"""Tests for the auxiliary-model configuration UI in ``hermes model``.

Covers the helper functions:
  - ``_save_aux_choice`` writes to config.yaml without touching main model config
  - ``_reset_aux_to_auto`` clears routing fields but preserves timeouts
  - ``_format_aux_current`` renders current task config for the menu
  - ``_AUX_TASKS`` stays in sync with ``DEFAULT_CONFIG["auxiliary"]``

These are pure-function tests — the interactive menu loops are not covered
here (they're stdin-driven curses prompts).
