 `carrier_type`（迁移 `107_product_catalog_carrier.sql`）是后台「商品与成本中心」的分区维度：自动发货 / 接单平台 / 人工 / 共用。回填口径（2026-10-22 修正）：只把**真正走 affiliate-dash 执行器**的商品算作 `affiliate_dash`——以 `fulfillment_tasks.executor_key='affiliate_dash'` 的履约证据为准，按 `context_json.skuCode` 建标准商品（`aff:<skuCode>`，生产快照 41,676 条任务 / 28 个 SKU）；接单模板初始化出来的 `tpl:*` 商品全部是 `work_order`（662 个）。**渠道映射只代表平台 SKU 能归一到标准商品，不代表自动发货**。人工/共用由后台按需手工调整；新增自动发货 SKU 可在页面点「同步自动发货商品」补建。
 
+上游自动发货商品价格用 `apps/backend/scripts/sync-affiliate-dash-prices.ts` 批量导入（价格清单见 `apps/backend/scripts/data/affiliate-dash-prices.json`）：按 `aff:<skuCode>` 补建/更新商品，并给指定成本项生成 `scope=product` 的按件版本；金额取上游 `cost_amount`（分），价格变化时先停用旧版本再插入新版本，历史快照不变。示例：`npx tsx scripts/sync-affiliate-dash-prices.ts --cost-item-id=5`。
