Temporal ordering
what this tests
Find the earliest or latest message in a folder or label and report its subject line exactly.
Date reasoning over many documents catches agents that stop at the first plausible hit instead of establishing the true boundary of a set.
Grading: Answer must match the true boundary message's subject (normalized for case and whitespace; a stray Re:/Fw: prefix is tolerated).
