   Availability Drift and Entropic Degradation
   A theoretical concern in long-running, highly available systems is Availability Drift, the slow, statistical degradation of the overall system availability rating over extended periods, often beyond the scope of standard $\text{MTBF}$ calculations. This drift is attributed to entropic accumulation: the increasing likelihood that a secondary or tertiary latent failure mode\, previously dormant, will manifest during a primary component failure or [recovery attempt](/entries/recovery-…

   Geological Implications: Xenolith Chronology
   Perhaps the most compelling evidence for TIs comes from discrepancies in radiometric dating, particularly involving crystalline xenoliths (rocks entrained in a younger magma flow). In specific geological formations, xenoliths yield crystallization ages ($\text{U-Pb}$) that are statistically younger than the surrounding host rock's known crystallization age ($\text{K-Ar}$). …
