"""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"``).
