+"""Audit sink framework for governance events.
+
+This module provides a pluggable audit system that supports multiple
+output destinations (sinks) for governance events. Events are emitted
+to all registered sinks, allowing flexible audit trail configuration.
+
+Usage::
+
+    from uipath.runtime.governance.audit import get_audit_manager, AuditEvent
+
+    # Get the global audit manager
+    manager = get_audit_manager()
+
+    # Emit an event (goes to all registered sinks)
+    manager.emit(AuditEvent(
+        event_type="rule_evaluation",
+        trace_id="abc-123",
+        agent_name="my-agent",
+        data={"rule_id": "ASI-01", "matched": True},
+    ))
+
+    # Register a custom sink
+    manager.register_sink(MyCustomSink())
+
+Built-in sinks:
+
+- :class:`TracesAuditSink`  – OpenTelemetry spans for Orchestrator Traces UI
+- :class:`ConsoleAuditSink` – stderr output for debugging
+
+Sink registration:
+
+- The ``traces`` sink (OpenTelemetry spans → Orchestrator audit UI) is
+  **platform-mandated** and always registered. It cannot be disabled by
+  a developer-side env var — governance is platform-owned.
+- The ``console`` sink is a developer aid for local debugging and is
+  opt-in via env var.
+
+Environment variables (developer-facing, console only):
+
+- ``UIPATH_AUDIT_VERBOSE`` – verbose console output.
+- ``UIPATH_GOVERNANCE_CONSOLE_LOG`` – enable the console sink.
