Sparse tensor: stored entry count is reported instead of logical nonzero count · case 02

stored entry count is reported instead of logical nonzero count.

Member previewVariant 2 · 3 implementations · 6 checks per implementation

Case contract

Coalesce duplicate coordinates, remove final zeros, and return the count of remaining logical coordinates.

Why this case matters

A small offline sparse-array operation has explicit coordinate and storage semantics.

One recorded failure

Sample boundary fixture

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