# Foodservice ordering adapters

> Map source orders deterministically and certify restaurant edge cases with the LIP adapter kit.

`@loyalty-interchange/adapter-kit` defines a source-to-LIP contract and emits a
`lip.adapter-certification/1` report. It checks valid/reconciled foodservice
orders, deterministic replay, distinct operation keys, declared capabilities,
adjustments, line kinds, and tender types.

The reference corpus covers modifiers, combos, split tenders, comps,
discounts, taxes, tips, offline replay, duplicate delivery, voids, and partial
refunds. A green report covers only the supplied adapter and fixtures; it is not
a vendor endorsement.

For Square, Toast, Olo, PAR Brink, NCR Aloha, or Oracle Simphony, first map
stable order/check id, scope, item/modifier/combo hierarchy, discount vs comp,
tax/tip/fee eligibility, multiple tenders, business date, event time, and
source-linked refund deltas. Partner payload and retry details vary and must be
verified in an authorized sandbox before compatibility is claimed.

```ts theme={null}
import { certifyFoodserviceAdapter } from "@loyalty-interchange/adapter-kit";

const report = certifyFoodserviceAdapter(adapter, sanitizedFixtures);
if (!report.passed) throw new Error(JSON.stringify(report.cases));
```

Use `certifyAdapter` only for a clearly labeled partial run; it does not require
the complete shared foodservice scenario set.
