Steve, I agree that GR, relativity, DE and DM must be considered. I'm just not there yet.
I take my planckon "field" as given a priori. I have no explanation for its origin. Also, my base (unexplained so far) assumptions are:
1. The size of the subsets that become active in a corpuscle's fermionic partition, Q. In my info theory, Q is parameter. In principle it can vary from one coding field to another. In physical theory, that would mean varying from one corpuscle to another. In fact, the functionality of the model doesn't change qualitatively if you allow Q to vary, at least slightly, through time. But from an info theoretic standpoint, fixed Q is best...and also easiest to analyze mathematically.
2. K, the number of units per CM. Also could vary slightly, from one CM to another, but fixed K is probably optimal and easiest to analyze.
3. complete (all-to-all) connectivity between any two coding fields that are connected. In physical theory, that means between the fermionic partitions of any two corpuscles that are connected.
4. the planckons are binary-valued. Either one is active ("present") at T or inactive ("not present"). This is true for both fermionic and bosonic planckons.
5. so when a code, consisting of Q active planckons (chosen from a fermionic partition consisting of QxK planckons) is active in a corpuscle at T, those Q active planckons send binary signals, to all planckons in each fermionic partition that is connected to the source corpuscle. All of those signals propagate in one discrete time step. And that is true for all signals leaving all corpuscles that comprise the universe. That is, the whole universe updates in lock step. I think the speed of light reflects the number of "hops" made from one corpuscle to the next, as an effect propagates across the single underlying field (which is again, partitioned into corpuscles). Also, again, note that the spatial (topological) "packing" of the fermionic planckons is NOT used in the equations that update the codes. Thus, I make no underlying assumption about the physical packing of the planckons (even though my figures depict the field as having a 3D structure). Formally, the set of fermionic planckons in a corpuscle is just that, a set, i.e., an unordered collection.
I have not yet done any thinking about how my discrete planckon field and discrete time will address Lorentz invariance, local time, etc. But again, note that if the estimate of corpuscle size in the essay is ballpark correct, then the "antialiasing" that my model predicts, would not yet have been probed experimentally.
