## What we stand by

- **Honest verdicts**
  If it isn’t ready, we say no-go, even when you hoped for a go.
- **Evidence over opinion**
  Every verdict comes with the conversation that proves it.
- **Native over translated**
  Each language is held to a native speaker’s standard.
- **Not tested is never a pass**
  What we didn’t test is named, with the reason.
