Please structure your response with the following sections:

1. SERVICE ARCHITECTURE: Define the end-to-end patient journey, from initial diagnosis upload to the delivery of the AI-enhanced second opinion report.
2. CLINICAL GOVERNANCE: Detail how the service adheres to DCB0129 and DCB0160 standards. Explain the 'Human-in-the-loop' mechanism where UK-registered GMC consultants validate AI outputs.
3. UK COMPLIANCE & DATA: Outline the strategy for UK GDPR compliance, Cyber Essentials Plus, and data residency requirements. Specify how the service handles sensitive 'Special Category' health data.
4. INSURANCE INTEGRATION: Propose a model for how this service integrates with UK Private Medical Insurance (PMI) providers like Bupa, AXA, or Aviva. Include CPT/ICD-10 coding considerations and claims automation.
5. TECHNICAL STACK: Recommend a secure cloud infrastructure (e.g., AWS London Region or Azure UK South) and the type of LLM/RAG architecture needed for medical accuracy.
6. RISK MITIGATION: Identify three primary risks (e.g., algorithmic bias, diagnostic overshadowing) and provide specific mitigation strategies for each.

Constraints: The service must be compatible with the UK's 'Right to Choose' or private healthcare pathways. Avoid generic advice; focus on UK-specific regulations (CQC, MHRA, and NICE guidelines).
