Fact 金额字段是 DecimalField(max_digits=44, decimal_places=24),PostgreSQL 把 NUMERIC(44,24) 原样读回,/api/query 的 JsonResponse 对 Decimal 直接 str(),把 24 位存储尺度尾零(如 1000.000000000000000000000000)暴露给 前端与 e2e;SQLite 无此尺度所以本地从未复现(formula-export e2e 在 run 1959/1961 失败的直接原因)。 复用 evidence 接口既有的 amount_text 归一化,新增 AmountJSONEncoder 只覆盖 Decimal 分支;assistant 等内部消费 analyze() 的路径仍拿到 Decimal,不受影响。前端所有数值都经 Number()/format() 解析,格式变化 透明。新增单测锁定 encoder 行为及 /api/query 汇总值输出。
