+### 0x61 `lookup-array` (lookup-array, argc 3)
+- **summary:** Take a typed reference to base[index], preserving whether the base belongs to local or global storage.
+- **grounding:** source=investigation, confidence=high
+- **evidence:** HISTORY.BIN copies x/y tables into local-int cells 0x4 and 0x68, then lookup-array local-ptr <- local-int base supplies every right-side button and hovered-row draw coordinate. Treating the local operand's current value as a global base collapses those draws to (0,0); retaining the local address yields the native x=768/y=121..549 positions. RECOVER.BIN independently exercises the same pointer destination with global bases.
+
+Operand 2 names the base cell itself: a global-bank operand produces a global reference and a local-bank operand produces a local reference. Operand 3 is added as the element offset. Pointer destinations retain that address domain; reading or writing the pointer dereferences the corresponding bank. Non-pointer destinations receive the addressed value. The same domain-preserving address model applies to lookup-array-2d (0x12c).
