After a bit of poking, I found what looked to be a textbook quartz crystal resonant curve, but centered at 20 MHz rather than 10. This suggests there’s a divide-by-two in the driver circuit, perhaps to improve the duty cycle to a more perfect 50%. But more importantly, it suggests that neither the crystal itself, nor the electrical connections between it and the package (since I was probing at the package contacts and not the surface of the quartz), were the source of the failure.
