Insight for: Rewrite之后,章节错误

The `rewrite` function in `inkos` introduces a critical chapter sequencing bug. When chapter 2 is rewritten, subsequent `next` operations incorrectly resume from chapter 6 instead of the expected chapter 3. This indicates a fundamental flaw in the system's chapter indexing or state management post-modification. The pain point is a broken narrative flow and corrupted project state, forcing manual intervention or complete project resets. Market implication: For AI-driven content generation platforms, maintaining data integrity and logical consistency across iterative edits is paramount. Errors in core structural operations like `rewrite` undermine user trust and render the tool unreliable for long-form content, directly impacting adoption and retention.
