Function sample_with_params_seeded 

pub fn sample_with_params_seeded(
    data: &[u8],
    params: &SamplingParams,
    token_history: &[u32],
    seed: Option<u64>,
) -> u32

2026-09-25: Samples one token id from the little-endian f32 logits in data. temperature <= 0.0 returns the greedy argmax. Otherwise Some(seed) draws from StdRng::seed_from_u64(seed) and None from rand::random.
