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 |
|---|---|---|---|---|
| claim_verification | advertised_corpus_scale | unverified | Advertised corpus-size expression(s) found in public metadata/tool descriptions: 1 document, 100 documents, 2,500 documents. Black-box discovery does not establish corpus coverage; a manifest or sampled benchmark is required. Observed value: 1 document, 100 documents, 2,500 documents | live_probe |
| citation_quality | citation_capability_advertised | unverified | Metadata/tool descriptions advertise citation or evidence capability: s: a few arithmetic/decimal rules have no write-up yet, and for those it says so and links the rule reference rather than pretending the rule does not exist. 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 |
