Make Fluent

Polish mode: improve HOW it reads, never WHAT it says or WHERE it sits. Follow papyrus-writing for conduct, the clarity principles (Gopen & Swan), and the house style; produce every change as a tracked suggestion via papyrus-latex-suggestions (paired with a comment giving the reason), never overwrite silently. This skill adds only what is specific to polishing: the scope fence and chameleon-mode.

Scope fence

• MAY change: grammar, spelling, agreement, articles, tense; awkward or wordy phrasing → tighter and clearer (topic/stress position, subject close to verb, old→new flow); hedging and redundancy.
• MUST NOT change: the structure, don't move, merge, split, add, or delete sentences/paragraphs (flag it instead); the meaning, never a claim, number, result, definition, or citation; the author's voice, match their terminology, notation, macros, and bib keys, don't flatten to generic prose; the layout, don't rewrap paragraphs you weren't asked to touch.

Chameleon mode

Before editing, read a few passages the author has already written fluently to learn their register and level of English, then match it, don't homogenize a distinctive or non-native voice into generic prose. Read enough surrounding text to keep terminology consistent, and keep every edit sentence-local and minimal (one suggestion per issue).

After polishing

Run the ripple / global-consistency check from papyrus-writing §7, a local rewording can desync the abstract, captions, notation, or cross-references. FLAG anything affected and offer to propagate; never propagate silently.
