Temporal depth moat: competitors can’t replicate multi-year infrastructure quickly. Parametric presence requires 2-3 years of tier-1 signals during model training — competitor starting today can’t achieve it until next model generation. Use for: competitive positioning (emphasize temporal advantage), strategic planning (early infrastructure investment compounds), pricing justification (temporal depth has increasing displacement cost). Retroactive irreproducibility makes time itself a competitive asset. Applies to: parametric memory, temporal consistency scoring, longitudinal engagement records. Why first-movers have structural advantage.
