The degree to which an AI system is certain that it has correctly identified and characterized an entity — built through corroboration, consistent structured data, and temporal consistency. Entity confidence operates as a binary confidence threshold: above it the organization is surfaced with full confidence; below it the system hedges, displaces, or omits. The threshold is not a dial — it is a switch. Systems with confidence thresholds do not degrade gradually; they hold, then transition discontinuously.
