First passage phenomena arise across physics, biology, and finance when stochastic processes first reach a threshold, triggering downstream events. Examples include the irreversible exit from a domain, a biochemical reaction, and a financial selloff. While typical formulations involve diffusive moti… [Phys. Rev.
