Did a read with the WG disabled. No obvious difference in the data visually which isn't unexpected.

I would expect the code plug to start at address 0x8000.? I imagine
you're not decoding the whole address space here, of course.
The firmware seems to start at 0xC000.? A code plug whose first two
bytes are 0xFFFF is a 16k, not a 2k.
It looks like the watchdog lives at 0x4002 and 0x400A.? During startup,
the radio checksums both the firmware and the code plug.? During the
loops, every 0x100-0x200 bytes, it frobs the watchdog.
