KOS_OP_ITEM_STORE_VAR

• Style: VAR (the value’s name).

• Stack: [..., obj, key] → [...]. Set obj[key] = value with the object on the stack, the key on the stack and the value resolved by name.

• Cache: none; a VAR row survives lowering only for a name with no fast slot.

• Compiler form: Folded by the compress pipeline from VAR value, ITEM_STORE. May lower to ITEM_STORE_FAST.

• Implementation: koskari/lib/opcode/ITEM_STORE_VAR.c
