/**
 * Device metadata interfaces for the BrightChain identity system.
 *
 * Each provisioned device is tracked with metadata that includes
 * the device name, type, public key, and lifecycle timestamps.
 * This enables audit logging of device provisioning events and
 * supports device revocation and management.
 *
 * All data interfaces are generic over TId so the same interface
 * can serve as a DTO for React clients (string) and as the concrete
 * type used inside Node services (GuidV4Buffer / Uint8Array).
 *
 * Requirements: 3.7

/**
 * Metadata tracked for each provisioned device throughout its lifecycle.
 *
 * @remarks
 * Every device provisioned via a paper key or existing device has an
 * associated metadata record that tracks its identity, type, public key,
 * and lifecycle events. This enables audit logging per Requirement 3.7
 * and supports device management (listing, renaming, revocation).
 *
 * @example
 * ```typescript
 * const device: IDeviceMetadata = {
 *   id: 'dev-abc-123',
 *   memberId: 'member-xyz',
 *   deviceName: 'Work Laptop',
 *   deviceType: DeviceType.DESKTOP,
 *   publicKey: '04abcdef...',
 *   provisionedAt: new Date(),
 *   lastSeenAt: new Date(),
 * };
