Code that can spend money

That phrase should make you nervous. It made me build the rails first.

What I built

A Kalshi prediction-market scanning agent in pure Python. One pipeline: fetch markets, hard filters, edge scoring, action classification — PASS, WATCH, SMALL, HIGH-CONVICTION — then risk rules, then logging. Orders submit only when DRY_RUN is off AND the risk rules allow, and only through place_order_safely(), which carries a settlement-clarity blocklist.

The honest lesson

It's a prototype, and the thesis holds either way: when code can spend money, the safety rails ARE the product. The scanner finds the edge. The rails decide whether anything happens about it.
