+"""Governance integration for ``uipath-langchain``.

+Exposes :class:`GovernanceCallbackHandler` — a LangChain callback
+handler that calls an :class:`~uipath.core.adapters.EvaluatorProtocol`
+on the model and tool lifecycle. Wired into a run by passing an
+``evaluator`` to :class:`UiPathLangGraphRuntimeFactory`; the factory
+builds the handler and hands it to the runtime through the existing
+``callbacks`` channel.
+
+Importing this module has no side effects: no adapter is registered,
+no global state is mutated.
