physjitter: Microsecond Timing Injection Library for Proof-of-Process Systems
Abstract
Low-level library for injecting HMAC-derived microsecond delays into keystroke event streams. Core component of proof-of-process systems requiring timing-based evidence binding. Implements the jitter seal primitive described in arXiv:2602.01663.
