After some investigation, Rana found that on the AA filter board end, one of the 4pin LEMOs from the whitening board had one of its wires come unstuck from where it was soldered (this presumably happened while we were squishing cables tonight, as the LR channel was fine before that). Also, there was no heat shrink used on any of the solder joints.

The faulty cable has been re-soldered (with heat shrink) and replaced. All 5 sensor signals appear normal on dataviewer now. I am leaving things in this state for the night, let us see if the glitches return overnight.
