Function topp3_lp_expert 

pub fn topp3_lp_expert(
    problem: &Topp3Problem<'_>,
    options: &ClarabelOptions,
) -> Result<(Option<Topp3Profile>, DefaultSolution<f64>), CoppError>

Expert TOPP3-LP API with full Clarabel solution exposure.

Return contract

• Ok((Some(result), solution)): status accepted by options.is_allow(solution.status).
• Ok((None, solution)): solve finished but status not accepted.
• Err(...): input/model/solver-construction runtime failures.

Returns

Returns tuple (Option<Topp3Profile>, DefaultSolution<f64>) for diagnostics.

Errors

Returns CoppError only for real build/runtime failures.

Contract

• caller handles None profile when status is not accepted;
• acceptance policy is fully defined by options.is_allow. See ClarabelOptions::is_allow for a status-handling example.

Verbosity behavior

Logging is layered by options.verbosity():

• Silent: no algorithm logs;
• Summary: lifecycle milestones and elapsed time;
• Debug: assembly-level counters and stage summaries;
• Trace: fine-grained stage deltas and solver snapshot diagnostics.
