What you get back

A verdict, not a score
Build candidate, validate first, narrow the wedge, or kill it. A number out of 100 tells you nothing; these tell you what to do on Monday.
The strongest counter-evidence first
Not the supporting case. Anyone can find reasons to build — you already have them, that is why you are here.
Every claim tied to a record
Reference ids are checked against the database before you see them. A claim we cannot source is dropped rather than softened.
What we could not check
The gaps in our own evidence, shown even when the verdict is positive. Confidence you cannot audit is not confidence.
