Does that help successfully communicate what I mean by a pattern that
computes and stores information about
its surroundings?

This seems like a failure to communicate because of mixing levels
of description. If you're going to define "observer" as a pattern
you need to say what kind of pattern it is.  If you skip to a
functional, "processing and storage" or intentional "engages in"
level of description then you introduce terms with no definite
relation to patterns.

An observer is a pattern in space-time (a physical process) which 
engages in the processing and storage
of information about its surroundings in space-time. Its information 
processing is such that the observer
creates abstracted, isomorphic, representative symbolic models of the 
structures and processes surrounding
it, as well as other, purely abstract informational model structures. 
The observer has subprocesses of itself
which process its representative models in such a way as to model, 
simulate, or calculate relations between
informationally connected local parts of the space-time surroundings of 
the observer. These cognitive
subprocesses also model, simulate, or calculate relations between the 
observer process itself and its
surrounding structures and processes in space-time.

An observer is constrained to exist as a substructure of  an 
informationally self-consistent medium,
and a medium in which notions of change, locality, and metric space and 
time can be defined.

Further, an observer is constrained to exist in a locale which has a 
thermodynamic range of variation,
and a fine-grained structural variety suitable for the random 
coalescence of structures (slow localized processes)
which can attain auto-poietic (pattern-self-sustaining) properties 
relative to alternative patterns of organization of
matter and energy. As a restatement and refinement of that constraint; 
the locale of the observer must be suitable
for the emergence of and growth of stable, organized complex systems 
with adequate degrees of freedom to explore
many possibilities for their form and function. Only in such a 
constrained environment could an observer
general-information-processing-and-epresenting-and-abstracting process 
arise spontaneously and maintain itself
long enough to do meaningful observation of its surroundings.

An observer is constrained to perceive only informationally 
self-consistent states (with respect perhaps to some
notion of locality and metric space-time) that its medium exhibits. It is
conceivable that the medium exhibits other, informationally mutually 
inconsistent states, but any aspect of the
extent of these other pseudo-states of the medium can in principle
not be perceived by any information receiver and processor  such as the 
observer.

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.

Its information processing is such that the observer
creates abstracted, isomorphic, representative symbolic models of the 
structures and processes surrounding
it, as well as other, purely abstract informational model structures.
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.

The observer has subprocesses of itself
which process its representative models in such a way as to model, 
simulate, or calculate relations between
informationally connected local parts of the space-time surroundings of 
the observer. These cognitive

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.
