Template Response Generator

Software componentCognitionCognition & Memoryarc:TemplateResponseGenerator

A fallback responder that returns a safe generic templated response when model-based generation fails.

Responsibility. Produces safe templated responses on generation failure.

Also known as: Template-based generation fallback, Fallback response, Uncertainty acknowledgment response, Standardized refusal message, Compliant fallback response, Fallback responses for unhandled cases
