Authority and evidence boundary. K07 publishes knowledge architecture, bounded reference records, procurement structures, local validation tools, signed synthetic fixtures, and point-in-time source review. It does not certify a facility, award a contract, authorize an operation, prove truth, establish deployment, or claim current operation.
