Initial domain

Procurement

The Procurement proof set is the first public ABCS domain. Its purpose is to validate the specification model before expanding coverage.

`procurement.purchase-order.get`	Retrieve one purchase order by a supported identifier.
`procurement.purchase-order.search`	Find purchase orders using supported business criteria.
`procurement.purchase-order.create`	Create a new purchase order.
`procurement.purchase-order.update`	Change permitted attributes of an existing purchase order.
`procurement.purchase-order.submit`	Submit a purchase order into its applicable review or approval flow.
`procurement.purchase-order.approve`	Record an authorized approval decision.

Receipt

These definitions are intentionally application-neutral. Application-specific APIs, field mappings, authentication, transport, and implementation constraints belong to implementations—not the ABCS capability identity.

Machine-readable source

The repository includes the Procurement YAML source, the capability JSON Schema, and an example capability document.
