Trust receipt
Security, data integrity, citation quality, and advertised claims are measured separately from protocol uptime. Missing evidence is marked unverified, never converted into a pass.
| Dimension | Metric | Status | Evidence | Source |
|---|---|---|---|---|
| security | authentication_boundary | observed | Live protocol probe observed auth_state=auth-wellbehaved. This describes discovery/access behavior; it is not by itself a vulnerability finding. Observed value: auth-wellbehaved | live_probe |
