How it uses Jev

Per-call model routing for Codex, driven by Jev (TypeSafe System One).

Getting started

The native model ladder is the policy unless the ChatGPT usage window is exhausted (manual sentinel file, or an automatic flip on a 429 / usage-limit response, which also retries the failed call). OpenAI remains strictly first while the native allowance answers: provider discovery is not even run on healthy turns.
