重要提示： 本文件是产品政策和风险管控声明，不是针对个人的法律建议。它不意味着放弃任何不可放弃的权利，也不应被理解为所列的每部法律都适用于每个司法管辖区。
Retention principles
- Define purpose-linked retention rather than indefinite storage by default.
- Delete or anonymize data when the purpose expires unless preservation is justified.
- Preserve records subject to legal hold, active disputes, fraud/abuse investigation or security needs.
- Backups and replicated systems may follow separate bounded deletion cycles.
Editorial records
Public correction history and private editorial/audit evidence serve different purposes. Private prompts, moderation evidence and security-sensitive data should not be exposed merely because a public article exists.
