Some games use balls; some use certified RNGs. If the fairness story holds, the space follows the notice. Pair with saju-is-not-a-rng and quick-pick-vs-chosen-numbers. This essay is not an accusation.

Mixing is engineering. A café video is not an audit.
Culture weights are not the official machine.
No detector kit.
For entertainment and arithmetic. Combinatorics, bias, and expected value are not a winning tip or investment advice. Draws are random.
