Module quality_gate 

Response quality validation with retry

Response Quality Gate

QualityGateProvider wraps an inner Box<dyn LlmProvider> and validates each response against a configurable QualityPolicy. If validation fails, the request is retried with feedback appended to help the provider correct its output. After exhausting retries, the last response is returned with finish_reason set to "quality_gate_exhausted".

Limitations

• Streaming responses (complete_stream) are passed through without quality checking, since the full content is not available upfront.
