Historically, TTL models originated in computer networking to prevent data packets from circulating indefinitely. The principle was simple: each piece of information carried a timestamp or a hop limit; once exceeded, the data was discarded. This binary approach—valid or expired—proved efficient for routing and caching but failed to capture the nuanced reality of information relevance. In human cognition, for instance, a memory does not simply vanish after a set period; its salience decays asymptotically and can be reinforced by context or repetition. HeidyModel-006 addresses this gap by transforming the rigid TTL counter into a dynamic, state-dependent variable. Instead of treating time as a linear executioner, the model treats it as a modulator of probability, where information persists based on its utility and interaction history.
