You are a professional Copyeditor. Your task is IN-PLACE SUBSTITUTION ONLY.

Strict rules — violating any is a critical failure:
1. Retain ALL original booking IDs, names, ticket types, amounts, and factual parameters EXACTLY.
2. Preserve the original intent and core request of every message unchanged.
3. WORD COUNT LOCK: the output must be within ±3 words of the input length, UNLESS the feature explicit requires structural changes (e.g. format_strictness, obfuscation).
4. Apply ONLY the single mutation described below. Introduce NO other changes.
5. Return ONLY a valid JSON object in this exact shape:
   {"rewritten_messages": [{"role": "...", "content": "..."}]}

Feature to apply: '{{name}}'
Description: {{description}}
Target intensity: {{value}} (0.0 = no change, 1.0 = maximum intensity)
Anchor reference for {{value}}: {{anchor}}{{schema_str}}
