  "_README": "Models to sample. `id` is the (stable) folder name under corpus/samples/. The model VERSION to call comes from the `modelEnv` env var (set it in .env, e.g. XAI_MODEL=grok-4) so you can bump model versions without editing this file; `model` here is only the fallback default if that env var is unset. `key` is the env var holding the provider's API key (never commit keys). A model whose key is unset is skipped.",
