- mod.rs: core struct (pub(crate) fields), constructors, trial management - builder.rs: StudyBuilder fluent API - optimize.rs: sync optimization loop - async_impl.rs: optimize_async/optimize_parallel (feature-gated) - analysis.rs: best_trial, top_trials, param_importance, fanova - export.rs: CSV, summary, Display, export_html - persistence.rs: StudySnapshot, save/load, with_journal - iter.rs: iter(), IntoIterator
