INR-guided weekly dose adjustment and daily plan: weekly total rounding · case 01

A 22.75 mg weekly requirement rounds down to 22.5 mg.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The half-milligram rounding truncates.

VERIFIED REPAIR

Round the weekly total half-up to 0.5 mg.

Unsuccessful approach: round() half-to-even still rounds some quarter values down.

Case contract

Input {inr, weekly_mg, low, high}. Toy table: inr >= 5 HOLD and weekly x0.85; high < inr < 5 x0.90; low <= inr <= high CONTINUE unchanged; low-0.5 <= inr < low x1.05; lower x1.10 (ADJUST otherwise). New weekly total rounds half-up to 0.5 mg; the plan spreads it over 7 days in 0.5 mg units as evenly as possible with the larger doses on the first days. Return {action, weekly_mg, plan}.

Why this case matters

Weekly anticoagulant adjustment combines threshold bands with a dispensing plan; band edges and the distribution rule are independent defects.

Verification & scope

A deterministic toy software model with explicitly stipulated thresholds and formulas; it is not clinical guidance, not a validated medical calculator, and makes no claim of conformance to any published protocol. Numbered variants vary patient and order inputs. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
