Is there some scenario in which a bed mesh would not successfully be applied? I perform a 5x5 mesh before each print and have a pretty decent measurement range (0.08mm on my last one), but i am seeing variances in first layer that don't seem to match the captured mesh
From same mesh (and orientation) as captured above. the high/low points dont seem to match up with the mesh (see bottom-right is too low and top-right is too high)

If you can see the mesh in the viewer during the print it is active.
I'd suggest you're better off considering what might be causing characteristics the mesh system can't see... what probe are you using?

edit: sorry here are more printer details >
V1.8, stock z endstop nozzle probe, AB/CW with Klicky probe
Bed at 100C, heatsoaked at least 30 min, test print above is ASA at 250C

this is what my understanding was, which is why im so confused
and for additional context i never had (or noticed) this issue until i swapped to an 0.6mm nozzle and started tuning it
possible i just hadnt used the outer edges of my bed in awhile with the 0.4mm so it never presented itself

It's possible you have a toolhead twist issue of some kind. If the toolhead rotates around the x axis (say, from being pulled back by a short umbilical, or a twisted extrusion) that changes the relationship between the probe and the nozzle, which of course is invisible to the meshing system

shouldnt be any resistance from anything pulling it (using chains not umbilical), how best to test for a twisted extrusion. havent come across that before
and if for instance x axis extrusion is twisted, wouldnt that result in the same "defect" across the whole bed along the x axis

No, because it's variation in the roll position that causes the (hypothetical) issue
So a twist on the x axis would lead to a pattern that's consistent along y, if that makes sense
As for measurement, there's this: https://docs.vorondesign.com/community/troubleshooting/badnoob/rail_misalignment_causing_twist.html
And there is klipper's axis twist module

this is what i meant, you phrased it better
thanks for these references i didnt know there was an axist twist compensation built into klipper. i will have to look into both that and the voron doc
