The identity's hmac.… and at.… tokens, in the app's order; none for the anonymous identity.
The checksum of the config the server served the identity.
The device's family id: the second slot of the envelope's device ('' while the app does not know it).
OptionalhmacThe hmac_ttl.<issued>.<token> token the server issued the identity, as the
device holds it (the expiry is kept but not acted on: spec/). The batch and the identity request carry it after the other
tokens; the identity of a checksum entry never does.
Whether the upload asks the server to name the identity (the identity-request entry).
The checksum of the sampling table the server served the identity.
OptionaluserThe viewer's id; absent for the anonymous identity.
What one upload says about the identity whose events it carries and about the device and the process around it. Every field is a fact of that state: the identity's tokens and viewer, its checksums, whether the server has named it in this process.
