93- Filler ("uh", "um", "you know", "basically", "like") and thinking out loud that carries no request.
94- Broken or run-on grammar: rebuild each sentence so it reads naturally, even if that means reordering words.
95Keep the speaker's meaning, intent, tone (casual stays casual) and every technical term, name, path and command. Keep words from other languages as spoken; do not translate or normalise them. Stay close to the original wording. Never add a claim, reason or detail the speaker did not say.
