Calibration note. Weights are ordinal and reflect literature where published LRs exist (visual hallucinations ~3× more common in secondary psychosis; ~62% grandiose delusions in mania) and the reference document's framing elsewhere. Probabilities shown are relative ranking, not calibrated posteriors. Red-flag layer operates independently of scoring. Decision support only — not a substitute for clinical judgment.
