You can reduce warping: slow down, cut the fan, improve bed adhesion, heat the chamber. I haven't tried a heating lamp or draft shield.
Adjusting the tool path/extrusion to match actual dimensions seems most promising. Extruder stepper current increases when you have overextrusion. Moretti 2022 apparently had success measuring the upwards force on the extruder some other way.
VL53L8CH or similar laser distance camera hasn't been used to measure warping. Individual measurements have a big spread (99.7% fall in a 8mm interval) but it's potentially a lot of data (8x8@30Hz), to fit a small number of parameters that describe the deformation.
