Table grouped row projection: group key namespace · case 03

The table group key namespace result violates the stipulated table grouped row projection contract.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Table group headers retain stable namespaced group keys distinct from labels, count visible members, derive tri-state selection over visible children, honor empty/collapsed group policies, and reset row striping within each group.

Why this case matters

An offline table UI model isolates table grouped row projection, including adversarial row/column relationships.

Sample boundary fixture

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