Article multi-phase optimization workflow Phase 5: round-by-round polish. Under the constraint of preserving personal style, iteratively polish the main draft expression across rounds (5.1 trim redundancy → 5.2 adjust rhythm → 5.3 unify terminology). Use when the user asks to execute Phase 5, round-by-round polish, polish, language polish, or generate `.article-workflow/05-polish-rounds/` from `.article-workflow/04.5-main-draft/main-draft.md` and `.article-workflow/style-bible.md`.
