A resume cursor stops at an empty batch instead of normalizing · case 04

A resume cursor stops at an empty batch instead of normalizing.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Fetch at most quota rows from a sequence of batches starting at [batch-index,row-offset]. Skip exhausted and empty batches, return the emitted rows and a canonical next cursor, and mark exhaustion as [number-of-batches,0]. Quota zero preserves a normalized cursor.

Why this case matters

A bounded deterministic data engine model makes representation and changelog faults reproducible.

One recorded failure

Sample boundary fixture

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