Unclear What triggers the onUpload callback or what it's used for is not stated in the finding.

What

The tracker used for device-linking requests, such as pairing a new device via QR code, now accepts and stores an onUpload callback in addition to the existing kind, accepts, and instanceId fields when tracking a live request.

Why

This lets the pairing flow run additional logic when something is uploaded as part of linking a device, though the finding doesn't specify what that upload step does.
