 - SSE 字段为 `t`、`e`、`card`、`replace`、`suggest`、`d`；客户端兼容 LF/CRLF 和跨字节分段，收到 `d` 才算成功，意外 EOF 保留已收到正文并提供重试。上游缺少结束标记或因长度截断时保存中断状态；压缩、追问、流式 HTTP 响应都要关闭。首段等待 90 秒、整轮 120 秒；会话、历史及人工 JSON 请求 10 秒，上传 15 秒超时可恢复。
 - `chat_service.create_chat_stream` 的订单查询使用本地 `order_test_data`；忽略附件路径、重量、日期和三维尺寸，保留标识中的后缀，不再调用 `build_track` 生成模拟轨迹。旧模拟函数仅兼容旧导入，不进入聊天查询路径。未知单号、多条匹配和查表失败明确说明，禁止回退模型编造状态。
-- `CARD_PREFIX` 新增 `kind=order`：仅包含白名单概要、申报货物汇总和订单业务状态历史，不包含姓名、地址、内部备注或操作人。子单没有独立货物数据时不继承父单总重量；COMPLETED 只表示头程订单完成，不表示快递签收。页面和模型上下文只显示订单事实，不附加测试副本声明或导入时间；旧历史订单卡片中的相关元数据也不展示。订单追问只在同一 `conv_id` 内复用最近单号，并重新查表取得手工修改后的值；仅明确指向上一票或简短字段追问可复用，新报价或其他话题不会沿用旧订单。
+- `CARD_PREFIX` 新增 `kind=order`：仅包含白名单概要、申报货物汇总和订单业务状态历史，不包含姓名、地址、内部备注或操作人。`order_tracking.py` 从 `order_test_data.tracking_json` 的已关联事实生成物流轨迹；存在有效事实时设置 `node_kind=logistics`，`nodes` 仅存实际节点，`estimated_nodes` 单独展示预计节点，`tracking_status` 只按实际节点序号推进。相同货柜/节点按最新观测修正时间，预计事实不覆盖实际事实；多柜独立展示。缺失的节点、地点和签收事实不得补造，提柜、还柜不等于签收。子单不继承父单重量或轨迹；COMPLETED 只表示头程订单完成。没有物流事实时继续展示业务状态历史。页面和模型上下文不附加测试副本声明或导入时间。订单及物流追问只在同一 `conv_id` 内复用最近单号，并重新查表取得修改后的值；新报价或其他话题不会沿用旧订单。
 - 订单数据仅为内部验收副本：`ORDER_DATA_TENANT_ID` 可固定服务器端租户范围，空值允许查询内部已导入样本。它不代替将来客户登录授权。没有管理页面或对外增删改接口；表数据在运行时 SQLite 内维护，导入脚本默认保留已有记录，只有显式 `--replace` 覆盖。源库连接凭据和快照文件均在仓库外，业务库只读，不随服务查询访问源库。
+- 节点导出：`scripts/export_order_tracking.py --database-env <显式环境文件> --orders-snapshot <私有订单快照> --output <新私有节点快照>`。仅需离线导出时安装可选 `PyMySQL`；脚本开启源库只读事务，只查询快照订单直接关联的入库完成、已冻结装柜和标准船节点，按客户与源订单 ID 同时匹配。随后运行 `scripts/import_order_test_data.py --snapshot <节点快照> --db <运行数据库> --tracking-only`；只更新已有订单的 `tracking_json`，校验源 ID，不改订单字段，默认保留已有轨迹。`--replace` 才覆盖手工轨迹。快照不随 Git 发布；将来 MCP 接入仍返回同一事实结构，无需改变卡片协议。
 - 历史卡片以 `__CARD__{json}` 保存；原 SQLite 表、字段、角色值和历史记录继续可读。历史正文和卡片使用存库时间，卡片恢复复制操作。切换话题或历史时取消旧流和待上传附件；等待建会话期间的新草稿不能被旧发送清空。历史刷新失败保留已有列表；删除或清空成功后先同步本地列表，并使先前的刷新失效，刷新失败或迟到均不恢复已删除记录。删除会话同步移除其人工会话及消息，迟到的模型写入不能生成孤立消息。
 - 人工申请使用 `conv_id`，返回 `session_id`，后续用 `sid`。状态为 `waiting/active/closed`，消息方向为 `customer/agent/system`。转接将 active 改为 waiting，列表只允许主动接入。备注保存在 `human_sessions.note`；撤回将原客服消息改为系统提示并追加带 `recalled_id` 的系统事件，轮询按原消息编号更新，重复撤回不追加事件。
 - 新建会话保存一条 assistant 欢迎语并返回 `welcome`，前端在首次用户消息之前显示。首次提问判定只统计 user 消息。服务评价用 `ratings` 保存，并汇总到管理统计。Excel 导出依赖 `openpyxl`，原 CSV 可用 `?format=csv` 访问。
