Proxy instructions: remaining proxy size · case 01

A partially filled proxy resubmits its original full size.

ROOT CAUSE

A partially filled proxy resubmits its original full size.

THE FAILURE

A partially filled proxy resubmits its original full size.

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

Case contract

A bidder authorizes a bounded proxy to submit offers for a specific lot. A proxy instruction specifies a price ceiling, per-step increment, remaining quantity, owner consent and a one-use trigger token. Outputs are actionable submissions, not an optimal bidding strategy. Named decision remaining-proxy-size: For remaining proxy size, apply the stipulated decision max(0,x["quantity"]-x["filled"]).

HELD IN THE MEMBER ARCHIVE

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

This mechanism has 9 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 2026-09-29T14:46:09.089975+00:00.
