Look good in general, left some questions.

Also, this PR set proper block/state pruning arg for the domain chain, we also need to ensure the corresponding consensus block/state are not pruned because they are required by FP generation.

Just some questions about how the code works, overall it makes sense to me.

Edit: none of these are blocking, feel free to resolve or ask me to open a PR instead.

Nit: There are no explicit features or optional dependencies in this crate, and it uses std collections unconditionally:
https://github.com/autonomys/polkadot-sdk/blob/94a1a8143a89bbe9f938c1939ff68abc1519a305/substrate/client/state-db/Cargo.toml

It doesn’t matter much either way, but it’s slightly confusing to suggest there are features we’re not using:

Good enough to merge, I don't mind if you want to tweak that comment (or not).
