looks like I dodged a bullet not buying any Raspberry Pi RP2350 devices yet. There seems to be a fault in the analogue circuitry of the all the GPIO pins that - under certain circumstances - causes them to output a level of approximately ⅔Vdd.
The "Fixed by: documentation" remedy basically means software workarounds forever or possibly "don't ever do this".
