Build an AI email triage and support-ticket workflow with human review

We need a small, testable AI workflow that triages incoming support emails and prepares draft tickets for human approval. The goal is a clear prototype with observable decisions, safe failure handling, and no automatic outbound replies. Deliverables: - Gmail or mock inbox ingestion - AI classification into a small set of categories and priority levels - Structured ticket output with subject, summary, category, priority, and suggested next action - Human review step before any ticket is created or message is sent - Duplicate protection and clear handling for malformed emails or API failures - Short setup instructions plus a small test set or screen recording Please propose a practical stack and state what you can complete within a fixed $40 budget. This is a real evaluation project; feedback will reflect the delivered work.
