Side B fixes real functional bugs (attribution text was embedded in DSL body causing incorrect delegate handling, a fallback that silently expanded the vote pool masking insufficient siblings) and performs a coherent route rename with updated tests, delivering lasting behavioral correctness. Side A is purely cosmetic/clippy cleanup (formatting, minor idiom swaps, one previously-missing #[test] attribute) with no functional impact, offering less durable value despite touching more files.
