"""EnergiaBridge: Canonical bridge between GridVerse primitives and a vendor-agnostic
|
|
interoperability layer (CatOpt-style).
|
|
|
|
This is a minimal, production-ready skeleton intended to anchor the interoperability
|
|
story described in the GridVerse MVP plan. It provides small, well-defined mapping
|
|
points between GridVerse core contracts (Objects, Morphisms, PlanDelta, etc.) and a
|
|
canonical representation used by potential adapters and external runtimes.
|
|
|
|
Note: This module is intentionally lightweight. Real deployments should augment the
|
|
mapping logic with proper schema validation, versioning, cryptographic attestation,
|
|
and TLS transport glue.
