1. Parties and goods. Buyer purchases the machined housings listed in Section 2 from Supplier.

"This Agreement consists of Sections 1 through 7 set out in this document; there are no schedules or incorporated terms.",
"Neither party has a right to terminate this Agreement for convenience.",
"The supplied text contains all seven sections of the executed Agreement and no attachments or amendments."
] | The supplied material identifies itself as the complete agreement, states that there are no schedules or incorporated terms, and expressly provides that neither party has a termination-for-convenience right. The claimed absence is therefore directly supported by the complete text. |

"Seller will make the relevant records available and provide reasonable assistance."

Contract Clause Absence and Evidence Insufficiency Verification Benchmark
This benchmark focuses on negative claims about procurement and sales agreements. It provides contract text with known document coverage; the material may be complete or partial. Each example assesses whether the available material proves that a specified right, restriction, or responsibility is absent, distinguishing proven absence from insufficient evidence, contrary evidence, and inconclusive records. It supports training and evaluating legal document verifiers for contract review, evidence assessment, and cautious reasoning.
