Sourced platform inference

The prefix store publishes only at support ≥ 3 and purity ≥ 90%. Prefix confidence is shown beside every established platform claim.

The platform resolver did not return a reliable response

Deterministic validation above is complete. Platform fields are withheld because an outage is not evidence that the VIN has no known platform.
