A Living Website writes and publishes on its own. That only compounds into something worth owning if every page it ships clears one bar: genuinely useful, and free of fabrication. We enforce that bar with gates, small deterministic checks a page has to pass before it goes live. We run them on this site first. Then we open-source them. These are those tools.
2 tools live, and the list grows as we harden more of the pipeline.
A read-only check that fails your build when writing carries the typographic and lexical tells of machine-drafted text: the em dash, the curly quote, invisible unicode, and a tuned set of phrase tells. It scores nothing. A flag is a fact about the text, a specific character or phrase that is present, not a probability that could be wrong.
A read-only check that fails your build when copy states a statistic nobody sourced. It extracts every data-claim, percentages, money, multipliers, ratios, scale words, and requires each one to trace to a cited source-pack manifest: claim, value, URL. The sister gate to de-AI gate: that one catches machine-written style, this one catches machine-invented facts.
The honest way to prove a website is honest is to show the check, not to assert the result. Every tool here runs against this site's own build before anything ships, and against its own source, so its documentation cannot smuggle the tell it warns about.
Open-sourcing them is the point. A gate you can read, run, and wire into your own pipeline is a claim you can verify instead of trust. See how the whole engine works on How it works, or watch it in public on Proof.
