Hi Eric:

In my opinion the most such a "pattern" can do is contain current features
that may in part be the result of past collisions with other patterns -
assuming a "History" of some sort exists for this universe.

The current features of a pattern are either the result of deterministic
rules or the rules are at least partly random. Either way I do not see how
the pattern "creates" any part of its current features.

Same comment.

This seems a bit circular re what you said above. Further I seems to me
that a universe whose rule of state succession reads "Completely Random" is
informationally self consistent with that rule.

Snip

I would like to resolve the above first.
