 - `Invariant-Guardrail-Service-Authorization`: Additional header value to specify a different API key to use for Guardrails evaluation specifically. `Invariant-Authorization` will then only be used to interact with the configured Explorer instance, not for guardrailing.
 - `Invariant-Guardrails`: Guardrailing rules to be checked for a specific request. This list of rules will replace all rules being evaluated, i.e. no additional rules will be pulled from [Explorer](https://explorer.invariantlabs.ai).
