Another possibility might be to see if there's been backups of the routines being saved. It won't give you the "who" but it could at least give you the "when" a routine was modified & compiled.

You could use the 'Global Lister' and check the rBACKUP global. Here's an example (you may need to tinker with the the global lister input - taking a deeper dive into the ^rBACKUP global may help):

Right margin: 80 =>
Screen size for paging (0=nopaging)? 24 =>
For help on global specifications DO HELP^%G
Global ^rBACKUP("TEST","INT",,0)

or maybe

Global ^rBACKUP("TEST.1","INT",,0)

To really get all the functionality you're looking for, you may need to set up a version control system like git or somesuch.

Hope this helps!

@Robert Cemper - I have verified that the query Detail does exist in 2017.2 (closest I can get) but you are spot on that it needs to be run from the %SYS namespace; I tried two other Ensemble-capable namespaces and it errored out both times.
