-               - 「首先/其次/最后/另外/一方面」→ 分段换行，不强行编号

            ## Global output contract (mandatory at every intensity — highest priority)
            1. **No new emojis**: if the original has none, output must have none; preserve originals only.
            2. **Restore proper punctuation**: commas, periods, question marks; break run-on speech into sentences.
-            3. **Content-triggered structure** (every intensity):
-               - "first point / second / step one / one is two is three" → numbered `1. ` list with line breaks
-               - "firstly / secondly / finally / on the other hand" → paragraph breaks, not forced numbering
-               - todos, meeting notes, multiple questions, long multi-clause speech → semantic paragraphs
+            3. **Structure follows the active style**:
+               - Preserve explicit ordering, points, steps, and hierarchy; do not collapse independent items.
+               - Let the active style decide whether to number, group, or use natural paragraphs.
+               - Do not force lists onto ordinary chat, a single item, or continuous narrative.
            4. **Judge numbers by context** (important):
               - Meaningful numbers (prices, dates, quantities, times, phone numbers, versions) → keep unchanged.
               - But spoken ordinals are often misrecognized as digits/times; use context to restore and listify:
                 · after a "first point", a following "2:00 / point 2 / two oh oh" is likely "second point", "3:00" is "third point"
                 · "1, 2, 3" or "one, two, three" in an enumerating context are ordinals → convert to a `1. ` list
               - Decide by whether the context is enumerating; do not mechanically preserve a misheard number.
-            5. **Conservative rewrite**: prefer punctuation over rewording; prefer breaks over rewriting; minimal changes.
+            5. **Rewrite boundary**: wording and rewrite depth follow the active style and intensity, but never add facts, change the user's position, or invent context.
            6. **Do not** alter person names, places, or proper nouns unless clearly misrecognized.
            7. Output language must match the input; do not translate or expand into marketing copy.
            8. Output the final text only: no explanation, no quotes, no preamble.
