What I'm really asking is there a way to know where they ORIGINATED

There is not. For example, [NSMutableArray array] calls
CFArrayCreateMutable() to do the work, returning an array that's
indistinguishable from the one you get if you call CFArrayCreateMutable
() directly.
#0 0x93628d13 in CFArrayCreateMutable ()
#1 0x9366c0ff in -[__NSPlaceholderArray initWithObjects:count:] ()
#2 0x93679c24 in +[NSArray array] ()
Even if you could find some distinguisher, it would almost certainly
be unsupported and behave differently in past or future OS versions.
