Build clinical decision support safety checks

Implement drug interaction and dose validation checks

When building medication safety checks that must block critical interactions and never silently fail.

• · Current medications list
• · New drug
• · Patient weight/age/renal function

• · InteractionAlert[] sorted by severity
• · DoseValidationResult with suggested range

• · Drug interaction database

Patient data available; drug database loaded; pure function architecture required

• · Silent pass on critical interaction
• · Missing weight blocks prescribing instead of validating
• · Bidirectional interaction pair mismatch

• · Zero-tolerance for false negatives
• · Pure function architecture (testable)
• · Weight-based, age-adjusted, and renal-adjusted rules all documented
