For example, if you drag installed 5 apps, APP1, 2, 3, etc, that all

I *think* the answer to this question probably lies here:
https://developer.apple.com/library/archive/documentation/Carbon/Conceptual/LaunchServicesConcepts/LSCConcepts/LSCConcepts.html#//apple_ref/doc/uid/TP30000999-CH202-TP9
The sections on 'Application Registration' and 'Preferred Applications'
are probably the most pertinent - although it isn't entirely clear how
the two mechanisms co-exist: registration suggests the 'most recent'
modification time wise app is stored against a file kind, but preferred
applications suggests that multiple apps are stored but the newest
CFBundleVersion wise is chosen.
Warmest Regards,
Mark.
