Lookup permissions bug? | inputlookup definedtablename fails

Is this a permissions bug? I can | inputlookup with no search only by filename, not table name in transforms.conf. When all the related files are moved into the search app, the issue goes away.

In app A transforms.conf:
[userlist]
filename = userstats.csv

I used | outputlookup userlist from the Search app to successfully write 200 lines to the file.

Now, I try using inputlookup to read from the file:
search | inputlookup append=t userlist - works
search | inputlookup append=t userstats.csv - works
| inputlookup userstats.csv - works
| inputlookup userlist - fails

Error is Error in 'inputlookup' command: The lookup table 'userlist' is invalid.

I also got an error when trying to run a savedsearch using search ... | inputlookup append=t userlist | outputlookup userlist via the manager -> Saved Searches -> Run.

App A default.meta is:
[]
access = read : [ * ], write : [ admin, power ]
export = system)
