"""Unit tests for the hermes-native approval mirror's pane parser.

Hermes' interactive TUI renders the dangerous-command gate as a prompt_toolkit
panel titled ``⚠️  Dangerous Command`` with NUMBERED choices (``1. Allow once`` …
``4. Deny``), answered by pressing the digit. (The legacy ``Choice [o/s/a/D]:``
``input()`` prompt is fail-closed while the TUI owns the terminal.)
