I'll answer the apparmor bit.

Hard links are treated as different paths in apparmor so for a file with 2
links, you may have rules for both or either to access the file. Once it passes
the LSM (AppArmor) it should behave as you expect (eg, if one app is allowed
'w'rite access to one link and the other app is allowed 'w'rite access to the
other link, both apps may modify the file).
