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.
No deterministic trust observations published yet. This means unaudited—not safe, unsafe, accurate, or inaccurate.
