Re-research, verify, and reframe a load-bearing, contestable claim from under-evidenced to evidence-dense and honest. Use to deepen or harden a thin or only-asserted claim — pose a sharp testable question, fan out read-only breadth-search subagents, fetch-verify every identifier and figure against the live source, synthesise honestly (reframe on overreach), let the author set claim strength, then fold the verified evidence into the working ledgers. This is the re-research LOOP that produces evidence; to audit defensibility of prose that already exists, use claim-audit instead.
