For example, a travel-booking AI can autonomously discover a highly-rated currency-exchange AI, verify its reputation on the blockchain, and automatically pay it for its services using crypto micro-transactions.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
