What should be the proper Unix permissions for files in a locally-written app in $SPLUNK_HOME/etc/apps?

We're installing locally-written Splunk apps via puppet and are curious what the proper permissions for a user-written app under $SPLUNK_HOME/etc/apps should be. The Splunk gui does things as its defaults, which I hope are the correct default case. Is what it does (or what we should do) documented someplace?

Note I do 'not' want to set permissions via the Splunk administrative gui. The questions is what the Unix permissions should be for files in a locally-written app under $SPLUNK_HOME/etc/apps. Thanks.

Here's how i did it (passes app certification on add-on builder now):

find /opt/splunk/etc/apps/myApp/ -type d | xargs chmod 755 $_
find /opt/splunk/etc/apps/myApp/ -type f | xargs chmod 644 $_
find /opt/splunk/etc/apps/myapp/bin/ -type f | xargs chmod 655 $_
chmod 600 /opt/splunk/etc/apps/myapp/app.manifest
chmod 644 /opt/splunk/etc/apps/myapp/README.txt

and here is what i ended up with

UDPATE: Its README not README.txt that is created by the AoB, but i've been using this post over and over again since we wrote it.  Works great.

From the Unix perspective it's all uniform. Should look like -

The fine access administration is really at the Splunk application level documented at Step 5: Set permissions

No, ignore the step 5 stuff, that's not relevant. I'm asking about unix permissions on the filesystem only.

More detail - I'm trying to permit shared group-write for development where a developer could ssh into the search-head and build their app via some combination of manual editing and using the gui to build dashboards etc. If they stay all gui for their development, the app works, but the group and world permissions are getting reset by the gui 'save' actions to something other than the state the tree started with (in general, the group-write gets removed, sometimes even group-read). If they work all interactively in an editor, the app doesn't always work due to needing service resets all the time if they edit any .conf files or the like.

So I'm trying to dig into what the 'unix' filesystem permissions are supposed to be in $SPLUNK_HOME/etc/apps/myappname

Also, the permissions there differ a lot for unix and mac variants of splunk, which I can't explain either. Is there a way to reverse engineer what the splunk gui is setting when you hit 'save' ?
