+"""Adapter for the bypos-collector output (central product library zc.bypos.net).
+
+The ``bypos-collector`` tool (see ``tools/bypos-collector``) queries the same
+central product library that the 云店 POS uses when adding a product by barcode,
+and writes one JSON object per line (JSONL) with these fields::
+
+    barcode name spec unit area manufacturer license
+    in_price sell_price status retmsg fetched_at source
+
+This module turns one such record into the internal product shape consumed by
+:func:`opengoods.etl.load.load_bypos_record`. It is a pure function (no DB, no
+network) so it is easy to unit-test.
+
+The central library is a Chinese retail catalogue: it provides 品名/规格/单位/
+产地/厂商/建议价 but **not** ingredients or nutrition, so no ``food`` block is
+produced.

 ## 配置
 
-- `sdogid`:中心库账号 id(本项目所属云店账号的授权 id)。默认值见
-  `collect.go` 的 `defaultSdogID`,也可用 `-sdogid` 参数或控制台覆盖。
-  **这是账号级凭证**——若本仓库对外公开,建议改为从环境变量/外部配置读取。
+- `sdogid`：中心库账号 id（本项目所属云店账号的授权 id）。
+  优先从环境变量 `BYPOS_SDOGID` 读取，其次是命令行 `-sdogid` 参数，
+  也可以在 Web 控制台的输入框中填写。**三者都未设时启动会警告、开始采集时会报错。**
+- 网络错误自动重试（最多 3 次，指数退避 500ms/1s/2s）。
+
+## 导入 goods/天工库
+
+采集得到的 JSONL 用 ingestion 里的导入任务入库(只导入 `status=hit` 的记录,
+按 GTIN 去重 upsert,重复导入幂等):
+
+```bash
+cd ingestion
+python -m opengoods.jobs.import_bypos --input products.jsonl
+# 可选:--limit N 限制条数;--dsn 指定数据库
+```
+
+字段映射:`barcode→gtin`、`name→name`、`spec`(可解析的质量/体积如 500mL/5kg)
+`→net_content`、其余规格/单位/产地/许可/进价留存到 `attributes`、`sell_price→`
+CNY MSRP 快照。来源记为 `bypos中心库`,带字段级 provenance。
