Not just social media postings but past real estate listings can probably provide floor plans.

And if you don't have those, a lot of buildings have common patterns. Its very much in the realm of possibility to train a model using exterior and interior information so that you could have AI generate a floor plan using only exterior data.

Combine that with a small drone that could fly around a building and take different wifi signal readings to triangulate access point positions.

Once you have all that don't you have everything you need to detect movement in the building based on signal disruptions?

Yes, seems like a bit of work but it absolutely seems like the type of effort some governments would put effort into.

I regret even engaging with the floor plan debate.

It doesn’t matter if they have a floor plan. That’s not enough information to characterize the RF environment of a house and how it responds to people moving through it.

A floor plan won’t tell you the position of all the WiFi devices, obstructions, and how the environment responds to moving those around. It won’t even tell you where the router is with any precision or if it’s next to a big chunk of metal like a computer case that’s blocking half the house and causing reflections.

It’s a red herring.

That seems like all you'd need anyway, skip the rest of this. Small autonomous drones with simultaneous location and mapping capability will absolutely revolutionize warfare (and firefighting, but I digress) whenever they stop being sci-fi.
