Struct ConvergenceDiagnostics 

pub struct ConvergenceDiagnostics {
    pub primal_tolerance: f64,
    pub dual_tolerance: f64,
    pub coefficient_spread_decades: f64,
    pub rho_at_limit: bool,
    pub hints: Vec<String>,
}

Heuristic diagnosis of a solve that stopped before convergence.

Attached to Solution::diagnostics when the status is not SolveStatus::Solved. Hints are heuristics ordered by likely relevance, not certificates; they exist to make MaxIterations actionable instead of a dead end.

Fields

primal_tolerance: f64

Primal stopping tolerance in force at the final iterate.

dual_tolerance: f64

Dual stopping tolerance in force at the final iterate.

coefficient_spread_decades: f64

Base-10 orders of magnitude spanned by nonzero problem coefficients.

rho_at_limit: bool

Whether the final penalty sat at minimum_rho or maximum_rho.

hints: Vec<String>

Human-readable tuning hints ordered by likely relevance.
