A model correctly generates parameters for a refund tool. However, refunds are processed without verifying eligibility rules. What is missing from the design of the system?

Susquehanna River Bank recently launched an AI-powered assistant designed to streamline small business loan approvals. The assistant interacts directly with applicants through a conversational interface and makes instant approval or rejection decisions.  The bank states that the AI system eliminates the need for manual review in most cases.  The bank reports that decisions are made in under three seconds and describes the system as “fully autonomous.”According to the bank’s press release, the system works as follows:The AI model receives the applicant’s information (revenue, years in business, credit score, requested loan amount) through a web form.The entire applicant record is inserted into the model prompt.The system prompt contains a detailed description of the bank’s loan policies and approval thresholds.The model is instructed to:Evaluate the applicant.Decide whether to approve or reject the loan.Generate a written explanation for the decision.If the model outputs “APPROVED,” the system automatically disburses funds through the bank’s payment API.The system stores the entire conversation transcript in a log file for recordkeeping.Part 1:Identify and explain at least three architectural weaknesses or risks in the system described above.  For each issue clearly describe the flaw and explain why it is risky in a production financial setting.
