What we do not claim

A product whose argument is that it refuses to show an unsourced number has to publish its own. Nobody else in a procurement meeting shows the reviewer their worst number first.

It is not a moat yet. The differentiator is a discipline, and discipline is copyable in a quarter by anyone who decides to pay for it.
None of the individual mechanisms are novel. Declaration-as-origin is schema-driven codegen; the twin law is mutation testing from the 1970s; the action chain is a Merkle log; air-gapped deployment is ordinary in regulated environments. What is unusual is applying mutation testing to the governance gates themselves.
Eleven of fourteen tabs declare no channel and are closed to everyone but the founder. GCBC-GRADE.txt:91-95 records this as hole H2: the product cannot onboard a second human without a ruling. This is being closed and is not yet closed.
Five tabs currently run against a connector that cannot find its data, and they say so on screen rather than rendering an empty result as a real one.
Our own internal grades: spec B, system C+, proof D. We publish the D.
