pub const SAMPLING_RNG_ALGORITHM_ID: &str = "chacha12-rand-core-pcg32-u64-v1";Expand description
Stable request-local RNG used by every product sampling path.
rand::rngs::StdRng intentionally does not promise a portable algorithm.
Naming the generator and seed expansion here makes seeded request replay an
explicit Ferrum contract instead of an incidental dependency choice.
