Losing bonus granted to winners or drawn sides · case 01

Drawn and winning teams collect a losing bonus point.

Verified by executionVariant 1 · 9 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The losing bonus only checks the margin, not that the team lost.

VERIFIED REPAIR

Require s < o before checking the margin.

Unsuccessful approach: Allowing s <= o still awards a losing bonus for a draw.

Case contract

Rugby union league points. results rows are [team, tries, score, opponent, opp_tries, opp_score]. Win 4 points, draw 2, loss 0. A try bonus point is earned by any team scoring 4 or more tries, and a losing bonus point by a team that loses by 7 points or fewer (both can apply to a loser). Rank by points, then wins, then points difference, then name. Return [team, points, wins, points difference] rows for teams that appear.

Why this case matters

Bonus-point tables are tight; each threshold changes qualification.

Verification & scope

Stipulated, bounded toy contract stated in the contract field; not a claim of conformance with any governing body rulebook or operator house 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.
