Everything on this website

Garret: you texted me a screenshot and asked if the site was intentionally broken. It was actually broken. The homepage had been rendering a header and a footer with nothing in between since July 29th, because a page the theme pulls its whole body from got flipped to hidden during a security cleanup. It is fixed now.

Nothing else was down. This is the map of what was sitting behind that blank space.

The product

A bottle of reagent, a UV flashlight, and a color card. You spray or drip it on a painted dish, a windowsill, a toy. Lead pigment lights up bright green in about 30 seconds. The liquid is clear, the glow is locked to the decoration, and plain white ceramic does nothing.

Free tools, all running on real data

These are not blog posts with a lookup table pasted in. Every one of them queries a live database of test results I either ran myself, bought, or pulled out of state and federal reporting. Nobody has to buy anything to use them.

The teaching side of the site. Most people arrive scared and leave with a plan, and the plan is usually cheaper than they expected.

The chemistry and the paperwork

The part I get asked about by inspectors, chemists, and people who assume a color-change test is a gimmick.

The chemistryMethylammonium bromide in isopropanol. It grabs lead and forms a perovskite quantum dot that fluoresces green./perovskite-lead-detection XRF vs leach vs FluoroSpecHow to read three different kinds of lead result without fooling yourself./xrf-vs-fluorospec Patent disclosureThe trace-detection filing, written out./trace-detection-patent Safety data sheetThe real SDS, not a marketing summary of one./sds Safety and regulatoryWhat this is cleared for and what it is not./safety FAQThe questions that come in every week./faq-page

Institutions and writing

Health departments, code enforcement, and grant-funded programs are the side of this that is growing fastest. HUD's own numbers say the new dust limits raise remediation cost about 16 percent, and only about 13,000 homes a year get done at all.

How it gets built, since you asked about the agent setup

There is no page builder and no dev. Pages get written and pushed straight to Shopify through the Admin API from a terminal, which is why there are a thousand of them. The data behind the calculators lives in Postgres and the pages query it live, so updating a number updates every page that cites it.

The failure mode you caught is the flip side of that. Nothing on the site is watching itself. A page got hidden during a cleanup, the homepage quietly rendered empty for twenty days, and the first alert I got was your text message. That is getting fixed next.
