"""Regression tests for OpenAI Codex model validation when the listing lags behind
actually usable backend model IDs.

The bug: `/model` and `switch_model()` reject `gpt-5.3-codex-spark` because the
OpenAI Codex listing omits it, even though direct runtime calls with
`--provider openai-codex -m gpt-5.3-codex-spark` succeed.
