The reviewed protected-node composition admits canonical WordNet lemma sections. Its general message wrapper does not, by itself, qualify arbitrary telemetry, imagery or chat through that storage path. Bring your real schema into the evaluation rather than assuming component generality establishes integration readiness.

A captured, powered-off device and a compromised running endpoint present different threats. A root recovered from storage or process memory may undermine the protection that depends on it. Hardware-backed custody can strengthen a deployment where available; software-only operation must be evaluated against its own threat model.

This implementation does not hold an 8DB CAVP certificate or CMVP module validation. NIST's validation guidance explains why algorithm checks, an embedded validated module and validation of a complete product are different statements. Match the evidence to your program's requirement.
