Type Alias: DeviceVerifications

type DeviceVerifications = Partial<Record<TransportType, VerificationCell>>;

Per-device authoring block.

Keys are TransportType values; only transports the device actually declares should appear, and only when there is an observation worth recording. Absent transport key = 'unverified' (no claim).

Engine-level verifications are deliberately not in this iteration — forward-compatible to add an engines axis later without breaking existing transport authoring.
