Each Universal Router address now carries the mask its own source reads a command's type with: 0x1f for UniversalRouterV1, 0x3f for V1_2 and V2, 0x7f for V2_1_1 and V2_1_2. The fixed 0x1f dropped the 0x20 bit, so EXECUTE_SUB_PLAN (0x21) was listed as a V3 exact-out swap. A sub-plan step is now listed as "Execute Sub-Plan (its steps are not shown)", and a Token In or Token Out line that nothing named reads "Unknown (could not be decoded)", since the sub-plan may name it.
