The worker builds the current translation matrix with x/y/z and stores operand 2 in the channel record. This is distinct from the shared range transform at 0x229. The C# handler sets V24 directly and is therefore position-correct but does not yet model operand 2."
evidence = "Ghidra /v2 assembly: op_0x22f_set_gfx_range_translation_target@0x423b00 loads ECX with retained-gfx owner ctx+0x46614 before calling gfx_range_transform_set_translation_target@0x472e90. The worker writes owner+0x428's embedded object fields: active bit, shared start obj+0x34, delay obj+0x44, duration obj+0x58, and target translation matrix obj+0x1ac. It never resolves an ordinary object handle. FIELD@0xb4d8 supplies (0, pan_duration, target_x, target_y, 0) while the following 0x220 animates the minimap viewport marker over the same duration."
