 >   `0.1.12`），由 `scripts/version.py` 从 git **算出来**；开发交付的独立说明写入本文件“开发快照”章节，并打 `snapshot/vX.Y.Z` 注释标签 ⇒ 每次开发交付均可追溯，

+## 开发快照 snapshot/v0.1.55 - 2026-10-25
+
+### Changed
+
+- 问题流水表首批到达即可浏览，后续在后台自动续载；列表仅传轻量文本预览，完整问答/引用/媒体按需读取，完整明细另行导出，避免等全部正文下载后才显示。
+- 新增是否覆盖、是否正确、产品分类、问题类型、根因分析五项筛选，可与时间/关键词组合并查询未设置值；后端按完整总表的当前有效标签筛选，列表、看板及导出条件一致。字段筛选时不套用无明细的历史汇总。
+
+### Fixed
+
+- 续载异常明确保留已读部分和失败状态，查询变更取消旧请求；详情保存和AI更新不被迟到分页覆盖，完整导出拒绝使用截断预览或不完整结果。
