"""Tests that verb command fallback defaults match valid CodeMapper values.

Verbs in verbs.py use `xxx or "fallback"` patterns to provide defaults
when the user doesn't specify an option. These fallbacks must match the
valid names in core/constants.py CodeMapper instances, otherwise the
downstream service/core layer will reject them.
