Unknown model: . Allowed

Error message

Unknown model: {model!r}. Allowed: {ALLOWED_MODELS}

What it means

Allowlist guard in run_scenario: the --model value is not in the ALLOWED_MODELS set, so the scenario runner refuses to launch claude -p with an untested model. The allowed values are echoed in the message.

Solutions

1. Use one of the models listed in ALLOWED_MODELS (e.g. sonnet)
2. Update ALLOWED_MODELS in the runner if a new model has been vetted
