# Closeout — AI That Refuses to Lie About Money

**Track:** Indie Developer

**Theme:** Build for Your World

**GitHub:** https://github.com/boscoj2008/meta-hackathon-closeout

Closeout is an AI-assisted financial investigator for small traders who finish the day with cash missing from their expected tally.

Built using Meta's Muse Spark through the Meta Model API, Closeout asks targeted investigative questions and extracts information from receipt photographs. The trader reviews the extracted evidence before a deterministic comparison engine evaluates whether it could explain the discrepancy.

In our synthetic demonstration, the trader counts 420 tokens against a tally of 510, leaving a 90-token difference. A cash-drop receipt for 90 tokens can mathematically explain the difference, but Closeout refuses to claim that the cash actually moved without further verification.

Unlike AI financial tools that present plausible guesses as facts, Closeout separates model interpretation, user-reviewed evidence, arithmetic consistency, and verified financial truth.

**Technology:** Meta Muse Spark 1.3, Meta Model API, Python standard library, JavaScript, HTML and CSS.

**Engineering:** 105 offline tests reported passing, bounded investigation turns, deterministic financial calculations, explicit uncertainty, and server-side API credentials.

**Limitations:** Demonstration uses synthetic data. Financial evidence is not independently authenticated. The app is currently run locally rather than publicly hosted.
