So which Cocoa classes are actually clusters, and is there a
comprehensive list of them somewhere in the docs?

The five "primitive" NSMutableArray methods are documented in the
first
paragraph of the NSMutableArray entry in the Core Foundation
Reference. So
they are not all that difficult to find:
addObject:
insertObject:atIndex:
removeLastObject
removeObjectAtIndex:
replaceObjectAtIndex:withObject:

From what I have read, here I override the 2 inherited "primitive"

I'm assuming that the mutable version has an additional primitive
that has to be overridden. Unfortunately Apple documentation on Class
Clusters isn't great. Specifically, documenting which classes ARE
class clusters and what the primitive methods for each are. NSData
and NSMutableData documents what primitive methods are, NSArray and
NSMutableArray do not.
I would file bugs on the documentation.

And I believe you'll need to override an additional method for
storing the object in the case of sublcassing NSMutableArray. Not
sure which method that is, as it isn't documented (as far as I can
tell) and I haven't had to do it myself.
Hopefully that helps a bit.
