# Kiln

> Raw in, verified out. Kiln is the verify engine behind these products: a source
> document goes in, Kiln pulls out the claims, checks every quote against the text it
> came from, has a second model score it, and a person signs off. One run is a bake.
> Four stages run in order — read, structure, verify, finish — and a stage that isn't
> finished doesn't hand its piece forward; a claim that fails is repaired or dropped,
> never waved through. The verify stage is two separate checks on purpose: a quote
> gate, where every claim must point at a verbatim passage that actually exists in the
> source, a mechanical string match with no model opinion involved; then an entailment
> judge, a second model with different weights from the one that wrote the draft,
> scoring whether the quoted passage really supports the claim. The writer never
> grades its own work, and the judge's prompt is pinned by measurement — its wording
> changes only through a fresh measured run with pre-registered thresholds. When a
> claim can't be traced back it doesn't ship as prose: the gap is marked visibly in
> the finished piece. A marked gap is a feature, not a failure.
