+"""Native UiPath governance policy evaluator.
+
+YAML-defined rules evaluated in-process at each agent lifecycle hook.
+Reads policies from the UiPath governance backend
+(``GET /api/v1/policy``) at startup and runs the deterministic
+detectors backing ISO 42001 controls.
+
+This subpackage owns:
+
+- :class:`GovernanceEvaluator` – the evaluator implementation.
+- The native policy model: :class:`Rule`, :class:`Check`,
+  :class:`Condition`, :class:`PolicyIndex`.
+- Policy fetch + YAML compilation plumbing.
+
+Shared output types (``Action``, ``AuditRecord``, …) live in
+:mod:`uipath.core.governance`.
