按期累积（新 recipe_accumulate；table_versions 扩展） - 按统计期出的交叉表报表首次导入时默认「按期累积」，由人确认；一期一个构建，两期及以上物化成一份新的 SQLite 快照，不用视图 - 统计期完全相同要勾「替换该期」，部分重叠拒收，中间有空缺要确认；物化前逐期核对库哈希和行号，并集上另加行数守恒、主键唯一、日期落在所属统计期三条核对 - 配方演进分三档：新增列（早期各期为空值）、退役的列和表保留旧值（只在这次才退役时要勾）、不兼容变化只能显式「重新开始累积」 - 快照 id 在累积时含目标配方和模式；同样的输入物化两次库哈希相同，同一文件换名再传直接复用 - 说明按期合并，任何一期没核对过就不写「已核对」；各期维度取值不同、退役列、合计表都有提示，经过数字检查 修复按钮（新 recipe_fixes；执行器给问题带结构化参数） - 加入标签、移除标签、声明为合计行、分段标题改名、编辑恒等式成员、按锚点忽略行/列/区域外文字、声明占位符、声明隐藏行处理、工作表改名 - 服务端算补丁，先预览新旧配方对照、再应用，可以撤销；补丁封闭，不引入正则、自由文本常量和写死坐标；修复进确认清单 - 只改分段标题、新标题仍含原来选的词时沿用已确认的常量，不算破坏性变更；修复后只查改动过的段的认领，没改的关系交给试运行核对 框选转锚点（新 recipe_select） - 网格上框选（鼠标、键盘、区域输入），按八种用途换算成按文字认的锚点，立刻干跑比对；配方里不存坐标，泛化不了时列出原因 - 整张表挪位后同一配方照样认得；框进合计行、夹着小计、表下说明都有明确的处理 确认与对照（recipe_confirm、recipe_diff、新 recipe_compare） - 改配方后确认清单只列有变化的项（同时按本期数据比较），不用每修一次重勾十来项；新旧配方对照界面；按规则重新起草并把名字对齐到现行配方 - 改配方后已体现在配方里的回答保留，矛盾的列出来请人重答 - 「排除的行」写进回执和导入清单：隐藏行、跳过的空行、按配方忽略的行、停止后的文字行、只核对不另存的合计行 版本页（新 source_versions、api/source_versions；前端 VersionsDialog） - 快照与导入记录列表、启用旧版本（可写理由）、查看清单、移除一期、作废接受、清除原件；写操作带界面看到的当前版本，并发改动回 409，不静默丢期 - 除当前版本和被运行引用的版本外，再保留最近 3 个版本供回滚；遮罩列丢失要明确确认 期 1、期 2 遗留 - 重传撞上被改过的构建文件：能用本次上传恢复就隔离旧文件再恢复，否则回 409，不再是 500 - 跳过空行的列表不再把表下隔一行的说明读成数据；不像说明的单格行要人确认；受影响的配方构建换 id - 版本存储加进程级文件锁：第二个进程拿不到锁时不清理、不回收，写操作回 503（部署本来就是单进程）

"""上传表格的版本页接口（期 3，WP-5；P3-SPEC 第 7 节）：版本列表、启用旧版本（回滚）、查看清单、移除一期、
|
||
作废接受。导入记录列表与清除原件仍在 datasources.py（期 1 的接口，期 3 补了字段和错误码）。
|
||
|
||
流程在 app.data.source_versions 里，这里只做三件事：手工读请求体（不触发 FastAPI 自带的 422：它的 body 是
|
||
{detail: [...]}、不带 code，前端没法分支）、取署名、把业务错误转成带机读码的 CodedHTTPException。
|
||
|
||
**写操作一律要 confirm: true 和界面看到的当前版本（expected_current_snapshot_id）**（7.7）：确认框是按那个版本
|
||
写的后果，别人在这期间提交、启用过，锁内比对不上就 409 base_changed，不能照旧切过去。移除、作废还要写理由。
|
||
署名取请求体的 signed_by，其次请求头 X-Actor，只原样记下（未认证）。
|
||
|
||
路径都是 /{source_id}/snapshots… 和 /{source_id}/imports/{import_id}/(manifest|remove|revoke-acceptance)，与
|
||
datasources.py 的 /{source_id}/imports（GET）、/{source_id}/imports/{import_id}/purge-raw 不重叠；在 main.py 里
|
||
登记在 table_imports 之后、datasources 之前。
