补齐人工回单验收用例的原件依据（09-17-company-loan-principal-repayment）

报销付款主链路手工录入回单字段时，显式提交合成正式回单的原件依据和已核对声明，不再依赖受限本地解析一定成功。保留拒绝自审、独立复核、最终付款和下游收口断言。

记录安全的凭证类别、来源及失败业务原因，避免只留下通用 VALID_001。首轮完整候选的 371 项浏览器通过及 1 项失败原样保留；因原记录缺少具体原因，不将解析超时追认为已确认根因。

验证：回单服务端定向 93 项通过；受管隔离环境的报销付款主链路通过并完成核销、下游收口及自有资源清理；任务、流程、文档、敏感和差异检查通过。

仅修改测试 helper、规约和任务记录，应用资金规则、解析限时、数据库及正式门禁范围未改。后续对本提交重新运行完整 verify-candidate。

独立代码复核及真实还款验收待完成；未推送、未部署、未访问生产或写入真实业务数据。
