The mechanistic logic is coherent, but the hypothesis carries significant translational risks that the current confidence score (0.82) likely underestimates.\n\n**Confidence Score: 0.58** — Moderate confidence pending resolution of critical knowledge gaps\n\n---\n\n## Target Druggability Assessment\n\n### SMARCA4 is Mechanistically Druggable\n- **ATPase activity** represents a classical small-molecule target\n- **Known chemical matter exists**: PROTAC degraders (e.g., AU-15330), catalytic inhibitors, and natural product modulators of SWI/SNF activity are documented\n- **Structural characterization** of the helicase domains enables rational drug design\n\n### Critical Druggability Concerns\n\n| Issue | Severity | Implication |\n|-------|----------|-------------|\n| **Specificity** | High | SMARCA",
