Built by the guy who answers for the water.
Code Blue is built by a working commercial pool supervisor in Las Vegas — the person responsible when a resort pool goes green, a controller overfeeds acid, or a health inspector walks the deck. Every tool started as a real problem on a real route.
Test first. Dose with proof. Document everything.
