- * This contains:
- * - Static type checks to verify the Spec's types are compatible with the SDK's types
- *   (mutually assignable, w/ slight affordances to get rid of ZodObject.passthrough() index signatures, etc)
- * - Runtime checks to verify each Spec type has a static check
- *   (note: a few don't have SDK types, see MISSING_SDK_TYPES below)
