Delivery slot awards: maintenance exclusion · case 01

Maintenance blocks either no requested slot or every auction slot.

ROOT CAUSE

Maintenance blocks either no requested slot or every auction slot.

THE FAILURE

Maintenance blocks either no requested slot or every auction slot.

Unsuccessful approach: The attempted repair uses not x["maintenance"]; the explicit regression cases demonstrate that this still violates the stipulated auction rule.

Case contract

An auction awards delivery capacity in discrete named slots. A bid may require several consecutive slots, setup occupies an earlier slot, and cleanup occupies a later slot. Existing commitments and a separate seller maintenance mask must both constrain certificates. No continuous scheduling optimization is claimed. Named decision maintenance-exclusion: For maintenance exclusion, apply the stipulated decision not set(x["requested"])&set(x["maintenance"]).

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.

Observations recorded using Python 3.12.14 at 2026-09-29T14:46:13.933302+00:00.
