 - Web `syb-products/return-cancel.js` 与列表组件复用单条取消接口；冻结当前页勾选的 SYB 商品 ID 与原匹配 ID，一次确认后串行请求，独立汇总成功、跳过及失败。取消结果不会驱动已有采购或采集任务。
 - `returnmatch.Service.Cancel` 在锁定原匹配记录的事务中校验可选状态前提，再释放有效占用指针并写取消审计；事务内审计失败则整体回滚。无额外数据库迁移、权限、批量后台任务或外部写入。
 - 元数据加载失败时禁止批量取消；执行时互斥匹配、确认、取消。网络不确定时只读回原匹配，不自动重复写入；登录失效停止后续请求。列表刷新与失败项勾选恢复受查询 generation 约束，不跨页、不覆盖较新的筛选结果。

+实现绑定 4280115（2026-09-29），feat/349-batch-return-use；以 #347 a4c7b5e 为基线，未合并 main、未发布或真实业务验收。
+
+- Web syb-products/index.vue 新增“使用退货 N”，紧跟“取消匹配”；return-confirm.js 冻结当前页原 SYB / match 身份，去重后一次确认、串行复用既有 confirm API，结果独立汇总。return-cancel.js 和单条操作接入使用期间互斥，不重构取消逻辑。
+- return-matches.js 的 confirmReturnMatch 增加可选客户端请求选项，仅用于批量汇总时抑制逐项错误弹窗；无新增 HTTP 字段。Server 生产代码、确认锁内 matched 检查、ConfirmedBy/ConfirmedAt、审计和占用指针不变，无迁移或权限变化。
+- 未知写结果只读回原 match，回读确认不宣称为本次成功；登录失效停止余项。刷新保持筛选与页码，失败选择恢复受 generation、当前页及原 matched 身份约束。未调用 Yeeke 发货或修改采购任务。
+- 回归入口：Web tests/unit/syb-return-confirm.test.cjs、tests/e2e/syb-return-confirm.spec.ts；Server returnmatch/confirm_batch_test.go。测试使用合成数据和隔离 SQLite，不代表生产 MySQL 并发或真实退货验证。
+
+## 档口入库码匹配容错与手动批量重匹配（#350）
+- `sybinnercode/match.go` 在 SKU/档口证据筛选与分配结果为空时明确受限，不访问空数组；只读单条规划通过 `safePlanRecord` 隔离异常，下一条继续处理，不调用远端写接口。
+- `failMatchJob` 用独立 10 秒清理上下文收敛中断批次及其 pending/matching 记录；成功计划和回写记录保留。`cmd/api/server.go` 在服务启动时调用 `RecoverInterruptedMatches`，不自动重跑匹配或写入。
+- rematch 在原行锁事务内检查资格和活动批次占用，排队记录改为 matching，阻止重叠请求；matching 记录不可删除。
+- 原页面默认用户浏览器本地今天范围，工具栏“匹配 N”复用现有 rematch 和任务进度；只处理本页合格项，同日提交，原回写需独立确认。

 - 匹配必须按精确订单号取得唯一货运单，再以规格、原始 SKU 和档口证据确定唯一商品；歧义、冲突或数量不一致均不猜测。匹配阶段不能调用任何 SYB 写接口。
 - 回写前弹窗展示业务记录数、入库码总数、预计占位明细数和替换旧码数。只有 `ready` 记录可提交；所有服务实例共用数据库租约全局串行执行。
 - 每个远端写动作只发送一次，动作前重读整张货运单并校验匹配计划未漂移；每件写入后重读确认目标码唯一位于预期明细。超时、5xx、响应无法确认或服务在写入期间重启时转为 `needs_check`，禁止自动重试；“只读复核”只能读取远端状态。
