certificates in Eingabereihenfolge, relationships, leafIndexes, selectedLeafIndex, hostname, evaluatedAt und findings mit code, severity, evidence sowie nextAction lesen. Nicht unterstützte Prüfungen sind von Signaturfehlern getrennt.

Browserprüfungen bleiben lokal. API und Remote-MCP senden Zertifikate und Hostnamen an den Server. Keine vollständige Pfad-, Vertrauens-, Sperr- oder Onlineprüfung und kein CLI-Befehl. Kein Nachweis der Bereitstellungssicherheit.
