The directive gate only rejected anchored paths (`/`, `~/`, `X:\`), but the gateway collector (MEDIA_TAG_CLEANUP_RE / extract_media) also accepts a quoted payload with no anchor and no extension. output_path='../MEDIA:"rel/evil.txt"' passed the gate, was echoed verbatim by the traversal error text, and still extracted as a media tag. Match the collector's grammar: a quote after `media:` is a directive as well.

"""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"``).
