One related question that hopefully someone could answer.

Some rollups claim that the entire state of the chain can be fully synced from layer 1 (without connecting to other rollup node peers), but how is this possible post 4844 ? If the data will only be available for 30 days ?

I assume that you would need one honest archival rollup node.

It may be that I don't fully understand. But

considering all things involving ZK-Rollups, when the article mentions ZK Roll-ups, does it mean just "validity proof" roll-up or actual ZK (as in succinct and ZK)? Does any of the assumptions change when considering "actual" ZK roll-ups vs ZK roll-ups?
