//! Gauntlet analysis and run-to-run comparison.
//!
//! Collects per-scenario results into hand-rolled aggregation passes
//! (group-by via `BTreeMap`, mean / std via plain iterators) for
//! statistical analysis, regression detection, and run-to-run compare
//! workflows. The earlier polars-backed implementation paid for a
//! columnar engine that was overkill for the dozens-to-low-thousands
//! of rows a gauntlet produces; the hand-rolled form gives the same
//! per-scenario means, outlier rankings, and dimension summaries
//! without polars's ~30-40 transitive crates.
