Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

Membership is active if the flag is set and today is on or before the expiry day. Active members have surge capped at 2.0x (20 tenths) and, when the (capped) surge is at most 1.5x, get 10% off the surged fare (floored); fees are never discounted. Return the amount due in cents.

Why this case matters

Ride-hailing prices are computed per trip at scale; ordering, unit and boundary slips become systematic over- or under-charging.

One recorded failure
