  "description": "A non-government organization taking part in a contracting process - a tenderer, a supplier, a funder - with the roles it plays. Government participants are NOT duplicated here: the buyer and procuring entity are _core GovernmentOrganizations, referenced directly from the process, so one body never becomes two entities. A scheme-qualified identifier is required: a supplier known only by name cannot be joined across contracts or to a company register, and unjoinable supplier data is the main reason procurement transparency fails in practice.",
