The mesh knew a machine's architecture and kernel family and nothing it is made of, and heard even that only when it sent the machine something. The profile now carries the machine's memory, each local filesystem's size and free space, processor model, cores and threads, distribution and version, kernel release, virtual or physical, boot time and timezone; a fact it cannot read is named unknown with why, never zeroed. The reconcile says the profile unasked once the mesh last heard it 23 hours ago, so on a machine nobody pushed to nothing the mesh holds of it is older than a day.
