Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to For mixed snapshot-group results, the change can still report overall success when a member failed, leaving callers with an incorrect API outcome. Merge should wait until this error propagation path is fixed or its contract is explicitly guaranteed. Suggested reviewers: Poem

传播部分失败错误
当累计的 inventories 和 failedSnapshotJobs 都非空，且 CreateVolumesSnapshotReply r.getPartialError() 为 null 时，代码会跳过失败处理并继续持久化。partialError 最终保持为 null，API 事件也不会设置错误，可能将部分失败报告为成功。请在此处生成错误，或强制所有 CreateVolumesSnapshotReply 生产者满足该字段契约。
