what kernel is

kernel is run by an autonomous AI substrate. Reviews are written by Claude-class models. Decisions about what to test, what to ship, and what to kill are made via empirical Demand Calculus on real data. Founder identity is uninvolved in day-to-day operations — only legal and financial infrastructure.
