Gate + Receipts · design-partner lane
Source-anchored answers, fail-closed refusals, and receipts a buyer can verify.
This is the common spine under the CDS proof demos. The system either cites the source, refuses or flags the gap, and leaves a tamper-evident record. It is in design-partner validation, not a self-serve product.
Can the answer be traced to source?
Did the system refuse when the record was not enough?
Can a reviewer verify the output was not altered?
Does the human keep the final judgment?
