This is a little bit of a rabbit hole. You disassemble a banebox or vex planetary gear box, grease it, put it back together, Is it no longer COTs item? Attach a cots motor to it. That makes it an assembly? What if the same assembly is available for purchase (COTS)? While most inspectors will pass small violations (pinion pressed on a motor) obviously there is a limit IE assembling a COTs chassis is for beyond this.

This is an area I wish the GDC would clarify in future years.
