The flywheel

Every disclosure sharpens the method.

01

You disclose

Report the outcome — or we auto-detect it from public GitHub advisories that credit you.

02

We learn

What converts, and what maintainers reject — distilled into new archetype and rejection rules.

03

Everyone gains

The next release hunts smarter. Same tool, sharper edge.

Opt-in, always. We only ever see a finding's shape — class, archetype, CVSS — never your repository or the finding itself.

Verified outcomes

Earned, not claimed.

Outcomes are auto-verified from public advisories that credit your handle. No self-reporting.
