个时间字段仍为待补全，没有错误提示。 +- 影响：缺失任务无法自动完成，技术支持容易误以为信息已保存。 +- 建议：修复前端时间序列化或后端字段映射；保存失败时保持表单打开并显示字段级错误。 + +### LIFE-02：“分派处理人”打开了错误表单 + +- 严重度：阻断。 +- 复现：待处理状态点击页头主操作“分派处理人”。 +- 实际：打开的是“补全工单信息”，且没有处理人字段。 +- 影响：技术支持无法通过主操作完成责任人分派。 +- 建议：提供独立分派弹窗或在表单中加入处理人字段，并在保存后更新页头。 + +### LIFE-03：未分派也能进入处理中 + +- 严重度：高。 +- 复现：处理人未设置时，从“更多工单操作”选择“开始处理”。 +- 实际：状态成功变为“处理中”，页头继续显示“处理人：未设置”。 +- 影响：责任归属与业务状态不一致，工作台和 SLA 统计可能失真。 +- 建议：状态机在进入 `in_progress` 前强制校验处理人，或将当前操作者自动设为处理人并记录事件。 + +### LIFE-04：正式客户回复任务未生成 + +- 严重度：高。 +- 复现：支持分析结束后进入待确认状态。 +- 实际：页面长期显示“正在生成正式回复任务”，没有可编辑、发送或确认送达的任务区域。 +- 影响：页面要求使用正式回复任务，但用户只能记录客户可见活动，回复闭环不完整。 +- 建议：失败分析也应创建人工回复任务；任务生成失败要显示重试或人工创建入口，并阻止在未确认回复状态时直接解决。 + +### LIFE-05：智能受理等待时间显示不准确 + +- 严重度：中。 +- 实际：受理已经运行数十秒，页面仍显示“已等待 0 秒”；最初长时间停在“准备受理…”。 +- 影响：用户无法判断是否卡住或需要转人工。 +- 建议：以服务端运行时间或稳定的客户端计时器显示耗时，并设置超时、重试和转人工提示。 + +### LIFE-06：支持检索候选与问题无关 + +- 严重度：中，属于知识和检索质量问题。 +- 实际：OIDC 回调白屏问题冻结的 3 条依据均为采集账号密码或采集进度内容。 +- 正面表现：可信校验拒绝了无引用输出，没有自动推荐或自动解决。 +- 建议：加强关联系统、模块和错误码的过滤权重；低相关候选不足时明确返回“无可靠依据”。 + +### LIFE-07：知识沉淀环境未就绪 + +- 类型：环境配置阻塞。 +- 实际：点击“评估知识价值”提示“尚未发布知识蒸馏 Agent”。 +- 影响：已解决工单不能进入知识草稿流程。 +- 建议：部署验收清单增加知识蒸馏 Agent 发布检查，并在工作台提供配置就绪状态。 + +### LIFE-08：结束状态仍显示“继续人工排查” + +- 严重度：中。 +- 实际：工单已解决或已关闭后，失败的支持分析仍显示“继续人工排查”按钮。 +- 影响：与“结果只读保留”的文案冲突，容易让用户误以为还能修改已结束工单。 +- 建议：结束状态仅保留分析结论、引用和运行轨迹，隐藏所有处理型按钮。 + +## 7. 当前版本的人工降级路径 + +当自动能力不可用时，按以下顺序确保工单仍可完成： + +1. 智能受理失败：保留材料，切换普通表单或人工接管。 +2. 时间字段无法保存：在内部备注记录已确认时间，并登记缺陷，避免重复建单。 +3. 无法分派：由有权限的支持人员从更多菜单接管；修复前需在线下明确责任人。 +4. 支持分析失败：保留冻结依据和运行 ID，点击“继续人工排查”并记录实际结果。 +5. 正式回复任务缺失：记录客户可见进展，并通过既有受控渠道发送；在活动流记录送达和确认。 +6. 知识评估未启动：在关闭说明中登记原因，后续由知识管理员人工创建草稿。 + +人工降级不得绕过权限、生产变更审批、客户确认或审计要求。 + +## 8. 关闭前检查清单 + +- [ ] 工单标题、描述、环境、系统和影响范围准确。 +- [ ] 处理人明确，责任归属可追溯。 +- [ ] 支持分析结论已核对，引用可信边界清楚。 +- [ ] 实际排查结果已经写入内部备注。 +- [ ]

自动建单 → 人工接管 → 处理中 → 支持分析安全降级 → 内部排查 → +客户可见记录 → 待确认 → 已解决 → 已关闭 → 运行审计`。 + +状态主线和统一活动流已经具备连续处理能力，支持分析在没有可信引用时也能安全降级。 +但“处理人分派、业务时间保存、正式客户回复任务、知识蒸馏 Agent”仍存在阻断或环境缺口。 +在这些问题关闭前，不建议把本次结果解释为生产业务闭环已经完全通过。
