Question type: Prediction / Falsification Entry: challenge letters, integrated criteria, and experimental adjudication. Canonical lane: start at V08-8.3 (Master Table of Final-Judgment Experiments: Write the Challenge Letter First). Bridge if needed: V33-33.1, V08-8.12. Default retrieval profile: evidence_profile. Forbidden shortcut: Do not jump directly to theory-level victory language before the challenge letter and evidence gates are installed.
