# Q1: True Agreement
(AI Correct / Doctor Correct)

Layered Three-Tier ML Stack Performance Impact (Your Proposed Design): Explainable Baseline Sync: The VKIST Grader computes the numerical matrices & the GradCAM. The LLM Explainer parses the raw segmentation parameters  + GradCAM and automatically generates an interactive diagnostic draft chat panel & LLM based on the GradCAM + RAG-knowledge  + the raw-ultrasound to explain the VKIST-grader. The RAG-Referee confirms zero clinical guidelines variance, and logs a high-trust concur structural block.  <note both LLM have to record back the Chain-of-Though for explain why the LLM’s agree & allow the result)
