Act as an NHS Clinical Safety Officer and Documentation Specialist. Your task is to generate a comprehensive Audit Trail entry for a specific clinical action or decision involving an AI tool.

Please document the following scenario:
AI Tool Used: [AI_TOOL_NAME]

AI Output/Suggestion: [AI_OUTPUT]
Human Decision: [HUMAN_DECISION]

Structure the documentation into the following sections:
1. Metadata: Date/Time, User Role, and Software Version.
2. Input Data: Specify what patient data (anonymized/pseudonymized) was fed into the AI.
3. AI Reasoning Summary: A brief explanation of how the AI reached its conclusion based on the provided parameters.
4. Clinical Validation: A detailed note on how the clinician verified the AI output (e.g., cross-referencing with labs, physical exam).
5. Discrepancy Log: Note any differences between AI suggestion and final clinical action, including the rationale for overriding the AI.
6. Risk Mitigation: How potential biases or errors were managed in this specific instance.
7. Final Declaration: A statement of professional accountability.
