"Compass sensor" error after repair

I disassembled my iPhone 14 Pro to clean condensation from behind the camera lenses it took a quick dip in the river. No other signs of liquid damage inside, no liquid sensors tripped, and everything was working fine before disassembly.

Now, after reassembly, the iPhone is boot looping every ~3 minutes, and Apple diagnostics say that the "Compass Sensor Test" fails. Also, the compass does not, in fact, work. I have reseated all visible flex cables; no fix.

Anyone know if this is repairable, or where the compass is located or connects? Can't find anything similar online.

Here is the first section of the panic log:
