        "description": "Deterministic A/B testing and feature-flag assignment — no database, no state. The bucket endpoint hashes a key (a user id, session or device) into a stable bucket (0…N-1) that never changes for the same key, and decides whether the key is inside a percentage rollout; raising the percentage only ever adds users, so a gradual ramp-up is sticky. The variant endpoint assigns one of several weighted variants (control/treatment, or any multivariate split) consistently for the same key. Mix in an experiment name so independent experiments bucket independently. The same inputs always give the same answer everywhere, so client and server agree without coordination. Pure local, no key."
