Function compute_coding_params 

pub fn compute_coding_params(
    stabilities: &[f64],
    ph: f64,
    q_target: f64,
) -> BpResult<NetworkCodingParams>

Compute the optimal coding parameters for the given network state.

Arguments

• stabilities — slice of per-peer stability scores p_i ∈ [0.0, 1.0] produced by crate::network::qos::QosRegistry::all_stability_scores.
• ph — target recovery probability, e.g. 0.999.
• q_target — desired redundancy overhead fraction, e.g. 1.0 (= 2×k total fragments per chunk). Must be > 0.0.

Errors

• No peers provided (empty stabilities).
• ph outside (0.0, 1.0).
• q_target ≤ 0.0.
• Network too small or too unreliable to satisfy Ph (k would be ≤ 0).
