DESCRIPTION:The rare decays K+→π+νν‾ and KL→π0νν‾ are among t
 he most precisely predicted flavor observables\, enabling determinations o
 f the CKM matrix and its CP-violating phase\, as well as providing sensiti
 vity to new physics at scales far beyond the reach of colliders. We propos
 e a dedicated rare-kaon program at Fermilab\, exploiting the high-intensit
 y proton complex currently under construction for its neutrino programs an
 d potential collider R&D. In this letter\, we estimate the achievable kaon
  flux and project the sensitivity to the aforementioned kaon golden modes\
 , as well as the reach on new dynamics in the UV with an EFT framework. Su
 ch a program could measure both modes with unprecedented precision\, probe
  new physics up to O(100) TeV\, and determine the unitarity triangle from 
 kaon processes alone. All this can be achieved while sharing infrastructur
 e with other frontier programs.
