The plain model names you already list in `models` keep catching outright errors, so existing fallbacks are unaffected. Confidence conditions cover Choice and Score questions. Boolean questions escalate on a probability range instead.\n\nSet the fallback by adding one conditional object to `providerOptions.gateway.models`. Requests without it keep their existing behavior.\n\nLeave out `question` and the condition checks every question of the matching type, so `{ \"confidenceBelow\": 0.6 }` escalates when any Choice or Score answer falls below 0.6.\n\nBecause a triggered fallback runs a second decision, it bills both stages.\n\nDecision fallbacks are in beta.
