krummholzIn a fictional forestry case from the public Maine Evidence QA preview, an archive has no 1988 survey entry. A second passage explains that pre-1990 surveys were kept on paper maps.
A useful answer needs to preserve the distinction: no archive entry does not prove the survey never happened. It should also identify the paper-record lead given in the source.
Keep uncertainty connected to the record.
The record includes the question, supplied passages, an expected answer and a scoring rubric. You can inspect the reasoning being tested rather than relying on the fluency of an answer.
The case is synthetic. It is not a report of an actual archive search or evidence about a real survey. Its record ID is gen_missing_evidence_0045.
