+## Record Rule
+
+- Do not rewrite or backfill the existing `delivery_prediction_records.md` content when the record format changes.
+- For every future appended record block, add a `记录时间` column to the candidate-result Markdown table.
+- Use the report generation time after the query completes as the record time. Every candidate row in the same query uses the same value in `YYYY-MM-DD HH:mm:ss +0800` form (with the actual local UTC offset).
+- Record-table columns follow this order: `序号`、`记录时间`、`型号`、`推荐类型`、`差异项`、`API状态`、`AM516预测交期`、`可用库存`、`主导因素`.

 ## Output Selection
 
 - Prefer `data.交期汇总.AM516预测交期` when the API returns it and AR51 confirms it is usable.
