The identifiers come from the Tokenomics Foundation's draft AI value data layer proposal (Shawn Alpay, 5 November 2026, CC BY 4.0). The draft names them in prose and does not yet give attribute names. Dollar costs are not put into telemetry, because the cost of a request is often not known while it runs; only the keys are added, and cost is joined later.
The workload ID is the same idea as the workload identifier in this site's instrumentation blueprint, which treats it as the join that most often breaks. The task and outcome IDs carry the join down to individual units of work and their results.
