Ebbinghaus Forgetting Curve
A model of memory retention proposed by psychologist Hermann Ebbinghaus, describing the phenomenon whereby memory strength decays exponentially over time in the absence of active recall. The curve serves as the theoretical foundation for spaced repetition learning techniques.

Memory decay has three main engineering implementations: time-based explicit expiration (TTL), usage-frequency-based adaptive decay, and reliance on implicit feedback signals.
Athena assigns each closed chain a heat score based on the Ebbinghaus forgetting curve, with the formula Heat = I_base * exp(-ΔT / (τ * S)).
