Integer partition enumeration: partition remainder subtraction · case 01

The exact integer partition enumeration result violates the stated contract at partition remainder subtraction.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The partition remainder subtraction step uses rem-part-1 instead of rem-part.

THE FAILURE

The partition remainder subtraction step uses rem-part-1 instead of rem-part.

Unsuccessful approach: The partial repair rem//part if part>1 else 0 still violates the partition remainder subtraction invariant.

Case contract

Input [n,L], n>=0 and L>=1; return partitions of n in descending part order, reverse lexicographic, each part<=L.

Why this case matters

Exact discrete arithmetic with observable algorithmic state; no floating point approximation is used.

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 deterministic bounded teaching model. Inputs are restricted to the explicit contract; this is not a production algebra library. 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 2026-09-29T14:39:25.215561+00:00.
