一、文案（前端约 1600 处，后端传到界面的约 880 处） - 术语统一：工作流层面用「运行」（继续运行、重新运行、试运行），节点和工具层面用「执行」，不再用「跑」； 总时长 / 执行时长 / 等待审批；服务端；助手；Agent；token；工作流；固定版本；模型接入；系统提示；批准 / 驳回；受管级别 - 口语改书面：取不到、没取回来、读不懂、连不上、多半、照样、兜底、揉成这类说法改成「无法 / 未能 / 失败 / 请」；去掉拟人写法 - 不再露出实现细节：界面上不写 checkpoint、同一拍、哈希（凭证处除外），不写改版历史（「以前…」「老数据」）； 报错、校验、门禁、自动修复里裸写的配置键名和枚举值换成界面上的中文标签，由新的 backend/app/engine/labels.py 统一提供； 发布弹窗里结论句的选项不再是 off / require_citation - 同一件事只留一种说法：生成阶段文案、出具档位说明、画布锁定提示各合成一份 - 去掉界面上的工业场景示例（MES、ERP、「张工」「王工」）和真实产品名，换成通用示例 二、说错的提示（都有测试证明） - 数据库测连接失败时的专用提示以前从不出现（按报错文字全等比较，永远比不上）：改为按错误类型判断，不再拼出重复的前缀 - 「设置 → 供应商」改指「设置 → 模型接入」；「在设置里建数据源」改指「数据」页 - 缺少 API Key、模型接入已停用的报错不再夹英文，写明去哪里填 - 两处原因说错（「这种引用在后续版本支持」「这一版还不支持」）改成真实原因 - 节点说明里不准确的说法改正：代码节点在 microVM 或系统沙箱中执行；报告撰写、口径卡的说明不再说过头 - 导出的证据 CSV 里两列同名，第三列改为「片段编号」 三、前后端对齐 - 前端按后端原文识别日志、报错的地方，新旧两种写法都认得（历史运行里存的是旧文字），逐条补了新旧原文的核对 - 后端交回模型的原指令放进单独的 for_model 字段，前端在解析响应时去掉，不会显示到界面上 四、检查 - 检查脚本里按原文匹配的断言改成新文案；改完会变成永远成立的反向断言逐条修正，并做了变异验证 - 新增 check-copy（静态扫描前端界面字符串和后端上界面的文案）：再出现「跑」「后端」「多半」「令牌」、 界面上的 Copilot、裸写的配置键名、半角标点等就报错；确需保留的写进 scripts/copy-allow.json 并注明理由

"""引文：[[q:K1|原话]] 必须在那次检索命中的片段里逐字出现。
|
||
|
||
知识库的结论以前只能写成 [[see:K1]]：读者知道依据是哪次检索，看不到是哪一句。引文把
|
||
原话写进报告，系统拿检索快照（取回时复验哈希）逐字核对：
|
||
|
||
- 空白归一化后逐字出现才算有出处；改一个字就是没有出处（state none，issue unresolved_ref）
|
||
- 正文里显示引文本身；目录里根本没有这次检索时显示占位，和别的解析不了的引用一样
|
||
- eid 带上命中片段的定位：第几条命中、原文里的起止
|
||
- 出口复核重新取快照、重新比对，不信文档里记的结论
