The carbon fiber sleeves of the new Tesla Plaid rotors, are they direct-wound or pressed-on, @elonmusk?

Fiber is wound over rotor at high tension load. Machine to do this was made by Tesla Automation.
Carbon sleeve must put copper rotor in compression or it loosens at low temp due to differential thermal expansion.
Preload is also helpful for maintaining precise gap to stator.
