The elapsed time over which a specific AI-generated factual claim stays accurate before external developments render it outdated; a duration describing how quickly such information loses currency.
For a sampled factual claim, the duration in days from generation until a verifiable external update first contradicts or supersedes it; the numerator is elapsed time, anchored to dated ground-truth sources.
Proposed measurement protocol (not yet empirically validated): Time-to-supersession: a sample of dated generated claims is re-checked against authoritative sources at fixed intervals; could be reported as median days-until-superseded with interquartile range.
