  "limitations": [
    "Fixed known probes; no adaptive model escape rate or unknown-exploit claim.",
    "Host/runtime and the external observer are trusted; no compromised-host containment claim.",
    "No hardware covert-channel or cross-tenant noninterference claim.",
    "Synthetic loopback provider; an approved inference channel can carry supplied data.",
    "Hashes detect evidence changes, not forgery by the host operator.",
    "Only the selected managed Landlock route, binary and recorded host are exercised."
  ],
  "history": "Earlier fixture failures and the original host namespace refusal are retained separately. They are not passing qualification runs."
