It has been a long time since i've done any sort of setup, but I think Amber has a problem. When I look at her hanging there beside me, I have a nice side view of the 6th string and fretboard and it looks too high at the 12th. Last week I filed the 6th string nut slot a bit, but it still looks too high.
Neck profile is fine. No truss rod adjustment needed.
Today I used my etched string action gauge and got 3mm at the 12th [fretboard to underside of string].. that seems insane. My silk-screened one (the cheap eBay Baroque) says 3.5mm. My eyes are going so I need to shine a very bright COB led on the gauge in order to read it.
Humidity has been in hi-50s most of the summer.

RobertW, I've noticed this from humidity and dryness both. The thinner wood of the body swells and shrinks, or moisturizes and dries much faster than the neck ever will. This means the body will always be moving "a bit" relative to the neck during the seasons. This is speaking about ASW guitars though, not laminate ones.
I don't worry about the action at the 12th fret too much because of this. If the action starts to get bad from the 1st to 6th-ish frets by any noticeable degree though, then I start looking into things and taking action. (Pardon the pun!)
===================================== One Alvarez in the hand is worth two Taylors and a Martin in the guitar store!
'No Recess' has a passage at 12th fret and moves down..it is basically my action test when trying guitars. If the string beside the string i'm depressing is as high as my cuticle..it's way too high. I fact if its past the white part of my finger nail tip, its too high!.
