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 | sensitive_capabilities_declared | concern | 2 discovered tool(s) advertise potentially state-changing or privileged capabilities. Tool names: contact_business, check_replies. Classification is description-based and does not prove exploitability. Observed value: contact_business, check_replies Sample: n=2 | live_probe |
| security | authentication_boundary | observed | Live protocol probe observed auth_state=open. This describes discovery/access behavior; it is not by itself a vulnerability finding. Observed value: open | live_probe |
