ROOT CAUSE

The double pinochle bonus is missing.

THE FAILURE

The double pinochle bonus is missing.

Unsuccessful approach: Treating two JD with one QS as double pinochle overpays.

Case contract

Input [hand, trump]. Arounds (one of the rank in each suit): A 100, K 80, Q 60, J 40; double around x10. Run in trump (A T K Q J) 150 each; marriages (K+Q same suit) 20, royal marriage in trump 40, but a K+Q used in a run is not also a royal marriage. Pinochle (JD+QS) 40, double pinochle 300. Return the meld total.

Why this case matters

Card-game engines, scoring apps and online tables apply this rule automatically on every hand.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 8 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

A bounded toy rule contract stated explicitly in the contract field; cards are two-character codes (rank, suit). Not a complete implementation of any published rulebook or casino table rules. 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.

Observations recorded using Python 3.12.14 at 2026-09-29T14:50:24.624120+00:00.
