Can you provide some simple or not-so-simple example automata in that language?
Just a data point that support hold_my_fish's argument: Savant Kim Peek did likely memorize gigabytes of information and could access them quite reliably:
Are there different classes of learning systems that optimize for the reward in different ways?
I don't think that shards are distinct - neither physically nor logically, so they can't hide stuff in the sense of keeping it out of view of the other shards.
Also, I don't think "querying for plans" is a good summary of what goes on in the brain.
I'm coming more from a brain-like AGI lens, and my account of what goes on would be a bit different. I'm trying to phrase this in shard theory terminology.
First, a prerequisite: Why do Alice's shards generate thoughts that value Rick's state, to begin with? The Risk-shard has learned that actions that make Rick happy result in states of Alice that are reinforced (Alice being happy/healthy).
Given that, I see the process as follows:
In short: There is no top-down planning but bottom-up action generation. All planning is constructed out of plan fragments that are compatible with all (existing) shards.

Can you provide some links to these groups?
Each needs an environment to do so, but the key observation seems to be that a structure is reliably reproduced across intermediate forms (mitosis, babies, language, society) and build on top of each other. It seems plausible that there is a class of formal representations that describe
You don't talk about human analogs of grokking, and that makes sense for a technical paper like this. Nonetheless, grokking also seems to happen in humans, and everybody has had "Aha!" moments before. Can you maybe comment a bit on the relation to human learning? It seems clear that human grokking is not a process that purely depends on the number of training samples seen but also on the availability of hypotheses. People grok faster if you provide them with symbolic descriptions of what goes on. What are your thoughts on the representation and transfer of the resulting structure, e.g., via language/token streams?
I mean scoring thoughts in the sense of [Intro to brain-like-AGI safety] 3. Two subsystems: Learning & Steering with what Steven calls "Thought Assessors". Thoughts totally get scored in that sense.
About the problems you mention:
the apparent phenomenon of credit assignment improving over a lifetime. When you're older and wiser, you're better at noticing which of your past actions were bad and learning from your mistakes.
I don't get why you see a problem here. More data will lead to better models over time. You get exposed to more situations, and with more data, the noise will slowly average out. Not necessarily because you can clearly attribute things to their causes, but because you randomly get into a situation where the effect is more clear. It mostly takes special conditions to get people out of their local optimum.
without any anti-reinforcement event occurring
And if it looks like this comes in hindsight by carefully reflecting on the situation, that's not without reinforcement. Your thoughts are scored against whatever it is that the brainstem is evaluating. And same as above, earlier or later, you stumble into some thoughts where the pattern is more clearly attributable, and then the weights change.
The main difference between LDAIXI and a human in terms of ontology seems to be that the things the human values are ultimately grounded in senses and a reward tied to that. For example, we value sweet things because we have a detector for sweetness and a reward tied to that. When our understanding of what sugar is changes the detector doesn't, and thus the ontology change works out fine. But I don't see a reason you couldn't set up LDAIXI the same way: Just specify the reward in terms of a diamond detector - or multiple ones. In the end, there are already detectors that AIXI uses - how else would it get input?
