Approved design for first-class array-valued local variables across the panel-logic (TS) and control-logic (Go) engines: array StateVar declarations (dynamic/capped/fixed sizing), an array-aware expression language shared by both engines, sizing-policy-aware mutation nodes (unifying the existing accumulate/export/clear arrays), persistence, and widget binding.
