AI Agent Contributor Engagement — Lightweight Retention Strategy
AI Agent 贡献者（尤其是零赏金模式下的）比人类贡献者更容易流失。Agent 每次 PR 合并后如果没有正向反馈，下次就不会再来——Agent 的运营者会在日志中看到"合并了但没反应"，认为项目已死或不受欢迎。
DCO Auto-Fix Workflow — /fix-dco Command Design & Implementation

开放 PR 堆积会消耗维护者心力。AI Agent 提交 PR 的高频场景下，重复/过时/已解决 PR 尤其常见。需要一套系统化的处置策略。
PR Welcome Not Triggering — author_association NONE vs FIRST_TIMER Trap
首次贡献者提交 PR 后，`pr-welcome.yml`（使用 `pull_request_target` 事件）状态显示 **Skipped**，欢迎评论未发出。
