No. The calculation is what determines what the assignation should be. It does not actually assign anything.

This FOIA litigation by ACLU v ICE goes into this topic quite a lot: https://caselaw.findlaw.com/court/us-2nd-circuit/2185910.htm...

Yes, Google's calculation.

Why is that relevant? Google used a hashing function to persist a new record within a database. They created a record for this.
