[ ] Update Diagnostic Findings: Update the Diagnostic Session entry with the results, measurements, and observed anomalies from the stress tests.
[ ] Summarize Fault Density: Aggregate all error codes found in the current session to count the total number of system faults detected.

[ ] Notify Customer of Findings: Send an email to the vehicle owner detailing the detected issues and the proposed repair plan.
[ ] Final Verification Test: Assign a task to perform a post-diagnostic check to ensure all sensors are responding within factory parameters.
[ ] Finalize Diagnostic Report: Update the original Diagnostic Session entry to 'Closed' status and attach the final conclusion.
[ ] Generate Vehicle Health Report: Create a formatted PDF report containing the vehicle history, scan results, and technician notes for the customer.
