ACME City Permits is a working municipal permitting system for a fictional city. It follows a permit from the applicant's form through intake, identity and property review, rule checks, a human decision, fee reconciliation and issuance. Five roles each see the step they own: applicant, agent operator, data steward, permit reviewer and city administrator. Intake and adjudication agents prepare each case and leave a recommendation, and Muse reads documents, proposes record matches, answers applicant questions with citations, and explains results in plain words. Muse proposes. People decide. The model never approves, prices or issues a permit. It is built for production: rate limits, call caps, audit history, a durable work queue and 3,839 passing tests. Live demo, no login or API key needed: https://acme-city-permits.onrender.com

▎ Bonus prize targeted: Best Agentic Use-Case.
