The problem

Accounting platforms differ; automation needs a stable internal interface.

How it works

Coded transactions push through a LedgerPort → XeroMock / QBOMock implementations.

How the AI is built

Port/adapter boundary so domain agents never bind to a single vendor SDK.

Human review & control

Push failures and mapping conflicts return to a review queue.

Connected tools

Mock Xero & QBO adapters with identical domain DTOs.
