Delivery acceptance: late storage charge · case 01

Storage charges begin before the stipulated post-deadline period.

ROOT CAUSE

Storage charges begin before the stipulated post-deadline period.

THE FAILURE

Storage charges begin before the stipulated post-deadline period.

Unsuccessful approach: The attempted repair uses x["storage"] if x["now"]>=x["deadline"] else 0; the explicit regression cases demonstrate that this still violates the stipulated auction rule.

Case contract

Award fulfillment tracks delivered, inspected, rejected and accepted units. Title and seller payout require acceptance, not shipping. Partial shipments and certificates refer to individual auction lot identifiers; freight and storage are fixed integer credits. Named decision late-storage-charge: For late storage charge, apply the stipulated decision x["storage"] if x["now"]>x["deadline"] else 0.

HELD IN THE MEMBER ARCHIVE

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

This mechanism has 10 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

Stipulated toy auction rules, not a venue specification, financial advice, optimization claim, or live trading implementation. Nonnegative integer inputs and internally aligned list fields only. 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.
