"""Regression tests for profile-scoped TTS default output dir (#98749).

``DEFAULT_OUTPUT_DIR`` was resolved once at import time, so long-lived
multi-profile runtimes (dashboard console, TUI/Desktop backend, cron, kanban
workers) kept writing synthesized audio into the launch profile's
``cache/audio`` even while the request was scoped to a different profile via
``HERMES_HOME`` or ``set_hermes_home_override()``. The call-time accessor
``_default_output_dir()`` re-resolves from the live profile-scoped home;
these pins keep the synthesis paths from re-freezing the launch profile.
