocalProblemEP
+and associated signals (SharedVariableEP, DualVariableEP, PlanDeltaEP) into a CatOpt-
+style intermediate representation (IR) suitable for MVP testing and adapter wiring.
