can someone point me in the direction on how the main parachute restrictors work. It doesn't seem passive to me because the same force on the chutes are applied for a time until they release and let them open more. Is it a timed release?

Kavandi: SpaceX just wrapped up thermal vacuum testing [of Crew Dragon] at Plum Brook. #AIAAPropEnergy
The AIAA Propulsion and Energy Forum is starting at 8 am EDT with a keynote by NASA Glenn director Janet Kavandi. That’ll be webcast along with some other sessions, such as one later this morning on SLS and Orion:
Yeah, I think that's just a "chute 1" designator, so to speak. And it's not just dragon. They had a similar color scheme on the Orion tests.
It has left Ohio and is on its way to KSC:
In a speech at the American Institute of Aeronautics and Astronautics’ Propulsion and Energy Forum here July 9, Janet Kavandi, director of NASA’s Glenn Research Center, said the spacecraft recently left the center’s Plum Brook Station after a series of thermal vacuum and acoustics tests.“They just left yesterday or today,” she said in her remarks at the conference.

Seems likely they’d cover the glass to prevent debris from damaging the glass in transit.I thought that at first. If it was for protection during shipment, why would the left window have plastic taped over the window while the right one appears to have a bolted-in-place panel?

That makes sense in the same sense as they silvered much of the tail portion of SpaceShip Two. Reflecting heat away is more effective than absorbing it, at least for certain cases.The silver material is NOT for heat reflection.It is the same silver-colored material that is used to cover the primary heat shield on Cargo Dragon, as well as the primary heat shield on Crew Dragon. It is for moisture protection. Given that the exhaust ports for Super Draco are covered in the same material as the primary heat shield (PICA-X) you can expect the same application of silvery material for moisture protection.PICA(-X) is known to absorb moisture (water) from the atmosphere. When absorbed into the PICA material the water negatively influences the performance of PICA as a heat shield material. It is therefore necessary to prevent PICA from absorbing moisture. That is why the PICA is covered in the silvery material as seen in the recent pictures.More on this subject: https://uknowledge.uky.edu/cgi/viewcontent.cgi?article=1083&context=me_etds
