That's just it- nothing shows up in any log/dmesg; unlike when a non-MS mouse is
detected and I get the notification from the HID layer.

I even did an s/{bt}_debug/{bt}_info/g over all the files in the commit, and when
that mouse is power-cycled it doesn't even make a peep in the logs- it's like it's
not even being seen (vs. several lines when I use my ordinary mouse).

What params should I use for "btmon" so I can send you the output?

Turns out this was a red herring; I always have the adapter.

Where would I go to check that?
