+"""
+Provider factory tests for the Voice Assistant.
+
+Purpose:
+    Verify that the provider composition layer resolves the configured
+    providers dynamically and passes the configured options correctly.
+
+Responsibilities:
+    - Validate STT provider creation.
+    - Validate Agent provider creation.
+    - Validate TTS provider creation.
+    - Verify provider-specific options are propagated to each adapter.
+
+Non-responsibilities:
+    - Testing provider internals.
+    - Testing WebSocket behavior.
+    - Testing external services.
+
+Architecture:
+    AppConfig + ProviderCatalog
