LongHarness separates source-linked evidence from evolving conclusions, using unresolved gaps to guide searches and revising conclusions when new evidence arrives. On OfficeQA Pro V2, GLM-5.3-Flash with LongHarness scored 61.1% exact match, versus 4.4% for direct reasoning with the same backbone. The direct model received BM25-retrieved passages in a 256K-token window, so this was not the same open-corpus search setup.
