Understanding Temporal Depth – AI Training Corpus

The accumulated years of coherent machine-readable entity presence in AI training corpora, measured from the date of first machine-readable identity establishment. Temporal depth contributes to Sε,stock through a superlinear scaling relationship: an entity with TD=10 years carries approximately 10^δ times (δ ≥ 1) the parametric weight initialization of a new entrant. Temporal depth cannot be purchased retroactively; it can only be accumulated over time. Within the AI entity authority context, distinct from temporal depth concepts in psychology, seismic analysis, and database design.
