Group Family Map

ordered homogeneous peer ownership without current-selection semantics

Dark SVG source uses the VMx architecture palette and keeps arrows behind masked component boxes.

Peer shape

  • GroupVM preserves homogeneous collection behavior without Current.
  • Children are still owned and lifecycle-managed by the group.
  • The group itself may be selected by its own parent.

Events

  • Collection mutations publish the same collection-change contract as list-like containers.
  • Batch updates collapse many mutations to one Reset.
  • Lifecycle orchestration matches CompositeVM without selection work.

Best fit

  • Use groups for toolbars, notification stacks, peer panels, and capability rows.
  • Use CompositeVM when current selection matters.
  • Use AggregateVM when child roles are fixed and heterogeneous.
