Can Guests access code? (on

I need to allow certain team members the ability to create and edit issues in a repo but not access the code in any way. The Guest permission level looks like it might fit the bill here as per the Permissions docs but they say a Guest can “Download and browse build artifacts” (not sure what the [^1] means). What are build artifacts? If it’s more of a line or two of code then is it possible to somehow block all code access (viewing or downloading) for a Guest?

I’m hosting my repos on

Many thanks for any advice!
