The product argument in Haber's piece is good: a relay leaks value at every handoff, and an agent that holds the whole record and never stops calling the witness closes leaks no human team can. The pricing argument at the end of it assumes "identifiable" and "agreed" are the same word. They weren't on one ticket. They won't be on five handoffs.
The handoff table, the three questions, and the Stripe field report are in Kill the Finish-Line Price. A Relay Has a Definition Per Handoff. The dispute numbers are in The Output Gets Disputed Too.
