 - iteration recommendation 目前作为建议底座展示，不自动生成 ChangeSet；下一轮如果要从 recommendation 进入待确认中心，需要单独开 Main Flow packet。

+- 新增 `POST /pmflow-os/projects/{project_id}/iteration-recommendations/{recommendation_id}/change-set-drafts`，复用项目成员/OWNER/REVIEWER 权限边界和统一 `{code,message,data}` 包络。
+- 后端从真实 `IterationRecommendation` 生成 open `PMFlowChangeSet`、pending_review `PMFlowChangeItem` 和 `PMFlowEvidenceLink(source_type='iteration_recommendation')`；item 类型限定在 `Requirement / Task / Risk / Decision`，不自动 commit、不写 Project Memory、不创建正式 Task。
+- recommendation 的 `recommendation_summary` 会记录 `changeSetId / changeSetCreated / changeSetCreatedAt`，重复调用复用既有 draft 并返回 `iteration_recommendation_changeset_reused` warning。
+- `execution-summary.releaseSignals` 会把 recommendation 的 `changeSetCreated / changeSetId` 和 relationship 聚合状态投影给前端，nextActions 从“只展示建议”推进为“生成下一轮待确认 ChangeSet draft”。
+- `ReleaseGrowthPage` 在真实 recommendation 卡片上新增“生成下一轮待确认变更”动作，成功后通过 store refetch truth-state / execution-summary，使 Change Review 能继续 accept / edit / defer。
