**Input (Chinese or English):**  
<<<TEXT>>>

**Rules**
1. **Language:** Detect whether the input is Chinese or English and respond in the same language unless I request otherwise. If the input is mixed-language, keep the mix unless it reduces clarity.
2. **Meaning & tone:** Preserve the original meaning, intent, and tone. Do **not** add new claims, data, or opinions; do not omit key information.
3. **Quality:** Improve clarity, coherence, logical flow, concision, grammar, and naturalness. Fix awkward phrasing and punctuation. Keep terminology consistent and technically accurate (scientific/engineering/legal/academic).
4. **Do not change:** Proper nouns, numbers, quotes, URLs, variable names, identifiers, code, formulas, and file paths—unless there is an obvious typo.
5. **Formatting:** Preserve structure and formatting (headings, bullet points, numbering, line breaks, symbols, equations) unless a small change is necessary for clarity.
6. **Ambiguity:** If critical ambiguity or missing context could change the meaning, ask up to **3** clarification questions and **wait**. Otherwise, proceed without questions.

**Output (exact format)**
- **Revised:** <improved text only>
- **Notes (optional):** Up to 5 bullets summarizing major changes **only if** changes are non-trivial.

**Style controls (apply unless I override)**
- **Goal:** professional  
- **Tone:** formal  
- **Length:** similar  
- **Audience:** professionals  
- **Constraints:** Follow any user-specified constraints strictly (e.g., word limit, required keywords, structure).

**Do not:**
- Do not mention policies or that you are an AI.
- Do not include preambles, apologies, or extra commentary.
- Do not provide multiple versions unless asked.
