Mx got the info from somewhere, and knew when to change the units out.
Yep. Likely a red light on the panel. Doubt Mx inspected the actual battery to get the notice...

And that could be generated from those separate leads, calculating charging response against an indexed standard?

One thinks the accelerated replacement Program got accelerated straight away after the first two or three unscheduled BATT FAULT prompts.

I think the monitoring is visible on the undamaged Batts on display. Because these cells do not tolerate inclusion of foreign material in the cell itself, temperature monitoring got the short stick.I think the "White Wad" might be the only temperature sensing device?

Is there a temperature sensor that melts at a given value, say 120C that then opens up the circuit, stopping all electrical activity? A variation on a "Fusible Link"? If so, that may be the trigger for the ECAM. No current from the battery'

Didn't ANA report a drop to zero voltage concurrent with the smoke event?
