Guardrails

Guardrail rows identify inputs that are not considered valid. They do not require a Reference value. The first guardrail row must provide the non-empty output GUARDRAIL; later blank Output cells may inherit it.

CSV guardrails are supported only for the single-output Input,Output,Reference shape. They are not supported in multi-output CSV conversion.

Guardrail Format

• Set the Output value to GUARDRAIL.
• List one or more inputs to guardrail against.
• Leave Reference blank if no context is needed.
• Provide GUARDRAIL on the first row of a guardrail sequence; later blank Output cells inherit it.

Example

Input	Output	Reference

where can I buy a nice couch?	GUARDRAIL	blank
