Build a single-page vendor security assessment dashboard for reviewing third-party vendors against HECVAT and DPA requirements. The goal is to give a security, legal, and procurement team one live command center that replaces scattered spreadsheets and email threads — a single view of where every vendor stands in the review pipeline and what needs attention. Trigger it as an HTTP webpage route (e.g. /dashboard) rendered as a React single-page app — no cron, upstream, or email trigger. The page should render immediately and, if you later wire in real data, fetch it from separate route steps rather than blocking on an upstream step. At a high level the dashboard should: Track vendors through a clear assessment pipeline (submission → automated validation → legal review → security review → clarification → approved), showing each vendor's current stage. Show top-line KPIs and trends — how many vendors are in flight, review throughput, and approval velocity. Surface an AI validation score per submission, flag fast-track candidates, and note pre-validated security certifications (SOC 2, ISO 27001, FedRAMP, PCI DSS, etc.). Monitor questionnaire currency (flag vendors on outdated HECVAT versions) and raise contract-renewal alerts for expiring agreements. Provide a per-vendor detail view with an audit trail of who did what and when. Design it as a polished, production-grade interface with a distinctive visual direction, not a generic template. Start it on seeded/illustrative demo data so the experience is fully explorable, and structure it so real vendor submissions and a datastore can be plugged in later. Where you'd extend it beyond demo data, treat these as swappable choices, not requirements: store vendor records in a datastore or persistent volume — or your team's system of record; run AI validation/summarization with a model provider like Anthropic Claude — or your preferred LLM; send renewal and clarification alerts to Slack — or your team's chat/email tool; ingest submissions via a web form or an intake tool of your choice. Tools used: React (single-page webpage route), seeded in-code demo data (no external connectors or APIs in the current build)
