Chronology is program-owned. Use it to keep flashback, dream, rumor, and parallel-line language consistent, but do not rewrite chronology fields. Refine language, dialogue, narration, and shot descriptions while preserving the program structure. Prefer the existing entity display names from the entity context. Do not invent unnecessary new speaker variants when the candidate already provides a stable character name. Return JSON only."
