+## Slice 11 - Business Overview Trading Margin Proxy Bridge
+
+This slice opens a company-period trading-margin proxy lane where the evidence is concrete enough, while keeping the accounting boundary explicit.
+
+It does not claim clean profit, бухгалтерский финрезультат, or exact cost-of-sales margin.
+
+Implemented now:
+
+- `inventory_trading_margin_proxy_for_organization` exists as a bounded recipe over the reviewed purchase/sale document union on `41.01`;
+- explicit-period business overview can execute this document probe beside money-flow/activity, VAT/tax, debt-position, open-settlement quality, and inventory probes;
+- the pilot derives sales revenue, purchase-document cost proxy, gross spread proxy, margin-to-revenue, markup-to-purchase-cost, and top items only from confirmed товарные document rows;
+- the answer adapter surfaces this as `торговый margin proxy`, not as чистая прибыль or accounting margin;
+- the unknown family narrows from generic `profit_margin` to `accounting_profit_margin` when the proxy exists, so the user sees both what is now supported and what remains unproved;
+- all-time business overview does not silently reuse the prior period's trading proxy, because the probe requires a fresh explicit period window.
+
+This is a material breadth step for broad company analysis, but it is still not full company-wide profit analysis. Exact profit/margin still needs reviewed evidence for себестоимость продаж, expenses, period closing, and accounting result.
