I was just poking around on ev-cpo.com and discovered something interesting: The San Francisco store has a Model S for sale in its inventory that is identical to the one I ordered in mid-January except for the color of the headliner. Comparing its VIN to those of customer-ordered cars suggests that its VIN was assigned during the first week of February, i.e. 1-2 weeks after my car had its VIN assigned. Since the headliner color doesn't seem like something that would affect production scheduling, it seems entirely plausible that my car could have been built instead of (or at least alongside) this particular vehicle. And there are at least two other cars in inventory on the West Coast that have similar VIN numbers and are equipped almost the same as mine (main differences are the decor and no Subzero package). This suggests that Tesla is under some circumstances deliberately producing cars for inventory ahead of cars for which they have confirmed "first available" customer orders. Does this make sense, or is there another plausible explanation?
