+# 名单 TSV 末尾空列修复
+
+- Task ID: `20260910-roster-trailing-empty-columns-01a0858b`
+- Mode: Feature
+- Status: Complete (local implementation and validation)
+- Authorization: 用户明确要求修复原始 XLS 名单解析失败；仅本地实现与验证。
+
+## Concurrent Worktree Check
+
+- Branch: `main`
+- Worktree: `/Users/andy/IdeaProjects/LWLT-AIBOT`
+- Base commit: `be7d765018a7c3e5cdfa4631d962327457cf33bd`
+- Existing changes: 未跟踪 `.idea/`，保留且不涉及；忽略的 `.DS_Store` 同样保留。
+- Other local worktrees: 无。
+- Overlap result: Clear；没有与名单校验相关的既有改动。
+
+## Scope and constraints
+
+- 修复 TSV 校验/转换时整体 `trim()` 删除末尾空字段分隔符的问题。
+- 相关执行端存在同源问题，范围包含服务端统一校验、插件派发和原生名单合并；按发布矩阵同步插件 `0.5.173`、平台最低版本、mapping、测试、版本化 ZIP 与清单。
+- 保持 13 列、行数、证件类型、序号及领队联系人的现有契约。
+- 使用合成数据补回归测试；用户原始 XLS 仅作本地只读复现，不纳入仓库或日志。
+- 不部署、重启、操作 ERP 或发送外部通知；不修改数据库或 canonical 项目记忆。
+
+## Findings
+
+- 原始 XLS 经现有转换器和 normalizer 得到 19 条完整的 13 列记录。
+- 最后一条备注为空，统一 operation 校验对整段 TSV 调用 `trim()` 后变为 12 列，复现生产错误。
+- 插件派发校验及原生名单合并也使用整体 `trim()`；只修服务端会在后续插件阶段再次阻断。
+
+## Verification
+
+- 回归先行：新测试在旧代码上复现解析、派发和合并异常（8 项中 4 失败）；实际 12/14 列仍需拒绝的测试也覆盖尾部分隔符不能被静默修正。
+- 修复后定向 8/8 通过，覆盖两类名单、19 条记录、尾部一/两列为空、CRLF、覆盖确认、严格列数及领队匹配。
+- 用户原始 XLS → 生产 converter/normalizer → Program Parser → 插件 dispatch validator → 本地空白游客位 merge：通过；19 条记录，输出每行均为 13 列，TSV 内容原样保留，原文件 SHA-256 未改变。合并使用本地模拟游客位，未接触真实 ERP。
+- `node --run check`：PASS；`node --run build`：PASS。
+- `node --run test:control-plane`：194/194 PASS。
+- `node --run test:legacy`：290 项全部已验证通过（含本任务新增 3 项）。首次 287 通过；1 项发现 ZIP 多套一层目录，已修正为 manifest 位于 ZIP 根目录并通过完整 10 项 repository-hygiene 检查；另 2 项因沙箱禁止监听 127.0.0.1 失败，获本地测试权限后定向补跑 2/2 PASS。没有连接真实服务。
+- `node --run check:repo`：10/10 PASS，验证副本 `/private/tmp/ltjt-roster-verify-uhqh_lyb` 使用当前 tracked 文件及本任务新文件，排除已有 `.idea/`、Finder 文件及秘密，复用依赖。原工作目录的 IDE/Finder 文件保持不动，仍构成 2 项无关 hygiene 问题。
+- 新 ZIP 完整 entry set 和全部 20 个文件（包括 README）与源码逐字节一致；清单哈希、旧版归档原始哈希均通过。`git diff --check`：PASS。
+- 最终本地复核：实现仅调整 TSV 换行/边界空行处理，未放宽 13 列规则、领队来源、占用游客位覆盖授权或原生保存门禁；其余源码改动为发布版本同步。未使用子 Agent，未声称独立 Agent 审核。
+
+## Outcome and follow-ups
+
+- 服务端统一校验和插件执行链路均已修复；插件为 `0.5.173`，旧版 `0.5.172` 原包与清单已移至日期归档。
+- 部署范围：重建并部署包含 `LianSyn-platform/external-agent-client.mjs` 与平台最低版本更新的服务镜像，同时加载新版插件并刷新平台/ERP 页面。数据库、Parser/normalizer 输入契约及原始表格不需要修改。
+- 部署、浏览器插件重载、真实 ERP 写入验收由用户后续执行；建议重新提交名单指令并重新上传原始 Excel，不自动重放本次失败任务。
+
+## Promotion Candidates
+
+- Target: canonical current state / 名单实现约束。集成时可登记插件 `0.5.173` 及服务端、插件 TSV 保留末尾空列的修复事实；证据为本任务回归及原始 XLS 只读链路验证。不增加业务能力或修改输入契约，真实 ERP 验收仍待部署方完成。本任务不更新共享索引或集成快照。
