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.
