补齐 code-review 遗留 2 项：审批单此前只固化 ref_id/refer_no 指针，复核者看到 的是业务当前内容；二次分配方案在编辑替换与驳回清空时一律物理删除，方案事实 无处回溯。 - 审批单加 version_no 与 snapshot_json（信封 schema_version/order_type/ captured_at/data）；二次分配、月结、调整单三类提交均固化送审内容，开关关闭 的自动通过路径同样写快照；详情按 snapshot/live/missing 三态回显，历史单 只读回退当前内容并显式告警，不回填历史快照 - 二次分配方案行改 append-only 版本化（version_no/is_active，唯一键扩为 business+version+personnel）：编辑替换与驳回清空只置历史，核算与详情默认 只取生效行，业务详情新增 allocation_history - 送审内容未变不重提、方案未变不新增版本：判据统一为送审内容，两个 version_no 语义解耦（方案版本=内容第几版，审批单版本=第几次送审） - 审批单列表、工作台待办、审批超时预警三处 defer 快照列，避免整列拉取 - 月结提交取行加 for_update，防并发提交算出重复的审批单版本号 - 修复审批类型筛选上界 le=2（调整单无法筛选）、快照金额把空值写成 0.00 - V11 迁移三件套同步（Alembic / db/migration / init-dev.sql） 测试：单元 +16（方案内容比较 10、审批入参 6）、集成 +12；全量 891 passed。 Co-Authored-By: Claude Code <noreply@anthropic.com>
