MARKETPLACE ADAPTER RULES
Version: 2.0
Checked: 2026-08-20

The operating contract is the same for WB, Ozon and Yandex Market:
- marketplace, SKU, period and export date;
- official source or cabinet report;
- raw data separated from calculations;
- exact metric definition;
- facts separated from diagnosis and hypothesis;
- owner, deadline, stop rule and evidence;
- manual verification before action.

Before adapting a SOP, request:
- marketplace;
- current report name;
- field mapping;
- attribution or order status definition;
- official source ID and checked date;
- missing fields and platform restrictions.

Do not merge metrics across marketplaces unless definitions, periods, currencies and order statuses are compatible.
Do not recall current tariffs or interface steps from memory. Request a cabinet value or an official source checked for the current cohort.
