+"""Regression: text_to_speech_tool output_path must reject '..' traversal.
+
+The TTS surface accepts agent/user-supplied absolute paths (writing to a
+chosen file is the whole point). What it must reject is paths that use
+``..`` components to escape their declared base — those are almost
+always either a bug or prompt-injection-controlled
+(e.g. ``output_path="audio/../../etc/cron.d/x"``).
