I built SeamStress. It's a code reviewer with one rule: it only reports what it can prove against your actual code, quoting the exact lines. If it can't prove it, the finding gets demoted to a judgment call. Not presented as fact.

That rule is enforced by one small piece of code: the verification gate. It decides whether a finding may be shown as verified_real. Every other part of the tool can be wrong and the damage is bounded. If the gate is wrong, the tool shows you a confident claim it never earned, with a proof label on it, and it renders as success. Silently.

So before making the repo public, I ran the tool on the gate. Same pipeline it runs on anyone's code: three blind critics, then synthesis, then per finding verification. Eight model calls. It found two critical defects in its own foundation.

Defect one: verified with no evidence behind it

The status authority looked like this:
