+"""Lightweight Graph-of-Contracts (GoC) registry skeleton.
 
-This module provides a minimal in-process registry for contracts/adapters
-and a factory to produce a skeleton GoC structure embedded in the IR.
-The goal is to enable the core DSL -> IR path to be testable and
-extensible without introducing heavy dependencies.
+This module provides a minimal, production-friendly GoC skeleton that the
+core.IR translator can attach to the IR for auditability and future
+interoperability with adapters.
+
+The implementation is intentionally small and dependency-free to avoid
+introducing external runtime requirements in MVP environments. It exposes:
+- GoCRegistry: a tiny in-process registry interface (minimal feature-set).
+- build_minimal_goC_skeleton(digest, generated_at): a function that returns a
+  deterministic skeleton structure embedding the given digest and timestamp.
