Next compensating actions.

Member previewVariant 4 · 3 implementations · 60 checks per implementation

Case contract

A client numeric patch journal retains insertion order. Accepted patches move to the base; rejected patches are removed and compensate in reverse order; pending patches remain visible. Identity and zero-valued patches are significant. Operation next-compensating-actions has the six explicit input/output oracles below.

Why this case matters

An offline client lifecycle model that isolates a state-management defect without DOM rendering or network services.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
