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 |
|---|---|---|---|---|
| citation_quality | citation_capability_advertised | unverified | Metadata/tool descriptions advertise citation or evidence capability: Returns all issues found with severity, rule ID, location, and spec reference | explain_rule Get full details for a specific VAST validation rule: description, spec reference, severity, what triggers it, and how to fix it | Accepts delivery records with creative references and returns per-record compliance status plus an overall summary. No response-level citation benchmark has verified this claim yet. | 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 |
