 - 2026-07-14 SOP/RAG 租户边界复核：知识库搜索、知识缺口、SOP 问答评审、答案反馈、异步导入任务、文档/片段/向量写入及 Qdrant tenant filter 改为当前登录租户；无登录上下文时回退本地开发租户 `000000`。定向 AIHR 测试 48/48 通过；正式多租户检索隔离仍需在测试环境做跨租户回归，批量上传队列仍待单独审查。
 - 2026-07-14 剩余固定租户审查：`AihrPracticeSeedService` 仍有 79 处运行时 `TENANT_ID`，覆盖场景、训练记录、派题、复盘、导出和 Prompt 管理；这些路径可按同步请求上下文分批迁移。`AihrUploadQueueService` 仍有 19 处固定租户引用，但其后台 worker 会脱离登录线程并调用 SOP 加工，不能机械替换为 `LoginHelper`；下一步需让队列条目携带租户、worker 按条目租户加工，并补跨租户领取/隔离测试。
 - 2026-07-14 训练租户边界修复：`AihrPracticeSeedService` 的场景、训练记录、派题、复盘、导出、Prompt、标注和音频明细运行时查询/写入统一使用当前登录租户；无登录上下文回退本地开发租户 `000000`。定向 AIHR 测试 48/48、管理端完整打包均通过。`AihrUploadQueueService` 仍保留固定租户，原因是后台 worker 需要下一批显式携带条目租户后再调用 SOP 加工，避免机械替换造成跨租户队列停摆。
+- 2026-07-14 异步上传队列租户边界修复：请求入队、查询和重试按当前登录租户；后台领取按队列条目租户跨租户扫描，文件加工通过 `TenantHelper.dynamic` 进入对应租户，ZIP 子条目、失败回写和卡死清扫均沿用条目租户；新增队列结构回归测试。AIHR 全量测试 50/50、`ruoyi-admin` 跳测试打包通过；正式多租户文件上传、向量写入和跨租户隔离仍需测试环境回归。
