I took this one step further tonight and added a line to the top of
/sbin/dhclient-script to track when it gets triggered.  Here's the line:

	#!/bin/bash
	echo "dhclient-script: `date -R`: $reason" >> /tmp/dhclient.log
	...

I added the same line to dhclient-enter-hook, replacing the prefix
appropriately.

For IPv4, I see the expected PREINIT / BOUND transition written to the
logs.  For IPv6, I only see PREINIT6, yet the interface is configured
with a global IPv6 address.

What is misconfigured?  This has got to be something insanely simple but
masterfully elusive (at the moment.)

Thanks,
Chris
