.q.en – does it read the sym file from disk every time?
The .Q namespace tools | Reference | kdb+ and q documentation – Kdb+ and q documentation (kx.com)
based on this, it seems .q.en[] reads the sym file from disk every time it is called, which would pick up any updates that are coming from other processes.
However, I am not 100% certain and I am not proficient in reading the k implementation to know whether or not this is the case. I’m hoping someone has done this exercise and can answer it for me.

Hi – yes it does. The corresponding logic block in .Q.en is
(`/:d,s)??,/?:'{$[0h=@x;,/x;x]}’t c // which translates to `:path/to/sym ? distinct raze distinct each (symlist from each column)
